Description

Technical Field

[0001] The invention relates to the technical field of chip mounting, and in particular to a material pushing device and a material unloading mechanism. Background Art

[0002] Materials are often transported using a conveyor belt, which has a simple structure and is easy to control. For example, chip mounting equipment is usually used in the assembly of semiconductor chips during production. After the chip is mounted or needs to be transferred to other workstations, it needs to be transferred between different transportation platforms. The commonly used transportation platform is a conveyor belt. The material cannot completely contact the conveyor belt at the end of the transportation platform, causing the material to stagnate at the end of the transportation platform, thereby affecting the transportation to the next workstation.

[0043] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0044] See also Figure 1-Figure 5 This embodiment provides a pushing device, which mainly includes a bottom plate 30, a limit block 31, a pushing component 32, a hinge block 33, a push handle 34 and a spring 35.

[0045] The limiting block 31 is fixed on the bottom plate 30, and the limiting block 31 has a limiting portion 311; the pushing component 32 is fixed on the bottom plate 30 and is located on one side of the limiting block 31, such as Figure 3-Figure 5 The pushing component 32 is located on the left side of the limiting block 31. The pushing component 32 may be a cylinder, which is mainly used to push the hinge block 33 and the push handle 34 to move;

[0046] The hinge block 33 is connected to the transmission shaft 321 of the pushing member 32, and the hinge block 33 has a first hinge portion 331 and a first connecting portion 332; the push handle 34 has a second hinge portion 341 and a second connecting portion 342, and the first hinge portion 331 is hinged with the second hinge portion 341 so that the push handle 34 can rotate relative to the hinge block 33, and a stopper 343 is arranged on the push handle 34; the spring 35 is connected to the first connecting portion 332 and the second connecting portion 342 in a stretched state; the push handle 34 has a first state and a second state, and in the first state, the limit portion 311 contacts the stopper 343 so that the free end of the push handle 34 bends downward (such as Figure 4 In the second state, the transmission shaft 321 of the pushing member 32 pushes the hinge block 33 away from the limit block 31, so that the limit portion 311 releases the resistance to the stopper 343, and the free end of the push handle 34 is lifted upward under the pulling force of the spring 35 (as shown in FIG. Figure 5 shown).

[0047] The pusher device of the above embodiment works as follows: When the pusher device is not in use, refer to Figure 3 and Figure 4 , the transmission shaft 321 of the pushing component 32 contracts, and the hinge block 33 approaches the limit block 31, so that the limit portion 311 abuts against the stopper 343. When the limit portion 311 abuts against the stopper 343, the hinge block 33 continues to move, which will cause the push handle 34 to rotate around the center of the second hinge portion 341. During this process, the stretched length of the spring 35 changes in real time and is always in a stretched state. When the pushing device is needed to push the material, refer to Figure 5, the transmission shaft 321 of the pushing component 32 extends out, and the hinge block 33 moves away from the limit block 31, so that the stopper 343 set on the push handle 34 is no longer interfered by the limit portion 311, and the push handle 34 as a whole is lifted up under the pulling force of the spring 35, so that the free end of the push handle 34 can push the material forward. After the free end of the push handle 34 is lifted up, the transmission shaft 321 of the pushing component 32 continues to extend to push the material forward.

[0048] The pushing device of the above embodiment is raised when pushing materials and lies down when not pushing materials, thereby reducing space occupation and can be flexibly applied to various transportation platforms to ensure the reliability and effectiveness of material transportation.

[0049] In some embodiments, the limit block 31 has two limit portions 311 , and the two limit portions 311 are spaced apart. When the push handle 34 is in the first state, a portion of the hinge block 33 is located directly below the limit portions 311 , and a portion of the push handle 34 is located between the two limit portions 311 .

[0050] Specifically, there is a space between the two limiting portions 311 that can at least partially accommodate the hinge block 33. When the push handle 34 is in the first state, the hinge block 33 fits in the space. Figure 4 and Figure 5 , the side surface of the limiting block 31 can be L-shaped.

[0051] In some embodiments, the limit block 31 has a first upper surface 312 parallel to the base plate 30, and the push handle 34 has a second upper surface 344 and a third upper surface 345 that are angled to each other; when the push handle 34 is in the first state, the second upper surface 344 is parallel to the first upper surface 312 or is located on the lower side of the plane where the first upper surface 312 is located, and the third upper surface 345 is located on the lower side of the plane where the first upper surface 312 is located; when the push handle 34 is in the second state, the second upper surface 344 and the first upper surface 312 are angled to each other, and the third upper surface 345 is located on the upper side of the plane where the first upper surface 312 is located.

[0052] When the second upper surface 344 is parallel to the first upper surface 312 or located below the plane where the first upper surface 312 is located, other components or materials can be allowed to pass above the push handle 34, thereby reducing or avoiding interference with other components or materials.

[0053] Furthermore, the hinge block 33 has a first limiting portion 334, and the push handle 34 has a second limiting portion 347. When the push handle 34 is in the second state, the first limiting portion 334 stops the second limiting portion 347, so that the third upper surface 345 is parallel to the first upper surface 312. By providing the first limiting portion 334 and the second limiting portion 347, the upward lifting range of the push handle 34 is limited, so that the free end of the push handle 34 can push the material at a predetermined position.

[0054] In some embodiments, the first hinged portion 331 and the second hinged portion 341 are hinged through the first axis 333, and the first connecting portion 332 is the second axis connected to the hinge block 33. The main function of the first connecting portion 332 is to provide a connection point for the spring 35. In addition to using an axis, other structures can also be used. It is only necessary to ensure that the spring 35 can be stably connected to the hinge block 33. For example, the first connecting portion 332 can also be a hook set on the hinge block 33.

[0055] The second connection portion 342 is a third axis connected to the push handle 34. The main function of the second connection portion 342 is to provide a connection point for the spring 35. In addition to the axis, other structures can also be used. It is only necessary to ensure that the spring 35 can be stably connected to the push handle 34. For example, the second connection portion 342 can also be a hook set on the push handle 34.

[0056] In some embodiments, the stopper 343 includes a fixed shaft connected to the push handle 34 and a bearing disposed on the fixed shaft, and the bearing can roll and rub with the limiting portion 311. When the transmission shaft 321 of the pushing component 32 is in the process of contraction, the limiting portion 311 contacts the bearing, and the bearing starts to rotate, and the free end of the push handle 34 gradually bends downward during the rotation of the bearing. The friction force of rolling friction is small, which can make the transmission shaft 321 of the pushing component 32 easier to contract.

[0057] Furthermore, the surface of the limiting portion 311 (the contact surface with the bearing) can be set to an inclined surface or a curved surface to adjust the rotation speed and rotation trajectory of the push handle 34.

[0058] In some embodiments, the free end of the pushing handle 34 has a plurality of spaced-apart pushing fingers 346, and a plurality of spaced-apart grooves or insertion holes 301 are provided on the bottom plate 30. When the pushing handle 34 is in the first state, the plurality of pushing fingers 346 are inserted one by one into the plurality of grooves or insertion holes 301, thereby further reducing the space occupied by the pushing handle 34 when not pushing materials.

[0059] This embodiment further provides a transport platform, which can be used as a material unloading platform on a chip mounting assembly line, and can also be used for transporting other materials.

[0060] Specifically, see Figure 6-Figure 7The transport platform includes: a loading platform 11, a first transmission belt assembly 12, a second transmission belt assembly 13, a driving assembly 14, an adjusting assembly 15 and a pushing device of any of the above embodiments, the first transmission belt assembly 12 and the second transmission belt assembly 13 are arranged in parallel and spaced apart, the first transmission belt assembly 12 and the second transmission belt assembly 13 are used to transport materials, and the driving assembly 14 is connected to the first transmission belt assembly 12 and the second transmission belt assembly 13 to drive the first transmission belt assembly 12 and the second transmission belt assembly 13 to transport materials along a first direction.

[0061] According to the size of the conveyed material, the spacing between the first transmission belt assembly 12 and the second transmission belt assembly 13 is adjustable. In order to achieve the adjustable spacing, an adjusting assembly 15 is arranged on the loading machine platform 11. The adjusting assembly 15 is transmission-connected with the second transmission belt assembly 13 to drive the second transmission belt assembly 13 to move along the second direction, and the first direction is perpendicular to the second direction; a pushing device is arranged between the first transmission belt assembly 12 and the second transmission belt assembly 13, and is close to the conveying ends of the first transmission belt assembly 12 and the second transmission belt assembly 13. The pushing device is used to push the material away from the first transmission belt assembly 12 and the second transmission belt assembly 13.

[0062] The material on the transport platform is first transported by the first transmission belt assembly 12 and the second transmission belt assembly 13. When the material moves to the conveying end, the material is pushed forward by the pushing device to ensure that the material is smoothly separated from the first transmission belt assembly 12 and the second transmission belt assembly 13.

[0063] When the pusher 34 is in the first state (i.e. when no material is being pushed), it is lower than the material bearing surface of the first transmission belt assembly 12 and the second transmission belt assembly 13, ensuring that the normal material conveying of the first transmission belt assembly 12 and the second transmission belt assembly 13 is not affected. When the material needs to be pushed, the pusher 34 is raised, and the position of the free end of the pusher 34 is higher than or equal to the material bearing surface of the first transmission belt assembly 12 and the second transmission belt assembly 13, so as to facilitate pushing the material from the material bearing surface of the first transmission belt assembly 12 and the second transmission belt assembly 13 to the next workstation.

[0064] In some embodiments, the adjustment component 15 includes a first drive motor 151 and a first transmission shaft 152. The first drive motor 151 is fixed to the loading machine 11. The first transmission shaft 152 connects the first drive motor 151 and the second transmission belt assembly 13. The second transmission belt assembly 13 is arranged on the loading machine 11 through the guide rail 111 and can slide along the guide rail 111. The extension direction of the guide rail 111 is parallel to the second direction. The first drive motor 151 drives the second transmission belt assembly 13 to move along the guide rail 111 through the first transmission shaft 152 to adjust the spacing between the first transmission belt assembly 12 and the second transmission belt assembly 13.

[0065] Therefore, by providing the guide rail 111, the movement of the second transmission belt assembly 13 can be made more stable and less prone to skewing during movement, so that the first drive motor 151 can more easily drive the second transmission belt assembly 13 to move along the second direction.

[0066] Specifically, two parallel guide rails 111 are provided on the loading platform 11 and are respectively located on both sides of the adjusting assembly 15 . The first driving motor 151 drives the second transmission belt assembly 13 to move at the middle position of the second transmission belt assembly 13 .

[0067] In some embodiments, at least two motor installation positions are provided on the feeding machine 11, and at least two motor installation positions are spaced apart along the second direction. The first drive motor 151 is fixed at any motor installation position, and the first drive motor 151 corresponds to an adjustable spacing range of the first transmission belt assembly 12 and the second transmission belt assembly 13 in each motor installation position. Therefore, the first drive motor 151 can be selected to be installed at different positions according to different application scenarios.

[0068] Specifically, the at least two motor installation positions include a first installation position 112 , a second installation position 113 and a third installation position 114 , and the first drive motor 151 can switch positions at any of the first installation position 112 , the second installation position 113 and the third installation position 114 .

[0069] For example, when the first drive motor 151 is installed in the first installation position 112, the spacing range of the first transmission belt assembly 12 and the second transmission belt assembly 13 is 50mm-150mm, when the first drive motor 151 is installed in the second installation position 113, the spacing range of the first transmission belt assembly 12 and the second transmission belt assembly 13 is 150mm-200mm, and when the first drive motor 151 is installed in the third installation position 114, the spacing range of the first transmission belt assembly 12 and the second transmission belt assembly 13 is 200mm-250mm.

[0070] In some embodiments, a first sensor 16 is further provided on the feeding machine 11. The first sensor 16 is used to detect the position of the second transmission belt assembly 13, and to send out an alarm signal or control the first drive motor 151 to stop driving when the second transmission belt assembly 13 moves to the travel limit position. By providing the first sensor 16, it is possible to prevent the first drive motor 151 from continuing to drive the second transmission belt assembly 13 to move to the travel limit position, thereby preventing the first drive motor 151 from burning out or the second transmission belt assembly 13 from being pulled out.

[0071] For example, the first sensor 16 may be a photoelectric switch. When the second transmission belt assembly 13 moves to a position where it blocks the first sensor 16 , the photoelectric switch cuts off the power supply of the first driving motor 151 .

[0072] In some embodiments, the installation position of the first sensor 16 changes with the installation position of the first drive motor 151. That is to say, the first sensor 16 also has multiple installation positions. The first sensor 16 changes the installation position synchronously with the first drive motor 151 to ensure that the power supply of the first drive motor 151 can be cut off by the first sensor 16 when the first drive motor 151 is in each installation position.

[0073] In some embodiments, the first transmission shaft 152 is a lead screw that passes through the first drive motor 151 .
