Description

Technical Field

[0001] This utility model relates to the field of chip sorting machine technology, specifically a feeding device for a sorting machine. Background Technology

[0002] During the chip sorting process, the trays carrying the chips need to be accurately and orderly transported into the sorting machine. Currently, a feeding device is commonly used to achieve automatic feeding of the trays. A conventional feeding device usually includes a linear moving platform and an independent clamping mechanism. The clamping mechanism is mostly pneumatic or electric driven, for example, by directly driving the grippers with a cylinder or electric push rod to fix the tray.

[0003] However, the aforementioned prior art has the following significant drawbacks:

[0004] First, adopting a pneumatic or electric clamping solution requires the configuration of corresponding solenoid valves, sensors, air pipes or complex circuit control systems. This not only makes the structure of the entire feeding device complex, occupies a large space and has high manufacturing costs, but also increases the potential risk of equipment failure and makes maintenance more complicated.

[0005] Secondly, to ensure that the clamping mechanism operates at the correct time, additional position detection sensors (such as photoelectric sensors, proximity switches, etc.) are usually required to trigger it. This not only further increases the complexity and cost of the system, but the sensors themselves may also be prone to false triggering or failure, affecting the reliability of the entire feeding process. Utility Model Content

[0006] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a feeding device that ensures stable feeding, has a simple structure, low failure rate, fast response, and low manufacturing and maintenance costs.

[0007] The technical solution adopted by this utility model to achieve the above-mentioned objective is: a feeding device for a sorting machine, including a base, a linear motion module and a clamping mechanism, wherein the linear motion module is provided on the base, and the linear motion module includes a motion table capable of linear motion;

[0008] The clamping mechanism includes a clamping component and a driving component that cooperates with the clamping component. The clamping component is provided on the motion table, and the driving component is provided on the base near the feeding end. When the motion table moves closer to the feeding end of the base, the driving component drives the clamping component to clamp the material tray on the motion table.

[0009] In the above technical solution, the linear motion module adopts the following structure:

[0010] The linear motion module includes a guide rail, a lead screw, and a drive motor. The guide rail is fixedly connected to the base, and the motion table is slidably connected to the guide rail. A lead screw seat is fixedly connected to the motion table, and the lead screw is threadedly connected to the lead screw seat. The drive motor is fixedly connected to the base, and the drive motor is poweredly connected to the lead screw.

[0011] In the above technical solution, the clamping component adopts the following structure:

[0012] The clamping component includes a clamping plate, a spring, a guide platform, and a guide post. The guide platform is fixedly connected to both sides of the moving platform. The guide post is slidably connected to the guide platform. The clamping plate is fixedly connected to the inner end of the guide post. A moving shaft is fixedly connected to each set of clamping plates. The moving shaft passes through the guide platform. The spring is sleeved on the moving shaft. One end of the spring is fixedly connected to the clamping plate, and the other end is fixedly connected to the guide platform.

[0013] Furthermore, when the clamping component adopts the above-described structure, the driving component adopts the following structure:

[0014] The driving component includes two sets of driving plates, which are fixedly connected to both sides of the base. When the motion table moves past the driving plates, the driving plates press down on the motion shaft, causing the two sets of clamping plates to move closer to each other.

[0015] In the above technical solution, in order to ensure that the clamping plate can clamp and position the material tray, the clamping plate includes a flat part and inclined parts located on both sides of the flat part, and the guide platform and guide post are fixedly connected to the flat part.

[0016] In the above technical solution, in order to enable the motion shaft to be smoothly driven by the drive plate, the drive plate includes a guide portion and a pressing portion, and the guide portion is provided with a guide slope.

[0017] In the above technical solution, in order to reduce the wear between the motion shaft and the drive plate, a roller is rotatably connected to the end of the motion shaft.

[0018] The beneficial effects of this utility model are as follows: When loading a chip-containing tray, the tray can be placed on a moving table. Then, a drive motor rotates the lead screw, causing the moving table to move the tray into the sorting machine. When the moving table reaches the inside of the sorting machine, the drive plate presses down on the two sets of moving shafts. At this time, the moving shafts drive the clamping plates to move inward until the two sets of clamping plates clamp the tray. Because the clamping plates have inclined surfaces on both sides, they can better guide the tray into the correct position during clamping, and after clamping, they form a "V-shaped" constraint, effectively preventing the tray from rotating in the horizontal plane. The rotating or translating mechanism achieves precise positioning to ensure the stability of the material tray during sorting. After sorting, the moving table moves the material tray out of the sorting machine. When the moving shaft disengages from the drive plate, the two sets of clamping plates move away from each other under the action of spring force, thus releasing the fixation of the material tray and facilitating subsequent loading and unloading of the material tray. In this way, the clamping mechanism makes full use of the driving force of the linear motion module, so that the feeding device does not have complex electronic or pneumatic components (sensors, solenoid valves, cylinders), but only achieves physical contact when the moving table passes the drive plate. This design has a simple structure, low failure rate, fast response, and low manufacturing and maintenance costs. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figures 1-4 A feeding device for a sorting machine is disclosed. The feeding device mainly includes a base 100, a linear motion module, and a clamping mechanism. The base 100 serves as the basic support structure for the entire device. The linear motion module is mounted on the base 100 and is used to provide precise linear drive. The preferred structure of the linear motion module includes a guide rail 201, a motion table 202, a lead screw 203, and a drive motor 204. The guide rail 201 is fixedly mounted on the base 100 and its direction is consistent with the feeding direction. The motion table 202 is slidably connected to the guide rail 201 and can slide smoothly on the guide rail 201. A lead screw seat is fixedly connected to the motion table 202. The lead screw 203 and the lead screw seat form a threaded pair. The drive motor 204 is fixed on the base 100, and its output shaft is poweredly connected to the lead screw 203 through a coupling. When the drive motor 204 works, it drives the lead screw 203 to rotate, thereby driving the lead screw seat and the motion table 202 fixed thereto to perform precise linear reciprocating motion along the guide rail 201.

[0030] The clamping mechanism is used to clamp and position the tray 500 placed on the motion table 202 at a specific work station. The mechanism includes a clamping component 300 and a driving component 400. The clamping component 300 is directly installed on the motion table 202. Specifically, a guide table 301 is fixedly installed on the upper surface of the motion table 202 near its left and right sides. Each guide table 301 has a guide hole, and a guide post 302 is slidably inserted into the guide hole, so that the guide post 302 can slide horizontally relative to the guide table 301. The inner ends of the two guide posts 302 extend above the bearing area of ​​the motion table 202 and are respectively fixedly connected to a clamping plate 303.

[0031] The clamping plate 303 has a specific external profile. Its main body facing the material tray 500 is a flat part 3031, while the two sides of the flat part 3031 extend to form inclined parts 3032. The inclined parts 3032 can guide the material tray 500 into the correct position during contact and form a "V" constraint after clamping the material tray 500, ensuring that the material tray 500 is stable and the position is accurate.

[0032] In order to drive the clamping plates 303 on both sides to move towards or away from each other, a motion shaft 304 is fixedly connected to each clamping plate 303. The motion shaft 304 passes through the guide table 301 on the corresponding side and extends outward. A spring 305 is sleeved on the section of the motion shaft 304 located between the guide table 301 and the clamping plate 303. One end of the spring 305 is fixed to the clamping plate 303 and the other end is fixed to the guide table 301. In the natural state, the preload of the spring 305 drives the clamping plates 303 on both sides to move away from each other and be in an open state, so as to facilitate the insertion and removal of the tray 500.

[0033] The drive component 400 is fixed on the base 100 and located near the feed end 101 of the base 100. Its function is to automatically trigger the clamping component 300 when the motion table 202 carries the material tray 500 to this position. Specifically, the drive component 400 includes two sets of drive plates 401, which are fixedly installed on both sides of the base 100 and their positions correspond to the movement trajectory of the motion shaft 304 on the motion table 202. The structure of each set of drive plates 401 includes a connected guide part 4011 and a pressing part 4012. The guide part 4011 has a certain guiding slope for initially contacting the motion shaft 304 and guiding it to the correct path. The pressing part 4012 is immediately following the guide part 4011, and its working surface is used to continuously press down on the motion shaft 304 as it continues to move.

[0034] In order to reduce friction, make the movement smoother and improve the service life of parts, a roller 306 is rotatably mounted on the outer end of each motion shaft 304 via a bearing. The contact between the roller 306 and the drive plate 401 is rolling friction.

[0035] The working process of this invention is as follows:

[0036] In the initial state, the motion table 202 is located away from the feed end 101, and the clamping component 300 is in an open state under the action of the spring 305. The operator or the loading robot places the material tray 500 carrying the chip on the motion table 202 between the open clamping plates 303.

[0037] The starting device drives the motor 204 to work, and drives the motion table 202 to move along the guide rail 201 toward the feeding end 101 (i.e., the processing station) through the screw drive. When the motion table 202 approaches the feeding end 101, the rollers 306 at the ends of the motion shafts 304 installed on both sides of the motion table 202 begin to contact the drive plates 401 on both sides of the base 100.

[0038] First, the roller 306 slides along the guide portion 4011 of the drive plate 401, is initially guided and centered. Then, the roller 306 enters the pressing portion 4012. The working surface of the pressing portion 4012 forces the motion shaft 304 to move inward (i.e. towards the center of the motion table 202). The movement of the motion shaft 304 drives the clamping plate 303 fixed thereto to overcome the elastic force of the spring 305 and slide along the guide post 302 towards the center. Finally, the clamping plates 303 on both sides simultaneously clamp the two sides of the material tray 500. The inclined portions 3032 on both sides together form a positioning structure, realizing the precise centering and reliable fixation of the material tray 500.

[0039] In the clamping state, the material tray 500 is precisely positioned at the processing station so that the sorting machine can perform subsequent sorting operations;

[0040] After processing is completed, the drive motor 204 reverses, driving the motion table 202 to carry the material tray 500 away from the feed end 101. As the motion table 202 moves backward, the roller 306 on the motion shaft 304 moves in the opposite direction along the pressing part 4012 and the guide part 4011 of the drive plate 401. The restoring force of the spring 305 begins to be released, pushing the clamping plates 303 on both sides to move apart, thereby releasing the material tray 500 and returning it to the open state, preparing for the next loading or unloading operation.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
