Description

Technical Field

[0001] This utility model relates to the field of brake pad and brake lining testing technology, specifically a brake pad and brake lining testing device. Background Technology

[0002] Brake pads are the most critical safety component in a car's braking system. The effectiveness of braking depends entirely on the brake pads. Brake pads generally consist of a steel plate, an adhesive heat-insulating layer, and friction pads. The heat-insulating layer is made of a non-heat-conducting material for heat insulation. The friction pads are composed of friction materials and adhesives, and during braking, they are pressed against the brake disc and brake drum to generate friction, thus achieving the purpose of decelerating and braking the vehicle. The working principle of braking mainly relies on friction. The friction between the brake pads and the brake disc (drum) and the tires and the ground converts the kinetic energy of the vehicle's movement into heat energy, bringing the car to a stop. A good and efficient braking system must provide stable, sufficient, and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities to ensure that the force applied by the driver from the brake pedal is fully and effectively transmitted to the master cylinder and wheel cylinders, and to avoid hydraulic failure and brake fade caused by overheating.

[0003] During the production process, brake pad linings may have some products with thickness deviations from the standard thickness. It is not easy to accurately screen out defective products by visual inspection alone, thus affecting the pass rate of the finished product.

[0004] Therefore, it is necessary to design a brake pad / brake lining detection device to improve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a brake pad / brake lining inspection device. This device aims to solve the technical problem that the accuracy of manual judgment and screening of defective brake pad linings is low under existing technologies, which affects the finished product qualification rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A brake pad / brake lining testing device includes a testing platform. An intermittent conveyor belt is mounted on the top of the testing platform. A testing frame is mounted on the top right side of the testing platform. A first material pusher assembly is mounted on the side of the testing frame. An infrared receiver is mounted on the testing frame above the first material pusher assembly. A mounting block is fixedly connected to the top side of the testing frame above the intermittent conveyor belt. A controller is mounted on the top of the mounting block. A measuring component is mounted on the bottom of the mounting block. An infrared transmitter is mounted on the bottom of the mounting block next to the measuring component. A guide roller frame is mounted on the top left side of the testing platform. A second material pusher assembly is mounted below the guide roller frame on the side of the testing platform. A set of discharge ports is provided on the side of the testing platform corresponding to both the first and second material pusher assemblies.

[0008] Preferably, the top of the discharge port is rotatably connected to three sets of guide wheels, and the outer side of the testing platform is fixedly connected to a discharge slope below the discharge port. The discharge slope is designed with an inclined angle.

[0009] Preferably, the first material pushing component consists of an electric push rod and a material pushing frame. The electric push rod is installed on the outer bag of the detection frame on the detection table. The material pushing frame is fixedly connected to the side of the electric push rod corresponding to the position of the material pushing frame. The material pushing frame has a U-shaped structure design. The second material pushing component has the same internal structure as the first material pushing component.

[0010] Preferably, the controller is electrically connected to the intermittent conveyor belt, the electric push rod, the infrared receiver, and the infrared transmitter via wires, with the transmitting end of the infrared transmitter corresponding to the receiving end of the infrared receiver.

[0011] Preferably, the measuring assembly consists of a telescopic rod, a return spring, a connecting frame, a shielding frame, and a bonding roller.

[0012] Preferably, the bottom of the mounting block is fixedly connected to two sets of telescopic rods, the outer side of the telescopic rods is fitted with a return spring, the bottom of the telescopic rods is fixedly connected to a connecting frame, the connecting frame is fixedly connected to a shielding frame at a position corresponding to the infrared transmitter, and the bottom of the connecting frame is rotatably connected to a bonding roller.

[0013] Preferably, a cross guide roller is rotatably connected to the bottom of the guide roller frame, and an anti-slip pad is provided on the outer side of the cross guide roller. Four sets of pressure-sensitive blocks are installed on one side of the guide roller frame and at a position corresponding to the cross guide roller. The second material pushing assembly and the pressure-sensitive blocks are electrically connected to the controller through wires.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The intermittent conveyor belt carries the liner to be tested under the measuring component. When the liner thickness is qualified, the top of the liner is attached to the bottom of the bonding roller and passes under the measuring component. Then it is conveyed to the bottom of the cross guide roller. The cross guide roller is attached to the top of the liner through the anti-slip pad. As the liner is conveyed, it rotates and contacts the pressure block, causing the pressure block to contract under force. The feedback is sent to the controller through the wire, which drives the second pair of pusher components to push the qualified liner into the left discharge port for discharge.

[0016] 2. When the liner thickness is less than the acceptable standard, the liner does not contact the bonding roller and cross guide roller when passing through them. This type of liner is directly conveyed to the end of the intermittent conveyor belt for screening. When the liner thickness is greater than the acceptable standard, the return spring, through its own elasticity, drives the telescopic rod to contract under force, pulling the connecting frame to raise the bonding roller, so that the bonding roller is in contact with the top of the liner. When the connecting frame rises, it causes the shielding frame to be placed on the outside of the infrared transmitter to block the infrared emitting end. The infrared receiver feeds back to the controller through the wire, controlling the pushing component to push the defective liner out through the discharge port on the right side, improving the accuracy of screening.

[0017] 3. Pushing component one uses an electric push rod to push the defective liner to the right discharge port for unloading via the pusher frame. The guide wheel assists the defective liner to slide smoothly down the discharge slope for unloading, so that the defective liner leaves the intermittent conveyor belt and is easy for workers to recycle and process. Pushing component two pushes the qualified liner to the left discharge port for unloading, so that workers can collect the qualified liner. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] This utility model provides a brake pad / brake lining inspection device, which aims to solve the technical problem that the accuracy of manual judgment and screening of defective brake pad linings is low under the existing technology, which affects the finished product qualification rate.

[0028] Please see Figures 1-6 This embodiment provides a brake pad / brake lining testing device, including a testing platform 1. An intermittent conveyor belt 101 is installed on the top of the testing platform 1. The intermittent conveyor belt 101 passes the lining to be tested under the measuring component 205 for testing. A set of discharge ports 102 are opened on the side of the testing platform 1 corresponding to the first pusher component 201 and the second pusher component 4. Three sets of guide wheels 1021 are rotatably connected to the top of the discharge ports 102. A discharge slope 103 is fixedly connected to the outer side of the testing platform 1 below the discharge ports 102. The discharge slope 103 is designed with an inclined angle structure. The guide wheels 1021 assist the lining to slide smoothly down the discharge slope 103 for discharge, so that the qualified lining and the defective lining are separated and leave the intermittent conveyor belt 101 through the discharge ports 102 on the left and right sides, which is convenient for workers to collect and process.

[0029] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5A testing frame 2 is installed on the top right side of the testing platform 1. A pusher assembly 201 is installed on the side of the testing platform 1 on the testing frame 2. The pusher assembly 201 consists of an electric push rod 2011 and a pusher frame 2012. The electric push rod 2011 is installed on the outer side of the testing platform 1 on the testing frame 2. The pusher frame 2012 is fixedly connected to the side of the electric push rod 2011 corresponding to the position of the pusher frame 2012. The pusher frame 2012 has a U-shaped structure design. The electric push rod 2011 passes through the pusher frame 2012. 012 pushes the screened liner to the discharge port 102 for discharge. The detection frame 2 is located above the pusher assembly 201 and is equipped with an infrared receiver 202. The top side of the detection frame 2 is fixedly connected to the intermittent conveyor belt 101 above the detection frame 2. The top of the detection frame 2 is equipped with a controller 204. The controller 204 is electrically connected to the intermittent conveyor belt 101, the electric push rod 2011, the infrared receiver 202 and the infrared transmitter 206 through wires.

[0030] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A measuring component 205 is installed at the bottom of the mounting block 203. The measuring component 205 consists of a telescopic rod 2051, a return spring 2052, a connecting frame 2053, a shielding frame 2054, and a bonding roller 2055. Two sets of telescopic rods 2051 are fixedly connected to the bottom of the mounting block 203. A return spring 2052 is sleeved on the outside of the telescopic rod 2051. A connecting frame 2053 is fixedly connected to the bottom of the telescopic rod 2051. A shielding frame 2054 is fixedly connected to the connecting frame 2053 at a position corresponding to the infrared emitter 206. The bottom of 53 is rotatably connected to a bonding roller 2055. When the thickness of the liner is greater than the qualified standard, the return spring 2052 drives the telescopic rod 2051 to contract through its own elasticity, pulling the connecting frame 2053 to drive the bonding roller 2055 to rise, so that the bonding roller 2055 is in contact with the top of the liner. When the connecting frame 2053 rises, it drives the shielding frame 2054 to be sleeved on the outside of the infrared transmitter 206 to block the infrared emitting end, so that the infrared receiver 202 can give feedback to the controller 204 through the wire to drive the pusher assembly 201 to work.

[0031] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 An infrared transmitter 206 is mounted on the bottom of the mounting block 203 on one side of the measuring component 205. The transmitting end of the infrared transmitter 206 corresponds to the receiving end of the infrared receiver 202.

[0032] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 6A guide roller frame 3 is installed on the top left side of the testing platform 1. A cross guide roller 301 is rotatably connected to the bottom of the guide roller frame 3. An anti-slip pad 302 is provided on the outer side of the cross guide roller 301. Four sets of pressure-sensitive blocks 303 are installed on one side of the guide roller frame 3 and at a position corresponding to the cross guide roller 301. The second pusher assembly 4 and the pressure-sensitive blocks 303 are electrically connected to the controller 204 through wires. The second pusher assembly 4 is installed below the guide roller frame 3 on the side of the testing platform 1. The second pusher assembly 4 has the same internal structure as the first pusher assembly 201. When the lining thickness is qualified, the top of the lining is attached to the bonding roller 2055, and the bottom passes through the measuring assembly 205. The lining is conveyed to the bottom of the cross guide roller 301. The cross guide roller 301 adheres to the top of the lining through the anti-slip pad 302 and rotates as the lining is conveyed. It contacts the pressure block 303, causing the pressure block 303 to contract under force. The feedback is sent to the controller 204 through the wire, which drives the second pair of pusher components 4 to push the qualified lining into the left discharge port 102 for discharge. When the lining thickness is less than the qualified standard, the lining does not contact the bonding roller 2055 and the cross guide roller 301 when it passes through the bonding roller 2055 and the cross guide roller 301. This type of lining is directly conveyed to the end of the intermittent conveyor belt 101 for screening.

[0033] In addition, it should be noted that the intermittent conveyor belt 101, electric push rod 2011, controller 204, infrared receiver 202 and infrared transmitter 206 are all existing technologies, and their internal working principles and operation procedures will not be described in detail here.

[0034] The working process of this utility model is as follows: First, the intermittent conveyor belt 101 carries the liner to be tested under the measuring component 205 for testing. When the liner thickness is qualified, the top of the liner is attached to the bonding roller 2055, the bottom of the liner passes the measuring component 205, and then is conveyed to the bottom of the cross guide roller 301. The cross guide roller 301 is attached to the top of the liner by the anti-slip pad 302 and rotates as the liner is conveyed, contacting the pressure block 303 and causing the pressure block 303 to contract under force. The feedback is sent to the controller 204 through the wire, which drives the pushing component 4 to push the qualified liner into the left discharge port 102 for discharge. When the liner thickness is less than the qualified standard, the liner does not contact the bonding roller 2055 and the cross guide roller 301 when passing through them. This type of liner is directly conveyed to the intermittent conveyor belt 101. At the end of the conveyor belt 101, the defective liner is screened out. When the thickness of the liner exceeds the qualified standard, the return spring 2052, through its own elasticity, causes the telescopic rod 2051 to contract under force, pulling the connecting frame 2053 to drive the bonding roller 2055 to rise, so that the bonding roller 2055 is in contact with the top of the liner. When the connecting frame 2053 rises, it causes the shielding frame 2054 to be sleeved on the outside of the infrared transmitter 206 to block the infrared emitting end, so that the infrared receiver 202 can give feedback to the controller 204 through the wire, driving the pusher assembly 201. The electric push rod 2011 pushes the defective liner to the discharge port 102 through the pusher frame 2012. The guide wheel 1021 assists the defective liner to slide smoothly down the discharge slope 103 for discharge, so that the defective liner leaves the intermittent conveyor belt 101, making it easy for workers to recycle and process.

[0035] The entire operation process is simple and convenient. Compared with existing liner inspection devices, this utility model can improve the accuracy and efficiency of liner screening and enhance its overall practicality through design.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
