Description

Technical Field

[0001] The invention relates to the technical field of electronic component processing, in particular to a method for crimping legs of electronic component processing. Background Art

[0002] Electronic components are basic elements in electronic circuits. They are usually individually packaged and have two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with specific functions, such as amplifiers, radio receivers, oscillators, etc. Crimping refers to the process of crimping the legs (pins) of electronic components together with crimping parts. Generally, the legs of electronic components that need to be crimped are provided with crimping parts. However, manual crimping of the legs of electronic components is inefficient, so a crimping device for processing legs of electronic components is used.

[0003] For example, Chinese invention CN110060948A discloses a device for crimping support legs for processing electronic components, comprising a device body, a fixed base plate and a support leg crimping block, wherein a fixed base plate in the front-to-back direction is arranged at the bottom of the device body, and a conveying concave plate in the front-to-back direction is placed inside the top of the fixed base plate; conveying convex plates are installed on both sides of the conveying concave plate through fixed shafts, and limit adjustment plates are fixedly installed on the conveying concave plate and the top of the conveying convex plate in the front and back; through the arrangement of the conveying concave plate, it is convenient to connect with the conveying convex plate through the fixed shaft to form a conveying feed, and it is convenient to adjust the limit through the limit adjustment plate according to different crimping fixed blocks.

[0004] The above-mentioned reference documents still have the following problems in their actual use: 1. Before the electronic component is crimped, it is difficult to accurately position and fix the electronic component, which easily causes the crimping position of the leg to shift, reducing the accuracy of the leg crimping during electronic component processing.

[0005] 2. For some electronic components stored in poor conditions, dust will adhere to the surface of the electronic components. Before the electronic components are crimped, it is difficult to remove dust from the surface of the electronic components. The dust on the surface of the electronic components will affect the connection quality between the legs and the electronic components during the crimping process. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figures 1 to 7 The present invention provides a method for crimping a leg of an electronic component as follows: The electronic component to be crimped is placed on the top plate 7 in the limiting groove 35, and the electronic component is positioned under the limiting action of the limiting groove 35 to ensure that the electronic component is located directly below the adsorption frame 17, and the electric push rod 20 is controlled to extend to drive the moving block 2 12 to move downward. Under the action of the hinge plate 24, the two moving blocks 1 29 drive the two clamping plates 6 to move toward each other, so as to clamp and fix the electronic component on the top plate 7; As the two moving blocks 1 29 move toward each other, under the action of the connecting rod 28, the piston rod 27 drives the piston plate 34 to move toward the inner side of the piston cylinder 26, and the air in the piston cylinder 26 is discharged into the cleaning tube 15 through the air outlet pipe 38, and is sprayed from the multiple air outlets 16 to clean the electronic components by blowing, so as to blow off the dust and impurities on the surface of the electronic components before the crimping operation; Place the support leg in the adsorption frame 17 and control the hydraulic assembly 4 to drive the connecting plate 2 5 and the adsorption frame 17 to move downward, completing the crimping operation between the support leg in the adsorption frame 17 and the electronic components on the top plate 7; The electric push rod 20 is controlled to retract, driving the moving block 2 12 to move upward, so that the two moving blocks 1 29 move away from each other, releasing the fixation of the electronic components after the crimping operation is completed. As the moving block 2 12 continues to move upward, the top plate 7 is pushed to move upward, and the electronic components after the crimping operation are ejected to the top of the operating table 1, and the finished product is taken out.

[0021] It is worth noting that the method for crimping the support legs of electronic components adopts an operating table 1, a rectangular notch 33 is provided on the surface of the operating table 1, a moving block 29 is slidably connected to the inner wall of the rectangular notch 33, a connecting block 10 is fixedly connected to the upper surface of the moving block 29, a limiting rod 9 is provided on the surface of the connecting block 10, a clamping plate 6 is fixedly connected to the end of the limiting rod 9, a spring 8 is commonly provided between the clamping plate 6 and the connecting block 10, a frame 11 is fixedly connected to the surface of the operating table 1, a limiting groove 35 is provided on the surface of the frame 11, a top plate 7 is slidably connected to the inner wall of the limiting groove 35, a supporting plate 14 is fixedly connected to the surface of the operating table 1, a cleaning pipe 15 passes through the supporting plate 14 and is fixedly connected thereto, a plurality of air outlets 16 are evenly provided on the surface of the cleaning pipe 15, and a fixing component, a material taking component and a cleaning component are provided on the operating table 1.

[0022] A fixed plate 3 is fixedly installed on the upper surface of the operating table 1, and a hydraulic component 4 is arranged on the fixed plate 3. A connecting plate 2 5 is fixedly installed on the output end of the hydraulic component. An adsorption frame 17 and an air pump 18 are both arranged on the connecting plate 2 5. An air extraction pipe 19 is fixedly connected to the surface of the air pump 18. A controller 2 is arranged on the lower surface of the operating table 1.

[0023] The fixed component includes an articulated block 30 fixedly connected to the lower surface of the moving block 29, an electric push rod 20 is fixedly installed on the lower surface of the operating table 1, a connecting plate 21 is fixedly installed on the output end of the electric push rod 20, a moving block 12 is fixedly connected to the end of the connecting plate 21, a hinged block 22 is arranged on the surface of the moving block 12, and a hinged plate 24 is hingedly connected between the articulated block 30 and the articulated block 22.

[0024] Two groups of fixing components are provided, and the two groups of fixing components are symmetrically distributed around the center of the operating table 1 .

[0025] The material picking component includes a connecting rod 23 fixedly connected to the lower surface of the top plate 7, a spring 26 is commonly provided between the top plate 7 and the inner wall of the frame 11, a limiting rod 37 is fixedly connected to the surface of the top plate 7, the end of the limiting rod 37 passes through the frame 11 and is slidably connected thereto, and two groups of springs 26 and limiting rods 37 are provided and correspond one to one.

[0026] In this embodiment, Figure 4 and Figure 5As shown, in this state, the two springs 236 between the top plate 7 and the inner wall of the frame 11 are in an extended state, which controls the electric push rod 20 to extend, driving the connecting plate 121 to move downward. As the connecting plate 12 moves downward, the moving block 12 will be driven to move downward synchronously. As the moving block 12 moves downward, under the action of the elastic potential energy of the springs 236, the connecting rod 123 and the top plate 7 will be driven to move downward synchronously. As the top plate 7 moves downward, a part of the limiting groove 35 will be exposed on the operating table 1. At this time, the electronic components that need to be crimped can be placed on the top plate 7 in the limiting groove 35. The limiting effect of the limiting groove 35 can preliminarily position the electronic components that need to be crimped to ensure that the electronic components are located directly below the adsorption frame 17.

[0027] Then, if Figure 3 As shown, turn on the vacuum pump 18 above the adsorption frame 17, place the support leg inside the adsorption frame 17, and under the action of the vacuum pump 18, the support leg can be fixed in the adsorption frame 17.

[0028] like Figure 7 As shown, the electric push rod 20 is controlled to extend, driving the connecting plate 121 and the moving block 12 to move downward. At the same time, as the moving block 12 moves downward, under the hinged action of the hinged plate 24, the two moving blocks 29 will move towards each other in their corresponding rectangular grooves 33, so that the two clamping plates 6 can be moved towards each other until the two clamping plates 6 are in contact with the electronic components placed on the top plate 7. As the moving block 29 continues to move, the spring 8 between the connecting block 10 and the clamping plate 6 will be compressed. At this time, under the action of the elastic potential energy of the spring 8, the electronic components on the top plate 7 waiting for the support foot crimping operation can be fixed.

[0029] Then, if Figure 2 As shown, by controlling the hydraulic assembly 4 to drive the connecting plate 2 5 and the adsorption frame 17 to move downward, the crimping operation between the support legs in the adsorption frame 17 and the electronic components on the top plate 7 can be completed. Since the electronic components have been fixed by the two clamping plates 6 before the crimping operation, the problem of electronic components being offset due to the crimping force during the crimping process is avoided, thereby avoiding the problem of crimping failure or the production of defective products, improving the accuracy of support leg crimping during electronic component processing, and reducing the production of defective products.

[0030] It is worth noting that after the crimping operation of the electronic components on the top plate 7 is completed, the electric push rod 20 is controlled to retract, driving the connecting plate 21 and the moving block 2 12 to move upward. First, under the hinged action of the hinged plate 24, the two moving blocks 29 will move away from each other, so as to drive the two clamping plates 6 to move away from each other and separate from the electronic components. At this time, the fixation of the electronic components after the crimping operation is completed can be released, and then as the moving block 2 12 continues to move upward, when the moving block 2 12 abuts against the connecting rod 1 23, it will push the connecting rod 1 23 to move upward and reset, so that the top plate 7 can be moved upward and reset, so that the electronic components after the crimping operation are completed can be ejected to the top of the operating table 1, which provides convenience for subsequent operators to take materials.

[0031] In summary, through the linkage cooperation of multiple structures, the electronic components can be preliminarily positioned through the limit groove 35 before the crimping operation, and then the electronic components can be fixed by the relative movement of the two clamping plates 6, ensuring that the electronic components will not be offset during the foot pressing operation, avoiding the problem of crimping failure or defective products, and improving the accuracy of the foot crimping during electronic component processing. After the crimping operation, the electronic components can be released by the reverse movement of the two clamping plates 6, and then the finished electronic components after the crimping operation are ejected by moving the top plate 7 upward, which provides convenience for subsequent operators to take materials and improves the work efficiency during the crimping operation of the electronic component processing feet. It is worthy of promotion and use.

[0032] Embodiment 2, based on the above embodiment: Furthermore, the cleaning component includes a piston plate 34 slidably connected to the inner wall of the piston cylinder 26, the piston cylinder 26 is fixedly mounted on the lower surface of the operating table 1, and the surface of the piston plate 34 is fixedly connected to the piston rod 27; The surface of the moving block 1 29 is fixedly connected with a connecting rod 28 , the end of the piston rod 27 extending out of the piston cylinder 26 is fixedly connected to the connecting rod 28 , the air inlet pipe 32 and the air outlet pipe 38 are both fixedly connected to the surface of the piston cylinder 26 , and the end of the air outlet pipe 38 is fixedly connected to the cleaning pipe 15 .

[0033] A one-way valve 31 is disposed on the surface of the air inlet pipe 32 , and a one-way valve 25 is disposed on the surface of the air outlet pipe 38 .

[0034] In this embodiment, Figure 2 , Figure 4 and Figure 6As shown, when the control electric push rod 20 is contracted so that the two moving blocks 29 move away from each other in their corresponding rectangular slots 33, the piston rod 27 drives the piston plate 34 to move toward the outside of the piston cylinder 26 under the connecting action of the connecting rod 28. This state corresponds to the state when the fixing of an electronic component leg is released after the crimping operation is completed. In this state, the piston cylinder will absorb outside air through the air intake pipe 32 and store it into the inside of the piston cylinder 26.

[0035] When the electric push rod 20 is controlled to retract so that the two moving blocks 29 move toward each other, the piston rod 27 drives the piston plate 34 to move toward the inside of the piston cylinder 26. This state corresponds to a state in which a new electronic component is placed on the top plate 7 waiting for the support leg crimping operation. At this time, the air in the piston cylinder 26 will be discharged into the cleaning tube 15 through the air outlet pipe 38, and will be sprayed from the multiple air outlets 16 on the surface of the cleaning tube 15 to the electronic components waiting for the support leg crimping operation, so as to blow and clean the electronic components, thereby blowing off the dust and impurities on the surface of the electronic components before the crimping operation, thereby avoiding the problem that the dust on the surface of the electronic components affects the connection quality between the support legs and the electronic components during the crimping process, thereby reducing the defective rate.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
