Description

Technical Field

[0001] This utility model relates to the field of metal products technology, specifically to a sorting and unloading device for metal products. Background Technology

[0002] In fields such as machinery manufacturing, automotive parts, and electronic equipment, metal pins are key basic components for connecting, positioning, or transmitting parts. Their dimensional accuracy, surface quality, and mechanical properties directly determine the assembly accuracy and reliability of the final product. For example, if the positioning metal pins of an automotive engine cylinder block have diameter deviations, surface scratches, or internal cracks, it may lead to cylinder block seal failure, causing malfunctions such as oil leakage and reduced engine power. If the metal conductive pins of electronic connectors are deformed or the plating is peeled off, it will cause poor circuit contact and affect the signal transmission stability of electronic equipment. Therefore, the metal pin production process must conduct strict quality inspections to screen qualified products and prevent unqualified products from flowing into the downstream assembly stage.

[0003] Currently, the metal pin detection and sorting process generally suffers from low automation, limited efficiency, high labor costs, and poor detection consistency. In the traditional model, metal pins need to be placed one by one on the detection stage by hand, which is prone to data distortion due to operational errors and restricts the detection cycle. After detection, manual sorting and unloading are still required, but the error rate of manual sorting is high and it is easy to cause customer complaints. In addition, increasing manpower when expanding production will increase costs and exacerbate quality fluctuations due to operational differences. At the same time, manual operation is prone to secondary damage such as scratches and deformation on the surface of metal pins. Utility Model Content

Multiple convex plates are formed at the edges of the rotating table, and bearing stations are mounted on the convex plates. A feeding assembly and an unloading and sorting assembly are integrated on the integrated plate. The bearing station includes an elastic telescopic mechanism located at the bottom of the convex plate. A concave guide block is also fixed at the bottom of the convex plate. One end of the elastic telescopic mechanism forms a U-shaped plate located at the concave surface of the guide block. A waist hole is provided on the U-shaped plate. A receiving tray that can connect with the U-shaped opening and waist hole of the U-shaped plate is embedded in the convex plate. The unloading and sorting assembly includes lifting parts installed on the front and rear sides of the integrated plate. A guide plate and a front push plate are fixed at the ejector ends of the lifting parts, respectively. The front push plate is opposite to the U-shaped plate and is located above the guide plate. An elongated hole is provided on the front push plate, and a diversion part that connects with the elongated hole is provided on the guide plate.

[0005] Furthermore, the elastic telescopic mechanism includes a base block fixed to the bottom of the convex plate and a slider that is slidably connected. An L-shaped limiting block is fixed to one side of the base block, and a stop block located inside the limiting block is fixed to the bottom of the slider.

The front-push plate is fixed to the piston rod of the front-push cylinder, and the piston rod of the side-top cylinder is fixed to a side-top plate. The guide plate is mounted on the side-top plate.

[0007] Furthermore, the diversion section includes a rectangular discharge port on the guide plate, and a channel plate is fixed inside the discharge port. The two discharge ports of the channel plate can be connected to the external guide bag respectively.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] The metal product sorting and unloading device guides metal pins to the bearing station through the feeding component.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7 This embodiment of a metal product sorting and unloading device includes an operating table 1, on which a rotating table 2 is installed, and an integrated plate 4 located around the rotating table 2 is fixed on the operating table 1. Multiple protrusions are uniformly formed on the edge of the rotating table 2, and each protrusion is equipped with a bearing station 3 for bearing metal pins. The integrated plate 4 is integrated with a feeding component 5 for automatic feeding and a unloading and sorting component 6 for sorting and unloading.

[0022] like Figure 3-4The bearing station 3 includes a base block 31 fixed to the bottom of the convex plate and a slider 34 slidably connected to the bottom of the convex plate. An L-shaped limiting block 32 is fixed to the outward edge of the base block 31. A stop block 35 is fixed to the bottom of the slider 34, and the stop block 35 is located inside the limiting block 32. When the slider moves, the stop block can be in contact with the limiting block. The stop block extends downward and its middle part is in contact with the limiting block. The limiting block is used to limit the sliding stroke of the slider 34 by the stop block. Two sets of springs 36 are fixed between the base block 31 and the opposite side of the slider 34. A U-shaped plate 37 is formed at the outward end of the slider 34. The springs 36 can drive the slider 34 and the U-shaped plate 37 to return to their original positions. The bottom of the convex plate is also fixed with A concave guide block 33 is provided, and a U-shaped plate 37 is located at the concave surface of the guide block 33. The guide block guides the U-shaped plate. A waist hole is provided on the U-shaped plate 37. A support plate 38 is embedded in the convex plate. The top of the U-shaped plate 37 is in contact with the bottom of the support plate. When the support plate 38 is in its natural state, the waist hole aligns with the placement area of ​​the support plate 38. The diameter of the waist hole is smaller than the diameter of the metal pin, allowing the metal pin to be supported by the U-shaped plate. At the same time, the waist hole also facilitates the extension of other equipment from the bottom into the support plate during the inspection process. During the unloading process, the U-shaped opening of the U-shaped plate 37 aligns with the placement area of ​​the support plate. The diameter of the U-shaped opening is larger than the diameter of the metal pin, which is used for the positioning and conveying of metal products.

[0023] like Figure 2 and 7The feeding assembly 5 includes a guide block 55 mounted on the integrated plate 4. The guide block has a guide hole adapted to a metal pin and is connected to an external feeding device. The integrated plate 4 also has a side-push cylinder 51 opposite to the side of the guide block 55. The piston rod of the side-push cylinder 51 is fixed to a side-push plate 52, and the side-push plate 52 is slidably connected to the cylinder body of the side-push cylinder 51. An L-shaped plate 53 is fixed to the side-push plate 52. A sealing plate 54 is fixed to one side of the profile plate 53. The sealing plate has a discharge hole that matches the guide hole, and the sealing plate 54 is located below the guide block 55. The side push cylinder 51 can drive the side push plate 52 to move the L-shaped plate 53 and the sealing plate 54, thereby opening and closing the discharge port of the guide block 55. The discharge is completed by controlling the discharge hole and the guide hole on the sealing plate. When the rotating table drives the bearing station to rotate, the empty bearing plate rotates to the discharge port of the guide block. The bottom connection is achieved by moving the sealing plate, which aligns the feeding hole with the guide hole, causing the metal pins in the guide block to fall into the receiving tray. The sealing block is then pushed to close the connection. An external feeding device then feeds the metal pins again until they fall back into the guide block, thus controlling the feeding rhythm. The external feeding device first feeds the metal pins to the feeding port of the guide block, where they remain supported by the sealing plate. Then, when the feeding area of ​​the receiving tray aligns with the feeding port of the guide block, a side-push cylinder drives the sealing plate back, aligning its feeding port with the guide hole and the feeding hole. The metal pins then fall into the receiving tray, completing the feeding. After feeding, the sealing plate seals the feeding port of the guide block again, and the external feeding device feeds the metal pins into the guide block again, completing the feeding cycle. The guide block 55 is a single-material channel, accommodating only one metal pin at a time, and releasing only one metal pin per feeding cycle.

[0024] like Figure 2 , 56. The unloading and sorting assembly 6 includes a front-push cylinder 61 installed on the back of the integrated plate 4 and a side-top cylinder 63 installed on the front of the integrated plate 4. The piston rod of the front-push cylinder 61 is fixedly connected to a front-push plate 62, and the front-push cylinder 61 can drive the front-push plate 62 to move back and forth. The piston rod of the side-top cylinder 63 is fixed to a side-top plate 64. A guide plate 65 is installed on the left side of the side-top plate 64, and the side-top cylinder 63 can drive the guide plate 65 to move horizontally through the side-top plate 64. The head end of the front-push plate 62 is opposite to any stop block, and the front-push plate 62 is located above the guide plate 65. The front-push plate 62 has an elongated hole with a diameter larger than that of the metal pin. The guide plate 65 has a rectangular unloading port, and a dividing plate 66 is fixed inside the unloading port. 6. The rectangular discharge port is divided into two independent discharge channels, and the two discharge channels can be connected to external guide bags respectively to achieve the classified collection of qualified and unqualified products. During the discharge process, the front push cylinder drives the front push plate to push out, thereby pushing the baffle back. At the same time, the slider squeezes the spring, so that the U-mouth of the U-mouth plate is aligned with the discharge area of ​​the receiving tray. Because the diameter of the internal metal pin is smaller than the U-mouth, the metal pin in the receiving tray can fall down and pass through the long hole of the front push plate and through the guide plate to complete the discharge. After the front push plate retracts, the spring force drives the slider to reset until the stop block and the limit block are in contact, so that the waist hole of the U-mouth plate is located below the discharge area of ​​the receiving tray. The action of the side push cylinder 63 is completed before the front push cylinder 61. That is, after the guide plate channel is aligned with the long hole, the front push plate pushes out to push the baffle.

[0025] The integrated plate 4 has an adjusting cylinder 7 mounted on its front side, which is located above the front push plate 62. A sensor 8 is mounted on the bottom of the top end of the adjusting cylinder 7, and the sensor 8 can be positioned opposite to the center of the receiving tray 38. It is used to detect the unloading of metal pins on the receiving tray 38. The adjusting cylinder can drive the sensor to a designated position and detect whether there are metal pins in the receiving tray. If there are, the external controller receives a signal indicating whether the product is qualified or unqualified and starts the side top cylinder to move the guide plate. This aligns the designated unloading channel in the dividing plate with the elongated hole in the front push plate. Then, the front push plate pushes out to complete the unloading operation. After the metal pins fall, the sensor detects that there are no metal pins in the receiving tray, and the rotating table rotates again.

[0026] The working principle of the above embodiments is as follows:

[0027] Before the equipment is started, the rotating table is in a to-be-operated state, and each carrying station on the edge convex plate thereof is in an initial reset state. In the carrying station, the spring is not squeezed by external force, and drives the sliding block and the U-shaped plate to reset. At this time, the waist hole of the U-shaped plate is precisely butted with the placement area of the bearing plate, the diameter of the waist hole is smaller than that of the metal pin, and the waist hole can be used as a temporary support structure for the metal pin. Meanwhile, the blocking plate of the feeding assembly is in a state of blocking the discharging opening of the guide block, an external feeding device has conveyed a single metal pin into the guide hole of the guide block, and the metal pin stays in the guide hole due to the support of the blocking plate. The front push plate and the side top plate of the discharging and sorting assembly are both in a retracted state, and the adjusting cylinder drives the sensor to be in a high-position standby state. After the equipment is started, the rotating table rotates at a constant speed according to a preset rhythm, and drives each carrying station to rotate, sequentially passing through the corresponding station of the feeding assembly, the corresponding station of detection, and the corresponding station of the discharging and sorting assembly, so as to complete the cyclic process of feeding to empty carrying stations, detecting carrying stations with materials, and sorting and discharging metal pins after detection. When the rotating table drives an empty carrying station to rotate to the position right below the feeding assembly, and the placement area of the bearing plate of the carrying station is precisely butted with the discharging opening of the guide block, the feeding stage is started. A side push cylinder receives an instruction from a controller, drives a piston rod to retract, and drives a side push plate fixed therewith to slide along a cylinder body. The side push plate synchronously drives an L-shaped plate and the blocking plate to move horizontally until the discharging hole on the blocking plate is completely aligned with the guide hole of the guide block. At this time, the metal pin in the guide block loses the support of the blocking plate, vertically falls along the guide hole and the discharging hole, and accurately falls into the placement area of the bearing plate of the carrying station below, so that single-time feeding is completed. After the metal pin is discharged, the side push cylinder acts again, drives the side push plate, the L-shaped plate and the blocking plate to move in the reverse direction until the blocking plate blocks the discharging opening of the guide block again. Meanwhile, the external feeding device conveys the next metal pin into the guide hole of the guide block according to a preset rhythm, and waits for the arrival of the next empty carrying station. Thus, the single-time feeding process is ended, and the rotating table continues to drive the carrying station after feeding to move towards the detection station. When the carrying station with the metal pin moves to the position right below the sensor along with the rotating table, the detection preparation stage is started, and the core action centers on the existence detection of the metal pin. The adjusting cylinder receives the instruction, drives the ejection end to move downward, and drives the sensor installed at the bottom to descend to a specified height, so that the sensor is precisely opposite to the center of the bearing plate, ensuring stable detection signals. The sensor detects whether there is a metal pin in the bearing plate. If the metal pin is detected, the sensor transmits a signal to an external controller, the controller combines the detection result (qualified or unqualified) of the previous processing link to send an instruction to the side top cylinder of the discharging and sorting assembly, the side top cylinder drives a piston rod to extend or retract, and drives the side top plate and a guide plate to move horizontally, so that among two independent discharging channels separated by a dividing plate in the guide plate, the channel corresponding to qualified products or unqualified products is pre-aligned with the long hole of the subsequent front push plate, making preparation for subsequent discharging and sorting. When the carrying station after detection preparation moves to the corresponding position of the discharging and sorting assembly along with the rotating table, and the target discharging channel of the guide plate has been aligned with the long hole of the front push plate, the action of the side top cylinder is completed before the front push cylinder,Ensuring the channel is ready in advance, the front-push cylinder receives the command and drives the piston rod to extend, moving the front-push plate forward. The head of the front-push plate contacts the stop block at the bearing station and pushes the stop block to move. The stop block drives the slider fixed to it to slide along the bottom of the convex plate. The slider compresses the spring to deform it, and at the same time, the slider drives the U-shaped plate to move synchronously until the U-shaped opening of the U-shaped plate is precisely aligned with the placement area of ​​the receiving tray. At this time, the diameter of the U-shaped opening is larger than the diameter of the metal pin. The metal pin in the receiving tray falls vertically along the U-shaped opening, passing through the elongated hole of the front-push plate and the target unloading channel of the guide plate in sequence, and finally falls into the external channel connected to the channel. After the metal pins are collected and sorted in the guide bag, and after the metal pins are unloaded, the sensor detects that there are no metal pins in the receiving tray again, and transmits a signal to the controller. The controller instructs the forward-pushing cylinder to retract, causing the forward-pushing plate to reset. After the forward-pushing plate separates from the stop block, the compressed spring releases its elasticity, causing the slider, stop block, and U-shaped plate to move in the opposite direction and reset until the stop block and the limit block are in contact. The waist hole of the U-shaped plate then aligns with the placement area of ​​the receiving tray again, and the bearing station returns to its initial state. At the same time, the rotary table continues to move the reset empty bearing station to the upward feeding assembly, entering the next feeding, detection, and unloading cycle.
