Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to a part size detection device. Background Art

[0002] In modern manufacturing, the dimensional accuracy of parts directly impacts product assembly quality and overall performance. Therefore, dimensional inspection is an essential step in the production process. Traditional methods for inspecting part dimensions rely heavily on manual labor, with workers using hand-held measuring tools to inspect parts. While manual measurement can guarantee accuracy to a certain extent, its efficiency is low, making it particularly inefficient in large-scale production and unable to meet the demands of industrial automation.

[0003] After searching, it was found that Chinese patent literature discloses a dimension detection device for mechanical parts processing [Application No.: 202321003358.0, Publication No.: CN219956420U], which includes a base, a detection platform is installed in the middle of the top of the base, and a groove is opened at the top of the detection platform. A top plate is provided on the inner side of the groove, and a ejection structure is connected to the bottom of the top plate. Although this device can detect the size of parts, it cannot detect in batches and can only detect the dimensions in two directions at the same time, which no longer meets the requirements. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a part size detection device.

[0005] A part size detection device includes a detection platform, characterized in that the detection platform includes a conveying device group, a detection device group and a base plate, and the conveying device group and the detection device group are both installed on the base plate.

[0006] The conveying equipment group includes a conveyor line main frame, a conveyor belt, a variable speed motor, a transmission wheel group and several pairs of baffles. The transmission wheel group is arranged at the bottom of the conveyor line main frame, and the conveyor belt is wrapped around the whole formed by the conveyor line main frame and the transmission wheel group. The output end of the variable speed motor is connected to the input end of the transmission wheel group. The variable speed motor drives the transmission wheel group to rotate, thereby driving the conveyor belt to rotate. The baffles are evenly and equidistantly arranged on the top of the conveyor line main frame and the conveyor belt.

[0007] The detection equipment group includes side inspection equipment 1, side inspection equipment 2, top inspection equipment, pusher 1, pusher 2 and pusher 3. Side inspection equipment 1 is provided on one side of the conveyor line main frame, and side inspection equipment 2, top inspection equipment, pusher 1, pusher 2 and pusher 3 are provided on the other side of the conveyor line main frame. The distances of side inspection equipment 1, side inspection equipment 2, top inspection equipment, pusher 1, pusher 2 and pusher 3 from the speed motor are from far to near as shown in the figure: side inspection equipment 1, pusher 1, side inspection equipment 2, pusher 2, top inspection equipment and pusher 3.

[0008] Preferably, the pushing blocks of pusher 1, pusher 2 and pusher 3 are respectively arranged in the gaps between the baffle plates on the same side.

[0009] With this technical solution, when the inspection equipment detects that a part's dimensions don't meet the set standards, the control system issues a command to activate the corresponding pusher. The pusher precisely extends through the gaps between the retaining plates, pushing the rejected part off the conveyor belt into the receiving chute, preventing it from continuing to the next processing step.

[0010] Preferably, conveying rollers are provided at both ends of the conveying line main frame.

[0011] Through the above technical solution, the tensioning and transmission of the conveyor belt are more stable, ensuring that the parts can maintain a stable running state during the transmission process, and will not cause part position deviation or detection error due to loosening or slipping of the conveyor belt.

[0012] Preferably, the baffle plate is L-shaped.

[0013] Through this technical solution, the L-shaped baffle design fully utilizes its structural advantages. Its vertical portion effectively blocks lateral movement of parts, while the horizontal portion provides additional support, ensuring that the parts are always at the correct inspection angle. Especially when dealing with irregularly shaped or smooth parts, the L-shaped baffle's surrounding effect significantly improves stability during the conveying process, reduces part displacement caused by vibration or external forces, and thus improves the accuracy of the inspection equipment.

[0014] Preferably, fill lights are provided on the opposite sides of the side inspection device 1, the side inspection device 2, and the top inspection device, and the fill lights are all installed on the main frame of the conveyor line.

[0015] Through the above technical solution, the fill lights are all installed on the main frame of the conveyor line. Through the above technical solution, the fill lights can provide stable and sufficient lighting conditions for the inspection area, ensuring that the surface of the part is evenly illuminated during the inspection process, thereby improving the accuracy and reliability of image inspection.

[0016] Preferably, the opposite sides of pusher 1, pusher 2 and pusher 3 are all equipped with material receiving troughs, and the material receiving troughs are all installed on the main frame of the conveyor line.

[0017] Through the above technical solution, the receiving trough can effectively receive the unqualified parts pushed out by the pusher, preventing them from falling or mixing with the qualified parts on the conveyor belt, thereby realizing the automatic sorting and collection of unqualified products.

[0018] Preferably, the side visual inspection device 1, the side visual inspection device 2, the pusher 1, the pusher 2 and the pusher 3 are all equipped with detectors, the detectors are installed on the baffle plate, and the detectors are all located on the same side.

[0019] Through the above technical solution, the detector can detect in real time whether the material has arrived at the designated location and send a signal to the control system to ensure the smooth progress of the detection and sorting process.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] 1. This part dimensional inspection equipment is equipped with a three-dimensional visual inspection system, enabling comprehensive dimensional inspection from different angles of the part. Compared to traditional single-directional inspection, three-dimensional inspection not only captures information about the side and top of the part, but also ensures that even complex shapes and dimensional deviations are accurately detected. This multi-angle inspection method significantly improves the equipment's detection accuracy and reduces the possibility of omissions or misjudgments.

[0022] 2. This part size inspection equipment, through a combination of a conveyor belt and an automatic pusher, enables continuous inspection of large quantities of parts. The pusher allows unqualified parts to be quickly and accurately sorted from the conveyor belt without affecting the flow of qualified parts. This automated batch inspection method significantly improves production efficiency and is suitable for the efficient operation of large-scale production lines. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 2 The present invention provides a technical solution: a part size detection device, characterized in that:

[0028] A part size detection device includes a detection platform, characterized in that the detection platform includes a conveying device group, a detection device group and a base plate 1, and the conveying device group and the detection device group are both installed on the base plate 1.

[0029] The conveying equipment group includes a conveyor line main frame 101, a conveyor belt 102, a variable speed motor 103, a transmission wheel group 104 and several pairs of material baffles 105. The transmission wheel group 104 is arranged at the bottom of the conveyor line main frame 101, and the conveyor belt 102 is wrapped around the whole formed by the conveyor line main frame 101 and the transmission wheel group 104. The output end of the variable speed motor 103 is connected to the input end of the transmission wheel group 104. The variable speed motor 103 drives the transmission wheel group 104 to rotate, thereby driving the conveyor belt 102 to rotate. The material baffles 105 are evenly and equidistantly arranged on the top of the conveyor line main frame 101 and the conveyor belt 102.

[0030] The inspection equipment group includes side inspection equipment 1 201, side inspection equipment 2 202, top inspection equipment 203, pusher 1 204, pusher 2 205 and pusher 3 206. Side inspection equipment 1 201 is provided on one side of the conveyor line main frame 101, and side inspection equipment 2 202, top inspection equipment 203, pusher 1 204, pusher 2 205 and pusher 3 206 are provided on the other side of the conveyor line main frame 101. The distances of side inspection equipment 1 201, side inspection equipment 2 202, top inspection equipment 203, pusher 1 204, pusher 2 205 and pusher 3 206 from the speed motor 103 are, from far to near, side inspection equipment 1 201, pusher 1 204, side inspection equipment 2 202, pusher 2 205, top inspection equipment 203 and pusher 3 206.

[0031] Specifically, the pushing blocks of pusher 1 204, pusher 2 205 and pusher 3 206 are respectively arranged in the gaps between the baffle plates 105 on the same side. Through the segmented setting of multiple pushers, the equipment can realize multi-level screening function, and classify and process defects found in different detection stages, so that the production line has higher flexibility and accuracy.

[0032] Specifically, conveyor rollers 106 are installed at both ends of the conveyor line main frame 101. The placement of these rollers facilitates the circulation of the conveyor belt 102. The interaction of the front and rear conveyor rollers 106 ensures that the conveyor belt 102 is evenly stressed throughout the entire conveyor line main frame 101, preventing wear or abnormal tension on the conveyor belt 102 caused by uneven stress at a single point. Furthermore, the conveyor rollers 106 can flexibly adjust the tension of the conveyor belt 102 to accommodate varying test loads, further enhancing the stability of the equipment.

[0033] Specifically, the baffle plate 105 is L-shaped. The design of the L-shaped baffle plate 105 fully utilizes its structural advantages. Its vertical part can effectively block the lateral movement of the parts, while the horizontal part provides additional support to ensure that the parts are always at the correct detection angle. The L-shaped baffle plate 105 can optimize the relative position between the parts and the detection equipment to ensure that each part can be accurately detected. This structure not only improves the detection accuracy, but also simplifies the guidance and positioning system of the parts, reducing the complexity and failure rate of the equipment.

[0034] Specifically, fill lights 207 are provided on the opposite sides of the side inspection device 1 201, the side inspection device 2 202, and the top inspection device 203. The fill lights 207 are all installed on the conveyor line main frame 101. The fill lights 207 can provide stable and sufficient lighting conditions for the inspection area, ensuring that the surface of the parts is evenly illuminated during the inspection process, thereby improving the accuracy and reliability of image inspection. In addition, the design of the fill light 207 also has an adjustment function, which can adjust the intensity and angle of the light according to the surface reflection characteristics of different parts to adapt to the inspection of parts with different materials, colors or surface characteristics.

[0035] Specifically, a receiving trough 208 is installed on the opposite side of pusher 1 204, pusher 2 205 and pusher 3 206. The receiving trough 208 is installed on the main frame 101 of the conveyor line. The receiving trough 208 can effectively receive the unqualified parts pushed out by pusher 1 204, preventing them from falling or mixing with the qualified parts on the conveyor belt 102, thereby realizing the automatic sorting and collection of unqualified products. The modular design of the receiving trough 208 makes it easy to disassemble and clean, and can quickly deal with the accumulation of unqualified parts, ensuring the continuous and efficient operation of the production line. Through the setting of the receiving trough 208, the detection and sorting processes are seamlessly connected, further improving the degree of production automation, reducing the necessity of manual intervention, and effectively improving the overall efficiency of the production line and the processing speed of unqualified products.

[0036] Specifically, the side inspection device 1 201, the side inspection device 2 202, the pusher 1 204, the pusher 2 205 and the pusher 3 206 are all equipped with a detector 209. The detector 209 is installed on the material blocking plate 105. The detectors 209 are all located on the same side. The detector 209 can detect in real time whether the material has arrived at the designated position and send a signal to the control system to ensure the smooth progress of the inspection and sorting process, effectively prevent the occurrence of empty load detection, and thus improve the efficiency and accuracy of the inspection.
