Description

Technical Field

[0001] The present application relates to the technical field of material retrieving devices, and in particular to a material retrieving mechanism. Background Art

[0002] Currently, when using a gripper, support claw, or other retrieving mechanism to remove material from a carrier such as a tray, the mechanism is typically moved to a fixed height to retrieve the material. However, trays and other carriers are prone to deformation during use. When deformation lowers the material's loading height, the contact area between the retrieving mechanism and the material decreases, making it prone to dropping the material during the retrieving process, resulting in poor retrieving stability. Furthermore, when deformation raises the material's loading height, the retrieving mechanism is prone to squeezing and damaging the material. Utility Model Content

[0003] In view of the above, it is necessary to propose a material taking mechanism to improve the stability of material taking and reduce the probability of material damage.

[0004] An embodiment of the present application provides a material picking mechanism, which includes a moving component and a material picking component. The material picking component includes a material picking drive and multiple material picking modules. The material picking drive is connected to the moving component, and multiple material picking modules are connected to the material picking drive so as to approach or move away from each other under the drive of the material picking drive. Each of the material picking modules includes a connecting member, a sliding member, a material picking member and a step adjustment member. The connecting member is connected to the material picking drive, and the sliding member can be slidably arranged on the connecting member. The material picking member and the step adjustment member are spaced apart on the sliding member and form a height difference. The material picking member is used to support or clamp the material, and the step adjustment member is used to limit the distance between the material picking member and the material.

[0005] The material taking mechanism of the embodiment of the present application is provided with a sliding member that can be slidably mounted on the connecting member, and the material taking member and the step adjustment member are spaced apart on the sliding member to form a height difference. When the material taking mechanism takes out the material from the supporting member, since the material taking member and the step adjustment member can be raised and lowered with the sliding member, and the height difference between the material taking member and the step adjustment member is fixed, the safe distance between the material taking member and the bottom of the material can be minimized during design. If the supporting member is deformed so that the material carrying height becomes smaller, the distance between the material taking member and the bottom of the material can still be maintained within a reasonable range, thereby ensuring the contact area between the material taking member and the surface of the material, effectively avoiding the occurrence of material falling, and thus improving the stability of the material taking. If the supporting member is deformed so that the material carrying height becomes larger, since the step adjustment member abuts against the supporting member, the material taking height of the material taking member will change with the movement of the sliding member and the step adjustment member, and the distance between the material taking member and the bottom of the material can still be maintained within a safe distance, thereby reducing the probability of the material being squeezed by the material taking member and damaged.

[0026] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1 The embodiment of the present application provides a material removal mechanism 100 for removing a material 500 from a carrier 400. The carrier 400 may be a material tray, a fixture, etc., and the material 500 may be a bottom shell, a frame, etc. of an electronic product such as a mobile phone or a tablet computer. For ease of understanding, the embodiment of the present application is described by taking the carrier 400 as a material tray and the material 500 as a bottom shell of a mobile phone as an example. Obviously, this is not a limitation of the embodiment of the present application.

[0028] See also Figure 1 、 Figure 2 and Figure 3 In this embodiment, the material picking mechanism 100 includes a material picking component 10 and a moving component 20.

[0029] The material picking assembly 10 includes a material picking drive 11 and a plurality of material picking modules 12. The material picking drive 11 is connected to the moving assembly 20 so as to move under the drive of the moving assembly 20. The plurality of material picking modules 12 are connected to the material picking drive 11 so as to move closer to or farther away from each other under the drive of the material picking drive 11. Each material picking module 12 includes a connecting member 121, a sliding member 122, a material picking member 123 and a step adjustment member 124. The connecting member 121 is connected to the material picking drive 11. The sliding member 122 is slidably arranged on the connecting member 121 so as to be liftable. The material picking member 123 and the step adjustment member 124 are spaced apart from the sliding member 122 and form a height difference. The material picking member 123 and the step adjustment member 124 extend respectively along the sliding direction of the sliding member 122. The material picking member 123 is used to support or clamp the material 500. The step adjustment member 124 is used to limit the distance between the material picking member 123 and the material 500.

[0030] Specifically, a carrying groove 410 is defined on the carrier 400, and the material 500 is carried in the carrying groove 410. When the retrieving mechanism 100 removes the material 500 from the carrier 400, the moving assembly 20 drives the retrieving assembly 10 toward the carrier 400. The step adjustment members 124 of the multiple retrieving modules 12 abut against the surface of the carrier 400 where the carrying groove 410 is defined. The retrieving members 123 of the multiple retrieving modules 12 extend into the carrying groove 410. Then, the retrieving drive member 11 drives the multiple retrieving modules 12 away from each other so that the multiple retrieving members 123 support the inner sidewall of the material 500. The moving assembly 20 drives the retrieving assembly 10 away from the carrier 400 to remove the material 500 from the carrier 400.

[0031] Since the material picking piece 123 and the step adjustment piece 124 can be raised and lowered with the sliding piece 122, and the height difference between the material picking piece 123 and the step adjustment piece 124 is fixed, the safety distance between the material picking piece 123 and the bottom of the material 500 can be minimized as much as possible during design. When the supporting piece 400 is deformed, the depth of the supporting groove 410 generally does not change. If the supporting piece 400 is deformed so that the supporting height of the material 500 becomes smaller, the depth of the material picking piece 123 extending into the supporting groove 410 can still be maintained within a reasonable range, that is, the distance between the material picking piece 123 and the bottom of the material 500 can still be maintained within a reasonable range, thereby ensuring the contact area between the material picking piece 123 and the surface of the material 500, effectively avoiding the occurrence of material falling, and thereby improving the stability of material picking. If the supporting member 400 is deformed so that the carrying height of the material 500 increases, since the step adjustment member 124 abuts against the surface of the carrying groove 410 of the supporting member 400, the material picking height of the material picking member 123 will change with the movement of the sliding member 122 and the step adjustment member 124. The distance between the material picking member 123 and the bottom of the material 500 can still be maintained within a safe distance, thereby reducing the probability of the material picking member 123 squeezing the material 500 and damaging the material 500.

[0032] In some other embodiments, a supporting platform (not shown) may be protruded from the supporting member 400 to support the material 500 , which is not specifically limited in the embodiment of the present application.

[0033] In some other embodiments, the material picking drive 11 can also drive multiple material picking modules 12 to approach each other so that multiple material picking parts 123 clamp the outer wall of the material 500, and the material picking mechanism 100 can also take the material 500 out of the carrier 400. This embodiment of the present application does not make specific limitations on this.

[0034] Please refer to Figure 4 and Figure 6 In this embodiment, the height difference a between the step adjustment member 124 and the material picking member 123 satisfies the following relationship: a=b-safety distance, where b is the distance between the bottom of the material 500 and the surface of the supporting member 400 where the supporting groove 410 is opened, and the range of the safety distance is 1mm-3mm.

[0035] See also Figure 3 、 Figure 4 and Figure 5In this embodiment, each picking module 12 further includes an elastic member 125, which can be a spring. The elastic member 125 extends along the sliding direction of the sliding member 122, and the two ends of the elastic member 125 are respectively connected to the connecting member 121 and the sliding member 122. By providing the elastic member 125, the picking height of the picking member 123 can be appropriately lowered when multiple picking members 123 are picking materials. If the supporting member 400 is deformed so that the carrying height of the material 500 becomes smaller, the elastic member 125 can drive the sliding member 122, the step adjustment member 124 and the picking member 123 to move so that the step adjustment member 124 is pressed against the supporting member 400. The distance between the picking member 123 and the bottom of the material 500 will remain unchanged, thereby further reducing the occurrence of material falling and improving the stability of the picking. In addition, by providing the elastic member 125, the sliding member 122, the step adjustment member 124 and the material picking member 123 can be quickly driven to reset after the step adjustment member 124 is separated from the supporting member 400, thereby facilitating the material picking mechanism 100 to perform the material picking operation again.

[0036] In this embodiment, the connecting member 121 has a slide rail 1211 extending in a vertical direction. The sliding member 122 includes a sliding seat 1221 and a mounting plate 1222. The sliding seat 1221 is slidably mounted on the slide rail 1211, and the mounting plate 1222 is connected to the sliding seat 1221. The ends of the elastic member 125 are respectively connected to the connecting member 121 and the mounting plate 1222. The material removal member 123 is mounted on the sliding seat 1221, and the step adjustment member 124 is mounted on the mounting plate 1222. The provision of the slide rail 1211 helps improve the accuracy of the sliding member 122 in driving the step adjustment member 124 and the material removal member 123 to move upward and downward.

[0037] In this embodiment, the material picking member 123 is movably disposed on the sliding member 122, a first adjustment hole 1232a is defined on the material picking member 123, and a first connecting hole 1221a is defined on the sliding member 122. Each material picking module 12 further includes a first adjusting member 126. The cross-sectional dimensions of the first adjusting hole 1232a are greater than the cross-sectional dimensions of the first adjusting member 126. The first adjusting member 126 passes through the first adjustment hole 1232a and the first connecting hole 1221a to connect the material picking member 123 and the sliding member 122. Specifically, the material picking member 123 is movably disposed on the sliding seat 1221, the first connecting hole 1221a is defined on the sliding seat 1221, the first adjusting hole 1232a may be a waist-shaped hole extending in the horizontal direction, the first connecting hole 1221a may be a threaded hole, and the first adjusting member 126 may be a bolt. When the distance between the plurality of picking members 123 needs to be adjusted, the first adjusting member 126 can be loosened and the picking member 123 can be moved, and then the first adjusting member 126 can be tightened to fix the picking member 123 and the sliding seat 1221. In this way, by setting the first adjusting member 126 through the first adjusting hole 1232a and the first connecting hole 1221a to connect the picking member 123 and the sliding member 122, the distance between the plurality of picking members 123 can be adjusted easily.

[0038] In some other embodiments, a first adjustment hole 1232a may be opened on the sliding member 122, and correspondingly, a first connecting hole 1221a may be opened on the material picking member 123. Then, the first adjustment member 126 may pass through the first adjustment hole 1232a and the first connecting hole 1221a to connect the material picking member 123 and the sliding member 122, and may also adjust the distance between multiple material picking members 123. The embodiments of the present application do not specifically limit this.

[0039] In this embodiment, the material removal member 123 includes a flexible portion 1231, which is used to abut against the material 500. Specifically, the flexible portion 1231 can be made of a flexible material such as urethane. By providing the flexible portion 1231 to abut against the material 500, the probability of the material removal member 123 scratching the material 500 can be effectively reduced.

[0040] In this embodiment, the material removal member 123 further includes an assembly portion 1232, which can be made of a rigid material. The first adjustment hole 1232a is provided on the assembly portion 1232, and the flexible portion 1231 is detachably connected to the assembly portion 1232. This facilitates replacement of the flexible portion 1231 if it is damaged.

[0041] In this embodiment, the step adjustment member 124 is movably provided on the sliding member 122, a second adjustment hole 1241 is provided on the step adjustment member 124, and a second connecting hole 1222a is provided on the sliding member 122. Each material taking module 12 also includes a second adjustment member 127. The cross-sectional dimensions of the second adjustment hole 1241 are greater than the cross-sectional dimensions of the second adjustment member 127. The second adjustment member 127 passes through the second adjustment hole 1241 and the second connecting hole 1222a to connect the step adjustment member 124 and the sliding member 122. Specifically, the step adjustment member 124 is movably provided on the mounting plate 1222, the second connecting hole 1222a is provided on the mounting plate 1222, the second adjustment hole 1241 can be a waist-shaped hole and extends in the vertical direction, the second connecting hole 1222a can be a threaded hole, and the second adjustment member 127 can be a bolt. When the height difference between the step adjustment member 124 and the material taking member 123 needs to be adjusted, the second adjustment member 127 can be loosened and the step adjustment member 124 can be moved, and then the second adjustment member 127 can be tightened to fix the step adjustment member 124 and the mounting plate 1222. In this way, by setting the second adjustment member 127 through the second adjustment hole 1241 and the second connecting hole 1222a to connect the step adjustment member 124 and the sliding member 122, it is convenient to adjust the height difference between the step adjustment member 124 and the material taking member 123.

[0042] In some other embodiments, a second adjustment hole 1241 may be opened on the sliding member 122, and correspondingly, a second connecting hole 1222a may be opened on the step adjustment member 124. The second adjustment member 127 may pass through the second adjustment hole 1241 and the second connecting hole 1222a to connect the step adjustment member 124 and the sliding member 122, and may also adjust the height difference between the step adjustment member 124 and the material picking member 123. The embodiments of the present application do not specifically limit this.

[0043] See also Figure 3 In this embodiment, the retrieving drive member 11 includes a main body 111 connected to the moving assembly 20 and multiple drive units 112 connected to the main body 111. The main body 111 drives the multiple drive units 112 to move, and multiple connecting members 121 are respectively connected to the multiple drive units 112. The retrieving assembly 10 also includes a stop module 13 provided on the main body 111. The stop module 13 is arranged opposite to any retrieving module 12 and is used to stop the corresponding retrieving module 12. Specifically, the material picking drive 11 can be a clamping cylinder, and the multiple driving parts 112 of the material picking drive 11 are linked to each other. When the material picking drive 11 drives the multiple material picking modules 12 away from each other through the multiple driving parts 112, the material picking module 12 stops the corresponding connecting parts 121 of the material picking module 12 to limit the distance between the multiple material picking modules 12, thereby effectively avoiding the material 500 being damaged by the material picking parts 123 of the multiple material picking modules 12 due to excessive opening distance.

[0044] In some other embodiments, there can be multiple stop modules 13, and the multiple stop modules 13 correspond one-to-one to the multiple material picking modules 12. When the material picking driving member 11 drives the multiple material picking modules 12 away from each other, the multiple stop modules 13 respectively stop the corresponding material picking modules 12. In this way, it can further effectively prevent the material picking parts 123 of the multiple material picking modules 12 from damaging the material 500 due to excessive opening distance. The embodiment of the present application does not make specific limitations on this.

[0045] In this embodiment, the stopper module 13 includes a fixing member 131 and a stopper 132. The fixing member 131 is connected to the main body 111 of the material retrieving drive member 11. The stopper 132 is disposed through the fixing member 131 and is disposed opposite the connecting member 121 of the corresponding material retrieving module 12. The stopper 132 can be a travel limit screw. When the material retrieving drive member 11 drives the multiple material retrieving modules 12 away from each other, the stopper 132 stops the connecting member 121 of the corresponding material retrieving module 12. In this way, the stopper module 13 has a simple structure, low cost, and is conducive to improving the accuracy of stopping the corresponding material retrieving module 12.

[0046] See also Figure 2 and Figure 3 In this embodiment, the material picking component 10 also includes a sensing member 14. The sensing member 14 can be a functional sensor such as a laser sensor that can sense the position of an object. The sensing member 14 is arranged on the fixing member 131 or the main body 111 of the material picking drive member 11. The sensing member 14 is used to sense the position of the material 500, thereby facilitating the material picking module 12 to take the material 500 out of the carrier 400.

[0047] Please refer again Figure 1 、 Figure 2 and Figure 3 In this embodiment, the moving assembly 20 includes a lifting drive member 21, which can be a telescopic cylinder. The material-retrieving drive member 11 is connected to the lifting drive member 21 so as to be lifted and lowered by the lifting drive member 21. This helps to improve the accuracy of the moving assembly 20 driving the material-retrieving assembly 10 to retrieve materials.

[0048] In this embodiment, the retrieving mechanism 100 further includes a support frame 30. There are multiple, correspondingly arranged, mobile assemblies 20 and retrieving assemblies 10. Multiple mobile assemblies 20 are spaced apart from the support frame 30. The retrieving drive 11 of each retrieving assembly 10 is connected to the lifting drive 21 of the corresponding mobile assembly 20. In this manner, the multiple retrieving assemblies 10 of the retrieving mechanism 100 can simultaneously retrieve multiple materials 500 from the carrier 400, thereby improving the retrieving efficiency of the retrieving mechanism 100.

[0049] In this embodiment, the material picking mechanism 100 may further include a transfer assembly (not shown), which may be a robotic arm or a three-coordinate mobile platform. The support frame 30 is connected to the transfer assembly, and the transfer assembly drives multiple mobile assemblies 20 and multiple material picking assemblies 10 to move to the top of the carrier 400 through the support frame 30 to pick up materials, thereby helping to improve the accuracy and efficiency of the material picking mechanism 100 in picking up materials.

[0050] In this embodiment, each moving assembly 20 further includes a variable-distance adjustment drive member 22, which can be a slide cylinder. The lifting drive member 21 is connected to the variable-distance adjustment drive member 22. The variable-distance adjustment drive member 22 is used to drive the corresponding lifting drive member 21 and the corresponding material picking assembly 10 to move, thereby adjusting the spacing between the multiple material picking assemblies 10. In this way, the spacing between the multiple material picking assemblies 10 can be adjusted accordingly according to the distance between the multiple bearing slots 410, thereby facilitating the improvement of the accuracy of the multiple material picking assemblies 10 in simultaneously removing multiple materials 500 from the bearing member 400 and improving the versatility of the material picking mechanism 100.

[0051] In this embodiment, each moving component 20 also includes a fixed seat 23 and a third adjusting member 24. The fixed seat 23 is movably provided on the variable distance adjustment drive member 22. The lifting drive member 21 is provided on the fixed seat 23 and is connected to the variable distance adjustment drive member 22 through the fixed seat 23. A third adjusting hole 231 is provided on the fixed seat 23. The third adjusting hole 231 can be a waist-shaped hole. The third adjusting member 24 can be a bolt. The third adjusting member 24 is connected to the variable distance adjustment drive member 22 through the third adjusting hole 231, so as to facilitate the adjustment of the position of the variable distance adjustment drive member 22 and the material picking component 10 relative to the variable distance adjustment drive member 22.

[0052] In this embodiment, the variable distance adjustment drive member 22 includes a base portion 221 connected to the support frame 30 and a power portion 222 connected to the base portion 221. The base portion 221 drives the power portion 222 to move. The lifting drive member 21 is connected to the power portion 222. Each moving assembly 20 also includes an abutment 25 and a limit module 26. The abutment 25 is provided on the power portion 222. The limit module 26 is provided on the base portion 221 and is arranged opposite to the abutment 25. The limit module 26 is used to stop the abutment 25 to limit the distance that the variable distance adjustment drive member 22 drives the corresponding material picking assembly 10 to move. In this way, when multiple variable distance adjustment drive members 22 adjust the spacing between multiple material picking assemblies 10, each limit module 26 respectively stops the corresponding abutment 25 to limit the movement distance of the corresponding material picking assembly 10, thereby facilitating improving the accuracy of multiple variable distance adjustment drive members 22 in adjusting the spacing between multiple material picking assemblies 10.

[0053] In some other embodiments, the abutment 25 may also be provided on the lifting drive member 21 or the fixed seat 23, and the limiting module 26 may also be provided on the support frame 30. As long as the limiting module 2 is arranged opposite to the abutment 25, the embodiment of the present application does not make any specific restrictions on this.

[0054] In this embodiment, the limiting module 26 includes a fixed plate 261 and a limiting member 262. The fixed plate 261 is arranged on the base portion 221. The limiting member 262 can be an oil pressure buffer. The limiting member 262 is arranged on the fixed plate 261 and is arranged opposite to the abutment 25. The limiting member 262 stops the corresponding abutment 25 when multiple variable distance adjustment driving members 22 adjust the distance between multiple material picking components 10.

[0055] In summary, the material picking mechanism 100 of the embodiment of the present application is configured such that the sliding member 122 is slidably arranged on the connecting member 121 so as to be liftable, and the material picking member 123 and the step adjustment member 124 are spaced apart from the sliding member 122 to form a height difference. When the material picking mechanism 100 takes out the material 500 from the supporting member 400, since the material picking member 123 and the step adjustment member 124 can be lifted and lowered along with the sliding member 122, and the height difference between the material picking member 123 and the step adjustment member 124 is fixed, the safety distance between the material picking member 123 and the bottom of the material 500 can be minimized during design. If the supporting member 400 is deformed so that the carrying height of the material 500 is reduced, the distance between the material picking member 123 and the bottom of the material 500 can still be maintained within a reasonable range, thereby ensuring the contact area between the material picking member 123 and the surface of the material 500, effectively avoiding the occurrence of material falling, and thereby improving the stability of the material picking. If the supporting member 400 is deformed so that the carrying height of the material 500 increases, since the step adjustment member 124 abuts against the supporting member 400, the material picking height of the material picking member 123 will change with the movement of the sliding member 122 and the step adjustment member 124. The distance between the material picking member 123 and the bottom of the material 500 can still be maintained within a safe distance, thereby reducing the chance of the material picking member 123 squeezing the material 500 and damaging the material 500.
