Description

Technical Field

[0001] The utility model relates to the technical field of high-speed chip mounters, and more specifically to a chip surface cleaning mechanism for high-speed chip mounters. Background Art

[0002] The placement machine is also called the placement machine or surface mount system. In the production line, it is configured after the dispensing machine or screen printing machine. It is a device that accurately places surface mount components on the PCB pads by moving the placement head. High-speed placement machines are widely used in the field of electronic placement technology for their advantages such as fast placement speed, accurate placement, high degree of automation, and stable quality. When the high-speed placement machine is working, the surface of the patch needs to be cleaned by a cleaning mechanism.

[0003] For example, CN216937251U discloses a patch surface cleaning device for a high-speed patch machine, the main points of its technical solution are: it includes a patch and a shell, the two end sides of the shell are provided with an output port and an input port, the patch enters from the input port and exits from the output port, a motor is fixed to the outer side wall of the shell, an upper cleaning cylinder and a lower cleaning cylinder are rotatably connected to the side wall of the shell, a cleaning mechanism is arranged on the upper cleaning cylinder and the lower cleaning cylinder, an outer side end of the upper cleaning cylinder is coaxially fixed with the output end of the motor, the upper cleaning cylinder and A belt roller is coaxially fixed to the outer end of the lower cleaning cylinder, and the outer surfaces of the two belt rollers are commonly covered with belts. The patch passes through between the upper cleaning cylinder and the lower cleaning cylinder, and a suction machine is fixed to the outer wall of the shell. A connecting pipe is fixed to the output end of the suction machine, and a collecting mechanism is connected between the connecting pipe and the cleaning mechanism. When the sucked dust is processed, the dust is sucked into the collection box through the ventilation pipe, and the dust filter plate collects, filters and intercepts the dust in a centralized manner. Opening the cover plate facilitates the centralized collection and cleaning of the dust, and the dust cleaning is convenient.

[0004] The above-mentioned surface cleaning mechanism for a high-speed placement machine still has certain shortcomings: since the cleaning mechanism is arranged horizontally with the placement head, once the cleaning mechanism comes into contact with the object to be placed, the cleaning mechanism will be unable to clean the surface of the object, and once the collision force is too great, the cleaning mechanism will be damaged. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a patch surface cleaning mechanism for a high-speed patch machine to solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a patch surface cleaning mechanism for a high-speed patch machine, comprising a mounting block, the lower surface of the mounting block is symmetrically and detachably mounted with two patch heads along the center, the lower surface of the mounting block is symmetrically and inlaidly mounted with two cleaning components along the center, the upper surface of the mounting block is symmetrically and detachably mounted with multiple laying components along the center, and the lower surface of the cleaning component is provided with an anti-touch component.

[0007] Wherein, the outer surface of the mounting block is connected to the interior of the high-speed placement machine, and the cross-sectional area of ​​the anti-touch component is larger than the cross-sectional area of ​​the cleaning component.

The side wall of the installation frame is fixedly connected to the protective mesh plate, the other side wall of the installation frame is fixedly connected to the mounting frame, and a bearing is embedded and installed at the center of the side wall of the mounting frame.

[0009] Among them, a motor is detachably installed in the middle of the side wall of the mounting frame, one end of the motor is connected to a power connection line through a laying component, the other end of the motor is fixedly installed with a connecting shaft through the bearing, and one end of the connecting shaft is detachably installed with three fan blades in a circular array.

[0010] The anti-touch assembly comprises an anti-touch frame, telescopic rods and buffer springs. Four telescopic rods are fixedly mounted on the side wall of the anti-touch frame in a rectangular array, and buffer springs are fixedly sleeved on the outer surfaces of the telescopic rods.

[0011] Wherein, one end of the telescopic rod is fixedly connected to a second connecting plate, and a side wall of the second connecting plate is connected to one side of the lower surface of the mounting block.

[0012] The laying assembly comprises a limit frame, connecting rods and laying wheels. Two connecting rods are movably sleeved along the center symmetrically inside the limit frame, and the laying wheels are movably sleeved in the middle of the outer surface of the connecting rods.

[0013] Wherein, the side wall of the connecting rod is fixedly connected with a first connecting disk, the side wall of the first connecting disk is fixedly connected with a return spring, and the side wall of the limiting frame is connected to one side of the upper surface of the mounting block.

[0015] 1. In the above scheme, the patch surface cleaning mechanism is provided with a laying component. When the cleaning component is connected to the mounting block, the two groups of connecting rods inside the laying component are stretched outward. When stretched to a certain distance, one end of the power connection line is passed through the center of the two groups of laying wheels and connected to one end of the motor, and then the two groups of connecting rods are slowly loosened. Then the reset spring will restore the two groups of connecting rods to their original positions, so that the two groups of laying wheels limit the position of the power connection line to avoid the power connection line from being entangled with other objects, thereby enhancing the practicality of the device;

[0016] 2. In the above scheme, the patch surface cleaning mechanism is provided with an anti-touch component. When it is necessary to clean the surface of the object to be patched, the mounting block connected to the high-speed patch machine will move downward until the patch head contacts the surface of the object. At this time, the cleaning component will also move downward, and then the anti-touch component provided on the surface of the cleaning component will replace the lower surface of the cleaning component to contact the surface of the object, so as to avoid the lower surface of the cleaning component from fitting with the surface of the object, thereby ensuring that the cleaning component can work normally. Because the anti-touch component is provided with a telescopic rod and a buffer spring inside, when the anti-touch frame contacts the surface of the object, the telescopic rod and the buffer spring can partially offset the external force exerted on the anti-touch frame, so as to ensure the quality of the cleaning component, thereby enhancing the practicability of the device.

[0027] The outer surface of the mounting block 1 is connected to the interior of the high-speed placement machine. The cross-sectional area of ​​the anti-touch component 5 is larger than the cross-sectional area of ​​the cleaning component 3.

[0028] Benefits: The provision of the cleaning component 3 is helpful for cleaning the surface of the object to be patched, thereby enhancing the practicability of the device.

[0029] The working process of the utility model is as follows:

[0030] When the cleaning mechanism is working, in order to avoid the power connection line 36 from getting entangled during use, a laying component 4 is provided. After the cleaning component 3 is connected to the mounting block 1, the two groups of connecting rods 42 inside the laying component 4 are stretched outward. After being stretched to a certain distance, one end of the power connection line 36 is passed through the center of the two groups of laying wheels 43 and connected to one end of the motor 35. Then the two groups of connecting rods 42 are slowly loosened, and then the reset spring 45 restores the two groups of connecting rods 42 to their original positions, so that the two groups of laying wheels 43 limit the position of the power connection line 36 to avoid the power connection line 36 from getting entangled with other objects, thereby enhancing the practicability of the device.

[0031] In the above scheme, when the cleaning mechanism is working, in order to ensure the cleaning effect of the device, an anti-touch component 5 is provided. When the surface of the object to be patched needs to be cleaned, the mounting block 1 connected to the high-speed patch machine will move downward until the patch head 2 is in contact with the surface of the object. At this time, the cleaning component 3 will also move downward, and then the anti-touch component 5 provided on the surface of the cleaning component 3 will replace the lower surface of the cleaning component 3 to contact the surface of the object, so as to avoid the lower surface of the cleaning component 3 from being in contact with the surface of the object, thereby ensuring that the cleaning component 3 can work normally. Because the anti-touch component 5 is provided with a telescopic rod 52 and a buffer spring 53 inside, when the anti-touch frame 51 is in contact with the surface of the object, the telescopic rod 52 and the buffer spring 53 can partially offset the external force exerted on the anti-touch frame 51, so as to ensure the quality of the cleaning component 3, thereby enhancing the practicability of the device.
