Description

Technical Field

[0001] The present invention relates to the technical field of brake pad processing equipment, and particularly to an automatic painting equipment for automotive brake pads. Background Art

[0002] Brake pads are the most critical safety components in the automotive braking system, which mainly consist of structures such as a friction material layer, a heat insulation layer, an adhesive layer, and a back plate.

[0003] The existing painting equipment for automotive brake pads mainly consists of a spraying execution system, a conveying and positioning system, a water curtain painting booth, etc. A number of brake pads are placed on a conveying mesh plate and conveyed into the water curtain painting booth. Then, an electrostatic spray gun in the spraying execution system is used to spray paint on the back plates of a number of brake pads. In the traditional painting process, after a number of brake pads are sprayed, workers need to transfer the conveying mesh plate into an infrared curing furnace to cure the paint. A number of brake pads are placed on the conveying mesh plate at equal intervals. However, due to the lack of positioning of the brake pads, during the process of transferring the conveying mesh plate before and after spraying, the brake pads are easily displaced, resulting in adjacent brake pads being in contact with each other, affecting the spraying quality and also the curing of the paint during subsequent curing. It is also rather cumbersome for workers to pick up the brake pads one by one. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic painting equipment for automotive brake pads to solve the problem that adjacent brake pads are easily in contact with each other during the transfer due to the lack of positioning of the brake pads during the painting process as mentioned in the above background art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Example 1: Please refer to Figure 1 - Figure 4 and Figure 8 , an automatic painting device for automobile brake pads in the figure, including a conveying mesh plate 1 for conveying brake pads. There are insertion holes 2 on the conveying mesh plate 1. It also includes a cross bar 3. Side frames 4 are fixed at both ends of the cross bar 3. A plug rod 5 adapted to the insertion hole 2 is fixed at the bottom of the side frame 4. An adjusting tube 6 is sleeved outside the cross bar 3. Both ends of the adjusting tube 6 are rotatably docked with the two side frames 4. A sleeve 7 is rotatably installed outside the adjusting tube 6. Connecting plates are fixed at both ends of the sleeve z. A placing plate 8 for placing brake pads is fixed through the connecting plates. A moving groove 9 is opened on the outside of the sleeve 7. An adjusting opening 10 is also opened on the outside of the sleeve 7, and a positioning part 11 is installed in the moving groove 9. The positioning part 11 is used for clamping and positioning the brake pads on the placing plate 8. An adjusting arc plate 12 is fixed on the outside of the adjusting tube 6 corresponding to the positioning part 11. An adjusting part 13 for driving the adjusting tube 6 to rotate is installed on the side frame 4, and a discharging part 14 is installed on the side frame 4. The discharging part 14 facilitates the discharging operation of the brake pads; In this solution, the insertion holes 2 on the conveying mesh plate 1 and the plug rods 5 at the bottom of the side frames 4 are mutually adapted. After the personnel directly insert the plug rods 5 into the insertion holes 2, the placing plate 8 can be installed on the conveying mesh plate 1. Then, the conveying mesh plate 1 is reciprocated into the water curtain painting room to perform the painting operation on the brake pads; Before installing the placing plate 8, the personnel first use the adjusting part 13 to adjust the positioning part 11, then place several brake pads in sequence, and then use the positioning part 11 to clamp and position the brake pads. Then, it follows the conveying mesh plate 1 into the water curtain painting room for painting. After the painting is completed, the personnel directly hold the two side frames 4 to transfer the placing plate 8 and multiple brake pads. During the transfer of the brake pads, the stability between several brake pads is ensured to avoid deviation. At the same time, after the operation is completed, the personnel only need to operate the discharging part 14, and can conveniently unload multiple brake pads at one time, and the operation is convenient and fast.

[0020] Further, refer to Figure 3 - Figure 8 , the positioning part 11 includes two positioning sleeves 15 sleeved in the moving groove 9. A positioning rod 16 is fixed on the positioning sleeve 15. A moving opening 17 for the movement of the positioning rod 16 is opened on the placing plate 8. An end plate 18 is fixed on the outside of the sleeve 7 corresponding to the moving groove 9. A positioning spring 19 for pushing the positioning sleeve 15 to move is sleeved outside the sleeve 7. An adjusting rod 20 that fits with the outside of the adjusting arc plate 12 is fixed on the outside of the positioning sleeve 15; Among them, in order to ensure the stable movement of the positioning sleeve 15 on the moving groove 9, a limiting plate 21 is fixed on the outside of the moving groove 9, and a limiting opening 22 that fits with the limiting plate 21 is opened on the outside of the positioning sleeve 15.

[0021] In this solution, after placing the brake pads on the placement plate 8, the elastic force provided by the positioning spring 19 is utilized to push the two positioning sleeves 15 towards the brake pads, driving the positioning rods 16 to abut against the outer side of the brake pads, thus completing the positioning operation of the brake pads.

[0022] It should be noted that during the positioning process, in order to avoid contacting the outer side of the back plate, the distance between the top of the positioning rod 16 and the placement plate 8 is designed to be less than the thickness of the friction material layer, so that each time it is positioned, it abuts against the outer side of the friction material layer.

[0023] Furthermore, referring to Figure 3 - Figure 6 , the adjusting part 13 includes an adjusting gear 23 fixed to the outer side of the adjusting tube 6. An adjusting frame 24 is arranged on the outer side of the side frame 4. A toothed plate 25 meshing with the adjusting gear 23 is fixed to the bottom of the adjusting frame 24, and a pulling plate 26 is fixed to the top. A connecting rod 27 fixed to the side frame 4 is slidably sleeved on the pulling plate 26. A pushing spring 28 abutting against the pulling plate 26 is sleeved on the outer side of the connecting rod 27. A track plate 29 fitting against the outer side of the adjusting frame 24 is fixed to the outer side of the side frame 4; In this solution, when successively placing multiple brake pads, the operator first pulls the pulling plate 26, causing the pulling plate 26 to move towards the top of the side frame 4, thereby pulling the adjusting frame 24, causing the corresponding upward movement of the toothed plate 25, thereby driving the corresponding rotation of the adjusting gear 23 and the adjusting tube 6. When the adjusting tube 6 rotates, the adjusting arc plate 12 will correspondingly rotate and abut against the adjusting rod 20, causing the two positioning sleeves 15 to move outwards correspondingly, and the positioning rods 16 to move outwards, facilitating the operator to place the brake pads; After successively placing the brake pads, when the pulling plate 26 is released, at this time, under the action of the pushing spring 28, the pulling plate 26 and the adjusting frame 24 move downward correspondingly. After the toothed plate 25 moves downward, it drives the adjusting gear 23 to rotate in the reverse direction, thereby driving the corresponding reset of the adjusting tube 6 and the adjusting arc plate 12. Under the action of the positioning spring 19, the positioning rods 16 abut against the outer side of the friction material layer of the brake pads to position the brake pads.

[0024] Furthermore, referring to Figure 3 - Figure 6 , the unloading part 14 includes a pulling plate 32 and adjusting plates 31 fixed to both ends of the placement plate 8. Sockets 33 are formed on the adjusting plates 31. A pulling rod 34 is fixed to the pulling plate 32. The bottom of the pulling rod 34 slidably penetrates through the socket 33 and is fixed with an abutting ball 35. A reset member 36 is installed at the top of the pulling rod 34. The adjusting plate 31 and the abutting ball 35 are magnetically attracted to each other; Among them, the reset member 36 includes a docking sleeve 37 slidably sleeved on the top of the pulling rod 34. The docking sleeve 37 is fixed to the top of the side frame 4. A reset spring 38 abutting against the top of the side frame 4 and the pulling plate 32 is sleeved on the outer side of the docking sleeve 37.

[0025] In this solution, the principle of discharging the brake pads by the discharging part 14 is as follows: after the brake pads are painted and subsequently cured, the operator holds the side frames 4 on both sides, removes the placing plate 8, then pinches the pulling plate 32 and moves it upward, so that the pulling rod 34 moves upward, driving the corresponding adjusting plate 31 to tilt with the cross bar 3 as the center, thereby making the placing plate 8 turn from the horizontal state to the inclined state. At the same time, the sleeve 7 is driven to rotate correspondingly. When the sleeve 7 rotates, the positioning sleeve 15 rotates correspondingly. Since the adjusting pipe 6 remains stationary, the adjusting rod 20 will move along the adjusting arc plate 12, so that the positioning sleeve 15 moves outward in the moving groove 9 correspondingly, thus disengaging from the brake pads and no longer positioning the brake pads. At the same time, the inclination of the placing plate 8 makes it easier for the brake pads to separate from the placing plate 8, enabling multiple brake pads to be discharged at one time with higher efficiency.

[0026] It should also be noted that after each adjustment of the inclination of the placing plate 8, when the operator releases the pulling plate 32, under the action of the return spring 38, the pulling plate 32 and the pulling rod 34 will move downward correspondingly. Since the adjusting plate 31 and the abutting ball 35 are magnetically attracted to each other, the adjusting plate 31 and the placing plate 8 will turn from the inclined state to the horizontal state correspondingly. To ensure the horizontal state of the placing plate 8, a limiting rod 39 that abuts against the bottom of the placing plate 8 is fixed on the side frame 4, and the limiting rod 39 is used to ensure the limitation of the horizontal state of the placing plate 8.

[0027] In this solution, the specific operation process of painting the brake pads includes the following steps: First step, the operator first drives the pull plate 26 upward to make the positioning part 11 in the open state. Subsequently, a plurality of brake pads are placed on the placing plate 8 in sequence. After the placement is completed, the pull plate 26 is released, and under the action of the positioning part 11, the clamping and positioning of the plurality of brake pads are realized; Second step, the operator installs the placing plate 8 with the placed brake pads on the conveying mesh plate 1, and uses the reciprocating conveying mechanism to move the conveying mesh plate 1 into the water curtain spraying booth, and sprays the brake pads with a rotating spray gun; Third step, after the sprayed conveying mesh plate 1 is moved out, the operator holds the two side frames 4 and transfers it to the curing area to cure the paint on the outer side of the brake pads; Fourth step, after curing, the operator holds the two side frames 4 and pinches the pulling plate 32, controls the discharging part 14 to make the placing plate 8 inclined, and at the same time opens the positioning part 11, so that the operator can easily discharge multiple brake pads at one time, completing the painting process of the brake pads.

[0028] In this solution, during the process of painting brake pads, several brake pads are placed on the placement plate 8 in advance by personnel and positioned using the positioning part 11. After the subsequent painting is completed, when the conveying mesh plate 1 retracts, it can be directly inserted onto the conveying mesh plate 1, resulting in higher installation and placement efficiency. Embodiment 2: Please refer to Figure 5 and Figure 6 , this embodiment further elaborates on Embodiment 1, and the difference lies in the optimization of the adjustment operation of the pull plate 26.

[0029] Specifically, a locking plate 30 is fixed to the top of the side frame 4, and a locking buckle is fixed to the bottom of the locking plate 30. An inclined opening adapted to the locking buckle is formed on the outer side of the pull plate 26. Among them, the cross-sectional shape of the adjusting frame 24 is L-shaped, and the top of the track plate 29 abuts against the horizontal end of the adjusting frame 24.

[0030] In this solution, since it takes a certain amount of time to place the brake pads, it is necessary to keep the pull plate 26 in the upward movement state for a long time. When the pull plate 26 moves upward, after the inclined opening on the pull plate 26 passes through the locking buckle, the locking buckle abuts against the bottom of the pull plate 26, completing the temporary locking of the pull plate 26 and keeping the pull plate 26 in the upward movement state. Therefore, only one person is required to complete the placement operation of the brake pads. After that, only need to pull the locking plate 30 outwards to make the locking buckle disengage from the bottom of the pull plate 26. Under the action of the pushing spring 28, the pull plate 26 will move downward and stop when the horizontal end of the adjusting frame 24 abuts against the top of the track plate 29. At this time, the rack 25 drives the adjusting gear 23 to reset and rotate.
