Description

Technical Field

[0001] This utility model relates to material transfer equipment, and more particularly to a material transfer device. Background Technology

[0002] In modern product processing, such as grinding, a transfer plate is typically used to load multiple products into a support fixture. These products are then inserted into multiple clamping holes in the fixture, with each hole interlocking with the corresponding product to hold and secure it. After processing, the products are unloaded from the support fixture onto the transfer plate. However, because liquids and debris easily adhere to the transfer plate and support fixture during processing, transferring products between them can be difficult. Therefore, operators must use a top plate to drive multiple ejector pins to push the products together, completing the loading and unloading process.

[0003] However, when the ejector pin pushes against the product, it forms a hard contact with the product, and the force applied to the top plate by the operator is difficult to control, which can easily damage the product and reduce its quality. At the same time, manual material handling is labor-intensive and reduces material handling efficiency. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a material transfer device to improve the product quality and material transfer efficiency of the workpiece.

[0005] This application provides a material transfer device, including: A clamping assembly includes a carrier, a linkage, an elastic element, a rotating element, and multiple clamping components. One side of the carrier has a receiving groove, and the other side has multiple bearing positions and multiple through slots. Each bearing position corresponds to one of the through slots, and each bearing position is configured to bear a workpiece. The through slots penetrate the carrier and communicate with the receiving groove, and are configured to allow partial insertion of the workpiece. The linkage is slidably disposed in the receiving groove along a first direction and has multiple communicating slots, each corresponding to one of the through slots. The two ends of the elastic element elastically abut against the walls of the linkage and the receiving groove, respectively. The rotating member is movably inserted through the bearing member along the first direction and movably connected to the linkage member. The rotating member abuts against the side wall of the bearing member. The rotating member is configured to rotate relative to the bearing member so that the linkage member moves along the first direction under the drive of the rotating member and compresses the elastic member to the groove wall of the receiving groove. A plurality of clamping members correspond one-to-one with a plurality of through grooves. The clamping members are movably inserted through the corresponding through grooves along a second direction perpendicular to the first direction and connected to the linkage member. The clamping members are used to clamp the workpiece under the drive of the linkage member and release the workpiece under the push of the elastic member. A transfer assembly is movably disposed on the side of the support member opposite to the linkage member, and has multiple transfer positions and multiple through slots. The multiple transfer positions are evenly arranged on the transfer assembly and correspond one-to-one with the multiple support positions and the multiple through slots. Each transfer position is configured to support the workpiece, and each through slot penetrates the transfer assembly. The ejector assembly is used to place on the side of the transfer assembly away from the carrier during loading and to deliver gas to the plurality of through slots to transfer the workpiece located at the transfer position to the corresponding carrier position. It is also used to place on the side of the carrier away from the transfer assembly during unloading and to deliver gas to the receiving slot to transfer the workpiece located at the carrier position to the corresponding transfer position.

[0006] When the aforementioned material transfer device is loading material, firstly, the clamping component is positioned above and on the transfer component so that the workpiece at the transfer position corresponds to the corresponding bearing position; then, the clamping component and the transfer component are flipped together, and the ejector component is placed on the side of the transfer component away from the bearing member and gas is supplied to multiple through slots so that the workpiece falls into the corresponding bearing position under the combined action of gas and gravity; finally, the rotating component rotates relative to the bearing member along the preset direction and abuts against the side wall of the bearing member so as to drive the linkage component to compress the elastic component to the groove wall of the receiving slot, so that multiple clamping components clamp the corresponding workpiece to the groove wall of the through slot; When the material transfer device is unloading, firstly, the transfer component is placed above the clamping component and on the clamping component so that the workpiece on the bearing position corresponds to the corresponding transfer position; then, the clamping component and the transfer component are flipped together, and the workpiece is placed on the side of the bearing component away from the transfer component; finally, the rotating component rotates relative to the bearing component in the opposite direction to the preset direction and abuts against the side wall of the bearing component, so as to drive the linkage component to move away from the elastic component, so that multiple clamping components are released from the corresponding workpieces. At the same time, the ejector component delivers gas to the receiving groove, so that the gas blows towards the workpiece through the connecting groove and the through groove, so that the workpiece falls into the corresponding transfer position under the combined action of gas and gravity.

[0007] Thus, in the material transfer device, the ejector component is placed on the side of the transfer component away from the carrier during loading and supplies gas to multiple through slots to quickly and stably transfer the workpiece located at the transfer position to the corresponding carrier position. During unloading, the ejector component is placed on the side of the carrier component away from the transfer component and supplies gas to the receiving slot to quickly and stably transfer the workpiece located at the carrier position to the corresponding transfer position. This achieves flexible loading and unloading of workpieces through the combined action of gas and gravity, preventing the workpieces from being damaged by hard pushing during loading and unloading operations, thereby improving the product quality of the workpieces. At the same time, manual loading and unloading operations are not required, thus improving the material transfer efficiency.

[0008] In some embodiments, the ejection component includes: An air blowing component is configured to be placed on the side of the transfer assembly away from the carrier during loading and on the side of the carrier away from the transfer assembly during unloading. The air blowing component is provided with an air inlet groove and multiple air outlet grooves. The multiple air outlet grooves correspond one-to-one with the multiple connecting grooves and the multiple through grooves. Each air outlet groove is connected to the air inlet groove. A connecting element is connected to the air inlet slot and an external air source respectively. The connecting element is configured to deliver the gas to the plurality of air outlet slots through the air inlet slot under the conduction of the external air source.

[0009] In some embodiments, the ejection component further includes: A sealing element is disposed around the plurality of the air outlet slots and connected to the air blowing element, the sealing element being used to abut against the carrier to seal the connection between the carrier and the air blowing element.

[0012] In some embodiments, the rotating member includes: The movable body is movably inserted through the bearing member along the first direction; A first rotating shaft is movably inserted through the movable body and the linkage member along the second direction, and is rotatably connected to the movable body and the linkage member respectively; The second rotating shaft is movably disposed along the second direction at the end of the movable body away from the linkage member; and A rotating body is disposed on one side of the bearing member and rotatably connected to the second rotating shaft. The side wall of the rotating body is provided with a locking surface and a releasing surface connected to each other. The distance between the locking surface and the second rotating shaft is greater than the distance between the releasing surface and the second rotating shaft. The locking surface is configured to abut against the side wall of the bearing member to drive the movable body to move the linkage closer to the elastic member. The releasing surface is configured to abut against the side wall of the bearing member to drive the movable body to move the linkage away from the elastic member.

[0013] In some embodiments, the linkage member has a storage groove on the side facing the rotating member, and the storage groove is configured to store part of the elastic member.

[0014] In some embodiments, the end of the clamping member away from the linkage member is provided with a flexible body, which is used to flexibly clamp the workpiece.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0027] Please see Figure 1 This application provides a material transfer device 100, which includes a clamping assembly 10, a material transfer assembly 20, and an ejection assembly 30.

[0028] To facilitate understanding and explanation of the embodiments of this application, a three-dimensional coordinate system has been established in some of the accompanying drawings, with the first direction being... Figure 1 The X-axis direction is shown, and the second direction is... Figure 1 The Z-axis direction shown is the third direction. Figure 1 The Y-axis direction shown is perpendicular to each other in the first, second, and third directions.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The clamping assembly 10 includes a carrier 11, a linkage 12, an elastic member 13, a rotating member 14, and multiple clamping members 15. One side of the carrier 11 has a receiving groove 111, and the other side has multiple bearing positions 112 and multiple through grooves 113. Each bearing position 112 corresponds to one through groove 113, and each bearing position 112 is configured to bear a workpiece. The through grooves 113 penetrate the carrier 11 and communicate with the receiving groove 111, and are configured to allow partial workpiece insertion. The linkage 12 slides along a first direction in the receiving groove 111 and has multiple communicating grooves 121, each corresponding to one through groove 113. The two ends of the elastic member 13 elastically abut against the walls of the linkage 12 and the receiving groove 111, respectively. A rotating member 14 is movably inserted through the bearing member 11 along a first direction and movably connected to the linkage member 12. The rotating member 14 abuts against the side wall of the bearing member 11. The rotating member 14 is configured to rotate relative to the bearing member 11, so that the linkage member 12 moves along the first direction under the drive of the rotating member 14 and compresses the elastic member 13 to the groove wall of the receiving groove 111. A plurality of clamping members 15 correspond one-to-one with a plurality of through grooves 113. The clamping members 15 are movably inserted through the corresponding through grooves 113 along a second direction and connected to the linkage member 12. The clamping members 15 are used to clamp the workpiece under the drive of the linkage member 12 and release the workpiece under the push of the elastic member 13. The transfer assembly 20 is movably disposed on the side of the carrier 11 opposite to the linkage 12, and is provided with multiple transfer positions 21 and multiple through slots 22. The multiple transfer positions 21 are evenly arranged in the transfer assembly 20 and correspond one-to-one with the multiple carrier positions 112 and the multiple through slots 22. The transfer positions 21 are configured to carry workpieces, and each through slot 22 passes through the transfer assembly 20. The ejection assembly 30 is used to place on the side of the transfer assembly 20 opposite to the carrier 11 during loading and to supply gas to the multiple through slots 22 to transfer the workpiece located at the transfer position 21 to the corresponding carrier position 112. It is also used to place on the side of the carrier 11 opposite to the transfer assembly 20 during unloading and to supply gas to the receiving slot 111 to transfer the workpiece located at the carrier position 112 to the corresponding transfer position 21. For example, the elastic member 13 can be a spring.

[0030] When the aforementioned material transfer device 100 is loading material, firstly, the clamping component 10 is positioned above and on the transfer component 20 so that the workpiece on the transfer position 21 corresponds to the corresponding bearing position 112; then, the clamping component 10 and the transfer component 20 are flipped together, and the ejector component 30 is placed on the side of the transfer component 20 away from the bearing member 11 and gas is supplied to multiple through slots 22 so that the workpiece falls into the corresponding bearing position 112 under the combined action of gas and gravity; finally, the rotating component 14 rotates relative to the bearing member 11 along the preset direction and abuts against the side wall of the bearing member 11 so as to drive the linkage component 12 to compress the elastic component 13 to the slot wall of the receiving slot 111, so that multiple clamping components 15 clamp the corresponding workpiece to the slot wall of the through slot 113; When the material transfer device 100 is unloading, firstly, the transfer assembly 20 is placed above the clamping assembly 10 and placed on the clamping assembly 10 so that the workpiece on the bearing position 112 corresponds to the corresponding transfer position 21; then, the clamping assembly 10 and the transfer assembly 20 are flipped together, and the workpiece is placed on the side of the bearing member 11 away from the transfer assembly 20; finally, the rotating member 14 rotates relative to the bearing member 11 in a direction opposite to the preset direction and abuts against the side wall of the bearing member 11, so as to drive the linkage member 12 to move away from the elastic member 13, so that multiple clamping members 15 are released from the corresponding workpieces. At the same time, the ejector assembly 30 delivers gas to the receiving groove 111 so that the gas is blown toward the workpiece through the connecting groove 121 and the through groove 113, so that the workpiece falls into the corresponding transfer position 21 under the combined action of gas and gravity.

[0031] Thus, in the material transfer device 100, the ejector component 30 is placed on the side of the transfer component 20 away from the carrier component 11 during loading and supplies gas to multiple through slots 22 to quickly and stably transfer the workpiece located at the transfer position 21 to the corresponding carrier position 112. During unloading, the ejector component 30 is placed on the side of the carrier component 11 away from the transfer component 20 and supplies gas to the receiving slot 111 to quickly and stably transfer the workpiece located at the carrier position 112 to the corresponding transfer position 21. This achieves flexible loading and unloading of workpieces through the combined action of gas and gravity, preventing the workpieces from being damaged by hard pushing during loading and unloading operations, thereby improving the product quality of the workpieces. At the same time, manual loading and unloading operations are not required, thus improving the material transfer efficiency.

[0032] It should be noted that the transfer assembly 20 is roughly plate-shaped, and each transfer position 21 is provided with a transfer groove 23. A through groove 22 is located at the bottom of the corresponding transfer groove 23 and communicates with the corresponding transfer groove 23. During loading and unloading operations, the transfer groove 23 corresponds to the side of the bearing member 11 away from the linkage member 12, so that the workpiece can be transferred between the clamping assembly 10 and the transfer assembly 20. The aforementioned preset direction can be clockwise or counterclockwise, as long as it can achieve the workpiece clamping operation.

[0033] Please see Figure 2 and Figure 5 In some embodiments, the ejection assembly 30 includes an air blowing member 31 and a connecting member 32. The air blowing member 31 is configured to be placed on the side of the transfer assembly 20 away from the carrier member 11 during loading and on the side of the carrier member 11 away from the transfer assembly 20 during unloading. The air blowing member 31 has an air inlet groove 311 and a plurality of air outlet grooves 312, each of which corresponds to a plurality of connecting grooves 121 and a plurality of through grooves 22. Each air outlet groove 312 is connected to the air inlet groove 311. The connecting member 32 is connected to the air inlet groove 311 and an external air source, respectively. The connecting member 32 is configured to deliver gas to the plurality of air outlet grooves 312 through the air inlet groove 311 under the guidance of the external air source.

[0034] Thus, through the above configuration, when the connecting member 32 is loaded, air is blown into the multiple through slots 22 through the air inlet slot 311 and multiple air outlet slots 312 respectively by the external air source. When unloading, air is blown into the multiple connecting slots 121 through the air inlet slot 311 and multiple air outlet slots 312 respectively by the external air source. This ensures that the air pressure in the multiple through slots 22 remains consistent during loading and that the air pressure in the multiple through slots 113 remains consistent during unloading. This enables the rapid and stable blowing out of multiple workpieces, avoiding insufficient air pressure in some areas that prevents the workpieces from being blown out, or excessive air pressure in some areas that causes the workpieces to be blown out too quickly and collide with other components. This improves the stability of material transfer and the product quality of the workpieces.

[0035] Please see Figure 2 and Figure 5 In some embodiments, the ejection assembly 30 further includes a seal 33. The seal 33 surrounds a plurality of air outlet grooves 312 and is connected to the air blowing member 31. The seal 33 is used to abut against the carrier 11 to seal the connection between the carrier 11 and the air blowing member 31. Exemplarily, the seal 33 may be a sealing ring.

[0036] Thus, through the above configuration, the seal 33 can form an end face seal between the air blowing component 31 and the carrier component 11, preventing gas from leaking from the connection between the two, thereby ensuring that the air blowing component 31 stably delivers gas to the carrier component 11 or the transfer assembly 20, and improving the stability of material transfer.

[0037] Please see Figure 2 In some embodiments, the clamping assembly 10 further includes a guide 16. The guide 16 is movably disposed through the linkage 12 along a first direction and rotatably connected to the carrier 11, and the guide 16 is configured to guide the linkage 12.

[0038] Thus, through the above configuration, the guide member 16 can guide the linkage member 12 along the first direction, eliminate the lateral force generated when the rotating member 14 drives the linkage member 12 to move, prevent the linkage member 12 from jamming or shifting, and thereby improve the clamping accuracy and material transfer accuracy.

[0039] Please see Figure 2 and Figure 3 In some embodiments, the linkage 12 is provided with a limiting groove 122, which is spaced apart from the communicating groove 121 along a third direction. The clamping assembly 10 also includes a limiting member 17, which is movably inserted through the limiting groove 122 along a second direction and connected to the bearing member 11. The limiting member 17 is configured to abut against the groove wall of the limiting groove 122 to limit the movement distance of the linkage 12.

[0040] Thus, through the above-mentioned settings, the limiting member 17 and the limiting groove 122 cooperate to limit the movement range of the linkage member 12 in the first direction within a set range, avoiding excessive movement of the linkage member 12 toward the elastic member 13, which would cause the clamping member 15 to damage the workpiece, and excessive movement of the linkage member 12 away from the elastic member 13, which would cause a collision with the bearing member 11. This ensures that the clamping member 15 stably clamps the workpiece, improves the clamping stability and the product quality of the workpiece, and at the same time ensures that the overlap of the multiple connecting grooves 121 with the corresponding through grooves 113 is consistent when the workpiece is released, which is conducive to the stable delivery of gas through the connecting grooves 121 to the through grooves 113, thereby ensuring the stability and accuracy of material transfer.

[0041] Please see Figure 2 In some embodiments, the rotating member 14 includes a movable body 141, a first rotating shaft 142, a second rotating shaft 143, and a rotating body 144. The movable body 141 is movably disposed through the bearing member 11 in a first direction, the first rotating shaft 142 is movably disposed through the movable body 141 and the linkage member 12 in a second direction, and is rotatably connected to the movable body 141 and the linkage member 12 respectively, and the second rotating shaft 143 is movably disposed through the end of the movable body 141 away from the linkage member 12 in a second direction. The rotating body 144 is disposed on one side of the bearing member 11 and rotatably connected to the second rotating shaft 143. The side wall of the rotating body 144 is provided with a locking surface 1441 and a loosening surface 1442 connected to each other. The distance between the locking surface 1441 and the second rotating shaft 143 is greater than the distance between the loosening surface 1442 and the second rotating shaft 143. The locking surface 1441 is configured to abut against the side wall of the bearing member 11 to drive the movable body 141 to move the linkage member 12 closer to the elastic member 13. The loosening surface 1442 is configured to abut against the side wall of the bearing member 11 to drive the movable body 141 to move the linkage member 12 away from the elastic member 13.

[0042] Thus, by utilizing the distance difference between the locking surface 1441 and the releasing surface 1442 and the second rotating shaft 143, the rotating body 144 can switch between the locking surface 1441 or the releasing surface 1442 and the side wall of the bearing member 11 to achieve workpiece clamping or releasing operations. This eliminates the need for complex mechanisms for locking and releasing operations, reducing operating costs and optimizing the structural layout.

[0043] Please see Figure 2 In some embodiments, the linkage 12 is provided with a storage groove 123 on the side facing the rotating member 14, and the storage groove 123 is configured to store part of the elastic member 13.

[0044] Thus, through the above settings, the receiving groove 123 can limit the elastic element 13, preventing the elastic element 13 from shifting or twisting when compressed or elastically opened, ensuring that the elastic element 13 stably provides elastic force, thereby ensuring that the clamping element 15 stably releases the workpiece, and further improving the material transfer stability.

[0045] Please see Figure 2 In some embodiments, the end of the clamping member 15 away from the linkage member 12 is provided with a flexible body 151, which is used to flexibly clamp the workpiece. For example, the flexible body 151 can be made of urethane, silicone, etc.

[0046] Thus, through the above-mentioned configuration, the flexible body 151 can form a flexible contact with the workpiece, avoiding indentations or scratches on the workpiece and ensuring the product quality of the workpiece. At the same time, the flexible body 151 can produce slight deformation to accommodate the dimensional tolerances of the workpiece, thereby improving the applicability of the clamping assembly 10.

[0047] Please see Figure 2 and Figure 3 In some embodiments, the bearing position 112 is provided with a receiving groove 114, the bottom wall of the receiving groove 111 is provided with a through groove 113, and the groove wall of the receiving groove 114 is configured to clamp the two sides of the workpiece respectively with the clamping member 15.

[0048] Thus, through the above arrangement, the receiving groove 114 is connected to the through groove 113, which can increase the contact area with the workpiece, so that the clamping member 15 abuts against the groove wall of the receiving groove 111 and the groove wall of the through groove 113, so as to achieve stable clamping of the workpiece, avoid vibration and shaking of the workpiece during processing, and improve the clamping stability of the clamping assembly 10.

[0049] Please see Figure 2 In some embodiments, the support member 11 has a positioning hole 115 on the side away from the linkage member 12, and the transfer assembly 20 has a positioning member 24 on the side facing the support member 11. The positioning member 24 is inserted into the positioning hole 115 to position the support member 11 and the transfer assembly 20.

[0050] Thus, with the above settings, when loading and unloading workpieces, the positioning member 24 is inserted into the positioning hole 115, which enables the carrier member 11 to accurately dock with the transfer assembly 20, thereby positioning the carrier member 11 and the transfer assembly 20. This ensures that the multiple carrier positions 112 on the carrier member 11 correspond one-to-one with the multiple transfer positions 21 on the transfer assembly 20, thereby ensuring that the workpiece is accurately transferred from the carrier member 11 to the transfer assembly 20 or from the transfer assembly 20 to the carrier member 11, thus improving the transfer accuracy.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
