Description

Technical Field

[0001] This utility model relates to the field of product screening technology, and in particular to a high-precision, high-speed front and back screening mechanism. Background Technology

[0002] In the field of industrial automation production, the screening of materials by their front and back sides is a crucial step in ensuring the accuracy of subsequent assembly and processing. This is especially true for micro-parts, precision components, or irregularly shaped materials, where accurate differentiation of their front and back states directly impacts product yield and production efficiency. Current technologies generally employ vibratory feeder screening mechanisms. These mechanisms use high-frequency vibration to move materials along a spiral track, relying on mechanical structures such as bosses and notches on the track for directional screening. However, these mechanisms have certain shortcomings: high-frequency vibration can easily cause surface scratches, structural deformation, or hidden damage to materials, particularly affecting fragile precision parts; they have poor adaptability to irregularly shaped parts, sticky materials, or lightweight materials, resulting in low screening efficiency; and they can only perform coarse screening based on size and shape, failing to integrate multi-dimensional detection, thus requiring further improvement in detection accuracy. 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, high-speed front and back screening mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-precision, high-speed front and back screening mechanism, comprising:

[0006] It includes a product transport assembly and a product gripping and rotating mechanism, wherein the product gripping and rotating mechanism is connected to the product transport assembly;

[0007] The product transport assembly includes a speed-regulating motor, a conveyor belt, a stop cylinder, a blocking block, a product arrival detection sensor, and a detection laser sensor group; the conveyor belt is driven by the speed-regulating motor, the blocking block is connected to the drive end of the stop cylinder, and the product arrival detection sensor and the detection laser sensor group are both installed on the side of the conveyor belt.

[0008] The product gripping and rotating mechanism includes a gripper cylinder, a gear, a rack, a rack push-pull cylinder, and a vertical lifting cylinder; the gripper cylinder is connected to the drive end of the vertical lifting cylinder, the gear is connected to the gripper cylinder, the rack meshes with the gear, and the rack is connected to the drive end of the rack push-pull cylinder.

[0009] Preferably, the detection laser sensor group includes a first detection laser sensor and a second detection laser sensor, both of which are fixedly connected to the side wall of the conveyor belt.

[0010] Preferably, the conveyor belt is a polyurethane belt.

[0011] Compared with the prior art, this utility model provides a high-precision, high-speed front and back screening mechanism, which has the following advantages:

[0012] 1. This utility model uses a detection laser sensor group consisting of a first detection laser sensor and a second detection laser sensor to perform dual detection of the front and back sides of the material. Combined with real-time data analysis by a PLC control module, it effectively improves the accuracy of front and back side judgment, avoids misjudgment that may be caused by a single sensor, and ensures screening accuracy.

[0013] 2. This utility model uses a speed-regulating motor to drive the conveyor belt for material conveying. Compared with the high-frequency vibration conveying method of the traditional vibratory plate, the conveying speed is more stable and can be flexibly adjusted, which can adapt to the high-speed cycle requirements of modern production lines. At the same time, the product clamping and rotating mechanism achieves 180° rapid rotation through the cooperation of gears and racks, which can realize continuous screening operations and effectively improve the overall production efficiency.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1:

[0020] Reference Figures 1-3A high-precision, high-speed front and back screening mechanism, comprising:

[0021] It includes a product transport assembly 100 and a product gripping and rotating mechanism 200, the product gripping and rotating mechanism 200 being connected to the product transport assembly 100;

[0022] The product transport assembly 100 includes a speed-regulating motor 101, a conveyor belt 102, a stop cylinder 103, a blocking block 104, a product arrival detection sensor 105, and a detection laser sensor group. The conveyor belt 102 is connected to the speed-regulating motor 101, the blocking block 104 is connected to the drive end of the stop cylinder 103, and the product arrival detection sensor 105 and the detection laser sensor group are both installed on the side of the conveyor belt 102.

[0023] The product gripping and rotating mechanism 200 includes a gripper cylinder 201, a gear 202, a rack 203, a rack push-pull cylinder 204, and a vertical lifting cylinder 205. The gripper cylinder 201 is connected to the drive end of the vertical lifting cylinder 205, the gear 202 is connected to the gripper cylinder 201, the rack 203 meshes with the gear 202, and the rack 203 is connected to the drive end of the rack push-pull cylinder 204.

[0024] The detection laser sensor group includes a first detection laser sensor 106 and a second detection laser sensor 107, both of which are fixedly connected to the side wall of the conveyor belt 102.

[0025] Reference Figures 1-3 In practical use, the product to be screened is placed at the entrance of the product transport component 100. At this time, the stop cylinder 103 is in the extended state, and the blocking block 104 connected to its drive end cooperates to stop and limit the product, preventing the product from being directly transported without processing. The speed-regulating motor 101 is powered on and started, and the conveyor belt 102 connected to the speed-regulating motor 101 starts to rotate, transporting the product at the entrance to the screening functional area.

[0026] During the inspection, when the product is conveyed to the blocking block 104, the product arrival detection sensor 105 installed next to the conveyor belt 102 detects the product arrival signal. This signal is transmitted to the external controller. After the product arrives, the first detection laser sensor 106 and the second detection laser sensor 107, which are also installed next to the conveyor belt 102, start to detect the front and back of the product, acquire the front and back status data of the product in real time and transmit it to the external controller.

[0027] The external controller determines the current status of the product based on the received signals;

[0028] When the product is in the forward position, the stop cylinder 103 retracts after receiving the signal, and the conveyor belt 102 transports the product to the next process.

[0029] When the product is in the reverse position, the product gripping and rotating mechanism 200 receives an instruction, and the vertical lifting cylinder 205 drives the gripper cylinder 201 to descend, and the gripper cylinder 201 clamps the product; then the vertical lifting cylinder 205 rises, and the rack push-pull cylinder 204 drives the rack 203 connected to its driving end to move in a straight line. Since the rack 203 meshes with the gear 202, the gear 202 drives the gripper cylinder 201 connected to it to rotate 180°, so that the product is flipped to the front.

[0030] After the product is flipped over, the detection laser sensor group detects the product again. Once it is confirmed that the product is in the front position, the vertical lifting cylinder 205 descends, the gripper cylinder 201 releases the product, the stop cylinder 103 retracts, and the conveyor belt 102 transports the product to the next process.

[0031] It should be noted that the external controller can be a PLC control module, specifically a Siemens S7-1214C controller.

[0032] Reference Figure 1 , Figure 2 In practice, the conveyor belt 102 is a polyurethane belt.

[0033] By setting the conveyor belt 102 as a polyurethane belt, the product can be effectively protected, the damage to the product during the conveying process can be reduced, the conveying safety can be improved, and the product yield can be increased.

[0034] It should be noted that the control circuit in this device can be implemented by a person skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
