A positioning and conveying mechanism

Abstract

This utility model discloses a positioning and conveying mechanism, including a frame, a vibratory feeder, a guide assembly, a mounting shell, an infrared detector, an electrostatic eliminator, a moving block, and a driving device. The electrostatic eliminator is mounted on the guide assembly, and its air outlet direction intersects the conveying path of the plastic shell. This allows the airflow generated by the electrostatic eliminator to both remove static electricity and dust from the passing plastic shell, and also to apply a thrust along the conveying path. The moving block is slidably mounted on the frame via the driving device. A limiting groove is formed on the upper surface of the moving block, which is aligned with the outlet of the mounting shell in the initial position to receive the processed plastic shell. The driving device drives the moving block carrying the plastic shell to move. By directly mounting the electrostatic eliminator on the guide assembly and aligning its point of action with the conveying path of the plastic shell, this utility model can simultaneously complete the static electricity removal and dust removal operations on the surface of the plastic shell during the conveying process.

Description

Technical Field

[0001] This utility model particularly relates to a positioning and conveying mechanism. Background Technology

[0002] On automated production and assembly lines for plastic casings (such as electronic device housings and precision instrument packaging boxes), the pre-formed plastic casings need to be transported to subsequent workstations for inspection, assembly, or packaging. Currently, common automated conveying methods include a combination of vibratory feeders and linear guides. The vibratory feeder arranges and orients the randomly stacked plastic casings in an orderly manner, and then transports them to designated positions via guides or channels.

[0003] First, plastic is an excellent insulator, and it easily generates and accumulates static charge after high-speed friction in the vibratory feeder and conveyor channel. The static-charged plastic shell will actively attract fine contaminants such as dust and fibers from the air. For plastic shells used in clean environments (such as the assembly of optical components and medical equipment), this will lead to product contamination and seriously affect the yield of the final product.

[0004] Secondly, to overcome the problem of electrostatic adsorption, some production lines will install static eliminators separately along the conveyor path. However, conventional static eliminators only have the function of neutralizing charges. If the high-speed airflow they generate is not at the right angle, it may interfere with the movement trajectory of plastic shells, especially lighter shells, causing them to get stuck, flip over, or even fall at bends or turning points in the conveyor path, thus disrupting the continuity and stability of the conveyor. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a positioning and conveying mechanism: A positioning and conveying mechanism includes a frame, and a vibratory feeder, a guide assembly, a mounting shell, an infrared detector, an electrostatic eliminator, a moving block, and a driving device mounted on the frame. The inlet end of the guide assembly is connected to the outlet of the vibratory feeder. The mounting shell is fixed below the outlet of the guide assembly, and its interior forms a channel for plastic shells to fall. The infrared detector is disposed on the mounting shell and is used to detect whether a plastic shell passes through. The electrostatic eliminator is disposed on the guide assembly, and its air outlet direction intersects with the conveying path of the plastic shell, so that the airflow generated by the electrostatic eliminator during operation can both remove static electricity and dust from the passing plastic shells and apply a thrust along the conveying path to the plastic shells. The moving block is slidably disposed on the frame by the driving device. A limiting groove is formed on the upper surface of the moving block, which is directly opposite the outlet of the mounting shell in the initial working position to receive the processed plastic shells. The driving device is used to drive the moving block carrying the plastic shells to move.

[0006] Preferably, the frame is provided with a slide rail, and the moving block slides in cooperation with the slide rail; the driving device is a telescopic motor, the output end of which is connected to the moving block to drive it to perform reciprocating linear motion on the slide rail.

[0007] Preferably, the guide assembly includes a bent shell communicating with the vibratory feeder outlet, and a groove is formed inside the bent shell for the plastic shell to slide through; the side wall of the bent shell is provided with an observation gap communicating with the groove, and the radial dimension of the observation gap is smaller than the minimum outline dimension of the plastic shell to prevent the plastic shell from coming out.

[0008] Preferably, a through hole is provided on the bent shell perpendicular to the extension direction of the slide groove; a mounting bracket is fixed to the outside of the bent shell, and a blocking member is provided on the mounting bracket; the blocking member can pass through the mounting bracket and extend into the through hole to selectively block or allow the plastic shell moving in the slide groove.

[0010] Preferably, the static eliminator is an ionizing bar.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention, by directly mounting the static eliminator on the guide assembly and aligning its action point with the conveying path of the plastic shell, enables simultaneous static elimination and dust removal of the plastic shell's surface during transport. This "online" processing not only eliminates the need for subsequent separate cleaning steps, improving efficiency, but more importantly, it eliminates secondary dust contamination caused by electrostatic adsorption at the source, effectively improving product cleanliness and yield. Simultaneously, this integrated design avoids interference with the movement of the plastic shell caused by improper installation of the static eliminator in traditional layouts, ensuring the stability of the conveying process.

The inlet end of the guide assembly is connected to the outlet of the vibratory feeder 2. The mounting shell 3 is fixed below the outlet of the guide assembly, and its interior forms a channel for plastic shells 1-1 to fall. The infrared detector 4 is disposed on the mounting shell 3 to detect whether the plastic shells 1-1 pass through. The electrostatic eliminator 5 is disposed on the guide assembly, and its outlet direction is... Intersecting with the conveying path of the plastic shell 1-1, the airflow generated by the static eliminator 5 during operation can both remove static electricity and dust from the passing plastic shell 1-1, and also apply a thrust to the plastic shell 1-1 along the conveying path direction; the moving block 6 is slidably mounted on the frame 1 by a drive device, and a limiting groove 61 is formed on the upper surface of the moving block 6. The limiting groove 61 is directly opposite the outlet of the mounting shell 3 in the initial working position, and is used to receive the processed plastic shell 1-1. The drive device is used to drive the moving block 6 carrying the plastic shell 1-1 to move.

[0020] Furthermore, the frame 1 is provided with a slide rail 7, and the moving block 6 is slidably engaged with the slide rail 7; the driving device is a telescopic motor, the output end of which is connected to the moving block 6 to drive it to perform reciprocating linear motion on the slide rail 7.

[0021] Furthermore, the guide assembly includes a bent shell 71 that communicates with the outlet of the vibratory feeder 2, and a groove 72 is formed inside the bent shell 71 for the plastic shell 1-1 to slide through; the side wall of the bent shell 71 is provided with an observation gap 73 that communicates with the groove 72, and the radial dimension of the observation gap 73 is smaller than the minimum outline dimension of the plastic shell 1-1 to prevent the plastic shell 1-1 from coming out of it.

[0022] Furthermore, a through hole 710 is provided on the bent shell 71 perpendicular to the extending direction of the slide groove 72; a mounting bracket 8 is fixed on the outside of the bent shell 71, and a blocking member 81 is provided on the mounting bracket 8; the blocking member 81 can pass through the mounting bracket 8 and extend into the through hole 710 to selectively block or allow the plastic shell 1-1 moving in the slide groove 72.

[0023] Furthermore, the static eliminator 5 is fixedly installed on the outside of the bent section of the bent shell 71; the air supply end of the static eliminator 5 passes through the observation gap 73 and extends into the slide groove 72, and its air supply direction is aligned with the conveying path of the plastic shell 1-1.

[0024] Furthermore, the static eliminator 5 is an ion bar.

[0025] The working principle of this utility model is as follows: A plastic shell 1-1 is placed inside a vibratory feeder 2. Under the vibration of the vibratory feeder 2, the plastic shell 1-1 inside the vibratory feeder 2 will pass through a guide assembly and enter a mounting shell 3. The mounting shell 3 can be fixed with bolts directly below the outlet of the guide assembly, forming a vertical material drop channel. In this application, an infrared detector 4 is provided on the mounting shell 3. As an embodiment 1, the infrared detection in this application is preferably a through-beam sensor, with its transmitting end and receiving end respectively installed on both sides of the mounting shell 3. When the plastic shell 1-1 falls and blocks the infrared beam, the sensor sends a "pass" signal. If the vibratory feeder 2 or the guide channel is blocked, causing the plastic shell 1-1 to fail to arrive at the predetermined time and block the beam, the sensor will not be able to generate a "pass" signal. Therefore, the infrared detector 4 is a key component for detecting whether the plastic shell 1-1 is moving normally.

[0026] This application also includes an antistatic device 5 on the guide assembly. In this embodiment, the guide assembly includes a bent shell 71 that communicates with the outlet of the vibrating plate 2. A groove 72 is formed inside the bent shell 71 for the plastic shell 1-1 to slide through. Preferably, the antistatic device 5 is provided at the bend of the bent shell 71. The antistatic device 5 can be implemented by using an ion bar. That is, the ion wind blown by the ion bar can not only neutralize the static electricity on the surface of the plastic shell 1-1 and blow off the attached dust, but also push the plastic shell 1-1 smoothly through the bend when it is in the bend, so as to prevent the plastic shell 1-1 from being blocked in the bend.

[0027] Based on the above technical solution, the cleaned plastic shell 1-1 falls into the limiting groove 61 of the moving block 6 located directly below under the action of its weight. Then, the driving device drives the moving block 6 to move along the slide rail 7, transporting the positioned plastic shell 1-1 from its "receiving station" to the next process, thereby completing a work cycle.

[0028] Based on the above technical solution, this application provides a sliding groove 72 inside the bent shell 71 for the plastic shell 1-1 to slide, which is used to guide the movement of the plastic shell 1-1; in order to facilitate monitoring of the movement of the plastic shell 1-1 in the sliding groove 72, this application provides an observation gap 73 on the side wall of the bent shell 71. The width of the observation gap 73 is much smaller than the minimum outline size of the plastic shell 1-1, so as to provide a good field of vision while absolutely preventing the plastic shell 1-1 from accidentally falling out when stuck or moving at high speed.

[0029] Based on the above technical solution, this application further adds a manual blocking mechanism to the bending shell 71. This manual blocking mechanism includes a through hole 710 penetrating the bending shell 71, a mounting bracket 8 welded to the outside of the bending shell 71, and a blocking component 81 screwed onto the mounting bracket 8. When it is necessary to pause the feeding, the operator can manually screw the blocking component 81, causing the middle section of the blocking component 81 to extend into the chute 72, gently blocking the subsequent plastic shells 1-1, thus achieving rapid start-up and stop control of the production line.

[0030] In a preferred embodiment of this application, the static eliminator 5 is innovatively arranged at a key location in the guide assembly. Specifically, the static eliminator 5 is fixed to the mounting bracket 8, and the air outlet of the static eliminator 5 extends into the observation gap 73, facing the plastic shell 1-1 passing through the bending section. This arrangement allows the ionizing air generated by the static eliminator 5 to not only efficiently neutralize the static electricity on the surface of the plastic shell 1-1 and remove dust, but also to apply a continuous auxiliary thrust to the plastic shell 1-1 using the power generated by the airflow. This thrust effectively overcomes the problem of the plastic shell 1-1 getting stuck or not flowing smoothly in the bending section due to friction or insufficient gravity, ensuring a smooth and stable conveying process.

[0031] This invention, by directly mounting the static eliminator 5 onto the guide assembly and aligning its action point with the conveying path of the plastic shell 1-1, enables simultaneous static elimination and dust removal of the plastic shell 1-1's surface during its conveying process. This "online" processing not only eliminates the need for subsequent separate cleaning steps, improving efficiency, but more importantly, it eliminates secondary dust contamination caused by electrostatic adsorption at the source, effectively improving product cleanliness and yield. Simultaneously, this integrated design avoids interference with the movement of the plastic shell 1-1 caused by improper installation of the static eliminator 5 in traditional layouts, ensuring the stability of the conveying process.

Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
