Description

Technical Field

[0001] This utility model relates to the field of assembly fixture technology, and in particular to a semi-automatic assembly fixture for installing buttons. Background Technology

[0002] In the manufacturing process of electronic products, the button assembly of product C is a critical step. After applying quick-drying adhesive to the button assembly area, the buttons on product C need to be assembled in the shortest possible time and held under pressure for at least 5 seconds to ensure accurate adhesion during the adhesive curing process. Simultaneously, the entire assembly tolerance must be within + / -0.05mm, requiring extremely high precision. However, the current manual assembly method has many problems: firstly, button positioning is difficult, and when misalignment is detected, manual correction is required, holding the button under pressure for at least 5 seconds, resulting in extremely low work efficiency; secondly, adhesive easily overflows during manual operation, leading to the scrapping of the entire product and increasing production costs. Therefore, developing a dedicated button assembly fixture to meet high-requirement assembly needs at a very low cost is urgently needed.

[0003] To address the aforementioned problems, this utility model document proposes a semi-automatic assembly fixture for installing buttons. Utility Model Content

[0004] The purpose of this utility model is to solve the many problems of manual assembly in the existing technology: on the one hand, the buttons are difficult to position, and when assembly misalignment is found, manual correction is required, and the button must be pressed for more than 5 seconds, resulting in extremely low work efficiency; on the other hand, glue is easy to overflow during manual operation, which leads to the scrapping of the entire product and increases production costs. Therefore, a semi-automatic assembly fixture for installing buttons is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A semi-automatic assembly fixture for installing buttons, comprising:

[0007] A control console with a timed pressure holding function has a button positioning module and a product positioning module fixed to its top by bolts. A mounting bracket is fixedly installed on the top of the control console, and a left and right translation module is installed inside the mounting bracket. A button assembly up and down mechanism is installed on the moving seat of the left and right translation module, and a button picking module is provided at the cylinder output end of the button assembly up and down mechanism.

[0008] In one possible design, corresponding buttons A and B are embedded in the two grooves on the top of the button positioning module.

[0009] In one possible design, product C is inserted and fixed onto a plug on one side of the product positioning module.

[0010] In one possible design, the contact surface of the button-collecting module is designed with the same curved shape as buttons A / B to ensure more stable positioning during button collection and assembly, and more balanced force distribution when pressed down.

[0011] In one possible design, the button suction module has two symmetrically arranged embedded suction cups inside to ensure a more secure suction and a more stable position during machine operation.

[0012] In one possible design, the top of the button-collecting module is provided with a spring-loaded buffer structure to prevent damage to the product and to make the pressing action resilient.

[0013] In this application, upon initial use, the operator inserts buttons A / B into the corresponding grooves on the top of the button positioning module to ensure accurate positioning of buttons A / B. Simultaneously, product C is inserted and fixed onto the insert rod on one side of the product positioning module, completing the pre-placement of materials. After starting the fixture, the control console issues a command, and the drive motor of the left and right translation module rotates, driving the moving seat to move left or right through the transmission mechanism, so that the button assembly upper and lower mechanism and the button suction module move above the button positioning module. When the button suction module reaches directly above buttons A / B, the cylinder of the button assembly upper and lower mechanism is activated, the cylinder piston rod extends, and the button suction module descends until the contact surface of the button suction module contacts buttons A / B. At this time, the vacuum generator is activated, causing the embedded suction cup inside the button suction module to generate negative pressure and suck up buttons A / B.

[0014] After buttons A / B are picked up, the piston rod of the cylinder in the button assembly mechanism retracts, causing the button picking module and buttons A / B to rise. Then, the drive motor of the left and right translation module runs again, causing the moving seat to move in the opposite direction, so that the button assembly mechanism and the button picking module carry buttons A / B to the top of the product positioning module, that is, above the button assembly position of product C. The piston rod of the cylinder in the button assembly mechanism extends again, causing the button picking module and buttons A / B to fall, installing buttons A / B onto product C. During the button pressing process, the spring buffer structure at the top of the button picking module plays a buffering role, enabling the button to self-position and preventing damage to the product. At this time, the control console starts timing to perform timed pressure holding to ensure that the glue cures. The pressure holding time is set according to the glue curing time and product requirements, generally not less than 5 seconds.

[0015] After the pressure holding time is over, the control console issues a command, the cylinder piston rod of the button assembly mechanism retracts, driving the button picking module to rise. At the same time, the left and right translation module drives the button assembly mechanism and the button picking module back to their initial positions, completing one button assembly operation. The operator takes out the assembled product C and puts in a new product to be assembled, and performs the next assembly operation.

[0016] This utility model has the following beneficial effects:

[0017] This utility model fixture is simple, stable, easy to operate and maintain, and has greatly improved efficiency and quality. Because the button positioning feature is too small, it is not easy to install quickly during manual assembly. This fixture can transform this task into other indirect positioning designs with higher accuracy.

[0018] This utility model features a multi-stage button-collecting mechanism that ensures the button's appearance is not damaged during collection, installation, and pressure holding, while maintaining high installation accuracy throughout the assembly process. By increasing the pressure holding time, the equipment investment for two pressure holding operations is reduced, and the pressure holding action can be combined to minimize the risk of adhesive failure, allowing the button to be assembled as early as possible.

[0019] This utility model has a simple positioning and is easy to maintain, and it has sufficient displacement space to move its position during pressure holding. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1-5 An assembly fixture mainly consists of a control console 1, a button positioning module 2, buttons A / B 3, a product positioning module 4, product C 5, a mounting bracket 6, a left-right translation module 7, a button assembly up-and-down mechanism 8, and a button picking module 9. These components work together to achieve semi-automatic button assembly.

[0029] The control console 1 has a timed pressure holding function. The pressure sensor detects the pressure during the pressure holding process in real time and transmits the signal to the control system. The control system compares the pressure with the preset pressure value and adjusts the pressure through the pressure regulating valve to ensure that the pressure during the pressure holding process is stable within the set range. At the same time, the timing component starts timing to monitor the pressure holding time. When the pressure holding time reaches the preset value, the timing component sends a signal to the control system. The control system controls the cylinder to stop extending and retracting, and the pressure holding head is raised to complete the pressure holding process.

[0030] The top of the control console 1 is fixedly installed with bolts to the button positioning module 2 and the product positioning module 4, providing a positioning base for the buttons and products. The top of the control console 1 is also fixedly installed with a mounting bracket 6 for installing the left and right translation module 7. The control console 1 controls the operation of the entire fixture, including the movement of the left and right translation module 7, the up and down movement of the button assembly up and down mechanism 8, and the setting and control of the pressure holding time.

[0031] The top of the button positioning module 2 has two grooves, the shape and size of which match the buttons A / B 3. The buttons A / B 3 are embedded in the corresponding grooves. Through the positioning function of the grooves, the position of buttons A / B 3 on the fixture is ensured to be accurate, providing precise positioning for the subsequent picking up and assembly of the buttons.

[0032] The product positioning module 4 has a plug rod on one side. The shape and size of the plug rod are adapted to the plug hole of product C5. Product C5 is plugged into and fixed on the plug rod to achieve the positioning of the product on the fixture. The design of the product positioning module 4 is simple, which facilitates the placement and removal of the product, and at the same time ensures the stability of the product during the button assembly process.

[0033] Mounting bracket 6 is fixed to the top of console 1, providing installation space for left and right translation modules 7. Mounting bracket 6 is made of high-strength material, with a stable structure, and can withstand the force generated when the left and right translation modules 7 move, ensuring the stability of the entire fixture during operation.

[0034] The left and right translation module 7 is installed in the mounting frame 6. The transmission mechanism of the left and right translation module 7 is usually composed of a drive motor, transmission components (such as a gear and rack mechanism), and a moving seat. Among them, the gear and rack mechanism is widely used in industry to convert rotary motion into linear motion. During operation, the drive motor starts running under the control of the control console 1. The output shaft of the drive motor is connected to the gear through a rigid connection such as a keyway, transmitting the rotary motion to the gear. The gear and rack mesh with each other. When the gear rotates, the rotary motion is converted into linear motion through the rack. The rack can be fixed on the frame and remain stationary, while the gear drives the moving seat connected to it to move linearly along the rack direction. The moving seat is connected to the linear guide rail through a slider to ensure stability and accuracy during movement. When the gear drives the moving seat to move, the slider slides along the linear guide rail to achieve smooth left and right translation of the moving seat. The moving seat is equipped with a button assembly up and down mechanism 8. Through the movement of the left and right translation module 7, the position of the button assembly up and down mechanism 8 and the button picking module 9 in the horizontal direction is adjusted so that they can accurately reach above the button positioning module 2 and the product positioning module 4.

[0035] The button assembly mechanism 8 is mounted on the movable seat of the left and right translation module 7. It is mainly composed of cylinders. The cylinders realize the extension and retraction movement under the control of the control console 1. The output end is equipped with a button picking module 9. Through the extension and retraction movement of the cylinders, the button picking module 9 is driven to move up and down to complete the picking up, pressing down and assembling of buttons.

[0036] The button picking module 9 is installed at the cylinder output end of the button assembly upper and lower mechanism 8. Its contact surface is provided with a curved anti-conformity structure similar to that of button A / B 3. This anti-conformity structure allows the button picking module 9 to fit better with button A / B 3, making the positioning more stable when picking up and assembling the button, and the force more even when pressing down, thereby improving the assembly accuracy of the button.

[0037] The button suction module 9 has two symmetrically arranged embedded suction cups inside. The suction cups are connected to the vacuum generator through pipes. When the button suction module 9 moves above button A / B 3 and descends to contact the button, the vacuum generator is activated, which generates negative pressure inside the suction cup, thereby firmly suctioning button A / B 3, ensuring a more secure suction and a more stable position during machine operation.

[0038] This application can be used in the field of semi-automatic assembly of button installation, or in other fields applicable to this application.

[0039] Example 2

[0040] Improvements based on Example 1:

[0041] A semi-automatic assembly fixture for installing buttons, which is applied to the field of assembly fixtures;

[0042] Please refer to Figure 4 The top of the button-collecting module 9 is equipped with a spring buffer structure, which consists of a spring and a guide rod. When the button is pressed down, the spring buffer structure can play a buffering role, preventing the button-collecting module 9 from applying too much pressure to the product C5, preventing damage to the product, making the pressing action more resilient, and at the same time allowing the button to self-position under pressure, further improving the assembly accuracy of the button.

[0043] However, as is well known to those skilled in the art, the working principles and wiring methods of the left-right translation module 7, the button assembly up-down mechanism 8, and the button pickup module 9 are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0044] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
