Abstract
Description
Technical Field
[0001] This invention relates to the field of button bar assembly equipment technology, specifically a precision positioning button bar assembly device. Background Technology
[0002] In modern electronic products, automotive control panels, home appliances and industrial control equipment, button sticks are a basic human-computer interaction component with extremely wide applications. Due to their small size, manual assembly of button sticks is difficult, so button stick assembly devices are usually used to assemble them. Existing button assembly devices typically use grippers to hold the button bar during assembly, while a cylinder moves the button bar to the upper side of the base. At this point, the pusher moves, squeezing the button bar contacts on both sides of the button bar so that the contacts fit into the button bar. Then, the secondary cylinder operates, moving the button bar further downward and inserting it into the base, thus completing the button bar assembly operation. Existing precision positioning button assembly devices require a pushing contact to squeeze the button contact during assembly, and a two-stage cylinder to drive the button to the base for assembly. This complex structure increases costs and assembly time. Therefore, we propose a precision positioning button assembly device. Summary of the Invention

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0015] Please see Figure 1-4 This embodiment provides a technical solution: a precision positioning button rod assembly device, including a base plate 1, an adjustable upper and lower sliding plate 13 on the upper side of the base plate 1, a material carrier 16 on the front side of the base plate 1, an assembly base 15 on the left side of the base plate 1, and an assembly mechanism 14. The assembly mechanism 14 includes a clamping block 141, a compression spring 142, an assembly clamp 143, and an assembly positioning pin 144. The clamping block 141 is fixedly connected to the front surface of the upper and lower sliding plate 13, and the assembly clamp 143 is slidably connected to the assembly pin 144. The chuck 143 has an assembly positioning pin 144 slidably connected inside it. The upper end of the assembly positioning pin 144 is fixedly connected to the chuck block 141. A compression spring 142 is fixedly connected between the upper surface of the stepped surface on the lower side of the outer surface of the chuck 143 and the lower surface of the chuck block 141. The chuck 143 can be disassembled from the inside of the chuck block 141, and the compression spring 142 can be replaced to avoid the compression spring 142 becoming less elastic after long-term use and thus failing to function properly.
[0016] like Figure 1As shown, the upper surface of the base plate 1 is fixedly connected to symmetrically distributed support plates 2. The upper end of the right support plate 2 is fixedly connected to a lower limiting block 11 for material handling position. A hanging plate 3 is fixedly connected between the two support plates 2. A linear slide rail 4 is fixedly connected to the front surface of the hanging plate 3. A left and right sliding plate 9 is slidably connected to the front surface of the linear slide rail 4. A left and right cylinder 7 is fixedly connected to the right side of the upper surface of the hanging plate 3. The left end of the telescopic end of the left and right cylinder 7 is fixedly connected to the right surface of the left and right sliding plate 9. When an external air compressor is operated, which can be set behind the base plate 1, the telescopic ends of the left and right cylinder 7 are retracted, causing the left and right sliding plates 9 to move to the right. During the downward movement of the telescopic ends of the left and right cylinder 7, the left and right sliding plates 9 and the linear slide rail 4 maintain a sliding connection. The radial force is borne by the sliding support between the left and right sliding plates 9 and the linear slide rail 4. Therefore, the left and right cylinder 7 is subjected to very little force in the radial direction, ensuring that the left and right cylinder 7 is only subjected to force in the axial direction, and avoiding damage to the left and right cylinder 7 due to excessive radial force.
[0017] like Figure 1 As shown, a left limiting block 6 for the material picking position is fixedly connected to the left side of the front surface of the hanging plate 3, and a right limiting block 5 for the material picking position is fixedly connected to the right side of the front surface of the hanging plate 3. Buffers 8 are symmetrically distributed on the left and right sides and are fixedly connected to the front surface of the hanging plate 3. The right surface of the left and right sliding plates 9 contacts the left end of the piston rod of the buffer 8. Simultaneously, the buffer 8 buffers the left and right sliding plates 9. The buffer 8 is an adjustable hydraulic buffer. When the left and right sliding plates 9 impact the piston rod of the buffer 8, it pushes the hydraulic oil in the piston compression chamber inside the buffer 8, forcing the oil through a pre-designed micro-throttling orifice or gap, thereby generating a strong damping force. During this process, the kinetic energy of the object is converted into the heat energy of the oil and dissipated, ultimately achieving a smooth, shock-free deceleration and stop. The left limiting block 6 and the right limiting block 5 for the material picking position limit the left and right sliding plates 9, preventing them from exceeding their maximum movable range.
[0018] like Figure 1 As shown, a linear slide rail 2 is fixedly connected to the front surface of the left and right slide plates 9, and an upper and lower slide plates 13 are slidably connected to the front surface of the linear slide rail 2. An upper and lower cylinder 10 is fixedly connected to the upper surface of the left and right slide plates 9, and the lower side of the telescopic end of the upper and lower cylinder 10 is fixedly connected to the upper surface of the upper and lower slide plates 13.
[0019] During the downward movement of the telescopic ends of the upper and lower cylinders 10, the upper and lower slide plates 13 maintain a sliding connection with the linear slide rail 2. The radial force is borne by the sliding support between the upper and lower slide plates 13 and the linear slide rail 2. Therefore, the upper and lower cylinders 10 experience very little force in the radial direction, ensuring that the upper and lower cylinders 10 are only subjected to force in the axial direction, thus preventing damage due to excessive radial force. The upper end of the telescopic ends of the upper and lower cylinders 10 is fixedly connected to the lower limit block 12 of the assembly position. Operating the external air compressor causes the telescopic ends of the upper and lower cylinders 10 to move downward. The upper and lower cylinders 10 are dual-axis double-stroke adjustable cylinders. When the telescopic ends of the upper and lower cylinders 10 move downward, the piston rod inside the upper and lower cylinders 10 moves downward, driving the upper and lower slide plates 13 along the linear slide rail 2. The slide rail 2 moves downward, causing the clamp block 141 to move downward, which in turn moves the assembly clamp 143 downward. At this time, the assembly head 143 is located directly above the button bar placed on the upper side of the loading platform 16. When the piston rod inside the upper and lower cylinders 10 moves downward, the lower limit block 12 of the assembly position is also moved downward because the upper end of the piston rod inside the upper and lower cylinders 10 is fixedly connected to the lower limit block 12 of the assembly position. When the lower surface of the lower limit block 12 of the assembly position contacts the upper surface of the lower limit block 11 of the material picking position, the piston rod inside the upper and lower cylinders 10 stops moving. At this time, the button bar is inserted into the assembly clamp 143. Button bar contacts are fixedly connected to the left and right surfaces of the button bar. The button bar contacts are elastic metal sheets.
[0020] When the button bar is inserted into the assembly chuck 143, the inner wall of the assembly chuck 143 presses against the button bar contact, and the friction between the button bar contact and the inner wall of the assembly chuck 143 fixes the button bar inside the assembly chuck 143. Then, the external air compressor is operated to retract and reset the telescopic ends of the upper and lower cylinders 10. Next, the telescopic ends of the left and right cylinders 7 extend, causing the left and right slide plates 9 to move to the left until the left surface of the slide plates 9 contacts the right end of the piston rod of the left-side buffer 8. At this point, the telescopic ends of the upper and lower cylinders 10 extend downwards, causing the upper and lower slide plates 13 to move downwards, which in turn causes the chuck block 141 to move downwards, resulting in the assembly chuck 143 moving downwards and the button bar moving downwards. When the button bar is located on the upper side of the base placed on the upper side of the assembly base 15, when the button bar moves downward and contacts the base, the button bar is inserted into the interior of the base. Then the clamp block 141 continues to move downward, so that the lower end of the assembly pin 144 presses against the upper surface of the button bar. At this time, the assembly clamp 143 is lifted, and the compression spring 143 contracts. When the lower surface of the lower limit block 12 of the assembly position contacts the upper surface of the upper and lower cylinders 10, it indicates that the assembly is in place. At this time, the telescopic end of the upper and lower cylinders 10 contracts and moves upward. Under the friction of the button bar and the base, the button bar separates from the assembly clamp 143. At the same time, the compression spring 143 relaxes, driving the assembly clamp 143 to reset, thereby realizing the assembly operation of the button bar.
[0021] The working principle of the precision positioning button rod assembly device provided by the present invention is as follows: During assembly, an external air compressor is operated. This compressor can be positioned behind the base plate 1, causing the telescopic ends of the left and right cylinders 7 to retract, moving the left and right sliding plates 9 to the right. This brings the right surface of the sliding plates 9 into contact with the left end of the piston rod of the buffer 8. Simultaneously, the buffer 8 acts as a buffer for the sliding plates 9. The buffer 8 is an adjustable hydraulic buffer. When the left and right sliding plates 9 impact the piston rod of the buffer 8, it pushes the hydraulic oil in the piston compression chamber inside the buffer 8, forcing the oil through pre-designed micro-throttling orifices or gaps, thereby generating a strong damping force. During this process… The kinetic energy of the object is converted into the heat energy of the oil and dissipated, ultimately achieving a smooth and shock-free deceleration and stop. At this time, the external air compressor is operated to move the extension and retraction ends of the upper and lower cylinders 10 downward. The upper and lower cylinders 10 are dual-axis double-stroke adjustable cylinders. When the extension and retraction ends of the upper and lower cylinders 10 move downward, the piston rod inside the upper and lower cylinders 10 moves downward, which drives the upper and lower slide plates 13 to move downward along the direction of the second linear slide rail, causing the clamp block 141 to move downward, which in turn drives the assembly clamp 143 to move downward. At this time, the assembly head 143 is located directly above the button bar placed on the upper side of the loading platform 16.
[0022] When the piston rod inside the upper and lower cylinders 10 moves downward, the lower limit block 12 of the assembly position is fixedly connected to the upper end of the piston rod inside the upper and lower cylinders 10. Therefore, the lower limit block 12 of the assembly position also moves downward. When the lower surface of the lower limit block 12 of the assembly position contacts the upper surface of the lower limit block 11 of the material picking position, the piston rod inside the upper and lower cylinders 10 stops moving. At this time, the button bar is inserted into the assembly chuck 143. Button bar contacts are fixedly connected to the left and right surfaces of the button bar. The button bar contacts are elastic metal sheets. When the button bar is inserted into the assembly chuck 143, the inner wall of the assembly chuck 143 squeezes the button bar contacts. Then, the button bar is fixed inside the assembly chuck 143 by the friction between the button bar contacts and the inner wall of the assembly chuck 143.
[0023] Next, operate the external air compressor to retract and reset the telescopic ends of the upper and lower cylinders 10. Then, extend the telescopic ends of the left and right cylinders 7, causing the left and right slide plates 9 to move to the left until the left surface of the left and right slide plates 9 contacts the right end of the piston rod of the left buffer 8. At this time, extend the telescopic ends of the upper and lower cylinders 10 and move them downward, causing the upper and lower slide plates 13 to move downward, causing the chuck block 141 to move downward, causing the assembly chuck 143 to move downward, and causing the button bar to move downward. At this time, the button bar is located on the upper side of the base placed on the upper side of the assembly seat 15. When the button bar moves downward and contacts the base, the button bar inserts. The assembly is connected to the inside of the base. Then, the clamp block 141 continues to move downward, so that the lower end of the assembly pin 144 presses against the upper surface of the button bar. At this time, the assembly clamp 143 is lifted, and the compression spring 143 contracts. When the lower surface of the lower limit block 12 of the assembly position contacts the upper surface of the upper and lower cylinders 10, it indicates that the assembly is in place. At this time, the telescopic end of the upper and lower cylinders 10 contracts and moves upward. Under the friction of the button bar and the base, the button bar separates from the assembly clamp 143. At the same time, the compression spring 143 relaxes, driving the assembly clamp 143 to reset, thereby realizing the assembly operation of the button bar.
