Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a product coplanarity testing device. Background Technology

[0002] Coplanarity is a key parameter that measures whether multiple surfaces of a product lie on the same plane. For example, the leads of electronic components and the pads on a PCB board must meet coplanarity requirements to ensure assembly reliability. In the field of electronics manufacturing, coplanarity directly affects soldering quality and circuit performance, therefore its accurate measurement is crucial.

[0003] Traditional testing methods rely on tools such as dial indicators and feeler gauges, which are manual and inefficient, and can easily damage products due to contact measurement. These methods are not only time-consuming, but also prone to errors due to human factors, thus affecting product quality and production efficiency.

[0004] Existing machine vision inspection methods using cameras can quickly detect the coplanarity of individual products, significantly improving inspection efficiency. Machine vision systems capture images of products using high-resolution cameras and analyze surface geometry using advanced image processing algorithms to accurately determine coplanarity. This method not only reduces human intervention but also greatly lowers the risk of product damage. However, this method requires manual placement of the product under the camera for inspection, followed by removal, resulting in slow loading and unloading speeds and hindering continuous inspection. Furthermore, for products with special structural shapes, the angle of the product on the horizontal plane needs to be adjusted to suit the camera's inspection position. Currently, relying on manual angle adjustment leads to missed detections, low inspection efficiency, and difficulty in effectively meeting the coplanarity detection requirements.

[0036] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0037] like Figure 1-8 The image shows a product coplanarity testing device according to this embodiment. This device is suitable for coplanarity testing of products in the fields of electronic components and mechanical parts. The device has a conveying route, and loading stations, rotating stations, testing stations, and unloading stations are sequentially arranged along the conveying route. Products are conveyed via this route, so that the products pass through the loading station, rotating station, testing station, and unloading station in sequence.

[0038] The aforementioned equipment includes a first carrier 1, a rotating device, a detection device, a conveying mechanism 7, a third carrier 3, a coplanarity detector 6, and a feeding device 5. The first carrier 1 is arranged corresponding to the feeding station. The top surface of the first carrier 1 is provided with a positioning groove 9 adapted to the product. The first carrier 1 carries the product through the positioning groove 9 and positions the product to restrict the product's movement in the horizontal direction.

[0039] The aforementioned rotating device, corresponding to a rotating workstation arrangement, includes a second support member 2 and a rotating actuator 21. The top surface of the second support member 2 also has a positioning groove 9 adapted to the product. The first support member 1 carries the product through this positioning groove 9 and positions the product to restrict its horizontal movement. The aforementioned rotating actuator 21 is driven by the second support member 2 to drive the second support member 2 to rotate around its own central axis, thereby rotating the product on it. In this embodiment, the rotation angle of the second support member 2 is 90° or 180°. The central axis of the second support member 2 extends vertically. The aforementioned rotating actuator 21 is a conventional drive motor.

[0040] The aforementioned third carrier 3 is arranged at the corresponding inspection station and is also equipped with a positioning groove 9 adapted to the product. The third carrier 3 carries the product through the positioning groove 9 and positions the product to restrict its horizontal movement. The aforementioned coplanarity detector 6 is arranged at the inspection station, located above the third carrier 3, and has a detection end facing the third carrier 3 to perform coplanarity detection on the product located in the positioning groove 9 on the third carrier 3. In this embodiment, the coplanarity detector 6 is preferably a laser camera. The laser camera captures an image of the product and uses image processing algorithms to analyze the geometric features of the surface to determine the coplanarity of the product.

[0041] The aforementioned unloading device 5 is arranged at the unloading station to receive products. The unloading device 5 consists of two unloading bins 51 arranged side by side. A discharge port is formed at the top of the unloading bin 51, through which products can enter the unloading bin 51. Of the two unloading bins 51, one unloading bin 51 receives good products, and the other unloading bin 51 receives defective products.

[0042] In this embodiment, the aforementioned conveying mechanism 7 is arranged between the loading station, the rotating station, the inspection station, and the unloading station to transport products from the loading station through the rotating station, the inspection station, and the unloading station in sequence, thereby realizing the operation of the products at each station. Under the control of the central processing unit, when the conveying mechanism 7 moves the product to the unloading station, the conveying mechanism 7 is used to transport the product from the inspection station to one of the unloading bins 51 according to the detection result of the coplanarity detector 6.

[0043] In the specific structural design, at least two conveying routes are arranged in parallel to enable the synchronous conveying of multiple products. Correspondingly, a loading station, a rotating station, and a unloading station are arranged on each conveying route. A variable-pitch station is arranged between the rotating station and the inspection station on each conveying route. The device in this embodiment includes a fourth carrier 4 and a variable-pitch driver 41. The fourth carrier 4 is arranged corresponding to each variable-pitch station. The top surface of the fourth carrier 4 is also provided with a positioning groove 9 adapted to the product. The fourth carrier 4 carries the product through the positioning groove 9 and positions the product to limit the product's movement in the horizontal direction. The fourth carriers 4 on each of the above-mentioned conveying routes are relatively movable to each other, having an initial position and a close-up position. The aforementioned variable-pitch driver 41 is used to drive the relative movement between each fourth carrier 4 to switch back and forth between the initial position and the close-up position.

[0044] In this embodiment, when in the aforementioned initial position, the aforementioned conveying mechanism 7 is used to synchronously convey the products on each conveying route from the second carrier 2 of the rotating station to the fourth carrier 4 of the variable-pitch station, and when in the aforementioned closing position, the conveying mechanism 7 is used to synchronously convey the products on each conveying route from the fourth carrier 4 of the variable-pitch station to the third carrier 3 of the inspection station. Specifically, in the initial position, the distance between the positioning grooves 9 on each fourth carrier 4 at the variable-pitch station is the same as the distance between the positioning grooves 9 on each second carrier 2 at the rotating station. When in the closing position, the distance between the positioning grooves 9 on each fourth carrier 4 at the variable-pitch station is the same as the distance between the positioning grooves 9 on each third carrier 3 of the inspection station. A set of coplanarity detectors 6 is shared by the inspection stations on each conveying route. By changing the spacing between products at the variable-pitch station, each product can be within the detection range of the detection end of the same set of coplanarity detectors 6 when it is transported to the detection station. This facilitates the transport of products between the rotary station, the variable-pitch station, and the detection station, and simplifies the overall structure.

[0045] In this embodiment, two conveying routes are arranged according to actual needs. In the specific structural design, of the two fourth carrier members 4 on the two conveying routes, the first is fixedly arranged, and the second slides on a slide rail to move closer to or away from the first. The track-changing driver is a linear drive mechanism to drive the second to move back and forth, thereby moving closer to or away from the first. It should be noted that the first of the aforementioned fourth carrier members 4 can slide on a slide rail to move closer to or away from the second. A corresponding track-changing driver is arranged to drive the first to move. Furthermore, when this embodiment has three or more conveying routes, a track-changing driver is arranged corresponding to each fourth carrier member 4 to drive each fourth carrier member 4 to move, thereby realizing the movement of each fourth carrier member 4 between the initial position and the approaching position.

[0046] The aforementioned conveying mechanism 7 includes a movable seat 71 and a reciprocating drive device 73. The reciprocating drive device 73 is connected to the movable seat 71 to drive the movable seat 71 to reciprocate in a preset direction. The preset direction is the vertical direction and the conveying route direction. By driving the movable seat 71 to move back and forth along the conveying route direction, the movable seat 71 can reciprocate between the loading station, the rotating station, the variable pitch station, and the unloading station. The reciprocating drive device 73 is a conventional device of the prior art and can be an integrated device capable of driving the movable seat 71 to move in both the vertical and vertical directions and the conveying route direction. Alternatively, it can include a first driver for driving the movable seat 71 to rise and fall, and a second driver for driving the movable seat 71 to move back and forth in the conveying route direction. The first driver and the second driver are connected in a drive-connected manner.

[0047] Four sets of vacuum suction cup assembly arrays 72 are arranged on the aforementioned movable base 71. Each set of vacuum suction cup assembly arrays 72 includes a long arm 721 and vacuum suction cup assemblies 722. The vacuum suction cup assemblies 722 are fixed on the long arm 721. Each long arm 721 has a vacuum suction cup assembly 722 arranged corresponding to each conveying path for gripping or releasing products. Air channels are arranged on the long arm 721 corresponding to each vacuum suction cup assembly 722, allowing each vacuum suction cup assembly 722 on the long arm 721 to operate independently. The gripping or releasing operation of each vacuum suction cup assembly 722 is controlled by the air channels, and the vacuum suction cup assemblies 722 in each set of vacuum suction cup assembly arrays 72 are arranged at intervals. The aforementioned vacuum suction cup assembly 722 is a conventional device in the prior art, and its working principle is common knowledge. The movement of the movable base 71 drives the movement of the aforementioned four sets of vacuum suction cup assembly arrays 72. The movable seat 71 moves up and down, thereby driving the vacuum suction cup assembly array 72 to move up and down, so as to approach or move away from the loading station, rotating station, variable distance station, and unloading station, thereby adsorbing or releasing the products at the loading station, rotating station, variable distance station, and unloading station.

[0048] The system comprises the following components: a first set of vacuum suction cup arrays 72, which moves with the movable base 71 between a loading station and a rotary station, thereby gripping products from the loading station and moving them to the rotary station; a second set of vacuum suction cup arrays 72, which moves with the movable base 71 between a rotary station and a variable-pitch station, thereby gripping products from the rotary station and moving them to the fourth support member 4 in the initial position of the variable-pitch station; a third set of vacuum suction cup arrays 72, which moves with the movable base 71 between a variable-pitch station and a detection station, thereby gripping products from the fourth support member 4 in the approach position of the variable-pitch station and moving them to the detection station; and a fourth set of vacuum suction cup arrays 72, which moves with the movable base 71 between a detection station and a unloading station, thereby gripping products from the variable-pitch station and moving them to the detection station. Specifically, according to the actual structural design, the spacing between the vacuum suction cup components 722 in the third group of vacuum suction cup component array 72 and the spacing between the vacuum suction cup components 722 in the fourth group of vacuum suction cup component array 72 are consistent with the spacing between the positioning grooves 9 of the third support members 3 in the close-up position. The spacing between the vacuum suction cup components 722 in the first group of vacuum suction cup component array 72 and the spacing between the vacuum suction cup components 722 in the second group of vacuum suction cup component array 72 are consistent with the spacing between the positioning grooves 9 of the third support members 3 in the initial position.

[0049] In this embodiment, the product can be manually loaded into the positioning groove 9 of the first carrier 1 in a preset state. Furthermore, to achieve automated operation, a vertical vibration track 8 is arranged on one side of the first carrier 1 for sequentially conveying the product in a preset posture. The preset posture is preferably the product's front side facing upwards. One end of the vertical vibration track 8 is aligned with the positioning groove 9 on the first carrier 1, thereby sequentially conveying the product into the positioning groove 9 of the first carrier 1. The vertical vibration track 8 is a conventional component of the prior art, and its interior forms a conveying channel 81 adapted to the product. A vibratory feeder, also of the prior art, is also used to screen the product in the preset posture and convey it to the vertical vibration track 8.

[0050] In practical use, the products are arranged in a preset posture along the linear vibration track 8 and sequentially conveyed into the positioning grooves 9 on the first carrier 1. The first set of vacuum suction cup assembly array 72 synchronously grasps the products on each of the first carrier 1 and moves them to the positioning grooves 9 on the second carrier 2 at the rotating station. The second carrier 2 is driven to rotate to adjust the angle of the products on the horizontal plane. The second set of vacuum suction cup assembly 722 then grasps the products on each of the second carrier 2 and moves them to the positioning grooves 9 on each of the fourth carrier 4 at the variable pitch station, which are in their initial positions. The variable pitch driver 41 drives each of the fourth carrier 4 to move closer together to change the distance between the products. The third set of vacuum suction cup assembly array 72 then grasps the products on each of the fourth carrier 4 at the moved-to-close position and moves them to the positioning grooves 9 on the third carrier 3 at the inspection station. Each product is inspected by the coplanarity detector 6. After inspection, the fourth set of vacuum suction cup assembly array 72 grasps the products on each of the third carrier 3 at the inspection station and moves them to the unloading station. Based on the detection results of the coplanarity detector 6, the position of the fourth set of vacuum suction cup assemblies 722 above the unloading device 5 is controlled to release each product into the corresponding unloading bin 51, thereby separating good and defective products. In this method, products can be sequentially conveyed from the loading station to the rotating station, the inspection station, and the unloading station, enabling automatic entry and exit from the inspection station and achieving continuous operation. The rotating device allows adjustment of the product's angle on the horizontal plane to accommodate the detection position requirements of the coplanarity detector 6. Several conveying routes are arranged to simultaneously convey multiple products, achieving batch inspection. The variable-pitch driver 41 changes the distance between products on each of the fourth carrier components 4, ensuring that each product is within the detection range of a single set of coplanarity detectors 6 at the inspection station, thus enabling simultaneous inspection of multiple products using a single set of coplanarity detectors 6. The combination of these methods achieves continuous product inspection, reduces manual intervention, increases automation, improves inspection efficiency, saves costs, and effectively meets the coplanarity inspection requirements of products.
