Description

Technical Field

[0001] This utility model is a dispensing machine with automatic loading and unloading functions. Background Technology

[0002] Dispensing technology is widely used in electronics manufacturing, LED packaging, automotive parts, medical devices and other fields to achieve sealing, bonding or filling of target workpieces. With the continuous improvement of industrial automation, traditional manual dispensing methods can no longer meet the needs of high efficiency, high precision and mass production. Therefore, automatic dispensing equipment has gradually become the mainstream application.

[0003] In automated dispensing equipment, the material loading and unloading processes are crucial to ensuring the continuity and efficiency of the entire production process. However, in existing technologies, most dispensing equipment still suffers from the following problems in the design of their loading and unloading structures:

[0004] Firstly, the loading and unloading process still relies on manual intervention or semi-automatic operation. If it is necessary to manually place the parts to be processed onto the processing platform one by one or manually transport the processed products, not only is the labor intensity high, but it is also easy to cause workpiece misalignment, scratches or contamination of the glue application area, which seriously affects the processing efficiency and product yield.

[0005] Secondly, existing automatic loading and unloading devices are complex in structure or lack versatility. Some devices use robotic arms, multi-axis servos, or robots to load and unload materials, but these systems are costly, complex to control, and often require significant adjustments to the equipment structure or reprogramming when changing workpiece size or shape, resulting in poor flexibility.

[0006] Third, inaccurate control of material stacking methods can easily lead to problems such as material blockage or pallet slippage. Traditional stacking methods often use pads, partitions, or fixed frames for simple positioning, lacking sophisticated control methods with corresponding limits, making it difficult to ensure the stability of the stacked structure during lifting or handling.

[0007] Therefore, designing an automatic loading and unloading mechanism that is structurally sound, stable in operation, cost-effective, and adaptable to various workpiece forms has become one of the key technical bottlenecks in improving the overall performance and automation level of dispensing equipment. Utility Model Content:

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dispensing machine with automatic loading and unloading functions.

[0009] A dispensing machine with automatic loading and unloading functions includes a loading mechanism, an unloading mechanism, a dispensing mechanism, and a transfer mechanism. The loading mechanism, unloading mechanism, and dispensing mechanism are arranged in a straight line on a table. The dispensing mechanism is located between the loading mechanism and the unloading mechanism. The transfer mechanism is used to sequentially send the parts to be processed from the loading station to the processing station and the unloading station. The loading station, processing station, and unloading station are all located above the transfer mechanism.

[0010] Furthermore, the loading mechanism includes an open shelf, a limiting mechanism, and a lifting mechanism. The workpieces to be processed are stacked in the shelf, and the transfer mechanism is located below the stacked workpieces. The limiting mechanism is used to restrict the vertical movement of the workpieces, and the lifting mechanism is used to drive the workpieces to move vertically.

[0011] Furthermore, the limiting mechanism includes multiple limiting cylinders, which are installed on the side of the shelf at a height close to the transfer mechanism. The extension and retraction direction of the limiting cylinders is perpendicular to the direction of movement of the workpiece. The lifting mechanism includes at least one lifting cylinder, which is installed on the platform and located below the stacked workpieces. The extension and retraction direction of the lifting cylinder is the same as the direction of movement of the workpiece.

[0012] Furthermore, the unloading mechanism has the same structure as the loading mechanism.

[0013] Furthermore, the transplanting mechanism includes two belt transmission structures arranged at relative intervals, and the drive wheels of the two belt transmission structures are linked by a rotating shaft.

[0014] Furthermore, the dispensing mechanism includes a displacement mechanism and a dispensing gun. The displacement mechanism includes an X-axis displacement mechanism, a Y-axis displacement mechanism, and a Z-axis displacement mechanism. The X-axis displacement mechanism is mounted on the Y-axis displacement mechanism, the Z-axis displacement mechanism is mounted on the X-axis displacement mechanism, and the dispensing gun is mounted on the Z-axis displacement mechanism.

[0015] Furthermore, the Y-axis displacement mechanism includes two synchronous belt slide structures arranged in parallel and spaced apart. The X-axis displacement mechanism and the Z-axis displacement mechanism each include a synchronous belt slide structure. The synchronous slide structure of the X-axis displacement mechanism is arranged across the two synchronous slide structures of the Y-axis displacement mechanism. The synchronous slide structure includes a slide, a synchronous belt, a motor, a pulley, and a guide rail. The slide and the guide rail are slidably engaged. Both ends of the synchronous belt are respectively engaged with a pulley. The output end of the motor is connected to one of the pulleys. The synchronous belt is fixedly connected to the slide.

[0016] Furthermore, an industrial camera is also installed next to the dispensing gun.

[0017] Furthermore, the workpiece to be processed is placed in a tray, and multiple trays are stacked in a shelf. The tray is provided with multiple slots for embedding the end of the limit cylinder telescopic rod.

[0018] Beneficial effects: Compared with existing technologies, this dispensing machine integrates a feeding mechanism, a dispensing mechanism, a unloading mechanism, and a transfer mechanism, achieving fully automated operation of the entire process from material feeding to material dispensing. This system can continuously complete dispensing processes without manual intervention, significantly improving production efficiency. It is particularly suitable for industrial scenarios with high requirements for consistency and efficiency, such as electronics manufacturing and precision component packaging.

[0019] The system adopts a modular design, with the loading and unloading mechanisms being structurally identical, making the equipment more unified and simpler in design, manufacturing, assembly, and subsequent maintenance. This symmetrical structure facilitates standardized management and improves equipment versatility, helping to reduce spare parts inventory and maintenance costs.

[0020] During operation, the lifting cylinder and the limiting cylinder work together to achieve layer-by-layer transport and stable control of the pallet. The limiting cylinder can be used with slots on the pallet to effectively prevent the pallet from slipping or becoming misaligned, ensuring stability and safety during dynamic operations such as lifting and lowering. The transplanting mechanism adopts a linked belt structure, ensuring the synchronization and positional accuracy of the pallet during transport, which helps to improve the overall dispensing accuracy and stability.

[0021] The dispensing mechanism possesses X, Y, and Z-axis motion capabilities, forming a high-degree-of-freedom, high-precision working platform in conjunction with an industrial camera. It can flexibly adjust the dispensing trajectory according to the different structural features and process requirements of the product. Simultaneously, the industrial camera provides visual recognition and correction functions, helping to monitor processing quality in real time and automatically correct deviations, further improving finished product consistency and yield.

[0022] In addition, this dispensing machine has a compact overall structure with all mechanisms arranged in a straight line, which saves production space and is suitable for workshop environments with limited space. It also facilitates on-site wiring, control logic planning and maintenance operations, and enhances the system integration and ease of use of the equipment. Attached Figure Description

[0029] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0030] A dispensing machine with automatic loading and unloading functions includes a loading mechanism 1, an unloading mechanism 3, a dispensing mechanism 2, and a transfer mechanism 4. The loading mechanism 1, the unloading mechanism 3, and the dispensing mechanism 2 are arranged in a straight line on a table. The dispensing mechanism 2 is located between the loading mechanism 1 and the unloading mechanism 3. The transfer mechanism 4 is configured to sequentially send the workpiece to be processed from the loading station to the processing station and the unloading station. The loading station, the processing station, and the unloading station are all located above the transfer mechanism 4.

[0031] This dispensing machine uses a linearly arranged feeding mechanism 1, dispensing mechanism 2, and unloading mechanism 3 to form its basic working path. The feeding mechanism 1 positions and feeds the workpiece to be processed, the transfer mechanism 4 moves the workpiece, the dispensing mechanism 2 performs the dispensing operation on the workpiece upon arrival at the processing station, and then the transfer mechanism 4 transfers the processed workpiece to the unloading mechanism 3 for unloading. The transfer mechanism 4 covers the entire path from feeding to processing and then to unloading, ensuring a continuous and efficient automated process. Throughout the process, each station is fixed above the transmission path of the transfer mechanism 4, thus achieving a multi-station integrated layout.

[0032] In one possible implementation, the feeding mechanism 1 includes an open shelf 9, a limiting mechanism, and a lifting mechanism. The workpieces to be processed are stacked in the shelf 9. The transfer mechanism 4 is located below the stacked workpieces. The limiting mechanism is used to restrict the vertical movement of the workpieces to be processed, and the lifting mechanism is used to drive the workpieces to be processed to move vertically.

[0033] In one possible implementation, the limiting mechanism includes multiple limiting cylinders 8, which are mounted on the side of the shelf 9 at a height close to the transfer mechanism 4. The extension and retraction direction of the limiting cylinders 8 is perpendicular to the direction of movement of the workpiece. The lifting mechanism includes at least one lifting cylinder, which is mounted on the platform and located below the stacked workpieces. The extension and retraction direction of the lifting cylinder is the same as the direction of movement of the workpieces.

[0034] In one possible implementation, the unloading mechanism 3 has the same structure as the loading mechanism 1.

[0035] In one possible implementation, the transplanting mechanism 4 includes two belt transmission structures 5 arranged at relative intervals, and the drive wheels of the two belt transmission structures 5 are linked by a rotating shaft 6.

[0036] In this embodiment, the transplanting mechanism 4 consists of belt structures symmetrically arranged on both sides. The drive wheel is driven by a common rotating shaft 6, ensuring synchronous operation on both sides. The workpiece to be processed is conveyed by the belt to the processing station, unloading station, or loading station. The linkage mechanism of the rotating shaft 6 ensures conveying stability and symmetrical clamping, improving positioning accuracy.

[0037] In one possible implementation, the dispensing mechanism 2 includes a displacement mechanism and a dispensing gun 13. The displacement mechanism includes an X-axis displacement mechanism 10, a Y-axis displacement mechanism 11, and a Z-axis displacement mechanism 12. The X-axis displacement mechanism 10 is mounted on the Y-axis displacement mechanism 11, the Z-axis displacement mechanism 12 is mounted on the X-axis displacement mechanism 10, and the dispensing gun 13 is mounted on the Z-axis displacement mechanism 12.

[0038] In one possible implementation, the Y-axis displacement mechanism 11 includes two synchronous belt slide structures arranged in parallel and spaced apart. The X-axis displacement mechanism 10 and the Z-axis displacement mechanism 12 each include a synchronous belt slide structure. The synchronous slide 18 structure of the X-axis displacement mechanism 10 is arranged across the two synchronous slide 18 structures of the Y-axis displacement mechanism 11. The synchronous slide 18 structure includes a slide 18, a synchronous belt 17, a motor 15, a pulley 16, and a guide rail 19. The slide 18 and the guide rail 19 are slidably engaged. Both ends of the synchronous belt 17 are respectively engaged with a pulley 16. The output end of the motor 15 is connected to one of the pulleys 16. The synchronous belt 17 is fixedly connected to the slide 18.

[0039] The use of a synchronous belt 17, guide rail 19, and slide table 18 improves displacement speed and accuracy. The structure is compact, easy to maintain, and suitable for high-cycle, high-stability dispensing scenarios.

[0040] In one possible implementation, an industrial camera 14 is also provided next to the glue gun 13.

[0041] In this embodiment, the industrial camera 14 is positioned near the dispensing gun 13 to acquire images of the dispensing area, enabling visual control functions such as pre-positioning, defect identification, and glue volume monitoring. The system can adjust the dispensing trajectory or process parameters based on the image data, thereby improving the level of automation control.

[0042] In one possible implementation, the workpiece to be processed is placed in a tray 7, and multiple trays 7 are stacked in a shelf 9. The tray 7 is provided with multiple slots for embedding the end of the telescopic rod of the limiting cylinder 8.

[0043] The parts to be processed are pre-loaded into pallets 7, which are neatly stacked in the shelf 9. Each pallet 7 has a slot on its edge to engage with the protruding end of the limit cylinder 8, providing stable positioning and preventing the pallet 7 from moving or tilting. The lifting mechanism pushes the pallets 7 up layer by layer to facilitate the transplanting operation.

[0044] Working Principle: The entire process from loading to unloading of workpieces is achieved through the loading mechanism 1, unloading mechanism 3, transfer mechanism 4, and dispensing mechanism 2. The loading mechanism 1 and unloading mechanism 3 are identical. During loading, the lifting cylinder holds the stacked pallets 7 in place, while the limiting cylinder 8 retracts, releasing the limiting effect on pallets 7. The lifting cylinder then descends, causing the bottom pallet 7 to fall onto the conveyor belt of the transfer mechanism 4, i.e., the loading station. Simultaneously, the telescopic rod of the limiting cylinder 8 extends and inserts into the corresponding slot of the pallet 7. The remaining trays 7 are limited and lowered. Under the transmission of the transfer mechanism 4, the trays 7 move to the processing station. After processing, they are conveyed to the unloading station of the unloading mechanism 3. The telescopic rod of the limit cylinder 8 of the unloading mechanism 3 retracts, canceling the overall limitation on the stacked trays 7. The lifting cylinder periodically lifts the trays 7, raising the bottom tray 7 to the height of the limit cylinder 8. The telescopic rod of the limit cylinder 8 extends and cooperates with the slot of the tray 7 to re-limit. The above actions are repeated to realize fully automatic dispensing.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
