Description

Technical Field

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

[0002] Electronic components are fundamental elements in electronic circuits, typically individually packaged and possessing two or more leads or metal contacts. They must be interconnected to form a circuit with a specific function, such as an amplifier, radio receiver, or oscillator. Crimping involves pressing the legs (pins) of electronic components together with a crimping tool. These components typically come with crimping tools, but manual crimping is inefficient, leading to the use of crimping devices for electronic component legs.

[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 provided 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 provision 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 referenced documents still have the following problems in their actual use:

[0005] 1. Before the electronic component legs are crimped, it is difficult to accurately position and fix the electronic component, which can easily cause the crimping position of the legs to shift, reducing the accuracy of the leg crimping during electronic component processing.

[0006] 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

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0037] For example 1, please refer to Figures 1 to 7 The present invention provides a method for crimping the legs of electronic components as follows:

[0038] The electronic component to be crimped is placed on the top plate 7 in the limiting groove 35. The electronic component is positioned under the limiting action of the limiting groove 35 to ensure that the electronic component is directly below the adsorption frame 17. The electric push rod 20 is controlled to extend, driving 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, clamping and fixing the electronic component on the top plate 7.

[0039] 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 inside of the piston cylinder 26 , and the air in the piston cylinder 26 is discharged into the cleaning pipe 15 through the air outlet pipe 38 , and then sprayed out from the multiple air outlets 16 to clean the electronic components, thereby blowing off dust and impurities on the surface of the electronic components before the crimping operation;

[0040] Place the legs 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 legs in the adsorption frame 17 and the electronic components on the top plate 7;

[0041] 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 upward to eject the electronic components after the crimping operation is completed to the top of the operating table 1 for finished product removal.

[0042] It is worth noting that the electronic component processing support leg crimping method adopts an operating table 1, the surface of the operating table 1 is provided with a rectangular notch 33, the inner wall of the rectangular notch 33 is slidably connected with a moving block 29, the upper surface of the moving block 29 is fixedly connected with a connecting block 10, the surface of the connecting block 10 is provided with a first limiting rod 9, the end of the first limiting rod 9 is fixedly connected with a clamping plate 6, and a spring 8 is commonly provided between the clamping plate 6 and the connecting block 10, the surface of the operating table 1 is fixedly connected with a frame 11, the limiting groove 35 is provided on the surface of the frame 11, the top plate 7 is slidably connected to the inner wall of the limiting groove 35, the surface of the operating table 1 is fixedly connected with a support plate 14, the cleaning pipe 15 passes through the support 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 the operating table 1 is provided with fixing components, material taking components and cleaning components.

[0043] 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. The adsorption frame 17 and the vacuum pump 18 are both arranged on the connecting plate 2 5. The surface of the vacuum pump 18 is fixedly connected to an exhaust pipe 19. A controller 2 is provided on the lower surface of the operating table 1.

[0044] 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, the end of the connecting plate 21 is fixedly connected to the moving block 2 12, and an articulated block 22 is provided on the surface of the moving block 2 12, and an articulated plate 24 is hinged between the articulated block 30 and the articulated block 22.

[0045] 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 .

[0046] The material-taking component includes a connecting rod 23 fixedly connected to the lower surface of the top plate 7, a spring 2 36 is commonly provided between the top plate 7 and the inner wall of the frame 11, a second limiting rod 37 is fixedly connected to the surface of the top plate 7, and the end of the second limiting rod 37 passes through the frame 11 and is slidably connected thereto, and two groups of springs 36 and second limiting rods 37 are provided and correspond one to one.

[0047] In this embodiment, Figure 4 and Figure 5As shown, in this state, the two springs 2 36 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 1 21 to move downward. As the connecting plate 1 21 moves downward, the moving block 2 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 spring 2 36, the connecting rod 1 23 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. Under the limiting effect of the limiting groove 35, the electronic components that need to be crimped can be preliminarily positioned to ensure that the electronic components are located directly below the adsorption frame 17.

[0048] Then, if Figure 3 As shown, turn on the air pump 18 above the adsorption frame 17 and place the support leg inside the adsorption frame 17 . Under the action of the air pump 18 , the support leg can be fixed in the adsorption frame 17 .

[0049] like Figure 7 As shown, the electric push rod 20 is controlled to extend, driving the connecting plate 1 21 and the moving block 2 12 to move downward. At the same time, as the moving block 2 12 moves downward, under the hinged action of the hinged plate 24, the two moving blocks 1 29 will move toward each other in their corresponding rectangular notches 33, thereby allowing the two clamping plates 6 to move toward 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 1 29 continues to move, the spring 1 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 1 8, the electronic components on the top plate 7 waiting for the support leg crimping operation can be fixed.

[0050] 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 the 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 the support leg crimping during electronic component processing, and reducing the production of defective products.

[0051] 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 1 21 and the moving block 2 12 to move upward. First, under the hinged action of the hinged plate 24, the two moving blocks 1 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.

[0052] 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 support foot pressing operation, avoiding the problem of crimping failure or defective products, and improving the accuracy of the support 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 the upward movement of the top plate 7, which provides convenience for subsequent operators to take materials and improves the work efficiency during the crimping operation of the electronic component processing support feet. It is worthy of promotion and use.

[0053] Example 2, based on the above example:

[0054] 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 ;

[0055] The surface of the moving block 1 29 is fixedly connected to the 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.

[0056] A one-way valve 31 is provided on the surface of the air inlet pipe 32 , and a one-way valve 25 is provided on the surface of the air outlet pipe 38 .

[0057] In this embodiment, Figure 2 、 Figure 4 and Figure 6As shown, when the electric push rod 20 is controlled to retract, causing the two moving blocks 1 29 to move away from each other in their corresponding rectangular slots 33, the piston rod 27 will drive 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 electronic component support foot 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 inside the piston cylinder 26.

[0058] 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 will drive 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 air to clean the electronic components, thereby blowing off dust and impurities on the surface of the electronic components before the crimping operation, 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.

[0059] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
