For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] like Figure 1 and Figure 2 As shown, the limiting mechanism provided by the embodiment of the utility model includes: a limiting assembly 100, a supporting assembly and a driving assembly. The limiting assembly 100 includes a one-way block 110 and a transmission block 120. The one-way block 110 is rotatably connected to the transmission block 120 via a first rotating shaft 130. The transmission block 120 is movably connected to the supporting assembly. The driving assembly is transmission-connected to the transmission block 120. The driving assembly drives the one-way block 110 to move via the transmission block 120.
[0029] Specifically, the limiting mechanism provided in the embodiment of the utility model is installed on the side wall of the bin 400 through the supporting assembly, and the axis of the first rotating shaft 130 is parallel to the side wall of the bin 400. The one-way block 110 has a limiting state and an unlocking state. When placing chips in the tray, the one-way block 110 is in the limiting state, that is, the one-way block 110 is arranged in the horizontal direction to support the tray for placing chips; when the stacked trays are stacked with the tray above the one-way block 110, the one-way block 110 is driven by the transmission block 120 to move to the unlocking state, so that all the stacked trays can move downward.
[0030] During the chip testing process, the tray on which the chips are to be placed is placed above the one-way block 110, and the tested chips are placed in the tray above the one-way block 110. When the tray on the one-way block 110 is full of chips, the lifting mechanism 500 drives the stacked trays to rise so that the stacked trays are stacked with the trays above the one-way block 110. During the lifting process of the lifting mechanism 500, the stacked trays push the one-way block 110 to rotate around the first rotating shaft 130 in the direction away from the silo 400, and then the driving assembly drives the transmission block 120 to drive the one-way block 110 to move further in the direction away from the silo 400 to release the limit of the one-way block 110 on the tray. Afterwards, the lifting mechanism 500 drives the stacked trays to move downward to the bottom of the one-way block 110, thereby completing the tray closure. After the tray closure is completed, the one-way block 110 and the transmission block 120 return to their original positions under the action of their own gravity. When the closing position of the tray is inaccurate, since the one-way block 110 moves to the unlocking position in two stages, the highest point of the movement trajectory of the one-way block 110 can be lowered to prevent the one-way block 110 from contacting the tray above it, thereby avoiding the problem of chips in the tray shaking, trembling or knocking the tray over.
[0031] As a way of movably connecting a transmission block 120 with a supporting assembly, the transmission block 120 is rotatably connected with the supporting assembly via a second rotating shaft 140, the one-way block 110 includes a limit end 111, the limit end 111 protrudes from the transmission block 120, the first rotating shaft 130 is movably passed through the one-way block 110 and is spaced apart from the limit end 111, and the first rotating shaft 130 is parallel to the second rotating shaft 140; the driving assembly is used to drive the transmission block 120 to rotate around the axis of the second rotating shaft 140, and at the same time, the limit end 111 can rotate with the first rotating shaft 130 as the axis, so that the limit end 111 can limit and release the limit on the material tray located above the one-way block 110.
[0032] like Figure 1As shown, the second rotating shaft 140 is arranged in a direction parallel to the first rotating shaft 130, and passes through the transmission block 120 to be rotatably connected to the support assembly. The one-way block 110 is in a long strip shape and is arranged in a direction perpendicular to the first rotating shaft 130. The one-way block 110 includes a limiting end 111, which is located outside the transmission block 120 and is used to support and limit the material tray. The first rotating shaft 130 is movably arranged in the one-way block 110 and is spaced apart from the limiting end 111, and the first rotating shaft 130 is rotatably connected to the transmission block 120. When the limiting mechanism is installed on the side wall of the silo 400, the limiting end 111 is opposite to the silo 400, the first rotating shaft 130 is located on the side of the limiting end 111 away from the silo 400, and the second rotating shaft 140 is located on the side of the first rotating shaft 130 away from the silo 400, that is, the distance between the second rotating shaft 140 and the silo 400 is greater than the distance between the first rotating shaft 130 and the silo 400. The driving assembly is in transmission connection with the transmission block 120, and is used to drive the transmission block 120 to rotate around the second rotating shaft 140, so that the transmission block 120 drives the one-way block 110 to move.
[0033] After the stacked material trays push the one-way block 110 to rotate around the first rotating shaft 130 in the direction away from the material bin 400, the driving assembly drives the transmission block 120 to drive the one-way block 110 to rotate around the second rotating shaft 140 in the direction away from the material bin 400, so that the one-way block 110 rotates to an unlocked state. Since the distance between the second rotating shaft 140 and the material bin 400 is greater than the distance between the first rotating shaft 130 and the material bin 400, the highest point of the motion trajectory of the limit end 111 rotating around the second rotating shaft 140 is lower than the lowest point of the motion trajectory rotating around the first rotating shaft 130, preventing the one-way block 110 from contacting the material tray above it, thereby avoiding the problem of shaking, trembling or knocking over the chips in the material tray above it.
[0034] As an installation method of the one-way block 110 , the one-way block 110 can be directly installed on the top wall or the side wall of the transmission block 120 through the first rotating shaft 130 .
[0035] As another installation method of the one-way block 110, Figure 2 As shown, the transmission block 120 is provided with a mounting groove 150, which passes through the top wall of the transmission block 120 and is adapted to the one-way block 110. The limiting end 111 of the one-way block 110 is located outside the mounting groove 150, and the other end of the one-way block 110 is located inside the mounting groove 150 and is rotatably connected to the side wall of the mounting groove 150 through the first rotating shaft 130.
[0036] Specifically, the opening of the mounting groove 150 is arranged at the middle of the top wall of the transmission block 120, wherein the top wall of the transmission block 120 refers to the outer wall on which the transmission block 120 is located when the limiting assembly 100 is installed on the side wall of the silo 400; the mounting groove 150 extends through the two side walls of the transmission block 120 in a direction perpendicular to the first rotating shaft 130. The end of the one-way block 110 away from the limiting end 111 is located in the mounting groove 150, and is rotatably connected to the side wall of the mounting groove 150 through the first rotating shaft 130. The limiting end 111 is located outside the mounting groove 150 to limit the material tray located above it; when the one-way block 110 is in the limiting state, the bottom wall of the one-way block 110 abuts against the bottom wall of the mounting groove 150 to prevent the one-way block 110 from rotating downward and affecting the support of the material tray. A mounting groove 150 is provided on the transmission block 120, and one end of the one-way block 110 is located in the mounting groove 150, so that the one-way block 110 is connected to the transmission block 120. Since the one-way block 110 and the transmission block 120 have partial structural overlap, the space occupied by the overall structure of the one-way block 110 and the transmission block 120 can be reduced.
[0037] Furthermore, the one-way block 110 also includes a connecting end, which is connected to the transmission block 120 via the first rotating shaft 130 .
[0038] Specifically, the connecting end is an arc-shaped surface with the axis of the first rotating shaft 130 as the axis center, and the arc-shaped surface is tangent to the bottom wall of the mounting groove 150. When the one-way block 110 is in the limited state, the bottom wall of the one-way block 110 abuts against the bottom wall of the mounting groove 150, and when the stacked material trays move upward, the limited end 111 of the one-way block 110 is pushed to rotate around the first rotating shaft 130 in a direction away from the bottom wall of the mounting groove 150, and at the same time, the connecting end also rotates around the first rotating shaft 130 in a direction close to the silo 400. The connecting end is set to an arc shape, so that the connecting end is easier to move relative to the bottom wall of the mounting groove 150 abutting against it, so that the stacked material trays are easier to push up the limited end 111.
[0039] like Figure 1 As shown, the transmission block 120 is installed with a limit rod 160, which is opposite to and spaced from the one-way block 110 and parallel to the first rotating shaft 130. The limit rod 160 is partially located in the installation groove 150 and on the side of the one-way block 110 away from the second rotating shaft 140. The side wall of the installation groove 150 is stepped. Specifically, Figure 2As shown, the side wall of the mounting groove 150 includes a first side wall portion 151 and a second side wall portion 152 connected in one piece, the height of the first side wall portion 151 is higher than the height of the second side wall portion 152, the one-way block 110 is rotatably connected to the first side wall portion 151 through the first rotating shaft 130, the limiting rod 160 is located above the one-way block 110, and the two ends are respectively connected to the first side wall portions 151 on both sides; when the one-way block 110 is in a limited state, the mounting groove 150 is extended from one end of the second side wall portion 152 away from the first side wall portion 151. When the one-way block 110 is driven to rotate to a set position, it abuts against the limiting rod 160, and the limiting rod 160 defines the limit position of the one-way block 110 rotating upward.
[0040] When the transmission block 120 is rotationally connected to the supporting assembly, as a driving mode, the driving assembly includes a rotating driving member, the rotating driving member is located on one side of the transmission block 120, the rotating shaft of the rotating driving member is connected and fixed to the second rotating shaft 140, the second rotating shaft 140 is rotationally connected to the supporting assembly and fixedly connected to the transmission block 120, the rotating shaft drives the second rotating shaft 140 to rotate, thereby driving the transmission block 120 to rotate.
[0041] When the transmission block 120 is rotationally connected to the supporting assembly, as another driving mode, the driving assembly includes a linear driving member 310, the driving shaft of the linear driving member 310 is transmission-connected to the bottom wall of the transmission block 120, and the movement direction of the driving shaft of the linear driving member 310 is set at an angle greater than zero degrees with the axis of the first rotating shaft 130.
[0042] Specifically, the linear drive member 310 can be set as a cylinder or a hydraulic cylinder, etc. The linear drive member 310 is fixedly installed on the support assembly, and the driving shaft of the linear drive member 310 is located below the transmission block 120 and is arranged on the side of the second rotating shaft 140 close to the limit end 111 in the vertical direction. When the limit of the material tray needs to be released, the driving shaft of the linear drive member 310 moves upward, and the driving shaft pushes the transmission block 120 to drive the one-way block 110 to rotate around the second rotating shaft 140, so that the one-way block 110 changes to an unlocked state. When the one-way block 110 needs to change to a limited state, the driving shaft moves downward, and the one-way block 110 and the transmission block 120 rotate downward under the action of their own gravity, so that the one-way block 110 changes to a limited state. The driving assembly includes the linear drive member 310, and the linear drive member 310 is located below the transmission block 120, which can reduce the space occupied by the limit mechanism in the horizontal direction.
[0043] like Figure 1 and Figure 2As shown, the support assembly includes a support block 210, and the transmission block 120 is rotatably connected to the support block 210 via a second rotating shaft 140; the support block 210 is provided with a transmission hole 212, and the extension direction of the transmission hole 212 is perpendicular to the rotation axis of the one-way block 110, and the driving shaft of the linear drive member 310 passes through the transmission hole 212 and is opposite to the transmission block 120.
[0044] like Figure 3 As shown, the transmission hole 212 passes through the support block 210 in the vertical direction, the linear drive member 310 is fixedly installed at the lower end of the support block 210, and the driving shaft of the linear drive member 310 passes through the transmission hole 212 and faces the bottom wall of the transmission block 120. The support block 210 supports and fixes the transmission block 120 and the linear drive member 310. By installing the support block 210 on the side wall of the silo 400, the installation of the limit assembly 100 is realized, and the installation operation is convenient.
[0045] like Figure 2 and Figure 3 As shown, the support block 210 is provided with a support groove 211, the transmission block 120 includes a flipping part 121 and a connecting part 122 which are fixedly connected to each other, the one-way block 110 is rotatably connected to the flipping part 121 through a first rotating shaft 130, the connecting part 122 is located in the support groove 211, and is rotatably connected to the side wall of the support groove 211 through a second rotating shaft 140.
[0046] Specifically, the support groove 211 penetrates the top wall and the rear side wall of the support block 210, and the transmission hole 212 penetrates the bottom wall of the installation groove 150. The flip part 121 is located outside the installation groove 150. When the one-way block 110 is in the limited state, the bottom wall of the flip part 121 abuts against the top wall of the support block 210, the connecting part 122 is arranged at an angle with the flip part 121, and is located in the installation groove 150. The second rotating shaft 140 passes through the connecting part 122 and is rotatably connected to the side wall of the installation groove 150. One end of the flip part 121 close to the connecting part 122 is in an outwardly convex arc shape. A support groove 211 is provided on the support block 210, and the connecting portion 122 of the transmission block 120 is located in the mounting groove 150, so that the flip block and the support block 210 partially overlap in structure, which is beneficial to reducing the occupied space. In addition, one end of the flip portion 121 close to the connecting portion 122 is in an outwardly convex arc shape. When the flip portion 121 rotates around the second rotating shaft 140, the flip portion 121 is easier to move relative to the top wall of the support block 210 abutting against it, thereby making it easier for the linear drive member 310 to push up the flip block.
[0047] As another way of movably connecting the transmission block 120 and the support assembly, the transmission block 120 and the support assembly are slidably matched, and the sliding direction of the transmission block 120 is set at an angle greater than zero with the axis of the first rotating shaft 130.
[0048] Specifically, the support assembly includes a support block 210, on which a slide rail is fixedly connected. The slide rail is arranged in a horizontal direction, and the extension direction of the slide rail is perpendicular to the axis of the first rotating shaft 130. The transmission block 120 is equipped with a slider that slides with the slide rail. The drive assembly includes a cylinder or a hydraulic cylinder. Specifically, taking a cylinder as an example, the cylinder body of the cylinder is fixedly installed on the support block 210, and the driving end of the cylinder is connected to the transmission block 120. The cylinder drives the transmission block 120 to move along the slide rail, so that the transmission block 120 drives the one-way block 110 to switch between a limited state and an unlocked state. The transmission block 120 drives the one-way block 110 to slide along the horizontally arranged slide rail, which can lower the highest point of the movement trajectory of the one-way block 110, prevent the one-way block from contacting the topmost tray, and thereby cause the chips in the tray to shake, tremble or knock the tray over.
[0049] like Figure 4 As shown, the disk closing device provided by the embodiment of the utility model includes a silo 400, a lifting mechanism 500 and a plurality of the above-mentioned limiting mechanisms, the lifting mechanism 500 is arranged in the silo 400, the plurality of limiting mechanisms are arranged on the two side walls of the silo 400, and the limiting ends 111 of the plurality of limiting mechanisms are opposite to the silo 400.
[0050] like Figure 5 As shown, the lifting mechanism 500 includes a motor 510, a screw rod 520, a nut and a tray 530. The screw rod 520 is arranged in the vertical direction, and the lower end of the screw rod 520 is connected to the motor 510. The nut is threadedly matched with the screw rod 520 and fixedly connected to the tray 530. The tray 530 is arranged in the horizontal direction to support the stacked material trays. Four, six or eight limit assemblies 100 can be provided. In this embodiment, four limit assemblies 100 are provided, of which two limit assemblies 100 are provided on one side wall of the silo 400, and the other two limit assemblies 100 are provided on the other side wall of the silo 400. The positions of the limit assemblies 100 on the two side walls correspond one to one, and the limit ends 111 in each limit assemblies 100 are opposite to the silo 400.
[0051] Multiple one-way blocks 110 cooperate to support the trays on which chips are to be placed. When the trays on the tray blocks are full of chips, the motor 510 drives the screw rod 520 to rotate, so that the nut drives the tray 530 and the stacked trays on the tray 530 to rise, so that the stacked trays are stacked with the trays above the one-way block 110. At the same time, the stacked trays push the one-way block 110 to rotate around the first rotating shaft 130 in the direction away from the silo 400, and then the driving component drives the transmission block 120 to drive the one-way block 110 to move further in the direction away from the silo 400, thereby releasing the limit on the trays, and the lifting mechanism 500 drives the stacked trays to move downward to the bottom of the one-way block 110, thereby completing the tray closure. After the tray closure is completed, the one-way block 110 and the transmission block 120 return to their original positions. When the closing position of the tray is inaccurate, since the one-way block 110 moves to the unlocking position in two stages, the highest point of the movement trajectory of the one-way block 110 can be lowered to prevent the one-way block 110 from contacting the top tray, thereby causing the chips in the tray to shake, tremble or knock the tray over.
