Description

Technical Field

[0001] This utility model relates to the field of automatic detection technology, and in particular to an automatic detection device for flat parts. Background Technology

[0002] In the industrial production field, the flatness quality inspection of parts is a key step in ensuring the final performance and assembly accuracy of products.

[0003] In the field of industrial automation inspection, industrial cameras, with their high-precision image acquisition and analysis capabilities, have become core equipment for parts quality inspection. However, when faced with parts requiring multi-plane inspection, existing automated inspection equipment typically can only inspect a single plane or a fixed direction, making it difficult to achieve simultaneous coverage of multiple key planes. If a part has multiple planes to be inspected, traditional solutions often require multiple inspection devices to complete full-dimensional quality verification through a pipeline-style sequential inspection. This model not only significantly increases equipment procurement costs and workshop floor space but also prolongs the inspection cycle and reduces overall production efficiency due to the transfer and positioning of parts between multiple devices. Furthermore, multi-device collaborative inspection may also affect the stability of inspection accuracy due to the accumulation of positioning errors between devices, further restricting the improvement of production efficiency and quality control levels.

[0004] In view of the above-mentioned technical problems, this application provides a novel automatic detection device for flat surfaces of parts, which realizes one-stop detection of multiple flat surfaces of parts, effectively reduces the number of detection equipment required, greatly shortens the detection process, and thus significantly improves the overall detection efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automatic part plane detection device, which aims to solve the technical problem that the same part plane detection device cannot detect multiple planes, resulting in low detection efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic part planar inspection device includes a base frame, a turntable and a turntable drive device mounted on the base frame, and multiple placement slots evenly spaced along the circumference of the turntable. A first inspection station, a first-stage part box, a second inspection station, a second-stage part box, a third inspection station, and a third-stage part box are sequentially arranged along the Y-direction on the base frame. A first industrial camera is mounted on the base frame corresponding to the first inspection station, facing the positive X-direction. A second industrial camera is mounted on the base frame corresponding to the second inspection station, facing the negative X-direction. A third industrial camera is mounted on the base frame corresponding to the third inspection station, vertically upwards. A support frame is mounted on the base frame, and a nozzle holder and a nozzle holder drive device are mounted on the support frame. A first nozzle, a second nozzle, a third nozzle, and a fourth nozzle are arranged at equal intervals on the nozzle holder.

[0008] Furthermore, in the aforementioned automatic part plane detection device, the turntable drive device is a geared motor.

[0009] Furthermore, in the aforementioned automatic part plane detection device, a worktable is provided on the base frame, and the worktable is located on the side of the turntable facing outward.

[0010] Furthermore, in the aforementioned automatic part plane detection device, a safety light grating is provided on the base frame. The infrared beam emitted by the safety light grating is parallel to the X direction and tangent to the outer circumference of the turntable.

[0011] Furthermore, in the aforementioned automatic part plane detection device, the nozzle holder drive device includes a horizontal slide rail connected to the support, a horizontal slide plate slidably connected to the horizontal slide rail, a vertical slide rail slidably connected to the horizontal slide plate, and a drive motor mounted on the support; the main shaft of the motor is provided with a crank, the crank is rotatably connected to a connecting rod, and the connecting rod is connected to the vertical slide rail; the nozzle holder is connected to the vertical slide rail.

[0012] Furthermore, in the aforementioned automatic part plane detection device, a transfer table and a transfer table drive device for driving the transfer table to rotate are also provided on the base frame downstream of the third part box.

[0013] Furthermore, in the aforementioned automatic part plane detection device, the turntable drive device is a rotary cylinder.

[0014] Furthermore, in the aforementioned automatic part plane detection device, a fifth suction nozzle is also provided on the suction nozzle frame at the same interval, and a blister packaging machine is also provided on the base frame.

[0015] Beneficial effects: This utility model provides an automatic part plane detection device, which has at least the following advantages compared with the prior art:

[0016] This invention, by setting up a first, second, and third inspection station, and respectively arranging a first, second, and third industrial camera along three different directions, enables the same equipment to inspect three different planes of a part. Compared to existing inspection equipment that can only inspect parts in a single direction, the technical solution proposed in this invention significantly improves the efficiency of planar part inspection. In this invention, the turntable has multiple storage slots evenly spaced along its circumference. Combined with the circumferential rotation of the turntable drive device, this facilitates continuous loading of parts by the operator, while simultaneously providing continuous feeding to the first suction nozzle. As the operator continuously places parts into empty storage slots at a fixed station, the turntable simultaneously transports the loaded parts sequentially to the first suction nozzle, ensuring the smooth operation of subsequent processes such as inspection and sorting, and improving production efficiency.

[0033] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0034] Please see Figures 1 to 7 This utility model provides an automatic detection device for the plane of a part. The accompanying drawings are for illustrative purposes only and are not proportional to actual products. The drawings only depict structures relevant to the innovation of this application; some conventional structures are not specifically shown. The terms "first," "second," etc., used herein are merely different names for similar structures for ease of explanation and are not intended to limit this application. For ease of explanation, some directional terms are unavoidably used herein, but these directional terms are not intended to limit this application. The term "multiple" as used herein refers to a quantity of two or more; since the number of structures referred to is not the inventive point, it is not specifically limited. For ease of observation, Figure 2 and Figure 3 The protective shield 18 is not shown.

[0035] The X and Y directions defined in this article are merely for ease of explanation and not intended to limit this utility model, because in practical applications, even if the coordinate system is changed, the essence of the technical solution will not change.

[0036] The automatic part planar inspection device includes a base frame 1, on which a turntable 2 and a turntable drive device (not visible from the perspective of the attached drawing) are mounted. Multiple storage slots 21 are evenly spaced along the circumference of the turntable 2. A first inspection station 31, a first-stage product box 41, a second inspection station 32, a second-stage product box 42, a third inspection station 33, and a third-stage product box 43 are sequentially arranged along the Y-direction on the base frame. A first industrial camera 51 is mounted on the base frame corresponding to the first inspection station, facing the positive X-direction. A second industrial camera 52 is mounted on the base frame corresponding to the second inspection station, facing the negative X-direction. A third industrial camera 53 is mounted on the base frame corresponding to the third inspection station. Figure 3 The actual viewpoint observed is of the ring light source of industrial camera 53, with the third industrial camera pointing vertically upwards. A bracket 19 is mounted on the base, on which a nozzle holder 70 and a nozzle holder drive mechanism (described in detail below) are mounted. A first nozzle 71, a second nozzle 72, a third nozzle 73, and a fourth nozzle 74 are arranged at equal intervals on the nozzle holder. The aforementioned first, second, and third industrial cameras can inspect three planes of the part. The nozzle holder drive mechanism is used to drive the nozzle holder to move vertically and horizontally along the Y direction.

[0037] There are several ways to achieve turntable rotation; as a preferred option, the turntable drive device is a geared motor (not visible from the perspective of the attached diagram). The output shaft of the geared motor is vertically upward and coaxial with the turntable. The geared motor converts its high speed into high torque output through a gear reduction mechanism, which can stably drive the turntable to rotate at a uniform speed. In addition, the geared motor can flexibly adjust the rotation speed of the turntable according to the actual inspection conditions of the parts (such as camera exposure time, image processing speed, etc.).

[0038] like Figure 2 and Figure 3 As shown, the base frame 1 is further provided with a worktable 11, which is located on the side of the turntable facing outwards. The worktable facilitates operation by the operator. For example, the parts to be inspected are placed on the worktable, and the operator sits on the side of the worktable facing outwards, placing the parts one by one into the storage slot of the turntable.

[0039] Please continue reading. Figure 2 and Figure 3Furthermore, a safety light curtain 12 is installed on the base frame. The infrared beam emitted by this safety light curtain is parallel to the X-direction and tangent to the outer circumference of the turntable 2. When the operator holds a part and inserts it into the turntable's loading slot for loading, the hand will block the infrared beam of the safety light curtain. The light curtain immediately triggers a sensing signal and sends it back to the control system. Upon receiving the signal, the control system quickly issues a command to stop the turntable drive device (i.e., the geared motor), and the turntable stops precisely, avoiding the risk of collision between the hand and the rotating parts. After the operator finishes loading the part and removes their hand to a safe area, the infrared beam of the safety light curtain is restored, and the control system then commands the geared motor to restart, driving the turntable to continue operating at a preset rhythm. When the turntable drive device pauses, the nozzle holder drive device also pauses; when the turntable drive device resumes movement, the nozzle holder drive device also resumes movement, thus ensuring that the movement of the nozzle holder and the rotation of the turntable are always matched.

[0040] The control system mentioned above can be a combination of PLC and computer. The PLC primarily handles real-time control tasks. For example, the PLC can precisely control the turntable drive according to a pre-set program, ensuring the turntable rotates stably at a specific speed. If the safety light curtain detects an anomaly, it will react quickly, stopping the turntable to ensure operator safety. The computer, on the other hand, focuses on data processing, decision-making, and human-machine interaction. The computer can receive various data collected by the PLC and data detected by various industrial cameras, such as part inspection results and equipment operating status, and perform in-depth analysis and processing of this data. For instance, the computer can use pre-set algorithms to analyze part images captured by industrial cameras to determine whether the parts are qualified and to identify their specific defective category. Since the control system is a standard feature of automatic inspection equipment, and this application does not seek protection for the control system, its structure and principles will not be specifically described here.

[0041] Please see Figure 5 and Figure 6 Furthermore, the nozzle holder drive device includes a horizontal slide rail 63 connected to the bracket 19, a horizontal slide plate 65 slidably connected to the horizontal slide rail, a vertical slide rail 67 slidably connected to the horizontal slide plate, and a drive motor 60 mounted on the bracket; the motor's main shaft is equipped with a crank 61, which is rotatably connected to a connecting rod 62, which is connected to the vertical slide rail; the nozzle holder is connected to the vertical slide rail. In practical applications, the horizontal slide plate 65 is slidably connected to the horizontal slide rail 63 via a horizontal slider 64, and the vertical slide rail 67 is slidably connected to the horizontal slide plate 65 via a vertical slider 66.

[0042] The rotation of the drive motor 60 causes the crank 61 to rotate, which in turn drives the connecting rod 62. Because the crank and connecting rod are rotatably connected, the connecting rod will displace in both the horizontal and vertical directions. The vertical displacement of the connecting rod is achieved by the vertical slide rail moving vertically relative to the horizontal slide plate, while the horizontal displacement is achieved by the horizontal slide plate moving horizontally relative to the horizontal slide rail. Since the vertical slide rail is mounted on the horizontal slide plate, its motion trajectory actually includes both vertical and horizontal displacement. Because the vertical slide rail is connected to the nozzle holder, the nozzle holder and nozzle can also move in both the vertical and horizontal directions, ultimately achieving the transfer of the part. In other words, the movement of the nozzle holder is actually a composite motion of horizontal movement in the Y-direction and vertical lifting / lowering.

[0043] Please see Figure 2 and Figure 3 Furthermore, a transfer platform 34 and a transfer platform drive device 341 for driving the transfer platform to rotate are also provided on the base frame downstream of the third product box 43. In practical applications, after the fourth suction nozzle transfers the part from the third inspection station to the transfer platform, the transfer platform drive device drives the transfer platform to rotate around the vertical axis by a certain angle. Adjusting the part to a certain angle here ensures that the part is at a suitable angle when entering the next process, thereby ensuring the smooth progress of subsequent operations.

[0044] Preferably, the transfer platform drive device 341 is a rotary cylinder. The rotary cylinder responds quickly, completing the rotation of the transfer platform in a short time, reducing the dwell time of parts during the transfer process. Furthermore, the rotary cylinder has a relatively simple structure, fewer parts, a low probability of failure, and is relatively easy to inspect and repair even when maintenance is required.

[0045] Furthermore, a fifth suction nozzle 75 is also provided on the nozzle holder at the same intervals (e.g., Figure 5 As shown), a blister packaging machine 9 is also installed on the base frame (e.g. Figure 2 and Figure 3 (As shown). Blister packaging machines are existing technology, and this application does not aim to propose a new blister packaging machine; therefore, its specific structure will not be described in detail here. In practical applications, the blister packaging machine 9 is equipped with a blister packaging belt 91 (as shown). Figure 2 and Figure 3As shown in the attached diagram, the blister packing belt has several support cavities (not visible from the perspective of the attached diagram) for placing parts. The fifth suction nozzle is used to transfer parts, which have been angled and adjusted on the transfer table, into the support cavities on the blister packing belt. The conveying mechanism of the blister packing machine (e.g., belt drive or roller drive) drives the blister packing belt forward step by step, with each movement corresponding to the distance between two adjacent support cavities, synchronized with the working cycle of the fifth suction nozzle. The parts in the support cavities are then delivered to the packaging station of the blister packing machine for packaging. Therefore, by incorporating the fifth suction nozzle and the blister packing machine, qualified parts can be automatically packaged, further improving production efficiency.

[0046] In practical applications, the first, second, third, fourth, and fifth suction nozzles are connected to a vacuum generator (not shown in the figure), and the vacuum on and off of each nozzle can be controlled individually.

[0047] To facilitate understanding, the following is a brief description of the work process:

[0048] (1) The operator loads the parts to be inspected one by one into the storage slots of the turntable from the side facing outwards. Each time a part is placed, the turntable rotates past the position of one storage slot.

[0049] (2) The nozzle frame drive device drives the nozzle frame to move in the positive Y direction (during this process, the nozzle frame not only moves horizontally, but also goes through rising and falling in sequence). The first nozzle transfers a part from the storage slot on the turntable to the first inspection station; the second nozzle transfers the part originally located at the first inspection station to the second inspection station (if the inspection result of the first inspection station is unqualified, the vacuum system of the corresponding nozzle of the part is closed during the transfer process, and the part falls into the first product box); the third nozzle transfers the part originally located at the second inspection station to the third inspection station (if the inspection result of the second inspection station is unqualified, the vacuum system of the corresponding nozzle of the part is closed during the transfer process, and the part falls into the second product box); the fourth nozzle transfers the part originally located at the third inspection station to the intermediate transfer platform (if the inspection result of the third inspection station is unqualified, the vacuum system of the corresponding nozzle of the part is closed during the transfer process, and the part falls into the third product box); the fifth nozzle transfers the part on the intermediate transfer platform that has completed the angle adjustment to the supporting cavity of the blister packaging belt on the blister packaging machine. Then the nozzle holder drive mechanism moves the nozzle holder in the negative Y direction (during this process, in addition to horizontal movement, the nozzle holder will also experience rising and falling sequentially), and the nozzle holder returns to its original position. Figure 2 As shown, the nozzle holder completes one work cycle. Since all nozzles are mounted on the same nozzle holder, the transfer of each component occurs synchronously.

[0050] (3) The parts placed in the support cavity of the blister packaging belt are further packaged by the blister packaging machine.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of the present utility model, and all such modifications or substitutions should fall within the protection scope of the present utility model.
