[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] See also Figure 1 and Figure 2 , the adsorption device provided in the embodiment of the present application is now described. The adsorption device provided in the embodiment of the present application includes an adsorption member 1 and a positioning member 2, the adsorption member 1 is provided with an adsorption surface 11 for abutting against the upper surface of the workpiece, the positioning member 2 is provided on one side of the adsorption surface 11, and the positioning member 2 is provided with a positioning surface 21 abutting against the side of the workpiece on the side close to the adsorption surface 11, the positioning surface 21 and the adsorption surface 11 form a limiting groove 12 for accommodating the workpiece, and an avoidance groove 13 is provided at the connection between the positioning surface 21 and the adsorption surface 11.

[0030] The workpiece in the embodiment of the present application may be a lens, or may be other workpieces that can be transferred by adsorption.

[0031] Since the embodiment of the present application is mainly used for adsorbing objects with flat surfaces such as lenses, the embodiment of the present application adopts a vacuum adsorption method. The adsorption surface 11 of the adsorbent 1 in the embodiment of the present application is provided with an adsorption hole for adsorbing the workpiece, and a pipe connected to the adsorption hole is provided inside the adsorbent 1, and the other end of the pipe is connected to an external vacuum device. Before adsorbing the workpiece, the external vacuum device performs a vacuum treatment on the pipeline to form a low-pressure area at the adsorption hole connected to the pipeline to facilitate the adsorption of the workpiece. When adsorbing the workpiece, the side of the workpiece abuts against the positioning surface 21 of the positioning member 2, and the adsorption device is moved toward the surface of the workpiece so that the adsorption surface 11 of the adsorbent 1 abuts against the workpiece, and the external vacuum device continues to vacuum the pipeline so that the workpiece is adsorbed on the adsorption surface 11 of the adsorbent 1. After the workpiece is firmly adsorbed, the external vacuum device stops the vacuum treatment, so that the inside of the pipeline of the adsorbent 1 maintains a low-pressure environment, and the workpiece is kept on the adsorption surface 11 of the adsorbent 1 until the workpiece is transported to the next processing station.

[0032] In addition, the adsorption member 1 can also adsorb the workpiece by magnetic attraction. The magnetic attraction method requires that the workpiece itself has magnetism or the workpiece is a metal part that can be adsorbed by magnetic attraction.

[0033] The positioning member 2 is a positioning block arranged on one side of the adsorption surface 11 . A side of the positioning member 2 away from the positioning surface 21 is provided with an avoidance slope, which can prevent the adsorption device from interfering with other devices when moving.

[0034] When the adsorption member 1 adsorbs the workpiece, the side edge of the workpiece abuts against the positioning surface 21 of the positioning member 2, thereby realizing the side positioning of the workpiece and improving the subsequent processing accuracy of the workpiece.

[0035] When processing the positioning member 2 and the adsorption member 1, burrs are likely to remain at the connection between the positioning surface 21 and the adsorption surface. If the processing is not thorough, protrusions are likely to remain. Those remaining burrs or protrusions will cause incomplete contact between the workpiece and the adsorption surface 11. After the workpiece is adsorbed, the external vacuum device stops the vacuum treatment, and the inside of the pipe of the adsorption member 1 will not be able to maintain a low-pressure environment, making the workpiece easy to fall during transportation. Alternatively, after the workpiece is adsorbed, the side of the workpiece cannot contact the positioning surface 21, resulting in the inability to position the workpiece, affecting the subsequent processing accuracy of the workpiece.

[0036] An avoidance groove 13 is provided at the connection between the positioning surface 21 and the adsorption surface 11. The avoidance groove 13 is a groove. When processing the avoidance groove 13, the remaining protrusions or burrs at the connection between the positioning surface 21 and the adsorption surface 11 during processing can be dug out to prevent affecting the adsorption of the workpiece by the adsorption component 1 or preventing affecting the positioning of the workpiece by the positioning component 2.

[0037] The avoidance groove 13 may be a conical or square groove.

[0038] Preferably, the avoidance groove 13 is an arc-shaped groove. Compared with a conical or square groove, an arc-shaped groove is easier to process.

[0039] The avoidance groove 13 is tangent to the adsorption surface 11 or the positioning surface 21. When machining the avoidance groove 13, the cutting device only needs to directly cut the avoidance groove 13 along the adsorption surface 11 or the positioning surface 21 when machining the adsorption surface 11 or the positioning surface 21, without re-calibrating the tool.

[0040] In order to prevent the cutting device from cutting the pipe in the adsorption component 1 when cutting the avoidance groove 13 , the avoidance groove 13 is preferably tangent to the adsorption surface 11 .

[0041] The width of the avoidance groove 13 is 0.15 mm to 0.25 mm.

[0042] When the avoidance groove 13 is tangent to the adsorption surface 11, if the width of the avoidance groove 13 is greater than 0.25 mm, it is possible that a thin workpiece such as a lens will be stuck in the avoidance groove 13, causing the workpiece to be unable to leave the adsorption device when it moves to the next processing station. If the width of the avoidance groove 13 is less than 0.15 mm, it is possible that the protrusions or burrs remaining at the connection between the positioning surface 21 and the adsorption surface 11 during processing cannot be completely removed.

[0043] Preferably, the width of the avoidance groove 13 is 0.2 mm.

[0044] With this groove width, the workpiece will not get stuck in the avoidance groove 13 , and at the same time, the protrusions or burrs remaining at the connection between the positioning surface 21 and the adsorption surface 11 during processing can be completely removed.

[0045] The groove depth of the avoidance groove 13 is 0.075 mm to 0.125 mm.

[0046] When the avoidance groove 13 is tangent to the adsorption surface 11, if the depth of the avoidance groove 13 is greater than 0.125 mm, the avoidance groove 13 will weaken the strength of the positioning member 2, and the positioning member 2 will interfere with other devices, which will easily cause the positioning member 2 to be knocked off. If the depth of the avoidance groove 13 is less than 0.075 mm, the burrs or protrusions left due to the incomplete processing of the avoidance groove 13 will affect the adsorption of the adsorption member 1 on the workpiece or affect the positioning of the positioning member 2 on the workpiece.

[0047] Preferably, the avoidance groove 13 has a depth of 0.1 mm.

[0048] At this groove depth, the avoidance groove 13 will neither weaken the strength of the positioning member 2 nor cause burrs or protrusions remaining from incomplete processing to affect the adsorption of the workpiece by the adsorption member 1 or the positioning of the workpiece by the positioning member 2.

[0049] The positioning surface 21 is perpendicular to the adsorption surface 11. If the angle formed between the positioning surface 21 and the adsorption surface 11 is an acute angle, the positioning surface 21 will affect the adsorption of the workpiece by the adsorption surface 11. If the angle formed between the positioning surface 21 and the adsorption surface 11 is an obtuse angle, it is difficult for the positioning surface 21 to abut against the side of the workpiece, and it is difficult to achieve the side positioning of the workpiece.

[0050] The positioning surface 21 is parallel to the length direction of the adsorbent 1. If the positioning surface 21 is not parallel to the adsorbent 1, it will affect the adsorption of the workpiece by the adsorbent surface 11. Therefore, the positioning surface 21 needs to be parallel to the length direction of the adsorbent 1.

[0051] An embodiment of the present application also provides a transport device, comprising the adsorption device in any of the embodiments described above.

[0052] Since the transport equipment of the embodiment of the present application includes the adsorption device in any of the above embodiments, it has the beneficial effects brought by the adsorption device in any of the above embodiments, which will not be elaborated here.

[0053] The transport device may further include an X-axis moving member and a Y-axis moving member moving in the horizontal direction and a Z-axis moving member moving in the vertical direction. The Y-axis moving member is connected to the X-axis moving member, the Z-axis moving member is connected to the Y-axis moving member, and the adsorption device is connected to the Z-axis moving member.

[0054] The X-axis moving part may include a rotating motor, a screw rod, a nut, a slider and a slide rail. The rotating motor is connected to the screw rod to drive the screw rod to rotate. The nut is threadedly connected to the screw rod. The slider is installed on the nut. The length direction of the slide rail is parallel to the length direction of the screw rod. The nut is slidably connected to the slide rail. The rotating motor rotates the screw rod to move the slider along the length direction of the screw rod. The Y-axis moving part and the Z-axis moving part may adopt the same structure as the X-axis moving part. The Y-axis moving part is installed on the slider of the X-axis moving part, the Z-axis moving part is installed on the slider of the Y-axis moving part, and the adsorption device is installed on the slider of the Z-axis moving part. The X-axis moving part and the Y-axis moving part can drive the adsorption device to move above the workpiece in the horizontal direction, and the Z-axis moving part can make the adsorption device approach or move away from the workpiece in the vertical direction.

[0055] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
