Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a flipping mechanism compatible with products of different specifications and sizes. Background Technology

[0002] The most important safety system in a car is the braking system, and all braking components are safety parts. Brake pads are one of the most important components in the entire braking system, directly affecting its reliability. Therefore, brake pads are the most critical safety component, and the effectiveness of braking depends entirely on them.

[0003] In the production process of automotive brake pads, it is often necessary to flip the brake pads to facilitate subsequent operations. For example, during brake pad manufacturing, the brake pads need to be flat-ground and grooved, then flipped 180° before being output to the next station for painting. Another example is the inspection of brake pads after manufacturing, which also frequently involves flipping. However, existing brake pad flipping devices are generally only used for flipping brake pads of specific specifications, resulting in limited applicability and complex structures. For instance, the automatic brake pad flipping machine disclosed in patent publication number CN206842443U uses a flipping cylinder to flip the brake pads, but it can only flip brake pads of specific specifications and sizes, limiting its applicability and practicality. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a flipping mechanism compatible with products of different specifications and sizes, comprising a base plate, the base plate being connected to a translation drive source for driving its horizontal forward and backward movement, two support plates symmetrically arranged front and back on the top of the base plate, a rotating shaft arranged horizontally front and back between the two support plates, one end of the rotating shaft being connected to a flipping drive source for driving its rotation, a flipping plate being connected to the side of the rotating shaft, a fixing plate being mounted on the flipping plate, a mounting plate being connected to the side of the fixing plate near the flipping plate, two replaceable electromagnets being provided on the side of the mounting plate away from the fixing plate, the electromagnets being connected to a PLC control system, an elastic buffer assembly being provided between the fixing plate and the mounting plate, a sensing plate being provided on the end of the rotating shaft away from the flipping drive source, two photoelectric sensors being provided on one of the two support plates near the sensing plate, and the two photoelectric sensors being symmetrically arranged on both sides of the rotating shaft.

[0006] Further optimization involves having four elastic buffer components arranged in a rectangular array, ensuring greater stability of the mounting plate and improved buffering performance.

[0007] In a further optimization, the elastic buffer assembly includes a guide rod, on which a linear bearing mounted on a fixed plate is sleeved. The guide rod is fixedly connected to the mounting plate, and a spring is provided between the fixed plate and the mounting plate, with the spring sleeved on the guide rod. The guide rod is used for connection, the linear bearing is used for guiding the movement of the guide rod, and the spring provides buffering performance.

[0008] Further optimization involves providing a first rectangular mounting groove on the side of the mounting plate away from the fixed plate. A second rectangular mounting groove is located in the center of the bottom of the first mounting groove. Two symmetrically arranged second connecting holes are located in the center of the second mounting groove along its length. The first mounting groove contains four first connecting holes for connecting to the guide rod. Both the first and second mounting grooves are used for the installation and positioning of the electromagnet. The second connecting holes are used for connecting the electromagnet, and the first connecting holes are used for connecting the mounting plate to the guide rod.

[0009] Further optimization involves providing a mounting hole at the center of the second mounting slot, within which a metal sensor is installed. This mounting hole is used to install the metal sensor, which is used to detect the presence and position of the product.

[0010] Further optimization involves making the second connecting hole an oblong hole, the length of which is the same as the length of the second mounting groove, facilitating the installation and position adjustment of the electromagnet.

[0011] Further optimization involves a linear module for the translation drive source, with a linear guide rail connected to the substrate on each of the left and right sides of the translation drive source, ensuring smooth and stable forward and backward movement of the substrate.

[0012] Further optimization involves a servo geared motor as the rotation drive source, which is connected to the rotating shaft via a coupling.

[0013] Further optimization includes a limiting plate on the side of the support plate furthest from the base plate on both the left and right sides, a reinforcing plate connecting the flip plate and the rotating shaft, two connecting plates symmetrically arranged front and back connecting the flip plate and the fixing plate, and a through hole for the mounting plate to avoid obstruction.

[0014] Beneficial effects: The flipping mechanism of this utility model is compatible with products of different specifications and sizes. It realizes the overall movement of the substrate and its connected flipping part structure through the translation drive source, realizes the movement of the electromagnet to the center position of the product, realizes the adsorption of products of different widths at the center position, and thus ensures the flipping of products of different widths.

[0015] The rotating shaft is driven by a flip drive source, which in turn drives the flip plate and electromagnet to flip 180°, thus flipping the product.

[0016] The structure of the first mounting slot, the second mounting slot, and the second connecting hole on the mounting plate enables the rapid installation and positioning of electromagnets of different specifications and sizes, thereby allowing the electromagnets to be adapted to attract products of different sizes, ensuring a firm attraction to the products, and making the replacement of the electromagnets simple and easy.

[0017] By setting up the elastic buffer component, the electromagnet can absorb and mitigate the impact or vibration of the product, prevent the product from being crushed and damaged, and at the same time have the functions of size compensation, automatic adjustment and self-adaptation, so that the electromagnet can be compatible with the height difference of products of different specifications.

[0018] The flipping mechanism has a clever structural design, wide applicability, and can adapt to the flipping operations of different products, making it highly practical. Attached Figure Description

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figure 1-7 As shown, a flipping mechanism compatible with products of different specifications and sizes includes a base plate 1. The base plate 1 is connected to a translation drive source 2 for driving its horizontal forward and backward movement. Two support plates 3 are symmetrically arranged on the top of the base plate 1. A rotating shaft 4 is horizontally arranged between the two support plates 3. One end of the rotating shaft 4 is connected to a flipping drive source 5 for driving its rotation. A flipping plate 6 is connected to the side of the rotating shaft 4. A fixing plate 7 is mounted on the flipping plate 6. A mounting plate 8 is connected to the side of the fixing plate 7 near the flipping plate 6. Two replaceable electromagnets 9 are provided on the side of the mounting plate 8 away from the fixing plate 7. The electromagnets 9 are connected to a PLC control system. An elastic buffer assembly 10 is provided between the fixing plate 7 and the mounting plate 8. A sensing plate 11 is provided at the end of the rotating shaft 4 away from the flipping drive source 5. Two photoelectric sensors 12 are provided on one of the two support plates 3 near the sensing plate 11. The two photoelectric sensors 12 are symmetrically arranged on both sides of the rotating shaft 4.

[0029] In this application, the flipping mechanism is used for flipping automotive brake pads on a production line, realizing automatic flipping of the product (automotive brake pads), and can adapt to flipping operations of products with different widths. Specifically, the flipping mechanism includes a base plate 1, a translation drive source 2, a support plate 3, a rotating shaft 4, a flipping drive source 5, a flipping plate 6, a fixing plate 7, a mounting plate 8, an electromagnet 9, an elastic buffer assembly 10, a sensing sheet 11, and a photoelectric sensor 12. The base plate 1 is used to mount the flipping components of the mechanism. The translation drive source 2 drives the base plate 1 to move horizontally back and forth, allowing for position adjustment of the flipping components. This enables the electromagnet 9 to attract the center position of products of different widths, ensuring stable attraction during the flipping process and adapting to flipping of products of different specifications. The support plate 3 supports the rotating shaft 4 and mounts the flipping drive source 5 and the photoelectric sensor 12. The flipping drive source 5 drives the rotating shaft 4 to flip, ultimately flipping the product 180°. The rotating shaft 4 drives the flipping plate 6 to rotate, enabling the mounting of the fixing plate 7, which in turn mounts the mounting plate 8. The mounting plate 8 is used for... The installation of magnet 9 is adaptable to different specifications of electromagnet 9, accommodating the adsorption of products of varying widths. Electromagnet 9 is connected to a PLC control system, which controls the current flow of electromagnet 9, enabling electromagnetic control of its presence or absence for easy product adsorption or release. The elastic buffer assembly 10 provides elastic buffering performance to the mounting plate 8, ensuring cushioning when electromagnet 9 presses down to adsorb products. It absorbs and mitigates the impact or vibration of electromagnet 9 on products, preventing damage caused by pressure. It also features size compensation, automatic adjustment, and self-adaptation, allowing electromagnet 9 to accommodate height differences of products of varying specifications. The sensing plate 11 works in conjunction with the photoelectric sensor 12 to precisely control the rotation angle of the rotating shaft 4. The photoelectric sensor 12 transmits the positioning information of the sensing plate 11 to the PLC control system, which then controls the rotation and stop of the flipping drive source 5, ultimately achieving product flipping.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment of this application, there are four elastic buffer components 10 arranged in a rectangular array. The arrangement of the four elastic buffer components 10 ensures that the vibration of the mounting plate 8 is smaller and more stable when its elastic position changes, and that it can absorb greater impact force, ensuring that the product is not damaged.

[0031] like Figure 4As shown, the elastic buffer assembly 10 further includes a guide rod 101, on which a linear bearing 102 mounted on a fixed plate 7 is sleeved. The guide rod 101 is fixedly connected to the mounting plate 8. A spring 103 is provided between the fixed plate 7 and the mounting plate 8, and the spring 103 is sleeved on the guide rod 101. The guide rod 101 connects the fixed plate 7 and the mounting plate 8, the linear bearing 102 guides the guide rod 101, ensuring smoother and more stable movement with low friction, and the spring 103 provides buffering, elastic reset, and elastic compression, ensuring buffering of the electromagnet 9 during downward pressure and compatibility with height differences between products of different specifications.

[0032] For example, 5. Figure 6 As shown, based on the above scheme, in another embodiment of this application, the side of the mounting plate 8 away from the fixing plate 7 is provided with a first mounting groove 81 of rectangular structure, the bottom of the first mounting groove 81 is provided with a second mounting groove 83 of rectangular structure, the middle of the second mounting groove 83 is provided with two symmetrically arranged second connecting holes 84 along its length direction, and the first mounting groove 81 is provided with four first connecting holes 82 for connecting with the guide rod 101.

[0033] In this embodiment, the mounting plate 8 has two mounting slots, namely a first mounting slot 81 and a second mounting slot 83. Both the first mounting slot 81 and the second mounting slot 83 are arranged horizontally, with the second mounting slot 83 located at the bottom of the first mounting slot 81. Both are used for mounting the electromagnet 9 and can accommodate electromagnets 9 of different sizes, providing a limiting effect on the installation of the electromagnet 9. By installing electromagnets 9 of different sizes, it can accommodate the adsorption and flipping of products of different sizes. Specifically, the first mounting slot 81 can accommodate large-sized electromagnets 9, while the second mounting slot 83 can accommodate small-sized electromagnets 9. The second connecting hole 84 is used for connecting and fixing the electromagnet 9; a bolt passing through the second connecting hole 84 connects it to the electromagnet 9. The first connecting hole 82 is used to connect with the guide rod 101 of the elastic buffer assembly 10, realizing the connection between the elastic buffer assembly 10 and the mounting plate 8.

[0034] Furthermore, a mounting hole 85 is provided at the center of the second mounting slot 83, and a metal sensor 13 is installed in the mounting hole 85. The mounting hole 85 facilitates the installation of the metal sensor 13, which can detect the presence or absence of the product and ensure that the electromagnet can move to the center position of the corresponding product, thus ensuring accurate adsorption and flipping of the product.

[0035] Furthermore, the second connecting hole 84 is an oblong hole, the length of which is the same as the length of the second mounting groove 83. The oblong hole structure of the second connecting hole 84 facilitates the position adjustment of the bolt-connected electromagnet 9, ensuring the installation of electromagnets 9 of different specifications and sizes. At the same time, it facilitates the adjustment of the distance between the two electromagnets 9, so that the electromagnets 9 can be adapted to attract products of different lengths.

[0036] like Figure 1-3 and Figure 7 As shown, in another embodiment of this application, the translation drive source 2 is a linear module, and a linear guide rail 15 connected to the substrate 1 is provided on each of the left and right sides of the translation drive source 2. The translation drive source 2 uses a linear module, which provides more precise movement, higher stability, and faster response speed, enabling precise and rapid adjustment of the front and rear positions of the electromagnet 9, allowing it to quickly move to the center position of products of different widths. The linear guide rails 15 ensure smooth, stable, and precise movement of the substrate 1.

[0037] like Figure 3 As shown, in another embodiment of this application, the flipping drive source 5 is a servo geared motor, and the flipping drive source 5 is connected to the rotating shaft 4 via a coupling. The flipping drive source adopts a servo geared motor, which is a rotary drive device composed of a servo motor and a reducer. It has the advantages of high torque output, precise positioning, wide speed range, smooth operation, energy saving and high efficiency, and can ensure smooth and stable flipping of the product. The flipping drive source 5 is connected to the rotating shaft 4 by a coupling, which has the effects of compensating for displacement, buffering vibration and protecting the flipping drive source 5.

[0038] like Figure 2 As shown, in one embodiment of this application, a limiting plate 14 is provided on the side of the support plate 3 that is far away from the base plate 1 on the left and right sides. A reinforcing plate 16 is connected between the flip plate 6 and the rotating shaft 4. Two connecting plates 17 are symmetrically arranged front and back between the flip plate 6 and the fixing plate 7. The flip plate 6 is provided with a through hole for the mounting plate 8 to avoid.

[0039] In this embodiment, the limiting plate 14 is used to limit the flipping of the flipping plate 6, while also providing protection and connecting the two support plates 3 to ensure the stability of the flipping structure. The reinforcing plate 16 is used to improve the connection between the flipping plate 6 and the rotating shaft 4. The connecting plate 17 is used to connect the fixing plate 7 and the flipping plate 6, thereby fixing the position of the fixing plate 7 relative to the flipping plate 6. The flipping plate 6 is provided with through holes to facilitate the installation of the mounting plate 8 and to prevent interference when the mounting plate 8 is relatively displaced relative to the fixing plate 7.

[0040] In this application, the working principle of the flipping mechanism is as follows: First, the translation drive source 2 drives the base plate 1 to move back and forth, adjusting the relative position of the electromagnet 9 so that it corresponds to the center position of the product conveyed on the production line; then, the flipping drive source 5 drives the rotating shaft 4 to rotate, causing the flipping plate 6 to flip to the right, flipping the electromagnet 9 installed on the mounting plate 8 to the top of the product. After the metal sensor 13 detects the product, the PLC control system energizes the electromagnet 9, and the electromagnet 9 attracts the product; then, the flipping drive source 5 drives the rotating shaft 4 to rotate 180° to the left, causing the flipping plate 6 to flip 180° to the left, flipping the product 180°; finally, the conveying structure catches the flipped product, and at the same time, the PLC control system de-energizes the electromagnet 9, so that the electromagnet 9 no longer attracts the product, completing the product flipping.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
