Description

Technical Field

[0001] This utility model relates to the field of brake pad production equipment technology, and in particular to a brake pad inkjet printing device. Background Technology

[0002] After brake pads are manufactured into finished products, they need to be marked with inkjet printing for identification and packaging. Current inkjet printing technology often only allows for marking on the two larger sides of the brake pad. In actual use, if the marking is printed on the front, it is easy for the marking to wear off and disappear after braking. If it is printed on the back, it is difficult to observe the brake pad's model information after installation.

[0003] The existing invention patent, such as CN118665039A entitled "An Automatic Marking Device for Brake Pads", discloses a conveyor frame, support feet, rotating shaft, conveyor belt, first motor, cleaning component, moving component, marking component, ultraviolet irradiation mechanism, receiving structure, and controller. The cleaning component is provided on one side of the upper part of the conveyor frame and is used to clean the brake pads before marking. The moving component is provided in the middle of the upper part of the conveyor frame.

[0004] Although the above-mentioned device can print codes on brake pads, it is equally difficult to print codes on the sides of the brake pads, resulting in low practicality of the marking effect when the brake pads are actually used. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a brake pad marking device to solve the technical problem that the marking position of existing brake pads is easily worn during use or is difficult to observe directly, resulting in low practicality of the marking effect.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example:

[0023] Reference Figures 1-4 This application relates to a brake pad coding device, comprising a worktable 25, a rotating disk 1 rotatably mounted on the worktable 25, a coaxial lower fixed disk 2 fixed on the rotating disk 1, a coaxial rotating block 3 fixed on the lower fixed disk 2, and an adjustable-height upper fixed disk 4 mounted on the rotating block 3. Figure 2As shown, the rotating block 3 has an annular clearance groove 10, and several springs 11 are installed in the clearance groove 10. Two springs 11 are fixed to the upper fixed plate 4 and the bottom of the clearance groove 10, respectively. Several connecting rods 12 are fixed to the bottom of the upper fixed plate 4. Several connecting grooves 13 are opened downward from the bottom of the clearance groove 10. The connecting rods 12 slide into the connecting grooves 13. The connecting rods 12 are mainly used to prevent the upper fixed plate 4 from rotating on the rotating block 3. The rotating block 3 also has a threaded groove 14. A connecting bolt 15 is rotatably inserted into the upper fixed plate 4. The connecting bolt 15 is threaded into the threaded groove 14, and the nut of the connecting bolt 15 abuts against the top of the upper fixed plate 4. By screwing the connecting bolt 15 in and out, the height of the upper fixed plate 4 on the rotating block 3 can be adjusted, so that brake pads of different specifications can stably abut against the upper fixed plate 4 and the lower fixed plate 2.

[0024] like Figure 1 and Figure 4 As shown, the workbench 25 is provided with an arc-shaped plate 5 for the brake pads to fit against the upper fixed plate 4 and the lower fixed plate 2 in an upright state. Positioning rods 23 are fixed on the workbench 25 and on both sides of the rotating plate 1. Several tension springs 24 are sleeved on both positioning rods 23. The two positioning rods 23 are fixed to the two ends of the arc-shaped plate 5 by the tension springs 24. The arc-shaped plate 5 is mainly used to ensure that the brake pads are in close contact with the upper fixed plate 4 and the lower fixed plate 2 during the coding process. The tension springs 24 on both sides of the arc-shaped plate 5 can limit the contact of brake pads of different thicknesses.

[0025] like Figure 1 As shown, the worktable 25 is equipped with a driving component for driving the rotating disk 1 to rotate. The driving component includes a drive motor 8 and a drive rod 9. The drive motor 8 is fixed on the worktable 25, and the drive rod 9 is fixed on the output end of the drive motor 8. The other end of the drive rod 9 is coaxial with the rotating block 3 and fixed to the axis of the rotating block 3. This arrangement can effectively drive the drive rod 9 to rotate through the drive motor 8, and drive the rotating block 3 and the upper fixed disk 4, lower fixed disk 2 and rotating disk 1, which are coaxially fixed to the rotating block 3 in sequence, to rotate.

[0026] like Figure 1 The worktable 25 is equipped with a vertical fixed rod 6. An inkjet printer 7 for marking brake pads is adjustablely mounted on the fixed rod 6. A sensor 16 for detecting passing brake pads is also adjustablely mounted on the fixed rod 6. The inkjet printer 7 is located above the sensor 16. Both the inkjet printer 7 and the sensor 16 are common technologies in this field, and their specific structures will not be described in detail here.

[0027] like Figure 1 and Figure 3As shown, two fixing members are slidably mounted on the fixing rod 6. Adjusting rods 17 are mounted on both the inkjet printer 7 and the sensor 16. The two adjusting rods 17 are horizontally slidably mounted on the two fixing members. Each fixing member includes a fixing block 26 and two fixing bolts 18. Two opposing first locking blocks 19 are fixed to one end of the fixing block 26. A first arc-shaped groove 20 for clamping the fixing rod 6 is opened on the opposite side of the two first locking blocks 19. One fixing bolt 18 is threaded between the ends of the two first locking blocks 19 furthest from the fixing block 26. Two opposing second locking blocks 21 are fixed to the other end of the fixing block 26. A second arc-shaped groove 22 for clamping the adjusting rod 17 is opened on the opposite side of the two second locking blocks 21. Another fixing bolt 18 is threaded between the ends of the two second locking blocks 21 furthest from the fixing block 26. This configuration, via the first arc-shaped groove 20 between the two first locking blocks 19, allows the fixing block 26 to slide on the fixing rod 6. The fixing bolts 18 tighten the ends of the two first locking blocks 19, positioning the fixing block 26 on the fixing rod 6. Similarly, via the second arc-shaped groove 22 between the two second locking blocks 21, the adjusting rod 17 slides between them. The fixing bolts 18 tighten the ends of the two second locking blocks 21, positioning the adjusting rod 17 on them. This allows for adjustment of the height and extension length of the inkjet printer 7 and the sensor 16, further enabling the device to be used with brake pads of different specifications.

[0028] Working principle:

[0029] During installation, first adjust the upper fixing plate 4 according to the height of the brake pad. By screwing in and out the connecting bolts 15, the upper fixing plate 4 is adjusted by the rebound of several springs 11 on the rotating block 3 and the abutment of the nuts of the connecting bolts 15. Then, by unscrewing the two fixing bolts 18, adjust the height of the two fixing blocks 26 on the fixing rod 6, and adjust the extension length of the adjusting rod 17 so that the inkjet printer 7 and the sensor 16 are in the appropriate position. Finally, screw in the two fixing bolts 18. It is worth mentioning that the nozzle of the inkjet printer 7 can be located on the side of the brake pad near the inner circle to further prevent the inkjet from disappearing after wear.

[0030] In use, the brake pad is placed between the arc plate 5 and the rotating block 3, and the brake pad is placed on the rotating disk 1. The arc plate 5 limits the movement of the inner circle of the brake pad to abut against the upper fixed disk 4 and the lower fixed disk 2. The friction between the brake pad and the upper fixed disk 4 and the lower fixed disk 2 is greater than the friction with the arc plate 5, thereby driving the brake pad to rotate. When it moves to a position that the sensor 16 can sense, the inkjet printer 7 prints a code on the side wall of the brake pad.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
