[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] The following is for reference. Figures 1-5 This invention describes an automatic dispensing machine according to an embodiment of the present invention.

[0023] like Figures 1-5 As shown, the automatic dispensing machine includes a frame 1, on which a protective cover 2 is installed to prevent external personnel from accidentally touching the processing area. It also includes an X-axis moving mechanism, a dispensing mechanism, a Y-axis moving mechanism, a switching plate mechanism, and a fixture lifting mechanism.

[0024] The bottom of frame 1 contacts the placement surface, and the top is a horizontal platform. An X-axis moving mechanism is mounted on the top platform of frame 1 and reciprocates horizontally along the length of frame 1. A dispensing mechanism is mounted on the X-axis moving mechanism and moves with it along the length of frame 1. A Y-axis moving mechanism is located between the top platform of frame 1 and the X-axis moving mechanism and reciprocates horizontally along the width of frame 1. A switching plate mechanism is mounted on the Y-axis moving mechanism and moves with it along the width of frame 1. A fixture lifting mechanism is located within frame 1 and exposed on the top platform of frame 1.

[0025] The dispensing mechanism includes a first dispensing assembly 41 and a second dispensing assembly 42, which are respectively disposed at both ends of the frame 1 along its length. The first dispensing assembly 41 and the second dispensing assembly 42 are either close to or far from each other along the length of the frame 1. The switching plate mechanism includes an upper switching assembly 61 and a lower switching assembly 62, which are spaced apart along the height of the frame 1.

[0026] Along the height direction of the frame 1, when the orthographic projection of the jig lifting mechanism overlaps with the orthographic projection of the upper switching component 61, the orthographic projection of the lower switching component 62 does not overlap with the orthographic projection of the jig lifting mechanism.

[0027] Alternatively, when the orthographic projection of the jig lifting mechanism overlaps with the orthographic projection of the lower switching component 62, the orthographic projection of the upper switching component 61 does not overlap with the orthographic projection of the jig lifting mechanism.

[0028] The frame 1 of the automatic dispensing machine adopts a heavy-duty welded frame structure. The bottom is stably in contact with the workshop floor via adjustable feet, and the top is covered with a high-precision platform as an assembly reference surface. The X-axis moving mechanism is mounted above the platform and consists of two parallel linear guide rails extending along the length of frame 1 to both ends, driving the dispensing mechanism to achieve horizontal reciprocating movement. The Y-axis moving mechanism is embedded below the platform, arranged along the width of frame 1, and adopts a layered, three-dimensional design to save space. The switching plate mechanism is mounted on the slider of the Y-axis moving mechanism, achieving station switching as the Y-axis moves forward and backward.

[0029] During operation, the spacing between the first dispensing assembly 41 and the second dispensing assembly 42 can be adjusted independently, and the entire process is completed automatically without manual intervention. The upper switching assembly 61 and the lower switching assembly 62 of the switching plate mechanism are arranged vertically in a staggered manner, forming a double-layer alternating working mode. When the lifting mechanism rises, the upper switching assembly 61 sends the fixture seat 601 into the dispensing station, at which time the lower switching assembly 62 automatically moves to the outer loading and unloading area; when the lifting mechanism descends and resets, the upper switching assembly 61 exits, and the lower switching assembly 62 simultaneously enters the dispensing station. This ensures that there is no spatial interference between the mechanisms during the switching cycle, achieving continuous and uninterrupted production.

[0030] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the X-axis moving mechanism includes a first transverse moving mechanism 31 and a second transverse moving mechanism 32. The first transverse moving mechanism 31 and the second transverse moving mechanism 32 are respectively located at both ends of the frame 1 along its length. The first transverse moving mechanism 31 is connected to the first dispensing assembly 41, and the second transverse moving mechanism 32 is connected to the second dispensing assembly 42. The first transverse moving mechanism 31 and the second transverse moving mechanism 32 respectively drive the first dispensing assembly 41 and the second dispensing assembly 42 to move closer to or further away from each other.

[0031] The X-axis moving mechanism consists of two independent transverse moving mechanisms, located at opposite ends of the frame 1 along its length. The first transverse moving mechanism 31 drives the first dispensing assembly 41, and the second transverse moving mechanism 32 drives the second dispensing assembly 42. The two mechanisms can operate synchronously in the same direction or move in opposite directions relative to each other to adjust the spacing. In actual production, when switching between different product models, the control system automatically calculates the target spacing between the two dispensing assemblies based on preset parameters and drives each transverse moving mechanism to move independently. This eliminates the cumbersome operation of replacing mounting brackets in traditional equipment, significantly improving equipment compatibility.

[0032] In some embodiments of this utility model, such as Figures 1-3 As shown, the Y-axis moving mechanism includes a first forward / backward mechanism 51 and a second forward / backward mechanism 52. The second forward / backward mechanism 52 is located inside the frame 1, and the first forward / backward mechanism 51 is located outside the frame 1. The second forward / backward mechanism 52 is connected to the lower switching component 62, and the first forward / backward mechanism 51 is connected to the upper switching component 61. Along the width direction of the frame 1, the first forward / backward mechanism 51 drives the upper switching component 61 to move closer to or away from the fixture lifting mechanism, and the second forward / backward mechanism 52 drives the lower switching component 62 to move closer to or away from the fixture lifting mechanism.

[0033] The Y-axis moving mechanism adopts an inner and outer layered arrangement. The first forward / backward mechanism 51 is located on the outer side of the frame 1, driving the upper switching component 61 to carry the fixture to be processed into the dispensing area; the second forward / backward mechanism 52 is located on the inner side of the frame 1, driving the lower switching component 62 to carry the processed fixture out of the dispensing area. The two mechanisms reciprocate independently along the width direction without interfering with each other. During operation, when the upper switching component 61 advances to the dispensing position, the lower switching component 62 can simultaneously retreat to the upper or lower material position. The operator can safely pick up and put away finished and semi-finished products during equipment operation, and the human-machine operation cycle completely overlaps, eliminating waiting waste.

[0034] In some embodiments of this utility model, such as Figures 1-3 As shown, the first forward / reverse mechanism 51 and the second forward / reverse mechanism 52 are driven independently. The first forward / reverse mechanism 51 and the second forward / reverse mechanism 52 are independently driven by the control system, enabling asynchronous operation. When the upper switching component 61 is carrying the workpiece for processing at the dispensing station, the lower switching component 62 has already retreated to the outside, allowing manual unloading and loading. After dispensing is completed, the lifting mechanism descends, the upper switching component 61 immediately retracts, and the lower switching component 62 simultaneously advances, significantly shortening the equipment cycle time.

[0035] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, along the height direction of the frame 1, the fixture lifting mechanism, the lower switching component 62, and the upper switching component 61 are arranged sequentially at intervals. The fixture lifting mechanism is located at the bottom, the lower switching component 62 is in the middle, and the upper switching component 61 is on top, with the three layers arranged sequentially at intervals. When fully retracted, the lifting platform 71 of the lifting mechanism is flush with the surface of the frame 1 platform and does not affect the movement of the switching plate mechanism; during operation, the lifting platform 71 is raised upwards, lifting the fixture seat 601 of the upper switching component 61 to the dispensing height. Sufficient dynamic clearances are maintained between the components to eliminate the risk of collision.

[0036] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the upper switching assembly 61 includes a jig base 601 and an upper jig frame 602. The upper jig frame 602 is connected to the first forward / backward mechanism 51, and the jig base 601 is detachably mounted on top of the upper jig frame 602. The lower switching assembly 62 includes a jig base 601 and a lower jig frame 603. The lower jig frame 603 is connected to the second forward / backward mechanism 52, and the jig base 601 is detachably mounted on top of the lower jig frame 603.

[0037] The upper switching assembly 61 consists of a fixture base 601 and an upper fixture frame 602. The upper fixture frame 602 is rigidly connected to the first forward / backward mechanism 51, and a positioning pin is machined on its top. Positioning holes are machined at corresponding positions on the bottom of the fixture base 601, allowing for quick mounting onto the top of the upper fixture frame 602. The lower switching assembly 62 has the same structure, with the fixture base 601 and lower fixture frame 603 using the same positioning method. In actual production, only the corresponding fixture base 601 and fixture plate 604 need to be replaced for different products; the main frame does not need adjustment, making the changeover operation convenient and reliable.

[0038] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the jig base 601 has multiple quick-release components 605 around its periphery, and a detachable jig plate 604 is provided on the surface of the jig base 601. The quick-release components 605 are used to lock the periphery of the jig plate 604. Multiple quick-release components 605 are evenly installed around the periphery of the jig base 601. After the jig plate 604 is placed on the surface of the jig base 601, it can be quickly locked by moving the quick-release components.

[0039] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the jig lifting mechanism includes a lifting seat 72 fixed on the frame 1. A lifting platform 71 is provided above the lifting seat 72 along the height direction of the frame 1. The lifting platform 71 reciprocates along the height direction of the frame 1. The lifting platform 71 is used to lift the jig seat 601 to approach or move away from the dispensing mechanism. Multiple guide rods 76 are provided on the top of the lifting platform 71. The guide rods 76 are sleeved with the lifting seat 72 and extend along the thickness direction of the lifting seat 72.

[0040] The lifting seat 72 is rigidly fixed inside the frame 1, providing a supporting foundation for the overall structure. The lifting platform 71 is located directly above the lifting seat 72 and lifts the fixture through vertical reciprocating motion. Multiple guide rods 76 are installed at the bottom of the lifting platform 71, and the guide rods 76 are inserted into the guide sleeves of the lifting seat 72 to guide the lifting direction throughout the process. During operation, after the lifting drive mechanism 78 is activated, the transmission rod 75 pushes the lifting platform 71 to rise steadily. The precise cooperation between the guide rods 76 and the guide sleeves ensures that the fixture does not deviate during the lifting process, and the repeatability accuracy meets the requirements of high-precision dispensing.

[0041] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the jig lifting mechanism includes a lifting drive mechanism 78, a transmission belt 74, a rotating nut 73, and a transmission rod 75.

[0042] A rotating nut 73 is mounted on a lifting seat 72. A lifting drive mechanism 78 is fixed inside the frame 1, and the output shaft of the lifting drive mechanism 78 is connected to the rotating nut 73 via a transmission belt 74. A transmission rod 75 is connected to the rotating nut 73, and one end is connected to the lifting platform 71. The transmission rod 75 and the guide rod 76 are arranged parallel to each other along the height direction of the frame 1.

[0043] The lifting drive mechanism 78 drives the rotating nut 73 to rotate via the transmission belt 74, which in turn drives the transmission rod 75 to extend and retract linearly. The lifting drive mechanism 78 is fixed to the bottom of the frame 1, and its output shaft is horizontally arranged, transmitting power to the rotating nut 73 via a synchronous belt. The rotating nut 73 and the transmission rod 75 form a screw drive pair, converting rotational motion into the vertical lifting and lowering of the lifting platform 71. This transmission chain design is compact and occupies little space. In particular, when the equipment is powered off or stopped in an emergency, the self-locking characteristic of the rotating nut 73 and the transmission rod 75 can immediately lock the position of the lifting platform 71, preventing damage to the fixture due to gravity and significantly improving equipment safety.

[0044] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the jig lifting mechanism includes a positioning identification part 77, which is disposed in the lifting seat 72 and electrically connected to the lifting drive mechanism 78. When the lifting platform 71 descends to the position of the positioning identification part 77, the lifting drive mechanism 78 stops operating.

[0045] The positioning identification unit 77 is installed inside the lifting base 72 to detect whether the lifting platform 71 has accurately descended to the safe position. The working logic is as follows: during the descent of the lifting platform 71, the positioning identification unit 77 continuously monitors the position signal; when the lifting platform 71 descends to the preset safe point, the identification unit triggers a signal and immediately sends it to the control system, which then stops the lifting drive mechanism 78 and locks the output, significantly improving the reliability of equipment operation.
