Description

Technical Field

[0001] This invention relates to a marking machine, and more particularly to a marking machine and marking method for marking brake pads. Background Technology

[0002] Existing marking machines are mainly divided into several types: electromagnetic, pneumatic, laser, and electro-etching. Electromagnetic technology relies on electromagnetic force to drive a marking needle to reciprocate across the workpiece surface, marking with a controllable and measurable electrical pulse. The controller measures the frequency between each two pulses to ensure consistent needle impact. Pneumatic technology is computer-controlled; the printing needle performs high-frequency impact motion under the action of compressed air, thus printing a mark of a certain depth on the workpiece. Its disadvantage is that air is compressible, resulting in unstable impact force with each strike. Laser marking machines use a laser beam to create permanent marks on various material surfaces.

[0003] As shown in patent document CN212286301U, a marking machine for processing brake pads is provided. However, this equipment mainly achieves the spacing of each workpiece to be marked on the conveyor by manual means. Specifically, the operator observes the display and presses buttons to accurately move the workpiece to be marked to the printing station and to set the spacing between each workpiece. However, this method increases labor costs and cannot operate effectively for a long time. Summary of the Invention

Therefore, they have no substantial technical significance.

[0082] like Figure 1 As shown, the present invention provides a marking machine, comprising:

[0083] Roller conveyor mechanism 1, with height-adjustable brackets 10 connected to both ends of roller conveyor mechanism 1 respectively;

[0084] A marking assembly is mounted on the roller conveyor mechanism 1. The marking assembly includes a frame 21, a marking machine 22, a vertical moving mechanism 23, a stopping mechanism 24, and a separating mechanism 25. The frame 21 is mounted on the roller conveyor mechanism 1. The marking machine 22 is connected to the frame 21 via the vertical moving mechanism 23. The stopping mechanism 24 is provided on the side of the frame 21 facing away from the forward direction of the roller conveyor mechanism 1, and the separating mechanism 25 is provided on the side of the frame 21 facing away from the forward direction of the roller conveyor mechanism 1.

[0085] The first sensor assembly is located under the marking machine 22 and is connected to the stop mechanism 24 via a controller; the second sensor assembly is located in the separation mechanism 25 and is connected to the separation mechanism 25 via a controller.

[0086] Specifically, the first sensor assembly detects whether the brake pad 4 (i.e., the workpiece to be marked) is under the marking machine 22, and thus the controller determines whether the stop mechanism 24 should stop the brake pad 4. That is, when the brake pad 4 is under the marking machine 22, the controller controls the stop mechanism 24 to stop the brake pad 4; after marking is completed, the controller controls the stop mechanism 24 to lift so that the brake pad 4 can continue to move. The second sensor assembly is used to detect whether the brake pad 4 is under the separating mechanism 25. For information on the working method of the separating mechanism 25, please refer to the following section. Description of the first spacer component 252 and the second spacer component 253.

[0087] This invention, by setting a separating mechanism 25, can separate a row of brake pads 4 conveyed by the roller conveyor mechanism 1 one by one, allowing the brake pads 4 to pass under the marking machine 22 one by one. This avoids the potential accumulation of brake pads 4 under the marking machine 22, and further avoids the deviation of the brake pads 4 caused by the brake pads 4 tilting up when they are accumulated, thus indirectly reducing the error caused by marking. In addition, the invention sets a stopping mechanism 24 to prevent the brake pads 4 from continuing to move during marking. Furthermore, since the separating mechanism 25 allows the brake pads 4 to pass under the marking machine 22 one by one, the stopping mechanism 24 can ensure that the brake pads 4 stop accurately at the marking position, reducing the need for the installation of a brake pad 4 position recognition device and reducing equipment costs. In addition, the invention uses a height-adjustable bracket 10 to adjust the tilt angle of the roller conveyor mechanism 1.

[0088] In order for the marking assembly to descend and then press the brake pad 4 with the pressure block 221, and subsequently reset to avoid obstructing the delivery of the brake pad 4, it is now necessary to enable the marking assembly to move vertically; such as Figure 2 As shown, in order to adjust the height of the marking machine 22, a vertical moving mechanism 23 is now installed on the marking machine 22; as shown... Figure 3 As shown, the vertical moving mechanism 23 includes a vertical support 231, a first linear track assembly 232, and a first push rod assembly 233. The lower end of the vertical support 231 is connected to the frame 21. The first linear track assembly 232 is provided on the front side of the vertical support 231. The first linear track assembly 232 is set along the height direction, and a marking machine 22 is connected to the slider of the first linear track assembly 232. The telescopic end of the first push rod assembly 233 is connected to the marking machine 22. When it is necessary to move the height of the marking machine 22, the user can control the telescopic movement of the first push rod assembly 233 through the controller, thereby causing the first push rod assembly 233 to drive the marking machine 22 to slide on the first linear track assembly 232.

[0089] Because the brake pads may wobble during the marking process, to avoid this wobble and ensure clear markings; Figure 4 As shown, a pressure block 221 is now connected to the lower part of the housing of the marking machine 22, and a shim 222 is connected to the lower part of the pressure block 221; the user can adjust the focal length of the marking machine 22 by adjusting the number of shims 222. Specifically, the pressure block 221 has an arm-shaped structure, and the upper end of the arm-shaped structure is connected to the housing of the marking machine 22; when the marking assembly descends, the two pressure blocks 221 will press the two sides of the brake pad 4 on the roller conveyor, thereby preventing possible shaking of the brake pad 4.

[0090] Because brake pad 4 may not align with the actual marking window area under the marking head during marking, resulting in the lower end of the marking head not being aligned with brake pad 4; therefore, a forward pushing component 3 is now provided, such as... Figure 4 As shown, specifically, the forward pushing component 3 is located under the housing of the marking machine 22; the forward pushing component 3 includes a second push rod component 31, a horizontal plate 32, a second linear track component 33, a sliding plate 34, and a push plate 35; the horizontal plate 32 is fixed to the lower side of the frame 21, and the second linear track component 33 is provided under the horizontal plate 32 in the front-back direction; the sliding plate 34 is slidably connected to the slide rail of the second linear track component 33; the telescopic end of the second push rod component 31 is connected to one side of the sliding plate 34, and the end of the sliding plate 34 facing the marking head is provided with the push plate 35. When it is necessary to push the brake pad 4 under the marking head with the push plate 35, the user can control the telescopic extension of the second push rod component 31 through the controller, so that the sliding plate 34 moves forward, driving the push plate 35 to move; when the brake pad 4 is pushed under the marking head, the first sensor component will detect that the brake pad 4 is in place, and then the marking machine 22 will descend, so that the pressure block 221 presses down on the brake pad 4.

[0091] To simplify the structure and facilitate maintenance, both the first push rod assembly 233 and the second push rod assembly 31 are now pneumatically driven.

[0092] In order to set parallel blocking mechanisms 24 and separating mechanisms 25 on both sides of the marking machine 22 along the direction of the roller conveyor mechanism 1, the frame 21 is set to be parallel to the rods on both sides of the roller conveyor mechanism 1. Preferably, the frame 21 is a rectangular frame structure.

[0093] In order to place the cylinder connected to the second push rod assembly 31 on one side of the forward push assembly 3, an L-shaped fixing plate 30 is now provided. One side of the fixing plate 30 is fixed to a side rod of the frame 21, and the cylinder is inserted through the other side of the fixing plate 30.

[0094] In order to stop the brake pad 4 and prevent it from moving with the rotation of the roller conveyor mechanism 1 before marking is completed, the stopping mechanism 24 specifically includes a third push rod assembly 241 and a limiting plate 242. The third push rod assembly 241 is fixed in the frame 22 by a mounting plate. The telescopic end of the lower end of the third push rod assembly 241 is connected to the limiting plate 242.

[0095] Because the telescopic end of the third push rod assembly 241 may be at a certain distance from the position where the brake pad 4 needs to stop (in the conveying direction of the roller conveyor mechanism 1); such as Figure 4As shown, the length of the limiting plate 242 is set along the length direction of the roller conveyor mechanism 1; specifically, the limiting plate 242 includes a mounting plate 2421, a baffle 2422, a reinforcing rib 2423 and a connecting plate 2424; the mounting plate 2421 is connected to the telescopic end of the third push rod assembly 241, and a connecting plate 2424 is provided between the mounting plate 2421 and the baffle 2422, and a reinforcing rib 2423 is provided under the connecting plate 2424.

[0096] In order to move the brake pads 4 one by one to the marking head of the marking machine 22, the brake pads 4 are now separated one by one by the separation mechanism 25. Specifically, the separation mechanism 25 includes a fixed bracket 251, a first separation component 252 and a second separation component 253. The middle part of the fixed bracket 251 is connected to the frame 21, and the first separation component 252 and the second separation component 253 are provided on both sides of the fixed bracket 251 along the direction of the roller conveyor mechanism 1.

[0097] In this embodiment, the fixing bracket 251 includes a support plate 251b for connecting to the frame 21, mounting plates 251a located on both sides of the support plate 251b, and a connecting plate 251c; the two ends of the connecting plate 251c are respectively fixed to the upper ends of the two mounting plates 251a; the first separating component 252 and the second separating component 253 are respectively installed on the outer surfaces of the two mounting plates 251a. Specifically, First separation component 252 and second separation component 253 Its function is to ensure that there is a brake pad 4 between the two. Workers Law It lies in:

[0098] by Figure 2 For example, in this figure, the conveying direction of the roller conveyor mechanism 1 is from right to left. When the second sensor assembly detects that there is no brake pad 4 between the first separating assembly 252 and the second separating assembly 253 (both are closed by default in the initial state), the second separating assembly 253 is lifted, causing the brake pad 4 to move between the first separating assembly 252 and the second separating assembly 253. After it is in place, the second separating assembly 253 is lowered. When the first sensor assembly indicates that there is no brake pad 4 under it, the first separating assembly 252 is lifted, allowing the brake pad 4 to move under the first sensor assembly for marking. Then the first separating assembly 252 is lowered.

[0099] In order for the first separating component 252 and the second separating component 253 to clamp and separate the two sides of the brake pad 4 through telescopic movement; as Figure 3 As shown, both the first separation component 252 and the second separation component 253 now include a fourth push rod component 254 and a baffle 255; the fourth push rod component 254 is connected to the fixed bracket 251 via a mounting bracket 256, and the baffle 255 is connected to the lower part of the fourth push rod component 254.

[0100] In order to achieve the conveying of brake pads 4, a roller conveyor mechanism 1 is now used to convey brake pads 4; such as Figure 5 and 6 As shown, the roller conveyor mechanism 1 includes two supports 11 located on both sides of the width direction of the roller conveyor mechanism 1, multiple rollers 12, multiple sprockets 13, and multiple chains 14; both ends of each roller 12 are connected to the supports 11 on the same side, and all rollers 12 are arranged at equal intervals between the two supports 11; each roller 12 has a sprocket 13 at both ends, and adjacent sprockets 13 are connected by a chain 14; one sprocket 13 is connected to a drive motor. Since all rollers 12 are driven by multiple chains 14, the rotation speed of all rollers 12 is kept consistent, avoiding the brake pads 4 from moving at inconsistent speeds on the roller conveyor mechanism 1.

[0101] Since the subsequent processes for brake pad 4 may be located at a high or low position, the tilt of bracket 11 needs to be adjusted; for example Figure 2 As shown, in order to achieve the tilt adjustment of the bracket 11, a tilting bracket 111 is provided at one end of each bracket 11. Each tilting bracket 111 includes a base plate 111a, a first hinge seat 111b, a hinge pin 111c, two support bolts 111d, a support plate 111e, and a second hinge seat 111f. The height-adjustable bracket 10 is provided with a base plate 111a, and the base plate 111a is provided with a first hinge seat 111b. Two support bolts 111d are provided on both sides of the base plate 111a. The base plate 111a is fixed to the upper end of the vertical rod 102 by the two support bolts 111d. The second hinge seat 111f is provided under the support plate 111e. The second hinge seat 111f is rotatably connected to the first hinge seat 111b by the hinge pin 111c.

[0102] To allow the height-adjustable bracket 10 to extend and retract vertically, the bracket 11 is tilted; for example... Figure 1 As shown, each vertical rod 102 of the height-adjustable bracket 10 is provided with a fixed bolt on its side. The bolt can slide up and down in the side hole of the foot 103 to adjust the height of the vertical rod 102.

[0103] In order to connect the two vertical bars 102 into one unit and ensure that they are flush, a horizontal bar 101 is now connected between the two vertical bars 102.

[0104] In addition to the above embodiments, the present invention also relates to a method for operating a marking machine; specifically as follows:

[0105] Step 1: The controller determines the subsequent operation based on the positioning status of the first and second sensor components.

[0106] If the first sensor assembly is in place and the second sensor assembly is in place, proceed to step two.

[0107] If the first sensor assembly is in place but the second sensor assembly is not, proceed to step three.

[0108] If the first sensor assembly is not in place, but the second sensor assembly is in place, proceed to step four.

[0109] If the first sensor assembly is not in place, or the second sensor assembly is not in place, proceed to step five.

[0110] Step 2: Wait for the marking machine 22 to finish printing; after printing, the stop mechanism 24 is lifted, wait for the brake pad 4 to move out of the marking machine, the stop mechanism 24 is reset, and the first sensor component is not marked.

[0111] Meanwhile, the second sensor assembly remains marked in place; return to step one;

[0112] Step 3: Wait for the marking machine 22 to finish printing; after printing, the stop mechanism 24 is lifted, wait for the brake pad 4 to move out of the marking machine 22, the stop mechanism 24 is reset, and the first sensor component is not marked in place;

[0113] Simultaneously, the second separation component 253 is raised, waiting for the subsequent brake pad 4 to move between the first separation component 252 and the second separation component 253. The second separation component 253 is reset, and the second sensor is marked as in place; return to step one;

[0114] Step 4: The first separating component 252 is lifted, and the brake pad 4 is moved to the marking machine 22. The first separating component 252 is reset, and the first sensor component is marked in place.

[0115] Meanwhile, the second sensor component marker is not in place; revert to step one;

[0116] Step 5: The second separation component 253 is lifted, and the brake pad 4 is moved between the first separation component 252 and the second separation component 253. The second separation component 253 is reset, and the second sensor component is marked as in place.

[0117] Meanwhile, the first sensor component is still marked as not in place; revert to step one;

[0118] In summary, the present invention, through the separation mechanism 25, enables the individual separation of brake pads 4 on the roller conveyor mechanism 1. Furthermore, the first separation component 252 allows for the release of individually separated brake pads 4 when marking is required, ensuring the brake pads 4 reach the first sensor component. Additionally, the connection between the first sensor component and the marking machine 22 allows the marking machine 22 to mark the brake pads 4 after detecting their arrival. Moreover, the linkage between the stop mechanism 24 and the first sensor component enables the release of brake pads 4 after marking is completed. Finally, the second sensor component located at the separation mechanism 25 detects the presence of brake pads 4 between the first and second separation components 252 and 253, allowing for timely replenishment of brake pads 4 and improving the marking accuracy and efficiency of the entire device.

[0119] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0120] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
