Description

Technical Field

[0001] The present invention relates to an intelligent installation device for keyboard scissor feet. Background Art

[0002] For the assembly of a computer keyboard, generally, scissor feet and keycaps are installed on a keyboard main board with a circuit. Among them, the scissor feet are a commonly used part, mainly including inner and outer frames that intersect and are rotatably pivoted, and their function is to make the keycaps have a certain elasticity. During the assembly process of the keyboard, first, the scissor feet are inserted into the corresponding positions on the keyboard main board, and then the keycaps are pressed into these positions. The most difficult part in the installation is to send the scissor feet that are closely arranged in sequence supplied by the feeding tray to each scissor foot installation position. Existing technologies include two devices with publication numbers CN110491708A and CN210731563U. When these two devices send the scissor feet to each working position, extremely complex conveying mechanisms are required, which not only have extremely high costs but also have extremely complex mechanisms, and are prone to many problems such as inaccurate feeding. Summary of the Invention

The material distribution mechanism is installed on the Z-direction driving nut.

[0009] Optimized, the guiding component includes a guiding plate, and a through groove that is wider at the top and narrower at the bottom is formed on the guiding plate.

[0010] Furthermore, pressing plates are provided on both sides of the through groove on the guiding plate. The pressing plates have a part covering the upper part of the through groove to prevent the sliding column from falling off from the through groove.

[0011] 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 is used to lift the scissor feet.

[0012] Optimized, the limiting member includes a limiting column fixed above each sliding column, a limiting piece sleeved on adjacent two limiting columns. A limiting hole is formed on the limiting piece, and the limiting column passes through the limiting hole and can slide in the limiting hole along the direction of the sliding columns separating or approaching. When any adjacent two sliding columns approach to the closest distance, each sliding column corresponds to the scissor feet to be taken and closely attached in the feeding guide rail respectively. When any adjacent two sliding columns separate to the farthest distance, the scissor feet on each sliding column correspond to the scissor foot mounting positions on the keyboard fixed on the receiving plate respectively.

[0013] Optimized, the telescopic power part includes a first telescopic member and a guiding block installed on the guiding component. One end of the guiding block is connected to one end of the first telescopic member, and the other end is connected to the end of the limiting member or to the sliding column at the end.

[0017] Due to the application of the above technical scheme, the present invention has the following advantages compared with the prior art: the present invention uses a limiter to control the position of the scissor feet after dispersion, so that when the scissor feet are separated to the maximum position driven by the material separation mechanism, they just correspond precisely to the installation positions of each scissor foot on the keyboard; the material separation mechanism, driven by the material picking and pressing assembly, lifts the scissor feet from the feeding guide rail and moves them toward the keyboard to be installed, while separating the scissor feet arranged closely in sequence to the spacing distance corresponding to the installation positions on the keyboard; after moving into position, the three-way moving part drives the separation mechanism to move the scissor feet to the keyboard. The material mechanism moves downward, accurately pressing each scissor foot into each installation position, then the stripping plate presses down to push the scissor foot out of each material taking column, the material taking and pressing device resets, and the receiving plate sends the keyboard with the scissor foot installed out of the receiving table, then the keyboard is taken away manually for inspection, and the receiving plate resets to the upstream with the conveyor belt to continue to receive the next keyboard without scissor foot installed, while the material taking and pressing device continues to extract the scissor foot to install the next keyboard without scissor foot installed, and this cycle is repeated. The limiter is exquisitely designed, simple in structure, low in cost, but accurate in positioning and high in assembly yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The feeding device 3 includes a vibrating bowl 31 and a feeding guide rail 32 connected to the vibrating bowl 31. The feeding guide rail 32 includes a front section guide rail 33 and a rear section guide rail 34. The front section guide rail 33 is provided with a guiding groove 35 with a large belly and a small mouth. The scissor feet 0 are arranged in the guiding groove 35 and vibrate forward along the guiding groove 35 without falling. The rear section guide rail 34 includes a bottom guide rail 36 and a guide rail cover plate 37. The conveying device 2 includes a frame 21 and a conveyor belt 22 arranged on the frame 21. The conveyor belt 22 and the vibrating bowl 31 are prior arts and not the focus of this application, so they will not be elaborated here.

[0029] The picking and pressing device 1 includes a receiving plate 11, a receiving table 12, a material distribution mechanism 13, and a three-way moving part 14.

[0030] The upper end surface of the receiving table 12 is the reference surface. The direction parallel to the reference surface and parallel to the feeding direction of the feeding guide rail 32 is the Y-axis direction. The direction parallel to the reference surface and perpendicular to the Y-axis direction is the X-axis direction. The direction perpendicular to the reference surface is the Z-axis direction. The three-way moving part 14 drives the material distribution mechanism 13 to move along the X / Y / Z-axis directions. The receiving table 12 includes a base 15 and a support frame 16 installed on the base 15. The three-way moving part 14 includes an X-axis lead screw mechanism 17, a Y-axis lead screw mechanism 18, and a Z-axis lead screw mechanism 19 installed on the support frame 16. The X-axis lead screw mechanism 17 is arranged along the X-axis direction, and its driving nut is the X-axis driving nut, which moves along the X-axis direction. The Y-axis lead screw mechanism 18 is installed on the X-axis driving nut and is arranged along the Y-axis direction. Its driving nut is the Y-axis driving nut, which moves along the Y-axis direction. The Z-axis lead screw mechanism 19 is installed on the Y-axis driving nut and is arranged along the Z-axis direction. Its driving nut is the Z-axis driving nut, which moves along the Z-axis direction. The material distribution mechanism 13 is installed on the Z-axis driving nut.

[0031] The material distribution mechanism 13 includes a guiding component 10, a plurality of sliding columns 110 slidably installed in the guiding component 10, a telescopic power part 111 for driving the sliding columns 110 to separate or approach, a limiting member 112 for limiting the maximum distance of separation of the sliding columns 110, and a stripping component 113 installed on the guiding component 10.

[0032] The guiding component 10 includes a guiding plate 114, and a through slot 115 that is wider at the top and narrower at the bottom is formed in the guiding plate 114. Pressing plates 116 are fixedly arranged on both sides of the through slot 115 on the guiding plate 114. The pressing plates 116 have a part covering the upper part of the through slot 115 to prevent the sliding column 110 from falling off the through slot 115, and a plurality of mounting holes 117 are formed therein.

[0033] The sliding column 110 includes a sliding block 118 and a material taking column 119 fixedly connected to the lower end surface of the sliding block 118. The sliding block 118 is slidably connected in the through slot 115, and the material taking column 119 extends downward and has a part extending out of the through slot 115. The material taking column 119 is inserted into a circular hole in the middle of the scissor leg 0 and is used to fix the scissor leg 0 when lifting.

[0034] The limiting member 112 includes a limiting column 120 fixed above each sliding column 110, a limiting piece 121 sleeved on adjacent two limiting columns 120, and a limiting hole 122 formed in the limiting piece 121. The limiting hole 122 is an oval hole. Two limiting holes 122 corresponding to the limiting columns 120 are formed in each limiting piece 121. The limiting column 120 passes through the limiting hole 122 and can slide in the limiting hole 122 along the direction in which the sliding columns 110 are separated or approximated. When any two adjacent sliding columns 110 are approximated to the closest distance, the two limiting columns 120 in the same limiting piece 121 are located on the closer sides of the two limiting holes 122. Each sliding column 110 corresponds to a scissor leg 0 to be taken and in close contact in the feeding guide rail 32 respectively. When any two adjacent sliding columns 110 are separated to the farthest distance, the two limiting columns 120 in the same limiting piece 121 are located on the separated sides of the two limiting holes 122. The scissor legs 0 on each sliding column 110 correspond to the scissor leg 0 mounting positions on the keyboard fixed on the receiving plate 11 respectively.

[0035] The telescopic power part 111 includes a first telescopic member 123 and a guiding block 124 mounted on the guiding component 10. One end of the guiding block 124 is connected to one end of the first telescopic member 123, and the other end is connected to the end of the limiting member 112 or is connected to the sliding column 110 at the end. The first telescopic member 123 is a cylinder, which includes a cylinder body and a piston rod. The cylinder body of the first telescopic member 123 is fixedly installed on the pressing plate 116 through a mounting base plate 129 and the mounting holes 117, and then is fixedly connected to the guiding plate 114. The piston rod is fixedly connected to one end of the guiding block 124. The other end of the guiding block 124 is connected to the end of the limiting member 112 or is fixedly connected to the sliding column 110 at the end. The guiding block 124 has two downward extending extension segments. There are multiple rows of sliding columns 110, and every two rows of sliding columns 110 are connected to the two extension segments of a guiding block 124.

[0036] The blanking component 113 includes a second telescopic member 125, a blanking plate 126 connected to the telescopic rod of the second telescopic member 125 and located below the guide plate 114. The cylinder body of the second telescopic member 125 is provided on the guide plate 114 and the telescopic rod passes through the guide plate 114. A through groove 127 corresponding to the sliding column 110 is provided on the blanking plate 126. The telescopic rod of the second telescopic member 125 expands and contracts along the Z-axis direction. The width of the through groove 127 is greater than the diameter of the lower end of the sliding column 110 and less than the width of the scissor leg 0.

[0037] 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 middle circular hole of the scissor leg 0, 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 leg 0, so that the scissor leg 0 can be positioned at the middle section during material taking.

[0038] Briefly speaking, this device uses the limiting member 112 to control the position of the scissor legs 0 after dispersion, so that when the scissor legs 0 are separated to the maximum position driven by the material distribution mechanism 13, they exactly correspond to the installation positions 130 of each scissor leg 0 on the keyboard one by one, realizing fast and accurate installation.

[0039] Specifically, initially, the first telescopic member 123 contracts to gather the multi-row sliding columns 110 in rows. At this time, each sliding column 110 corresponds to the scissor leg 0 to be taken and closely attached in the rear section guide rail 34 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. The material distribution mechanism 13 drives by the three-way moving part 14 and moves downward along the Z-axis direction until the middle section of the material taking column 119 is inserted into the circular hole of the scissor leg 0. Subsequently, the guide rail cover plate 37 is withdrawn along the conveying direction and will not interfere with the material taking column 119. The material taking column 119 lifts the multi-row scissor legs 0 that are successively close to each other from the rear section guide rail 34 at one time. Then, the three-way moving part 14 drives the material distribution mechanism 13 to move towards the keyboard to be installed. The first telescopic member 123 extends 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, the three-way moving part 14 drives the material distribution mechanism 13 to move downward along the Z-axis direction to accurately press each scissor leg 0 into each installation position on the keyboard fixed on the receiving plate 11. Subsequently, the second telescopic member drives the blanking plate 126 to press down to push the scissor legs 0 out of each material taking column 119. The material taking and pressing device 1 resets. The receiving plate 11 sends out the keyboard with the scissor legs 0 installed to the receiving table 12, and then the keyboard is taken away by the operator for inspection. The receiving plate 11 resets to the upstream along with the conveyor belt 22 to continue receiving the next keyboard without installed scissor legs 0, and the material taking and pressing device 1 continues to extract the scissor legs 0 for the installation of the next keyboard without installed scissor legs 0. In this way, it circulates repeatedly. The limiting member 112 is exquisitely designed, simple in structure, low in cost, but accurate in positioning and high in assembly yield.
