Description

Technical Field

[0001] This utility model relates to the field of assembly and processing equipment technology, specifically to a secondary curing device for an assembly machine. Background Technology

[0002] Assembly machines are devices used to automatically assemble two or more components. For some components that require adhesive bonding, the adhesive needs to be cured after assembly to improve bond strength and reliability. The curing method depends on the type of adhesive. Common curing methods include photocuring, thermocuring, and room temperature curing. Photocuring and thermocuring rely on curing equipment, which is typically located at the rear of the assembly station. Components are assembled at the assembly station and then enter the curing equipment for curing. However, this curing method has problems: the curing time of the adhesive is much longer than the component assembly time, leading to component accumulation inside the curing equipment. Increasing the size of the curing equipment would also hinder its layout. Secondly, the assembled components need to be moved a certain distance before entering the curing equipment, which may cause misalignment between the two assembled parts, reducing installation accuracy. Therefore, existing curing equipment struggles to meet the requirements of high-efficiency, high-precision assembly. Summary of the Invention

[0003] The purpose of this invention is to provide a secondary curing device for an assembly machine, which improves curing efficiency through secondary curing to solve the problem of low curing efficiency mentioned above.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a secondary curing device for an assembly machine, the assembly machine having a curing station and an assembly station for assembling workpieces, the secondary curing device including a first curing component and a second curing component arranged at intervals, the first curing component being arranged at the assembly station for first curing the workpiece at the assembly station, and the second curing component being arranged at the curing station for second curing the workpiece at the curing station, thereby realizing two curing of the workpiece.

[0005] In one embodiment, the first curing component is disposed in a part-retrieving mechanism, which is used to pick up and place an assembled workpiece to assemble the workpiece into another workpiece.

[0006] In one embodiment, the first curing assembly includes at least two first curing lamps, each of which emits an ultraviolet light beam toward the part of the workpiece to be irradiated to cure the colloid on the workpiece for the first time, and the ultraviolet light beams of each of the first curing lamps intersect.

[0007] In one embodiment, there are two first curing lamps, and the two first curing lamps are respectively disposed on opposite sides of the part-retrieving mechanism.

[0008] In one embodiment, the assembly machine has a production line for conveying the workpiece from the assembly station to the curing station, and the second curing component includes a second curing lamp disposed above the curing station, the second curing lamp being positioned toward the curing station and used to emit ultraviolet light to cure the colloid on the workpiece for a second time.

[0009] In one embodiment, the second curing assembly further includes a lifting mechanism disposed below the production line, the lifting mechanism being disposed opposite to the second curing lamp, for lifting the workpiece located above it so that the workpiece is removed from the production line and held below the second curing lamp.

[0010] In one embodiment, the lifting mechanism includes a lifting cylinder and a lifting plate disposed at the telescopic end of the lifting cylinder. The lifting plate is located between two conveyor belts of the production line, so that the lifting plate lifts the workpiece from the middle under the action of the lifting cylinder, causing the workpiece to disengage from the conveyor belt.

[0011] In one embodiment, the second curing assembly further includes a housing, and the second curing lamp is disposed within the housing via a lifting mechanism. The lifting mechanism includes a lead screw and nut structure and a slide rail and slider structure disposed opposite to each other. The lead screw and nut structure includes a nut fixedly disposed on the upper part of the housing and a screw threadedly connected to the nut. The upper end of the screw is connected to a turntable, and the lower end of the screw is fixedly connected to the second curing lamp. The rotation of the turntable drives the second curing lamp to rise and fall. The slide rail and slider structure is disposed opposite to each other on both sides of the second curing lamp. The slide rail and slider structure is respectively connected to the second curing lamp and the housing, thereby limiting the rising and falling trajectory of the second curing lamp.

[0012] The beneficial effects of this invention are as follows: This invention divides the curing process of the colloid into two curing stages. The first curing and the second curing are achieved by a first curing component and a second curing component, respectively. Setting the first curing stage at the assembly station allows for minor curing during assembly, reducing the time the workpiece spends on the assembly line and shortening the second curing time, thus improving curing efficiency and consequently increasing the efficiency of the assembly machine. Furthermore, performing the first curing during assembly helps to fix the assembled workpiece, preventing displacement during transport and ensuring assembly accuracy, thereby guaranteeing the accuracy and pass rate of workpiece assembly.

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] See Figures 1 to 3 As shown, this utility model discloses a secondary curing device for an assembly machine. The assembly machine has an assembly station 101 for assembling workpieces and a curing station 102. The assembly machine has a production line 100 for conveying workpieces. In this embodiment, the production line 100 includes two parallel conveyor belts 103. The assembly station 101 and the curing station 102 are spaced apart along the extension direction of the conveyor belts 103. The workpieces are conveyed from the assembly station 101 to the curing station 102 by the conveyor belts 103. The secondary curing device includes a first curing component 1 and a second curing component 2 spaced apart. The first curing component 1 is disposed at the assembly station 101 for first curing the workpieces at the assembly station 1, and the second curing component 2 is disposed at the curing station 102 for second curing the workpieces at the curing station 102, thereby realizing two curing of the workpieces.

[0022] This invention divides the curing process of the colloid into two stages. The first and second curing stages are achieved by a first curing component 1 and a second curing component 2, respectively. The first curing stage is set at the assembly station 101, allowing for minor curing during assembly, reducing the time the workpiece spends on the assembly line, and shortening the second curing time, thus improving curing efficiency and consequently increasing the efficiency of the assembly machine. Furthermore, performing the first curing during assembly helps to fix the assembled workpiece, preventing displacement during transport and ensuring assembly accuracy and a high pass rate.

[0023] The first curing component 1 is disposed in a part-picking mechanism 200, which is used to pick up and place one workpiece to be assembled into another workpiece. The part-picking mechanism 200 is used to pick up and place workpieces, and its structure is specifically designed according to the structure and type of the workpiece. The specific structure of the part-picking mechanism 200 is not related to the technical problem of this utility model, and will not be described in detail here.

[0024] See Figures 3 to 4 As shown, the first curing component 1 is positioned within the picking mechanism 200 and moves with it, thus moving synchronously with the workpiece picked up by the picking mechanism 200. Regardless of the workpiece's position, the first curing component 1 ensures accurate curing of the adhesive on the workpiece. In this embodiment, the workpiece picked up by the picking mechanism 200 is a first coil, and a second coil is placed on the production line 100. Multiple second coils are arranged on a fixture plate. Each first coil is sequentially moved by the picking mechanism 200 from the fixture plate on one side of the production line 100 to each second coil on the production line 100, thereby assembling the first coil into the second coil. Since there are multiple second coils on a fixture plate, the position of the first coil may vary within a certain range. In this embodiment, the first curing component 1 is positioned within the picking mechanism 200 to ensure accurate curing of the adhesive between the assembled first and second coils. In other embodiments, the first curing component 1 may also be located at other locations near the assembly station 101, such as on one side of the assembly line, and move according to the location of the workpiece being assembled. This installation method requires an additional drive mechanism to drive the curing lamp of the first curing component to move to the location of the workpiece being assembled, compared to setting it in the pick-up mechanism 200.

[0025] See Figure 5As shown, the first curing component 1 includes two first curing lamps 11, which are respectively arranged on opposite sides of the part-taking mechanism 200. Each first curing lamp 11 emits an ultraviolet beam towards the part of the workpiece to be irradiated to cure the colloid on the workpiece for the first time. That is, the two first curing lamps 11 irradiate the workpiece from opposite sides, thereby covering the colloid as much as possible. Since the two first curing lamps 11 are arranged on opposite sides of the part-taking mechanism 200, the ultraviolet beams emitted by the two first curing lamps 11 intersect, which can fully irradiate the workpiece located between the two first curing lamps 11, ensuring the reliability of curing.

[0026] In this embodiment, there are two first curing lamps 11. In other embodiments, there may be more than two first curing lamps 11, such as three or four, depending on the extent of the colloid to be cured and the irradiation range of the first curing lamps 11.

[0027] See Figure 4 , Figure 6 and Figure 7 As shown, the second curing component 2 includes a second curing lamp 21 disposed above the curing station 102. The second curing lamp 21 is positioned towards the curing station 102 and is used to emit ultraviolet light to cure the colloid on the workpiece for the second time. In this embodiment, the second curing lamp 21 is disposed above the curing station 102, enabling batch curing of multiple workpieces at once, which is suitable for situations where multiple assembled workpieces are placed on a tooling plate in this embodiment. Furthermore, since the second curing lamp 21 cures workpieces in batches, it can extend the irradiation time compared to the first curing lamp 11, allowing the colloid on the workpiece to fully cure.

[0028] To ensure the workpiece and the second curing lamp 21 remain relatively fixed in the conveying direction of the production line 100 during the second curing process and to sufficiently extend the irradiation time, the second curing assembly 2 also includes a lifting mechanism 22 disposed below the production line 100. The lifting mechanism 22 is disposed opposite to the second curing lamp 21 and is used to lift the workpiece located above it, thereby removing the workpiece from the production line 100 and holding it below the second curing lamp 21. More specifically, the lifting mechanism 22 indirectly lifts the workpiece located on the tooling plate by lifting the tooling plate, thereby removing the tooling plate and the workpiece on it from the production line 100 to maintain the relative fixation of the workpiece and the second curing lamp 21 in the conveying direction of the production line 100.

[0029] The lifting mechanism 22 includes a lifting cylinder 221 and a lifting plate 222 disposed at the telescopic end of the lifting cylinder 221. The lifting plate 222 is located between the two conveyor belts of the production line 100. Under the action of the lifting cylinder 221, the lifting plate 222 lifts the fixture plate from the middle, causing the fixture plate and the workpiece on it to detach from the conveyor belt 103. In other embodiments, the lifting mechanism 222 indirectly lifts the workpiece by lifting the fixture plate, and indirectly detaches the workpiece from the conveyor belt 103. In other embodiments, the lifting mechanism 22 can also be a rack and pinion mechanism, with the gear connected to a lifting motor and the rack used for lifting and lowering to lift the fixture plate and the workpiece.

[0030] The second curing component 2 also includes a housing 23, which prevents ultraviolet light leakage. The second curing lamp 21 is installed inside the housing 23 via a lifting mechanism 24. The lifting mechanism 24 includes a screw and nut structure and a slide rail and slider structure arranged opposite to each other. The screw and nut structure includes a nut 241 fixedly installed on the upper part of the housing 23 and a screw 242 threadedly connected to the nut 241. The upper end of the screw 242 is connected to a turntable 243, and the lower end of the screw 242 is fixedly connected to the second curing lamp 21. The second curing lamp 21 is driven to rise and fall by rotating the turntable 243. In this embodiment, the turntable 243 is provided with an operating handle, which can be manually rotated. In other embodiments, the turntable 243 can also be connected to a motor to rotate electrically, thereby electrically controlling the rise and fall of the second curing lamp 21. The slide rail and slider structure consists of two sets, arranged opposite each other on both sides of the second curing lamp 21. Each slide rail and slider structure includes a slider 244 connected to the housing 23 and a slide rail 245 connected to the second curing lamp 21. The relative sliding of the slide rail and slider restricts the lifting trajectory of the second curing lamp 21. More specifically, the lower end of the screw 242 is indirectly fixedly connected to the second curing lamp 21 by being fixedly connected to a mounting bracket 210. The second curing lamp 21 is housed within the mounting bracket 210 and rises and falls synchronously with the lifting and lowering of the mounting bracket 210. The slide rail 245 is also indirectly fixedly connected to the second curing lamp 21 by being fixedly connected to a mounting bracket 210.

[0031] In this embodiment, the curing is photocuring, and both the first curing lamp 11 and the second curing lamp emit ultraviolet light. In other embodiments, the curing method can also be thermal curing, using a hot air structure instead of the first and second curing lamps.

[0032] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that all changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
