Description

Technical Field

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

[0002] In the assembly of barrel-shaped workpieces on automated production lines, the spatial transition and motion mode connection between the workpiece and the turntable can affect production efficiency and product quality. In traditional production lines, conveyor belts typically use linear motion to continuously and stably transport workpieces between stations; while turntables rely on rotational motion to improve processing efficiency. However, when a barrel-shaped workpiece switches directly from a linear conveyor belt to a rotating turntable, the abrupt changes in speed, acceleration, and direction between the two motion modes cause dynamic interference between the workpiece and the equipment, leading to jamming. Simultaneously, the sudden change in motion mode can also cause a decrease in workpiece positioning accuracy, resulting in axial offset or radial misalignment, which in turn affects the accuracy of subsequent assembly processes. Utility Model Content

[0003] The purpose of this invention is to provide an automatic workpiece assembly device to solve the problems of offset and misalignment of workpieces during transfer between conveyor belts and turntables in the prior art.

[0004] The technical solution of this utility model is: an automatic workpiece assembly device, comprising: frame; A conveyor belt, mounted on the frame, is used to transport workpieces along a first direction; A turntable is rotatably mounted on the frame and adjacent to one side of the conveyor belt, and the turntable has a plurality of pressing components for mounting workpieces distributed in a circumferential array. A limiting component, fixed to the frame and located above the conveyor belt, is used to guide the workpieces conveyed on the conveyor belt. The first guide member and the second guide member are rotatably connected to the frame on both sides of the limiting part. The first guide member drives the workpiece to be installed to move from the conveyor belt to the turntable, and the second guide member drives the installed workpiece to move from the turntable to the conveyor belt.

[0005] Preferably, the limiting member has a first guiding arc surface facing the input end of the conveyor belt, and the first guiding member has a corresponding first limiting groove. The workpiece conveyed from the input end of the conveyor belt is guided to the turntable along the first guiding arc surface under the combined limiting action of the first limiting groove and the first guiding arc surface.

[0006] Preferably, the limiting member is provided with a second guiding arc surface facing the output end of the conveyor belt, and the second guide member is provided with a second limiting groove. The second limiting groove and the second guiding arc surface jointly limit the workpiece on the turntable to be transferred to the output end of the conveyor belt along the second guiding arc surface.

[0007] Preferably, the top of the turntable is provided with a plurality of positioning plates arranged in a circular array, the positioning plates corresponding to the pressing assembly and used for radial positioning of the workpiece.

[0008] Preferably, a drive shaft is fixed at the rotation center of the turntable, the drive shaft extends upward and is fixedly connected to a support plate, and multiple pressing components are mounted on the support plate and located above the turntable.

[0009] Preferably, the pressing assembly includes: A drive cylinder, the cylinder body of which is fixed on the support plate, and the piston rod of which extends and retracts downward in the vertical direction; A movable disk is fixed to the end of the piston rod of the drive cylinder; Several telescopic components are installed at the bottom of the movable disk, and an upper pressure plate is connected to its end for pressing workpieces.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "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.

[0018] like Figure 1As shown, an automatic workpiece assembly device includes a frame 1, a conveyor belt 2, and a turntable 3. The conveyor belt 2 is fixed on the frame 1 and is used to transport workpieces 100 along a first direction. The turntable 3 is rotatably connected to the frame 1, and a plurality of pressing components 4 for mounting the workpieces 100 are distributed in a circular array on the turntable 3, for mounting the barrel body and barrel lid of the workpiece 100 into one piece. A limiting member 5 is fixed on the frame 1, located above the conveyor belt 2, with the input end and output end of the conveyor belt 2 located on both sides of the limiting member 5. A first guide member 6 and a second guide member 7 are rotatably connected to the frame 1, respectively located on both sides of the limiting member 5, to cooperate with the limiting member 5 to transfer the workpieces 100 between the conveyor belt 2 and the turntable 3.

[0019] like Figure 2 As shown, the limiting member 5 is provided with a first guiding arc surface. Preferably, the first guiding arc surface is a circular arc contour line. The input end of the first guiding arc surface is tangent to the first direction, and the output end of the first guiding arc surface is tangent to the second direction. The first guiding arc surface covers the conveyor belt 2, and the workpiece 100 at the input end of the conveyor belt 2 can move along the trajectory of the first guiding arc surface. In this embodiment, the first direction and the second direction are perpendicular in the horizontal plane. When the workpiece 100 leaves the conveyor belt 2 and enters the turntable 3, the change in its direction of movement and speed is a continuous and gradual process, rather than an abrupt zigzag turn. This avoids the workpiece 100 getting stuck, rolling, or shifting in position at the turning point due to inertia, ensuring smooth transfer.

[0020] The first guide member 6 is located between the limiting member 5 and the turntable 3. The first guide member 6 is constructed as a grooved wheel, and several first limiting grooves 61 are formed on the outer periphery of the first guide member 6. Preferably, the first guide member 6 has four first limiting grooves 61. Part of the first guide member 6 is located above the conveyor belt 2. When the workpiece 100 moves with the conveyor belt 2, the outer periphery of the workpiece 100 gradually comes into contact with the first limiting groove 61. The first guide member 6 drives the workpiece 100 to gradually deviate from the conveyor belt 2 along the direction of the first guiding arc surface, and transports the workpiece 100 to the turntable 3. During the turning process, the outer side of the workpiece 100 is abutted by the first guiding arc surface, and the inner side is embedded in the first limiting groove 61, thereby forming a precise positioning channel. This ensures that the workpiece 100 is always constrained by at least one guide surface during the process of leaving the conveyor belt 2, reducing the risk of the workpiece 100 deflecting, tipping, or getting stuck due to loss of constraint during the handover process.

[0021] like Figure 3 and Figure 4 As shown, the top of the turntable 3 is provided with multiple positioning plates 31, which are arranged in a circumferential array. Each positioning plate 31 corresponds one-to-one with each set of pressing components 4 to ensure that the pressing components 4 accurately install each accurately positioned workpiece 100. Preferably, a workpiece 100 is engaged between two adjacent positioning plates 31.

[0022] In this embodiment, a drive assembly 8 is provided at the bottom of the frame 1. The drive assembly 8 is connected to the turntable 3 via a transmission. In this embodiment, the drive assembly 8 is a motor. The motor drives the turntable 3 to rotate through a belt assembly and a gear assembly. In other embodiments, a harmonic reducer can be used for driving.

[0023] A drive shaft 32 is fixed at the rotation center of the turntable 3. The drive shaft 32 extends upward along the rotation axis of the turntable 3. A support plate 33 is fixed on the drive shaft 32. The support plate 33 is parallel to the turntable 3, and a gap is formed between the two. Several pressing components 4 are fixed in a circumferential array on the support plate 33, so that the pressing components 4 can face the workpiece 100.

[0024] The pressing assembly 4 includes a drive cylinder 41 and a moving plate 42. The cylinder body of the drive cylinder 41 is fixed on the support plate 33, and the piston rod of the drive cylinder 41 extends and retracts vertically downwards. The moving plate 42 is fixed to the end of the piston rod of the drive cylinder 41. Several telescopic components 9 are fixed to the end face of the moving plate 42 away from the drive cylinder 41, and an upper pressure plate 34 is provided at the end of the telescopic components 9. The several telescopic components 9 include a telescopic rod 91 and a spring 92. One end of the telescopic rod 91 is fixed to the bottom end face of the moving plate 42, and the other end is fixed to the top end face of the upper pressure plate 34. The spring 92 is sleeved on the telescopic rod 91. When the upper pressure plate 34 contacts the lid of the workpiece 100, the drive cylinder 41 can continue to descend a certain stroke, the spring 92 is compressed and provides continuous pressure to press the lid and the body of the workpiece into one piece. For a series of workpieces 100 with slightly different heights or installation depths, the pressing assembly 4 does not need to be reprogrammed or the cylinder stroke adjusted. It can automatically compensate for dimensional deviations, ensuring that each workpiece 100 can be pressed into place, which greatly improves the flexibility of production.

[0025] like Figure 2 As shown, the limiting member 5 is provided with a second guiding arc surface. The second guiding arc surface and the first guiding arc surface are respectively disposed on both sides of the limiting member 5 along the first direction. The second guiding arc surface is located on the side closer to the output end of the conveyor belt 2. Preferably, the second guiding arc surface is a circular arc contour line. The input end of the second guiding arc surface is tangent to the second direction, and the output end of the second guiding arc surface is tangent to the first direction. The second guiding arc surface covers the top of the conveyor belt 2. The second guide member transports the workpiece 100 of the turntable 3 onto the conveyor belt 2. The workpiece 100 can move along the trajectory of the second guiding arc surface.

[0026] The second guide member 7 is located between the limiting member 5 and the turntable 3. Several second limiting grooves 71 are formed on the outer periphery of the second guide member 7. The rotation direction of the second guide member 7 is opposite to that of the first guide member 6. Preferably, the second guide member 7 has four second limiting grooves 71. Part of the second guide member 7 is located above the conveyor belt 2. Under the guidance of the second guide member 7, the workpiece 100 installed on the turntable 3 is embedded into the second limiting groove 71. The second guide member 7 transfers the workpiece 100 from the turntable 3 to the conveyor belt 2 along the second guiding arc surface. The second guide member 7 smoothly and gradually guides the workpiece 100 from the rotational movement of the turntable 3 back to the linear movement of the conveyor belt 2, effectively avoiding the risk of the workpiece 100 being thrown away, tipped over, or stuck in the gap due to inertia or sudden change in direction when it leaves the turntable 3.
