[0028] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] The term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present application. In the description of the present application, it should be understood that the terms "upper," "lower," "top," "bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present application.

[0030] The following describes a positioning device for flexible products provided in an embodiment of the present application in conjunction with the accompanying drawings, wherein the positioning device of the present application is particularly suitable for flexible long strip products.

[0031] See Figure 1-Figure 5 , the present application provides a positioning device for a flexible product, the positioning device comprising a mounting plate 50, a base 10, a positioning member 21, an adsorption mechanism and a plurality of floating mechanisms 40;

[0032] At least one base 10 is provided on the mounting plate 50, and a positioning member 21 and an adsorption mechanism are provided on the base 10. The base 10 has a bearing position for bearing a target flexible product. The positioning member 21 protrudes from the base 10 and can position the target flexible product at the bearing position. The adsorption mechanism can be adsorbed and connected with the target flexible product fixed on the bearing position.

[0033] Multiple floating mechanisms 40 are in transmission connection with the base 10 and can move in coordination to drive at least the supporting portion of the base 10 to reciprocate toward or away from the mounting plate 50. By first positioning the target flexible product and then adsorbing it, the multiple floating mechanisms 40 simultaneously lift the target flexible product, thereby improving the accuracy of the target flexible product's positioning.

[0034] It is understandable that flexible products are often used in electronic equipment, automotive industry, manufacturing industry and other fields. When mounting flexible products, since some flexible products are long, traditional positioning devices are ineffective and manual handling of flexible products is required. When moving and mounting the products, flexible products are prone to wrinkles and poor processing effects.

[0035] In one embodiment, the material of the target flexible product is PI polyimide, and the length of the flexible product is 2398 mm and the thickness is 0.37 mm.

[0036] Specifically, a base 10 or multiple bases 10 are provided on the mounting plate 50, and a positioning mechanism 20, an adsorption mechanism and a floating mechanism 40 are provided on the base 10. The positioning mechanism 20 is used to fix the target flexible product in the bearing position, the adsorption mechanism is used to directly contact the target flexible product and generate negative pressure so that the target flexible product fits the bearing position set on the base 10, and the floating mechanism 40 is used to drive the target flexible product to move and thereby change the height difference between the base 10 and the mounting plate 50.

[0037] Optionally, the positioning member 21 may be a positioning pin or a positioning bump, etc.

[0038] Specifically, the positioning device also includes a control system, which is used to issue control instructions to the positioning mechanism 20, the adsorption mechanism and the floating mechanism 40, thereby adjusting the operating parameters of the positioning mechanism 20, the adsorption mechanism and the floating mechanism 40, thereby ensuring the precise positioning of the flexible product and the coordinated implementation of the adsorption process.

[0039] Specifically, the base 10 places the target flexible product on the load-bearing position at a preset position on the mounting plate 50, drives the positioning mechanism 20, and the positioning member 21 accurately positions the target flexible product on the load-bearing position; drives the adsorption mechanism, and the adsorption mechanism further strengthens the force between the target flexible product and the load-bearing position; drives the floating mechanism 40, and the base 10 moves in a direction close to the mounting plate 50, thereby realizing the processing of the target flexible product in different processes.

[0040] Furthermore, the floating mechanism 40 includes an elastic member and a guide assembly, and the guide assembly is elastically connected to the base 10 via the elastic member;

[0041] When the elastic member is compressed, the bearing portion of the base 10 can move from its initial position toward the mounting plate 50. When the elastic member is released, the bearing portion of the base 10 can return to its initial position away from the mounting plate 50. In this way, the elastic connection between the guide assembly and the base 10 enables reciprocating movement of the base 10 within a predetermined range. The floating mechanism 40 automatically returns to its initial position upon release of the driving force, reducing manual intervention and improving the stability of the positioning device.

[0042] Specifically, the guide assembly includes a guide rod and a guide rod mounting seat, the elastic member includes a compression spring, the guide assembly is used to control the motion trajectory of the base 10, the guide rod can drive the base 10 to move along a straight line, the elastic member is used to provide elastic force, and the elastic member is installed between the base 10 and the guide assembly.

[0043] Specifically, when the elastic member is compressed, the guide assembly can drive the bearing position of the base 10 to move from the initial position in the direction close to the mounting plate 50 until it moves to the target position, wherein, when the base 10 is in the initial position, there is a preset height difference between the base 10 and the mounting plate 50, and when the base 10 is in the target position, the base 10 is flush with the mounting plate 50, eliminating the preset height difference; when the elastic member is released, the guide assembly can restore the bearing position of the base 10 to the initial position in the direction away from the mounting plate 50.

[0044] Furthermore, the positioning device also includes a positioning member mounting base, a sliding assembly, and a drive assembly. The positioning member 21 is fixedly connected to the positioning member mounting base, the drive assembly is in transmission connection with the sliding assembly, and the sliding assembly is fixedly connected to the positioning member mounting base. Thus, the positioning pin mounting base is slidably connected to the drive assembly via the sliding assembly, allowing the positioning pin to move freely within a preset range, thereby enabling rapid adjustment of positioning to suit different operational requirements.

[0045] Specifically, the positioning member 21 is fixedly connected to the positioning member mounting base via fasteners or welding. The positioning member mounting base is capable of moving under the influence of the sliding assembly, thereby adapting to the size and shape of different flexible products. The connection between the sliding assembly and the positioning member mounting base uses fasteners or snaps to ensure the stability of the positioning member 21 during sliding. The sliding assembly includes a slide rail and a slider, ensuring that the positioning member mounting base can move precisely along a predetermined path.

[0046] Optionally, the slide rail can be a linear guide rail or a ball guide rail to reduce friction and ensure smooth movement. The positioning member mounting seat is connected to the base 10 through a sliding assembly to achieve linear sliding of the positioning member 21. In this embodiment, the driving assembly adopts a cylinder; in another embodiment, the driving assembly adopts an electric push rod, a stepper motor or a servo motor.

[0047] Specifically, the driving assembly is started, driving the slider of the sliding assembly to move on the slide rail, and the slider is fixedly connected to the positioning member mounting seat, thereby driving the positioning member 21 to move.

[0048] Specifically, the positioning member 21 is clearance-fitted with the positioning hole on the target flexible product. This provides a clear insertion path for the positioning pin, ensuring accurate alignment of the target product during assembly or processing, thereby improving overall positioning accuracy. The clearance fit between the two allows for a certain amount of movement and error, allowing the target product to adapt to minor deviations in production during assembly, simplifying assembly operations.

[0049] In this embodiment, the positioning hole on the target flexible product has a diameter of 3.5 mm, the outer diameter of the positioning pin is less than or equal to 3.5 mm, and the clearance between the target flexible product and the positioning pin is in the range of 0.01-0.05 mm.

[0050] In one possible implementation, the number of positioning pins is greater than or equal to the number of positioning holes on the target flexible product; in another possible implementation, the number of positioning pins is less than the number of positioning holes on the target flexible product.

[0051] In one embodiment, the length of the bearing position is greater than or equal to a preset length, which is 2.4-2.7 m. The base 10 is combined with the flexible long product to improve the overall stability and production efficiency of the positioning device.

[0052] Specifically, the length of the support position is consistent with the length of the target flexible product. In the embodiment of this specification, the length of the support position is greater than 2.4m, which is greater than the length of the target product.

[0053] In another embodiment, the length of the bearing position is greater than or equal to a preset length, and the preset length is 1.2-1.4 m.

[0054] In one embodiment, the positioning device includes a plurality of positioning members 21, and the plurality of positioning members 21 are evenly distributed along the length direction of the bearing position. The plurality of evenly distributed positioning pins can enhance the overall stability of the base 10 and improve the positioning accuracy.

[0055] Specifically, the intervals between adjacent positioning members 21 are equal, and a positioning member 21 mounting hole is provided on the base 10. The positioning member 21 mounting hole is clearance-matched with the positioning member 21. After the positioning mechanism 20 is started, the positioning member 21 is protruded relative to the positioning member 21 mounting hole; after the positioning mechanism 20 is closed, the positioning member 21 is flush or sunken relative to the positioning member 21 mounting hole.

[0056] In one embodiment, the spacing between adjacent positioning members 21 is 30 mm to 60 mm. In this way, the positioning pins can effectively position the target product during assembly and processing, reduce errors caused by distances that are too close or too far, and enhance precision.

[0057] In another embodiment, the arrangement of the positioning members 21 includes dense arrangement and sparse arrangement. For the load-bearing parts of the flexible product and areas with high precision requirements, a dense arrangement is adopted, and the spacing between adjacent positioning members 21 is 30mm-45mm; for areas that do not require high-precision positioning, a sparse arrangement is adopted to increase the spacing.

[0058] In a possible implementation manner, the spacing distance between adjacent positioning members 21 is 40 mm-50 mm.

[0059] Furthermore, the adsorption mechanism includes a suction cup 31, which is adjacent to the positioning member 21. The suction cup 31 and the positioning pin are adjacent to each other to ensure that the target product is in close contact with the suction cup 31 during positioning, thereby enhancing the adsorption effect and ensuring that the product does not fall off during processing or transportation.

[0060] Specifically, the suction cup 31 is arranged on the central axis of the bearing position of the base 10 along the length direction, and the spacing between adjacent suction cups 31 and positioning members 21 is equal, and the spacing between the suction cup 31 and the positioning member 21 is 5mm-10mm.

[0061] Specifically, the adsorption mechanism also includes a quick connector, which is used to quickly connect and disconnect the suction cup 31 with the air source or vacuum system. The adsorption mechanism connects multiple suction cups 31 in series or in parallel through the air source pipeline. After the suction cup 31 is connected to the air source through the quick connector, it provides sufficient adsorption force to fix the flexible product on the bearing position.

[0062] Specifically, a plurality of bases 10 are provided on the mounting plate 50, and the plurality of bases 10 are arranged in parallel. In this way, the parallel arrangement of the bases 10 can effectively utilize the space of the mounting plate 50, allowing the plurality of bases 10 to work in parallel within a limited area, thereby improving the utilization efficiency of the mounting plate 50.

[0063] Specifically, the present application is provided with a plurality of bases 10 , the lengths of the plurality of bases 10 are consistent, and the intervals between adjacent bases 10 are consistent.

[0064] In a possible implementation, when the length of the flexible product is greater than the length of the base 10 , a plurality of bases 10 are placed along the direction in which the length of the flexible product extends.

[0065] The present application also provides a mounting device, comprising a positioning device and a bonding device as described in any of the above embodiments. The bonding device is configured to carry a product to be bonded that matches a target flexible product. The bonding device and the positioning device are capable of relative movement until the target flexible product, lifted by the movement of the plurality of floating mechanisms 40, is bonded to the product to be bonded. The relative movement between the bonding device and the positioning device ensures precise alignment of the target flexible product and the product to be bonded during bonding, thereby reducing errors during the bonding process and ensuring product quality.

[0066] In one possible embodiment, the laminating device moves in a direction close to the supporting position so that the product to be laminarized is laminated with the target flexible product; in another possible embodiment, the supporting position moves in a direction close to the laminating device so that the product to be laminarized is laminated with the target flexible product.

[0067] Specifically, in the embodiment of the present application, the product to be bonded is an aluminum plate, and the target flexible product is bonded to the aluminum plate.

[0068] Furthermore, the mounting equipment also includes a film tearing mechanism, which is a mechanical device for tearing off the protective film from the surface of the product. The film tearing mechanism includes a film clamping device, a film pulling roller, a guide system, a robotic arm and a film recovery device.

[0069] The following describes the working process of the positioning device in the embodiment of the present application in combination with specific application scenarios, as follows:

[0070] First, the target flexible product is placed on the supporting position of the base 10, and the positioning cylinder in the positioning mechanism 20 drives the positioning pin to move in the direction close to the mounting plate 50, and the positioning pin is loosely matched with the positioning hole of the target flexible product;

[0071] Then, the adsorption mechanism is driven, and the suction cup 31 of the adsorption mechanism adsorbs the target flexible product. When the air pressure of the adsorption mechanism reaches 60 kPa, the multiple floating mechanisms 40 simultaneously lift the bearing position in the direction close to the mounting plate 50 to drive the target flexible product to move;

[0072] Finally, the film tearing mechanism tears off the centrifugal film of the target flexible product, and the laminating device moves in a direction close to the carrying position to laminate the product to be laminated with the target flexible product.
