Description

Technical Field

[0001] This utility model relates to the field of electronic component manufacturing technology, specifically to a resistor implantation and soldering device based on resistor integrated products. Background Technology

[0002] Integrated resistor products, such as surface mount resistor arrays and resistor network boards, are basic components widely used in modern electronic products. Their traditional manufacturing process usually includes multiple independent steps such as resistor implantation, soldering, cleaning, drying, and testing.

[0003] Currently, most manufacturing companies use single-machine operation or segmented semi-automatic production lines to complete these processes. First, operators manually or with special tooling insert the resistor elements into the predetermined positions on the substrate or frame. Then, the workpiece with the resistors inserted is transferred to a wave soldering machine or reflow soldering machine for soldering. After soldering, the workpiece needs to be cleaned with cleaning fluid to remove flux residue, and then sent to a drying oven for drying. Finally, the operator removes the workpiece and transfers it to a special electrical testing device for electrical parameter testing.

[0004] This traditional production method also has some drawbacks: frequent manual loading, unloading, and transfer between processes result in low production efficiency, high labor costs, and the inevitable placement errors caused by manual operation make it difficult to guarantee product consistency and yield. Based on this, a resistor implantation and soldering equipment based on resistor integrated products is proposed, which can seamlessly connect multiple processes such as resistor implantation, soldering, drying, and electrical testing to achieve one-stop automated production and solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a resistor implantation and soldering equipment for resistor integrated products, in order to solve the problems of low efficiency, low product yield and high labor costs caused by multiple processes being scattered during the production of resistor integrated products.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a resistor implantation and soldering equipment based on resistor integrated products, including three workbenches, a first workbench, a second workbench and a third workbench placed side by side, with a frame set on the left side of the first workbench; The frame is equipped with a vibrating feeding plate, the inner cavity of the first workbench is equipped with a resistance implantation module for feeding products, the inner cavity of the second workbench is equipped with a drying module, and the inner cavity of the third workbench is equipped with an electrical testing module. The resistor implantation module includes a support plate disposed in the inner cavity of the first workbench. The support plate is provided with a first electric push rod, a pusher, a clamping component, and a conveying component. The conveying component is disposed on one side of the clamping component and the conveying component. The drying module includes a drying cylinder and a conveyor belt disposed inside the drying cylinder, which is responsible for carrying and transporting the resistor array.

[0007] The above technical solution integrates resistor implantation, soldering, drying, and electrical testing processes into one, significantly improving the production efficiency and consistency of resistor integration products. The three workbenches are arranged side by side, shortening the material flow path and reducing the time required for intermediate handling. The vibrating feeding tray enables automatic supply of resistors, improving feeding efficiency. The cooperation between the electric push rod, pushing component, clamping component, and conveying component in the resistor implantation module realizes the clamping, implantation, and conveying of resistors. The drying module can perform uniform and stable drying of resistors in a closed environment, ensuring product quality. The electrical testing module facilitates direct electrical performance testing at the end of production, allowing for timely identification of good and defective products, forming a closed-loop production process.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the pushing component includes a mounting block fixed to the support plate, a second electric push rod fixed to the upper surface of the mounting block, and a movable plate fixed to the other end of the piston rod of the second electric push rod.

[0010] Through the above technical solution, the setting of the pusher can push the resistor on the vibrating feed plate into the clamping component.

[0011] Furthermore, a U-shaped block is fixed to the upper surface of the mounting block, and a groove is provided on the upper surface of the U-shaped block for the moving plate to slide horizontally. A photoelectric sensor is provided on the moving plate.

[0012] Through the above technical solution, the moving plate slides horizontally within the groove of the U-shaped block. The U-shaped structure provides good guidance and support, ensuring the smoothness of its horizontal sliding.

[0013] Furthermore, the clamping member includes a load-bearing plate fixed on the support plate, a No. 1 motor fixed on the top of the back of the load-bearing plate, the output shaft of the No. 1 motor passing through the load-bearing plate and extending to the front of the load-bearing plate and fixed with a rotating shaft, a rotating plate fixed on the outside of the rotating shaft, and an elliptical through hole opened on the rotating plate. The front of the load-bearing plate is fixed with a guide rail, and a slider is slidably connected to the guide rail. A movable plate is slidably connected to the front of the slider. A connecting rod is fixed to the top of the back of the movable plate. An arc-shaped groove is opened on the front of the load-bearing plate. The other end of the connecting rod passes through the through hole and extends into the inner cavity of the arc-shaped groove. A thumb cylinder is fixed on the front of the movable plate. An L-shaped clamping block is fixed on the opposite side of the two pneumatic fingers of the thumb cylinder.

[0014] The above technical solution uses a motor to drive a rotating shaft, which causes the rotating plate to rotate. The elliptical through hole on the rotating plate engages with the connecting rod, and under the constraint of the guide rail and the slider, the rotational motion is converted into the vertical movement of the movable plate, thereby allowing the clamping block to grip the resistor.

[0015] Furthermore, the rotating shaft and the load-bearing plate are rotatably connected by a bearing, and the connecting rod and the arc-shaped groove are inseparable.

[0016] The above technical solution ensures the stability of the rotating plate.

[0017] Furthermore, the conveying component includes a U-shaped seat fixed on the support plate. A screw is rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the U-shaped seat via a bearing. A second motor is fixed on the left side of the U-shaped seat, and the other end of its output shaft passes through the U-shaped seat and extends into the U-shaped seat and is fixed to the screw. A sliding block is threadedly connected to the outer surface of the screw. A fixed frame is fixed on the support plate. A slide rail is provided on the fixed frame. Multiple placement molds are evenly arranged in the slide rail. A partition is provided between two adjacent placement molds. The same linkage plate is fixed on the lower surface of the multiple partitions. The sliding block is fixed to the linkage plate.

[0018] The above technical solution uses a second motor to drive the screw to rotate. The cooperation between the sliding block and the screw causes the sliding block to make linear motion in the horizontal direction, thereby adjusting the moving position of the mold.

[0019] Furthermore, a No. 3 electric push rod is fixed in the middle of the inner bottom wall of the U-shaped seat, and an assembly block is fixed at the other end of the piston rod of the No. 3 electric push rod. Slide rails are fixed at both ends of the upper surface of the U-shaped seat, and connecting blocks are slidably connected to the upper surface of the slide rails. The connecting blocks are fixed to the linkage plate, and the same connecting plate is fixed to the upper surface of the two connecting blocks. The assembly block is fixed to the connecting plate.

[0020] Through the above technical solution, the slide rail, connecting block and connecting plate can adjust the horizontal position of the linkage plate, and then drive the movement of multiple partitions through the horizontal movement of the linkage plate.

[0021] Furthermore, a guide rail is fixed between the opposite sides of the left and right side walls of the inner cavity of the U-shaped seat, and guide blocks are fixed on both sides of the sliding block, with the guide blocks and guide rails slidably connected.

[0022] The above technical solution allows the sliding block to move horizontally as the screw rotates. By having two guide blocks slide on the outside of the guide rail, the movement of the sliding block can be limited, allowing it to move only in the horizontal direction.

[0023] Furthermore, a soldering component is provided on the support plate and on the rear side of the clamping component. The soldering component includes a bearing seat fixed on the support plate. A No. 3 motor is fixed on the upper surface of the bearing seat. A lead screw is rotatably connected between the opposite sides of the inner top wall and inner bottom wall of the bearing seat through a bearing. The output shaft of the No. 3 motor passes through and extends into the bearing seat and is fixed to the lead screw. A soldering head is threadedly connected to the outer surface of the lead screw.

[0024] By employing the above technical solution and using a motor-driven tin spraying method, the consistency of solder quantity and location for each product is ensured, significantly improving product quality and yield.

[0025] Furthermore, both the left and right sides of the support base are provided with protrusions, and the soldering head has a matching groove on the side facing the protrusion.

[0026] The above technical solution provides a limit to the movement direction of the soldering head by setting the protrusion and the corresponding groove, allowing it to move in the vertical direction.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: By integrating resistor implantation, soldering, drying, and electrical testing processes into one unit, the production efficiency and consistency of resistor integration products are significantly improved. The three workbenches are arranged side by side, shortening the material flow path and reducing the time required for intermediate handling. The vibrating feeding tray enables automatic supply of resistors, improving feeding efficiency. The electric push rod, pusher, clamping component, and conveyor in the resistor implantation module work together to clamp, implant, and convey resistors. The drying module can perform uniform and stable drying of resistors in a closed environment, ensuring product quality. The electrical testing module facilitates direct electrical performance testing at the end of the production process, allowing for timely identification of good and defective products, forming a closed-loop production process.

A drying module 7 is set inside the cavity of workbench 2. An electrical testing module 8 is set inside the cavity of workbench 3.

[0033] refer to Figure 3 , Figure 4 and Figure 5The resistor implantation module 6 includes a support plate 61 disposed in the inner cavity of the first workbench 1. The support plate 61 is provided with a first electric push rod 62, a pusher, a clamping member and a conveyor, and the conveyor is disposed on one side of the clamping member and the conveyor.

[0034] In this embodiment, the pushing component includes a mounting block 63 fixed on the support plate 61. A second electric push rod 64 is fixed on the upper surface of the mounting block 63. A moving plate 65 is fixed at the other end of the piston rod of the second electric push rod 64. The vibrating feeding plate 5 transports the resistors to the moving plate 65 in an orderly manner. The piston rod of the second electric push rod 64 drives the moving plate 65 to slide along the groove of the U-shaped block 66. At this time, the moving plate 65 can push the resistors into the clamping component.

[0035] Among them, a U-shaped block 66 is fixed on the upper surface of the mounting block 63. The upper surface of the U-shaped block 66 is provided with a sliding groove for the moving plate 65 to slide horizontally. The sliding groove on the U-shaped block 66 provides precise guidance for the movement of the moving plate 65. A photoelectric sensor is provided on the moving plate 65. The photoelectric sensor detects the position of the resistor and feeds the detection signal back to the control system.

[0036] In this embodiment, the clamping member includes a load-bearing plate 67 fixed on the support plate 61. A motor 68 is fixed to the top of the back side of the load-bearing plate 67. The output shaft of the motor 68 passes through the load-bearing plate 67 and extends to the front side of the load-bearing plate 67 and is fixed with a rotating shaft 69. A rotating plate 610 is fixed to the outside of the rotating shaft 69. An elliptical through hole 611 is opened on the rotating plate 610. A guide rail 632 is fixed to the front of the load-bearing plate 67. A slider 612 is slidably connected to the guide rail 632. A movable plate 613 is slidably connected to the front of the slider 612. A connecting rod 614 is fixed to the top of the back of the movable plate 613.

A thumb cylinder 616 is fixed to the front of the movable plate 613. An L-shaped clamping block 617 is fixed on the opposite side of the two pneumatic fingers of the thumb cylinder 616.

[0037] The rotating shaft 69 and the load-bearing plate 67 are rotatably connected by a bearing, and the connecting rod 614 and the arc groove 615 are inseparable.

[0038] Start motor 68. The output shaft of motor 68 rotates, driving the rotating shaft 69 and the rotating plate 610 fixed thereon to rotate. The through hole 611 on the rotating plate 610 rotates accordingly. The other end of the connecting rod 614 is located in the arc groove 615, so that it can only move along a predetermined trajectory. This drives the connecting rod 614 on the back of the movable plate 613 to move, causing the movable plate 613 to move downward under the guidance of the slider 612 and the guide rail 632. This drives the thumb cylinder 616 and the L-shaped clamping block 617 to move directly above the resistor to be clamped. Then, the thumb cylinder 616 drives the two L-shaped clamping blocks 617 to move towards each other to clamp the resistor. Then, motor 68 rotates in the opposite direction, driving the clamping component to carry the resistor away from the loading station and move to the placement mold 624 above the conveyor. The resistor is placed in the placement mold 624. Then, the conveyor starts and transports the mold with the resistor inserted to the next station.

[0039] In this embodiment, the conveying component includes a U-shaped seat 618 fixed on the support plate 61. A screw 619 is rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the U-shaped seat 618 via a bearing. A second motor 620 is fixed on the left side of the U-shaped seat 618, and the other end of its output shaft passes through the U-shaped seat 618 and extends into the U-shaped seat 618 and is fixed to the screw 619. A sliding block 621 is threadedly connected to the outer surface of the screw 619. A fixing frame 622 is fixed on the support plate 61. A slide 623 is provided on the fixing frame 622. Multiple placement molds 624 are evenly arranged in the slide 623. A partition 625 is provided between two adjacent placement molds 624. The same linkage plate 626 is fixed on the lower surface of the multiple partitions 625. The sliding block 621 is fixed to the linkage plate 626.

[0040] Among them, a No. 3 electric push rod 627 is fixed in the middle of the inner bottom wall of the U-shaped seat 618, and an assembly block 628 is fixed at the other end of the piston rod of the No. 3 electric push rod 627. Slide rails 629 are fixed at both ends of the upper surface of the U-shaped seat 618. A connecting block 630 is slidably connected to the upper surface of the slide rail 629. The connecting block 630 is fixed to the linkage plate 626. The same connecting plate 631 is fixed to the upper surface of the two connecting blocks 630. The assembly block 628 is fixed to the connecting plate 631.

[0041] In addition, a guide rail is fixed between the opposite sides of the left and right side walls of the inner cavity of the U-shaped seat 618, and guide blocks are fixed on both sides of the sliding block 621, with the guide blocks and guide rails being slidably connected.

[0042] After the resistor is placed into the placement mold 624, the second motor 620 is started. The output shaft of the second motor 620 rotates, driving the screw 619 to rotate, which in turn causes the sliding block 621 to move to the right on the outer surface of the screw 619. This causes the linkage plate 626 to move to the right. The movement of the linkage plate 626 causes multiple partitions 625 to push the placement mold 624 to move. Then, the third electric push rod 627 is started, which causes the assembly block 628 to move the connecting plate 631 and the connecting block 630. This causes the linkage plate 626 to move, which causes multiple partitions 625 to move a distance from two adjacent placement molds 624. This pushes the placement mold 624 onto the conveyor belt 72. Then, by starting the first electric push rod 62, the piston rod of the first electric push rod 62 pushes the placement mold 624 to move into the slide rail 623, thus enabling the placement mold 624 to be conveyed.

[0043] refer to Figure 2 The drying module 7 includes a drying cylinder 71 and a conveyor belt 72 disposed inside the drying cylinder 71, which is responsible for carrying and transporting the resistor group. The drying cylinder 71 is a drying chamber, which ensures that the heat is concentrated and evenly applied to the resistor group, significantly improving the drying efficiency. The built-in conveyor belt 72 is responsible for automatically carrying and transporting the resistor group, so that it can pass through the drying area smoothly and continuously.

[0044] refer to Figure 6 A soldering component is provided on the support plate 61 and located on the rear side of the clamping component. The soldering component includes a bearing seat 91 fixed on the support plate 61. A No. 3 motor 92 is fixed on the upper surface of the bearing seat 91. A lead screw 93 is rotatably connected between the inner top wall and the inner bottom wall of the bearing seat 91 through a bearing. The output shaft of the No. 3 motor 92 passes through and extends into the bearing seat 91 and is fixed to the lead screw 93. A solder spraying head 94 is threadedly connected to the outer surface of the lead screw 93.

[0045] The bearing base 91 has protrusions on both the left and right sides, and the soldering head 94 has a matching groove on the side facing the protrusion. The groove and protrusion can guide the movement of the soldering head 94, so that it can only move in a straight line.

[0046] In use, by starting motor 3 92, the output shaft of motor 3 92 rotates and drives lead screw 93 to rotate. The rotation of lead screw 93 causes the solder spray head 94 connected to it to move. At this time, the groove opened on the solder spray head 94 moves vertically under the limiting action of the protrusion. After the solder spray head 94 moves to the specified distance, the solder spraying process can be performed.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
