Description

Technical Field

[0001] This invention relates to the field of automated assembly equipment for electronic products, and specifically to a fixture and method for assembling electronic paper modules (such as electronic price tags). Background Technology

[0002] With the development of the Internet of Things and new retail, devices using electronic paper display technology, such as electronic price tags, are becoming increasingly widely used. The core assembly process for these devices mainly includes: precisely flipping, folding, and pasting the electronic paper display module and the printed circuit board, and then assembling the pasted module into the middle frame.

[0003] In existing technologies, this process largely relies on manual operation, which presents the following significant problems: 1. When electronic paper display modules and circuit boards are manually pasted by touch and visual inspection, misalignment is very likely to occur, resulting in low product yield. 2. Manually pressing the module into the middle frame is labor-intensive, inefficient, and can easily cause finger fatigue and injury to the operator. 3. The entire process requires collaboration from multiple people, resulting in high labor costs.

[0004] To address the aforementioned issues, while existing technologies have mentioned the concept of automatic flipping and assembly, they lack specific technical solutions for automated fixtures that are compact, highly integrated, and capable of continuously completing multiple key assembly steps on a rotating platform.

[0005] Definitions: PCBA stands for Printed Circuit Board Assembly, which refers to a circuit board that has completed the mounting and soldering of components.

[0006] The full name of EPD module is Electronic Paper Display Module, which is a display device that uses electronic ink technology to simulate paper display. Summary of the Invention

[0007] The present invention aims to provide an assembly fixture for electronic paper devices to solve the problems of low efficiency, poor accuracy and high labor intensity of manual assembly.

[0008] (a) The technical problem to be solved This solution addresses the issue of misalignment during the bonding of electronic paper display modules to circuit boards, improving bonding accuracy and production yield. It also reduces the labor intensity of the mid-frame assembly process, enhancing automation and production efficiency. Furthermore, it reduces reliance on skilled workers, streamlines production steps, and saves on labor costs.

[0009] To integrate the feeding, hinge, and component movement processes into a single machine, the applicant proposes an electronic paper device assembly fixture for assembling electronic paper modules. The electronic paper module includes a circuit board, a mid-frame, and an electronic paper display module, comprising a rotating disk and an A component. The A component is mounted on the rotating disk and includes at least one set of assembly components. Each assembly component includes a hinge module and a mid-frame pressing module. The hinge module includes a K1 hinge component and a K2 hinge component, each containing a K1 receiving portion and a K2 receiving portion. These portions are used to receive the circuit board or the electronic paper display module, and the K1 and K2 hinge components are capable of relative... The device includes a hinge for assembling and connecting the placed circuit board or electronic paper display module into component D; it also includes a component D transfer device and a pressing device; the middle frame pressing module includes a K3 receiving part for receiving the middle frame; the component D transfer device is used to move the component D to the K3 receiving part and place the component D on the receiving middle frame; the pressing device is used to press the component D and the middle frame together to form component E; it also includes a loading position and a unloading position; the loading position and the unloading position are respectively located next to the rotating disk; the loading position is used to place the circuit board in the K1 receiving part, the electronic paper display module in the K2 receiving part, and the middle frame in the K3 receiving part; the unloading position is used to remove component E.

[0010] By fixing the feeding position in component A, the feeding is fixed to the receiving part, making the feeding position accurate. The K1 hinge component can replace manual bonding. The rotating plate distributes the highly ordered processes according to the rotation sequence, which greatly reduces the space of the equipment. At the same time, the rotation can increase the speed of the process and greatly improve the work efficiency. For the mass production of electronic tags, it can achieve an assembly speed of thousands per minute for one set of assembly fixtures.

[0011] To further increase equipment output, the applicant proposes that a rotating disk include more components, including components B and C, which are respectively mounted on the rotating disk, with components A, B, and C equidistant from the center of the rotating disk. Alternatively, it may include components B, C, and D, which are respectively positioned along the angular bisectors of the rotating disk; each of components B, C, or D includes at least one set of the aforementioned assembly components.

[0012] By setting three or four components on the rotating disk, or by increasing the diameter and adding more components, the rotating disk can be rotated 360 degrees to complete the assembly of multiple electronic paper devices.

[0013] The electronic paper display module is a component with smooth upper and lower surfaces and is very fragile. The applicant proposes that the K2 receiving part includes a suction cup, which is used to suction and fix the electronic paper display module. During the hinge process, the K2 hinge component drives the electronic paper display module to flip and move the electronic paper display module above the circuit board.

[0014] Suction cups facilitate the stabilization of smooth, flat components and also make release easier, whereas circuit boards are relatively difficult to fix and move using suction cups. By allowing the electronic paper display module to flip, attract, and release, automated processes can be achieved and run efficiently.

[0015] To improve the unloading of completed components, the applicant proposes that the component D transfer device includes an X-axis track, a Y-axis track, and a suction device. The X-axis track is installed on the Y-axis track, and the suction device is installed on the X-axis track. The suction device is capable of picking up the component D and moving it along the X-axis and Y-axis.

[0016] By setting X-axis and Y-axis tracks, material can be unloaded at different positions, simplifying the unloading mechanism.

[0017] In order to reduce equipment costs and improve the utilization rate of components, the applicant proposed that a component D transfer device be installed at the unloading position, and the component D transfer device be used to remove component E.

[0018] By having the D component transfer device perform two processes, the utilization rate of the D component transfer device is improved, and the overall cost of the equipment is reduced.

[0019] The applicant proposes that the pressing device is mounted on the X-axis track. By mounting the pressing device on the X-axis track, the pressing device can move in both the X and Y directions, enabling it to press components D at different positions.

[0020] The applicant proposes that the pressing device is mounted on the rotating disk; component A also includes a horizontal sliding platform, and the middle frame pressing module is mounted on the horizontal sliding platform.

[0021] Different D-components can be moved to the position of the pressing device via a horizontal sliding platform.

[0022] The applicant proposes that the pressing device includes a Z-axis track and a pressing block, wherein the pressing block is mounted on the Z-axis track and can move on the Z-axis track.

[0023] The D component is pressed together by moving up and down along the Z-axis track. The structure is simple and the pressing distance can be precisely controlled.

[0024] The applicant proposes that the system also includes an air compressor, the cylinder is disposed on the rotating disk, and the hinge module includes a pneumatic push rod, which pushes the K1 hinge component and the K2 hinge component to open or close, and the pneumatic push rod is connected to the air compressor through an air guide pipe.

[0025] By placing the air compressor on a rotating disc, the air hoses will not get tangled during rotation, thus increasing the rotation speed.

[0026] The applicant proposed that it also includes a rotary drive device, which drives the rotating disk to rotate. The rotating disk rotates in one direction, or after rotating 360 degrees, it rotates 360 degrees in the opposite direction to return to the initial position before performing the next round of assembly.

[0027] By rotating 360 degrees and then returning to 0 degrees, the air compressor can be positioned outside the rotating disc and returned to 0 degrees, preventing the air pipe or power cord from breaking due to continuous unidirectional rotation.

[0028] An electronic paper device assembly method, based on the aforementioned electronic paper device assembly fixture, includes the following steps: Step A910: At the loading position, a circuit board is placed in the K1 receiving part, an electronic paper display module is placed in the K2 receiving part, and a middle frame is placed in the K3 receiving part; Step A920: The K1 hinge component and the K2 hinge component are hinged relative to each other, and the placed circuit board or electronic paper display module is combined and connected to form component D; Step A930: Component D is placed on the receiving middle frame, and the pressing device presses the component D and the middle frame into a whole to form component E; Step A940: The component D transfer device removes component E.

[0029] After step A910, step A912 is also included: the K2 receiving part includes a suction cup, which suctions and fixes the electronic paper display module; in step A930: the pressing block moves on the Z-axis track; the middle frame pressing module moves on the horizontal sliding platform, and after the pressing block position and the middle frame pressing module position are aligned, the D component and the middle frame are pressed into a whole to form the E component.

[0030] Beneficial effects: Significantly improves assembly accuracy and yield. Through pneumatically driven automatic flipping hinge, it ensures the alignment and bonding accuracy of the electronic paper display module and the circuit board, eliminating the misalignment problem caused by manual bonding.

[0031] Significantly improves production efficiency: Automated assembly line operation enables the seamless and rapid execution of multiple processes, and the assembly of a finished product can be completed in a single cycle, making production efficiency far exceed that of traditional manual labor.

[0032] Significantly reduces labor intensity and labor costs: Frees operators from the most arduous and repetitive processes such as flipping, aligning, and pressing. In a single assembly cycle, the operator only needs to perform the loading action. Practice has shown that the number of people in the pasting process can be reduced from 3 to 1, and the personnel assembling the middle frame can be completely eliminated.

[0042] Figure 6 The diagram illustrates step 3 of the operation in Example 2. Figure 6 The rotating disk rotates 180 degrees, the hinge module opens, and component D 5020 moves to the 180-degree position.

[0043] Figure 7 The diagram below shows step 4 of the working process in Example 2.

[0044] The component D transfer device includes an X-axis track 7020, a Y-axis track 7010, and a suction device 7030. The X-axis track is mounted on the Y-axis track, and the suction device is mounted on the X-axis track. The suction device is capable of lifting component D and moving it along the X and Y axes.

[0047] In embodiments not shown in the accompanying drawings, the pressing device includes a Z-axis track and a pressing block, the pressing block being mounted on the Z-axis track and movable on the Z-axis track. The D component is pressed by moving up and down along the Z-axis track, resulting in a simple structure and precise control of the pressing distance.

[0048] Figure 8 The diagram below shows step 5 of the operation in Example 2. The D component transfer device moves the completed E component 8010 and E component 8020 onto the conveyor belt 8030 via the suction device 7030. The assembly work is completed.

The suction device 9030 is used for feeding material, placing the material on the conveyor belt 9040 into the receiving cavity.

[0050] like Figure 9 The unloading position is on the right and the loading position is on the left. It also includes a D-component transfer device and a pressing device; the middle frame pressing module includes a K3 receiving part, which is used to receive the middle frame; the D-component transfer device is used to move the D-component to the K3 receiving part and place the D-component on the receiving middle frame; the pressing device is used to press the D-component and the middle frame together to form an E-component; it also includes an loading position and an unloading position; the loading position and unloading position are respectively located next to the rotating disk; the loading position is used to place the circuit board in the K1 receiving part and the electronic paper display module in the K2 receiving part; the middle frame is placed in the K3 receiving part; the unloading position is used to remove the E-component.

[0051] By fixing the feeding position in component A, the feeding is fixed to the receiving part, making the feeding position accurate. The K1 hinge component can replace manual bonding. The rotating plate distributes the highly ordered processes according to the rotation sequence, which greatly reduces the space of the equipment. At the same time, the rotation can increase the speed of the process and greatly improve the work efficiency. For the mass production of electronic tags, it can achieve an assembly speed of thousands per minute for one set of assembly fixtures.

[0052] like Figure 4 It includes three components: component A 4031, component B 4032, and component C 4033. Components B and C are respectively disposed on a rotating disk, and components A, B, and C are equidistant from the center of the rotating disk.

In the figure, each component includes one set of assembly components.

[0053] By setting three or four components on the rotating disk, or by increasing the diameter and adding more components, the rotating disk can be rotated 360 degrees to complete the assembly of multiple electronic paper devices.

[0054] Figure 7 In the middle, the pressing device 7040 is set in one place, suspended in a fixed position and does not rotate with the rotating disk. Alternatively, three pressing devices can be set, one next to each component, which rotate with the rotating disk.

[0055] The electronic paper display module is a component with smooth upper and lower surfaces and is very fragile. The K2 receiving part includes a suction cup, which is used to attract and fix the electronic paper display module. During the hinge process, the K2 hinge component drives the electronic paper display module to flip and move the electronic paper display module above the circuit board.

[0056] Suction cups facilitate the stabilization of smooth, flat components and also make release easier, whereas circuit boards are relatively difficult to fix and move using suction cups. By allowing the electronic paper display module to flip, attract, and release, automated processes can be achieved and run efficiently.

[0057] Figure 8 In this process, the D-component transfer device is installed at the unloading position, and the D-component transfer device is also used to remove the E-component. By having the D-component transfer device perform two processes, the utilization rate of the D-component transfer device is improved, and the overall cost of the equipment is reduced.

[0059] It also includes an air compressor, the cylinder is located below the rotating disk, the hinge module includes a pneumatic push rod, the pneumatic push rod pushes the K1 hinge component and the K2 hinge component to open or close, and the pneumatic push rod is connected to the air compressor through an air guide pipe.

[0060] By placing the air compressor on a rotating disc, the air hoses will not get tangled during rotation, thus increasing the rotation speed.

[0061] It also includes a rotary drive device that drives the rotating disk to rotate. The rotating disk rotates in one direction, or after rotating 360 degrees, it rotates 360 degrees in the opposite direction to return to the initial position before performing the next round of assembly.

[0062] By rotating 360 degrees and then returning to 0 degrees, the air compressor can be positioned outside the rotating disc. Returning to 0 degrees prevents the air pipes or power cables from breaking due to continuous unidirectional rotation.

[0063] Figure 10 Schematic diagram of Example 4.

[0064] It includes four components: component A 10010, component B 10020, component C 10030, and component D 10040, which are respectively set on the angle bisectors of the rotating disk.

The X-axis track is mounted on the Y-axis track, and the suction device is mounted on the X-axis track. The pressing device 10051 is also mounted on the X-axis track.

[0066] Figure 11 The schematic diagram of the hinge module in Embodiment 4 is shown. The hinge module includes a K1 hinge component 11010 and a K2 hinge component 11020, which are connected together by a hinge structure 11030. It includes a K1 receiving portion 11011 and a K2 receiving portion 11021, which are used to receive circuit boards or electronic paper display modules. The K1 and K2 hinge components can be hinged relative to each other to assemble and connect the placed circuit boards or electronic paper display modules into component D. The hinge structure 11030 is pneumatically driven. Pneumatic interfaces 11031 and 11032 are used to connect an external gas compressor. Because the rotating disk rotates, the gas compressor is mounted on the rotating disk, simplifying the gas pipeline layout.

[0067] If the rotating disc is controlled by a program, and it returns to 0 degrees after rotating 360 degrees, the gas compressor can be set up externally. However, this method cannot rotate continuously, and the production speed will be slower.

[0068] Figure 12 A schematic diagram of the pressing device in Embodiment 4 is shown. The pressing device 12051 includes a Z-axis track 12010 and four pressing blocks 12020. The pressing blocks are mounted on the Z-axis track and can move on the Z-axis track. A horizontal sliding platform 12030 is provided, and the middle frame pressing module 12031 is mounted on the horizontal sliding platform and can slide on the horizontal sliding platform for aligning the pressing blocks.

[0069] An embodiment of an electronic paper device assembly method, based on the above-mentioned electronic paper device assembly fixture, includes the following steps: Step A910: At the loading position, a circuit board is placed in the K1 receiving part, an electronic paper display module is placed in the K2 receiving part, and a middle frame is placed in the K3 receiving part; Step A920: The K1 hinge component and the K2 hinge component are hinged relative to each other, and the placed circuit board or electronic paper display module is combined and connected to form component D; Step A930: Component D is placed on the receiving middle frame, and the pressing device presses the component D and the middle frame into a whole to form component E; Step A940: The component D transfer device removes component E.
