[0002] In modern industrial production, conveyors are widely used in the transportation and transfer of materials. However, in many production processes, it is necessary to accurately position the materials on the conveyor to a specific location for subsequent processing, assembly, detection and other operations. Traditional conveyors often fail to meet the requirements of high-precision positioning, which can lead to inaccurate material positioning, affecting production efficiency and product quality, and are difficult to apply to different sizes of material positioning. Therefore, it is of great practical significance to develop an efficient and accurate conveyor positioning device. SUMMARY

[0003] In view of the deficiencies of the prior art, the utility model provides a positioning device for a conveyor, which solves the technical problem that current conveying equipment cannot position materials of different sizes.

[0005] Preferably, the first power device comprises an adjusting lead screw rotatingly connected to the conveying platform, the adjusting lead screw is threadedly connected between the moving frame, a right-angle motor is arranged on the conveying platform, the adjusting lead screw is driven by the right-angle motor, and the right-angle motor is electrically connected with a controller.

[0006] Preferably, the second power device comprises a driving motor arranged on the moving frame and a bidirectional lead screw rotatingly connected to the inner side wall of the moving frame, the two groups of clamping frames are threadedly connected with the bidirectional lead screw, the bidirectional lead screw is connected with the driving motor, and the driving motor is electrically connected with the controller.

[0007] Preferably, a first guide rod is fixedly connected to the conveying platform, and the first guide rod is slidingly connected with the moving frame.

[0008] Preferably, a second guide rod is fixedly connected to the moving frame, and the two groups of clamping frames are slidingly connected with the second guide rod.

[0009] Preferably, the bottom of the receiving groove is inclinedly provided with a guide plate, and the guide plate is provided with a plurality of rollers.

[0010] Preferably, the inclination angle of the guide plate is between 30° and 45°, and the rollers are made of rubber material.

[0011] Preferably, the moving frame and the clamping frame are made of rust-proof treated steel, and a layer of epoxy resin coating is sprayed on the surface of the steel, and the thickness of the coating is between 0.1mm and 0.3mm.

[0012] Beneficial effects:

[0013] I. By driving the adjusting lead screw to rotate through the right-angle motor in the first power device, the moving frame is accurately displaced on the conveying platform, and the bidirectional lead screw is rotated by the driving motor of the second power device to control the relative motion of the two clamping frames, so that the positioning device can realize high-precision positioning of materials of different sizes and shapes. This precise positioning function can effectively meet the stringent requirements of modern industrial production for the parking of materials at specific positions on the conveyor, thereby greatly improving the accuracy and consistency of subsequent processing, assembly, detection and other processes, reducing the product defect rate caused by material positioning deviation, and improving the overall product quality.

[0014] II. The buffer plates and buffer springs arranged in the receiving grooves of the two clamping frames play a key role. During the process of clamping and placing the material in the receiving groove, whether the material is due to its own motion inertia or external conveying impact, the buffer spring can effectively absorb and disperse these impact forces, avoiding the problem of surface scratching, deformation or even internal structure damage caused by the direct collision of the material with the rigid structure. This is particularly important for the conveying of some precision parts, fragile goods or high-value-added materials, not only ensuring the integrity of the material, but also reducing the economic losses of enterprises due to material damage, while reducing the production downtime and equipment downtime caused by material damage, and improving the production efficiency.

[0015] III. The guide plate and rubber rollers inclinedly arranged at the bottom of the receiving groove cleverly utilize the material gravity and combine the low-friction rolling method, so that the material can be quickly, smoothly and accurately guided to the buffer plate for positioning operation. This material guiding mechanism not only improves the positioning speed of the material and reduces the positioning time of a single material, thereby processing more materials in a unit of time and improving the overall conveying efficiency of the conveyor; moreover, due to its good adaptability, it can be applied to various materials of different shapes, surface characteristics and weights, without the need to frequently adjust the equipment parameters or replace the guiding components for different materials, greatly improving the versatility and flexibility of the equipment, reducing the equipment investment cost and equipment management complexity of enterprises for different material conveying and positioning requirements.

[0032] The driving motor 9 and the bidirectional screw 10 are installed on the moving frame 2, the bidirectional screw 10 is installed on the inner side wall of the moving frame 2 through a bearing, ensuring that it can rotate flexibly, the two sets of clamping frames 3 are threadedly connected with the bidirectional screw 10, and the clamping frame 3 is sleeved on the second guide rod 12, so that the clamping frame 3 can move linearly relative to the bidirectional screw 10 under the guidance of the second guide rod 12, a buffer plate 5 is installed in the receiving groove 4 of the clamping frame 3, the buffer springs 6 are uniformly distributed between the buffer plate 5 and the inner side wall of the receiving groove 4, the pre-compression amount of the buffer springs 6 is adjusted according to the characteristics of the material, so that the buffer springs 6 can provide appropriate buffer force when the material enters the receiving groove 4, a guide plate 13 is installed at the bottom of the receiving groove 4, a roller made of rubber material is installed on the guide plate 13, the inclination angle of the guide plate 13 is adjusted to be between 30° and 45°, and the material can smoothly roll along the guide plate 13 under the action of gravity to the buffer plate 5, finally, the moving frame 2 and the clamping frame 3 are made of rust-proof steel, and a layer of epoxy resin coating with a thickness of 0.1mm to 0.3mm is sprayed on the surface, and the edges are chamfered to improve the durability and safety of the device.

[0033] The right-angle motor 8 and the driving motor 9 are electrically connected with the controller, the power supply circuit and the signal transmission circuit are connected, the circuit connection is firm and there is no problem such as short circuit and open circuit, the controller is programmed and set, the running logic and control parameters of the right-angle motor 8 and the driving motor 9 are set according to the running speed of the conveyor, the size range of the material and other parameters, after the connection is completed, the power-on test is carried out, whether the right-angle motor 8 drives the adjusting screw 7 to move the moving frame 2 smoothly and accurately, whether the driving motor 9 drives the bidirectional screw 10 to move the clamping frame 3 normally, and whether the sensor signals can be accurately transmitted to the controller and correctly responded are checked, the problems are timely investigated and adjusted, such as adjusting the speed of the motor, optimizing the control program, calibrating the sensor, etc., until the whole device can stably and reliably run.

[0034] The material positioning operation process is as follows: when the material is conveyed to the area close to the positioning device on the conveying platform 1, the controller starts the right-angle motor 8 according to the pre-set program or the signal transmitted by the external detection sensor. The right-angle motor 8 drives the adjusting screw 7 to rotate, due to the threaded connection relationship between the adjusting screw 7 and the moving frame 2 and the guiding effect of the first guide rod 11 on the moving frame 2, the moving frame 2 will accurately move horizontally on the conveying platform 1 along the axial direction of the adjusting screw 7, quickly approach the position of the material, so that the two sets of clamping frames 3 can be aligned on both sides of the material.

[0035] Then the controller starts the driving motor 9, the driving motor 9 drives the bidirectional screw 10 to rotate, and since the two sets of clamping frames 3 are in threaded connection with the bidirectional screw 10 and are guided by the second guide rod 12, the two sets of clamping frames 3 will move linearly on the moving frame 2 along the axial direction of the bidirectional screw 10, gradually approaching the material and clamping it stably. The clamped material is placed into the storage groove 4 along with the movement of the clamping frame 3, and when entering the storage groove 4, the material rolls along the inclined guide plate 13, and the rubber roller reduces the frictional resistance between the material and the guide plate 13, so that the material can smoothly roll onto the buffer plate 5. The buffer plate 5 compresses the buffer spring 6 under the impact of the material, the buffer spring 6 absorbs the kinetic energy of the material, converts the impact force into elastic potential energy and slowly releases it, thereby effectively protecting the material from damage and achieving smooth placement and precise positioning of the material in the storage groove 4.

[0036] After the material is positioned, according to the requirements of the subsequent production process, the material can be processed, assembled, detected and other operations at this positioning position, when these operations are completed, the controller reverses the driving motor 9 to release the material from the clamping frame 3, and then controls the right-angle motor 8 to reverse to move the moving frame 2 back to the initial position or to the next material positioning position, preparing for the positioning operation of the next material, and so on, realizing continuous material positioning and conveying work.

[0037] Working principle: The positioning device of the conveyor is mainly based on the principle of mechanical transmission and electrical control to realize the accurate positioning of the material. In terms of mechanical transmission, the first power device utilizes the right-angle motor 8 to drive the adjusting lead screw 7 to rotate, converting the rotary motion of the motor into the linear motion of the moving frame 2, and controlling the moving speed and displacement of the moving frame 2 through the thread lead of the adjusting lead screw 7 and the rotating speed of the right-angle motor 8; the second power device is driven by the driving motor 9 to rotate the bidirectional lead screw 10, converting the rotary motion of the motor into the relative linear motion of the two sets of clamping frames 3, and controlling the clamping force and spacing of the clamping frames 3 through the thread structure of the bidirectional lead screw 10 and the operation of the driving motor 9. In terms of electrical control, the controller serves as the control core of the entire device, receiving signals from various sensors, accurately controlling the start, stop, rotating speed, rotating direction and other parameters of the right-angle motor 8 and the driving motor 9 according to the preset program logic, so as to realize the accurate control of the position of the moving frame 2, the action of the clamping frame 3 and the material positioning process. At the same time, the buffer system composed of the buffer plate 5 and the buffer spring 6 in the receiving groove 4 absorbs the impact energy of the material by utilizing the elastic deformation characteristics of the spring to protect the material; the combination of the guide plate 13 and the roller utilizes the principle of gravity and low friction to guide the material into the buffer plate 5, improving the positioning efficiency and accuracy. The various components of the entire device work cooperatively, ensuring the accurate positioning of the material while taking into account the protection of the material, the stability of the device and the convenience of operation.
