Description

Technical Field

[0001] This application relates to the field of workpiece processing and production technology, and in particular to a product pin forming processing production line. Background Technology

[0002] Electronic components, especially electronic connectors, are generally equipped with metal pins. The pins are mounted on an insulating base, and the assembly methods are generally through insertion or injection molding. Insertion refers to inserting the pins into pre-set holes in the insulating base, while injection molding refers to placing the pins into a mold and directly injection molding to create an insulating base that is seamlessly fixed to the pins.

[0003] In related technologies, after the insulating base with pins is produced by injection molding, pin cutting equipment is needed to cut the pins. For some electronic components with special functional requirements, additional pins need to be inserted into the pre-set holes in the insulating base after cutting. Existing pin mounting equipment has limited functionality. When a product needs to use both through-hole and injection molding production methods, manual intervention is required during the processing. For example, manually placing the pins in each base, manually positioning excess pins for machine cutting, or manually positioning and flipping the product are all necessary. This method has low production efficiency and consumes a lot of human resources. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a product pin forming production line, which can improve the production efficiency of products containing pins, reduce the consumption of human resources, and increase the product yield.

[0006] A bending and shearing device includes a material roll feeding module, a bending module, a shearing module, and a first material transfer module.

The bending module is located on the first transmission path and behind the material roll feeding module, and is used to bend the pin assembly on the material strip. The shearing module is located on the first transmission path and behind the bending module, and is used to cut off the bent pin assembly on the material strip.

[0007] The injection molding equipment includes a second transfer module and an injection molding machine; the first transfer module is used to transfer the pin assembly to the second transfer module, so that the second transfer module transports the pin assembly into the injection molding machine for processing and forms a semi-finished product containing a base;

The third material transfer module is disposed on a second transmission path and is used to transport semi-finished products to the cutting module. The cutting module is disposed on the second transmission path and located behind the third material transfer module, and is used to cut the pin components on the semi-finished product to form a plurality of first pins. The secondary inserting module is disposed on the second transmission path and located behind the cutting module, and is used to install second pins on the semi-finished product to form a finished product.

[0009] A testing and traying device includes a fourth material transfer module, a testing module, and a traying module.

[0010] The product pin forming processing production line according to the first aspect of this application has at least the following beneficial effects: In the process of producing products containing pins, the material is first fed through the material roll feeding module in the bending and shearing equipment. The material strip includes pin assemblies arranged at intervals. Each pin assembly includes several first pins connected at one end. The material strip moves towards the bending module along the first transmission path. The bending module bends the first pins in the pin assembly by 90 degrees, so that the first pins in the finished product are vertically exposed on the outside of the base. The material strip continues to move towards the shearing module along the first transmission path. The shearing module cuts the material strip into small segments, each segment including a pin assembly. Finally, each pin assembly is transferred to the second transfer module by the first transfer module. The second transfer module transports the pin assembly to the injection molding machine for processing, where it is injection molded with the base to form a semi-finished product. The third transfer module in the cutting and insertion equipment transports the semi-finished product to the cutting module, which cuts open the ends of the pin assembly, transforming it into several separate first pins, completing the pin injection molding process. The semi-finished product then continues to move along the second transfer mechanism to the secondary insertion module, where second pins are installed, completing the pin insertion process and forming the finished product. The fourth transfer module moves the finished product along the third transfer path to the inspection module, where each finished product undergoes dimensional inspection. The tray-setting equipment then sorts and arranges the finished products according to the inspection results. The pin molding and processing production line provided in this application automates the pin injection molding and insertion process, ensuring a high yield rate for each finished product through dimensional inspection. This improves the production efficiency of products containing pins, reduces manpower consumption, and increases the product yield rate.

The rear side of the 00 is used to bend the pin assembly on the material strip; the shearing module 1300 is set on the first transmission path and located behind the bending module 1200, and is used to cut off the bent pin assembly on the material strip; the injection molding equipment 200 includes a second transfer module 2100 and an injection molding machine 2200; the first transfer module 1400 is used to transfer the pin assembly to the second transfer module 2100, so that the second transfer module 2100 transports the pin assembly into the injection molding machine 2200 for processing and forms a semi-finished product containing a base; The cutting and inserting equipment 300 includes a third transfer module 3100, a cutting module 3200, and a secondary inserting module 3300. The third transfer module 3100 is disposed on the second transmission path and is used to transport the semi-finished product to the cutting module 3200. The cutting module 3200 is disposed on the second transmission path and located behind the third transfer module 3100, and is used to cut the pin components on the semi-finished product so that the pin components form a plurality of first pins.

[0060] In the production of products containing pins, the material is first fed into the roll feeding module 1100 of the bending and shearing equipment 100. The roll contains spaced-apart pin assemblies, each pin assembly including several first pins connected at one end. The roll moves along the first transmission path to the bending module 1200, where the first pins in the pin assemblies are bent at a 90-degree angle, so that the first pins in the finished product are vertically exposed on the outside of the base. The roll continues to move along the first transmission path to the shearing module 1300, where the shearing module 1300 cuts the roll into small segments, each segment including a pin assembly. Finally, the first transfer module 1400 transfers each pin assembly to the second transfer module 2100, which then transports the pin assembly to the injection molding machine 22. Within 00, processing is carried out to form a semi-finished product by injection molding with the base. The third transfer module 3100 in the cutting and insertion equipment 300 transports the semi-finished product to the cutting module 3200. The cutting module 3200 cuts open the end of the pin assembly, so that the pin assembly is transformed into several separate first pins, completing the pin injection molding process of the product.

[0061] Reference Figure 2The bending and shearing equipment 100 provided in this application also includes a guide module 1500. The guide module 1500 is disposed on the first transmission path and located between the material roll unloading module 1100 and the bending module 1200. The guide module 1500 includes a support rod 1510, a guide assembly 1520 and several sensing positions 1530. The guide assembly 1520 is vertically and vertically disposed on the support rod 1510. The guide assembly 1520 is provided with a material strip roller 1540 and a sensing plate 1550. The material strip roller 1540 is aligned with the unloading point of the material roll unloading module 1100. The sensing plate 1550 is located on one side of the support rod 1510. Several sensing positions 1530 are disposed on one side of the support rod 1510. The sensing positions 1530 are used to sense the sensing plate 1550. The guide assembly 1520 has two sensing positions 1530. One sensing position 1530 is located on the upper part of the support rod 1510, and the other sensing position 1530 is located on the lower part of the support rod 1510, corresponding to the upper limit and lower limit, respectively. The material strip passes through the material strip rollers 1540. Under the action of the material strip, the guide assembly 1520 slides up and down along the vertically arranged support rod 1510 through a sliding structure. When the guide assembly 1520 slides up to the upper limit, the sensing plate 1550 is sensed by the sensing position 1530 located on the upper part of the support rod 1510. At this time, the material roll unloading module 1100's output speed is too slow, so the unloading speed is increased. When the guide assembly 1520 slides down to the lower limit, the sensing plate 1550 is sensed by the sensing position 1530 located on the lower part of the support rod 1510. At this time, the material roll unloading module 1100's output speed is too fast, so the unloading speed is slowed down.

[0062] Reference Figures 3 to 5It is understood that the bending and shearing equipment 100 also includes two feeding roller modules 1610, two discharging pinwheel modules 1620, and a buffer module 1630; the two feeding roller modules 1610 are both arranged on the first transmission path and are located in front of the bending module 1200 and the shearing module 1300, respectively; the feeding roller module 1610 includes a pair of rollers 1611 and a pair of limiting plates 1612. The first transmission path passes through the gap between the two first rollers of the pair of rollers 1611, and the pair of limiting plates 1612 is arranged on one side of the pair of rollers 1611. The two limiting plates of the pair of limiting plates 1612 are connected along the first transmission path. The path forms a material strip groove; two discharge pinwheel modules 1620 are both disposed on the first transmission path and are located behind the bending module 1200 and the shearing module 1300, respectively; the discharge pinwheel module 1620 includes a take-up pinwheel 1621, a pressure roller 1622, a material strip detection device 1623, and a first driving member 1624. The first driving member 1624 is used to drive the take-up pinwheel 1621 to rotate. The pressure roller 1622 is movably disposed above the take-up pinwheel 1621 through a slide rail slider structure. The material strip detection device 1623 is disposed on one side of the take-up pinwheel 1621 and is used to sense the position of the material strip. In one embodiment, the material strip detection device 1623 of the discharge pinwheel module 1620 is a through-beam optical fiber. The through-beam optical fiber is disposed on one side of the feed strip of the discharge pinwheel module 1620. During operation, the material strip passes between the through-beam optical fibers, and the position of the material strip is sensed by the through-beam optical fibers. During operation, the strip enters from one side of the bending module 1200 and exits from the other side, entering the discharge pinwheel module 1620. After entering the discharge pinwheel module 1620, the strip first passes between the optical fibers, then between the take-up pinwheel 1621 and the pressure roller 1622. Driven by the take-up pinwheel 1621, the strip moves towards the shearing module 1300. Under the action of the slide rail slider structure, the pressure roller 1622 applies flexible pressure to the strip. Pressure is applied to press the material strip onto the take-up needle wheel 1621, while avoiding excessive pressure that could damage the material strip. The through-beam optical fiber senses the material strip and notifies the bending module 1200 to operate. The bending module 1200 bends the product on the material strip that has reached the bending position. The working principle of the discharge needle wheel module 1620, located behind the shearing module 1300, is similar to that of the discharge needle wheel module 1620 behind the bending module 1200, and will not be described in detail here.

[0063] The buffer module 1630 is disposed on the first transmission path and located between the adjacent feed roller module 1610 and discharge pinwheel module 1620; one of the discharge pinwheel modules 1620 is disposed on one side of the discharge belt of the bending module 1200.

The buffer module 1630 is disposed on the first transmission path and located between the adjacent feed roller module 1610 and discharge pinwheel module 1620. The material belt passes through the discharge pinwheel module 1620 on the discharge belt side of the bending module 1200, then passes over and rests on the second roller 1631 of the buffer module 1630, and then passes through the feed roller module 1610 on the feed belt side of the shearing module 1300 before entering the shearing module 1300. During operation, if the material belt becomes taut due to inconsistent speeds between the front and rear sections, the second roller 1631 is driven downward by the material belt to form a buffer, preventing the material belt from becoming too taut. After buffering, the second roller 1631 is reset under the action of the first elastic element 1635. Alternatively, if the material belt becomes too long between the feed roller module 1610 and the discharge pinwheel module 1620, causing it to become loose, the second roller 1631 moves upward under the action of the first elastic element 1635 to ensure the material belt is taut and avoid the problem of easy displacement caused by excessive looseness. The buffer module 1630 is designed to prevent the material belt from becoming too tight, which could lead to breakage or deformation, and also to prevent it from becoming too loose, which could cause easy displacement.
