Description

A stator assembly feeding machine Technical Field

[0001] This invention relates to the field of motor processing technology, and specifically to a stator assembly blanking machine. Background Technology

[0002] The stator assembly, as the stationary core component of a motor or generator, is also commonly referred to as the stator system. It mainly consists of the stator core, stator windings, and frame, and is a crucial component for converting electrical energy into mechanical energy. After assembly, the stator assembly undergoes multiple inspection processes, among which visual inspection is a critical step in ensuring product quality and electrical safety. Specifically, visual inspection typically covers the inspection of the core and insulation paper, windings (coils), and solder joints and connections. This includes, but is not limited to: checking for deformation or warping of the core teeth; ensuring the insulation paper is properly installed, undamaged, or misaligned; verifying the neatness, crossover, overlap, or looseness of the enameled wires; and checking the fullness, integrity, and presence of any burn marks, slag spatter, or other defects in the solder joints. Visual inspection allows for the early detection of potential electrical risks caused by physical defects such as damaged enameled wires, residual iron filings, or misaligned insulation paper.

[0003] Currently, the aforementioned appearance inspection process typically employs manual operation, with operators placing stator components one by one under a vision inspection device for testing. This method suffers from significant efficiency bottlenecks. Furthermore, after inspection, operators must separate good and defective products into their respective blister packs based on the results. Prolonged repetitive work can lead to visual fatigue and decreased concentration among operators, resulting in the mixing of good and defective products and affecting product sorting accuracy. In addition, when the blister packs are full, operators must manually move and stack them and replace empty packs, further disrupting the continuity of the inspection process and reducing overall production efficiency.

[0004] It is evident that the existing stator assembly appearance inspection process is inadequate in terms of inspection efficiency, sorting accuracy, and automation of material handling, and urgently needs improvement. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a stator assembly feeding machine that can automatically separate good and defective products, avoid mixing, and automatically stack full-load blister trays to improve the efficiency of inspection and feeding.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A stator assembly blanking machine includes a machine base, and the blanking machine further includes:

[0008] Conveying component one, which is mounted on the machine base;

[0009] A tray, which is mounted on a conveying assembly and on which a stator assembly to be tested is placed;

[0010] A through-beam detector, which is mounted on the machine base and used to detect whether the tray has reached the detection position;

[0011] A feeding platform is installed on one side of the machine, and a blister tray for loading qualified stator components is placed on the feeding platform;

[0012] A handling and inspection mechanism, which is installed on the unloading platform, is used to inspect the appearance of the stator assembly;

[0013] The sorting component is installed on the machine platform and is used to determine whether the appearance of the stator component is qualified. After making the judgment, the handling and detection mechanism is controlled by digital signals to transport the qualified stator component into the blister tray, and the conveying component is controlled to transport the unqualified stator component to the next process through the tray.

[0014] As a further aspect of the present invention: the handling and inspection mechanism includes a robotic arm and a CCD inspection component, wherein the robotic arm is provided with a clamp for holding the stator assembly, and the CCD inspection component includes an inspection camera and a supplementary light.

[0015] As a further aspect of the present invention: the unloading platform is provided with a through hole one and a through hole two, a plurality of empty blister trays are stacked in the through hole one, and a plurality of blister trays containing qualified stator assemblies are stacked in the through hole two. Except for the uppermost blister tray, all the lower blister trays are filled with qualified stator assemblies. A transverse mechanism is installed on the unloading platform. The transverse mechanism is used to transfer the blister trays so that the empty blister trays are moved from the through hole one to the through hole two.

[0016] As a further embodiment of the present invention: the transverse mechanism includes a movable frame, a guide rail and a locking member. The movable frame is driven and mounted on the guide rail. The blister tray for loading qualified stator assemblies is located on the movable frame. The locking member is mounted on the movable frame and is used to fix the blister tray located on the movable frame.

[0017] As a further embodiment of the present invention: the unloading platform is equipped with a lifting mechanism and a lowering mechanism respectively. The lifting mechanism is located at one through hole and drives several empty blister trays to move upward. The lowering mechanism is located at another through hole and drives several blister trays equipped with qualified stator assemblies to move downward. An adsorption mechanism is installed on the unloading platform and is used to adsorb the uppermost empty blister tray.

[0018] As a further aspect of the present invention: a connecting cover is provided on one side of the unloading platform, the connecting cover is connected to the inside of the unloading platform, and two sets of conveying components are installed in the connecting cover and the unloading platform. The two sets of conveying components correspond to an empty blister tray and a blister tray filled with qualified stator components, respectively. One set of conveying components transports the empty blister tray to the lifting mechanism, and the other set of conveying components transports several blister trays filled with qualified stator components from the lowering mechanism.

[0019] As a further aspect of the present invention: the input and output ends of the two sets of conveying components are respectively provided with turnover cart one and turnover cart two.

[0020] As a further aspect of the present invention: a positioning component is installed inside the machine tool, the positioning component is located at one point of the conveying assembly, and the positioning component is used to fix the pallet that has stopped moving.

[0021] The beneficial effects of this invention are:

[0022] (1) By setting up a conveying component, a tray, a through-beam detector and a handling and inspection mechanism, the stator component to be inspected is automatically conveyed to the inspection position by the conveying component. After the through-beam detector triggers the positioning, the handling and inspection mechanism automatically completes the appearance inspection, which replaces the traditional manual method of placing and inspecting one by one, and significantly improves the inspection efficiency.

[0023] (2) By setting up a sorting component and a handling and inspection mechanism to work together, the sorting component automatically judges good products and defective products according to the inspection results, and controls the handling and inspection mechanism to transfer good products to the blister tray and controls the conveying component to transport defective products to the next process. This realizes the automatic sorting and isolation of good products and defective products, avoids the problem of mixing materials due to visual fatigue or decreased attention during manual sorting, and ensures the accuracy of product sorting.

[0024] (3) By setting through hole one, through hole two, lifting mechanism, lowering mechanism, lateral movement mechanism and adsorption mechanism on the unloading platform, the present invention realizes the automatic replenishment of empty blister trays, the automatic stacking and replacement of full-load blister trays, and the automatic input and output of blister trays through the cooperation of conveying component two and turnover cart, effectively connecting the detection cycle, avoiding the process interruption caused by manual handling, stacking and replacement of blister trays, ensuring the continuity of the detection process, and further improving the overall production efficiency.

[0034] 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.

[0035] As shown in Figures 1-6, a stator assembly blanking machine includes a machine base 1, and the blanking machine further includes:

[0036] Conveying component 2 is installed on machine base 1;

[0037] Pallet 3 is mounted on conveyor assembly 2, and the stator assembly to be tested is placed on pallet 3;

[0038] Through-beam detector 4 is installed on machine base 1 and is used to detect whether tray 3 has reached the detection position;

[0039] The unloading platform 6 is installed on one side of the machine base 1. The unloading platform 6 has a blister tray for loading qualified stator components.

[0040] The handling and inspection mechanism 5 is installed on the unloading platform 6 and is used to inspect the appearance of the stator assembly.

[0041] The sorting component 11 is installed on the machine 1 and is used to determine whether the appearance of the stator component is qualified. After making the judgment, the handling and inspection mechanism 5 is controlled by digital signal to transport the qualified stator component to the blister tray, and the conveying component 2 is controlled to transport the unqualified stator component to the next process through the tray 3.

[0042] In one embodiment, the sorting component 11 is connected to the handling and inspection mechanism 5. The images detected by the handling and inspection mechanism 5 are transmitted to the sorting component 11. After analysis, the sorting component 11 obtains NG or OK results, that is, it determines whether the product is defective or good. The laser beam detector 4 emits a laser.

[0043] In practical application, the stator assembly to be tested is placed on tray 3, which is conveyed by conveyor assembly 2. When tray 3 moves to the through-beam detector 4, the laser emitted by the through-beam detector 4 is blocked by tray 3 and the stator assembly to be tested. At this time, the through-beam detector 4 sends a signal to the external control unit, which then controls conveyor assembly 2 to stop, thus placing the stator assembly in the test position. At this time, the handling and testing mechanism 5 will inspect the appearance of the stator assembly. The image generated during the inspection will be transmitted to the sorting assembly 11. After passing through the sorting assembly 11, NG and OK results are obtained. When the stator assembly is OK, the handling and testing mechanism 5 will transfer the qualified stator assembly to the blister tray, thus completing the unloading. When the stator assembly is NG, the external control unit controls conveyor assembly 2 to start, thereby transferring the unqualified stator assembly to the next process via tray 3. This not only improves testing efficiency, but also allows qualified stator components to be loaded into blister trays via the handling and testing mechanism 5, while unqualified stator components are moved to the next process, thus avoiding confusion between good and bad products during material handling and ensuring the accuracy of product sorting.

[0044] Furthermore, a positioning element 16 is installed inside the machine 1. The positioning element 16 is located at the conveying assembly 2 and is used to fix the stopped pallet 3.

[0045] In practical application, when the tray 3 moves to the through-beam detection component 4, the tray 3 stops moving. At this time, the positioning component 16 will fix the tray 3, thereby making the tray 3 and the stator component to be tested stable, thus ensuring the accuracy of the test results.

[0046] Furthermore, the handling and inspection mechanism 5 includes a robotic arm 51 and a CCD inspection component 52, wherein the robotic arm 51 is equipped with a clamp for holding the stator assembly, and the CCD inspection component 52 includes an inspection camera and a supplementary light.

[0047] In practical application, during inspection, the stator assembly is photographed by a detection camera, and the image quality is improved by a supplementary light. The image is then transmitted to the sorting assembly 11, which analyzes whether there are any defects in the stator assembly in the image and provides a result indicating whether it is qualified. When the stator assembly is qualified, the control unit controls the robotic arm 51 to approach the stator assembly and clamp the stator assembly with a fixture, and then transfers the stator assembly into a blister tray.

[0048] Furthermore, the unloading platform 6 is provided with through holes 61 and 62 respectively. Several empty blister trays are stacked in through hole 61, and several blister trays containing qualified stator components are stacked in through hole 62. Except for the topmost blister tray, all the lower blister trays are filled with qualified stator components. The unloading platform 6 is equipped with a transverse mechanism 7, which is used to transfer the blister trays so that the empty blister trays are moved from through hole 61 to through hole 62.

[0049] The transverse mechanism 7 includes a movable frame 71, a guide rail, and a locking element 72. The movable frame 71 is driven and mounted on the guide rail. The blister tray for loading qualified stator assemblies is located on the movable frame 71. The locking element 72 is mounted on the movable frame 71 and is used to fix the blister tray located on the movable frame 71.

[0050] The unloading platform 6 is equipped with an lifting mechanism 9 and a lowering mechanism 10. The lifting mechanism 9 is located at the first through hole 61 and drives several empty blister trays to move upward. The lowering mechanism 10 is located at the second through hole 62 and drives several blister trays equipped with qualified stator assemblies to move downward. The unloading platform 6 is equipped with an adsorption mechanism 8, which is used to adsorb the uppermost empty blister tray.

[0051] In practical application, when the blister tray at through-hole 62 is full of stator assemblies, the locking member 72 releases its fixation. At this point, the lowering mechanism 10 moves the uppermost blister tray downwards, while the suction mechanism 8 holds it and moves it upwards. Then, the moving frame 71 moves along the guide rail towards through-hole 61. The suction mechanism 8 moves the blister tray downwards into the moving frame 71, which then moves along the guide rail towards through-hole 62. Finally, the locking member 72 locks it in place, and the rising mechanism 9 moves the empty blister tray upwards. This completes the replacement of the empty blister tray, and the blister trays containing stator assemblies are automatically stacked, ensuring the continuity of the inspection process and improving overall production efficiency.

[0052] Furthermore, a connecting cover 12 is provided on one side of the unloading platform 6. The connecting cover 12 is connected to the inside of the unloading platform 6. Two sets of conveying components 13 are installed in the connecting cover 12 and the unloading platform 6. The two sets of conveying components 13 correspond to the empty blister tray and the blister tray filled with qualified stator components, respectively. One set of conveying components 13 transports the empty blister tray to the lifting mechanism 9, and the other set of conveying components 13 transfers several blister trays filled with qualified stator components from the lowering mechanism 10.

[0053] The input and output ends of the two sets of conveying components 13 are respectively equipped with turnover cart 14 and turnover cart 2 15.

[0054] In practical application, the first turnover cart 14 transfers several stacked empty blister trays to the second conveyor assembly 13. The second conveyor assembly 13 then transfers the stacked empty blister trays to the lifting mechanism 9. The lifting mechanism 9 then moves the empty blister trays upwards, thus retrieving the prepared empty blister trays for subsequent unloading. When the stacked blister trays at the lowering mechanism 10 are all filled with stator components, the second conveyor assembly 13 on the other side transfers the stacked full-load blister trays to the second turnover cart 15. The second turnover cart 15 then transfers the qualified stator components to the next process step. This automates the stacking and replacement of blister trays, ensuring accurate unloading and further ensuring the continuity of the inspection process.

[0055] Working principle: During operation, the stator assembly to be tested is first placed on the tray 3. The conveying assembly 2 is started and the tray 3 is conveyed along the machine table 1. When the tray 3 moves to the through-beam detector 4, the laser emitted by the through-beam detector 4 is blocked by the tray 3 and the stator assembly. At this time, the through-beam detector 4 sends a signal to the external control unit. The control unit controls the conveying assembly 2 to stop and starts the positioning component 16 to fix the tray 3 in the detection position. Then, the CCD detector 52 in the handling and detection mechanism 5 is started. The detector camera takes pictures of the stator assembly with the help of the supplementary light and transmits the images to the sorting assembly 11. The sorting assembly 11 analyzes and judges the images to obtain a qualified or unqualified result. If the result is qualified, the sorting assembly 11 sends a digital signal to control the robotic arm 51 to pick up the stator assembly with the clamp and transfer it to the blister tray located in the moving frame 71 on the unloading table 6. If the result is unqualified, the sorting assembly 11 controls the conveying assembly 2 to restart and transport the unqualified stator assembly to the next process through the tray 3.

[0056] When the blister tray on the moving frame 71 is filled with qualified stator assemblies, the locking member 72 releases the blister tray, the lowering mechanism 10 is activated, and the fully loaded blister tray is moved downward into the through hole 62 for stacking. At the same time, the adsorption mechanism 8 adsorbs the top empty blister tray at the through hole 61 and lifts it upward. The moving frame 71 in the transverse mechanism 7 moves along the guide rail to above the through hole 61, the adsorption mechanism 8 lowers the empty blister tray into the moving frame 71, the moving frame 71 then returns to the through hole 62, the locking member 72 re-fixes the empty blister tray, and the rising mechanism 9 pushes the remaining stacked empty blister trays upward to the position to be retrieved. Empty blister trays are transferred to one of the conveying components 13 via a turnover cart 14, and then conveyed to the lifting mechanism 9 for replenishment. When the number of fully loaded blister trays stacked at the lowering mechanism 10 reaches the set number, another conveying component 13 transfers them to a turnover cart 15 and sends them to the next process, realizing the automated circulation of blister trays.
