Description

A multi-station chip pin synchronous bending device Technical Field

[0001] This utility model relates to the field of electronic manufacturing, and in particular to a multi-station chip pin synchronous bending device. Background Technology

[0002] In the electronics manufacturing industry, chips are core components, and their pin bending process is a crucial step in the production process. As electronic products become increasingly miniaturized and integrated, the requirements for chip pin bending accuracy and production efficiency are constantly increasing. Traditional chip pin bending equipment is mostly single-station operation, resulting in low production efficiency and difficulty in meeting the needs of large-scale production. Some multi-station equipment lacks an effective synchronous control mechanism, leading to poor coordination between stations, resulting in inconsistent bending angles and forces, severely affecting the bending quality of chip pins and product yield. Furthermore, existing equipment has low automation in the demolding and unloading stages, requiring frequent manual intervention, which not only increases labor costs but also easily introduces human error, reducing production efficiency. Therefore, developing a multi-station synchronous pin bending device is of great significance for improving chip production quality and efficiency and promoting the development of the electronics manufacturing industry. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology that cannot achieve synchronous pin bending at multiple workstations, the technical problem of this utility model is to provide a device for synchronous bending of chip pins at multiple workstations.

[0004] The technical solution is as follows: A multi-station chip pin synchronous bending device includes a bending machine. The bending machine has two symmetrically distributed working areas as stations. A cylinder is installed at the top of each station, with its piston rod pointing vertically downwards and its end fixedly connected to a bending block. T-shaped placement blocks are respectively provided on the operating planes of the two stations. These placement blocks are slidably connected to rectangular grooves on the bending machine via sliders at their bottoms, ensuring smooth movement of the placement blocks during bending. At each of the two stations, two symmetrically vertically positioned limit rods are arranged with the station center as a reference. The tops of the two limit rods pass parallel upwards through two corresponding guide holes on the bending block and slide in cooperation with them. Inside the bending block, a spring mounting cavity is provided corresponding to the top of the limit rods. The inner diameter of the spring is larger than its outer diameter, and its depth can accommodate the maximum compression stroke of the spring. One end of the spring is fixedly connected to the middle of the limit rod. The other end of the spring is fixed to the top of the spring mounting cavity. The structure formed by the limiting rod and the spring plays a guiding and buffering role during the bending process and provides power for demolding. Inside the bending machine, V-shaped top blocks are symmetrically rotated and connected to each station. One inclined surface of the top block contacts the bottom of the placement block, and the other inclined surface of the top block contacts the bottom of the limiting rod. When the cylinder pushes the bending block down, the bending block presses down on the chip pins on the placement block. After being subjected to force in the vertical direction, the placement block slides downward, and its bottom... The top block is pressed on one side of the inclined surface, causing it to rotate around the pivot. Simultaneously, the other side of the top block is raised and presses the bottom of the limiting rod. The limiting rod is pushed up, and the top spring is compressed to store energy. When the cylinder rises and drives the bending block to reset, the spring releases its elastic force and pushes the limiting rod downward. The limiting rod presses the other side of the top block's inclined surface, causing the top block to rotate in the opposite direction. One side of the top block's inclined surface pushes the placement block upward. At the same time, the elastic ejector pin structure set on the top of the placement block pops out when the placement block rises, pushing the chip off the placement block.

[0005] More preferably, it also includes electric push rods. On each of the two stations of the bending machine, electric push rods are arranged horizontally in a centrally symmetrical manner with the center of the station as the reference. The telescopic rod of the electric push rod faces horizontally outward from the station. The end of the telescopic rod of the electric push rod is fixedly connected to a discharge block. The discharge block is fixed vertically to the telescopic rod and parallel to the station plane, and is used to contact the side of the chip and smoothly push the chip out. A cuboid collection box is placed on the front side of the bending machine. The width of the collection box is greater than the total width of the two stations. The opening of the collection box faces the pushing direction of the discharge block, so that the chip can slide smoothly into the collection box.

[0006] More preferably, it also includes a handle, with a handle fixedly connected to the front side of the collection box, the handle being used to facilitate the taking of the collection box.

[0007] More preferably, it also includes protective plates, which are symmetrically fixed to the left and right sides of the bending machine to prevent foreign objects from entering the bending machine.

[0008] More preferably, it also includes a buffer pad, which is fixedly connected to the bottom of the collection box to prevent damage when the chips are stacked.

[0009] More preferably, it also includes baffles, with baffles symmetrically fixedly connected to both the left and right sides of the discharge block to prevent the chip from slipping to the sides during the chip ejection process.

[0010] Compared with the prior art, the present invention has the following advantages: 1. The bending block is driven by the cylinder to press down the chip pin. When the placement block slides down under force, it squeezes the top block. The top block rotates and pushes the limit rod to rise, compressing the spring to store energy. After bending is completed, the spring releases energy and pushes the limit rod, causing the top block to rotate in the opposite direction and lift the placement block. The combination of the limit rod and the spring guides and buffers during bending, providing power for demolding. All components work together to realize multi-station bending and demolding of the chip pin.

[0011] 2. When the telescopic rod extends, it drives the discharge block to move horizontally. The discharge block contacts the side of the chip and pushes the chip out smoothly, sliding it into the rectangular collection box at the front of the bending machine. The buffer pad at the bottom of the collection box prevents the chips from being stacked and damaged, realizing automated chip discharge and safe collection.

[0012] 3. The protective plate prevents foreign objects from entering the bending machine and protects the normal operation of the equipment. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Example: A multi-station chip pin synchronous bending device, as shown in Figures 1-3, includes a bending machine 1, a cylinder 2, a bending block 3, a placement block 4, limiting rods 5, a spring 6, and a top block 7. The bending machine 1 has two symmetrically distributed working areas as stations. A cylinder 2 is installed at the top of each station, with its piston rod pointing vertically downwards and its end fixedly connected to the bending block 3. T-shaped placement blocks 4 are respectively provided on the operating planes of the two stations of the bending machine 1. At each of the two stations of the bending machine 1, two limiting rods 5 are symmetrically and vertically arranged with the station center as a reference. The tops of the two limiting rods 5 pass parallel upwards through two corresponding guide holes on the bending block 3 and slide in cooperation with them. Inside the bending block 3, a spring mounting cavity is provided corresponding to the top position of the limiting rod 5. The mounting cavity is inside the bending block 3. One end of the spring 6 is fixedly connected to the middle of the limiting rod 5, and the other end of the spring 6 is fixed to the top of the spring 6 mounting cavity. Inside the bending machine 1, a V-shaped top block 7 is symmetrically rotatably connected to each station. One side of the inclined surface of the top block 7 contacts the bottom of the placement block 4, and the other side of the inclined surface contacts the bottom of the limiting rod 5. When the cylinder 2 pushes the bending block 3 down, the bending block 3 presses down on the chip pin on the placement block 4. After being subjected to force in the vertical direction, the placement block 4 slides down, and its bottom presses against one side of the inclined surface of the top block 7, causing the top block 7 to rotate around the axis.

[0019] Power on the equipment and turn on the control system. Ensure all components are in normal standby mode. Place the chip with the pins to be bent onto the placement blocks 4 at the two workstations, ensuring the chips are placed stably and accurately. The operator issues a bending command through the control system. Under the precise control of the synchronous control system, the piston rods of the cylinders 2 at the top of the two workstations extend vertically downwards synchronously. Since the bending block 3 is fixedly connected to the end of the cylinder 2, the movement of the cylinder 2 causes the bending block 3 to descend. The descending bending block 3 presses down on the chip pins placed on the placement blocks 4, causing the chip pins to bend. Simultaneously, the placement block 4 is subjected to vertical force and slides downwards in the rectangular groove of the bending machine 1 via a slider at its bottom. During the downward movement of the placement block 4, its bottom presses against one inclined surface of the V-shaped top block 7, causing the top block 7 to rotate around the axis. As the top block 7 rotates, the other inclined surface rises synchronously, pressing against the bottom of the limiting rod 5 and pushing the limiting rod 5 upwards. During the upward movement of the limiting rod 5, it compresses the spring 6, which is sleeved on top of the limiting rod and located within the mounting cavity of the spring 6, allowing the spring 6 to store energy. The inner diameter of the mounting cavity of the spring 6 is slightly larger than the outer diameter of the spring 6, and its depth can accommodate the maximum compression stroke of the spring 6, ensuring normal compression of the spring 6. During this process, the structure formed by the limiting rod 5 and the spring 6 plays a guiding and buffering role, ensuring the stability of the bending process. After the chip pin is bent, the control system issues a command, the piston rod of the cylinder 2 rises, driving the bending block 3 to reset, and the spring 6 releases the previously stored elastic force, pushing the limiting rod 5 downward. The limiting rod 5 presses down on the other inclined surface of the top block 7, causing the top block 7 to rotate in the opposite direction. When the top block 7 rotates in the opposite direction, one inclined surface of it vertically lifts the placement block 4. At the same time, the elastic ejector pin structure on the top of the placement block 4 pops out when the placement block 4 rises, pushing the chip off the placement block 4, achieving rapid demolding.

[0020] As shown in Figures 2 and 3, the machine also includes an electric push rod 8, a discharge block 9, and a collection box 10. At each of the two stations of the bending machine 1, the electric push rod 8 is horizontally and symmetrically arranged with the center of each station as a reference. The telescopic rod of the electric push rod 8 faces horizontally outward from the station. The end of the telescopic rod of the electric push rod 8 is fixedly connected to the discharge block 9. The discharge block 9 is vertically fixed to the telescopic rod and parallel to the station plane, used to contact the side of the chip and smoothly eject the chip. A cuboid collection box 10 is placed at the front of the bending machine 1. The width of the collection box 10 is slightly larger than the total width of the two stations, and the opening of the collection box 10 faces the ejection direction of the discharge block 9. A handle 11 is also included, fixedly connected to the front of the collection box 10. A buffer pad 13 is also included, fixedly connected to the bottom of the collection box 10. Baffles 14 are also included, symmetrically fixedly connected to both sides of the discharge block 9.

[0021] After demolding is completed, the control system triggers the electric push rod 8 to move. The telescopic rods of the electric push rods 8, which are centrally symmetrically arranged horizontally on the two workstations, extend horizontally outwards from the workstations simultaneously. Since the end of the telescopic rod is fixedly connected to the discharge block 9, the discharge block 9 moves with the telescopic rod, contacts the side of the chip, and smoothly pushes the chip outwards from the workstation. The baffles 14 on the left and right sides of the discharge block 9 prevent the chip from slipping to the sides during the push-out process. The pushed-out chip slides smoothly into the collection box 10 located in front of the bending machine 1 through the opening of the collection box 10, which is directly opposite the push-out direction of the discharge block 9, along the pushing direction of the discharge block 9. The buffer pad 13 at the bottom of the collection box 10 is made of rubber, which has good elasticity and shock absorption performance and can prevent damage when the chips are stacked. When the number of chips in the collection box 10 reaches a certain amount, the operator can easily remove the collection box 10 through the handle 11 fixedly connected to the front of the collection box 10 for subsequent processing.

[0022] As shown in Figure 1, the machine also includes a protective plate 12, which is symmetrically fixedly connected to the left and right sides of the bending machine 1 to prevent foreign objects from entering the interior of the bending machine 1.

[0023] During equipment operation, the protective plates 12, which are symmetrically fixedly connected to the left and right sides of the bending machine 1, can prevent foreign objects from entering the interior of the bending machine 1 and protect the normal operation of the equipment.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
