Description

Technical Field

[0001] The invention relates to the technical field of notebook computer assembly, and in particular to an automatic feeding device for a notebook keyboard balance bar. Background Art

[0002] As far as the current usage habits of personal computers are concerned, the keyboard is one of the indispensable input devices for inputting text, symbols or numbers. In addition, consumer electronic products in daily life or large-scale processing equipment used in the industrial sector are generally equipped with a key structure as an input device to operate the above-mentioned electronic products and processing equipment.

[0003] Generally speaking, most of the keys on keyboard devices have square keycaps, and a small number of keys such as the space key, the input key, the shift key, etc. have keycaps that are longer than they are wide. These keys are called multiple keys. Because the key surface of multiple keys is longer, when users type on the keyboard, their fingers cannot guarantee that they will hit the center of the keycap. When they hit the side of the keycap, they need to apply greater pressure to the keycap to trigger the key effect. Therefore, a balance bar is added between the keycap and the keyboard to prevent the keycap from tilting or rising due to the difference in the receiving point, so that both ends of the keycap can achieve a balanced effect.

[0004] The balance bar in the existing keyboard is formed by bending a straight bar with a circular cross section, the middle straight bar part is the balance part, the two sides of the balance bar are bent side ends, and both side ends are provided with hook parts; the balance part of the balance bar is installed on the cap, and the keyboard is provided with a hole groove for the installation of the hook part. In the existing technology, when assembling the balance bar, the balance bar is installed in the hole groove on the keyboard by relying on gravity to fall freely, which is easy to cause material jamming and delay the installation period.

[0011] In the present application, a straight vibrator is used to provide power to achieve horizontal feeding. Compared with the existing technology, the feeding is converted from free fall relying on gravity to horizontal feeding, which solves the problem of material jamming during free fall relying on gravity. The present application also provides a material channel width adjustment mechanism to install balance bars of different lengths to improve the installation effect.

Therefore, the applicant also designed a balancing structure, which is located at the rear end of the feeding plate and can well balance the vibration of the material channel.

It should be noted that the first arm 511 and the second arm 512 are respectively located on the outer side of the keyboard plate.

[0054] In the present application, a straight vibrator is used to provide power to achieve horizontal feeding. Compared with the existing technology, the feeding is converted from free fall relying on gravity to horizontal feeding, which solves the problem of material jamming during free fall relying on gravity. The present application also provides a material channel width adjustment mechanism to install balance bars of different lengths to improve the installation effect. The present application accurately delivers the balance bar into the hole groove on the keyboard through the linkage cooperation of the support arm assembly, the up and down displacement mechanism and the front and back displacement mechanism.

[0055] Specifically, Figure 1 and Figure 3 As shown, the first left-right displacement mechanism includes a stepper motor 311 installed on the lower side of the feeding plate 1, the output shaft of the stepper motor 311 is connected to the driving wheel 312, the driving wheel 312 is connected to the driven wheel 314 through a conveyor belt 313, the driven wheel 314 is connected to the screw rod 315, the screw rod 315 is provided with a nut 316, and the upper end of the nut 316 is connected to the connecting piece 317.

[0056] In this way, the present application utilizes a stepper motor and a screw rod structure to adjust the width of the material channel, thereby solving the problem of low efficiency of the existing manual adjustment of the width of the material channel.

[0057] Specifically, Figure 2 As shown, the feed plate 1 is provided with a plurality of first slide grooves 11 extending in the left-right direction, and the lower side of the second L-shaped plate 22 is provided with a plurality of first sliders corresponding to the first slide grooves 11, and the second L-shaped plate is slidably matched with the first slide grooves 11 through the first sliders.

[0058] In this way, when adjusting the width of the material channel, the second L-shaped plate can be limited to a certain extent to ensure that the second L-shaped plate can move vertically and avoid the second L-shaped plate from being offset.

[0059] Specifically, Figure 5 As shown, the second left-right displacement mechanism 55 includes a second slider 551 provided on the support plate 54 and extending along the left-right direction, and a sliding fitting portion 552 slidably fitted with the second slider 551 , and the upper side of the sliding fitting portion 552 is connected to the second support arm 512 .

[0060] In this way, it is ensured that when the width of the material channel is adjusted, the second arm can also move together with the second L-shaped plate, so that the first arm and the second arm can directly adapt to balance rods of different lengths, greatly improving the efficiency of adjusting the width of the material channel.

[0061] Specifically, Figure 5 As shown, a vertically extending slide bar 553 is also connected to the upper side of the sliding fitting portion 552, and a third slide block 554 is sleeved on the slide bar 553. A groove 555 is provided at the front section of the second L-shaped plate 22 near the first L-shaped plate 21, and the third slide block 554 is slidably arranged in the groove 555. During implementation, a third guide rail is also provided in the groove 555, and the third slide block 554 is slidably fitted with the third guide rail.

[0062] In the present application, the front-to-back and up-and-down displacements of the second arm are for facilitating the precise installation of the balance bar on the keyboard panel, and the left-to-right displacements of the second arm are for enabling the width adjustment of the material channel. The structure of the present application enables the front-to-back, left-to-right and up-and-down displacements of the second arm to be performed independently without interfering with each other. In this way, after the width of the material channel is adjusted, it still has the characteristic of precise installation of the balance bar, greatly enhancing the versatility of the present application.

The limiting structure 563 is in the shape of an inverted L-shaped plate, and the limiting protrusion 566 of the guide arm 562 is located on the inner side of the limiting structure 563.

[0065] In this way, without affecting the function of the first cylinder to achieve vertical up and down displacement of the support plate and the components on the support plate, the upward extension length of the first cylinder is also limited to prevent the balance rod from completely separating from the material channel upward.

[0066] Specifically, Figure 7 and Figure 8 As shown, the front-to-rear displacement mechanism 53 includes a second cylinder 532 installed on a base plate 531 and extending forward and backward. A through groove is provided on the base plate 531 corresponding to the telescopic axis portion of the second cylinder 532. The telescopic axis of the second cylinder 532 is connected to the mounting plate 57 via a connector 533 passing through the through groove.

[0067] In this way, the forward and backward movement of the mounting plate is controlled by the second cylinder, thereby controlling the forward and backward movement of the first cylinder on the mounting plate, and finally controlling the forward and backward movement of the first arm and the second arm to complete the loading.

[0068] Specifically, Figure 7 and Figure 8 As shown, at least one second guide ridge 534 is disposed on the upper side of the bottom plate 531 , and a second guide rail 535 slidably matched with the second guide ridge 534 is disposed on the lower side of the mounting plate 57 .

[0071] The applicant discovered that since a straight vibrator was used in the present application to achieve horizontal feeding, the material channel would vibrate to a certain extent due to the influence of the straight vibrator, which may cause inaccurate feeding of the balance bar. Therefore, the applicant also designed a balancing structure, which is located at the rear end of the feeding plate and can well balance the vibration of the material channel.

[0072] The working principle and use process of the present application are as follows: first, the width of the material channel is adjusted by the first left-right displacement mechanism and the second left-right displacement mechanism 55 to adapt to the length of the balance bar 7; then the straight vibrator 4 is started to move the balance bar 7 horizontally from the back to the front; when the balance bar 7 moves to the front end of the material channel and is located above the mounting groove 513 of the support arm assembly 51, the up-down displacement mechanism 52 pushes the support plate 54 and the support arm assembly 51 on the support plate 54 upward, so that the mounting groove 513 of the first support arm 511 and the second support arm 512 supports the balance bar 7; then, the front-back displacement mechanism 53 drives the mounting plate 57 and the up-down displacement mechanism 52 on the mounting plate 57 to move forward, so that the support arm assembly 51 will drive the balance bar 7 to move forward, and when the balance bar 7 moves to the top of the hole groove on the keyboard plate, the support arm assembly 51 is moved downward by the up-down displacement mechanism 52 until the balance bar 7 is installed on the hole groove of the keyboard plate; finally, the front-back displacement mechanism 53 drives the support arm assembly 51 to move backward again to prepare for the installation of the next balance bar 7.
