Description

Technical Field

[0001] The invention relates to a limiting component of a keyboard scissor foot intelligent installation device. Background Art

[0002] The assembly of a computer keyboard usually involves installing the scissor feet and keycaps on a keyboard motherboard with circuits. Among them, the scissor feet are a commonly used part, mainly including inner and outer frames that cross each other and are rotatably pivoted, and their function is to make the keycaps have a certain degree of elasticity. During the assembly process of the keyboard, the scissor feet are first inserted into the corresponding positions of the keyboard motherboard, and then the keycaps are pressed into the positions. The most difficult problem to overcome during the installation is to deliver the scissor feet that are closely arranged in sequence supplied by the feed tray to each scissor foot installation position. The existing technologies include: such as the two devices with publication numbers: CN110491708A and CN210731563U. These two devices require extremely complex conveying mechanisms when delivering the scissor feet to each workstation, and there is a problem that the conveying accuracy is not high enough. Summary of the invention

[0003] The purpose of the present invention is to provide a limit assembly of a keyboard scissor foot intelligent installation device with a sophisticated structure and precise conveying position.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is: a limit assembly of a keyboard scissor foot intelligent installation device, which includes:

[0005] The guide part comprises a guide plate, and the guide plate is provided with a plurality of through grooves which are wide at the top and narrow at the bottom;

[0006] A plurality of sliding posts are provided and divided into a plurality of groups, each group corresponding to each of the through slots, and each group of sliding posts is slidably installed in the through slots;

[0007] A stroke control unit, which is used to limit the maximum distance that the slide columns are separated, or to limit the maximum and minimum distances that the slide columns are separated, comprises a limit column fixed above each of the slide columns, a limit plate sleeved on two adjacent limit columns, a limit hole being provided on the limit plate, the limit column being passed through the limit hole and being able to slide in the limit hole along the direction of separation or convergence of the slide columns, when any two adjacent slide columns are brought together to the shortest distance, each of the slide columns corresponds one-to-one to the scissor feet to be taken and tightly attached in the feeding guide rail, and when any two adjacent slide columns are separated to the farthest distance, the scissor feet on each of the slide columns correspond one-to-one to the scissor foot mounting positions fixed on the keyboard.

[0008] Optimally, a pressure plate is provided on the guide plate and on both sides of the through slot, and the pressure plate partially covers the top of the through slot to prevent the sliding column from falling off the through slot.

[0009] Optimized, the sliding column includes a slider and a material taking column fixed to the lower end surface of the slider. The slider is slidably connected in the through groove, and the material taking column extends downward and has a part extending out of the through groove. The material taking column is inserted into the scissor feet and used to lift the scissor feet.

[0010] Further, when the limiting piece defines the maximum distance and the minimum distance for the separation of the sliding columns, two limiting holes corresponding to the limiting columns are respectively formed in each limiting piece. The limiting columns are inserted into the limiting holes and can slide in the limiting holes along the direction of separation or approach of the sliding columns. When any two adjacent sliding columns approach to the closest distance, the two limiting columns in the same limiting piece are located on the closer sides of the two limiting holes. Each sliding column corresponds to one of the scissor feet to be taken and closely attached in the feeding guide rail respectively. When any two adjacent sliding columns are separated to the farthest distance, the two limiting columns in the same limiting piece are located on the separated sides of the two limiting holes. The scissor feet on each sliding column respectively correspond to the scissor foot mounting positions on the keyboard fixed to the receiving plate one by one.

[0011] Further, when the limiting piece only defines the maximum distance for the separation of the sliding columns, one limiting hole is formed in each limiting piece. Two adjacent limiting columns are inserted into the same limiting hole and can slide in the limiting hole along the direction of separation or approach of the sliding columns. When any two adjacent sliding columns approach to the closest distance, the side walls of the sliding columns opposite to each other are in contact. Each sliding column corresponds to one of the scissor feet to be taken and closely attached in the feeding guide rail respectively. When any two adjacent sliding columns are separated to the farthest distance, the two limiting columns in the same limiting hole are located on the separated sides of the limiting hole. The scissor feet on each sliding column respectively correspond to the scissor foot mounting positions on the keyboard fixed to the receiving plate one by one.

[0012] Further, the slider is in the shape of a cuboid or a cylinder.

[0013] Further, the lower end of the material taking column is in a conical shape. The diameter of the middle section is slightly larger than the diameter of the middle circular hole of the scissor feet, and the two are in interference fit. The diameter of the upper end is larger than the diameter of the middle circular hole of the scissor feet, so that the scissor feet can be positioned at the middle section during material taking.

[0014] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art: The present invention uses the stroke control part to control the position of the scissor feet after dispersion, so that the scissor feet are exactly and accurately corresponding to the mounting positions of the scissor feet on the keyboard when separated to the maximum position. The stroke control part is exquisitely designed, has a simple structure, low cost, but accurate positioning and high assembly yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0021] First embodiment

[0022] As Figures 1-3 shown

[0023] The limit assembly includes: a guiding part, a slide column, and a stroke control part.

[0024] The guiding part 10 includes a guiding plate 114, and a through groove 115 that is wider at the top and narrower at the bottom is formed on the guiding plate 114. Pressing plates 116 are fixedly arranged on both sides of the through groove 115 on the guiding plate 114. The pressing plates 116 have a part covering the upper part of the through groove 115 to prevent the slide column 110 from falling out of the through groove 115, and a plurality of mounting holes 117 are provided thereon.

[0025] There are multiple slide columns 110, which are divided into multiple groups, and each group corresponds to each of the through grooves 115. Each group of slide columns 110 is slidably installed in the through groove 115; each slide column 110 includes a slider 118 and a material taking column 119 fixed to the lower end surface of the slider 118. The slider 118 is slidably connected in the through groove 115, and the material taking column 119 extends downward and has a part extending out of the through groove 115. The material taking column 119 is inserted into the round hole in the middle of the scissor foot 0, and it is used to fix the scissor foot 0 when lifting. The lower end of the material taking column 119 is conical, the diameter of the middle section 128 is slightly larger than the diameter of the round hole in the middle of the scissor foot 0, and the two are in interference fit. The diameter of the upper end is larger than the diameter of the round hole in the middle of the scissor foot 0, so that the scissor foot 0 can be positioned at the middle section 128 during material taking.

[0026] The stroke control part is used to limit the maximum distance and the minimum distance at which the sliding columns are separated. It includes a limit column 120 fixed above each sliding column 110, a limit piece 121 sleeved on adjacent two limit columns 120, a limit hole 122 opened on the limit piece 121. The limit hole 122 is an oblong hole. Two limit holes 122 corresponding to the limit columns 120 respectively are opened on each limit piece 121. The limit column 120 penetrates through the limit hole 122 and can slide in the limit hole 122 along the direction in which the sliding columns 110 are separated or approximated. When any adjacent two sliding columns 110 are approximated to the closest distance, the two limit columns 120 within the same limit piece 121 are located on the closer sides of the two limit holes 122. Each sliding column 110 corresponds to one of the scissor feet 0 to be picked up and closely attached in the feeding guide rail respectively. When any adjacent two sliding columns 110 are separated to the farthest distance, the two limit columns 120 within the same limit piece 121 are located on the separated sides of the two limit holes 122. The scissor feet 0 on each sliding column 110 respectively correspond to the installation positions of the scissor feet 0 on the keyboard fixed on the receiving plate 11 respectively.

[0027] In the initial state, the sliding columns 110 are gathered in rows. At this time, each sliding column 110 corresponds to one of the scissor feet 0 to be picked up and closely attached respectively. The spacing between the material picking columns 119 in each row is the same as the spacing between the rows of scissor feet 0 that are approximated in sequence. When picking up materials, the middle section of the material picking column 119 is inserted into the round hole of the scissor foot 0. The material picking column 119 lifts up the rows of scissor feet 0 that are approximated in sequence at one time, and then moves towards the keyboard to be installed. The slider extends under the action of an external force (which can be driven by a cylinder or an oil cylinder, not the focus of this application and will not be elaborated again) to separate the scissor feet 0 arranged closely in sequence to the interval distance corresponding to the installation positions on the keyboard. After moving and separating in place, it descends under the action of an external force to accurately send each scissor foot 0 into each installation position 130 on the keyboard fixed on the receiving plate 11. The stroke control part 112 is exquisitely designed, simple in structure, low in cost, but accurate in positioning and high in assembly yield.

[0028] Embodiment 2

[0029] As Figure 1 、 4 shown in -5,

[0030] The limit component includes: a guiding part, a sliding column and a stroke control part.

[0031] The guiding part 10 includes a guiding plate 114. An upper-wide and lower-narrow through groove 115 is opened on the guiding plate 114. Pressing plates 116 are fixedly arranged on both sides of the through groove 115 on the guiding plate 114. The pressing plates 116 have parts covering above the through groove 115 to prevent the sliding column 110 from falling off from the through groove 115, and a plurality of mounting holes 117 are arranged thereon.

[0032] The sliding columns 110 are multiple and divided into multiple groups, and each group corresponds to each of the through grooves 115 respectively. Each group of the sliding columns 110 is slidably installed in the through groove 115; each sliding column 110 includes a slider 118 and a material taking column 119 fixed to the lower end surface of the slider 118. The slider 118 is slidably connected in the through groove 115, and the material taking column 119 extends downward and has a part extending out of the through groove 115. The material taking column 119 is inserted into the round hole in the middle of the scissor leg 0, and it is used to fix the scissor leg 0 when lifting. The lower end part of the material taking column 119 is conical. The diameter of the middle section 128 is slightly larger than the diameter of the round hole in the middle of the scissor leg 0, and the two are in interference fit. The diameter of the upper end part is larger than the diameter of the round hole in the middle of the scissor leg 0, so that the scissor leg 0 can be positioned at the middle section 128 during material taking.

[0033] The stroke control part is only used to limit the maximum distance at which the sliding columns are separated. It includes a limit post 120 fixed above each sliding column 110, a limit piece 121 sleeved on adjacent two limit posts 120. A limit hole 122 is opened on the limit piece 121. The limit hole 122 is an oblong hole. Two limit holes 122 corresponding to the limit posts 120 respectively are opened on each limit piece 121. The limit post 120 passes through the limit hole 122 and can slide in the limit hole 122 along the direction in which the sliding columns 110 are separated or close to each other. When any two adjacent sliding columns 110 are close to the closest distance, the opposite side walls of the sliders 118 of the two adjacent sliding columns 110 are in contact. Each sliding column 110 corresponds to a scissor leg 0 to be taken and closely attached in the feeding guide rail respectively. When any two adjacent sliding columns 110 are separated to the farthest distance, the two limit posts 120 in the same limit piece 121 are located on the separated sides of the limit hole 122. The scissor legs 0 on each sliding column 110 respectively correspond to the scissor leg 0 installation positions on the keyboard fixed to the receiving plate 11 respectively.

[0034] In the initial state, the sliding columns 110 are gathered in rows. At this time, each sliding column 110 corresponds to a scissor leg 0 to be taken and closely attached respectively. The spacing between the material taking columns 119 in each row is the same as the spacing between the scissor legs 0 in each row that are successively close to each other. When taking materials, the middle section of the material taking column 119 is inserted into the round hole of the scissor leg 0, and the material taking column 119 lifts the multiple rows of scissor legs 0 that are successively close to each other at one time. Then it moves towards the keyboard to be installed. The slider extends under the action of an external force (which can be driven by a cylinder or an oil cylinder, not the focus of this application, and will not be elaborated again) to separate the scissor legs 0 arranged closely in sequence to the interval distance corresponding to the installation positions on the keyboard. After moving and separating in place, it descends under the action of an external force to accurately send each scissor leg 0 into each installation position 130 on the keyboard fixed to the receiving plate 11. The stroke control part 112 is exquisitely designed, simple in structure, low in cost, but accurate in positioning and high in assembly yield.

[0035] The above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it should not be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
