Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, and in particular to an automatic dispensing device. Background Technology

[0002] In modern industrial production, dispensing is a crucial step in product manufacturing and is widely used in various industries such as electronic component packaging, automotive parts bonding, medical device assembly, and aerospace component sealing. The precision, efficiency, and stability of dispensing operations directly affect the final quality and performance of products. With the continuous improvement of industrial automation, traditional manual dispensing methods, due to their low efficiency, difficulty in controlling precision, and high labor intensity, can no longer meet the needs of large-scale, high-quality production. Therefore, automatic dispensing devices have gradually become the mainstream choice in industrial production.

[0003] However, in the automatic dispensing process for strip-shaped workpieces (such as cables, strip materials, etc.), the feeding process has always been a problem that needs to be solved. Due to the slender and continuous characteristics of strip-shaped workpieces, problems such as entanglement, knotting or inaccurate positioning are prone to occur during the feeding process. Some devices manually place the strip-shaped workpieces at the dispensing position, which is not only inefficient, but also prone to human error, affecting the dispensing quality.

[0004] To address the aforementioned issues, this technical solution proposes a novel automatic dispensing device that enables efficient dispensing of strip-shaped workpieces. This solves the problem of low efficiency in the material loading stage of existing automatic dispensing devices, improves the automation level and production efficiency of dispensing operations, and provides a more efficient and reliable dispensing solution for modern industrial production.

[0009] As a further embodiment of this utility model: the winding assembly further includes a locking nut and a winding cylinder, the winding cylinder being movably connected to the outer wall of the mounting rod, and the locking nut and one end of the mounting rod being connected by threads.

[0010] As a further embodiment of this utility model: the clamping assembly includes a vertical plate fixed to the outer wall of the top of the base and a fixing mechanism. The fixing mechanism includes a guide rod and a guide plate. The guide plate is welded to the side wall of the vertical plate, and the guide rod is movably connected to the inner wall of the through hole opened on the surface of the guide plate. A bracket is welded to one end of the guide rod, and a clamping plate is welded to the inner wall of the bracket.

[0011] As a further embodiment of this utility model: a side plate is fixed to one side of the outer wall of the upright plate, and an electric telescopic rod five is fixed to one side of the outer wall of the side plate. The output end of the electric telescopic rod five is fixed to a connecting frame by a pin, and a swing arm is movably connected between the inner wall of the connecting frame and the inner wall of the bracket.

[0012] As a further embodiment of this utility model: the clamping assembly 2 includes a movable seat and an electric telescopic rod 1.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] An automatic dispensing device, designed to facilitate material loading during the dispensing process, such as... Figures 1 to 6 As shown, the device includes a base 1, a winding assembly and a dispensing assembly installed on the top outer wall of the base 1, and a strip workpiece 2 to be dispensed with adhesive wound on the winding assembly. A clamping assembly 1 for clamping the strip workpiece 2 is installed on the top outer wall of the base 1, and a liner plate 27 is fixed to the top outer wall of the base 1 by bolts. An electric telescopic rod 25 is fixed to one side outer wall of the liner plate 27 by bolts, and a clamping assembly 2 for clamping the strip workpiece 2 is installed at the output end of the electric telescopic rod 25.

[0031] The winding assembly can be used to wind the strip workpiece 2 that needs to be glued. When it is necessary to apply glue to the surface of the strip workpiece 2, in the initial state, the upper and lower sides of the strip workpiece 2 are initially clamped by the clamping assembly 1. Then, the electric telescopic rod 2 5 drives the clamping assembly 2 to move forward, so that the clamping assembly 2 moves towards the end of the strip workpiece 2. When the clamping assembly 2 moves to the end of the strip workpiece 2, it clamps and fixes the end of the strip workpiece 2. At this time, the clamping assembly 1 disconnects from the clamping and fixing of the strip workpiece 2. When the electric telescopic rod 2 5 drives the clamping assembly 2 to make a return movement, the strip workpiece 2 is unwound along the winding assembly. After the strip workpiece 2 is unwound a set distance, the clamping assembly 1 clamps and fixes the upper and lower sides of the strip workpiece 2 again, so that the glue application assembly applies glue to the surface of the strip workpiece 2 clamped between the clamping assembly 1 and the clamping assembly 2.

[0032] The winding assembly includes a mounting rod 8 and a vertical plate 9. The vertical plate 9 is fixed to the top outer wall of the base 1 by bolts, and the mounting rod 8 is rotatably connected to the inner wall of the through hole opened on the side of the vertical plate 9. A coil spring 7 is installed between the outer circumference of the mounting rod 8 and the side wall of the vertical plate 9. A limit plate 24 is welded to the outer circumference of the mounting rod 8. The winding assembly also includes a locking nut 25 and a winding cylinder 30. The winding cylinder 30 is slidably connected to the outer wall of the mounting rod 8, and the locking nut 25 and one end of the mounting rod 8 are connected by threads.

[0033] The winding drum 30 can be used to wind the strip workpiece 2. When it is necessary to fix the winding drum 30 and the mounting rod 8, the winding drum 30 is slid along the outer wall of the mounting rod 8 so that the winding drum 30 and the side of the limiting plate 24 are in contact. Then, the locking nut 25 is threadedly connected to the mounting rod 8, thereby locking the winding drum 30 with the locking nut 25 and the limiting plate 24. The coil spring 7 ensures that the strip workpiece 2 is always in a taut state during the unwinding process.

[0034] The clamping assembly includes a vertical plate 6 fixed to the top outer wall of the base 1 by bolts and a fixing mechanism. The fixing mechanism includes a guide rod 17 and a guide plate 20. The guide plate 20 is welded to the side wall of the vertical plate 6, and the guide rod 17 is slidably connected to the inner wall of the through hole opened on the surface of the guide plate 20. A bracket 21 is welded to one end of the guide rod 17, and a clamping plate 3 is welded to the inner wall of the bracket 21. A side plate 18 is fixed to one side outer wall of the vertical plate 6 by bolts, and an electric telescopic rod 19 is fixed to one side outer wall of the side plate 18 by bolts. A connecting frame 23 is fixed to the output end of the electric telescopic rod 19 by a pin, and a swing arm 22 is rotatably connected between the inner wall of the connecting frame 23 and the inner wall of the bracket 21.

[0035] The electric telescopic rod 19 can drive the connecting frame 23 to move laterally. The two sets of swing arms 22 convert the lateral movement of the connecting frame 23 into the linear movement of the two sets of brackets 21 and guide rods 17 along the guide plate 20. This allows the upper and lower outer walls of the strip workpiece 2 to be clamped and fixed during the relative movement between the two sets of clamping plates 3.

[0036] The clamping assembly 2 includes a movable seat 26 and an electric telescopic rod 4. The movable seat 26 is fixed to the output end of the electric telescopic rod 5 by a pin, and the two sets of electric telescopic rods 4 are respectively fixed to the top outer wall and bottom outer wall of the movable seat 26 by bolts. The output end of the electric telescopic rod 4 is fixed to a lifting frame 28 by a pin, and the inner wall of the lifting frame 28 is fixed to a clamping plate 29 by bolts.

[0037] When it is necessary to clamp and fix the end of the strip workpiece 2, when the electric telescopic rod 25 drives the two sets of clamping plates 29 to move to the upper and lower sides of the end of the strip workpiece 2, the two sets of liner plates 27 respectively drive the corresponding clamping plates 29 to make progress movements, so that the two sets of clamping plates 29 clamp and fix the upper and lower sides of the end of the strip workpiece 2 after relative movement.

[0038] The dispensing assembly includes an electric telescopic rod 12 and a fixing plate 13. The fixing plate 13 is fixed to the top outer wall of the base 1 by bolts, and the electric telescopic rod 12 is fixed to one side outer wall of the fixing plate 13 by bolts. The output end of the electric telescopic rod 12 is fixed to an L-shaped plate 11 by pins. The top outer wall of the L-shaped plate 11 is fixed to an electric telescopic rod 10 by bolts. The output end of the electric telescopic rod 10 is fixed to a U-shaped plate 16 by pins. The top inner wall of the U-shaped plate 16 is fixed with a dispensing head 15.

[0039] The position of the dispensing head 15 can be adjusted in the horizontal direction by the electric telescopic rod 12, and the position of the dispensing head 15 can be adjusted in the vertical direction by the electric telescopic rod 10, which facilitates the adjustment of the dispensing position on the strip workpiece 2. The dispensing process and principle of the dispensing head 15 are existing technologies and will not be described in detail here.

[0040] The bottom inner wall of the U-shaped plate 16 is fixed with a cutting blade 14 by bolts;

[0041] When the electric telescopic rod 310 drives the dispensing head 15 to move downward, the dispensing head 15 moves to a position close to the surface of the strip workpiece 2 to dispense glue. After the dispensing head 15 finishes dispensing, the electric telescopic rod 310 drives the dispensing head 15 to move upward, so that the cutting blade 14 can move upward simultaneously to cut the strip workpiece 2 from the bottom, which facilitates the subsequent dispensing operation on the strip workpiece 2 wound on the winding drum 30.

[0042] A rectangular plate 31 is fixed to the top outer wall of the base 1 by bolts, and a guide roller 32 is rotatably connected between the two rectangular plates 31.

[0043] The guide roller 32 can be used to guide and direct the movement path of the strip workpiece 2.

[0044] Working principle: The winding drum 30 winds the strip workpiece 2 that needs to be glued. The winding drum 30 slides along the outer wall of the mounting rod 8, so that the winding drum 30 is in contact with the side of the limiting plate 24. The locking nut 25 is threaded to the mounting rod 8, and the winding drum 30 is locked by the locking nut 25 and the limiting plate 24. The coil spring 7 ensures that the strip workpiece 2 is always in a tensioned state during the unwinding process. In the initial state, the clamping assembly 1 clamps the upper and lower sides of the strip workpiece 2, clamping and fixing the outer walls of the upper and lower sides of the strip workpiece 2. The electric telescopic rod 25 drives the clamping assembly 2 to move forward, so that the clamping assembly 2 moves towards the end of the strip workpiece 2. When the clamping assembly 2 moves to the end of the strip workpiece 2, the two sets of electric telescopic rods 1 and 4 drive the corresponding clamping plates 29 to move forward, so that the two sets of clamping plates 29 move relative to each other and clamp and fix the upper and lower sides of the end of the strip workpiece 2. At this time, the clamping assembly Once the clamping and fixing of the strip workpiece 2 is disconnected, the electric telescopic rod 25 drives the clamping assembly 2 to perform a return motion, causing the strip workpiece 2 to be unwound along the winding assembly. After the strip workpiece 2 is unwound a set distance, the clamping assembly 1 clamps and fixes the upper and lower sides of the strip workpiece 2 again. The dispensing assembly dispenses glue onto the surface of the strip workpiece 2 clamped between the clamping assembly 1 and the clamping assembly 2. During dispensing, the electric telescopic rod 4 12 can adjust the position of the dispensing head 15 in the horizontal direction, and the electric telescopic rod 3 10 can adjust the position of the dispensing head 15 in the vertical direction, so as to adjust the dispensing position on the strip workpiece 2. When the electric telescopic rod 3 10 drives the dispensing head 15 to move down to a position close to the surface of the strip workpiece 2 for dispensing, after the dispensing is completed, the electric telescopic rod 3 10 drives the dispensing head 15 to move up, and at the same time, the cutting blade 14 moves up synchronously to cut the strip workpiece 2 from the bottom, which facilitates the subsequent dispensing operation on the strip workpiece 2 wound on the winding drum 30.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
