Description

Technical Field

[0001] This utility model relates to the field of conveying and positioning technology for wood processing, and more specifically, to a CNC positioning mechanism for a high-precision conveying system. Background Technology

[0002] Timber requires sawing, which involves cutting long sections of timber into multiple equal-length segments for subsequent processing. During sawing, the timber needs to be fed and transported. Currently, conveyor belts are used for this purpose, but the timber is prone to shifting during transport. This requires manual observation and adjustment, which is inconvenient and prone to significant errors, leading to poor sawing results. Therefore, there is currently a lack of designs that enable high-precision timber feeding and accurate automatic positioning of the timber during the feeding process. Utility Model Content

[0003] The purpose of this invention is to solve the problems mentioned in the background art and to propose a high-precision CNC positioning mechanism for a conveying system.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A high-precision conveying system CNC positioning mechanism includes a conveyor belt, a baffle, a mounting frame, a width detection component, a mounting rod, a horizontal moving assembly, an L-shaped limiting plate, a clamping and positioning assembly, and limiting wheels.

[0006] The baffles are symmetrically fixed on the frame of the conveyor belt;

[0007] The mounting frame is set between two baffles and a width detection device is fixed on the mounting frame above the conveyor belt.

[0008] The mounting rods are symmetrically fixed on the baffle;

[0009] The horizontal movement assembly is positioned between the mounting rod and the baffle.

[0010] The L-shaped limiting plate is connected to the horizontal moving component, and the two L-shaped limiting plates move towards or away from each other synchronously.

[0011] The clamping and positioning components are symmetrically fixed on the baffle;

[0012] Several limit wheels are rotatably connected to two sets of clamping and positioning components and are distributed in a one-to-one correspondence.

[0013] Furthermore, one of the L-shaped limiting plates is fixedly provided with a mounting block, and a distance sensor is fixedly provided on the mounting block at a distance from the other L-shaped limiting plate, with the detection head of the distance sensor facing the gap after the two L-shaped limiting plates have moved towards each other.

[0014] The above solution uses a distance sensor to detect more promptly whether the front end of the wood is in contact with the L-shaped limiting plate (i.e., when the front end of the wood is in contact with the L-shaped limiting plate, the detection value of the distance sensor is within a fixed range, and the distance sensor immediately sends a signal to the controller to stop the conveyor belt). This makes the conveying operation of the device more accurate.

[0015] Furthermore, the clamping and positioning assembly includes a telescopic component and a positioning rod. The telescopic component is symmetrically fixed on the baffle. The telescopic rod of the telescopic component passes through the baffle and is connected to the positioning rod. Several limiting wheels are rotatably connected to the positioning rod.

[0016] Furthermore, the limiting wheel is provided with anti-slip texture.

[0017] In the above solution, after the width detection component detects the current width of the wood, the clamping and positioning component will automatically match the pre-set extension range to ensure that the limiting wheel can accurately contact the side of the wood of different widths to achieve position limitation. The anti-slip texture can prevent the wood from slipping between the wood and the limiting wheel in the future, while the limiting wheel does not affect the normal transmission and transfer of the wood.

[0018] Furthermore, the horizontal movement component employs a lead screw assembly.

[0019] Furthermore, the width detection element is either a measuring light curtain or a laser displacement sensor.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] Compared to existing technologies, this device can automatically limit the front end position of the wood and detect the width of the wood during the conveying process. After the front end is limited and the width is detected, the clamping and positioning components are controlled to accurately position the wood. After positioning, the front end limitation is released and the conveyor belt moves at a constant speed to realize the feeding of the wood. As a result, the conveying accuracy and positioning effect of the wood are significantly improved. There is no need for manual observation and adjustment of the wood position. The wood will not shift position during the sawing and feeding process. Therefore, this device can achieve high-precision conveying and accurate positioning to assist the efficient implementation of subsequent sawing processes and achieve better wood processing results.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0028] like Figure 1 and Figure 2 As shown, a high-precision conveying system CNC positioning mechanism includes a conveyor belt (not shown in the figure), a baffle 1, a mounting frame 2, a width detection component 3, a mounting rod 4, a horizontal movement assembly 5, an L-shaped limit plate 6, a clamping and positioning assembly 7, and limit wheels 8.

[0029] Baffle 1 is symmetrically fixed on the frame of the conveyor belt;

[0030] Mounting frame 2 is installed between two baffles 1 and a width detection component 3 is fixed on the mounting frame 2 above the conveyor belt (specifically, the width detection component 3 adopts either a measuring light curtain or a laser displacement sensor. The measuring light curtain and the laser displacement sensor are both existing technologies and their working principles will not be described).

[0031] Mounting rods 4 are symmetrically fixed on baffle 1;

[0032] The horizontal movement component 5 is disposed between the mounting rod 4 and the baffle 1 (specifically, the horizontal movement component 5 adopts a lead screw assembly);

[0033] The L-shaped limiting plate 6 is connected to the horizontal moving component 5 and the two L-shaped limiting plates 6 move towards or away from each other synchronously.

[0034] The clamping and positioning components 7 are symmetrically fixed on the baffle 1;

[0035] Several limiting wheels 8 are rotatably connected to two sets of clamping and positioning components 7 and are distributed in a one-to-one correspondence.

[0036] Further refinements of the embodiments of this utility model, such as... Figure 1As shown, the clamping and positioning assembly 7 includes a telescopic member 11 and a positioning rod 12. The telescopic member 11 is symmetrically fixed on the baffle 1. The telescopic rod of the telescopic member 11 passes through the baffle 1 and is connected to the positioning rod 12. Several limiting wheels 8 are rotatably connected to the positioning rod 12.

[0037] In a further optimization of the above embodiment, the limiting wheel 8 is provided with anti-slip texture, which is not shown in the figure.

[0038] It should be noted that the conveyor belt, width detection component 3, horizontal movement component 5, and telescopic component 11 are all electrically connected to the controller, which is mounted on one of the mounting rods 4 and is not shown in the figure.

[0039] The working process of this utility model:

[0040] First, place the long timber to be sawed in the middle area of ​​the conveyor belt. Then, the conveyor belt will transport the timber at a constant speed. When the timber passes under the mounting frame 2, the width detection component 3 can automatically detect the width of the timber and feed it back to the controller. It should be noted that the different widths of the timber are all standard sizes. The values ​​of several different widths can be pre-entered into the controller in sequence. There is no need for visual identification. In addition, the corresponding telescopic component 11 motion range is pre-matched for each width of timber to ensure that the limit wheel 8 can accurately contact the side of the timber of different widths to achieve position limitation.

[0041] The initial positions of the two L-shaped limiting plates 6 are as shown in the instruction manual. Figure 1 As shown, at this time, the L-shaped limiting plate 6 can limit the front end position of the wood so that it can not continue to be conveyed forward after reaching and contacting the L-shaped limiting plate 6. After the front end of the wood is limited, the controller controls the conveyor belt to stop. After stopping, the controller controls the telescopic component 11 to move according to the width of the wood according to the preset range, which allows the limiting wheel 8 to contact the two sides of the wood. At this time, the wood can be accurately limited in the middle area of ​​the conveyor belt, so that the position will not be offset during the subsequent sawing and feeding process. The anti-slip texture can prevent the wood from slipping between the limiting wheel 8.

[0042] Once the wood is positioned, the controller controls the horizontal moving component 5 to move, which in turn causes the two L-shaped limiting plates 6 to move out of each other synchronously, thus no longer blocking the front end of the wood. After the obstruction is removed, the controller controls the conveyor belt to resume operation and transmit the wood at a pre-set speed, thereby achieving equidistant feeding during the wood sawing process. Then, the subsequent sawing process can be carried out. The sawing process is prior art and will not be described or shown in this application.

[0043] Compared to existing technologies, this device can automatically limit the front end position of the wood and detect the width of the wood during the conveying process. After the front end is limited and the width is detected, the clamping and positioning component 7 is controlled to accurately position the wood. After positioning, the front end limitation is released and the conveyor belt moves at a constant speed to realize the conveying and feeding of the wood. As a result, the conveying accuracy and positioning effect of the wood are significantly improved. There is no need for a person to observe and manually adjust the position of the wood. The wood will not shift its position during the sawing and feeding process. Therefore, this device can achieve high-precision conveying and accurate positioning to assist the subsequent sawing process to be carried out efficiently, resulting in better wood processing effect.

[0044] In other embodiments, such as Figure 3 As shown, an installation block 9 is fixed on one of the L-shaped limiting plates 6, and a distance sensor 10 is fixed on the installation block 9 at intervals from the other L-shaped limiting plate 6. The detection head of the distance sensor 10 is directly facing the gap after the two L-shaped limiting plates 6 have moved towards each other. In this embodiment, the distance sensor 10 can detect more promptly whether the front end of the wood is in contact with the L-shaped limiting plate 6 (that is, when the front end of the wood is in contact with the L-shaped limiting plate 6, the detection value of the distance sensor 10 is within a fixed range, and then the distance sensor 10 immediately feeds back a signal to the controller to stop the conveyor belt). This makes the conveying operation accuracy of this device better.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
