Description

Technical Field

[0001] This invention relates to the field of capacitor production and testing equipment technology, specifically to an automatic insertion and testing device and method for horn-shaped electrolytic capacitors. Background Technology

[0002] Horn-shaped electrolytic capacitors are widely used electronic components in circuits. During their production, the capacitor's pin positions, appearance, and other specifications must be inspected. After passing inspection, they are accurately inserted into a dedicated test rack for subsequent aging tests. Currently, this insertion process typically relies on manual labor or semi-automated equipment, resulting in low efficiency, high labor intensity, and potential product damage. While some automated equipment has emerged, most employ a single-channel operation mode. The entire process from product transport and inspection to insertion is executed serially; the next product must wait until the previous one completes all processes, hindering production cycle speed and failing to meet the demands of large-scale, high-efficiency production. Therefore, there is an urgent need for automated equipment capable of multi-station parallel operation, significantly improving inspection and insertion efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an automatic insertion and testing device for horn-shaped electrolytic capacitors. By setting up parallel workstations, this invention solves the technical problems of low operating efficiency and slow production cycle time in existing equipment. Furthermore, this invention also provides an automatic insertion and testing method applied to this equipment.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An automatic insertion and testing device for horn-shaped electrolytic capacitors includes: A conveying device is used to transport products along the conveying direction and to divert products; A blocking mechanism, located on one side of the output end of the conveying device, is used to selectively block products; A transfer device is arranged in front of the output end of the conveying device, and has a first transfer gripper and a second transfer gripper that can reciprocate along the conveying direction. The image acquisition and inspection mechanism, located above the transfer device, is used to acquire images of the products held by the transfer device. The rotary clamping mechanism, located above the transfer device, is used to clamp the product and drive it to rotate horizontally based on the feedback signal from the image acquisition and detection mechanism. The flipping clamping device, located in front of the transfer device, is used to receive the product transferred by the transfer device and flip the product over; The receiving clamping mechanism is located in front of the flipping clamping device and is used to receive the flipped product; The feeding insert device is located above the receiving clamping mechanism and is used to pick up the product from the receiving clamping mechanism and transfer the product to place it. The capacitance test bracket is located below the feeding insertion device and is used to support the products placed by the feeding insertion device.

[0005] Furthermore, the conveying device includes a main track and at least two branch tracks, the input end of each branch track is connected to the main track, and each branch track is equipped with a position sensor; the material blocking mechanism includes a material blocking drive and a material blocking block connected to the output end of the material blocking drive.

[0006] Furthermore, the transfer device includes a transfer traverse mechanism, on which at least two first transfer grippers and at least two second transfer grippers are arranged side by side, each first transfer gripper corresponding to the output end of a diversion track.

[0007] Furthermore, the equipment also includes two lifting mechanisms, which are respectively located on the left and right sides of the transfer device. The material blocking mechanism, the image acquisition and detection mechanism, and the rotary clamping mechanism are all installed on the lifting mechanisms.

[0008] Furthermore, the rotary clamping mechanism includes a rotary drive and a rotary gripper, the rotary gripper being connected to the rotary drive and having grippers.

[0009] Furthermore, the flipping clamping device includes a flipping drive and two flipping clamps. The two flipping clamps are connected to the flipping drive to achieve synchronous flipping, and the flipping clamps have grippers. Furthermore, there are at least two receiving clamping mechanisms, each receiving clamping mechanism including a receiving clamping member having grippers.

[0010] Furthermore, the feeding insertion device includes a feeding transverse mechanism, a feeding lifting mechanism disposed on the feeding transverse mechanism, and two feeding clamping members disposed side by side on the feeding lifting mechanism, the feeding clamping members having grippers.

[0011] Furthermore, the capacitance test rack includes a horizontal traversing mechanism and two test racks arranged side by side on the horizontal traversing mechanism, with multiple insertion positions on the test racks.

[0012] An automatic insertion detection method for horn-shaped electrolytic capacitors, applied to the aforementioned equipment, includes the following steps: Step S1: The product is diverted and conveyed by the conveying device. The position sensor set on the diversion track detects the product arrival signal and drives the blocking block of the blocking mechanism to extend to block the next product, so as to realize the single-piece supply to the transfer station. Step S2: The current product is held by the first transfer clamp, and the image information of the product is acquired by the image acquisition and detection mechanism; Step S3: Move the first transfer gripper holding the product to below the rotary gripping mechanism, whereby the rotary gripping mechanism grips the product and drives the product to rotate horizontally to a predetermined position based on the acquired image information; Step S4: Transfer the rotated and adjusted product to the second transfer gripper, while the first transfer gripper returns to the transfer station to hold the next product and perform image acquisition; Step S5: The second transfer gripper transfers the product to the flipping gripper, which flips the product. Step S6: The receiving clamping mechanism receives the flipped product; Step S7: The feeding insertion device picks up the product from the receiving clamping mechanism and transfers the product to the capacitor test socket. Beneficial effects

[0013] This invention provides a multi-station withstand voltage testing device, which has the following advantages compared with the prior art: 1. By adopting a structure that matches the dual-diversion track with a dual-station transfer device, the simultaneous conveying, parallel detection, and synchronous processing of two products are achieved. While the first product is undergoing angle adjustment and flipping, the second product can begin image acquisition. The overlapping execution of the two operations significantly shortens the average processing cycle of a single product and multiplies the overall capacity of the equipment.

[0014] 2. The image acquisition and inspection mechanism works in conjunction with the rotating clamping mechanism to acquire a top-down view of the product and precisely adjust its horizontal angle based on image feedback, ensuring the product is in the correct posture before being inserted into the test rack. This adjustment mechanism avoids rack insertion failures caused by misaligned pins or poor appearance, thus improving the finished product yield.

[0015] 3. The equipment fully integrates all processes from product sorting, visual inspection, posture correction, flipping and handling to automatic rack insertion, forming a complete automated production line. Operators only need to load and unload materials, significantly reducing labor intensity.

[0016] 4. The material blocking mechanism, in conjunction with the position sensor, enables orderly single-piece supply of products, avoiding jamming and collisions. The dual lifting mechanisms, symmetrically positioned on both sides of the transfer device, house the material blocking, detection, and rotation functional modules. This rational layout ensures stability during high-speed operation. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] See Figures 1 to 12 This embodiment provides an automatic insertion and testing device for horn-shaped electrolytic capacitors, used to realize the automatic conveying, visual inspection, posture adjustment, and insertion process of capacitor products 100. All moving parts of the device can be controlled by a unified controller (such as a PLC). The device integrates a conveying device 1, a blocking mechanism 2, a transfer device 3, an image acquisition and detection mechanism 4, a rotating clamping mechanism 5, a flipping clamping device 6, a receiving clamping mechanism 7, a feeding insertion device 8, and a capacitor testing insert 9 on the frame.

[0021] like Figures 1 to 3 , Figure 7As shown in the figure, the conveying device 1 includes a main track 11 and two branch tracks 12. The input ends of the two branch tracks 12 are connected to the output end of the main track 11, forming a "Y"-shaped branching structure. Both the main track 11 and the branch tracks 12 can be linear conveyor belts. During operation, several products first enter the main track 11 for conveying, and then are branched and enter the two branch tracks 12 respectively. On the branch tracks 12, the products are arranged into individual pieces and conveyed forward in sequence. A position sensor 13 is provided on one side of the output end of each branch track 12 to detect whether the product has reached the predetermined gripping position. In front of the output end of the branch track 12, a blocking mechanism 2 is set up, consisting of a blocking drive 21 and a blocking block 22. The blocking drive 21 is a cylinder, and the blocking block 22 is fixed to the end of its piston rod. When the position sensor 13 detects that the current product has arrived, the controller can instruct the blocking drive 21 to drive the blocking block 22 to extend and block the next product, realizing the orderly supply of individual pieces to the transfer station.

[0022] like Figures 1 to 3 , Figures 5 to 6 As shown, the transfer device 3 is arranged in front of the output end of the conveying device 1. The main body of the transfer device 3 is a linear module driven by a motor to rotate a lead screw, which in turn moves a slide table, forming a transfer traverse mechanism 33. The movement direction of this traverse mechanism is parallel to the conveying direction of the diversion track 12. On the moving slide table of the transfer traverse mechanism 33, a mounting base is fixedly installed. On the base, two sets of identical first transfer grippers 31 and two sets of identical second transfer grippers 32 are mounted side by side. The two sets of first transfer grippers 31 respectively receive products from the two diversion tracks 12, while the two sets of second transfer grippers 32 are used to transfer the adjusted products. Both the first transfer grippers 31 and the second transfer grippers 32 are pneumatic gripper structures with integrated cylinders. The grippers are driven by the cylinders to clamp or release the products. It should be noted that the distance between the first transfer grippers 31 and the second transfer grippers 32 can be adjusted according to actual production needs.

[0023] like Figure 5 , Figure 7As shown, on the left and right sides of the transfer device 3, there are symmetrically structured lifting mechanisms 10. Each lifting mechanism 10 is a servo motor-driven lead screw module. The motor drives the lead screw to rotate, driving the moving seat to move vertically up and down along the guide rail. Each lifting mechanism 10's moving seat is independently equipped with a set of blocking mechanisms 2, image acquisition and detection mechanisms 4, and rotating clamping mechanisms 5, so that the above mechanisms are positioned above the transfer device 3 and can move vertically up and down. Each set of image acquisition and detection mechanisms 4 includes a high-resolution industrial camera and a ring light source, with its lens pointing vertically downwards, facing directly above the product held by the first transfer gripper 31 on the same side. Each set of rotating clamping mechanisms 5 includes a rotating drive 51 and a rotating gripper 52. The rotating drive 51 is a motor (such as a servo motor or stepper motor), whose output shaft is connected to the rotating gripper 52, driving the rotating gripper 52 to rotate 360 ​​degrees horizontally. The rotating gripper 52 is a pneumatic gripper structure integrated with a cylinder, which drives the gripper to open and close to clamp or release the product. Figure 14 As shown, the rotating gripper 52 is equipped with grippers 521 connected to a cylinder and a leveling block 522. The leveling block 522 is fixedly positioned directly above the grippers 521, and its length is greater than that of the grippers 521. The grippers 521 are used to hold the neck groove 101 on the outside of the capacitor product 100. The leveling block 522 is used to apply pressure to the insulating outer skin on the top of the product when it is gripped, pressing and leveling it to prevent the insulating outer skin from lifting and affecting subsequent plug-in testing. In this embodiment, when the rotating gripper 52 receives the product transferred from the first transfer gripper 31, the two grippers 521 of the rotating gripper 52 hold the neck groove 101 on the outside of the capacitor product 100, and the gripping position of the grippers 521 is adapted to the neck groove 101 on the outside of the product. The two grippers 521 grip and rotate the neck groove 101 on the outside of the product, achieving correct pin orientation adjustment while further tightening the housing, thereby improving the product's sealing performance.

[0024] The rotating gripper 52 clamps the neck groove 101 on the outside of the capacitor product 100 via the gripper 521. This design brings multiple synergistic technical benefits. First, the neck groove 101, as an inherent feature on the capacitor product 100 housing, provides the gripper 521 with a stable and repeatable precise positioning reference. Compared to clamping a smooth cylindrical housing, the gripping groove effectively prevents axial slippage or radial deflection of the product during high-speed horizontal rotation to adjust the angle, thus ensuring that the angle correction after visual inspection can be performed with high precision, significantly improving the alignment success rate of subsequent plug-in components. Second, during the process of gripping and rotating the neck groove 101, the gripper 521 applies a uniform clamping force along the circumference of the groove to the housing's closing part. This action, while rotating the product leads to the correct posture, is also equivalent to performing a circumferential tightening and verification of the sealing joint between the aluminum housing and the rubber stopper. This process helps eliminate gaps that may remain due to previous processes, further improving the sealing reliability of the capacitor product and preventing electrolyte leakage or drying out due to poor sealing during subsequent aging tests. Furthermore, the synchronous pressing of the top insulating outer sheath by the leveling block 522 above the gripper 521 completely eliminates insert failures caused by the insulating outer sheath lifting or shell misalignment, thus ensuring the continuity of automated production and the yield of finished products from the root. like Figures 1 to 3 , Figures 8 to 12As shown, a flipping clamping device 6 is arranged in front of the transfer device 3 to receive products transferred from the transfer device 3 and achieve a 180-degree flip. The flipping clamping device 6 mainly consists of a flipping drive 61 and two flipping clamping members 62 mounted on the same rotating shaft 63. The two flipping clamping members 62 are respectively arranged corresponding to two second transfer gripping members 32, and are used to simultaneously pick up products transferred by the two second transfer gripping members 32. The flipping drive 61 is a motor (such as a servo motor), and its output shaft is connected to the rotating shaft 63 through a synchronous pulley 64, which can precisely drive the two flipping clamping members 62 to rotate synchronously by 180 degrees, thereby flipping the two products simultaneously and sending them to the receiving position in front. The outer circumferential surface of the rotating shaft 63 is provided with a connecting portion 65 for the fixed connection of the flipping clamping member 62. The connecting portion 65 is recessed in the outer circumferential surface of the rotating shaft 63 and has several fixing holes. By designing the connecting portion 65 recessed in the outer circumferential surface of the rotating shaft 63, the flipping clamping member 62 can be stably connected to the rotating shaft 63, and the recessed structure limits the installation to prevent the flipping clamping member 62 from swaying left or right. Both flipping clamping members 62 are pneumatic gripper structures with integrated cylinders. The cylinders drive the grippers to open and close to clamp or release the product. In this embodiment, the flipping clamping device 6 can be fixed on the frame or fixed on a flipping lifting mechanism 66. The flipping lifting mechanism 66 is a lead screw module driven by a servo motor. The motor drives the lead screw to rotate, driving the moving frame to move vertically up and down along the guide rail. When the flipping clamping device 6 is fixed on the flipping lifting mechanism 66, the flipping clamping device 6 can be driven to lift and lower as a whole through the flipping lifting mechanism 66 to adjust the material transfer height, thereby meeting the production needs of products of different specifications.

[0025] Further forward of the flipping clamping device 6, two parallel receiving clamping mechanisms 7 are fixedly installed, their positions corresponding to the front release position of the flipping clamping member 62. Each receiving clamping mechanism 7 includes a receiving clamping member 71, which is a pneumatic gripper structure with an integrated cylinder. The cylinder drives the gripper to clamp or release, so as to pick up the flipped product and hold it briefly.

[0026] The feeding insertion device 8 is a conveying module mounted above the receiving clamping mechanism 7. Specifically, it includes a horizontal feeding transverse mechanism 81, which is a motor-driven lead screw module. The motor drives the lead screw to rotate, driving the slide table to move horizontally along the guide rail. A vertically downward feeding lifting mechanism 82 is provided on the slide table of the feeding transverse mechanism 81. The feeding lifting mechanism 82 is a cylinder-driven linear slide rail module. The extension and retraction of the cylinder piston rod drives the mounting plate to move up and down along the slide rail. Two feeding clamping components 83 are mounted side-by-side on the lower mounting plate of the feeding lifting mechanism 82. The feeding clamping components 83 are pneumatic gripper structures with integrated cylinders. The cylinder drives the grippers to open and close to clamp or release products, used to pick up products from the receiving clamping mechanism 7.

[0027] like Figures 1 to 3 as well as Figure 13 As shown, a capacitor test holder 9 is arranged on each of the left and right sides below the feeding insertion device 8. Each capacitor test holder 9 includes a horizontal traversing mechanism 91 parallel to the conveying direction and a test rack 92 mounted on it. The horizontal traversing mechanism 91 is a motor-driven lead screw module. The motor drives the lead screw to rotate, driving the test rack 92 to move horizontally along the guide rail. The test rack 92 is a fixture frame with multiple rows and multiple insertion positions 921. The horizontal traversing mechanism 91 drives the test rack 92 to move horizontally, so that the empty insertion positions 921 are aligned row by row with the material release position of the feeding clamping mechanism 83.

[0028] This embodiment also provides an automatic insertion detection method for horn-shaped electrolytic capacitors based on the above-mentioned equipment, the workflow of which is detailed below: Step S1: Several horn-shaped electrolytic capacitors to be tested are placed on the main track 11 of the conveying device 1 for transport. The products are diverted from the main track 11 and enter two diversion tracks 12 respectively. On the diversion tracks 12, the products are arranged into individual units and transported forward in sequence. When a product reaches the end of the diversion track 12, it will be detected by the position sensor 13, and the controller will then command the first transfer gripper 31 to prepare for gripping.

[0029] Step S2: The transfer traverse mechanism 33 moves backward (towards the conveyor device 1), causing the two first transfer grippers 31 to reach their respective picking positions. The cylinders of the first transfer grippers 31 drive the grippers to close and pick up the products. After clamping, the motors of the two lifting mechanisms 10 drive the lead screws to rotate, causing the moving base to descend. During this process, the stop drive 21 drives the stop block 22 to extend and block the next product. At the same time, the camera and light source of the image acquisition and detection mechanism 4 mounted on the moving base move closer to the products as they descend, taking top-down pictures of the two products simultaneously to detect the pin positions.

[0030] Step S3: After image acquisition, the transfer lateral mechanism 33 moves forward (away from the conveyor 1), precisely transferring the first transfer gripper 31 directly below the two rotating grippers 52 of the rotating clamping mechanism 5. The cylinders of the rotating grippers 52 drive the jaws 521 to close, clamping the neck groove 101 on the outside of the product, and the first transfer gripper 31 is then released. During the clamping process, the leveling block 522 located directly above the jaws 521 presses and flattens the insulating outer skin on the top of the product to prevent the insulating outer skin from lifting. Based on the angular deviation analyzed from the image, the controller controls the rotating drive 51 to rotate the rotating grippers 52 holding the product horizontally at the corresponding angle, correcting the product to a standard posture. At the same time, during the rotation, the clamping force of the jaws 521 further tightens the shell, improving the product's sealing performance.

[0031] Step S4: The transfer traverse mechanism 33 moves backward again to the reset position, causing the two second transfer grippers 32 to move below the rotary gripper 5. The cylinders of the second transfer grippers 32 drive the grippers to close, receiving the adjusted product from the rotary gripper 52. At the same time, the first transfer gripper 31 located behind also returns to the material handling station, synchronously performing the gripping and image acquisition of the next set of products, realizing parallel operation.

[0032] Step S5: The motor-driven lead screw of the transfer traverse mechanism 33 rotates, causing the slide to move forward again, simultaneously transferring the two second transfer grippers 32 holding the calibrated products to the handover station of the flipping gripper 6. The cylinders of the two flipping grippers 62 simultaneously drive the jaws to close, receiving products from the two second transfer grippers 32 respectively. Subsequently, the motor-driven shaft of the flipping drive 61 rotates 180 degrees, causing the two flipping grippers 62 to rotate synchronously, flipping the two products simultaneously and sending them to the receiving position in front.

[0033] Step S6: The receiving clamping parts 71 of the two receiving clamping mechanisms 7 operate simultaneously, driving their respective grippers to close and pick up the products flipped over by the two flipping clamping parts 62. After receiving the products, the grippers of the flipping clamping parts 62 immediately release, and the flipping drive 61 drives the rotating shaft to rotate 180 degrees in the opposite direction, so that the two flipping clamping parts 62 return to the rearward-facing handover position, waiting for the next receiving.

[0034] Step S7: The motor-driven lead screw of the infeed transverse mechanism 81 rotates, coordinating with the cylinder of the infeed lifting mechanism 82 to move the infeed clamp 83 directly above the receiving clamp 71. The cylinder of the infeed lifting mechanism 82 extends, pushing the infeed clamp 83 downward, and the cylinder of the infeed clamp 83 drives the grippers to close and pick up the product. Then, the cylinder of the infeed lifting mechanism 82 retracts, and the motor-driven lead screw of the infeed transverse mechanism 81 rotates, moving the infeed clamp 83 transversely above the target capacitor test bracket 9. Simultaneously, the motor-driven lead screw of the horizontal transverse mechanism 91 rotates, moving the insertion hole position of the test rack 92 into place. The cylinder of the infeed lifting mechanism 82 extends again, accurately inserting the product pins into the insertion positions 921 of the test rack 92. The cylinder of the infeed clamp 83 drives the grippers to release the product, completing one insertion action. This cycle repeats, completing the automated testing and insertion process for all products.

Step S6: The receiving clamping mechanism (7) receives the flipped product; Step S7: The feeding insertion device (8) picks up the product from the receiving clamping mechanism (7) and transfers the product to the capacitance test socket (9).
