Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically to an inductor coil appearance inspection device. Background Technology

[0002] An inductor is a device that works based on the principle of electromagnetic induction. When current flows through a wire, a certain electromagnetic field is generated around the wire, and the wire itself will induce an effect on other wires within this electromagnetic field.

[0003] For small inductors, during production, semi-finished products such as... Figure 2 As shown, the middle part is an inductor coil, which is generally about 5mm in diameter. The two ends are connected to conductive sheets. The coil is then encapsulated in plastic. Finally, the excess conductive sheets at both ends of the outer shell are cut off to obtain the finished product. Before encapsulating the inductor coil, it is necessary to perform an appearance inspection to ensure that there are no defects on the surface and that the dimensions meet the requirements. Otherwise, the finished product after encapsulation will not meet the requirements. Traditionally, the inspection is carried out manually under a high-magnification glass, which is a relatively inefficient method. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an inductor coil appearance inspection device.

[0005] The specific technical solution is as follows: an inductor coil appearance inspection device, including a first lead screw slide, a clamping mechanism, a camera module and a three-dimensional laser profile measuring instrument. The clamping mechanism is connected to the slider of the first lead screw slide. The clamping mechanism is used to clamp the inductor coil. Under the drive of the first lead screw slide, the clamping mechanism can make linear movements.

[0006] The clamping mechanism includes a first connecting plate, a cylinder mounting plate, a corner pressing cylinder, a carrier plate, and a pressure plate. The first connecting plate is fixedly connected to the slider of the first lead screw slide. The carrier plate is fixed to one end of the first connecting plate. The cylinder mounting plate is also fixedly connected to the first connecting plate. The corner pressing cylinder is connected to the cylinder mounting plate. The pressure plate is connected to the end of the corner pressing cylinder and rotates and moves up and down with the corner pressing cylinder. Both the carrier plate and the pressure plate are provided with strip-shaped cutouts, the size of which corresponds to the size of the inductor coil.

[0007] Several camera modules are provided above and below the movement path of the clamping mechanism for taking pictures and detecting the front and back of the inductor coil. At the same time, a three-dimensional laser profile measuring instrument is also provided above the movement path of the clamping mechanism for measuring the profile dimensions of the inductor coil.

[0008] Furthermore, there are two of each of the first lead screw slides and the clamping mechanism, and they are arranged in a one-to-one correspondence, with the two first lead screw slides arranged in parallel.

[0009] Furthermore, a second lead screw slide is also provided on the two first lead screw slides. The three-dimensional laser profile measuring instrument is fixedly connected to the slider of the second lead screw slide. Driven by the second lead screw slide, the three-dimensional laser profile measuring instrument can reciprocate above the movement path of the two clamping mechanisms.

[0010] Furthermore, it also includes a feeding mechanism, which comprises a third lead screw slide and a gripping mechanism. The gripping mechanism is connected to the slider of the third lead screw slide. The gripping mechanism includes a back plate, a linear guide rail, a movable plate, a telescopic cylinder, and a vacuum suction head. One side of the back plate is connected to the slider of the third lead screw slide, and the other side is connected to the movable plate via the linear guide rail. The linear guide rail is vertically arranged. The back plate and the movable plate can slide up and down correspondingly. A telescopic cylinder is fixed on the movable plate. The cylinder body of the telescopic cylinder is fixedly connected to the movable plate, and the piston rod end of the telescopic cylinder is fixedly connected to the back plate. By extending and retracting the cylinder, the back plate and the movable plate slide relative to each other. A vacuum suction head is also provided at the bottom of the movable plate.

[0011] Furthermore, it includes a feeding mechanism, which also includes a third lead screw slide and the gripping mechanism, and its structure is the same as that of the feeding mechanism.

[0012] Furthermore, it also includes a pallet transfer mechanism, which specifically includes a synchronous belt linear motion mechanism, a first ball screw module, a motor, a suction cup mounting plate, and a suction cup. The synchronous belt linear motion mechanism specifically includes a base plate, a synchronous belt, synchronous pulleys, a stepper motor, linear guides, and a screw module mounting base. The synchronous belt is correspondingly sleeved on a set of synchronous pulleys, and the synchronous pulleys correspond to the stepper motor. The screw module mounting base is fixedly connected to the synchronous belt. There are two linear guides, which are arranged in parallel and installed in a direction parallel to the synchronous belt. The sliders of the two linear guides are fixedly connected to the bottom of the screw module mounting base. The forward or reverse movement of the synchronous belt drives the screw module mounting base to reciprocate along the direction of the linear guides.

[0013] The first ball screw module is vertically mounted on the screw module mounting base. The motor is connected to the first ball screw module. The suction cup mounting plate is connected to the screw nut of the first ball screw module and moves synchronously with the screw nut. Multiple suction cups are mounted on the suction cup mounting plate.

[0014] Furthermore, both the feeding mechanism and the unloading mechanism are equipped with pallet adjustment mechanisms at corresponding positions. The pallet adjustment mechanism includes a fourth lead screw slide, a base, a side plate, a second ball screw, and a support plate. The direction of the fourth lead screw slide is perpendicular to that of the third lead screw slide. The base is installed on the slider of the fourth lead screw slide. The second ball screw is vertically installed on the base. The support plate is fixedly connected to the lead screw nut of the second ball screw. A motor is also correspondingly provided on the second ball screw. The motor drives the lead screw nut of the second ball screw to move up and down, thereby driving the support plate to move up and down. The base is also equipped with a vertically arranged side plate to facilitate the stacking of multiple pallets.

[0015] Furthermore, a sorting mechanism is also provided at one end of the first lead screw slide near the unloading mechanism. The sorting mechanism includes a mounting frame, a second cylinder, a slide rail, a slider, and a gripping mechanism. The second cylinder is horizontally mounted on the mounting frame. The back plate of the gripping mechanism is fixedly connected to the piston rod of the second cylinder. The back plate of the gripping mechanism is fixedly connected to the slider. The slide rail is correspondingly connected to the slider. The length direction of the slide rail corresponds to the extension and retraction direction of the second cylinder, and the slide rail is also fixedly connected to the mounting frame.

[0016] Compared with existing technologies, the technical solution proposed in this utility model sets up a corresponding clamping mechanism with open top and bottom. The coil to be tested is placed on the clamping mechanism and fixed. Then, driven by the linear module, it passes through the upper and lower parts of the high-magnification camera module to take pictures and detect the front and back of the coil. Then, it is also subjected to dimensional detection by a three-dimensional laser profile measuring instrument. This can ensure detection accuracy and greatly improve efficiency compared with manual inspection. In addition, corresponding loading and unloading mechanisms are set up to realize automatic loading and unloading, further reducing manpower and improving efficiency. Furthermore, pallet transfer mechanism and pallet adjustment mechanism are set at corresponding positions of the loading and unloading mechanisms. This allows multiple pallets to be stacked at the loading position for material retrieval. After the inductor coil on a pallet has been tested, the empty pallet is moved to the receiving position by the pallet transfer mechanism to receive the qualified inductor coil. This eliminates the need for frequent pallet replacement and saves more manpower. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0026] Please see Figure 1 To address the problems existing in the relevant prior art, this utility model proposes an inductor coil appearance inspection device, including a first lead screw slide 1, a clamping mechanism 2, a camera module 3, and a three-dimensional laser profile measuring instrument 4. The clamping mechanism 2 is connected to the slider of the first lead screw slide 1. The clamping mechanism 2 is used to clamp the inductor coil. Under the drive of the first lead screw slide 1, the clamping mechanism 2 can make linear movements.

[0027] Specifically, in the above scheme, the first lead screw slide is an existing labeling module used to control the device to perform linear motion, and is equipped with a corresponding drive motor. In this embodiment, the clamping mechanism is installed on the slider of the first lead screw slide, so that the clamping mechanism can complete linear motion and the motion speed can be freely controlled.

[0028] Please see Figure 3The clamping mechanism 2 includes a first connecting plate 201, a cylinder mounting plate 202, a corner pressing cylinder 203, a carrier plate 204, and a pressure plate 205. The first connecting plate 201 is fixedly connected to the slider of the first lead screw slide 1. The carrier plate 204 is fixed to one end of the first connecting plate 201. The cylinder mounting plate 202 is also fixedly connected to the first connecting plate 201. The corner pressing cylinder 203 is connected to the cylinder mounting plate 202. The pressure plate 205 is connected to the end of the corner pressing cylinder 203 and rotates and moves up and down with the corner pressing cylinder 203. Both the carrier plate 204 and the pressure plate 205 are provided with strip-shaped cutouts, and the size of the cutouts corresponds to the size of the inductor coil.

[0029] Specifically, in the above scheme, the rotating pressing cylinder 203 rotates at a specific angle of 90 degrees. The pressure plate 205 is connected to the piston rod of the rotating pressing cylinder. Driven by the rotating pressing cylinder, the pressure plate 205 rises and rotates 90 degrees about the piston rod of the rotating pressing cylinder. At this time, the inductor coil can be placed on the carrier plate 204, and the coil corresponds to the cutout position on the carrier plate 204, so that the camera module 3 can take pictures and detect the back of the inductor coil from below. After placement, the rotating pressing cylinder resets and drives the pressure plate 205 to reach above the inductor coil and move downward to cooperate with the carrier plate 204 to clamp the inductor coil. At the same time, the cutout on the pressure plate 205 also corresponds to the position of the coil, so that the camera module 3 can take pictures and detect the front of the inductor coil from above.

[0030] Several camera modules 3 are provided above and below the movement path of the clamping mechanism 2. Specifically, in this embodiment, a high-magnification camera is selected. The specific camera can be selected according to the size of the product, which is common knowledge in the field. The camera module located above the movement path is used to take pictures and detect the top of the inductor coil, and the camera module located below the movement path is used to take pictures and detect the top of the inductor coil. At the same time, a three-dimensional laser profile measuring instrument 4 is also provided above the movement path of the clamping mechanism 2 to measure the profile size of the inductor coil. The three-dimensional laser profile measuring instrument selected here is a mature module on the market. The size data of the part to be measured can be obtained when the object passes through the shooting position of the measuring instrument. This is a simple application of existing equipment.

[0031] The specific operation of the above scheme is as follows: First, control the rotating pressing cylinder to separate the carrier plate from the pressure plate. Then, place the inductor coil on the carrier plate. Next, rotate the pressing cylinder to reset and drive the pressure plate to cooperate with the carrier plate to press the inductor coil tightly. The clamping mechanism, driven by the first lead screw slide, passes through the detection positions of multiple camera modules in sequence to complete the photographic detection of the inductor coil. At the same time, the dimensional measurement of the inductor coil is completed by the three-dimensional laser contour measuring instrument. The vision system confirms whether the inductor coil is qualified based on the photographs and the detected data. This system is a mature vision inspection system and is existing technology, so it will not be described in detail here. After detecting one inductor coil, the clamping mechanism 2 returns to the initial position driven by the first lead screw slide to complete the above repeated operation to detect another inductor coil.

[0032] Please continue reading. Figure 1 The first lead screw slide 1 and the clamping mechanism 2 are both two in number and are set one-to-one. The two first lead screw slides are set in parallel. Through the above setting, two working paths can be realized, which can effectively improve the working efficiency. A second lead screw slide 5 is also provided on the two first lead screw slides 1. The second lead screw slide is also an existing annotation module. The three-dimensional laser profile measuring instrument 4 is connected to the slider of the second lead screw slide 5. Driven by the second lead screw slide 5, the three-dimensional laser profile measuring instrument 4 can move back and forth above the movement path of the two clamping mechanisms 2.

[0033] Specifically, one clamping mechanism first completes the loading and clamping, and then the corresponding first lead screw slide moves the inductor coil. At this time, the 3D laser profile measuring instrument moves above the movement path of the clamping mechanism, thus realizing profile measurement. Simultaneously, another clamping mechanism loads the material. After the first clamping mechanism completes its detection, the other clamping mechanism completes its loading. Thus, the clamping mechanism moves forward under the drive of the corresponding first lead screw slide, and the 3D laser profile measuring instrument moves above the movement path of the clamping mechanism under the drive of the second lead screw slide, also realizing profile measurement. Through the above setup, one 3D laser profile measuring instrument can measure the inductor coils on two paths, which can effectively save the cost of one 3D laser profile measuring instrument without affecting efficiency.

[0034] Please see Figure 1 and 4It also includes a feeding mechanism, which comprises a third lead screw slide 6 and a gripping mechanism 7. The gripping mechanism 7 is connected to the slider of the third lead screw slide 6. The gripping mechanism 7 includes a back plate 701, a linear guide rail 702, a movable plate 703, a telescopic cylinder 704, and a vacuum suction head 705. One side of the back plate 701 is connected to the slider of the third lead screw slide 6, and the other side is connected to the movable plate 703 via the linear guide rail 702. The linear guide rail 702 is vertically arranged, and the back plate 701 and the movable plate 703 can slide up and down accordingly. A telescopic cylinder 704 is fixed on the movable plate 703. The cylinder body of the telescopic cylinder 704 is fixedly connected to the movable plate 703, and the piston rod end of the telescopic cylinder 704 is fixedly connected to the back plate 701. By extending and retracting the piston rod of the telescopic cylinder 704, the back plate 701 and the movable plate 703 are driven to slide relative to each other. A vacuum suction head 705 is also provided at the bottom of the movable plate 703. The vacuum suction head is a commonly used device for suctioning parts under negative pressure. It is used here for simple application, which is to pick up the inductor coil or put down the inductor coil that has been picked up.

[0035] Specifically, in the above scheme, the third lead screw slide 6 is also a standard module, used to drive and control the gripping mechanism to perform linear motion. The clamping mechanism 2 moves from one end to the other under the drive of the first lead screw slide, defining the initial position as the loading station. A tray is placed at any position below the stroke of the third lead screw slide 6, and the inductor coil is placed on the tray. In this way, the third lead screw slide drives the gripping mechanism 7 to move above the tray first, and the telescopic cylinder 704 extends to drive the vacuum suction head to move downward, correspondingly sucking up the inductor coil in the tray. Then the telescopic cylinder 704 retracts, and at the same time, the third lead screw slide 6 drives the clamping mechanism to move to the loading station. Above, the rotating pressing cylinder drives the pressure plate to rotate and separate from the carrier plate. At the same time, the telescopic cylinder 704 extends, driving the vacuum suction head 705 to descend and place the sucked inductor coil on the carrier plate. Then, the vacuum suction head retracts under the action of the telescopic cylinder and returns to the tray to pick up materials again under the action of the third lead screw slide. Meanwhile, the rotating pressing cylinder drives the pressure plate to press the inductor coil placed on the carrier plate and moves forward under the action of the first lead screw slide. In this way, the detection is completed by multiple camera modules and a 3D laser contour measuring instrument. The above settings can complete the automatic feeding operation, which can save more labor.

[0036] Please see Figure 1 It also includes a feeding mechanism, which includes a third lead screw slide 6 and a gripping mechanism 7. Its structure is the same as that of the feeding mechanism. The following is a detailed description of its use:

[0037] When the first lead screw slide drives the clamping mechanism to pass the camera module and the 3D laser profile measuring instrument in sequence and then stops, this position is defined as the unloading station. At the same time, an empty receiving tray is placed on the side of the machine. The unloading mechanism is set between the unloading station and the receiving tray, so that the gripping mechanism of the unloading mechanism can move back and forth above the unloading station and above the receiving tray under the drive of the corresponding third lead screw slide. When the inductor coil that has passed the measurement by the camera module and the 3D laser profile measuring instrument moves to the unloading station under the drive of the first lead screw slide, the rotating pressing cylinder drives the pressure plate to release the inductor coil. The third lead screw slide of the unloading mechanism drives the gripping mechanism 7 to move to the top of the unloading station. The telescopic cylinder of the gripping mechanism extends and drives the vacuum suction head to move downward to pick up the inductor coil on the carrier plate. Then the telescopic cylinder retracts, and at the same time the third lead screw slide drives the gripping mechanism to move to the top of the receiving tray. The telescopic cylinder extends again, drives the vacuum suction head to fall and place the qualified inductor coil on the receiving tray.

[0038] Please see Figure 1 and Figure 5 Both the loading and unloading mechanisms are equipped with pallet adjustment mechanisms 8 at corresponding positions. Each pallet adjustment mechanism 8 includes a fourth lead screw slide 801, a base 802, a side plate 803, a second ball screw 804, and a support plate 805. The fourth lead screw slide 801 is perpendicular to the third lead screw slide 6. The fourth lead screw slide is a standard module available on the market and also includes a corresponding drive motor. The base 802 is mounted on the slider of the fourth lead screw slide 801. The second ball screw 804 is vertically mounted on the base 802. The second ball screw is also a commercially available module used to drive and control the connection to the lead screw nut. The parts achieve linear movement, and the specific structural details are not described here. The support plate 805 is fixedly connected to the screw nut of the second ball screw 804. The second ball screw 804 is also equipped with a motor 806. The motor 806 drives the screw nut of the second ball screw 804 to move up and down, thereby driving the support plate 805 to move up and down. The base 802 is also equipped with vertically arranged side plates 803 to facilitate the stacking of multiple pallets 9. When a pallet is placed on the support plate 805, the two sides correspond to the side plates of the two objects. Multiple pallets 9 can be stacked on the support plate 805.

[0039] In use, corresponding to the tray adjustment mechanism at the feeding mechanism position, multiple trays 9 containing inductor coils are stacked on the support plate 805. Driven by the movement of the feeding mechanism, the gripping mechanism first grips and feeds one row of inductor coils. After one row of inductor coils is fed, the fourth lead screw slide moves the tray 9 laterally, so that the stroke of the third lead screw slide of the feeding mechanism corresponds to that of the other row of inductor coils, completing the feeding and unloading of the other row of inductor coils. The operation is repeated until all the inductor coils on a tray 9 are fed and unloaded. At this time, the empty tray is removed, and then the second ball screw drives the support plate 805 to rise, so that the next tray 9 reaches the specified picking height. Then the above feeding and unloading work is repeated.

[0040] Corresponding to the pallet adjustment mechanism at the unloading mechanism position, an empty pallet is first placed on the support plate. Then, the fourth lead screw slide adjusts the pallet position so that the placement position of one row of inductor coils on the pallet corresponds to the stroke of the third lead screw slide of the unloading mechanism. At the same time, the second ball screw adjusts the pallet to the designated height for receiving. Then, the gripping mechanism reciprocates under the drive of the third lead screw slide and sequentially grips the inductor coils at the unloading station and places them onto the pallet. After one row is placed, the fourth lead screw slide adjusts and drives the placement position of another row of empty inductor coils to correspond to the stroke of the third lead screw slide. This allows loading of another row of placement positions. The operation is repeated until the pallet is completely loaded with the tested inductor coils. At this time, an empty pallet is stacked on the pallet again. Then, the fourth lead screw slide and the second ball screw readjust the height so that the empty pallet is at the designated position for receiving.

[0041] Please see Figure 1 and Figure 6It also includes a pallet transfer mechanism 10, which specifically includes a synchronous belt linear motion mechanism 101, a first ball screw module 102, a motor 103, a suction cup mounting plate 104, and a suction cup 105. The synchronous belt linear motion mechanism 101 is a mechanism capable of linear reciprocating motion, specifically including a base plate 1011, a synchronous belt 1012, synchronous pulleys 1013, a stepper motor 1014, a linear guide rail 1015, and a screw module mounting base 1016. The synchronous belt 1012 is correspondingly sleeved on a set of synchronous pulleys 1013, and the synchronous pulleys 1013 are correspondingly connected to the stepper motor 1014. The mounting base 1016 is fixedly connected to the timing belt 1012. There are two linear guides 1015, which are arranged in parallel and installed in the same direction as the timing belt 1012. The sliders of the two linear guides 1015 are fixedly connected to the bottom of the screw module mounting base 1016. The timing belt is driven to move forward or backward by a motor, which in turn drives the screw module mounting base 1016 to move back and forth along the direction of the linear guides. The timing belt 1012 is installed on the side of the feeding mechanism and the unloading mechanism, so that the screw module mounting base can move back and forth on the side of the feeding mechanism and the side of the unloading mechanism.

[0042] The first ball screw module 102 is vertically mounted on the screw module mounting base 1016. The motor 103 is correspondingly connected to the first ball screw module 102 and is used to drive the fourth ball screw module 102 to work. The suction cup mounting plate 104 is connected to the screw nut of the first ball screw module 102 and moves synchronously with the screw nut. Multiple suction cups 105 are mounted on the suction cup mounting plate 104. The ball screw module is a commonly used linear standard module, which is the prior art. The linear movement of the screw nut can be achieved by rotating the screw. Specifically, in this embodiment, the first screw module is vertically set. The motor 103 drives the screw of the first screw module to rotate forward or backward, thereby driving the screw nut to move upward or downward. The suction cup mounting plate is correspondingly connected to the screw nut and moves upward or downward synchronously.

[0043] The pallet transfer mechanism is mainly used to laterally transfer empty pallets from the loading position to the receiving position after loading. The specific working process is as follows: After the loading mechanism has finished loading all the inductor coils in a pallet on the pallet adjustment mechanism, the first lead screw module moves above the loading mechanism under the drive of the synchronous belt linear motion mechanism. Then, the first ball screw module 102 drives the suction cup 105 to move downward to contact the empty pallet and pick it up. The first ball screw module 102 then drives the suction cup 105 to move upward and moves to the pallet adjustment mechanism corresponding to the unloading mechanism under the drive of the synchronous belt linear motion mechanism. The first ball screw module 102 drives the suction cup 105 to move downward again to place the empty pallet on the pallet adjustment mechanism. Through the above working method, whenever a pallet on the pallet adjustment mechanism corresponding to the loading mechanism is loaded, the pallet transfer mechanism picks up the empty pallet and places it on the pallet adjustment mechanism corresponding to the unloading mechanism through the above steps. This reduces the frequency of manually changing pallets on the pallet adjustment mechanism and also improves the utilization rate of the pallets.

[0044] Please see Figure 1 and Figure 7 The first lead screw slide is also equipped with a sorting mechanism 11 near the unloading mechanism. The sorting mechanism 11 includes a mounting frame 1101, a second cylinder 1102, a slide rail 1103, a slider 1104, and a gripping mechanism 7. The second cylinder 1102 is horizontally mounted on the mounting frame 1101. The gripping mechanism 7 is fixedly connected to the piston rod of the second cylinder with its back plate. The gripping mechanism 7 is the same as the gripping mechanism of the loading and unloading mechanisms. Specifically, the back plate of the gripping mechanism in the sorting mechanism is fixedly connected to the slider 1104. The slide rail 1103 is correspondingly set to the slider 1104. The length direction of the slide rail 1103 corresponds to the extension and retraction direction of the second cylinder 1102. The slide rail 1103 is also fixedly connected to the mounting frame. The extension and retraction of the second cylinder drives the gripping mechanism corresponding to the piston rod of the second cylinder to reciprocate. The stroke of the gripping mechanism passes above the stroke of the clamping mechanism.

[0045] Specifically, when the camera module 3 or the 3D laser contour measuring instrument 4 detects a defect or non-compliant size of the inductor coil, the first lead screw slide moves the clamping mechanism below the stroke of the gripping mechanism of the sorting mechanism. The telescopic cylinder 704 extends, driving the vacuum suction head 705 to descend and pick up the inductor coil on the clamping mechanism. Then the telescopic mechanism retracts, and at the same time, the second cylinder 1102 extends, driving the gripping mechanism to move to the NG material discharge position. The NG material discharge position can be any position where the gripping mechanism leaves the clamping mechanism. Specifically, in this embodiment, the NG material discharge position is below the position of the gripping mechanism 7 when the second cylinder 1102 extends. With the above settings, non-compliant products can be effectively sorted.

Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
