Description

Technical Field

[0001] This utility model relates to the field of brake pad production equipment technology, and in particular to a gripping and detection device. Background Technology

[0002] In the hot pressing production process of brake pads, after the main and auxiliary materials for production are added and spread out in the cavity of the hot press mold, the steel backing needs to be placed into the cavity and enter the hot press for hot pressing to form the finished brake pad. The pressed brake pad is then taken out from the mold cavity. Existing automated brake pad production equipment requires the use of a gripping device to pick up and put down the steel backing and the finished product.

[0003] Chinese utility model patent (CN216730821U) discloses a material handling device for brake pad production, and Chinese invention patent (CN110744858B) discloses a gripping and detection device that works in conjunction with a hot press with a mold removal mechanism. Although both can work with the hot press to handle the handling of steel backing and finished products, their overall structures are relatively complex, their operation processes are cumbersome, which affects production efficiency and results in high production and operating costs, making them difficult to promote.

[0004] Therefore, it is necessary to propose a gripping detection device to overcome the shortcomings of the existing technology. Utility Model Content

Pushing cylinders are provided on the outside of the two electromagnets in the same group, and proximity switches are provided between the two electromagnets in the same group.

[0022] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0023] like Figure 1 and Figure 2 As shown, a gripping and detection device includes a fixed plate 1, a transverse mechanism, a gripping mechanism, and a detection mechanism. The fixed plate 1 serves as the mounting base for the transverse mechanism, gripping mechanism, and detection mechanism, and also enables connection to the outside. Specifically, the transverse mechanism is mounted on the fixed plate 1, and a top plate 3 is connected to the transverse mechanism. The top plate 3 can reciprocate relative to the fixed plate 1 under the action of the transverse mechanism to achieve position switching, facilitating the picking up of steel backing and brake pad finished products. Two symmetrically distributed stiffeners 2 are installed on the upper surface of the fixed plate 1 to enhance the reliability of the connection between the fixed plate 1 and the outside. A bottom plate 4 is connected to the top plate 3, and the bottom plate 4 can float relative to the top plate 3 to eliminate the impact force during picking. The gripping mechanism and the detection mechanism are both mounted on the bottom plate 4.

[0024] like Figure 1 and Figure 2 As shown, the traversing mechanism includes a drive motor 5, linear guide rails 6, and a ball screw 7. The drive motor 5 is mounted on one end of the top surface of the fixed plate 1 via a motor bracket. Both the linear guide rails 6 and the ball screw 7 are mounted on the bottom surface of the fixed plate 1. The ball screw 7 is located between the two linear guide rails 6, and both ends of the ball screw 7 are rotatably connected to the fixed plate 1 via bearing seats. The drive motor 5 and the ball screw 7 are connected by a transmission, and the drive motor 5 drives the ball screw 7 to rotate. The transmission method is not limited to belt drive; in this embodiment, synchronous belt drive is used as an example. The drive motor 5 and the ball screw 7 are both fixedly connected to synchronous pulleys. Power is transmitted between the two synchronous pulleys through a synchronous belt. After installation, a transmission protective cover 20 is installed on the motor bracket to protect the transmission between the drive motor 5 and the ball screw 7 and prevent damage caused by collision during movement. The top plate 3 is connected to the slider of the linear guide 6 and is threadedly connected to the ball screw 7. The rotation of the ball screw 7 drives the top plate 3 to move back and forth along the linear guide 6 relative to the fixed plate 1.

[0025] like Figure 1 and Figure 2 As shown, the base plate 4 is connected to the top plate 3 via guide rods 8. Specifically, four guide rods 8 are installed on the base plate 4, symmetrically distributed in pairs. The lower ends of the guide rods 8 are connected to the base plate 4 with bolts, and the upper ends of the guide rods 8 pass upwards and slide relative to the top plate 3. A linear bearing 9 is installed at the position where the guide rod 8 passes through the top plate 3, and the guide rod 8 is connected inside the linear bearing 9. The linear bearing 9 supports and guides the guide rod 8, realizing the linear reciprocating motion of the guide rod 8. A limit block 10 is installed at the upper end of the guide rod 8 to limit the position of the base plate 4 and prevent the base plate 4 from falling off the top plate 3. A floating spring 11 is fitted on the guide rod 8 between the top plate 3 and the base plate 4. During the handling process, when the base plate 4 approaches the steel back or brake pad, the floating spring 11 can be compressed to generate displacement of the base plate 4 relative to the top plate 3, avoiding hard collisions that could damage parts and improving the service life.

[0026] like Figure 1 and Figure 2 As shown, the gripping mechanism includes several electromagnets 12, which are arranged in pairs to form multiple groups. These groups of electromagnets 12 are installed alternately on the lower surface of the base plate 4. Each group of electromagnets 12 can adsorb one steel back or one brake pad finished product. Multiple steel backs and brake pad finished products can be adsorbed simultaneously, improving production efficiency. Pushing cylinders 13 are installed on the outer side of the two electromagnets 12 in the same group. When placing the steel back or brake pad finished product, the electromagnet 12 still retains magnetic residue after being de-energized, causing the steel back or brake pad finished product to remain adsorbed on the electromagnet 12. The pushing cylinders 13 push the steel back or brake pad finished product away from the electromagnet 12. By installing two pushing cylinders 13, it is possible to avoid skew during the pushing process. A proximity switch 14 is installed between the two electromagnets 12 in the same group to detect the presence or absence of the steel back or brake pad finished product and whether it has been pushed away in a non-contact manner.

[0027] like Figure 1 and Figure 2As shown, the detection mechanism is used to detect whether the steel back is placed flat. The detection mechanism includes a detection cylinder 15, a detection plate 16, and detection springs 17. The detection cylinder 15 is mounted on a cylinder bracket 18, which is mounted on one end of the base plate 4. The detection plate 16 is connected to the output end of the detection cylinder 15. There are four detection springs 17, which are arranged in pairs to form two groups. The two groups of detection springs 17 are symmetrically installed at both ends of the detection plate 16. The lower ends of the detection springs 17 extend beyond the detection block and are flush with the detection plate. The detection springs 17 in the same group are connected to the positive and negative terminals of the power supply, respectively. Under normal circumstances, when the steel back is flat, the detection cylinder 15 extends, and the detection springs 17 move closer to the steel back. The two detection springs 17 in the same group do not contact the steel back at the same time, and there is no electrical connection between the two detection springs 17 in the same group, thus indicating that the steel back is placed normally. Under abnormal circumstances, when the steel back is not flat, the detection cylinder 15 extends, and the two detection springs 17 in the same group contact the steel back to form a circuit, thus indicating that the steel back is placed abnormally.

[0028] like Figure 1 and Figure 2 As shown, two symmetrical semi-protective covers 19 are connected to the top plate 3. After the two semi-protective covers 19 are installed, they form a protective cover with a hollow interior and an open bottom, which surrounds and protects the space between the top plate 3 and the bottom plate 4, improves the aesthetics of the appearance, and can prevent collisions.

[0029] The working principle of this utility model is as follows:

[0030] Picking and placing the steel back: The device is driven to approach the steel back. When the proximity switch 14 detects the steel back, it continues to move so that the electromagnet 12 contacts the steel back. During the contact process, the compressible floating spring 11 produces floating deformation to avoid hard contact. The electromagnet 12 is energized, attracting the steel back and moving it to the position where the steel back is placed on the hot press. The electromagnet 12 is de-energized, and at the same time, the pushing cylinder 13 extends to remove the steel back from the electromagnet 12. The steel back is placed in the mold cavity of the hot press. After moving a certain displacement, the detection cylinder 15 extends, causing the detection spring 17 to approach the placed steel back. If the detection spring 17 contacts the steel back to form a circuit, it is judged that the steel back is placed abnormally and an alarm signal is issued. If the detection spring 17 does not contact the steel back, it is judged that the steel back is placed normally and subsequent hot pressing molding operations can be performed.

[0031] Picking and placing finished brake pads: The device is driven to approach the finished brake pads. When the proximity switch 14 detects the finished brake pads, it continues to move so that the electromagnet 12 contacts the finished brake pads. During the contact process, the compressible floating spring 11 generates floating deformation to avoid hard contact. The electromagnet 12 is energized, attracting the finished brake pads and moving them to the unloading conveyor position. The electromagnet 12 is de-energized, and at the same time, the pushing cylinder 13 extends, causing the finished brake pads to detach from the electromagnet 12 and be placed on the unloading conveyor line for conveying.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
