DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1 - Figure 4 and Figure 8 The figure shows an automatic painting equipment for automobile brake pads, including a conveying mesh plate 1 for conveying brake pads, a socket 2 is opened on the conveying mesh plate 1, and also includes a cross bar 3, side frames 4 are fixed at both ends of the cross bar 3, and a plug rod 5 adapted to the socket 2 is fixed at the bottom of the side frame 4. An adjusting tube 6 is sleeved on the outside of the cross bar 3, and both ends of the adjusting tube 6 are rotatably docked with the two side frames 4. A sleeve 7 is rotatably installed on the outside of the adjusting tube 6, and a connecting plate is fixed at both ends of the sleeve 7, and a placing plate 8 for placing brake pads is fixed through the connecting plate. A movable groove 9 is opened on the outside of the sleeve 7, and an adjusting port 10 is also opened on the outside of the sleeve 7, and a positioning part 11 is installed in the movable groove 9. The positioning part 11 is used to clamp and position the brake pads on the placing plate 8, and an adjusting arc plate 12 is fixed at the outer side 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 unloading part 14 is installed on the side frame 4. The unloading operation of the brake pads is facilitated by the unloading part 14.

[0028] In this solution, the socket 2 on the conveying mesh 1 is adapted to the plug rod 5 at the bottom of the side frame 4. After the personnel directly plug the plug rod 5 into the socket 2, they can install the placement plate 8 on the conveying mesh 1, and then use the reciprocating motion of the conveying mesh 1 to enter the water curtain spray booth to spray paint the brake pads;

[0029] Before installing the placement plate 8, the personnel first adjusts the positioning part 11 using the adjustment part 13, and then places several brake pads in sequence, and then uses the positioning part 11 to clamp and position the brake pads, and then follows the conveyor mesh plate 1 into the water curtain spray paint room for painting. After completing the painting, the personnel directly hold the two side frames 4 to transfer the placement plate 8 and multiple brake pads. During the transfer of the brake pads, the stability between the several brake pads is guaranteed to avoid offset. At the same time, after the operation is completed, the personnel only needs to operate the unloading part 14, which can easily unload multiple brake pads at one time. The operation is convenient and easy.

[0030] For further information, see Figure 3 - Figure 8The positioning portion 11 includes two positioning sleeves 15 sleeved in the movable groove 9, a positioning rod 16 is fixed on the positioning sleeve 15, a moving opening 17 for moving the positioning rod 16 is opened on the placement plate 8, an end plate 18 is fixed on the outer side of the sleeve 7 corresponding to the movable groove 9, a positioning spring 19 is sleeved on the outer side of the sleeve 7 for pushing the positioning sleeve 15 to move, and an adjusting rod 20 is fixed on the outer side of the positioning sleeve 15 to fit the outer side of the adjusting arc plate 12;

[0031] In order to ensure the stable movement of the positioning sleeve 15 on the movable groove 9 , a limiting plate 21 is fixed on the outer side of the movable groove 9 , and a limiting opening 22 that fits with the limiting plate 21 is opened on the outer side of the positioning sleeve 15 .

[0032] In this solution, after the brake pad is placed on the placement plate 8, the elastic force provided by the positioning spring 19 is used to push the two positioning sleeves 15 toward the brake pad, and drive the positioning rod 16 to abut against the outside of the brake pad to complete the positioning operation of the brake pad.

[0033] It should be noted that, in order to avoid contact with the outer side of the back plate during positioning, the distance between the top of the positioning rod 16 and the placement plate 8 is designed to be smaller than the thickness of the friction material layer, so that each time positioning is performed, the outer side of the friction material layer is contacted.

[0034] For further information, see Figure 3 - Figure 6 The adjusting portion 13 includes an adjusting gear 23 fixed to the outside of the adjusting tube 6, an adjusting frame 24 is provided on the outside of the side frame 4, a tooth plate 25 meshing with the adjusting gear 23 is fixed to the bottom of the adjusting frame 24, a pull plate 26 is fixed to the top, a connecting rod 27 fixed to the side frame 4 is slidably sleeved on the pull plate 26, a push spring 28 abutting against the pull plate 26 is sleeved on the outside of the connecting rod 27, and a track plate 29 in contact with the outside of the adjusting frame 24 is fixed to the outside of the side frame 4;

[0035] In this solution, when placing multiple brake pads in sequence, the operator first pulls the pull plate 26 to move the pull plate 26 toward the top of the side frame 4, thereby pulling the adjustment frame 24, causing the tooth plate 25 to move upward accordingly, thereby driving the adjustment gear 23 and the adjustment tube 6 to rotate accordingly. The rotation of the adjustment tube 6 will cause the adjustment arc plate 12 to rotate accordingly, counteracting the adjustment rod 20, causing the two positioning sleeves 15 to move outward accordingly, causing the positioning rod 16 to move outward, making it easier for the operator to place the brake pads;

[0036] After the brake pads are placed in order, the pull plate 26 is released. At this time, under the action of the push spring 28, the pull plate 26 and the adjustment frame 24 move downward accordingly. After the tooth plate 25 moves downward, it drives the adjustment gear 23 to rotate in the opposite direction, thereby driving the adjustment tube 6 and the adjustment arc plate 12 to reset accordingly. Under the action of the positioning spring 19, the positioning rod 16 is abutted against the outer side of the friction material layer of the brake pad to position the brake pad.

[0037] For further information, see Figure 3 - Figure 6 The unloading part 14 includes a pulling plate 32 and an adjusting plate 31 fixed to both ends of the placing plate 8. A socket 33 is opened on the adjusting plate 31, and a pulling rod 34 is fixed on the pulling plate 32. The bottom of the pulling rod 34 slides through the socket 33 and is fixed with an abutting ball 35. A reset member 36 is installed on the top of the pulling rod 34. The adjusting plate 31 and the abutting ball 35 are magnetically attracted to each other.

[0038] The reset member 36 includes a docking sleeve 37 that is slidably connected to the top of the pull rod 34 , and the docking sleeve 37 is fixed to the top of the side frame 4 . The outer side of the docking sleeve 37 is covered with a reset spring 38 that is against the top of the side frame 4 and the pull plate 32 .

[0039] In this scheme, the principle of using the unloading part 14 to unload the brake pads is: after the brake pads are painted and subsequently cured, the personnel hold the side frames 4 on both sides, remove the placement plate 8, and then pinch the pulling plate 32 to move up, so that the pulling rod 34 moves up, driving the adjustment plate 31 to tilt correspondingly with the cross bar 3 as the center of the circle, so that the placement plate 8 is turned from a horizontal state to an inclined state, and at the same time, driving the corresponding rotation of the sleeve 7, and the rotation of the sleeve 7 causes the corresponding rotation of the positioning sleeve 15, while the adjusting tube 6 remains stationary, which will cause the adjusting rod 20 to move along the adjusting arc plate 12, so that the positioning sleeve 15 moves outward in the moving groove 9, thereby disengaging from the brake pads and no longer positioning the brake pads. At the same time, the tilting of the placement plate 8 makes it easier for the brake pads to detach from the placement plate 8, so that multiple brake pads can be unloaded at one time, which is more efficient.

[0040] It should also be noted that after each adjustment of the tilt of the placing plate 8, the person releases the pulling plate 32. Under the action of the reset spring 38, the pulling plate 32 and the pulling rod 34 will move downward accordingly. Because 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 be turned from the inclined state to the horizontal state. In order to ensure the horizontal state of the placing plate 8, a limit rod 39 is fixed on the side frame 4 to abut the bottom of the placing plate 8. The limit rod 39 is used to ensure the horizontal position of the placing plate 8.

[0041] In this solution, the specific operation process of painting the brake pads includes the following steps:

[0042] In the first step, the operator first drives the pull plate 26 to move upward, so that the positioning part 11 is in the open state, and then the multiple brake pads are placed on the placement plate 8 in sequence. After the placement is completed, the pull plate 26 is released, and the multiple brake pads are clamped and positioned under the action of the positioning part 11;

[0043] In the second step, the personnel will install the placement plate 8 with the brake pads on the conveying mesh plate 1, use the reciprocating conveying mechanism to move the conveying mesh plate 1 to the water curtain spraying room, and use the rotary spray gun to spray the brake pads;

[0044] In the third step, after the painted conveyor mesh 1 is moved out, personnel hold the two side frames 4 and transfer it to the curing area to cure the paint on the outside of the brake pad;

[0045] In the fourth step, after curing, the personnel hold the two side frames 4, pinch the pulling plate 32, operate the unloading part 14, tilt the placement plate 8, and open the positioning part 11 at the same time. The personnel can easily discharge multiple brake pads at one time and complete the painting process of the brake pads.

[0046] In this solution, during the process of painting the brake pads, personnel place several brake pads in sequence on the placement plate 8 in advance, and use the positioning part 11 to position them. After the subsequent painting is completed, when the conveying mesh plate 1 is returned, they can be directly inserted into the conveying mesh plate 1, making the installation and placement efficiency higher.

[0047] Example 2: Please refer to Figure 5 as well as Figure 6 This embodiment further explains the first embodiment, and the difference lies in the optimization of the adjustment operation of the pull plate 26.

[0048] Specifically, a locking plate 30 is fixed to the top of the side frame 4, a lock buckle is fixed to the bottom of the locking plate 30, and an oblique opening adapted to the lock buckle is opened on the outside of the pull plate 26, wherein the cross-sectional shape of the adjustment frame 24 is L-shaped, and the top of the track plate 29 is against the horizontal end of the adjustment frame 24.

[0049] 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 an upward state for a long time. When the pull plate 26 moves upward, the bevel on the pull plate 26 passes through the lock buckle, so that the lock buckle and the bottom of the pull plate 26 are abutted, completing the temporary locking of the pull plate 26 and keeping the pull plate 26 in an upward state. Therefore, only one person is needed to complete the operation of placing the brake pads. After that, it is only necessary to pull the locking plate 30 outward to disengage the lock buckle from the bottom of the pull plate 26. Under the action of the push spring 28, the pull plate 26 will move downward and stop when the horizontal end of the adjustment frame 24 abuts against the top of the track plate 29. At this time, the adjustment gear 23 is driven to reset and rotate through the tooth plate 25.
