Description

Technical Field

[0001] The invention relates to the technical field of workpiece bending, and in particular to a workpiece rapid bending device. Background Art

[0002] Electronic components are the basic units that make up electronic devices. They can be used alone or combined to form more complex circuits or systems. Electronic components mainly include passive components: capacitors, resistors, etc.; active components: diodes, transistors, etc. Most electronic components have metal contact points, i.e. pins, for electrical connection with other circuit components or systems. During the processing and assembly of electronic components, the pins need to be bent as required in order to better fix the components and correctly install them on the circuit board or other carriers. Bending is an important operation step, especially for those electronic components that use through-hole insertion technology.

[0003] Existing pin bending generally adopts mechanical bending. When bending, the component with pins is first placed on the base, so that the pins to be bent extend out of the base, and then the component body is fixed, and the suspended part of the pin is stamped and bent by moving the bending head downward. However, the above bending method still has the following shortcomings: 1. During the bending process, the bending stress will be more or less transmitted to the component through the root of the pin, which is easy to affect the connection quality of the connection between the pin and the component, and then affect the use of the component; 2. When the pin is bent by moving the bending head vertically downward, the bending head slides close to the surface of the pin, and the plating on the surface of the pin is easily damaged by friction, which will affect the quality of the pin; 3. After the pin is bent into a 90-degree L shape, if the component body simultaneously contacts the side of the base, the pin and the component will be stuck on the base as a whole, which will affect the material cutting efficiency of the component.

[0016] The beneficial effects of the present invention are as follows: 1. The present invention arranges a pin pressing block at the front end of the lower pressing plate. When the lower pressing plate presses the components, the pin pressing block and the horizontal section at the top of the C-shaped plate cooperate to simultaneously clamp and fix the non-bending part of the pin, thereby improving the stability of the pin during bending, avoiding additional deformation of the non-bending part of the pin, and avoiding affecting the connection between the pin and the component, which is beneficial to improving the quality of the bending of the component.

[0017] 2. The present invention uses a bending plate to rotationally bend the pin. After the pressing assembly pushes the pressing plate downward to press the components, the pressing assembly can continue to move downward and drive the driving assembly to operate. Then the driving assembly drives the bending plate to rotationally bend the pin. The bending plate rotates with the pin to avoid slipping along the surface of the pin, preventing the coating on the surface of the pin from being damaged by friction, thereby further improving the bending quality of the pin.

In the present invention, when the driving assembly drives the bending plate to rotate to bend the pin, the driving assembly can also move the C-shaped plate forward to be flush with the front side of the support block, and use the C-shaped plate to support the pin to ensure that the pin is bent ninety degrees on the surface of the C-shaped plate. After the bending is completed, the driving assembly drives the bending plate to reset upward and cancels the front support of the C-shaped plate, so that the C-shaped plate moves backward under the pull of the reset spring, avoiding the pin from being stuck and facilitating the unloading of components.

[0019] 4. The present invention utilizes a blanking mechanism to unload components. When the lower pressure plate presses the components, the material guide assembly can clamp the components. When the lower pressure plate moves upward to reset, the material guide assembly can drive the components to move upward together and out of the bending station. At the same time, the upward lower pressure plate can also pull the blanking plate to the left to the bottom of the lower pressure plate. When the lower pressure plate moves to the triangular bevel block, the triangular bevel block is used to push the blanking clamp to release the clamping of the components, so that the components fall onto the blanking plate and then slide into the collection box, which is convenient for automatic unloading.

[0035] See also Figure 1 , Figure 2 and Figure 3 The feeding mechanism 3 includes a pulley 31 rotatably mounted on the front side of the mounting plate 1 and distributed on the left and right sides of the bending station 2. A conveyor belt 32 is transmission-connected between the outsides of the two pulleys 31. The top conveyor belt 32 passes through the bending station 2. A support plate 33 for supporting the top of the conveyor belt 32 is fixedly connected to the front side of the mounting plate 1. A groove wheel assembly 34 is rotatably mounted on the rear side of the mounting plate 1. The drive motor 7 is transmission-connected to the pulley 31 on the right side through the groove wheel assembly 34.

[0036] The driving motor 7 drives the pulley 31 on the right to rotate intermittently through the groove wheel assembly 34, and then the pulley 31 drives the conveyor belt 32 to rotate clockwise, so that the conveyor belt 32 gradually moves the components to be bent to the right, and transports the components one by one to the bending station 2 for bending.

[0037] See also Figure 1 , Figure 2 and Figure 4The lower pressing assembly 44 includes a guide frame 441 fixedly connected to the top of the mounting plate 1, an upper pressing plate 442 is slidably installed on the front side of the guide frame 441, and the bottom of the upper pressing plate 442 is fixedly connected to the top of the lower pressing plate 41 through a fixedly connected first elastic telescopic rod 443, and the up and down moving mechanism 5 includes a central axis 51 rotatably installed on the top of the guide frame 441, a turntable 52 is coaxially fixedly connected to the front side of the central axis 51, and a connecting rod 53 is rotatably connected to the edge of the front side of the turntable 52, and the lower end of the connecting rod 53 is rotatably connected to the top of the upper pressing plate 442, and the driving motor 7 and the central axis 51 are connected by a belt drive.

[0038] The central axis 51 and the turntable 52 are driven to rotate by the driving motor 7, and then the turntable 52 drives the upper pressure plate 442 to move reciprocatingly up and down through the connecting rod 53. When the upper pressure plate 442 moves downward, the upper pressure plate 442 pushes the lower pressure plate 41 to move downward and press on the components through the first elastic telescopic rod 443 to fix the components. At the same time, the pin pressing block 42 at the front end of the lower pressure plate 41 can be pressed on the non-bending part of the pin, thereby improving the stability of the pin when bending, preventing stress from being transferred from the root of the pin to the component, avoiding additional deformation of the non-bending part of the pin, and avoiding affecting the connection between the pin and the component.

[0039] See also Figure 5 , Figure 6 , Figure 7 and Figure 8 A baffle 621 is fixedly connected to the rear side of the horizontal section at the bottom of the U-shaped plate 62, a baffle groove 622 is opened inside the support block 61, the baffle 621 is slidably installed inside the baffle groove 622, and a return spring 623 is fixedly connected between the rear side of the vertical section of the U-shaped plate 62 and the support block 61.

[0040] After the pin is bent, the C-shaped plate 62 is controlled to move backward and compress the return spring 623, so that the vertical section of the C-shaped plate 62 is away from the bending section of the pin, so that the pin can be quickly unloaded after bending. The retaining groove 622 is used to limit the baffle 621 and control the forward and backward movement of the C-shaped plate 62, so that the C-shaped plate 62 can be flush with the front side of the support block 61 when moving forward, which is convenient for the C-shaped plate 62 to support the pin and ensure accurate bending of the pin.

[0041] Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9The driving assembly 64 includes a guide rail 641 which is symmetrically fixedly installed on the support block 61, a slider 642 is installed inside the guide rail 641 for sliding up and down movement, a return spring 2 643 is fixedly connected between the bottom of the slider 642 and the inner bottom wall of the guide rail 641, a rack 644 is fixedly connected to the front side of the slider 642, and gears 645 are coaxially fixedly connected to the left and right sides of the bending plate 63, and the gears 645 are meshed with the corresponding racks 644, a wedge block 1 646 is fixedly connected to the side of the slider 642 close to the center of the support block 61, and the rear end of the bottom inclined surface of the wedge block 1 646 is inclined downward, and a wedge block 2 647 is fixedly connected to the rear side of the shaped plate 62 symmetrically, and the rear end of the top inclined surface of the wedge block 2 647 is inclined downward, and the wedge block 1 646 cooperates with the corresponding wedge block 2 647.

[0042] After the upper pressure plate 442 pushes the lower pressure plate 41 downward to press the component, the upper pressure plate 442 continues to move downward, and the upper pressure plate 442 pushes the rack 644 downward, and the rack 644 drives the gear 645 to rotate, and then the gear 645 drives the bending plate 63 to rotate downward to bend the pin. Before the bending plate 63 contacts the pin, the downward-moving rack 644 pushes the slider 642 to move downward, and then the slider 642 drives the wedge block 1 646 to move downward, and the inclined surfaces of the wedge block 1 646 and the wedge block 2 647 cooperate to push the wedge block 2 647 and the C-shaped plate 62 to move forward, and then the wedge block 1 646 will slide downward along the vertical section on the rear side of the wedge block 2 647, keeping the C-shaped plate 62 flush with the front side of the support block 61, and then the bending plate 63 contacts the pin to bend it, so that the pin can be bent ninety degrees and fit to the surface of the C-shaped plate 62.

[0043] See also Figure 2 , Figure 5 and Figure 6 The movable component 66 includes a slide 661 fixedly mounted on the front side of the mounting plate 1, a slide seat 662 is slidably mounted on the top of the slide 661, a return spring 663 is fixedly connected between the front side of the slide seat 662 and the front end of the slide 661, a cam 664 located on the rear side of the slide seat 662 is rotatably mounted on the rear end of the slide 661, a transmission rod 665 is rotatably mounted on the mounting plate 1, the transmission rod 665 is transmission-connected to the cam 664 through a bevel gear set, and the drive motor 7 is connected to the transmission rod 665 through a belt transmission.

[0044] The transmission rod 665 is driven to rotate by the driving motor 7, and then the transmission rod 665 drives the cam 664 to rotate, so that the cam 664 pushes the slide 662 to move forward and backward periodically, and the slide 662 drives the support block 61, the bending plate 63 and the driving assembly 64 to move forward to avoid the bending plate 63 and the rack 644 from blocking the pins, so as to facilitate the movement of components to the bending station 2, and then the rebound force of the reset spring three 663 is used to push the slide 662 to move backward for reset.

[0045] See also Figure 4 , Figure 5 and Figure 6 The adjustment component 65 includes a slide groove 651 opened on the top of the slide seat 662, and the support block 61 is installed inside the slide groove 651 for sliding back and forth. A screw 652 is rotatably installed inside the slide groove 651. The screw 652 is threadedly connected to the support block 61. The front end of the screw 652 extends to the front of the slide seat 662 and is fixedly connected to a hand wheel 653.

[0046] By rotating the handwheel 653 to drive the lead screw 652 to rotate, the support block 61 can be moved forward and backward along the slide groove 651, which is convenient for adjusting the distance between the top horizontal section of the C-shaped plate 62 and the mounting plate 1, and then the pin pressing block 42 is moved synchronously to adjust its front and rear position. After adjustment, the pin pressing block 42 is pressed and fixed by rotating the fixing bolt 43 to move it downward, and the pin is fixed by using the pin pressing block 42 and the C-shaped plate 62, which is convenient for bending the pin to different lengths.

[0047] See also Figure 1 , Figure 2 and Figure 4 The material discharge mechanism 8 includes a material guide assembly 81 installed on the upper side and located on the right side of the bending station 2 , a clamping assembly 82 is installed on the lower pressing plate 41 , and a collection box 83 is arranged below the right end of the material guide assembly 81 .

[0048] See also Figure 1 and Figure 2 The material guide assembly 81 includes an inclined groove 811 opened on the mounting plate 1, the right end of the inclined groove 811 is inclined downward, and a discharge plate 812 with a right end inclined downward is arranged at the front end of the mounting plate 1. The discharge plate 812 slides along the length direction of the inclined groove 811, and the front end of the mounting plate 1 is fixedly connected with a fixed plate 813 located below the discharge plate 812. A return spring 814 is fixedly connected between the left side of the fixed plate 813 and the bottom of the discharge plate 812, and the rear side of the upper pressure plate 442 is fixedly connected to the discharge plate 812 through a fixedly connected pull rope 815.

[0049] See also Figure 4 and Fig.10The clamping assembly 82 includes a through slot 821 opened on the left and right sides of the lower pressure plate 41, and the interior of the through slot 821 is fixedly connected to a shaft rod 822, and a blanking clamp 823 is rotatably installed on the outside of the shaft rod 822. The bottom end of the blanking clamp 823 is provided with an inclined hook, and the end of the inclined hook close to the center of the lower pressure plate 41 is inclined upward. The outside of the shaft rod 822 is also provided with a torsion spring 824 for driving the bottom end of the blanking clamp 823 to move toward the middle of the lower pressure plate 41. The front end of the guide frame 441 is fixedly connected to a triangular inclined block 825 that cooperates with the blanking clamp 823. The triangular inclined block 825 is a right triangle, and the top of the inclined surface is inclined toward the center of the guide frame 441.

[0050] When the lower pressing plate 41 presses the component, the distance between the lowest points of the two oblique hooks is slightly larger than the width of the component, and the oblique sides of the oblique hooks fit the top of the left and right sides of the component. As the lower pressing plate 41 drives the blanking clamp 823 to move downward, the oblique hook and the corresponding guiding blanking clamp 823 rotate outward as a whole under the driving force from the component, and finally contact the left and right sides of the component. At the same time, under the torsional force of the torsion spring 824, the two oblique hooks respectively press the left and right sides of the component to clamp the component. When the lower pressing plate 41 moves upward to reset, the blanking clamp 823 can drive the component to move upward together and leave the bending process. Position 2, and at the same time, the upwardly moved upper pressure plate 442 can also pull the unloading plate 812 to the left to the bottom of the lower pressure plate 41 through the pull rope 815. When the lower pressure plate 41 moves to the triangular bevel block 825, the inclined surface of the triangular bevel block 825 is used to push the upper end of the unloading clamp 823 to deflect toward the center of the guide frame 441, so that the lower end of the unloading clamp 823 releases the clamping of the components, and then the components fall onto the unloading plate 812 and slide into the collection box 83, which is convenient for automatic unloading. When the lower pressure plate 41 moves downward, the return spring four 814 can pull the unloading plate 812 to move to the right and away from the bottom of the lower pressure plate 41.

[0051] See also Figure 1-Figure 10 When used specifically, step one is to rotate the hand wheel 653 to drive the lead screw 652 to rotate, so that the support block 61 can move forward and backward along the slide groove 651, adjust the distance between the top horizontal section of the U-shaped plate 62 and the bending station 2, and then loosen the fixing bolt 43, and then adjust the front and rear position of the pin pressing block 42 so that the pin pressing block 42 is directly above the U-shaped plate 62, and then tighten the fixing bolt 43 to fix the pin pressing block 42.

[0052] Step 2: Drive the transmission rod 665 to rotate through the driving motor 7, and then the transmission rod 665 drives the cam 664 to rotate, so that the cam 664 pushes the slide 662 to move forward periodically, and the slide 662 drives the support block 61, the bending plate 63 and the driving assembly 64 to move forward to avoid the bending plate 63 and the rack 644 from blocking the pin.

[0053] Step three, the driving motor 7 drives the pulley 31 on the right side to rotate intermittently through the groove wheel assembly 34, and then the pulley 31 drives the conveyor belt 32 to rotate clockwise, so that the conveyor belt 32 moves the components to be bent to the right step by step, and conveys the components one by one to the bending station 2. After that, the protrusion of the cam 664 moves away from the slide 662, and the reset spring three 663 is used to push the slide 662 to move backward, so that the slide 662 can move backward and reset, and move the bending plate 63 to the top of the pin.

[0054] Step 4, drive the central axis 51 and the turntable 52 to rotate through the driving motor 7, and then the turntable 52 drives the upper pressure plate 442 to move reciprocatingly up and down through the connecting rod 53. When the upper pressure plate 442 moves downward, the upper pressure plate 442 pushes the lower pressure plate 41 to move downward and press it onto the components through the first elastic telescopic rod 443 to fix the components. At the same time, the pin pressing block 42 at the front end of the lower pressure plate 41 can be pressed onto the pin to improve the stability of the pin when bending. In the process of the lower pressure plate 41 pressing the component, the beveled edge of the bevel hook will guide the blanking clamp 823 to open and clamp it on the left and right sides of the component.

[0055] Step 5. After the upper pressure plate 442 pushes the lower pressure plate 41 downward to press the components, the upper pressure plate 442 continues to move downward, and the rack 644 is pushed downward by the upper pressure plate 442. The downwardly moved rack 644 drives the slider 642 to move downward, and then the slider 642 drives the wedge block 1 646 to move downward, and the wedge block 1 646 is used to push the wedge block 2 647 and the C-shaped plate 62 forward, so that the C-shaped plate 62 is flush with the front side of the support block 61, and then the rack 644 is used to drive the gear 645 to rotate, and then the gear 645 drives the bending plate 63 to rotate downward to bend the pin 90 degrees, so that the pin fits the surface of the C-shaped plate 62.

[0056] Step 6. The rotating turntable 52 then drives the upper pressure plate 442 to move upward through the connecting rod 53, so that the upper pressure plate 442 no longer presses the rack 644. At this time, the slider 642 is pushed to move upward through the reset spring 2 643, and then the slider 642 drives the rack 644 and the wedge block 1 646 to move upward, and the rack 644 drives the gear 645 to rotate in the opposite direction, so that the bending plate 63 rotates upward in the opposite direction and resets, and then the wedge block 1 646 moves to the top of the wedge block 2 647, and then the reset spring 1 623 is used to pull the C-shaped plate 62 backward to prevent the C-shaped plate 62 from being stuck in the pin.

[0057] Step seven, when the first elastic telescopic rod 443 returns to its original length, the upper pressure plate 442 pulls the lower pressure plate 41 upward through the first elastic telescopic rod 443, so that the lower pressure plate 41 and the pin pressing block 42 release the fixation of the components and pins, and at the same time, the lower pressure plate 41 drives the components to move upward and out of the bending station 2 through the blanking clamp 823. At the same time, the upward lower pressure plate 41 can also pull the blanking plate 812 to the left to the bottom of the lower pressure plate 41 through the pull rope 815. When the lower pressure plate 41 moves to the pull rope 815, the inclined surface of the triangular inclined block 825 is used to push the upper end of the blanking clamp 823 to deflect toward the center of the guide frame 441, so that the lower end of the blanking clamp 823 releases the clamping of the LED, and then the LED falls onto the blanking plate 812, so that the components slide along the blanking plate 812 into the collection box 83.

[0058] Step 8. Repeat steps 2 to 7 to bend the pins of subsequent components.
