Description

Technical Field

[0001] This application relates to the technical field of motor manufacturing, and more particularly to a station switching and locking device for dispensing equipment. Background Technology

[0002] With the rapid development of industries such as home appliances and consumer electronics, the market demand for small-power motors, such as brushless motors and shaded-pole motors, has experienced explosive growth. In the assembly process of small motors, the dispensing process is a key step in ensuring the motor's sealing, insulation, and structural stability. This has placed increasingly higher demands on dispensing accuracy, efficiency, and consistency, driving continuous innovation and upgrading of dispensing equipment used in motor production.

[0003] Currently, in the mass production of small motors, dual-head horizontal dispensing machines are widely used due to their features such as simultaneous operation of two dispensing heads and a horizontal layout suitable for horizontal motor installation. Existing dual-head horizontal dispensing machines typically include a rotating frame, a carrier plate mounted on the rotating frame, and a dispensing head assembly capable of moving up, down, left, and right. The operator places the semi-finished motor to be dispensed onto the carrier plate, and then rotates the carrier plate via the rotating frame. Combined with the precise displacement of the dispensing head, the dispensing operation at the designated location on the motor can be completed. To ensure that the dispensing quality meets standards, the dispensing machine is also equipped with a detection camera for real-time monitoring of parameters such as the dispensing trajectory, glue volume, and glue dot shape.

[0004] However, the inspection cameras of existing dual-head horizontal dispensing machines are generally fixed in place, usually close to the carrier tray to ensure the inspection field of view and accuracy. In actual production, operators need to frequently put semi-finished motor products to be dispensed into the carrier tray or remove dispensed motor parts from the carrier tray. During the picking and placing process, collisions with the fixed inspection camera are very likely. As a high-precision optical inspection component, the inspection camera not only has a high procurement cost, but its core components such as the lens are also fragile. Once a collision occurs and it is damaged, it will not only cause the dispensing machine to stop and affect production efficiency, but also generate high equipment maintenance and replacement costs, causing unnecessary economic losses to the enterprise. Summary of the Invention

[0005] This application provides a station switching and locking device for dispensing equipment, which solves the technical problems of existing equipment such as easy camera collision, accidental shutdown, and insufficient dispensing accuracy. By combining an anti-misoperation structure with a gear and rack locking transmission, the device enables station switching on the machine frame, thereby achieving the effects of cost reduction, efficiency improvement, and ensuring dispensing quality and operational safety.

[0006] This application provides a station switching and locking device for a dispensing equipment, including a rotating frame located on a machine base and below a dispensing head assembly. A carrier plate for positioning a motor is mounted on the rotating frame. A camera detection assembly that illuminates the carrier plate is mounted above the machine base. A moving mechanism for laterally moving the rotating frame is mounted on the machine base. The moving mechanism includes a strip box holder fixed to the machine base with an open end facing outwards. A strip-shaped groove is formed on the upper surface of the strip box holder, with one end extending through the open end. A square groove with a width greater than the strip-shaped groove is formed on the upper surface of the strip box holder near the outer side of the machine base. The square groove is located on the bottom edge of one side of the strip box holder along its length and faces away from the machine base. One end of the open end of the carton holder is provided with a smooth guide edge. A right-angle plate is fixed to the bottom edge of the square groove near the open end of the carton holder. One right-angle side of the right-angle plate is parallel to the groove edge of the strip groove and passes through the center line of the strip groove, while the other right-angle side is flush with the bottom edge of the square groove. A movable strip is slidably disposed in the carton holder, with one end extending out of the open end of the carton holder. An adapter is fixed to the movable strip, and the rotating frame is fixed to the adapter. A movable block is rotatably disposed on the movable strip and is used to move within the strip groove. The movable block has triangular slots at both ends, and the right-angle plate is used to engage with the triangular slots. The machine base is also provided with a locking mechanism for locking the movable block.

[0007] Furthermore, the locking mechanism includes: two locking pins, each used to engage with the triangular slots at both ends of the movable block; a support plate, fixed to the machine base and located on one side of the carton seat away from the opening end; two swing rods, rotatably mounted on the support plate, with the two locking pins respectively fixed to the ends of the two swing rods away from the pivot; an opening and closing assembly, mounted on the support plate and used for the openings of the swing rods on both sides; and a telescopic cylinder for driving the operation of the opening and closing assembly.

[0008] Furthermore, the opening and closing assembly includes: a slide rail fixed to the support plate and perpendicular to the strip box seat; a rack slidably connected to the slide rail, with teeth on both sides of the rack, and the telescopic cylinder used to drive the rack to move; two main gears symmetrically rotatably disposed on both sides of the support plate, and the end of the rocker arm away from the locking pin fixedly connected to the main gears; wherein, the rack is used to drive the main gears to rotate.

[0009] Furthermore, the opening and closing assembly also includes intermediate gears. Two intermediate gears are provided and symmetrically rotated on both sides of the support plate. One intermediate gear on one side meshes with the rack and the main gear on the same side.

[0010] Furthermore, with one end of the moving bar abutting the end of the bar holder away from the opening, the center line of the rack passes through the rotation axis of the moving block.

[0011] Furthermore, the upper surface of the movable block is higher than the upper surface of the carton seat, and the lower bottom surface of the locking pin is higher than the upper surface of the carton seat.

[0012] Furthermore, the square groove has an oblique angle at the diagonal point opposite to the right-angle plate, and the oblique angle is connected to the strip groove.

[0013] Furthermore, a limit block is fixed to the upper surface of the end of the movable strip that extends out of the opening of the strip box seat.

[0014] Furthermore, the moving bar moves in the direction of the front of the machine platform.

[0015] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0016] 1. The station switching and locking device for dispensing equipment of this application takes the lateral displacement of the rotating frame driven by the moving mechanism and the precise positioning of the locking mechanism as the core. The lateral displacement structure composed of the strip box seat, the moving strip, etc. realizes the switching of the tray between the pick-up and dispensing station and the dispensing station. When switching to the pick-up and dispensing station, it can move away from the camera detection component 505 to realize the safe pick-up and dispensing of the motor workpiece.

[0017] 2. The square slot, right-angle plate, and triangular slot of the moving block on the strip box base constitute an anti-misoperation structure, which can lock the rotating frame at the pick-up and put-down station, preventing the frame from retracting and colliding with the camera when the pick-up and put-down is not completed. This effectively solves the technical problems of high risk of camera collision, machine stoppage due to misoperation, and insufficient locking accuracy affecting dispensing quality in existing equipment. Ultimately, it achieves the technical effects of significantly reducing camera damage costs, improving production continuity and efficiency, ensuring consistent dispensing accuracy, and enhancing operational convenience and safety.

[0018] 3. The locking mechanism uses a transmission chain of telescopic cylinder, rack, gear and rocker arm to open and close the locking column, which can ensure the locking column firmly locks the moving block, ensure the stability of the rotating frame during dispensing, and reduce the impact of displacement on dispensing accuracy.

Detailed Implementation

[0028] To better understand the technical solution of this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1 A station switching and locking device for dispensing equipment includes a rotating frame 3, a carrier plate 4, a moving mechanism 6, and a locking mechanism 7.

[0030] The dispensing equipment's base 101 possesses excellent stability and load-bearing capacity, providing a solid foundation for the efficient operation of the entire dispensing machine. The moving mechanism 6 is tightly fixed to the surface of the base 101 by multiple high-strength bolts. Two sets of moving mechanisms 6 are symmetrically arranged on the surface of the base 101. A rotating frame 3 is mounted on the moving mechanism 6, allowing the rotating frame 3 to move horizontally upwards in the front direction of the base 101. Each set of moving mechanisms 6 is equipped with a rotating frame 3, and each rotating frame 3 is equipped with a carrier tray 4. The carrier tray 4 is used to position the motor to be dispensed, and the rotating frame 3 allows the carrier tray 4 to rotate. Two sets of dispensing head assemblies 202 are also provided, symmetrically arranged above the base 101. The dispensing head assemblies 202 can move up, down, forward, and backward. By utilizing the movement of the dispensing head assemblies 202 and the rotation of the carrier tray 4 driven by the rotating frame 3, dispensing can be performed on the motor to be dispensed on the carrier tray 4.

[0031] Reference Figure 2 and Figure 3 The moving mechanism 6 includes a carton holder 61, a moving strip 62, an adapter 63, and a moving block 64. The end of the carton holder 61 facing outwards from the machine base 101 is designed as an opening, providing conditions for the subsequent installation and movement of the moving strip 62. The moving strip 62 is slidably disposed inside the carton holder 61. Using a precision track system, the moving strip 62 slides smoothly and accurately within the carton holder 61, and one end can flexibly extend out of the opening end of the carton holder 61. A limit block 621 is fixed to the upper surface of the end of the moving strip 62 extending out of the opening end of the carton holder 61, preventing the moving strip 62 from completely entering the carton holder 61. The upper surface of the carton holder 61 has a strip groove 611, the width of which matches the size of the movable block 64. The movable block 64 is rotatably mounted on the upper surface of the movable strip 62, ensuring that the movable block 64 can move freely within the strip groove 611. Equilateral triangular slots 641 are formed at both ends of the movable block 64, and the upper surface of the movable block 64 is higher than the upper surface of the carton holder 61. An adapter 63 is securely fixed to the movable strip 62 by welding, and the adapter 63 passes through the strip groove 611. The adapter 63 is used to mount the rotating mechanism. Thus, the movement of the movable strip 62 within the carton holder 61 allows the rotating frame 3 to move synchronously.

[0032] Therefore, when the operator pulls the moving bar 62, it can drive the rotating frame 3 to move laterally along the front of the machine table 101, so that the carrier plate 4 can be moved from the dispensing station, that is, close to the dispensing head assembly 202 and the camera detection assembly 505, to the pick-up and put-away station, that is, away from the camera detection assembly 505, so as to achieve safe pick-up and put-away of motor workpieces.

[0033] Furthermore, on the upper surface of the carton holder 61, near the outer side of the machine base 101, a square-width groove 612 with a width greater than the strip groove 611 is provided. The square-width groove 612 is located on the bottom edge of one side of the length direction of the carton holder 61 and has a smooth guide edge 613 at the end facing away from the opening end of the carton holder 61. On the same side of the smooth guide edge 613, a right-angle plate 614 is fixed on the bottom edge of the square-width groove 612 near the opening end of the carton holder 611. One right-angle side of the right-angle plate 614 is parallel to the groove edge of the strip groove 611 and passes through the center line of the strip groove 611, while the other right-angle side is flush with the bottom edge of the square-width groove 612. The design of the right-angle plate 614 allows it to accurately engage with the triangular slot 641 on the moving block 64, thereby enabling the rotation of the moving block 64.

[0034] When it is necessary to move the rotating frame 3 out of the machine base 101, the operator only needs to pull the moving bar 62 outward, causing the moving bar 62 to move outward within the bar holder 61, thereby moving the rotating frame 3 on the adapter 63. This also enables the carrier plate 4 to move laterally out of the machine base 101, allowing the operator to perform the discharge and pick-up operation at a position away from the camera detection component 505. When the moving block 64 moves towards the square slot 612, with the push of the moving bar 62, the moving block 64 gradually approaches the square slot 612. When the moving block 64 enters the square slot 612, the triangular slots 641 at both ends first contact the right-angle plate 614. Due to the special shape and position of the right-angle plate 614, it will exert a lateral force on the triangular slots 641, causing the moving block 64 to rotate around the axis (e.g., Figure 4 (As shown). When the operator is using the power dispensing machine, if they do not carefully push the moving bar 62 into the machine base 101, the special structure of the square-width slot 612 will hinder the movement of the moving block 64. This is because the rotational position of the moving block 64 within the square-width slot 612 prevents it from directly entering the strip slot 611, thus effectively hindering the movement of the moving bar 62 (as shown). Figure 5 As shown in the figure, this can solve the problem of the moving bar 62 sliding into the machine base 101 before the motor is picked up or placed due to operator error.

[0035] Furthermore, refer to Figure 3 and Figure 5 An angled section 615 is provided at the diagonal of the right-angle plate 614 in the square groove 612, and the angled section 615 is connected to the strip groove 611. The angled section 615 causes the moving block 64 to rotate again in the same direction. At this time, after the operator has finished picking up and placing the motor, he pulls the moving bar 62 outward from the machine platform 101. The moving block 64 will contact the right-angle plate 614 again. Due to the action of the angled section 615, the moving block 64 has rotated again. At this time, the right-angle plate 614 will not be locked into the triangular slot 641 of the moving block 64. The right-angle plate 614 will abut against the outer side of the moving block 64, thus causing the moving block 64 to rotate again (e.g., Figure 6 (As shown), then the operator can push the moving bar 62 inwards towards the machine base 101, and the moving block 64 will enter the strip groove 611 under the action of the bevel angle 615 and the smooth guide edge 613 (as shown). Figure 7 As shown), it moves smoothly to the inside of the machine 101, which also moves the carrier 4 with the dispensing motor to the bottom of the dispensing head assembly 202.

[0036] Therefore, the square-width groove 612 and right-angle plate 614 on the carton holder 61 and the triangular groove 641 of the moving block 64 constitute an anti-misoperation structure.

[0037] Reference Figure 2 , Figure 3 and Figure 8 As shown, the locking mechanism 7 includes locking pins 71, a support plate 72, a swing rod 73, an opening and closing assembly 74, and a telescopic cylinder. The support plate 72 is fixed to the machine base 101 and located on one side of the carton holder 61, away from the opening end of the carton holder 61. Two locking pins 71 and two swing rods 73 are provided, symmetrically arranged on both sides of the support plate 72. The locking pins 71 match the triangular slots 641 of the moving block 64, and the two locking pins 71 can tightly engage in the triangular slots 641 at both ends of the moving block 64, thus locking the moving block 64. Two swing rods 73 are provided, rotatably mounted on the support plate 72 via bearings. The two locking pins 71 are respectively fixed to the ends of the two swing rods 73 away from the rotating shaft. When the swing rods 73 rotate, they can drive the locking pins 71 to accurately engage or disengage from the triangular slots 641 of the moving block 64.

[0038] The opening / closing assembly 74 is mounted on the support plate 72. It is the component that enables the two swing arms 73 to swing, and it consists of a slide rail 741, a rack 742, a main gear 743, and an intermediate gear 744. The telescopic cylinder 75 is the power source for the entire locking mechanism 7. It is connected to the opening / closing assembly 74 through a connecting component and provides power support for the operation of the opening / closing assembly 74. The slide rail 741 is perpendicular to the bar box seat 61 and fixed to the support plate 72. The rack 742 is slidably connected to the slide rail 741 through a slider. This connection method allows the rack 742 to move smoothly on the slide rail 741. The piston rod of the telescopic cylinder 75 is connected to the rack 742. When the piston rod of the telescopic cylinder 75 extends or retracts, it drives the rack 742 to move on the slide rail 741. Two main gears 743 are provided, symmetrically rotated on both sides of the support plate 72. The end of the rocker arm 73 away from the locking pin 71 is fixedly connected to the main gear 743. Two intermediate gears 744 are also provided, symmetrically rotated on both sides of the support plate 72. One intermediate gear 744 meshes between the rack 742 and the main gear 743 on the same side. The presence of the intermediate gear 744 can effectively transmit power, making the transmission between the rack 742 and the main gear 743 smoother and more reliable.

[0039] When rack 742 moves, the teeth on both sides mesh with the intermediate gear 744, thereby driving the main gear 743 to rotate. The rotation of the main gear 743 further drives the rocker arm 73 to rotate, realizing the opening and closing action of the locking pin 71. When one end of the moving bar 62 abuts against the end of the strip box seat 61 away from the opening, the center line of rack 742 passes exactly through the rotation axis of moving block 64. This precise positional relationship ensures that when locking moving block 64, locking pin 71 can accurately engage with triangular groove 641, achieving a firm lock on moving block 64, thereby ensuring the stability and accuracy of rotating frame 3 during dispensing.

[0040] The functional principle of this application can be explained through the following methods:

[0041] When the operator pulls the moving bar 62, it can drive the rotating frame 3 to move laterally along the front of the machine table 101, so that the carrier tray 4 moves from the dispensing station, that is, close to the dispensing head assembly 202 and the camera detection assembly 505, to the pick-up and put-away station, that is, away from the camera detection assembly 505, so as to realize the safe pick-up and put-away of the motor workpiece.

[0042] The square slot 612, right-angle plate 614, and triangular slot 641 of the moving block 64 on the strip box holder 61 constitute an anti-misoperation structure. The principle is that when the moving block 64 enters the square slot 612, the right-angle plate 614 engages with the triangular slot 641, forcing the moving block 64 to rotate. If the operator mistakenly pushes the moving strip 62 into the machine base 101, the rotated moving block 64 will abut against the edge of the square slot 612 and cannot enter the strip slot 611, thus locking the rotating frame 3 at the pick-and-place position and preventing the frame from retracting and colliding with the camera before the pick-and-place operation is completed. During reset, the bevel 615 and smooth guide edge 613 guide the moving block 64 to rotate again, allowing it to smoothly slide back into the strip slot 611.

[0043] The locking mechanism 7 achieves the opening and closing of the locking pin 71 through a transmission chain of a telescopic cylinder 75, a rack 742, a gear, and a rocker arm 73. The principle is that the telescopic cylinder 75 drives the rack 742 to move along the slide rail 741. The rack 742 drives the main gear 743 to rotate via the intermediate gear 744. The rocker arm 73, fixedly connected to the main gear 743, swings accordingly, causing the locking pin 71 to precisely engage with the triangular slot 641 of the moving block 64. When the rotating frame 3 returns to the dispensing station, the center line of the rack 742 coincides with the rotation axis of the moving block 64, ensuring a secure lock on the moving block 64 by the locking pin 71. This guarantees the stability of the rotating frame 3 during dispensing and reduces the impact of displacement on dispensing accuracy.

[0044] Therefore, this application uses the moving mechanism 6 to move the carrier tray 4 to a position away from the camera for picking up and placing workpieces, thus spatially isolating the risk of collision. Furthermore, traditional equipment lacks an anti-misoperation structure, and operators may accidentally push the carrier tray backward when picking up or placing workpieces, causing dispensing to start before the operation is completed or colliding with the camera, leading to equipment shutdown. The square slot 612 and right-angle plate 614 of this application, in conjunction, can lock the frame during the picking and placing phase, reducing downtime caused by misoperation. If the rotating frame 3 shifts during dispensing, it can lead to dispensing trajectory deviation and uneven glue application. The locking mechanism 7 of this application uses a gear and rack 742 to achieve precise positioning of the locking pin 71, ensuring the stability of the frame at the dispensing station and guaranteeing dispensing accuracy.

[0045] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.

[0046] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present application, based on the technical solution and concept of the present application, should be covered within the scope of protection of the present application.
