Description

Technical Field

[0001] This invention relates to the field of production equipment technology, and in particular to a center bolt detection device. Background Technology

[0002] Center bolts are widely used in various mechanical parts, and the dimensional inspection of their internal and external shapes is particularly important during their processing and testing. As a connecting component, the quality and precision of center bolts directly affect the performance and safety of the entire product. Automated testing equipment can ensure that the dimensions, shape, and material properties of each center bolt meet design requirements, thereby improving the overall product quality.

[0003] Chinese invention patent CN114324376B discloses an autonomous quantitative product testing device and method, including a machine tool. A feeding / discharging assembly is bolted to the top of the machine tool. A gripping assembly is bolted to the outer side of one end of the feeding / discharging assembly, and a housing is bolted to the outer side of the gripping assembly. A positioning assembly is bolted to one side of the feeding / discharging assembly, a detection assembly is bolted to one side of the positioning assembly, a measuring assembly is bolted to the inner wall of the housing, and a PLC controller is bolted to the surface of the housing.

[0056] The discharge conveyor belt 800 is fixed to the right end of the frame 100 and is used to transport the center bolt to the designated position for subsequent processing. The discharge conveyor belt 800 is provided with two sections, a qualified placement belt and an unqualified placement belt, which can separate qualified and unqualified products for separate transport.

[0057] The turntable assembly 300 includes a stepper motor 310, a rotating disk 320, a hook 321, and a product base 330;

[0058] The stepper motor 310 is fixed to the bottom of the frame 100 and is connected to the rotating disk 320 through a cam divider to achieve precise angle control of the rotating disk 320.

[0059] The rotating disk 320 is circular and connected to the output shaft of the stepper motor 310, and is used to realize product station switching;

[0060] The product holder 330 has six units, which are evenly fixed at the edge of the rotating disk 320 and are used to hold the center bolt products.

[0061] The shooting assembly 400 includes a shooting bracket 410, a support and adjustment frame 420, a camera 430, and a telecentric camera 440;

[0062] The shooting bracket 410 has an L-shaped structure and is fixed on the frame 100;

[0063] The support adjustment frame 420 is fixed on the horizontal section of the shooting bracket 410 and is used to adjust the height and angle of the camera 430 and the telecentric camera 440 according to the detection requirements.

[0064] The camera 430 and the telecentric camera 440 are arranged vertically and fixed below the support adjustment frame 420. The camera 430 is used to photograph the overall appearance of the center bolt product, and the telecentric camera 440 is used to accurately measure the detailed dimensions of the center bolt product.

[0065] The go gauge assembly 500 includes a cylinder 510, a go gauge bracket 511, a linear guide rail 520, a go gauge 530, a slide cylinder 540, and a rangefinder 560.

[0066] The cylinder 510 is fixed to the frame 100 via the gob gauge bracket 511 and is used to drive the gob gauge 530 to move up and down to measure the inner diameter of the product; the linear guide rail 520 is fixed to the telescopic end of the cylinder 510; the gob gauge 530 is fixed to the linear guide rail 520; the slide cylinder 540 is fixed to the upper end of the gob gauge bracket 511 and is used to fix the center bolt to be inspected to ensure measurement accuracy; the rangefinder 560 is fixed to the upper end of the gob gauge bracket 511 and located below the slide cylinder 540, and is used to measure dimensions.

[0067] The dotting assembly 600 includes a pressure head bracket 610, a pressure head cylinder 620, a pressure head 630, and a pad block 640;

[0068] The pressure head bracket 610 has an L-shaped structure and is fixed on the frame 100;

[0069] The pressure head cylinder 620 is fixed to the upper end of the pressure head bracket 610, and the extension end of the pressure head cylinder 620 is fixed with a pressure head 630, which is used to press the product against the pressure head cylinder 620.

[0070] The pad 640 is fixed on the horizontal section of the pressure head bracket 610 and located below the product seat 330. It is used to support the center bolt and prevent displacement during the dotting process.

[0071] A safety light curtain is fixed on the frame 100. The safety light curtain consists of a pair of transmitters and receivers. The transmitters emit infrared beams, and the receivers receive the beams. When an object or person enters the light curtain area, it blocks the beam, preventing some or all of the light from being received by the receiver. By creating a light curtain barrier, when a person approaches or crosses this light curtain, the safety light curtain can detect it and immediately stop the operation of the relevant equipment to prevent injury. The rangefinder 560 is used for measuring the size of the product and is preferably a laser displacement sensor; these are all existing technologies and will not be described in detail here.

[0072] In actual operation, the steps of this embodiment are as follows:

[0073] Step 1: The product is conveyed by the conveying component 200 and placed on the product seat 330 on the rotating disk 320. The product is put into the material pit. The imaging component 400 starts to work. The telecentric camera 440 and the first camera 430 measure the external dimensions of the product respectively. The support adjustment frame 420 adjusts the imaging position of the telecentric camera 440 and the first camera 430 to detect the size data of the hexagonal head at the bottom of the product, the thickness and diameter of the flange, the thickness and width of the hexagonal head, and the diameter and height of the top of the product.

[0074] Step 2: After the imaging component 400 completes the detection of the product's shape data, the rotating disk 320 rotates 60 degrees clockwise to transfer the product to the go gauge component 500. The slide cylinder 540 begins to press down to fix the product, and the cylinder 510 begins to move, driving the go gauge 530 up and down. At the same time, the inner hole of the product is measured by the rangefinder 560. The rangefinder 560 uses laser displacement sensing to determine whether the product is qualified or unqualified.

[0075] Step 3: After completing the measurement of the go gauge assembly 500, the rotating disk 320 rotates 60 degrees clockwise and begins to enter the workstation of the marking assembly 600. Products that have passed the inspection in the previous stations will be marked by the pressure head 630, otherwise they will not be marked. When the product is transferred to the position of the marking assembly 600, the pressure head cylinder 620 is activated to press the product against the pad 640 through the pressure head 630. The pad 640 provides support, and the pressure head cylinder 620 drives the pressure head 630 to mark the product.

[0076] Step 4: After the workstation with the dotting component 600 completes the dotting, the product has completed the inspection of all workstations. The rotating disk 320 rotates 60 degrees clockwise, and the material transfer robot 700 starts to pick up the material and place it on the discharge conveyor belt 800. That is, the unqualified products detected at different stations are selected and placed on the unqualified placement belt, and all qualified products from all stations are placed on the same qualified placement belt.

[0077] Step 5: After the discharge conveyor belt 800 is full, qualified and unqualified products are removed manually or by a robotic arm. The rotating disc 320 rotates 180 degrees, and the conveyor component 200 discharges the material to continue the previous cycle.

[0078] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0079] The conveyor assembly 200 places the product on the product holder 330, which then rotates sequentially through the imaging assembly 400, the gauge assembly 500, and the marking assembly 600, significantly saving time and space. The marking of the product by the pressure head 630 allows for efficient tracking of the inspection status of each product. The camera 430 and the telecentric camera 440 in the imaging assembly 400 inspect the dimensions of various parts of the product, greatly improving the accuracy and precision of the inspection and reducing repetitive manual inspections and errors. The material handling robot 700 picks up the product and places it on the discharge conveyor belt 800, and then sorts it to separate qualified and unqualified products.

[0080] Example 2

[0081] In order to ensure stable delivery of products to the rotating disk 320 and improve the flexibility of this device, this application proposes the following technical solution to address the above-mentioned technical problems:

[0082] Please see Figures 8 to 9 The conveying assembly 200 includes a motor 210, a belt 211, a column 212, a motor 220, a belt 221, and a column 222.

[0083] The first motor 210 and the second motor 220 are respectively fixed to the left end of the frame 100, and are used to drive the first belt 211 and the second belt 221 to rotate.

[0084] The first column 212 and the second column 222 are respectively fixed to the middle part of the frame 100 at the front and rear;

[0085] The belt 1 211 and belt 2 221 are respectively sleeved on the output end of motor 1 210, the output end of column 1 212 and motor 2 220, and the outside of column 2 222. The belt 1 211 and belt 2 221 both pass through the protective cover 110 and the background plate 120.

[0086] The belt 1 211 and belt 2 221 are slidably connected inside the fixed arc plate 1 and fixed arc plate 2 respectively, and are supported by the fixed arc plate 1 and fixed arc plate 2 respectively. The belt 1 211 and belt 2 221 are arranged in parallel and are used to clamp and transport products.

[0087] The rotating disk 320 is evenly provided with a plurality of hooks 321. The hooks 321 are semi-circular ring structures and correspond one-to-one with the product seats 330. They are used to hook products from the conveying assembly 200 and place them on the product seats 330.

[0088] like Figure 11 The diagram shows the state of belt 211 and belt 221 of this application when clamping and conveying the product. The solid arrows in the diagram represent their respective rotation directions. Belt 211 and belt 221 rotate in opposite directions and can clamp and convey the product to the rotating disk 320 position.

[0089] This application achieves a continuous and stable conveying process through the operation of belt 1 211 and belt 2 221 and the clamping action between them, avoiding the intermittency and instability of manual feeding, thereby improving conveying efficiency. At the same time, it improves conveying efficiency and positioning accuracy, reduces labor costs and safety risks, and further optimizes the spatial layout and enhances the flexibility of the production line.

[0090] Example 3

[0091] Considering that only one side of the product can be photographed when it is conveyed to the conveyor assembly 200, the single shooting surface has blind spots and cannot achieve 360° all-round shooting and inspection, resulting in inaccurate measurement results, this application proposes the following technical solution to address the above-mentioned technical problems, specifically:

[0092] Please see Figures 9 to 10 Multiple clamping rings 230 are evenly fixed on the outer side of the belt 221. The clamping rings 230 are semi-circular ring structures used to clamp the product.

[0093] The clamping ring 230 includes a telescopic rod 231, an arc plate 232, and a rotating roller 233;

[0094] The telescopic rod 231 is fixed to the outside of the belt 221; the arc plate 232 is fixed to the telescopic end of the telescopic rod 231; multiple rotating rollers 233 are rotatably connected to the inner wall of the arc plate 232, and the rotating rollers 233 are evenly arranged around the circumference of the arc plate 232, and the rotating rollers 233 are in contact with the product.

[0095] This embodiment, by setting up a clamping ring 230 and a rotating roller 233, enables the product to be rotated and conveyed under the combined action of the belt 211, the clamping ring 230, and the rotating roller 233 (i.e., the product can rotate during the conveying process). This allows for multi-directional imaging when the product is conveyed to the shooting position, avoiding measurement blind spots. The multi-directional imaging method can more comprehensively capture the product's shape features, improving the accuracy and comprehensiveness of the inspection. At the same time, the design of the clamping ring 230 and the rotating roller 233 allows the equipment to adapt to products of different shapes and sizes. Since the product can rotate, regardless of its shape, it can ensure that every part is fully photographed, thereby enhancing the versatility and adaptability of the equipment, making it suitable for the inspection of a variety of products.

[0096] Example 4

[0097] Considering that before the product is hooked out by the hook ring 321, when the product moves to the hooking position, it may pre-disengage from belt one 211 and belt two 221 (i.e., clamping ring 230), which may cause the product to shift position, making it impossible for the hook ring 321 to pull the product out in time or for the product to be accurately placed in the product holder 330, this application proposes the following technical solution to the above-mentioned technical problems, specifically:

[0098] Please see Figures 11 to 12 Multiple flexible plates 240 and 250 are evenly fixed on the inner sides of belt 211 and belt 221, respectively. Flexible plate 240 corresponds to clamping ring 230, and flexible plate 250 is used to cooperate with flexible plate 240 to prevent the product from shifting position.

[0099] This application, by setting flexible plate one 240 and flexible plate two 250, enables the product to be slightly offset by the action of flexible plate one 240 and flexible plate two 250 before and during hooking out by hook ring 321, so that belt one 211 and belt two 221 can be slightly offset when hook ring 321 hooks out the product (e.g. Figure 12As shown, the solid arrows represent the offset direction of the two belts, and the hollow arrows represent the rotation direction of the rotating disk 320. This offset is the same as the direction of the rotating disk 320, thereby compensating for the positional offset of the product that may be caused by inertia or insufficient friction. This ensures that the product can be smoothly and accurately carried out from the belt 1 211 and belt 221 by the hook 321 and smoothly placed into the product seat 330, so that the product can be smoothly transported to the product seat 330.

[0100] Example 5

[0101] To ensure the product falls accurately and precisely into the product holder 330, preventing skewing and mispositioning, this application proposes the following technical solution to address the aforementioned technical problem:

[0102] Please see Figures 12 to 16 A rubber sleeve 340 is fixed on the product seat 330 for product positioning and to prevent product damage; the rubber sleeve 340 has a ring structure and its interior has a conical inclined surface structure, including a conical iron plate 341 and a fixing block 342.

[0103] The conical iron sheet 341 is provided in multiple groups, arranged vertically. The radial dimension of each group of conical iron sheets 341 decreases from bottom to top. Each group of conical iron sheets 341 is formed by stacking multiple conical iron sheets 341 individually to accommodate products of different sizes.

[0104] The fixing block 342 has a conical structure with a through hole in the middle. It is placed upside down and fixed to the bottom of the rubber sleeve 340 in a detachable manner to fix the bottom of the product.

[0105] This embodiment effectively solves the problem of product deviation and inaccurate positioning during transportation by setting a rubber sleeve 340. The rubber sleeve 340 provides a buffering effect, ensuring the stability of the product during transportation. By controlling the number of individual tapered iron pieces 341 inserted, the inner diameter of the rubber sleeve 340 can be controlled, making it suitable for positioning products of different sizes and specifications. At the same time, the tapered iron pieces 341 arranged vertically can form a slightly gradient inclined surface, which guides the product as it falls into the rubber sleeve 340. Meanwhile, the cylindrical structure in the fixing block 342 can fit against the side wall of the product, achieving precise positioning of the product, improving the accuracy and efficiency of detection, reducing detection errors caused by product deviation or inaccurate positioning, and improving the overall detection quality.

[0106] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0107] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
