Description

Technical Field

[0001] The utility model belongs to the technical field related to eccentric shaft sleeve modules, and specifically relates to an eccentric shaft sleeve module. Background Art

[0002] The eccentric shaft and sleeve module is a component used in mechanical transmission systems, usually used to transmit rotational motion. It consists of an eccentric shaft and a sleeve. The eccentric shaft is a part with an eccentricity on the shaft, and the sleeve is a component sleeved on the eccentric shaft. When the eccentric shaft rotates, due to the eccentric position of the eccentric shaft, the sleeve will produce eccentric motion, thereby achieving the purpose of transmitting rotational motion. This module is often used in mechanical transmission systems that require speed or position changes.

[0003] During the automated assembly of electronic products, it is sometimes necessary to lift the outer sleeve a certain distance to expose the inner core of the sleeve. Existing sleeve lifting technologies on the market mostly use direct lifting by a cylinder. This method may result in undesirable design results or relatively complex structural design due to the excessive stroke of the cylinder. Utility Model Content

[0004] The purpose of the utility model is to provide an eccentric shaft sleeve module to solve the problem that in the automated assembly process of electronic products proposed in the above background technology, it is sometimes necessary to lift the outer sleeve for a certain distance to expose the inner core of the sleeve. Most of the existing sleeve lifting technologies on the market are direct lifting by cylinders. This method may lead to design results that are not required by the design or relatively complex structural design problems due to the excessive stroke of the cylinder.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an eccentric shaft sleeve module, comprising an eccentric shaft assembly, a blade-type rotary cylinder is installed at the left position of the eccentric shaft assembly, a mounting block is installed at the inner position of the blade-type rotary cylinder, a gear is installed at the inner position of the mounting block, an eccentric shaft body is installed at the right end position of the gear, a fixing assembly is installed at the right end position of the mounting block, a docking hole and a slot are provided at the upper end position of the fixing assembly, a sleeve is installed at the inner position of the fixing assembly, the lower end position of the sleeve is an inner core, and the upper end position of the sleeve is provided with a mounting hole.

[0006] Preferably, a coupling is connected to the right end of the blade-type rotary cylinder.

[0007] Preferably, the blade-type rotary cylinder is connected to a gear via a connecting shaft, and the rotation of the gear causes the eccentric shaft to rotate.

[0008] Preferably, the blade-type rotary cylinder, the mounting block, the gear, the eccentric shaft and the coupling constitute an eccentric shaft assembly.

[0009] Preferably, a fixing component is installed at the right end of the mounting block.

[0010] Preferably, the fixing assembly is installed with a disc spring assembly at the upper end position through the docking hole.

[0011] Preferably, a sleeve is installed at an inner position of the fixing assembly, and the sleeve is installed with the pipe joint through a mounting hole at an upper end position.

[0012] Preferably, the sleeve, inner core and pipe joint form a suction nozzle assembly.

[0013] Compared with the prior art, the utility model provides an eccentric shaft sleeve module, which has the following beneficial effects:

[0014] The eccentric shaft sleeve has a simple structure, and only one eccentric shaft is needed to separate the sleeve and the core. Not only is the separation stroke small, but it can also move reciprocatingly. When the suction nozzle needs to receive a larger pressure, the sleeve can move with the eccentric shaft to cover the small material, thereby protecting the inner core of the sleeve. When it is necessary to observe the status of the suction nozzle and the small material, the inner core of the sleeve can also move with the eccentric shaft to expose a small part of the suction head and the small material. This design uses an eccentric shaft to drive the entire sleeve structure to move up and down. It has a simple structure and a small movement stroke. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4 An eccentric shaft sleeve module shown in the figure includes an eccentric shaft component 1, a blade type rotary cylinder 2 is installed at the left position of the eccentric shaft component 1, a mounting block 3 is installed at the inner position of the blade type rotary cylinder 2, a gear 11 is installed at the inner position of the mounting block 3, an eccentric shaft body 9 is installed at the right end position of the gear 11, a fixing component 6 is installed at the right end position of the mounting block 3, a docking hole 5 and a slot 10 are provided at the upper end position of the fixing component 6, a sleeve 7 is installed at the inner position of the fixing component 6, an inner core 8 is provided at the lower end position of the sleeve 7, and a mounting hole 4 is provided at the upper end position of the sleeve 7.

[0022] When the eccentric shaft assembly 1 rotates, the disc spring provides spring force, causing eccentric movement between the eccentric shaft and the sleeve, thereby realizing the function of transmitting rotational motion. The fixing assembly 6 ensures the stability of the entire module, and the nozzle assembly provides a connection interface so that the module can be effectively connected to other systems.

[0023] like Figure 2 and Figure 4 As shown, a coupling is connected at the right end of the blade type rotary cylinder 2, and the blade type rotary cylinder 2 is connected to the gear 11 through a connecting shaft. The rotation of the gear 11 causes the eccentric shaft 9 to rotate. The blade type rotary cylinder 2, the mounting block 3, the gear 11, the eccentric shaft 9 and the coupling constitute an eccentric shaft assembly 1. A fixing assembly 6 is installed at the right end of the mounting block 3. The fixing assembly 6 is installed with a disc spring assembly at the upper end through a docking hole 5. A sleeve 7 is installed at the internal position of the fixing assembly 6. The sleeve 7 is installed with the pipe joint through the mounting hole 4 at the upper end. The sleeve 7, the inner core 8 and the pipe joint constitute a suction nozzle assembly.

[0024] The eccentric shaft sleeve has a simple structure, and only one eccentric shaft is needed to separate the sleeve 7 and the core. Not only is the separation stroke small, but it can also move reciprocatingly. When the suction nozzle needs to receive a larger pressure, the sleeve 7 can move with the eccentric shaft to cover the small material, thereby protecting the inner core 8 of the sleeve 7. When it is necessary to observe the status of the suction nozzle and the small material, the inner core 8 of the sleeve 7 can also move with the eccentric shaft to expose a small part of the suction head and the small material. This design uses an eccentric shaft to drive the entire sleeve 7 structure to move up and down, with a simple structure and a small movement stroke.
