Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a pickup apparatus, and a configuration diagram of the pickup apparatus according to the present embodiment after being disassembled is shown in fig. 1, and a configuration diagram of the pickup apparatus after being assembled is shown in fig. 2:
in particular, the pick-up device can be used for picking up metal particles on the surface of an object. In the present embodiment, the pickup device is mainly used to pick up the metal particles on the surface of the mask plate, but it is understood that the pickup device in the present embodiment can also be used to pick up the metal particles on the surface of other objects, for example: and metal residues in the preparation process of each film layer structure of the display panel can be adsorbed.
The pickup device includes: a magnetizing unit 1, and a pickup 2 connected to the magnetizing unit 1. The magnetization part 1 is used for magnetizing the pickup 2 so as to enable the pickup 2 to be magnetized, and therefore the pickup 2 can adsorb metal particles by utilizing the magnetism of the pickup 2, and the metal particles are picked up. Furthermore, the pickup device 2 can be used for picking up the residual metal particles on the surface of the mask plate, so that the problem that the yield is low when the display panel is prepared due to the metal particles on the surface of the mask plate is avoided; compared with the mode of removing the metal particles on the surface of the mask plate by using high-power laser equipment in the prior art, the pickup device in the embodiment has the advantages of low cost, extremely low loss when the metal particles are picked up, and long service life.
The picker 2 in this scheme includes: the bending portion 22 and the bending portion 22 are used for adsorbing metal particles, and the bending portion 22 of the pickup device 2 is used for adsorbing metal particles on the surface of the object, so that the end of the bending portion 22 is not easy to scratch the surface of the object, and therefore, when the pickup device in the embodiment is used for picking up the metal particles on the surface of the mask plate, the probability of damage to the surface of the object can be greatly reduced.
Wherein the material of the pickup 2 includes: neodymium iron boron, silicon steel, amorphous, nanocrystalline, ferrite, magnetic powder core and other magnetic materials. Preferably, if the pickup 2 is used for picking up the metal residue on the surface of the mask plate, the material of the pickup 2 may be the same as the material of the surface of the mask plate, so that the probability of damage to the surface of the mask plate caused by the pickup 2 can be greatly reduced. For example: if the mask plate surface material comprises nickel iron, then the material of the picker 2 also comprises nickel iron.
The pickup 2 further includes: and a fixing portion 21 connected between the magnetizing portion 1 and the bending portion 22.
As shown in fig. 3, the fixing portion 21 is flat, and the angle formed by the bending portion 22 and the fixing portion 21 at the junction is greater than 120 °, and the angle referred to herein is the angle formed by the tangent to the bending portion and the fixing portion at the junction and the fixing portion at the bending portion, i.e., the angle α in fig. 3.
Specifically, in the case where the length of the bending portion 22 is not changed, the tip of the bending portion 22 is located on the extension line of the fixing portion 21, and when the metal particles are adsorbed, the larger the included angle formed by the bending portion 22 and the fixing portion 21 at the connection point is, the larger the contactable area of the bending portion 22 and the surface of the mask plate is. When the included angle formed by the connection position of the bending portion 22 and the fixing portion 21 is greater than 120 degrees in the embodiment, the contact area between the bending portion 22 and the surface of the mask plate can be ensured to be appropriate, so that the bending portion 22 is ensured to have a good adsorption effect on metal particles. Preferably, the included angle formed by the bending portion 22 and the fixing portion 21 at the connection position, i.e. the angle α in fig. 3, is smaller than 135 °, so as to further ensure the adsorption effect of the bending portion 22 on the metal particles.
Further, as shown in fig. 3, the fixing portion 21 is flat, and the curved portion 22 has an arc-shaped surface. In a first direction perpendicular to the fixing portion 21 and toward the bending portion 22, which is an arrow direction shown in fig. 3, an angle between a tangent line of a lowest point of the bending portion 22 and a line connecting a tip of the bending portion 22 away from the fixing portion 21 and the lowest point of the bending portion 22, that is, an angle β in fig. 3, is greater than 30 °, thereby reducing a probability that the tip of the bending portion 22 away from the fixing portion 21 scratches the surface of the mask plate as much as possible.
Preferably, an angle between a tangent to the lowest point of the bent portion 22 and a line connecting a tip of the bent portion 22 away from the fixing portion 21 and the lowest point of the bent portion 22, i.e., an angle β in fig. 3, is less than 45 ° in the first direction. Because the smaller the included angle is, the larger the contactable area between the bending portion 22 and the surface of the mask plate is when the bending portion 22 is not changed in length, the included angle between the tangent line of the lowest point of the bending portion 22 and the connecting line between the end of the bending portion 22 away from the fixing portion 21 and the lowest point of the bending portion 22, which is set in the first direction in the present embodiment, is smaller than 45 °, not only can the probability that the end of the bending portion 22 away from the fixing portion 21 scratches the surface of the mask plate be reduced, but also the contactable area between the bending portion 22 and the surface of the mask plate can be ensured, so as to ensure the adsorption effect of the bending portion 22 on the metal particles.
The type of the bending portion 22 in fig. 2 and 3 of this embodiment is only for illustration, and should not be limited thereto, and in practical applications, as long as the bending portion 22 has an arc-shaped structure, the protruding surface of the arc-shaped structure is used to adsorb metal particles on the surface of the mask, which is not easy to scratch the surface of the mask.
It is noted that the cross-sectional shape of the curved portion 22 in the direction perpendicular to the length direction of the pickup 2 is circular, elliptical, or square with four corners having a curvature.
Specifically, this embodiment shows an implementation of the sectional shape of the curved portion 22 in the direction perpendicular to the longitudinal direction of the pickup 2, that is, the sectional shape of the curved portion 22 does not include corners, nor does it protrude in the circumferential direction, so that the side edges of the curved portion 22 are less likely to scratch the surface of the mask plate in the direction along the longitudinal direction of the pickup 2 when the curved portion 22 is placed on the surface of the mask plate to adsorb metal particles. It should be noted that the cross-sectional shape of the curved portion 22 in the present embodiment is only an example, and should not be limited to this, and in practical applications, the cross-sectional shape of the curved portion 22 along the length direction of the pickup 2 is not likely to scratch the surface of the mask as long as the cross-sectional shape does not include the corner.
In the case where the widest distance between any two points on the cross section of the curved portion 22 is not changed, in the direction perpendicular to the longitudinal direction of the pickup 2, the curved portion 22 having an elliptical cross section has a larger contact area with the surface of the mask plate than the curved portion 22 having a circular cross section, and thus has a better effect of adsorbing the metal particles; compared with the bending part 22 with the oval cross section, the bending part 22 with the square cross section having the radian at four corners has a larger contact area with the surface of the mask plate, and the bending part 22 has a better adsorption effect on the metal particles.
In addition, the widest distance between any two points on the cross section of the fixing portion 21 is larger than the widest distance between any two points on the cross section of the bending portion 22 in the direction perpendicular to the longitudinal direction of the pickup 2. For example: when the cross sections of the fixing portion 21 and the bending portion 22 are circular, the fixing portion 21 can support the bending portion 22 because the widest distance between any two points on the cross section of the fixing portion 21 is greater than the widest distance between any two points on the cross section of the bending portion 22, that is, the diameter of the fixing portion 21 is greater than the diameter of the bending portion 22.
Preferably, the widest distance between any two points on the cross section of the fixing portion 21 is greater than or equal to 0.8 mm, and the widest distance between any two points on the cross section of the bending portion 22 is between 0.5 mm and 0.65 mm. In the scheme, the widest distance between any two points on the section of the bending part 22 is 0.5-0.65 mm, so that the flexibility of the bending part 22 is ensured, and nano-level metal particles on the surface of the mask plate can be well adsorbed. The widest distance between any two points on the cross section of the fixing portion 21 is greater than or equal to 0.8 mm, so that the fixing portion 21 can support the bending portion 22 when the widest distance between any two points on the cross section of the bending portion 22 is 0.5 mm to 0.65 mm.
It is to be noted that, in the present embodiment, the sectional shape of the fixing portion 21 may be the same as that of the bending portion 22 in the direction perpendicular to the length direction of the pickup 2, thereby facilitating the preparation. The cross-sectional shape of the fixing portion 21 may be different from the cross-sectional shape of the bent portion 22, and the cross-sectional shape of the fixing portion 21 in the present embodiment may be circular, elliptical, square, or square with four corners curved, and the cross-sectional shape of the fixing portion 21 in the present embodiment is not limited.
The length of the fixed portion 21 is in the range of 5 cm to 6 cm, and the length of the bent portion 22 is 0.4 cm or less. In the scheme, the length of the bending part 22 is set to be less than 0.4 cm, so that the situation that the tail end of the bending part 22, which is far away from the fixing part 21, is drooped to scratch the surface of the mask plate due to the overlong bending part 22 is avoided. And the length range of the fixing part 21 is 5 cm-6 cm, so that the fixing part 21 can play a good supporting role on the bending part 22.
