Description

Technical Field

[0001] This invention relates to the field of brake pad manufacturing equipment technology, and in particular to a hot-pressing automatic robotic arm. Background Technology

[0002] Brake pads are a key component of automotive braking systems, and are categorized into disc brake pads and drum brake pads. Drum brake pads, in particular, have an arc-shaped shape and are mostly manufactured using a hot-pressing process to form brake pads from powdered friction material. For example, the applicant filed a Chinese utility model patent on January 26, 2019, entitled "Automatic Hot-Pressure Mold and Hydraulic Press with Automatic Hot-Pressure Mold," with publication number CN209452718U, disclosing an automatic mold and hydraulic press used for hot-pressing. However, the aforementioned patent solution lacks automated equipment for loading and unloading. Therefore, it is necessary to provide a solution for an automated hot-pressing robot capable of automatically loading and unloading the mold and hydraulic press in the brake pad hot-pressing production line. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic hot pressing robot that can perform loading and unloading of brake pads in an automatic hot pressing production line, with a high degree of automation and high efficiency.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a thermoforming automatic manipulator, comprising a frame, a first horizontal slide block slidably disposed on the frame in a horizontal direction, a first horizontal drive member driving the first horizontal slide block, a feeding hopper mounted on the first horizontal slide block, a second horizontal slide block slidably disposed on the frame in a horizontal direction, a second horizontal drive member driving the second horizontal slide block to slide, and a material picking support mounted on the second horizontal slide block. The feeding hopper comprises a hopper body and a base plate hinged to the hopper body. The first horizontal slide block is equipped with an opening and closing cylinder, the piston rod of the opening and closing cylinder is fixed to a connecting seat, the connecting seat is hinged to a connecting rod, and the lower end of the connecting rod is hinged to the base plate. The second horizontal slide block is provided with a discharge cylinder, the piston rod of the discharge cylinder is fixed to a discharge pusher, and the discharge pusher is located above the material picking support.

[0005] By adopting the above technical solution, the material to be processed is in powder form and packaged in bags. The first horizontal drive unit drives the first horizontal slide to move. After the first horizontal slide moves the feeding hopper to the designated position, the opening and closing cylinder drives the bottom plate to flip through the connecting seat and connecting rod, so that the bottom of the feeding hopper opens and the material falls into the hot press mold under the action of gravity.

[0006] After the material is hot-pressed and formed in the hot press mold, the second driving component drives the second horizontal slide to move. The second horizontal slide drives the material pick-up support to hold the formed brake pad. The second horizontal slide moves under the action of the second driving component until the material pick-up support moves the brake pad to the designated position. Then, the unloading cylinder drives the unloading pusher to move. The unloading pusher pushes down the brake pad of the material pick-up support to complete the unloading.

[0007] A further feature of the present invention is that it includes several feeding conveyor belt devices, and the feeding hopper is provided with several material stations, each corresponding to one of the feeding conveyor belt devices.

[0008] By adopting the above technical solution, the feeding conveyor belt device is used to transport materials into the feeding hopper.

[0009] A further provision of the present invention is that a transfer device is provided between the feeding conveyor belt device and the loading hopper, the transfer device including a transfer tray, a push plate located above the transfer tray, a pusher cylinder for driving the push plate to move, a slide rail slidably disposed in the horizontal direction on the frame, and a third horizontal drive member for driving the slide rail to move, the upper end opening of the slide rail facing the feeding conveyor belt device, and the lower end opening facing the transfer tray.

[0010] By adopting the above technical solution, such as directly feeding the material of each feeding conveyor belt device to the material station of the feeding hopper, it is impossible to guarantee the accurate number of bags of material in each material station. Therefore, a movable slide is used to feed the material station of the feeding hopper one by one to ensure that there is one and only one bag of material in each material station.

[0011] A further configuration of the present invention is as follows: the transfer tray is slidably connected to the frame, the frame is equipped with a transfer cylinder, and the piston rod of the transfer cylinder is connected to the transfer tray.

[0012] By adopting the above technical solution, the transfer cylinder can drive the transfer pallet to move. When transferring materials into the hopper, the direction of movement of the transfer pallet is opposite to the direction of movement of the push plate, which can quickly transfer the materials from the transfer pallet to the hopper.

[0013] A further configuration of the present invention is as follows: a frame is mounted on the transfer tray, an adjusting cylinder is mounted on the frame and pointing vertically downwards, and a baffle is fixed to the piston rod of the adjusting cylinder; the baffle rises and then contacts the transfer tray.

[0014] By adopting the above technical solution, when the material moves from the feeding conveyor belt to the transfer tray, the baffle acts as a barrier to prevent the material from moving too far and detaching from the transfer tray. When the material moves from the transfer tray into the feeding hopper, the adjusting cylinder drives the baffle to rise, forming a channel between the baffle and the transfer tray for the material to pass through.

[0015] A further feature of the present invention is that the material receiving support has a cavity in the middle and openings at both ends, and the second horizontal slide has an air pipe passing through the cavity and a soot blowing pipe connected to the air pipe, wherein the soot blowing pipe has a plurality of air outlet holes.

[0016] By adopting the above technical solution, a cavity is set inside the material pick-up tray. Firstly, this can reduce the weight of the material pick-up tray itself, and secondly, it can provide installation space for the air pipe, which can then be used to blow ash off the brake pads.

[0017] A further feature of the present invention is that the second horizontal slide is provided with a rotatable shaft and a rotation adjustment member for driving the shaft to rotate, and the shaft passes through the cavity and is fixed with a limiting seat.

[0018] By adopting the above technical solution, when the material picker supports the brake pad and moves, the rotating shaft can be rotated at a certain angle, so that a portion of the upper surface of the limit seat protrudes from the material picker, thereby preventing the brake pad from detaching from the end of the material picker.

[0019] A further feature of the present invention is that the number of the base plate and the connecting rod are both two.

[0020] A further configuration of the present invention is as follows: the frame includes a main support, a lifting frame slidably disposed on the main support, and a height adjustment mechanism for driving the lifting frame to rise and fall, wherein the first horizontal slide and the second horizontal slide are both connected to the lifting frame.

[0021] By adopting the above technical solution, the height adjustment mechanism can adjust the height of the material pick-up tray and the feeding hopper as needed by adjusting the lifting frame.

[0022] A further feature of the present invention is that it also includes a feeding mechanism, which includes an inclined discharge conveyor belt device, a support platform, a rotatable tilting plate, and a tilting drive for driving the tilting plate to tilt. The upper end of the tilting plate faces the discharge conveyor belt device, and the lower end faces the support platform. The support platform is provided with a stop.

[0023] By adopting the above technical solution, after the brake pads fall from the material pick-up tray to the discharge conveyor belt device, they move from the discharge conveyor belt device to the tilting plate, where they are flipped to an upright position and blocked by the stop. The stop rests on the support platform under its own weight, providing support for the upright brake pads. As multiple brake pads are continuously flipped until they are stacked, the stop can move its position on the support platform under force.

[0024] The beneficial effects of this invention are as follows: This invention uses a transfer device to transfer materials from the feeding conveyor belt to the feeding hopper, which can accurately control the number of material bags in the feeding hopper. Materials are fed into the mold through the feeding hopper, and the brake pads inside the mold are removed by the material pick-up bracket and transferred to the top of the discharge conveyor belt. The discharge cylinder drives the discharge pusher to push the brake pads down from the material pick-up bracket, causing them to fall onto the discharge conveyor belt. The unloading mechanism flips the brake pads to a vertical position and stacks them on the support platform, completing the automatic feeding, automatic removal, and unloading of materials. This achieves a high degree of automation, reduces the labor intensity of workers, and effectively improves production efficiency. Attached Figure Description
