Detailed Implementation

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] Example 1 like Figure 1 and Figure 7 As shown, this invention provides a hot pressing production line for brake shoes. The hot pressing production line includes a hot press 10, a hot press mold 20, a tray device 30, a loading and unloading mechanism 40, a positioning mechanism 50, an oiling mechanism 60, and a brake shoe grinding mechanism 70. The hot press 10 is used to press the brake shoe 202; the hot press mold 20 is correspondingly arranged with the hot press 10; the tray device 30 is arranged on one side of the hot press 10 and is used to place the backing plate 201 to be hot pressed and the polished brake shoe 202; the loading and unloading mechanism 40 is arranged on one side of the hot press 10; the positioning mechanism 50 is arranged on one side of the hot press 10 and is used to position the backing plate 201 and the upper mold 300 that cooperates with the backing plate 201; the oiling mechanism 60 is arranged on one side of the hot press 10 and is used to apply oil to the backing plate 201; the brake shoe grinding mechanism 70 is arranged on one side of the hot press 10 and is used to... After the brake shoe 202 is polished and hot-pressed, the hot-pressing production line is structured as follows: the loading and unloading mechanism 40 places the back of the tile 201 on the pallet device 30 onto the positioning mechanism 50, and then stacks the upper mold 300 that cooperates with the back of the tile 201 onto the back of the tile 201; after the positioning mechanism 50 positions the back of the tile 201 and the upper mold 300, the loading and unloading mechanism 40 places the back of the tile 201 and the upper mold 300 together into the hot-pressing mold 20, the hot-pressing press 10 presses the back of the tile 201 into the brake shoe 202, the loading and unloading mechanism 40 places the pressed brake shoe 202 into the brake shoe polishing mechanism 70 for polishing, and then places the polished brake shoe 202 onto the pallet device 30.

[0020] In the above setup, the loading and unloading mechanism 40 enables mechanized handling of the brake shoe back 201 and brake shoe 202; the hot press 10 and hot press mold 20 enable hot pressing of the brake shoe 202; the positioning mechanism 50 ensures the positioning of the brake shoe back 201 and the upper mold 300 to guarantee the hot pressing accuracy of the brake shoe; the brake shoe grinding mechanism 70 performs precision machining of the brake shoe 202; the oiling mechanism 60 applies oil to the brake shoe 202; and the pallet device 30 handles and stores the brake shoe 202. This integration of the hot press 10, hot press mold 20, pallet device 30, loading and unloading mechanism 40, positioning mechanism 50, oiling mechanism 60, and brake shoe grinding mechanism 70 constructs a hot pressing production line. Through the coordination of these multiple mechanisms, mechanized hot pressing production of brake shoes is achieved. This improves production efficiency and product quality while reducing on-site labor costs and operational risks for on-site workers.

[0021] It should be noted that the hot pressing production line also includes a control system. This control system is connected to the hot press 10, hot pressing mold 20, pallet device 30, loading and unloading mechanism 40, positioning mechanism 50, oiling mechanism 60, and brake shoe grinding mechanism 70, and is used to control the actions of each mechanism. This achieves fully automated and unmanned production of high-friction brake shoe hot pressing, while also improving product quality.

[0022] Specifically, such as Figure 1 and Figure 7 As shown, in one embodiment, the hot press mold 20 is located at the bottom of the hot press 10, the pallet device 30 and the brake shoe grinding mechanism 70 are spaced apart from the hot press 10 in the first direction, the loading and unloading mechanism 40 is disposed between the pallet device 30 and the hot press 10, the positioning mechanism 50 is disposed between the brake shoe grinding mechanism 70 and the hot press 10, and the oiling mechanism 60 is disposed on one side of the hot press 10 in the second direction.

[0023] In the above configuration, the loading / unloading mechanism 40 is positioned between the pallet device 30 and the hot press 10, which effectively shortens the handling distance of the loading / unloading mechanism 40, thereby improving its handling efficiency.

[0024] Specifically, such as Figure 1 and Figure 2As shown, in one embodiment, the tray device 30 includes a brake shoe tray 31 and a backing tray 32, wherein the brake shoe tray 31 and the backing tray 32 are spaced apart. The brake shoe tray 31 is used to hold the polished brake shoes 202; the backing tray 32 is used to hold the backing tiles 201 to be hot-pressed. It also includes an AGV positioning device 33, which is disposed on the brake shoe tray 31 and the backing tray 32. The AGV positioning device 33 works in conjunction with the AGV trolley to facilitate the AGV trolley in finding the current position of the brake shoe tray 31 and the backing tray 32.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, in one embodiment, the loading and unloading mechanism 40 includes a loading and unloading robot arm 41 and a brake shoe gripper 42. The brake shoe gripper 42 is connected to the loading and unloading robot arm 41. The loading and unloading robot arm 41 is used to move the brake shoe gripper 42. The brake shoe gripper 42 is used to grip the back of the tile 201, or the brake shoe gripper 42 is used to grip the brake shoe 202, or the brake shoe gripper 42 is used to simultaneously grip the upper mold 300 and the back of the tile 201 positioned on the upper mold 300.

[0026] It should be noted that the loading and unloading robot arm 41 is an existing structure, which is essentially an industrial robotic arm. The degree of freedom of the industrial robotic arm can be selected according to the actual situation.

[0027] Specifically, such as Figures 3 to 5 As shown, in one embodiment, the brake shoe gripper 42 includes a body 421, a first clamping assembly 422, and at least one second clamping assembly 423. The body 421 has a connecting flange 4211 for connecting to the loading / unloading robot arm 41. The first clamping assembly 422 is disposed on the body 421 and is disposed opposite to the connecting flange 4211. At least one second clamping assembly 423 is disposed on the body 421 and is located on one side of the connecting flange 4211. The first clamping assembly 422 is used to clamp the back of the brake shoe 201, and the second clamping assembly 423 is used to clamp the upper mold 300 and the back of the brake shoe 201 positioned on the upper mold 300.

[0028] In the above configuration, the brake shoe gripper 42 integrates a first clamping component 422 and a second clamping component 423, enabling it to clamp the back of the brake shoe 201 and simultaneously clamp and grasp the upper mold 300 and the back of the brake shoe 201 positioned on the upper mold 300. This improves the integration level of the hot pressing production line and enhances the functionality of the brake shoe gripper 42, thereby increasing the working efficiency of the loading and unloading mechanism 40.

[0029] Specifically, such as Figure 3As shown, in one embodiment, the body 421 is a cube, the connecting flange 4211 is disposed on the first face of the cube, the first clamping assembly 422 is disposed on the second face of the cube, and the second clamping assembly 423 is disposed on the side adjacent to the first face and the second face.

[0030] Specifically, such as Figure 3 As shown, in one embodiment, there are two second clamping components 423, respectively disposed on two sides adjacent to the first and second surfaces. This allows the brake shoe gripper 42 to grip two sets of upper molds 300 and the tile backs 201 positioned on the upper molds 300 simultaneously, thereby improving its gripping efficiency. Furthermore, providing two second clamping components 423 prevents the brake shoe gripper 42 from being unable to grip the upper molds 300 and the tile backs 201 positioned on the upper molds 300 if one second clamping component 423 fails; it is equivalent to providing redundant gripping devices, thereby improving the stability and reliability of the brake shoe gripper 42's operation.

[0031] Specifically, such as Figure 3 and Figure 4 As shown, in one embodiment, the first clamping assembly 422 includes a telescopic cylinder 4221, a first clamping cylinder 4222, and a first clamping claw 4223. The telescopic cylinder 4221 has its fixed end fixed to the body 421; the first clamping cylinder 4222 is disposed on the fixed end; the first clamping claw 4223 is disposed at both ends of the first clamping cylinder 4222; the first clamping cylinder 4222 is a bidirectional motion cylinder, and the first clamping claw 4223 is disposed on the two driving ends of the bidirectional motion cylinder. The first clamping claw 4223 partially extends into the oblique hole 2021 of the tile back 201 to clamp and fix the tile back 201. The drive shaft of the telescopic cylinder 4221 can cooperate with the top center hole 2022 of the tile back 201 to position the first clamping claw 4223.

[0032] In the above configuration, the telescopic cylinder 4221 actuates, with one end of its drive shaft extending into the top center hole 2022 of the brake shoe back 201. The extended portion is adapted to the top center hole 2022, and the drive shaft presses against the top of the brake shoe back 201. This allows the first clamping claw 4223 to be positioned relative to the brake shoe back 201 through the cooperation of the drive shaft and the top center hole 2022, ensuring that the first clamping claw 4223 can partially extend into the oblique hole 2021 of the brake shoe back 201 to clamp and fix the brake shoe back 201. This improves the clamping accuracy of the brake shoe gripper 42. In other words, the first clamping assembly 422 uses the top center hole for positioning and the oblique hole as the gripping point, gripping the brake shoe 202 or the brake shoe back 201 through external clamping.

[0033] Specifically, such as Figure 5As shown, in one embodiment, the second clamping assembly 423 includes a second clamping cylinder 4231 and a second clamping claw 4232. The fixed end of the second clamping cylinder 4231 is disposed on the body 421; the second clamping claws 4232 are respectively disposed at both ends of the second clamping cylinder 4231. The second clamping cylinder 4231 is a bidirectional motion cylinder, and the second clamping claws 4232 are respectively disposed on the two driving ends of the bidirectional motion cylinder. In this way, by bringing the two second clamping claws 4232 close to each other, the upper mold 300 and the backing 201 positioned on the upper mold 300 can be clamped, or the upper mold 300 and the brake shoe 202 positioned on the upper mold 300 can be clamped.

[0034] Specifically, such as Figure 6 As shown, in one embodiment, the positioning mechanism 50 includes a support platform 51, a right-angle baffle 54, a first driving cylinder 52, and a second driving cylinder 53. The support platform 51 is fixed to the ground at its bottom; the right-angle baffle 54 is fixed to the top of the support platform 51 and has a first inner wall surface and a second inner wall surface, the first inner wall surface being perpendicular to the second inner wall surface; the first driving cylinder 52 extends along a first direction and is disposed on the support platform 51, the first driving cylinder 52 being disposed corresponding to the first inner wall surface. The first driving cylinder 52 is used to press the upper mold 300 against the first inner wall surface along the first direction; the second driving cylinder 53, which extends along the second direction and is disposed on the support platform 51, is disposed corresponding to the second inner wall surface, and is used to press the upper mold 300 against the second inner wall surface along the second direction; when the tile back 201 is stacked on the upper mold 300 that cooperates with it, the first inner wall surface and the second inner wall surface contact the tile back 201 to position the tile back 201 on the upper mold 300. That is, the tile back 201 is flush with the side of the upper mold 300.

[0035] Example 2 like Figure 2 As shown, this application also provides a hot pressing production method for brake shoes. The hot pressing production method employs a hot pressing production line and includes the following steps: Grasp the back of the tile from the tray device; Place the tile back onto the oiling mechanism; Apply oil to the back of the tile; Place the upper mold on the positioning mechanism; Place the oiled tile backs onto the upper mold; Position the back of the tile on the upper mold; Simultaneously grasp the back of the tile and the upper mold, and place them inside the hot press mold; The back of the tile is pressed into a brake shoe; Grab the brake shoe and upper mold to the positioning mechanism; Lock the upper mold; Separate the brake shoe from the upper mold; Place the brake shoe on the brake shoe grinding mechanism. Grind the brake shoes; Grab the polished brake shoe to Tray device.

[0036] Furthermore, the hot pressing production method employs a hot pressing production line, which includes the following steps: The loading and unloading mechanism picks up the back of the tile from the pallet device; The loading and unloading mechanism places the tile back onto the oiling mechanism; The oiling mechanism applies oil to the back of the tiles; The loading and unloading mechanism places the upper mold on the positioning mechanism; The loading and unloading mechanism stacks the oiled tile backs onto the upper mold; The positioning mechanism positions the back of the tile on the upper mold; The loading and unloading mechanism simultaneously grabs the tile back and the upper mold, and places them in the hot press mold; A hot press presses the back of the rubber sheet to form the brake shoe; The loading and unloading mechanism picks up the brake shoe and upper mold and places them into the positioning mechanism; The positioning mechanism locks the upper mold; The loading and unloading mechanism separates the brake shoe from the upper mold; The loading and unloading mechanism places the brake shoes on the brake shoe grinding mechanism. The brake shoe grinding mechanism grinds the brake shoes; The loading and unloading mechanism picks up the polished brake shoes and places them onto the pallet device.

[0037] Furthermore, such as Figure 8 As shown, the hot pressing production method specifically includes the following steps: Step S10: The robot (loading and unloading robotic arm) grabs the cold-pressed finished product (corrugated back) from the pallet (corrugated back pallet). Step S20: The robot picks up the workpiece and applies oil. In step S30, the robot places the workpiece on the transfer positioning platform (positioning mechanism); Step S40: The robot positions the upper mold, which has been coated with release agent, and places it on the workpiece; Step S50: The hot press presses the upper mold and the workpiece into the hot press mold; In step S60, the bottom layer mechanism of the mold pushes out the hot-pressed mold; In step S70, the robot picks up the upper mold and the hot pressing mold and places them on the transfer positioning platform; Step S80: The transfer positioning platform clamps the upper mold; Step S90: The robot picks up the workpiece and places it in the grinding station for grinding. In step S100, the robot places the upper mold onto the oiling machine (oiling mechanism) for cleaning and applying release agent, and then places it onto the transfer positioning platform after the application is completed. In step S110, the robot places the polished workpiece (brake shoe) into the finished product tray (brake shoe tray); In step S120, the robot switches to cleaning grippers to clean the inside of the mold.

[0038] Based on the above steps, the loading and unloading mechanism 40 enables mechanized handling of the brake shoe back 201 and brake shoe 202; the hot press 10 and hot press mold 20 enable hot pressing of the brake shoe 202; the positioning mechanism 50 enables positioning of the brake shoe back 201 and the upper mold 300 to ensure the hot pressing accuracy of the brake shoe; the brake shoe grinding mechanism 70 enables fine machining of the brake shoe 202; the oiling mechanism 60 enables coating of the brake shoe 202; and the pallet device 30 enables handling and storage of the brake shoe 202. This integration of the hot press 10, hot press mold 20, pallet device 30, loading and unloading mechanism 40, positioning mechanism 50, oiling mechanism 60, and brake shoe grinding mechanism 70 constructs a hot pressing production line. Through the cooperation of multiple mechanisms, mechanized hot pressing production of brake shoes is achieved. This improves production efficiency and product quality while reducing on-site labor costs and operational risks for personnel.

[0039] It should be noted that the loading and unloading robot arm 41, hot press 10, hot press mold 20, pallet device 30, oiling mechanism 60, brake shoe grinding mechanism 70, and cleaning gripper in this application can all adopt relevant mechanisms and devices in existing technology. Their specific structures will not be described in detail here.
