Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drum brake pads, in particular to a code material method and device for facilitating the putting and taking of drum brake pads. BACKGROUND

[0002] Brake pads are key safety parts of automobile brake systems, and the general shape of drum brake pads is tile-shaped with an arc, which is generally formed by heating and pressing powder raw materials. During the pressing and subsequent transportation and processing of brake pads, they need to be clamped, placed and moved. When drum brake pads are packaged after pressing, the existing technology generally stands or buckles the drum brake pads in sequence at the end of the production line, and then stacks them together in parallel. Manual operation is required to put multiple brake pads into a packaging box, and during subsequent processing, manual operation is required to take them out of the packaging box or transportation box. A push rod mechanism or other device is used to push out one brake pad at a time for processing.

[0003] The above-mentioned existing technology has the following technical problems: Although the parallel stacked brake pads occupy a small space, it is convenient to automatically stack or separate them on the production line because the orientation of all brake pads is consistent. However, due to the small gap between adjacent brake pads, it is not convenient to clamp them when putting them into the box or taking them out. When putting them into the box, at least one arc surface and one side surface of the four side surfaces of the brake pad in the horizontal direction are the box or other brake pads, thereby interfering with the movement of the clamping mechanism, preventing the brake pad from being placed in the position where it should be placed. As more and more brake pads are loaded, three or even four surfaces may be interfered, so the equipment cannot be used to automatically code material or take out, and manual coding is required, which reduces work efficiency. SUMMARY

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0030] like Figure 1 , Figure 2 As shown in this embodiment, the stacking method for facilitating the insertion and removal of drum brake pads employs a reverse placement method, utilizing the natural curvature of the brake pads to create a clamping space. Specifically, a group of brake pads is clamped at a time, comprising 4-8 brake pads. Each group of brake pads is arranged parallel to each other in the same direction, and each brake pad is arranged vertically. Figure 1As shown, the inner and outer arc surfaces of each brake pad are located on a vertical arc surface, with the inner arc surface of one brake pad touching the outer arc surface of the adjacent brake pad. During stacking, the inner or outer arc surfaces of adjacent sets of brake pads are arranged opposite each other, creating a gap between them. The clamping device can then insert into this gap to place or pick up the brake pads without colliding with adjacent brake pads or the housing.

[0031] Furthermore, a three-point clamping method is used during clamping. The clamping device is equipped with two front claws and one rear claw arranged in a triangular shape. During clamping, the rear claw is inserted into the center of the inner arc surface of the brake pad to be clamped along the gap between two adjacent sets of brake pads, and the front claws are inserted into both sides of the outer arc surface of the brake pad to be clamped along the gap between two adjacent sets of brake pads.

[0032] Compared with the prior art, the main improvements of the material stacking method of the present invention are: first, the clamping position is three-point clamping, which is stable and reliable; second, the adjacent groups are stacked in opposite directions during placement, so that there is a gap in the clamping position, which facilitates clamping. These two factors work together to enable automatic stacking.

[0033] like Figure 3 , Figure 4 , Figure 5 As shown, the material stacking device for facilitating the placement and removal of drum brake pads of the present invention includes a material preparation device 1 for standing up and grouping brake pads, a robotic arm 2 for clamping brake pads, a translation module 3 for driving the robotic arm to move laterally and longitudinally in a horizontal plane, and a frame 4, wherein the translation module 3 is connected to the frame 4.

[0034] For the material preparation device 1 of the present invention, such as Figure 3 As shown, after the brake pads on the conveyor belt are transported, they slide down the ramp and are then stood up and brought closer by the push plate. Once the required number is reached, the robotic arm 2 moves to that position to clamp the brake pads.

[0035] For the translation module 3 of the present invention, as Figure 3 As shown, it is set on the top of the frame 4 and can drive the robot arm 2 to move in three directions, namely forward and backward, left and right, and up and down, so that the robot arm 2 can hold the brake pad and move it from the material preparation device 1 to the material box 5.

[0036] Furthermore, the robotic arm 2 includes a rotating base 21, a cantilever 22, and a rotating motor 23. The rotating base 21 is fixedly connected to the translation module 3. The rotating motor 23 drives the cantilever 22. The upper end of the cantilever 22 is rotatably connected to the rotating base 21 via a bearing. The lower end of the cantilever 22 is provided with a rotating shaft 24 and two clamps 25. The two clamps 25 are arranged in an X-shape, and the rotating shaft 24 is pivotally connected at the intersection. The robotic arm 2 drives the cantilever 22 to rotate via the rotating motor 23, thereby realizing the aforementioned front-to-back stacking of brake pads. The brake pads are held by the clamps 25, while the rotating shaft 24 remains stationary relative to the cantilever 22. The clamps 25 are driven to rotate relative to the rotating shaft 24 via the telescopic rod 26 described below, thus achieving clamping or releasing.

[0037] For this invention, since the gap between two adjacent sets of brake pads is small, to facilitate clamping when stacking in both directions, a problem that must be solved is that the angle or distance change when the clamp 25 clamps or releases cannot be too large, otherwise a collision will occur. To solve this problem, a telescopic rod 26 is provided above the clamp 25, and the telescopic rod 26 is driven to connect a wedge pressure block 27. The two clamps 25 are provided with wedge locking blocks 28 arranged opposite to each other, and the wedge pressure block 27 is located between the two wedge locking blocks 28. The wedge locking block 28 is provided with an upper inclined surface and a lower inclined surface. The wedge pressure block 27 is provided with a lower contact surface for pressing the lower inclined surface to make the wedge locking block 28 rotate inward, and an upper contact surface for pressing the upper inclined surface to make the wedge locking block 28 rotate outward.

[0038] The lower ends of the two clamps 25 are provided with two front claws and one rear claw arranged in a triangular shape. The two front claws are connected to one of the clamps 25, and the rear claw is connected to the other clamp 25. The rear claw is provided with an arc-shaped surface that matches the center of the inner arc surface of the brake pad, and the front claw is provided with arc-shaped surfaces that match the two sides of the outer arc surface of the brake pad.

[0039] for Figure 5 When the telescopic rod 26 extends upward, the wedge block 27 moves upward, and its upper contact surface abuts against the upper inclined surface of the wedge clamp 28, causing the clamp 25 to open. Conversely, when the telescopic rod 26 retracts downward, the wedge block 27 moves downward, and its lower contact surface abuts against the lower inclined surface of the wedge clamp 28, causing the clamp 25 to clamp. This device converts the extension and retraction of the telescopic rod 26 into the opening and closing of the clamp 25. Since the telescopic rod 26 is located above the rotating shaft 24, the distance between the front and rear claws does not change significantly when the clamp 25 clamps or opens, achieving both clamping and opening while preventing collisions caused by excessive opening angles.

[0040] Furthermore, a material box 5 is placed below the frame 4.

[0041] Furthermore, the cantilever 22 includes two parallel long plates, and the telescopic rod 26, the wedge pressure block 27, and the wedge locking block 28 are all located between the two long plates. Figure 5 The middle and longboard sections were not drawn.

[0042] Furthermore, the telescopic rod 26 is configured as a pneumatic telescopic rod or a hydraulic telescopic rod.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention 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 the present invention without departing from the essence and scope of the technical solutions of the present invention.
