Description

Technical Field

[0001] This utility model relates to the technical field of flexible circuit board production and processing equipment, and in particular to a self-cleaning chip mounting and feeding mechanism. Background Technology

[0002] Circuit designs are embedded in flexible, thin, bendable plastic sheets to create flexible circuit boards, which are characterized by high wiring density, light weight, thinness, and good bending properties. Processing equipment is mounted along the side of the conveyor to perform surface mounting, inspection, and other operations on the flexible circuit boards, completing the surface mounting process.

[0003] The feeding mechanism picks up and feeds materials onto the chip mounting production line through a feeding end, such as a suction cup, a negative pressure gripper, or a robotic arm. In the processing equipment system environment, dust and foreign objects in the environment are easily attracted to the feeding end and can easily enter the negative pressure air circuit. Long-term accumulation can easily cause blockage in the narrow air circuit. Furthermore, dust or foreign objects remaining on the feeding end can easily contaminate or damage the materials (chips), leading to product scrap. The cleaning problem of the feeding end is easily overlooked. When problems occur, the production line is shut down, and manual inspection and cleaning are required, which increases the equipment operation and maintenance costs and affects the production efficiency of the production line.

[0004] To address the problems in the existing technology, this utility model provides a self-cleaning patch feeding mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning chip mounting feeding mechanism to solve the technical problem that the feeding end of existing chip mounting equipment lacks a matching automated cleaning function, which easily leads to product contamination and damage.

[0006] The technical solution of this utility model is: a self-cleaning chip mounting feeding mechanism, including a feeding mechanism disposed on one side of the chip mounting production line, the feeding mechanism feeding materials to the chip mounting station on the chip mounting production line, the feeding head of the feeding mechanism moving back and forth between the material platform and the chip mounting station to feed the materials on the material platform to the chip mounting station.

[0007] A cleaning component is provided between the feeding mechanism and the placement station. When there is no material, the gripping end face of the gripping head moves on the cleaning platform of the cleaning component to achieve friction cleaning.

[0008] Preferably, the cleaning component is independently installed between the feeding mechanism and the patch placement station, or the cleaning component is fixedly connected to the side of the patch placement station;

[0009] The cleaning component includes the cleaning platform, which is mounted on the moving trajectory of the gripper head via a support. When the cleaning platform is close to the side of the placement station, the support is fixed to the side of the placement station via a connecting part.

[0010] Preferably, the gripping head moves in a straight line on the cleaning platform at least once along the same direction; the gripping head moves back and forth in a straight line on the cleaning platform several times; the movement trajectory of the gripping head on the cleaning platform is a curve or a combination of curves and straight lines.

[0011] Preferably, the cleaning platform is configured as a planar structure or a curved structure, and the surface of the cleaning platform is covered with a flexible cleaning fabric. The curved structure is constructed by the partial wall of the dome or the sidewall of the roller or the spherical sidewall.

[0012] Preferably, after the material gripper head is cleaned, the cleaning platform can rotate or flip to switch to a new end face to become the cleaning platform.

[0013] Preferably, a detection head is provided between the feeding mechanism and the patch station to detect the material loading status of the gripping head, and the detection head is equipped with a light source.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] This invention sets up a cleaning platform between the chip mounting station and the feeding mechanism. After the feeding mechanism's gripper head finishes loading, it can self-clean itself by rubbing on the cleaning platform during its return journey, removing dust and foreign objects without stopping the machine. The cleaning process does not require manual intervention, keeping the end face of the gripper head clean and maintaining the gripper head's "gripping force" on the material quickly and efficiently.

[0022] The present invention will be further described in detail below with reference to specific embodiments:

[0023] The chip mounter system is used for mounting flexible circuit boards. Within the system, the mounting line 2 has several processing stations, including a feeding mechanism, a rolling mechanism, a mounting mechanism, and a testing mechanism. For example... Figure 1 As shown, this utility model provides a self-cleaning chip mounting feeding mechanism. The feeding mechanism includes a feeding mechanism 3 disposed on one side of the chip mounting production line 2. Chip rolls are spread and fed on the surface of the material platform 32 of the feeding mechanism 3. The gripping head 31 of the feeding mechanism 3 moves back and forth between the material platform 32 and the chip mounting station 21 to feed the material on the material platform 32 onto the chip mounting station 21 of the chip mounting production line 2.

[0024] See attached document Figure 2 As shown, the gripping head 31 is moved by a three-dimensional linear module 33. In other embodiments, the gripping head can also be driven by a multi-axis robotic arm.

[0025] A cleaning component 1 is installed between the feeding mechanism 3 and the placement station 21. In the empty state, the gripping end face of the gripping head 31 moves on the cleaning platform 11 of the cleaning component 1 to achieve friction cleaning. The layout of the feeding mechanism 3 in the placement line 2 is shown in the attached figure. Figure 1 As shown.

[0026] The cleaning component 1 is independently installed between the feeding mechanism 3 and the placement station 21, or the cleaning component 1 is fixedly connected to the side of the placement station 21. (See attached image) Figure 2 As shown, a schematic diagram is provided showing that the cleaning component 1 is fixedly connected to the side of the patch station 21. The cleaning component 1 is close to the patch station 21, and the distance between the devices is small, which reduces the overall system size.

[0027] Furthermore, a detection head 4 is installed between the feeding mechanism 3 and the placement station 21 to detect the material loading status of the gripping head 31. A light source 5 is installed above the detection sleeve, as shown in the attached diagram. Figure 3 As shown, a ring of light is installed via a ring-shaped support ring.

[0028] The cleaning component 1 is fixedly connected to one side of the placement station 21. The cleaning component 1 will be described in detail below.

[0029] The cleaning component 1 includes a cleaning platform 11, which is mounted on the moving track of the gripper head 31 via a support 12. The support 12 is fixed to the side of the placement station 21 via a connecting part 13.

[0030] In one embodiment or other implementation, the cleaning platform 11 is configured as a planar structure. For example, the cleaning platform 11 adopts a polygonal block structure, with one side facing the end face of the gripping head 31 as one of its sides.

[0031] In another embodiment or other implementation, the cleaning platform 11 is configured as a curved structure, for example, the curved structure is constructed by the partial wall of a dome or the sidewall of a roller or a spherical sidewall.

[0032] Regardless of whether the cleaning platform 11 has a planar or curved structure, its surface is covered with a flexible cleaning fabric. The gripping head 31 moves in a straight line on the cleaning platform 11 at least once in the same direction; or the gripping head 31 moves back and forth in a straight line on the cleaning platform 11 several times; or the movement trajectory of the gripping head 31 on the cleaning platform 11 is a curve or a combination of curves and straight lines.

[0033] Furthermore, in two or other embodiments, the cleaning platform 11 can rotate or flip to switch to a new end face as the cleaning platform 11 after the gripping head 31 has finished cleaning. Also, when the cleaning platform adopts a polygonal structure, the polygonal edges can also serve as the cleaning platform 11.

[0034] Specifically, cleaning component 1 includes a cleaning platform 11, as shown in the attached diagram. Figure 4 As shown in the schematic diagram of an embodiment, in this embodiment, the cleaning platform 11 is formed by the partial cylindrical curved surface of rollers 111. The two end faces of the rollers 111 are fixed to the seat plate 113 via support shafts 112. The support portion 12 at the bottom of the seat plate 113 uses two support columns (two support columns are shown in the figure, but it is foreseeable that the number of support columns is not unique). These support columns can be fixedly installed using fixed rods, or they can be telescopic rods / columns to adjust the height of the cleaning platform 11. The connecting portion 13 uses a horizontal plate, the horizontal width of which is related to the compactness between the devices. The horizontal plate can be a fixed plate or a telescopic plate with adjustable horizontal width.

[0035] By setting a cleaning component 1 between the chip placement station 21 and the feeding mechanism 3, the gripping head 31 can self-clean by rubbing on the cleaning platform after releasing the material, removing dust and foreign objects without stopping the machine. The cleaning process does not require manual intervention, keeping the end face of the gripping head 31 clean, so as to maintain the gripping force of the gripping head 31 on the material.

[0036] In this embodiment, by considering the relative relationship between the layout components, the material gripper 31 directly accepts inspection during the material picking process. Since the feeding end of the material platform 32, the chip mounting station 21, the inspection head 4, and the cleaning platform are kept in the same straight extension direction, there is no need to rotate and adjust the angle of the material gripper 31 or move the material gripper 31 in a zigzag manner. This can save the time of stopping to accept inspection and the time of rotating and adjusting the angle of the material gripper, thereby improving efficiency. In addition, the structure between the equipment components is more compact, reducing the size of the equipment.

They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
