[0049] Example

[0050] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, this embodiment provides a blanking mechanism, including a main blanking mechanism 10 and an auxiliary blanking mechanism 20; the main blanking mechanism 10 includes a first transfer mechanism 11, a transition carrier 12 and a second transfer mechanism 13, the transition carrier 12 is arranged between the first transfer mechanism 11 and the second transfer mechanism 13, the transition carrier 12 includes at least two variable-pitch carriers 121 and a rotating unit 122 that drives multiple variable-pitch carriers 121 to rotate and switch to the position of adjacent variable-pitch carriers 121; the variable-pitch carrier 121 is provided with a transverse slide rail 1211, multiple first carrier blocks 1212 arranged on the transverse slide rail 1211, and a unit that drives multiple first carrier blocks 1212 to merge Or a spaced-apart lateral power module 1213; the first transfer mechanism 11 is provided with a first support frame 111 that elevates itself, and the first transfer mechanism 11 includes a clamping unit 112 and a first power unit 113 that drives the clamping unit 112 to move to or away from above the variable-distance carrier 121; the second transfer mechanism 13 is provided with a second support frame 131 that elevates itself, and the second transfer mechanism 13 includes a first transfer member 132 and a second power unit 133 that drives the first transfer member 132 to move to or away from above the variable-distance carrier 121; the auxiliary unloading mechanism 20 has the same structural design as the main unloading mechanism 10, and the auxiliary unloading mechanism 20 is arranged side by side with the main unloading mechanism 10.

[0051] In this embodiment, both the main unloading mechanism 10 and the auxiliary unloading mechanism 20 are used to unload products from the feed tray 401 onto the unloading tray 301. If the feed tray 401 and the unloading tray 301 have the same dimensions, unloading can be performed without the need for variable pitch (i.e., adjusting the length or width of the variable pitch tray 121). If the feed tray 401 and the unloading tray 301 have different dimensions, such as a different length or width, the variable pitch tray 121 is used to adjust and adapt them, achieving efficient unloading.

[0052] Specifically, the variable-pitch carrier 121 can push the first carrier block 1212 via a transverse power module 1213 (which can be driven by a linear motor, pneumatic cylinder, or hydraulic cylinder), causing multiple first carrier blocks 1212 to sequentially abut and merge along the transverse slide 1211, thereby achieving the purpose of variable-pitch adjustment, so that the specifications of the variable-pitch carrier 121 and the blanking carrier 301 are the same. Subsequently, the second transfer mechanism 13 transfers the products in the variable-pitch carrier 121 to the blanking carrier 301, and outputs them via the blanking slide unit 30, achieving the purpose of automated unloading. In this way, the adaptability between carriers of different specifications is achieved, while achieving the effect of automated and efficient production.

[0053] Furthermore, the transition carrier 12 can be provided with multiple variable-pitch carriers 121 according to the material unloading rate. For example, two variable-pitch carriers 121 can be rotated 180° by a rotation unit 122 (which can be a servo motor) to achieve simultaneous loading and unloading operations on the transition carrier 12. The design of more than two variable-pitch carriers 121 can be adapted to be used with multiple first transfer mechanisms 11 and / or second transfer mechanisms 13, thereby matching the loading and unloading rates or improving the efficiency of unloading.

[0054] Furthermore, if Figure 2 and Figure 3 As shown, in this embodiment, the first transfer mechanism 11 includes a clamping unit 112 and a power unit that drives the clamping unit 112 to move back and forth between the variable-pitch carrier 121 and the feed conveyor 40. The clamping unit 112 includes a longitudinal slide 1121, a plurality of second carrier blocks 1122 slidably disposed on the longitudinal slide 1121, a longitudinal power module 1123 that drives the plurality of second carrier blocks 1122 to merge or separate at intervals, and a plurality of second transfer members 1124 disposed on the second carrier blocks. The transfer members are used to transfer products from the feed carrier 401 to the variable-pitch carrier 121. The power unit includes a linear slide and a lifting cylinder. The clamping unit 112 is mounted on the lifting cylinder for lifting and lowering; the lifting cylinder is mounted on the linear slide for linear reciprocating movement.

[0055] Specifically, a variable distance adjustment function is designed in the first transfer mechanism 11 to achieve size adjustment in different directions (for example, the variable distance carrier 121 adjusts the spacing horizontally, and the clamping unit 112 adjusts the spacing vertically, thus adjusting the length and width of the carrier), thereby improving flexibility. When in use, the second carrier block 1122 is pushed by the longitudinal power module 1123 (which can be driven by a linear motor, a cylinder, or a hydraulic cylinder), so that multiple second carrier blocks 1122 are pressed against each other in turn and merged along the longitudinal slide rail 1121, thereby achieving the purpose of variable distance adjustment and making the clamping unit 112 and the variable distance carrier 121 compatible. In this way, the size adjustment can be performed in the longitudinal direction, as well as the lateral size adjustment of the variable distance carrier 121, thereby improving the flexibility of adjustment and being able to adapt to more types of carriers. Of course, if the unloading carrier 301 is the same as the feeding carrier 401, no adjustment is required, and the unloading operation can be performed directly.

[0056] In this embodiment, the second transfer mechanism 13 comprises a linear slide, a lifting cylinder, and a fixed plate mounted with vacuum cups. The number of vacuum cups is equal to the number of product placement slots on the unloading tray 301, and they are designed to be aligned with the unloading tray 301. The fixed plate is mounted on the lifting cylinder for lifting and lowering; the lifting cylinder is mounted on the linear slide for linear reciprocating motion, transferring products from the variable-pitch tray 121 to the unloading tray 301, completing the unloading operation.

[0057] like Figure 1 and Figure 2 As shown, this embodiment also includes a discharge slide unit 30 and a feeding conveyor belt 40, a feeding tray 401 is provided on the feeding conveyor belt 40, a transition tray 12 is provided between the discharge slide unit 30 and the feeding conveyor belt 40, and a discharge slide unit 30 is provided with a discharge tray 301; a storage rack 302 is provided at the end of the discharge slide unit 30.

[0058] Specifically, the unloaded product is placed on the feeding tray 401, and is transported to the position of the first transfer mechanism 11 by the feeding conveyor 40, and then stops or the feeding tray 401 is lifted. The first transfer mechanism 11 transfers the product on the feeding tray 401 to the variable-pitch tray 121 (the transfer method can be vacuum adsorption, magnetic attraction, or pneumatic clamping, etc.). At this time, the variable-pitch tray 121 can push the first carrier block 1212 through the transverse power module 1213 (which can be driven by a linear motor, cylinder, or hydraulic cylinder), so that multiple first carrier blocks 1212 are pressed against each other in turn and merged along the transverse slide rail 1211, thereby achieving the purpose of variable-pitch adjustment, so that the variable-pitch tray 121 has the same specifications as the unloading tray 301. Then, the products in the variable-pitch carrier 121 are transferred to the unloading carrier 301 through the second transfer mechanism 13, and output through the unloading slide rail unit 30 to achieve the purpose of automated unloading, thereby achieving adaptation between carriers of different specifications and achieving automated and efficient production.

[0059] During use, the power unit drives the clamping unit 112 to move onto the feed tray 401. The lifting cylinder then drives the clamping unit 112 downward, allowing the product on the feed tray 401 to be suctioned or clamped by the first transfer member 132 before returning to its original position. At this point, the second carrier block 1122 can be adjusted for pitch as needed. After the pitch adjustment is complete, the linear slide moves horizontally, positioning the transfer member above the pitch-variable tray 121. The lifting cylinder then drives the product onto the pitch-variable tray 121 again, before returning the product to its original position. This process is repeated to achieve efficient transfer and pitch adjustment.

[0060] Furthermore, in this embodiment, the first transfer member 132 and the second transfer member 1124 can be vacuum suction cups, magnetic suction parts, or pneumatic grippers, and can be used according to the corresponding device design of the product. For example, diaphragms can be adsorbed by vacuum suction cups; products with magnetic materials can be magnetically attracted by electromagnets or permanent magnets; and products that are easy to grasp can be clamped by pneumatic grippers. This has good practicality and design flexibility.

[0061] Furthermore, if Figure 2 As shown, the design of the first support frame 111 and the second support frame 131 in this embodiment can enable the first transfer mechanism 11 and the second transfer mechanism 13 to be located above the transition carrier 12, forming a hierarchical arrangement of different heights, making the design of the unloading mechanism more compact.

[0062] like Figure 1 and Figure 2As shown, in this embodiment, the feed tray 401 has more product slots than the unloading tray 301, and the feed tray 401 has fewer product slots than the sum of the product slots on the two unloading trays 301. Thus, the auxiliary unloading mechanism 20 performs independent unloading of products, forming two unloading lines for the feed conveyor 40; alternatively, multiple unloading lines can be provided as needed to improve unloading efficiency. Alternatively, if the feed tray 401 has more product slots than the unloading tray 301, the auxiliary unloading mechanism 20 can complete all unloading operations for the feed tray 401.

[0063] Specifically, let's take a feed tray 401 with 4*6 product placement slots, a discharge tray 301 with 4*4 product placement slots, a variable-pitch tray 121 with 4*4 product placement slots, and both the second transfer mechanism 13 and the clamping unit 112 with 4*4 vacuum suction cups. The clamping unit 112 of the first transfer mechanism 11 clamps the 4*4 products from the feed tray 401. After two horizontal and vertical shifts, the second transfer mechanism 13 aligns the products on the variable-pitch tray 121 and transfers them to the discharge tray 301, completing the unloading process for this assembly line.

[0064] At this point, there are two rows or two columns of eight products remaining on the feed tray 401. These products are then transported to the auxiliary unloading mechanism 20 via the feed conveyor 40. The clamping unit 112 of the first auxiliary transfer mechanism then clamps the remaining 2*4 products on the feed tray 401. After two horizontal and vertical shifts, the second auxiliary transfer mechanism aligns the products on the auxiliary variable-pitch tray 121 and transfers them to the unloading tray 301, completing the unloading of the remaining products on the feed tray 401. Furthermore, the auxiliary unloading mechanism 20 can fill the unloading tray 301 with products in a 4*4 format through two unloading operations, thus achieving complete unloading of the feed tray 401. This resolves the issue of differences in specifications and quantities between the feed tray 401 and the unloading tray 301, improving practicality.

[0065] like Figure 4 As shown, in this embodiment, a first limit strip 1214 is provided between two adjacent first carrier blocks 1212, one end of the first limit strip 1214 is provided with a first fixing hole 12141 that is locked on a first carrier block 1212, the other end of the first limit strip 1214 is provided with a first bar hole 12142, and the other first carrier block 1212 is provided with a first limit pin 12143 that passes through the first bar hole 12142 for limiting the position.

[0066] Specifically, after the first carrier blocks 1212 have completed their pitch changes and need to be reset, the first limit bars 1214 can be used for position adjustment. That is, when the lateral power module 1213 drives the first carrier blocks 1212 in the opposite direction, one of the two adjacent first carrier blocks 1212 will move along the first bar-shaped hole 12142 via the first limit pin 12143 until it stops after hitting the first limit pin 12143, thus achieving the purpose of separation.

[0067] like Figure 6 As shown, in this embodiment, a second limit strip 1125 is provided between two adjacent second carrier blocks 1122, one end of the second limit strip 1125 is provided with a second fixing hole 11251 locked on a second carrier block 1122, the other end of the second limit strip 1125 is provided with a second bar hole 11252, and the other second carrier block 1122 is provided with a second limit pin 11253 that passes through the second bar hole 11252 for limiting the position.

[0068] Similarly, when the second carrier blocks 1122 need to be reset after their displacement has been completed, the second limiting bars 1125 can be used for position adjustment. That is, when the longitudinal power module 1123 drives the second carrier blocks 1122 in the reverse direction, one of the two adjacent second carrier blocks 1122 will move along the second bar-shaped hole 11252 via the second limiting pin 1125330253 until it stops upon contact, thereby achieving separation.

[0069] Furthermore, if Figure 7 As shown, in this embodiment, the unloading carrier 301 includes a fixed block 3011 arranged on the unloading slide unit 30, a loading cylinder 3012 arranged on the fixed block 3011, and a placement plate 3013 arranged on the output shaft of the loading cylinder 3012. The unloading carrier 301 is arranged on the placement plate 3013, the loading cylinder 3012 can be a dual-axis cylinder, and the unloading slide unit 30 can be a linear slide.

[0070] Specifically, the unloading slide rail unit 30 drives the fixed block 3011 (which can be a slider) to move back and forth, and the unloading tray 301 filled with products is moved to the bottom of the storage rack 302. Then, the loading cylinder 3012 can drive the unloading tray 301 to be lifted so that the unloading tray 301 can be placed in the storage rack 302, realizing a lifted and stacked placement on the storage rack 302. There is a pair of baffles at the bottom of the storage rack 302 that can only be flipped up, so as to achieve the effect of stacking.

[0071] Furthermore, if Figure 7As shown, in this embodiment, the bottom of the storage rack 302 is provided with two symmetrical and upwardly turned limit baffles 3021 and a plurality of stop shafts 3022 for abutting and limiting the limit baffles 3021 in a horizontal position; the distance between the two limit baffles 3021 is greater than the width of the placement tray 3013, and the distance between the two limit baffles 3021 is less than the width of the unloading tray 301. The second storage rack 302 has the same structural arrangement as the storage rack 302. In this way, the purpose of stacking from bottom to top is achieved, achieving the effect of storage and placement.

[0072] Furthermore, if Figure 1 As shown, this embodiment also includes an auxiliary unloading rail unit 50, which has the same structural design as the unloading rail unit. A storage rack 302 is provided at the end of the unloading rail unit 30. The storage rack 302 is also provided at the end of the auxiliary unloading rail unit 50. Unloading trays 301 can be stacked to form a certain storage capacity, so that batch transportation can be carried out through the storage rack 302, reducing the frequency of handling and improving practicality.

[0073] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
