Description

Technical Field

[0001] This application relates to the field of product alignment technology, specifically to an alignment device. Background Technology

[0002] In the manufacturing process of precision products, guiding devices are generally used to guide and position components, such as guiding metal springs in mobile phones. The cylinder in the guiding device pushes the metal spring to a reference part to guide the metal's elasticity, making it easier to remove and process the guided metal spring. However, the metal spring is thin and has low bending stiffness, making it prone to deformation under the push of the cylinder, which reduces the guiding accuracy. Utility Model Content

[0003] In view of the above, it is necessary to propose a guiding device to improve the guiding accuracy.

[0004] One embodiment of this application provides a guiding device, which includes an adsorption member, a guiding member, and a driving member. The adsorption member has adsorption holes configured to adsorb small parts; the guiding member is sleeved on the adsorption member and has a communicating guiding groove and a positioning groove. In a first direction, the cross-sectional area of ​​the guiding groove gradually decreases along a second direction, and the positioning groove is used to position the small parts. The first direction is perpendicular to the second direction; the driving member is connected to the guiding member and is used to drive the guiding member to descend so that the adsorption member extends out of the guiding groove, and also to drive the guiding member to rise so that the small parts move under the guidance of the guiding groove to the positioning groove.

[0005] In use, the aforementioned guiding device works as follows: First, the driving component lowers the guiding component, causing the adsorption component to extend out of the guiding groove. Then, the small part is placed on the adsorption component, and the adsorption holes adsorb the small part located on the adsorption component, avoiding rigid contact with the small part. Finally, the driving component raises the guiding component, causing the adsorption component to flexibly slide the small part within the guiding groove, so that the groove wall pushes against the side wall of the small part, guiding the small part to a preset orientation. The adsorption component then moves the guided small part to the positioning groove, where the positioning groove positions the small part. The guiding device, by driving the guiding component to rise, causes the adsorption component to flexibly slide the adsorbed small part within the guiding groove, gradually guiding the small part to a preset orientation. This avoids rigidly guiding the small part in a short time, which could cause deformation, thus improving the guiding accuracy. It can be used for various irregularly shaped spring piece detection, positioning, and assembly technologies.

[0006] In some embodiments, the adsorption element includes an adsorption body and a support body; the adsorption body is movably disposed in the positioning groove and the guiding groove, and the adsorption hole is disposed in the adsorption body, the sum of the length of the guiding groove and the length of the positioning groove is less than the length of the adsorption body; the support body is connected to the adsorption body, the support body is connected to the adsorption hole, and the support body is used to support the guiding element.

[0007] In some embodiments, the guide includes a guide body and a connector; the guide body is sleeved on the adsorbent, and a guide groove and a positioning groove are provided on the guide body; one end of the connector is connected to the guide body, and the other end of the connector is connected to the drive member; the connector is located above the support body, and the connector is provided with a through groove that passes through the connector in the direction from the guide body to the connector, and the through groove is used for the adsorbent to be inserted.

[0008] In some embodiments, the connector has a flexible portion on the side facing the support, and the flexible portion is configured to abut against the support.

[0009] In some embodiments, the connector includes a connecting portion and a locking portion. The connecting portion is connected to the drive member, and the locking portion is movably inserted through the connecting portion and the guide body in the direction from the adsorbent body to the support body and is threadedly connected to the guide body.

[0010] In some embodiments, the end of the adsorbent away from the support has a bearing plane, which is used to support small parts.

[0011] In some embodiments, the guiding device further includes a control valve, which is connected to the adsorption orifice and the gas source respectively, and is used to control the adsorption state of the adsorption orifice.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular implementations only and is not intended to limit the application.

[0020] Please see Figure 1 One embodiment of this application provides a guiding device 100, which can quickly and accurately guide a small part, improving the guiding accuracy. In some embodiments, the small part can be a metal spring. It is understood that in other embodiments, the small part can also be an object of other shapes or other structures, and this application embodiment does not specifically limit it in this regard.

[0021] For ease of understanding and explanation, the embodiments of this application define the XYZ coordinate system as shown in the figure, where the X-axis is the first direction, the Z-axis is the second direction, and the Y-axis is the third direction. Obviously, this is not a limitation on the embodiments of this application.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The guiding device 100 includes an adsorption member 10, a guiding member 20, and a driving member 30. The adsorption member 10 has adsorption holes 11 configured to adsorb small parts. The guiding member 20 is sleeved on the adsorption member 10 and has a communicating guiding groove 21 and a positioning groove 22. In a first direction, the cross-sectional area of ​​the guiding groove 21 gradually decreases along a second direction, and the positioning groove 22 is used to position the small parts. The driving member 30 is connected to the guiding member 20. The driving member 30 is used to drive the guiding member 20 downwards so that the adsorption member 10 extends out of the guiding groove 21, and also to drive the guiding member 20 upwards so that the small parts move under the guidance of the guiding groove 21 to the positioning groove 22. The driving member 30 can be a cylinder, a servo slide, etc.

[0023] When the above-mentioned guiding device 100 is in use, firstly, the driving member 30 drives the guiding member 20 to descend, so that the adsorption member 10 extends out of the guiding groove 21; then, the small part is placed on the adsorption member 10, and the adsorption hole 11 adsorbs the small part located on the adsorption member 10, avoiding rigid contact with the small part; finally, the driving member 30 drives the guiding member 20 to rise, so that the adsorption member 10 drives the small part to slide flexibly in the guiding groove 21, so that the groove wall of the guiding groove 21 pushes against the side wall of the small part to guide the small part to a preset orientation, and the adsorption member 10 then drives the guided small part to move to the positioning groove 22, so that the positioning groove 22 positions the small part. The guiding device 100 drives the guiding component 20 to rise through the driving component 30, so that the adsorption component 10 drives the adsorbed small part to slide flexibly in the guiding groove 21 and the guiding groove 21, so that the guiding groove 21 gradually guides the small part to the preset orientation, avoiding the situation where the small part is deformed due to rigid guiding in a short time, thereby improving the guiding accuracy. It can be used for various irregularly shaped spring piece detection, positioning and assembly technologies.

[0024] It is understandable that the cross-sectional area of ​​the guide groove 21 gradually decreases along the second direction, which enables the small part to be gradually guided by the push of the groove wall of the guide groove 21.

[0025] Please see Figure 2 and Figure 3 In some embodiments, the adsorption element 10 includes an adsorption body 12 and a support body 13. The adsorption body 12 is movably disposed through the positioning groove 22 and the guide groove 21, and an adsorption hole 11 is disposed in the adsorption body 12. The sum of the length of the guide groove 21 and the length of the positioning groove 22 is less than the length of the adsorption body 12. The support body 13 is connected to the adsorption body 12 and communicates with the adsorption hole 11. The support body 13 is used to support the guide element 20. By setting the sum of the lengths of the guide groove 21 and the positioning groove 22 to be less than the length of the adsorbent 12, when the driving member 30 drives the guide member 20 to descend, the adsorbent 12 can extend out of the guide groove 21. This facilitates the placement of small parts to be guided onto the adsorbent 12, preventing the guide member 20 from interfering with the placement of small parts if the adsorbent 12 does not extend out of the guide groove 21. This also helps the adsorbent 10 adsorb small parts, thereby improving the stability of material feeding. In addition, when the driving member 30 drives the guide member 20 to descend, the support 13 can support the guide member 20 to limit the distance the guide member 20 moves close to the support 13, preventing the adsorbent 10 from detaching from the guide member 20. This also helps the guide member 20 quickly guide small parts when it rises.

[0026] Please see Figure 2 and Figure 3In some embodiments, the guide 20 includes a guide body 23 and a connector 24. The guide body 23 is sleeved on the adsorption body 12, and a guide groove 21 and a positioning groove 22 are provided on the guide body 23. One end of the connector 24 is connected to the guide body 23, and the other end of the connector 24 is connected to the drive member 30. The connector 24 is located above the support body 13, and the connector 24 is provided with a through groove 241. The through groove 241 penetrates the connector 24 in the direction from the guide body 23 to the connector 24, and the through groove 241 is used for the adsorption body 12 to be inserted. By setting the connector 24 to be connected to the drive member 30 and the guide body 23 respectively, the placement space of the guide device 100 can be reasonably utilized, the structural layout of the guide 20 and the adsorption body 10 can be optimized, which is conducive to the miniaturization of the guide device 100 and facilitates the application of the guide device 100 in narrow working spaces.

[0027] Please see Figure 3 In some embodiments, the connecting body 24 has a flexible portion 242 on the side facing the support body 13, and the flexible portion 242 is configured to abut against the support body 13. When the driving member 30 drives the connecting body 24 to lower the guide body 23, the connecting body 24 abuts against the support body 13 through the flexible portion 242, so that a flexible contact is formed between the guide body 20 and the support body 13, preventing rigid collision between the guide body 20 and the support body 13 that would cause the guiding device 100 to shake or shift, thereby ensuring the operational stability of the guiding device 100. The flexible portion 242 can be made of materials such as urethane or silicone.

[0028] Please see Figure 3 In some embodiments, the connector 24 includes a connecting portion 243 and a locking portion 244. The connecting portion 243 is connected to the drive member 30, and the locking portion 244 is movably inserted through the connecting portion 243 and the guide body 23 in the direction from the adsorbent 12 to the support body 13, and is threadedly connected to the guide body 23. By providing the locking portion 244 movably inserted through the connecting portion 243 and the guide body 23, and threadedly connected to the guide body 23, a split structure can be formed between the connector 24 and the guide body 23, facilitating the disassembly and assembly of the guide device 100. The locking portion 244 can be a bolt.

[0029] Please see Figure 3 In some embodiments, the end of the adsorbent 12 away from the support 13 has a bearing plane 121, which is used to support the small part. The adsorbent 12 can make contact with the plane of the small part through the bearing plane 121, avoiding gaps between the small part and the adsorbent 12, so that the adsorbent 12 is in close contact with the lower surface of the small part, thereby enabling the adsorbent 12 to stably support and adsorb the small part, thereby improving the support stability and adsorption accuracy.

[0030] Please see Figure 1 and Figure 2In some embodiments, the guiding device 100 further includes a control valve 40, which is connected to the adsorption hole 11 and the air source respectively. The control valve 40 is used to control the adsorption state of the adsorption hole 11. By setting the control valve 40 to be connected to the adsorption hole 11 and the air source respectively, the control valve 40 can quickly control the adsorption hole 11 to switch the adsorption state according to the loading and unloading operation. This allows the adsorption hole 11 to generate negative pressure to adsorb small parts when loading them, and to switch to positive pressure to release small parts when loading small parts. This facilitates the rapid handling of small parts and improves work efficiency. In addition, the control valve 40 can adjust the negative pressure of the adsorption hole 11 to control the suction force applied to the small parts, so that the adsorbent 12 can stably adsorb the small parts, while avoiding deformation of the small parts due to excessive suction force. The control valve 40 can be a vacuum control valve 40.

[0031] In some embodiments, the wall of the guide groove 21 and the wall of the positioning groove 22 are connected by an arc transition. By setting the arc transition connection between the wall of the guide groove 21 and the wall of the positioning groove 22, the small part can be smoothly moved from the guide groove 21 to the positioning groove 22, preventing the small part from shaking or shifting during the process of moving from the guide groove 21 to the positioning groove 22 after being guided, thereby improving the guidance accuracy.

[0032] Please see Figure 2 In some embodiments, the end of the guide groove 21 away from the positioning groove 22 is provided with a chamfered portion 211. When the small part moves into the guide groove 21, the chamfered portion 211 can avoid the small part, preventing the small part from colliding with the guide member 20, so that the small part can move smoothly into the guide groove 21, thereby improving the guiding stability.

[0033] In some embodiments, the adsorption member 10, the guide groove 21, and the positioning groove 22 are coaxially arranged. By coaxially arranging the adsorption member 10, the guide groove 21, and the positioning groove 22, the movement direction of the adsorption member 10 can always be parallel to the direction of the guide groove 21 pointing to the positioning groove 22, ensuring that the guide groove 21 accurately guides the small part, thereby improving the guidance accuracy.

[0034] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
