Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a step-type single-station pressing mechanism. Background Technology

[0002] In traditional pressing processes, the system achieves precise component pressing through the linkage of upper and lower modules: first, the conveying mechanism accurately positions the pallet carrying the product to the lower mold station; then, the lower mold performs a lifting action to form a mold closing space with the upper mold; finally, the tight joining of the internal components of the product is completed through the coordinated pressure of the upper and lower modules. When the points on the product that need to be pressed interfere with each other and require step-by-step pressing, and the points of each pressing step have the same geometric arrangement characteristics in spatial layout and only have an overall positional offset, if a multi-station pressing machine is designed, an independent module needs to be configured for each pressing step, resulting in complex equipment structure, high cost, and low pressing efficiency due to the need for repeated positioning and product transfer in multi-station pressing. There is an urgent need to design a stepping single-station pressing mechanism to solve the problems existing in the current technology. Utility Model Content

In this embodiment, the structure of the upper quick-change mounting mold and the upper fixture is the prior art and is not a protected point of this utility model, so it will not be described in detail here. In other embodiments, the upper quick-change mounting module 12 may not be provided, and the upper fixture may be directly fixed on the piston rod of the lifting cylinder 11.

[0017] like Figure 4 As shown, the conveying assembly 20 is used to convey a tray with a fixed product. The conveying assembly 20 includes a first belt conveyor line fixedly mounted on a fixed plate 50 and a second belt conveyor line 21 mounted on the fixed plate 50 via a third mounting plate 60. A first roller group 22 is provided on the side of the first belt conveyor line to guide the movement of the tray, and a second roller group 23 is provided on the side of the second belt conveyor line 21 to guide the movement of the tray.

[0018] In this embodiment, the lower fixture assembly 30 is disposed between the first belt conveyor line and the second belt conveyor line 21. For example... Figures 5-7As shown, the lower fixture assembly 30 includes a lower fixture module, a horizontal drive module that drives the lower fixture module to move along the conveying direction of the conveying assembly 20, and a lifting drive module that drives the horizontal drive module to rise and fall. The lifting drive module includes a first mounting plate 31, a lead screw module located below the first mounting plate 31 and mounted on the first mounting plate 31, a first linear guide module mounted on the first mounting plate 31, and a second linear guide module mounted on the nut 33 of the lead screw module. The axial direction of the lead screw 32 of the lead screw module is arranged in the vertical direction. The first linear guide module includes a first linear bearing 35 fixedly mounted on the first mounting plate 31 and a first guide rod 36 passing through the first linear bearing 35. The second linear guide module includes a second linear bearing 37 fixedly mounted on the nut 33 and a second guide rod 38 passing through the second linear bearing 37.

The top of the second guide rod 38 is fixed on the first mounting plate 31, and the bottom of the second guide rod 38 is used to mount the drive component of the lead screw module. One end of the lead screw 32 of the lead screw module is mounted on the first mounting plate 31 via a bearing, and the other end is connected to the drive component of the lead screw module. In this embodiment, the drive component of the lead screw module is a motor 34. The bottom of the second linear bearing 37 and the first guide rod 36 are fixed to the nut 33 via the second mounting plate 39. In this embodiment, the lead screw module, in conjunction with the first linear guide module and the second linear guide module, synchronously drives the horizontal drive module to rise and fall via the nut 33, ensuring the accuracy of the lower fixture module's vertical movement.

[0019] The horizontal drive module includes a first drive component and a linear guide module. The lower fixture module is mounted on the movable part of the first drive component and the slide of the linear guide. In this embodiment, the first drive component is an electric cylinder 310. In this embodiment, the lower fixture module includes a lower quick-change mounting module 311 and a lower fixture (not shown in the figure) detachably mounted on the lower quick-change mounting module 311. The lower fixture can be replaced when pressing different products. In this embodiment, the structure of the lower quick-change mounting module and the lower fixture is prior art and is not a protected feature of this utility model, so it will not be described in detail here. In other embodiments, the lower quick-change mounting module 311 may not be provided, and the upper fixture may be directly fixed on the movable part of the electric cylinder 310 and the slide of the linear guide.

[0020] The stop assembly 40 is used to block the forward movement of the pallet on the conveying assembly 20. In this embodiment, the stop assembly 40 is mounted on the lower quick-change mounting module 311, and its structure includes a blocking member 41 and a second driving member that drives the blocking member 41 to rotate or move up and down. The second driving member is a rotary clamping cylinder 42. The first mounting plate 31 is fixed on the third mounting plate 60; the lifting driving member is mounted on the fourth mounting plate 70, and the fourth mounting plate 70 is fixed on the third mounting plate 60. In this embodiment, the horizontal driving module is mounted on the fifth mounting plate 80.

[0021] by Figure 1 With the direction as a reference, the working principle of a stepping single-station pressing mechanism in this utility model is as follows: (1) The initial state is: the piston rod of the lifting cylinder 11 of the upper fixture assembly 10 retracts; the nut 33 of the lead screw module of the lower fixture assembly 30 is located at the lowest end of its stroke, so that the lower fixture module is located below the carrier plate on the conveying assembly 20; the length direction of the blocking member 41 of the stop assembly 40 is perpendicular to the conveying direction of the conveying assembly 20; the moving part of the electric cylinder 310 is located at the leftmost end of its stroke. (2) Start-up action: The conveying assembly 20 conveys the pallets placed on the first belt conveyor line and the second belt conveyor line 21 forward. When the sensor detects that the pallet has been conveyed to the predetermined position, the piston rod of the rotary clamping cylinder 42 extends, driving the blocking member 41 to rise and rotate, stopping the pallet directly above the lower fixture module. Then, the output shaft of the motor 34 rotates, driving the lead screw 32 to rotate. The rotation of the lead screw 32 drives the nut 33 to rise. The rise of the nut 33 drives the horizontal drive module to rise, which in turn drives the lower fixture module to rise. The lower fixture module lifts the pallets stopped on the first belt conveyor line and the second belt conveyor line 21 upward. The lower fixture module stops rising at the predetermined position, causing the pallets to detach from the first belt conveyor line and the second belt conveyor line 21. At the same time, the rotary clamping cylinder 42 drives the second blocking member 41 to reset, that is, to descend and rotate 90° in the opposite direction. The upper and lower fixture modules are rotated 90° in the opposite direction to avoid interference with the pressing of the upper and lower fixture modules. The piston rod of the lifting cylinder 11 extends, driving the upper fixture module to descend and press against the lower fixture module for the first pressing of the product. After the first pressing, the piston rod of the lifting cylinder 11 retracts, and the electric cylinder 310 drives the lower fixture module to move to the right to a predetermined position, so that the point on the product that needs to be pressed for the second time is directly below the upper fixture module. The piston rod of the lifting cylinder 11 extends again, driving the upper fixture module to descend and press against the lower fixture module for the second pressing of the product. Then the piston rod of the lifting cylinder 11 retracts, and the motor 34 drives the nut 33 to move downward, thereby driving the lower fixture module to descend and place the pressed product on the first belt conveyor line and the second belt conveyor line 21 for forward transport. Then it returns to the initial state, and this cycle repeats.
