Description

Technical Field

[0001] This utility model relates to the field of lens assembly technology, and in particular to a pen suction tip and a pen suction device. Background Technology

[0002] A lens typically consists of a lens barrel and multiple lens elements, gaskets, spacers, and other components installed inside the lens barrel. During the testing phase before mass production, workers typically use a handheld pen to install the lens elements, gaskets, spacers, and other components inside the lens barrel, and then test the assembled lens for various performance characteristics.

[0003] Traditional magnetic pens have suction points whose suction surface size is specifically designed for the size of the parts to be suctioned. As a result, the magnetic pen needs to be changed frequently during lens assembly, making the lens assembly process cumbersome and inefficient, which to some extent affects the efficiency of lens performance testing.

[0004] Therefore, there is an urgent need to propose a pen-absorbing tip and a pen-absorbing device to solve the above-mentioned technical problems. Utility Model Content

[0005] According to one aspect of this utility model, a pen suction tip is provided, which is applicable to parts of different sizes, has high versatility, and improves the assembly efficiency of lenses.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A pen tip includes a pen tip body, the pen tip body having a first end and a second end disposed opposite to each other, and the pen tip body having an adsorption hole penetrating the first end and the second end;

[0008] The first end is provided with at least two adsorption sections, each of which is used to adsorb a component. Along the axial direction of the pen tip body, the at least two adsorption sections are stacked in a stepped manner, and the diameter of the at least two adsorption sections decreases sequentially away from the second end along the axial direction of the pen tip body.

[0009] Optionally, the adsorption section includes an annular adsorption surface, which is a plane or an arc surface.

[0010] Optionally, the width of the annular adsorption surface is 0.3mm-0.4mm.

[0011] Optionally, the outer peripheral wall of the second end is provided with external threads, and the pen tip body is connected to the pen barrel through the external threads.

[0012] Optionally, the pen tip is a one-piece structure.

[0013] Optionally, the adsorption section has three layers.

[0014] Optionally, the material of the pen tip is polyetheretherketone (PEEK).

[0015] According to another aspect of the present invention, the present invention also provides a suction pen, comprising an air tube, a pen holder, and a suction pen head as described in any of the above technical solutions, wherein one end of the air tube is connected to a suction source, the other end of the air tube is connected to one end of the pen holder, and the other end of the pen holder is detachably connected to the second end of the suction pen head.

[0016] Optionally, the pen holder has a gripping part on its outer peripheral wall.

[0017] Optionally, the grip portion is provided with an anti-slip structure.

[0018] The beneficial effects of this utility model are:

[0019] This invention provides a suction pen tip, comprising a pen tip body, which includes a first end and a second end disposed opposite to each other. The pen tip body has a suction hole penetrating through the first and second ends. The first end has at least two layers of suction portions, each layer for adsorbing one type of component. By providing at least two layers of suction portions for adsorbing components, this suction pen tip can be used to adsorb at least two different sizes of components. That is, using this suction pen tip, at least two components can be assembled. Compared with existing technologies where each suction pen tip can only adsorb one specific size of component, this invention, on the one hand, eliminates the need for frequent replacement of suction pen tips during lens assembly, improving lens assembly efficiency and thus, to some extent, improving lens performance testing efficiency; on the other hand, it has higher versatility, which helps to reduce equipment costs.

[0020] Furthermore, along the axial direction of the pen tip body away from the second end, the diameters of at least two adsorption layers decrease sequentially. This arrangement results in at least two adsorption layers forming a gradually decreasing diameter protrusion structure at the second end of the pen tip body. This avoids interference between the adsorption layer adjacent to the adsorption layer and the tray holding the parts when using one adsorption layer to adsorb a part, thus reducing the difficulty of picking up the parts.

[0021] This invention also provides a suction pen, including an air tube, a pen holder, and the aforementioned suction pen head. Because of the suction pen head, this suction pen can assemble multiple components at once, improving lens assembly efficiency. Attached Figure Description

[0037] Traditional magnetic pens have suction points whose suction surface size is specifically designed for the size of the parts to be suctioned. As a result, the magnetic pen needs to be changed frequently during lens assembly, making the lens assembly process cumbersome and inefficient, which to some extent affects the efficiency of lens performance testing.

[0038] To address the aforementioned issues, this embodiment provides a pen suction tip that is applicable to components of different sizes, exhibiting high versatility and improving lens assembly efficiency.

[0039] Specifically, such as Figures 1-4 As shown, the pen tip 100 includes a pen tip body 110, which has a first end and a second end disposed opposite to each other. An adsorption hole 120 is provided inside the pen tip body 110, penetrating the first end and the second end. A suction source draws air through the adsorption hole 120, enabling the pen tip body 110 to adsorb components. At least two adsorption layers are provided at the first end of the pen tip body 110, each layer adsorbing a specific component. Along the axial direction of the pen tip body 110, the at least two adsorption layers are stacked in a stepped manner. Furthermore, along the axial direction of the pen tip body 110 away from the second end, the diameter of the at least two adsorption layers decreases sequentially.

[0040] Optionally, see [link to relevant documentation] Figure 1 In this embodiment, the adsorption section has three layers, which are close to the pen tip body 110 along the axial direction of the pen tip body 110. The three adsorption sections are, in sequence, a first adsorption section 131, a second adsorption section 132, and a third adsorption section 133. The first adsorption section 131, the second adsorption section 132, and the third adsorption section 133 can respectively realize the assembly of three different components.

[0041] To facilitate understanding, the working process of the pen tip 100, which has a first adsorption part 131, a second adsorption part 132, and a third adsorption part 133, is briefly introduced using the assembly of a first lens 20, a second lens 30, and a third lens 40 as an example:

[0042] First, such as Figure 2 As shown, the first suction part 131 is used to pick up a first lens 20 from the tray, and then the suction pen head 100 is moved to insert the suction pen head 100 into the lens barrel 10 until the first lens 20 is placed in place. Then the suction source is turned off to separate the suction pen head 100 from the first lens 20 and the suction pen head 100 is removed.

[0043] Then, as Figure 3As shown, the second suction part 132 is used to pick up a second lens 30 from the tray, and then the suction head 100 is moved to insert the suction head 100 into the lens until the second lens 30 is in place. Then the suction source is turned off to separate the suction head 100 from the second lens 30 and the suction head 100 is removed. It can be understood that the second lens 30 is placed above the first lens 20.

[0044] Finally, as Figure 4 As shown, the third suction unit 133 is used to pick up a third lens 40 from the tray, and then the suction head 100 is moved to insert the suction head 100 into the lens until the third lens 40 is in place. Then the suction source is turned off to separate the suction head 100 from the third lens 40 and the suction head 100 is removed. It can be understood that the third lens 40 is placed above the second lens 30.

[0045] That is, the suction head 100 provided in this embodiment can assemble several different parts by setting several layers of suction parts. Compared with the prior art where each suction head 100 can only adsorb one type of part of a specific size, on the one hand, it eliminates the need to frequently change the suction head 100 during lens assembly, improving lens assembly efficiency and thus improving lens performance testing efficiency to a certain extent; on the other hand, it has high versatility, which helps reduce equipment costs. Furthermore, by setting at least two layers of suction parts with progressively decreasing diameters away from the second end along the axial direction of the pen head body 110, the at least two layers of suction parts form a gradually decreasing diameter protrusion structure at the second end of the pen head body 110. This allows the other suction parts to avoid the tray when one suction part is used to adsorb a part. For example, as shown in the example... Figure 2 As shown, when the first adsorption part 131 is used to pick up the first lens 20 from the tray, the second adsorption part 132 and the third adsorption part 133 will not come into contact with the tray, reducing the difficulty of picking up the parts. Figure 3 As shown, when the second adsorption part 132 is used to pick up the second lens 30 from the tray, the first adsorption part 131 and the third adsorption part 133 will not come into contact with the tray.

[0046] It is worth noting that in other embodiments, the number of adsorption layers can be less than three or more than three, such as two or four layers, depending on actual needs.

[0047] It is understood that, in this embodiment, when using the second adsorption part 132 or the third adsorption part 133 to adsorb components, the components should have a recessed feature to avoid the first adsorption part 131; this is not applicable to components without a corresponding recessed feature. Furthermore, with Figure 3Taking the illustrated scheme as an example, when assembling the second lens 30 using the second adsorption part 132, the distance between the first adsorption part 131 and the second lens 30 should be greater than or equal to 0.05 mm to prevent the first adsorption part 131 and the second lens 30 from contacting each other and causing mutual wear. Similarly, the distance between the third adsorption part 133 and the limiting surface for installing the next component inside the lens barrel 10 should also be greater than or equal to 0.05 mm.

[0048] Furthermore, the adsorption section includes an annular adsorption surface. When using the suction tip 100 to adsorb parts, the annular adsorption surface adheres to the parts, forming a closed gas channel between the suction tip 100 and the parts, thus successfully adsorbing the parts. Optionally, depending on the shape of the parts' surface, the annular adsorption surface can be set as a plane or as a curved surface.

[0049] Optionally, to ensure reliable adsorption between the pen tip 100 and the component, the width of the annular adsorption surface can be 0.3mm-0.4mm, for example, it can be 0.32mm, 0.34mm, 0.36mm, 0.38mm or 0.4mm, etc. The specific width depends on the diameter of the lens barrel 10 and the structural design of the component.

[0050] Understandably, the diameter of the adsorption hole 120 can be set according to the size of the suction pen tip 100 and the structure of the parts to be adsorbed, so as to ensure reliable adsorption.

[0051] Optionally, see [link to relevant documentation] Figure 1 An external thread 140 is provided on the outer peripheral wall of the second end of the pen tip body 110, and the pen tip body 110 is connected to the pen holder through the external thread 140. When assembling the lens, the operator holds the pen holder to operate, and the assembly difficulty is low. The connection between the pen tip 100 and the pen holder is achieved through a threaded connection, which is simple in structure and convenient for installation and disassembly; on the other hand, it is convenient to replace the appropriate pen tip 100 according to different lens models.

[0052] Furthermore, the pen tip 100 is a one-piece structure, which provides high structural stability and facilitates processing.

[0053] Alternatively, the pen tip 100 can be made of polyetheretherketone (PEEK). This material is inexpensive and does not easily scratch the parts.

[0054] This embodiment also provides a suction pen, including an air tube, a pen holder, and the suction pen head 100 described above. One end of the air tube is used to communicate with a suction source, and the other end of the air tube is connected to one end of the pen holder. The other end of the pen holder is detachably connected to the second end of the suction pen head 100.

[0055] When using this suction pen to assemble a lens, hold the pen holder and move the suction pen head 100. By opening and closing the air tube, the suction pen head 100 can be used to adhere to and separate from the parts.

[0056] Because of the aforementioned suction pen head 100, this suction pen can assemble multiple parts at once, improving the assembly efficiency of the lens.

[0057] Furthermore, a grip is provided on the outer peripheral wall of the pen holder. By providing a grip, the staff can easily hold the pen holder, improving the convenience of operating the pen.

[0058] Optionally, an anti-slip structure can be provided on the grip to improve the reliability of the pen holder for the staff and reduce the risk of damage to parts due to the pen falling off.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
