An equal distance spot welding device for electronic component processing

Abstract

The application discloses an equal-distance spot welding device for electronic component processing and belongs to the technical field of resistance welding. The device comprises a welding cabinet and a resistance welding mechanism installed in the welding cabinet. A component clamping assembly is connected to the bottom of the welding cabinet and corresponds to the resistance welding mechanism. A indentation assembly is connected to the top of the component clamping assembly and is used for rolling and pressing the component antenna to form a welding groove. In the application, the thinner antenna is located in the indentation on the surface of the thicker antenna, effectively increasing the contact surface, i.e. the welding surface, between the two resistance welding antennas. The contact surface is increased by changing the shape of the contact surface for welding, which not only optimizes the stress problem during welding, but also improves the welding quality and work efficiency. The resistance antenna indentation surface is cleaned to avoid the influence of impurities or dirt on the surface of the resistance on the welding quality, thereby ensuring good welding effect during welding and improving the welding quality.

Description

Technical Field

[0001] This invention belongs to the field of resistance welding technology and relates to an equidistant spot welding device for processing electronic components. Background Technology

[0002] Electronic components are the basic units that make up electronic devices. They come in a wide variety of types and have different functions, and are widely used in various fields such as communications, consumer electronics, automobiles, industrial control, and medical care.

[0003] Existing technologies disclose several invention patents in the field of resistance welding. Among them, patent CN108788425B discloses an electronic component spot welding mechanism and an electronic component spot welding device. The electronic component spot welding mechanism includes a transfer device, a pendulum-type flipping device, and a spot welding device. The transfer device includes a transfer support frame, a horizontal transfer plate, and a horizontal transfer drive unit. The pendulum-type flipping device includes a flipping drive unit, a flipping support frame, and a flipping plate. The spot welding device includes a spot welding support frame, a spot welding horizontal moving seat, a spot welding horizontal drive unit, a spot welding vertical lifting seat, a spot welding vertical drive unit, and a spot welding head. By setting up the transfer device, pendulum-type flipping device, and spot welding device, and optimizing the structure of each device, the electronic component spot welds all four sides, performing one spot weld on each side, thereby improving the spot welding efficiency. However, this technical solution still has some shortcomings in its application. When welding thin antennae to other thicker antennae or planes, the welding method is prone to deformation during welding due to the small diameter of the antennae, which makes them thinner and more prone to breakage. Using too small a welding force or parameters will result in insufficient welding quality, easy detachment of the solder joint, and low strength of the weld. It is also impossible to clean the surface dust, which can easily lead to poor welding during the welding process, such as weak welding, voids or cracks in the solder joint, which will affect the overall performance and stability of the electronic components.

[0004] Based on this, the present invention designs an equidistant spot welding device for processing electronic components to solve the above problems. Summary of the Invention

[0045] Please see the appendix Figure 1 -Appendix Figure 9 The present invention provides a technical solution: an equidistant spot welding device for processing electronic components, including a welding cabinet 1 and a resistance welding mechanism 2 installed inside the welding cabinet 1. A device clamping assembly 3 is connected to the bottom of the welding cabinet 1 corresponding to the resistance welding mechanism 2. An indentation assembly 4 is connected to the top of the device clamping assembly 3 for rolling the device contact to form a welding groove. A pressing assembly 6 is connected to the indentation assembly 4 for pushing the indentation assembly 4 in the opposite direction to roll the device contact.

[0046] Specifically, the device clamping assembly 3 includes a first linear module 301 and a second linear module 305 connected to the bottom of the welding cabinet 1. A first sliding seat 302 and a second sliding seat 306 are slidably connected to the two slides of the first linear module 301 and the second linear module 305, respectively. Clamping members 303 are connected to both the first sliding seat 302 and the second sliding seat 306, and the two clamping members 303 are symmetrically arranged. Push-pull members 304 are connected to the side of the two clamping members 303 that are far away from each other. The clamping member 303 includes a welding box 3032 connected to the top of the first sliding seat 302 or the second sliding seat 306. Multiple welding boxes 3032 are connected to the side end face of the welding box 3032, and the device contact is placed inside the welding box 3032.

[0047] The top of the welding box 3032 is provided with a first sliding groove 3033. Two first sliders 3034 are slidably connected within the first sliding groove 3033, corresponding to a single welding box 3032. The two first sliders 3034 are symmetrically arranged with respect to their respective welding boxes 3032. Each of the two first sliders 3034 has a clip 3035 connected to its top. The inner surface of each clip 3035 is connected with an anti-slip liner 3036. The push-pull component 304 includes a second housing 3041 connected to the side end face of the first housing 3031. The inner top wall of the second housing 3041 has a... Multiple second slide grooves are provided, each containing a second slider 3042. The bottom of each second slider 3042 is connected to a common push-pull plate 3043. The push-pull plate 3043 is connected to a first adapter 3044 corresponding to a first slider 3034. A push-pull rod 3045 is rotatably connected to the inner side of the other end of the first adapter 3044. A second adapter 3046 is rotatably connected to the other end of the push-pull rod 3045. The other end of the second adapter 3046 is connected to the bottom of the first slider 3034. Multiple resistors are respectively placed in multiple sets of clips 3. Within 035, the resistor body is located inside the clip 3035, and the resistor contact is located inside the solder box 3032. Turning the knob 3049 causes the threaded rod 3048 to rotate within the threaded cylinder 3047. Driven by the threaded rod 3048, the threaded cylinder 3047 drives the push-pull plate 3043 to slide within multiple second slide grooves via multiple second sliders 3042. The push-pull plate 3043 moves away from the resistor and pulls the push-pull rod 3045 through the first adapter 3044. The end of the push-pull rod 3045 rotates inside the first adapter 3044. The other end of the push-pull rod 3045 rotates inside the second adapter 3046 and generates a pulling force on the second adapter 3046. Under the pull of the two push-pull rods 3045, the two first sliders 3034 slide and converge in the first groove 3033, so that multiple resistors can be fixed at one time. The multiple resistors are arranged at equal intervals. By controlling the first linear module 301 and the second linear module 305, the multiple resistors are moved back and forth relative to the resistance welding mechanism 2, so that the resistance welding mechanism can perform equidistant spot welding on multiple sets of resistors.

[0048] A threaded rod 3048 is rotatably connected to the side end face of the second housing 3041. A threaded cylinder 3047 is threadedly connected to the other end of the threaded rod 3048. The threaded cylinder 3047 is snapped into the side end face of the push-pull plate 3043. A knob 3049 is connected to the other end of the threaded rod 3048. The indentation assembly 4 includes a base 401 connected to the side end faces of the two slide blocks. A third slide groove 402 is provided on the top of the base 401. A third slider 403 is slidably connected in the third slide groove 402. An indentation component is connected to the top of the third slider 403. 405, A hydraulic cylinder 404 is installed on the top of the base 401. The telescopic end of the hydraulic cylinder 404 is connected to the indentation component 405. The indentation component 405 includes a post 4051 connected to the top of the third slider 403. A fourth groove 4052 is opened on the side end face of the post 4051. A fourth slider 4053 is slidably connected in the fourth groove 4052. A first support spring 4054 is connected to the bottom of the fourth slider 4053. The fourth slider 4053 is elastically supported and connected to the bottom of the fourth groove 4052 through the fourth support spring.

[0049] The side end face of the fourth slider 4053 is connected to a lifting frame 4055. The bottom of the lifting frame 4055 is connected to multiple indentation seats 4056 corresponding to multiple welding grooves. The bottom of each of the multiple indentation seats 4056 is connected to an indentation wheel 4057.

[0050] The specific implementation method is as follows: After multiple pairs of resistors are clamped and fixed, the hydraulic cylinder 404 is controlled to extend. The hydraulic cylinder 404 pushes the pile 4051 to slide in the third slide groove 402 through the third slider 403. The pile 4051 drives the multiple indentation rollers 4057 connected to the lifting frame 4055 to move synchronously through the fourth slider 4053. During this process, the fourth slider 4053 drives the lower pressure roller 602 to roll on the lower pressure surface of the lower pressure plate 603 through the lifting rod 601. As the height of the lower pressure surface at the bottom of the lower pressure plate 603 gradually decreases, the lower pressure roller 602 moves through the lifting and lowering mechanism. Rod 601 presses down on the fourth slider 4053. The fourth slider 4053 slides downward in the fourth groove 4052 and squeezes the first support spring 4054 to cause it to deform elastically. Driven by the fourth slider 4053, the lifting frame 4055 presses down on the contacts of multiple resistors through multiple indentation wheels 4057. Indentations are left on the surface of the contacts. After the indentations are fully formed, the hydraulic cylinder 404 continues to push the column 4051. In subsequent stages, the height of the pressing surface at the bottom of the pressing plate 603 no longer changes, so that the same indentation marks can be left on the resistor contacts.

[0051] Specifically, the indentation seat 4056 is provided with a wiping component 5. The wiping component 5 includes a fifth slide groove 501 opened at the bottom of the indentation seat 4056. A fifth slider 502 is slidably connected in the fifth slide groove 501. A plurality of second support springs 503 are connected to the side end face of the fifth slider 502. The fifth slider 502 is elastically supported and connected to the inner wall of the fifth slide groove 501 through a plurality of third support springs.

[0052] The bottom of the fifth slider 502 is connected to the first wiping frame 504 and the second wiping frame 506 respectively. The inner side of the first wiping frame 504 is rotatably connected to a plurality of first wiping wheels 505, and the inner side of the bottom of the second wiping frame 506 is rotatably connected to a plurality of second wiping wheels 507.

[0053] The pressing assembly 6 includes a pressing plate 603 connected to the top of the base 401. A pressing wheel 602 is rolled on the pressing surface of the pressing plate 603. A lifting hole is opened in the fifth slide groove 501. A lifting rod 601 is sleeved in the lifting hole. The end of the lifting rod 601 is connected to the bottom of the pressing wheel 602. The other end of the lifting rod 601 is connected to the top of the fourth slider 4053.

[0054] A single push-pull assembly 8 is provided between multiple wiping components 5. The push-pull assembly 8 includes multiple support rods 801 respectively connected to the top of multiple fifth sliders 502. Each of the multiple fifth slide grooves 501 has a push-pull opening corresponding to the multiple support rods 801. The other end of the multiple support rods 801 is connected to the same main rod 802. A support plate is connected to the other end of the main rod 802 on the pile 4051. A gear 804 is rotatably connected to the support plate. A rocker arm 803 is rotatably connected to the top of the gear 804 off-center. The other end of the rocker arm 803 is rotatably connected to the inner side of the other end of the main rod 802. A toothed plate 805 connected to the top of the base 401 meshes with the tooth surface of the gear 804.

[0055] The specific implementation method is as follows: During the process of hydraulic cylinder 404 pushing post 4051, under the drive of multiple indentation seats 4056, the first wiping frame 504 drives multiple first wiping wheels 505 to move on the contact point, and the second wiping frame 506 drives multiple second wiping wheels 507 to move on the contact point, thereby cleaning the indentation on the resistor surface. The surfaces of the multiple first wiping wheels 505 are adsorbed with cleaning agent to clean the indentation on the contact point, and the multiple second wiping wheels 507 are used to adsorb residual cleaning agent to keep the indentation on the contact point surface dry. During this process, post 4051 drives gear 804 to roll on the tooth surface of tooth plate 805. 4. One end of the rocker arm 803 makes a circular motion. During this process, the end of the rocker arm 803 rotates on its own axis, and the other end rotates inside the end of the main rod 802, generating a pulling or pushing force on the end of the main rod 802. Under the action of continuous pushing and pulling forces, the main rod 802 pushes and pulls multiple fifth sliders 502 through multiple support rods 801 to slide in the fifth slide groove 501, thereby driving the first wiping wheel 505 and the second wiping wheel 507 to roll on the indentation surface. By utilizing the multiple movement modes of the first wiping wheel 505 and the second wiping wheel 507 on the indentation surface, the cleaning effect of the multiple first wiping wheels 505 on the indentation surface is effectively improved.

[0056] Specifically, a blower assembly 7 is provided between multiple indentation rollers 4057. The blower assembly 7 includes multiple first branch pipes 701 that are rotatably connected to the multiple indentation rollers 4057 respectively. The other end of the multiple first branch pipes 701 is connected to the same main pipe 702. A blower 703 is installed on the top of the base 401. The output port of the blower 703 is connected to the tail end of the main pipe 702.

[0057] The indentation wheel 4057 is also rotatably connected to a second branch pipe 704, the other end of which is connected to a diversion pipe, and the remaining ports of the diversion pipe are rotatably connected to multiple second wiping wheels 507 respectively.

[0058] The specific implementation method is as follows: An electric heater is installed inside the indentation roller 4057. During the process of multiple second wiping rollers 507 wiping the indentation surface, the blower 703 is controlled to run. The blower 703 inputs gas into multiple first branch pipes 701 through the main pipe 702. Multiple streams of gas enter multiple indentation rollers 4057 respectively. After the gas enters the indentation roller 4057, it will be heated. The heated gas enters the second wiping roller 507 through the second branch pipe 704 to heat the second wiping roller 507.

[0059] Working principle and usage:

[0060] Multiple resistors with thicker antennae are placed into multiple sets of clips 3035 located on the left side. Each set of clips 3035 consists of two clips 3035 corresponding to a single solder box 3032. Then, multiple resistors with relatively thinner antennae are placed into multiple sets of clips 3035 located on the right side.

[0061] Multiple resistors are placed into multiple sets of clips 3035, with the resistor bodies inside the clips 3035 and the resistor contacts inside the soldering box 3032. Turning the knob 3049 rotates the threaded rod 3048 within the threaded cylinder 3047. Driven by the threaded rod 3048, the threaded cylinder 3047 drives the push-pull plate 3043 to slide through multiple second sliders 3042 within multiple second grooves. The push-pull plate 3043 moves away from the resistors and pulls the push-pull rod 3045 through the first adapter 3044. The end of the push-pull rod 3045 is connected to the first adapter 3044. The inner side of 044 rotates, and the other end of the push-pull rod 3045 rotates inside the second adapter 3046, generating a pulling force on the second adapter 3046. Under the pull of the two push-pull rods 3045, the two first sliders 3034 slide and converge in the first slide groove 3033, thereby enabling the clamping and fixing of multiple resistors at one time. The multiple resistors are arranged at equal intervals. By controlling the first linear module 301 and the second linear module 305, the multiple resistors are moved back and forth relative to the resistance welding mechanism 2, so that the resistance welding mechanism can perform equidistant spot welding on multiple sets of resistors.

[0062] After multiple pairs of resistors are clamped and fixed, the hydraulic cylinder 404 is controlled to extend. The hydraulic cylinder 404 pushes the pile 4051 to slide in the third slide groove 402 via the third slider 403. The pile 4051 drives the multiple indentation rollers 4057 connected to the lifting frame 4055 to move synchronously via the fourth slider 4053. During this process, the fourth slider 4053 drives the lower pressure roller 602 to roll on the lower pressure surface of the lower pressure plate 603 via the lifting rod 601. As the height of the lower pressure surface at the bottom of the lower pressure plate 603 gradually decreases, the lower pressure roller 602 moves via the lifting rod 601. The fourth slider 4053 is pressed down and slides downward in the fourth groove 4052, squeezing the first support spring 4054 to cause it to deform elastically. Driven by the fourth slider 4053, the lifting frame 4055 presses down on the contacts of multiple resistors through multiple indentation wheels 4057, leaving indentations on the contact surfaces. After the indentations are fully formed, the hydraulic cylinder 404 continues to push the column 4051. In subsequent stages, the height of the pressing surface at the bottom of the pressing plate 603 no longer changes, thus leaving the same indentation marks on the resistor contacts.

[0063] During the process of hydraulic cylinder 404 pushing post 4051, driven by multiple indentation seats 4056, the first wiping frame 504 drives multiple first wiping wheels 505 to move on the contact point, and the second wiping frame 506 drives multiple second wiping wheels 507 to move on the contact point, thereby cleaning the indentations on the resistor surface. The surfaces of the multiple first wiping wheels 505 are adsorbed with cleaning agent to clean the indentations on the contact point, and the multiple second wiping wheels 507 are used to adsorb residual cleaning agent to keep the indentations on the contact point surface dry. During this process, post 4051 drives gear 804 to roll on the tooth surface of gear plate 805, and gear 804 drives one end of rocker arm 803 to perform a circular motion. During this process, the end of the rocker arm 803 rotates, and the other end rotates inside the end of the main rod 802, generating a pulling or pushing force on the end of the main rod 802. Under the action of continuous pushing and pulling forces, the main rod 802 pushes and pulls multiple fifth sliders 502 through multiple support rods 801 to slide in the fifth slide groove 501, thereby driving the first wiping wheel 505 and the second wiping wheel 507 to roll on the indentation surface. By utilizing the multiple movement modes of the first wiping wheel 505 and the second wiping wheel 507 on the indentation surface, the cleaning effect of the multiple first wiping wheels 505 on the indentation surface is effectively improved, and the drying effect of the multiple second wiping wheels 507 on the indentation surface is enhanced.

[0064] An electric heater is installed inside the indentation roller 4057. During the process of multiple second wiping rollers 507 wiping the indentation surface, the blower 703 is controlled to run. The blower 703 inputs gas into multiple first branch pipes 701 through the main pipe 702. Multiple streams of gas enter multiple indentation rollers 4057 respectively. After entering the indentation roller 4057, the gas is heated. The heated gas enters the second wiping roller 507 through the second branch pipe 704 to heat the second wiping roller 507, which helps to improve the wiping effect of the second wiping roller 507.

[0065] Indentations are left on the thicker antennae. Electric push rods are installed on the first sliding seat 302 and the second sliding seat 306, respectively. These electric push rods control the two clamping members 303 to move closer together until the welding boxes 3032 on both sides are fully aligned. The antennae overlap on the outer part of the welding box 3032, with the thinner antennae located within the indentations on the surface of the thicker antennae. Descriptions of the structural orientation and relative positional relationships in this invention, such as descriptions of front, back, left, right, up, and down, do not constitute limitations on the invention and are merely for descriptive convenience.
