Description

Technical Field

[0001] This invention relates to the field of frame fixture technology, and more specifically to a reflow fixture assembly machine. Background Technology

[0002] Thin boards made of flexible substrates are crucial components in the 3C electronics industry. Due to their lack of rigidity, thin boards are easily bent, deformed, or broken. Therefore, during the processing of thin boards, they must be placed in a double-plate fixture. The rigid structure of the double-plate fixture is used to protect the thin boards from deformation and breakage during transportation and processing. Figure 1 The diagram shows the structure of a double-plate fixture. This fixture consists of an upper plate and a lower plate, connected by simple clips. During reflow assembly, thin sheet metal parts need to be inserted into the fixture. The simplest method is to manually pry open the upper plate to separate the clips between the upper and lower plates, and then manually place the thin sheet metal part onto the lower plate. The separated upper and lower plates are then reassembled before unloading. While manual operation is extremely simple and effective, it suffers from inconsistencies in procedures, low efficiency, and unstable process quality. Therefore, manual operation cannot meet the demands of highly competitive industries.

[0003] In addition, in the mass production of sheet metal processing, double-plate jigs need to be continuously fed in from the outside at the feeding end to insert thin sheet metal; and at the receiving end, the double-plate jigs that have removed the thin sheet metal need to be recycled and put back into the feeding end. Therefore, manual recycling and re-input is not in line with the competitive model of mass production. Summary of the Invention

[0014] The fixture transfer and assembly mechanism includes a fixture assembly lateral movement drive mechanism mounted on the frame, a fixture assembly lifting drive mechanism mounted on the output end of the fixture assembly lateral movement drive mechanism, a fixture assembly mounting base mounted on the output end of the fixture assembly lifting drive mechanism, a fixture assembly clamping assembly mounted on the fixture assembly mounting base, and several fixture assembly suction cups. The suction cups are used to pick up the upper plate, and the fixture assembly clamping assembly is used to clamp and support the lower plate.

[0015] The fixture feeding and conveying mechanism includes a feeding conveyor belt mounted on the frame and a detection device disposed above the feeding conveyor belt.

[0016] This invention also discloses a reflow assembly / disassembly method for a double-plate fixture, the method comprising the following steps:

In use, the double-plate fixture is loaded via the fixture loading mechanism. The fixture transfer and assembly mechanism removes the double-plate fixture and places it at one end of the fixture unloading and conveying mechanism. Subsequently, the fixture transfer and assembly mechanism grasps the upper plate of the fixture, separating it from the lower plate. The plate loading and transfer mechanism then loads a thin plate from the outside and places it on the lower plate of the fixture. The fixture transfer and assembly mechanism then reassembles the upper plate onto the lower plate to form the double-plate fixture. Finally, the fixture unloading and conveying mechanism unloads the double-plate fixture. Because this invention can automatically assemble thin plates back into the double-plate fixture and automatically unload and reflow the double-plate fixture, this device can completely replace manual operation, reducing labor costs and improving process efficiency.

[0040] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0042] Furthermore, the terms "assembly" and "loading" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "assembly" or "loading" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] Thin boards made of flexible substrates are crucial components in the 3C electronics industry. Due to their lack of rigidity, thin boards are easily bent, deformed, or broken. Therefore, during the processing of thin boards, they must be placed in a double-plate fixture. The rigid structure of the double-plate fixture is used to protect the thin boards from deformation and breakage during transportation and processing. Figure 1 The diagram shows the structure of a double-plate fixture. This fixture consists of an upper plate and a lower plate, connected by simple clips. During reflow assembly, thin sheet metal parts need to be inserted into the fixture. The simplest method is to manually pry open the upper plate to separate the clips between the upper and lower plates, and then manually place the thin sheet metal part onto the lower plate. The separated upper and lower plates are then reassembled before unloading. While manual operation is extremely simple and effective, it suffers from inconsistencies in procedures, low efficiency, and unstable process quality. Therefore, manual operation cannot meet the demands of highly competitive industries.

[0044] In addition, in the mass production of sheet metal processing, double-plate jigs need to be continuously fed in from the outside at the feeding end to insert thin sheet metal; and at the receiving end, the double-plate jigs that have removed the thin sheet metal need to be recycled and put back into the feeding end. Therefore, manual recycling and re-input is not in line with the competitive model of mass production.

[0045] To address the aforementioned problems, this embodiment discloses a reflow fixture assembly machine, the structure of which is as follows: Figures 2 to 6 As shown, the combined machine includes a frame 100, a plate loading and transfer mechanism 200, a jig loading mechanism 300, a jig transfer and assembly mechanism 400 mounted on the frame 100, and a jig unloading and conveying mechanism 500. The jig loading mechanism 300 is used to load double-plate jigs, and the jig transfer and assembly mechanism 400 is used to remove the double-plate jigs from the jig loading mechanism 300 and place them at one end of the jig unloading and conveying mechanism 500, and to place the jigs located at the jig unloading and conveying mechanism 500. The upper plate 101 of the double-plate fixture with the unloading conveying mechanism 500 is removed from the lower plate 103 and the removed upper plate 101 is reinstalled back into the lower plate 103; the plate loading and transfer mechanism 200 is used to transfer the thin plate 102 from the outside to the lower plate 103 of the double-plate fixture located at one end of the fixture unloading conveying mechanism 500; the fixture unloading conveying mechanism 500 is used to fix the lower plate 103 of the double-plate fixture and unload the assembled double-plate fixture.

[0046] Specifically, the present invention provides a method for reflowing and disassembling a double-plate fixture, which includes a plate loading and transfer mechanism 200, a fixture loading mechanism 300, a fixture transfer and assembly mechanism 400, and a fixture unloading and conveying mechanism 500. In use, the double-plate fixture is loaded by the fixture loading mechanism 300, and the fixture transfer and assembly mechanism 400 removes the double-plate fixture and places it at one end of the fixture unloading and conveying mechanism 500. Subsequently, the fixture transfer and assembly mechanism 400 grasps the upper plate 101 of the fixture, separates the upper plate 101 from the lower plate 103, and the plate loading and transfer mechanism 200 loads the thin plate 102 from the outside and places it on the lower plate 103 of the fixture. Then, the fixture transfer and assembly mechanism 400 reassembles the upper plate 101 back onto the lower plate 103 to form a double-plate fixture. Finally, the fixture unloading and conveying mechanism 500 unloads the double-plate fixture. Since the present invention can automatically assemble the thin plate 102 back into the double plate fixture and can automatically unload and return the double plate fixture, the device can completely replace manual operation, which has the advantages of reducing labor costs and improving process efficiency.

[0047] Furthermore, the board loading and transfer mechanism 200 includes a board loading mechanism 202, a board conveying mechanism 205, and a board assembly mechanism 210. The board loading mechanism 202 is used to load external boards to the board loading and conveying mechanism. The board conveying mechanism 205 is used to transfer the boards to a position close to the board assembly mechanism 210. The board assembly mechanism 210 is used to transfer the boards to one end of the fixture unloading and conveying mechanism 500.

[0048] Furthermore, the plate feeding mechanism 202 includes a feeding transverse drive mechanism 203 mounted on the frame 100, a feeding lifting drive mechanism 204 mounted on the output end of the feeding transverse drive mechanism 203, a feeding mounting base 201 mounted on the output end of the feeding lifting drive mechanism 204, and a plurality of feeding suction cups 215 mounted on the feeding mounting base 201.

[0049] Furthermore, the board conveying mechanism 205 includes a first board conveying transverse mechanism 206 mounted on the frame 100, a second board conveying transverse mechanism 207 mounted on the output end of the first board conveying transverse mechanism 206, a board conveying lifting mechanism 208 mounted on the output end of the second board conveying transverse mechanism 207, and a tray 209 mounted on the output end of the board conveying lifting mechanism 208; the conveying direction of the first board conveying transverse mechanism 206 is parallel to the feeding direction of the board feeding mechanism 202, and the conveying direction of the first board conveying transverse mechanism 206 is perpendicular to the conveying direction of the second board conveying transverse mechanism 207 in the horizontal direction.

[0050] Furthermore, the panel assembly mechanism 210 includes a panel assembly transverse drive mechanism 211 mounted on the frame 100, a panel assembly lifting drive mechanism 212 mounted on the output end of the panel assembly transverse drive mechanism 211, a panel assembly mounting base 213 mounted on the output end of the panel assembly lifting drive mechanism 212, and a plurality of panel assembly suction cups 214 mounted on the mounting base.

[0051] Specifically, the structures of the sheet metal feeding mechanism 202, the sheet metal conveying mechanism 205, and the sheet metal assembly mechanism 210 can be referred to Figure 4In use, the loading transverse drive mechanism 203 and the loading lifting drive mechanism 204 drive the loading suction cups 215 to move in both horizontal and vertical directions. The multiple loading suction cups 215 pick up the thin sheet 102 from the outside and place it on the tray 209 of the sheet conveying mechanism 205. Then, the first sheet conveying transverse mechanism 206, the second sheet conveying transverse mechanism 207, and the sheet conveying lifting mechanism 208 drive the tray 209 to move in three directions: horizontal and vertical. During this process, the sheet loading mechanism 202 can return to pick up the thin sheet 102. When the tray 209 reaches the designated position, the sheet assembly transverse drive mechanism 211 and the sheet assembly lifting drive mechanism 212 are linked with the sheet assembly mounting base 213 to drive the multiple sheet assembly suction cups 214 to move in both horizontal and vertical directions, so as to transfer the thin sheet 102 to the lower plate 103 of the double-plate fixture on the fixture unloading conveying mechanism 500. Since the above processes can be carried out independently, the feeding efficiency of thin sheet 102 can be improved to a certain extent.

[0052] It should be noted that the structure and working principle of the feeding transverse drive mechanism 203, feeding lifting drive mechanism 204, feeding mounting base 201, feeding suction cup 215, first plate conveying transverse mechanism 206, second plate conveying transverse mechanism 207, plate conveying lifting mechanism 208, plate assembly transverse drive mechanism 211, plate assembly lifting drive mechanism 212, plate assembly mounting base 213, and plate assembly suction cup 214 in this embodiment are all existing technologies and will not be described in detail here.

[0053] Furthermore, the fixture loading mechanism 300 includes a fixture loading storage bin 301, a fixture loading lifting mechanism 302, a fixture loading telescopic mechanism 303, and a fixture loading support 304 mounted on the frame 100. The fixture loading storage bin 301 has an opening on one side and is mounted on the frame 100. The output end of the fixture loading lifting mechanism 302 faces the opening. The fixture loading telescopic mechanism 303 is mounted on the output end of the fixture loading lifting mechanism 302, and the fixture loading support 304 is mounted on the output end of the fixture loading telescopic mechanism 303.

[0054] Specifically, the structure of the jig feeding mechanism 300 can be referred to Figure 5In this embodiment, the empty double-plate jigs are sequentially placed in the compartment of the jig loading and storage bin 301. The jig loading lifting mechanism 302 drives the jig loading telescopic mechanism 303 to a certain position. The jig loading telescopic mechanism 303 drives the jig loading support 304 to extend into the compartment of the jig loading and storage bin 301. Then, the jig loading lifting mechanism 302 drives the jig loading telescopic mechanism 303 to rise a certain distance to lift the double-layer jig. At this time, the jig loading telescopic mechanism 303 drives the jig loading support 304 to retract, thus completing the loading and unloading of the double-plate jig. Finally, the jig loading lifting mechanism 302 drives the jig loading telescopic mechanism 303 to a certain position, so that the jig transfer and assembly mechanism 400 can clamp and remove the double-plate jig from the jig loading support 304.

[0055] It should be noted that the structure and working principle of the fixture loading lifting mechanism 302 and the fixture loading telescopic mechanism 303 in this embodiment are existing technologies and will not be described in detail here.

[0056] Furthermore, the fixture transfer and assembly mechanism 400 includes a fixture assembly lateral movement drive mechanism 401 mounted on the frame 100, a fixture assembly lifting drive mechanism 402 mounted on the output end of the fixture assembly lateral movement drive mechanism 401, a fixture assembly mounting base 403 mounted on the output end of the fixture assembly lifting drive mechanism 402, a fixture assembly clamping assembly 404 mounted on the fixture assembly mounting base 403, and a plurality of fixture assembly suction cups 405. The plurality of fixture assembly suction cups 405 are used to pick up the upper plate 101, and the fixture assembly clamping assembly 404 is used to clamp and support the lower plate 103.

[0057] Specifically, the structure of the jig transfer and assembly mechanism 400 can be referred to Figure 5 In this embodiment, the jig assembly mounting base 403 is moved horizontally and vertically by the jig assembly lateral movement drive mechanism 401 and the jig assembly lifting drive mechanism 402, thereby driving the jig assembly clamping component 404 and several jig assembly suction cups 405 mounted on the jig assembly mounting base 403 to move. The jig assembly clamping component 404 clamps the entire double-plate jig and removes it. In addition, after the double-plate jig is placed at one end of the jig unloading conveying mechanism 500, the jig assembly clamping component 404 is released, and the jig assembly suction cups 405 are adsorbed onto the upper end surface of the upper plate 101. The upper plate 101 is then removed from the lower plate 103, and after the thin plate 102 is placed, the upper plate 101 is reinstalled back onto the lower plate 103 to complete the installation of the thin plate 102.

[0058] It should be noted that the jig assembly clamping component 404 in this embodiment consists of at least two sets of cylinders and clamping fingers. The cylinders drive the clamping fingers to extend and retract, thereby pressing against both sides of the lower plate 103 to support and fix the lower plate 103. In addition, the structure and working principle of the jig assembly transverse drive mechanism 401 and the jig assembly lifting drive mechanism 402 in this embodiment are existing technologies and will not be described in detail here.

[0059] Furthermore, the fixture unloading and conveying mechanism 500 includes an unloading conveyor belt 501 mounted on the frame 100 and a detection device 502 disposed above the unloading conveyor belt 501.

[0060] Specifically, the structure of the jig feeding and conveying mechanism 500 can be based on... Figure 6 In this embodiment, since the double-plate fixture is assembled on the unloading conveyor belt 501, the fixture unloading conveyor mechanism 500 of this embodiment is preferably provided with a corresponding positioning mechanism. The positioning mechanism includes at least two partition components 503, which are respectively disposed below one end of the unloading conveyor belt 501 to abut against both sides of the double-plate fixture for positioning. In this embodiment, the partition component 503 is composed of at least a cylinder, a swing arm, and a baffle. The extension and retraction of the cylinder drives the swing arm to extend and retract, thereby driving the baffle to flip, so as to abut against both sides of the double-plate fixture for positioning.

[0061] In addition, since the rotation direction of the baffle of the aforementioned partition assembly 503 is parallel to the conveying direction of the unloading conveyor belt 501, the unloading conveying mechanism of this embodiment also includes two clamping assemblies 504, which are respectively disposed on both sides below the unloading conveyor belt 501. The clamping assembly 504 consists of at least a cylinder and a clamping arm. The extension and retraction of the cylinder drives the clamping arm to extend and retract, so as to clamp the lower plate 103 of the double plate fixture.

[0062] It should be noted that the structure and working principle of the feeding conveyor belt 501 and the detection device 502 in this embodiment are existing technologies and will not be described in detail here.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
