Description

Technical Field

[0001] The present application relates to the technical field of keyboard scissor foot production, and in particular to a scissor foot material collection and detection integrated device and an operation method thereof. Background Art

[0002] With the rapid development of modern information technology, the supporting electronic devices are also developing rapidly, such as laptops, smart phones, etc. The keyboard is a key component of the computer. The commonly used keyboard structures on the market include scissor foot structure, crater structure and column structure.

[0003] Reference Figure 1 The scissor leg structure generally includes an outer scissor 100 and an inner scissor 200. The outer scissor 100 is penetrated with an outer scissor through hole 101, and the inner scissor 200 is penetrated with an inner scissor through hole 201. Mounting holes 102 are provided on both inner sides of the outer scissor through hole 101 in the length direction, and mounting shafts 202 are provided on both sides of the inner scissor 200 in the length direction. During installation, the two mounting shafts 202 on the inner scissor 200 are respectively inserted into the mounting holes 102, so that the inner scissor 100 can rotate along the axis of the mounting shaft 202.

[0004] At present, after the internal and external shears are assembled in batch production, they need to undergo a quality inspection process. The inspection process is to determine whether the installation shaft of the internal shear is properly plugged into the installation hole of the external shear in the assembled scissor legs, so as to ensure that the internal shear can rotate around the axis of the installation shaft. The inspection process in the existing related technology is to place the assembled scissor legs on a spiral vibration plate. The scissor legs undergo a spiral vibration feeding process. If the installation shaft is not properly plugged into the installation hole, the internal and external shears will be separated by the vibration force. Subsequent unqualified products will be vibrated into a waste box, while qualified products will be collected, thereby completing the material collection and inspection process.

[0005] However, the above-mentioned material collection and testing process requires first collecting the material and then testing. After two steps, the testing efficiency is low; and multiple scissor legs are mixed together in the vibration plate, and the vibration force they are subjected to is relatively large, which may cause the originally qualified products to be unqualified due to external force collision, and the detection accuracy is not high. Summary of the invention

[0006] In order to solve the above technical problems, the present application provides a scissor leg material picking detection integrated device, which has the advantages of high detection accuracy and high detection efficiency.

[0007] In the first aspect, the present application provides a scissor foot material taking and detection integrated device, and its technical solution is as follows:

[0008] A scissor foot material taking and detection integrated device, comprising:

[0009] A plurality of vertically arranged material taking rods, wherein the material taking rods can be raised and lowered in the vertical direction;

[0010] An elastic member is fixedly sleeved on the outer side wall of the bottom end of the material taking rod, and the scissor legs are sleeved on the outside of the elastic member;

[0011] A detection lever is vertically arranged on one side of the material taking lever, the detection lever is arranged one by one in correspondence with the material taking lever, the detection lever can be raised and lowered in the vertical direction, and the detection lever is used to move the external shear in the vertical direction;

[0012] And a stripping component for stripping the scissor legs after detection.

[0013] To implement the above technical solution, the process of material picking and detection is as follows: multiple material picking rods move downward at the same time until the bottom end of the material picking rod is inserted into the inner shear through hole, that is, the inner shear is sleeved on the outside of the elastic part, and the elastic part is deformed, thereby giving the inner hole of the inner shear an outward friction force, and the scissor legs are lifted as a whole when the material picking rod moves upward, completing the material picking process; then the detection lever moves vertically downward to move the outer shear, and if the outer shear can rotate along the axis of the installation shaft, the scissor legs are well assembled; if the outer shear is separated from the inner shear, since the outer shear is difficult to rotate around the axis of the installation shaft, the detection lever will simultaneously drive the inner shear to separate from the material picking rod, and finally the remaining scissor legs on the material picking rod are qualified assembled products, and the qualified products are subsequently removed by the stripping assembly. By using this device, the material picking detection function can be realized at the same time, improving the detection efficiency; and the detection lever is used to accurately detect each scissor leg individually, thereby improving the detection accuracy.

[0014] As a preferred solution of the present application, a limiting groove is provided on the elastic member, and the limiting groove is used for the insertion and fixation of the internal shear.

[0015] To implement the above technical solution, when the scissor legs are mounted on the material picking rod, the inner shear is mounted in the limiting groove, and the limiting groove can fix the inner shear more stably, so that the inner shear will not slip off the outer shear when the detection lever moves the outer shear, thereby ensuring the accuracy of the detection.

[0016] As a preferred solution of the present application, the lower surface of the limiting groove is set as an inclined surface downward.

[0017] By implementing the above technical solution, while ensuring that the limiting groove limits the inner shear, when the inner shear is subsequently peeled off the feeding rod using the peeling assembly, the inclined surface reduces the resistance of the limiting groove to the inner shear, making the peeling process easier, thereby improving the peeling efficiency.

[0018] As a preferred embodiment of the present application, the stripping assembly includes a horizontally arranged stripping plate, a plurality of stripping rods vertically arranged on the bottom surface of the stripping plate, and a stripping cylinder for driving the stripping plate to move in the vertical direction. The bottom end of the stripping rod is abutted against the inner shear, and at least two stripping rods are provided, and the plurality of stripping rods are evenly arranged along the circumferential direction of the material picking rod.

[0019] In order to implement the above technical solution, a specific structure of a peeling assembly is proposed. When in use, the material return cylinder is started to drive the material return plate to move vertically downward, thereby driving the material return rod to abut against the upper surface of the inner shear. The material return rod is evenly arranged along the circumferential direction of the material picking rod, thereby giving the inner shear a uniform vertical thrust, so that the inner shear can be peeled off from the material picking rod better and more efficiently.

[0020] As a preferred solution of the present application, a guide groove is vertically provided on the material taking rod, and the material returning rod is slidably arranged in the guide groove.

[0021] The above technical solution is implemented to improve the stability of the movement of the material-removing rod.

[0022] As a preferred solution of the present application, a side surface of the detection lever facing the material picking lever is set as a plane.

[0023] To implement the above technical solution, when the detection rod moves vertically downward, the scissor foot close to one side of the detection rod is in contact with the detection rod, and setting the side of the detection rod as a plane will allow the detection rod to limit the scissor foot, thereby preventing the scissor foot from rotating around the axis of the material picking rod, thereby ensuring that the scissor foot can be stably and accurately placed in the material receiving place when it is subsequently removed, thereby improving the accuracy of material picking detection.

[0024] As a preferred solution of the present application, a shifting protrusion is provided on the side of the detection lever facing the material picking lever, and the side of the detection lever facing the material picking lever is in contact with one end of the length direction of the external shear in the horizontal state.

[0025] The implementation of the above technical solution makes it more accurate when the detection lever moves the outer shear downward, and the detection lever can better limit the outer shear to avoid displacement of the scissor legs, thereby ensuring the stability of subsequent peeling.

[0026] As a preferred solution of the present application, the shifting protrusion is configured to be in an arc shape.

[0027] The present application also provides a scissor foot material taking detection integrated method, based on the scissor foot material taking detection integrated device according to claims 1-8, which comprises the following steps:

[0028] Step 1, move the material taking rod downward so that the inner shear sleeve is set in the limit groove;

[0029] Step 2, move the material rod upward so that the scissor legs are suspended;

[0030] Step 3, detection process: the detection lever moves down, the external shear is moved, the detection lever moves up, and returns to the initial position;

[0031] Step 4. Start the material return cylinder to drive the material return rod to remove the scissor legs that have been inspected.

[0032] As a preferred solution of the present application, in Step 3, a waste collection plate is provided below the material taking rod, and between Step 3 and Step 4 there is the following step Step 34: pulling out the waste collection plate and placing a good product collection plate.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. The scissor legs can be taken out by setting a material taking rod and an elastic member, and the scissor legs can be taken out immediately after the material is taken out by using a detection lever, and finally the scissor legs after the detection are taken out by using a stripping component, realizing the integrated function of material taking and detection, thereby improving the detection efficiency and detection accuracy;

[0035] 2. By setting the side of the detection lever facing the material picking lever as a plane, the detection lever can avoid displacement of the inner shear during detection, ensuring the stability of the inner shear position, thereby ensuring the accuracy of detection and the accuracy of subsequent scissor legs when being peeled off;

[0036] 3. By providing a limit groove on the elastic member and setting the lower surface of the limit groove as an inclined surface, the internal shear is made more stable during detection, thereby improving the accuracy of detection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The following is combined with Figure 2-6 This application is described in further detail.

[0046] Example 1

[0047] Reference Figure 2 , is a scissor foot material taking detection integrated device disclosed in the embodiment of the present application. The scissor foot material taking detection integrated device comprises a horizontally arranged workbench 50, a plurality of placement slots 53 for placing the scissor feet are arranged on the upper surface of the workbench 50, a through hole 54 is vertically opened on the bottom surface of each placement slot 53, and an inverted 3-shaped frame 51 is vertically arranged on the upper surface of the workbench 50, and the frame 51 serves as a supporting body of the material taking detection device.

[0048] Reference Figure 2 and Figure 3 A material taking assembly for taking materials is provided above the workbench 50. The material taking assembly includes a material taking cylinder 11 vertically fixedly arranged on the top surface of the frame 51, and the piston rod of the material taking cylinder 11 penetrates downwardly through the top surface of the frame 51; it also includes a material taking plate 12 horizontally arranged at the bottom end of the piston rod of the material taking cylinder 11; it also includes a plurality of material taking rods 1 vertically arranged on the bottom surface of the material taking plate 12. In this embodiment, the material taking rods 1 are set to be cylindrical, and can also be regular rectangular. The material taking plate 12 can be driven by the material taking cylinder 11 to rise and fall in the vertical direction. In order to ensure the stability of the movement of the material taking plate 12, limit columns 52 are vertically fixedly arranged at both ends of the length direction of the bottom surface of the frame 51, and the limit columns 52 vertically penetrate the material taking plate 12.

[0049] Reference Figure 3The diameter of the bottom end of the material taking rod 1 is smaller than the diameter of other parts of the rod. An elastic member 2 is fixedly sleeved on the outer wall of the bottom end of the material taking rod 1. In this embodiment, the elastic member 2 is set as a thin rubber sleeve, which can also be a metal elastic sleeve or a rubber sleeve, and the diameter of the thin rubber sleeve gradually increases from bottom to top. When in use, the thin rubber sleeve is inserted into the inner shear through hole, and the deformation of the elastic member 2 gives the inner shear through hole an outward friction force along the diameter direction of the inner shear through hole, thereby fixing the inner shear, so that the scissor legs can be taken out.

[0050] Reference Figure 3 and Figure 4 In order to improve the stability of the material picking rod 1 when picking materials, a limiting groove 5 is horizontally opened on the outer wall of the elastic member 2. The lower surface of the limiting groove 5 is inclined downward. The diameter of the limiting groove 5 is slightly larger than the diameter of the inner shear through hole, thereby further ensuring the stable material picking process of the inner shear.

[0051] Reference Figure 2 and Figure 3 A detection component for detecting whether the scissor legs are assembled properly is also provided above the workbench 50. The detection component includes a detection cylinder 31 vertically arranged at the center of the top surface of the frame 51, and the piston rod of the detection cylinder 31 vertically penetrates the frame 51 downward; it also includes a detection plate 32 horizontally arranged at the end of the piston rod of the detection cylinder 31, the detection plate 32 is located above the feeding plate 12, and the piston rod of the feeding cylinder 11 vertically penetrates the detection plate 32; it also includes a plurality of detection levers 3 vertically arranged on the bottom surface of the detection plate 32, the detection levers 3 are provided with a plurality of and one-to-one correspondence with the feeding levers 1, and the detection levers 3 vertically penetrate the feeding plate 12.

[0052] Reference Figure 3 , a toggle protrusion 7 is provided at the bottom end of the detection lever 3 near the material picking rod 1, and the toggle protrusion 7 is set in an arc shape. The detection process is as follows: when the detection lever 3 moves vertically downward, the toggle protrusion 7 pushes the outer shear downward, thereby driving the outer shear to rotate around the axis of the installation shaft. If the assembly is qualified, the outer shear can rotate freely around the installation shaft, and at this time the inner shear will be stably fixed in the limit groove 5; if the assembly is unqualified, the outer shear will be separated from the inner shear under the thrust of the toggle protrusion 7, or the inner shear will be driven downward to separate from the material picking rod 1, thereby judging whether the scissor leg assembly is qualified. In order to ensure the stability of the inner shear during detection, the other part of the detection lever 3 facing the material picking rod 1 except the toggle protrusion 7 is set as a plane, so as to prevent the inner shear from rotating along the axis of the material picking rod 1.

[0053] Reference Figure 2 and Figure 3The scissor foot material picking detection device also includes a stripping assembly for removing the scissor feet after detection, and the stripping assembly includes a stripping cylinder 43 vertically arranged at the center of the top surface of the frame 51, and the piston rod of the stripping cylinder 43 vertically penetrates the top surface of the frame 51 and is arranged downward; and a stripping plate 41 horizontally arranged at the end of the piston rod of the stripping cylinder 43, the stripping plate 41 is located above the material picking plate 12, and the stripping plate 41 is located below the detection plate 32, that is, the detection plate 32, the stripping plate 41, and the material picking plate 12 are arranged in sequence from top to bottom; it also includes a stripping rod 42 vertically arranged on the bottom surface of the stripping plate 41, and a plurality of stripping rods 42 are provided, and each group of stripping rods 42 is evenly arranged along the circumferential direction of the material picking rod 1, and each group of stripping rods 42 corresponds to a material picking rod 1.

[0054] Combination Figure 4 In this embodiment, each group of material-removing rods 42 is provided with two rods, and are symmetrically arranged with respect to the diameter of the material-collecting rod 1. A guide groove 6 is vertically provided on the side wall of the material-collecting rod 1, and a guide block 61 is provided on the side surface of the material-removing rod 42 facing the material-collecting rod 1. The guide block 61 slides vertically along the guide groove 6, thereby ensuring the stability of the vertical movement of the material-removing rod 42. After the detection is completed, the material-removing cylinder 43 is started to drive the material-removing plate 41 to move vertically downward, thereby driving the material-removing rod 42 to withdraw the complete scissor leg.

[0055] Reference Figure 2 and Figure 5 In the embodiment of the present application, the implementation principle of detecting and taking materials is as follows:

[0056] Step 1: The assembled scissor legs are placed horizontally in the placement slot 53, and the material taking cylinder 11 is started to drive the material taking rod 1 to move downward until the bottom end of the material taking rod 1 extends into the inner shear through hole, and the material taking rod 1 moves upward to lift the scissor legs;

[0057] Step 2: Place a waste collection plate on the upper surface of the workbench 50, start the detection cylinder 31, drive the detection lever 3 to move downward, move the protrusion 7 to move the outer shear, and inspect the assembly status.

[0059] Repeat the above steps.

[0060] Example 2

[0061] The difference from Example 1 is that an exhaust pipe is provided on one side of the length direction of the workbench 50, and the exhaust pipe draws away the waste on the upper surface of the workbench 50, so that there is no need to place a waste collection plate, and finally the qualified products are directly stripped to the upper surface of the workbench 50 by the stripping assembly.

[0062] Example 3

[0063] Reference Figure 6 , is a material collection and detection integrated method disclosed in an embodiment of the present application. Based on the above-mentioned material collection and detection integrated device, the method includes the following steps:
