Description

Technical Field

[0001] This application relates to the field of laser processing, and in particular to a feeding device and laser processing equipment. Background Technology

[0002] In the processing of 3C products, the loading of workpieces from trays or hoppers is generally involved. This loading operation typically uses robotic arms, but the cost of robotic arms is too high. Alternatively, there is a bottom-feeding method from the hopper. Specifically, a pair of conveyor belts are installed at the bottom of the hopper, and a lifting mechanism lifts the stacked workpieces above the conveyor belts. A pair of insert plates are then used to separate the bottom workpiece from the workpiece above it, while the insert plates receive the workpiece above. The bottom workpiece is then lowered onto the conveyor belt by the lifting device and unloaded. While this method is cheaper than robotic arm loading, the feeding operation involves more mechanisms, resulting in a complex structure and still relatively high cost. Utility Model Content

[0003] This application proposes a feeding device and laser processing equipment, which uses a simple driving component to drive the workpiece to be discharged from the bottom of the hopper, resulting in lower equipment cost.

[0013] In some embodiments, the hopper includes two spaced-apart trough-shaped members, with corresponding trough side plates on the same side of the two trough-shaped members. The hopper also includes two receiving strips disposed at the lower end of the trough-shaped members, one of which is used to connect the trough side plates on the same side of the two trough-shaped members, and the other is used to connect the trough side plates on the other side of the two trough-shaped members. The receiving strips are used to receive the workpiece, and the area between the two receiving strips forms a pushing channel for the pushing member to move along the first direction.

[0014] In some embodiments, the lower end of the grooved component is provided with a notch, the width of the notch is W1, the height of the notch is H, the width of the workpiece is W2, the thickness of the workpiece is D, W1 > W2, D < H < 2D, and the notch constitutes the discharge port.

[0017] First mounting bracket;

[0018] The second mounting frame is slidably connected to the first mounting frame along the second direction, and the hopper is disposed on the second mounting frame;

[0019] A switching drive unit is disposed on the first mounting bracket and is used to drive the first mounting bracket to slide along the second direction.

[0033] This application proposes a feeding device, referring to... Figures 1 to 4 The feeding device includes: a hopper 10, which is arranged vertically and vertically and has a discharge port 11 at its lower end, the discharge port 11 being located on the side of the hopper 10; a pusher 21, located below the hopper 10; a lifting drive 24, used to drive the pusher 21 to rise and fall, the pusher 21 rising to dock with the workpiece in the hopper 10; and a pushing drive 22, used to drive the pusher 21 to move along a first direction, so that the pusher 21 pushes the workpiece in the hopper 10 out from the discharge port 11.

[0034] In this embodiment, the lifting drive 24 drives the pusher 21 to rise and fall, allowing the pusher 21 to dock with the workpiece in the hopper 10. The pusher drive 22 drives the pusher 21 to move along a first direction, causing the pusher 21 to push the workpiece in the hopper 10 out of the outlet 11. Subsequently, the pusher 21 is driven down by the lifting drive 24 to separate from the pushed-out workpiece, and then driven back to below the hopper 10 by the pusher drive 22. The lifting drive 24 can then drive the pusher 21 to rise again and dock with the workpiece at the bottom of the hopper 10, completing the next round of discharge. This device uses only two drive components for cyclic discharge, resulting in a simpler structure and lower equipment cost.

[0035] Furthermore, the aforementioned pusher 21 can be in the form of a plate, with a groove on its upper surface corresponding to the workpiece. The workpiece can be placed in the groove, and the depth of the groove is less than the thickness of the workpiece. Of course, in addition to using a groove structure, a protrusion can also be provided on the upper surface of the pusher 21. The protrusion is used to hold the side of the workpiece to complete the pusher process, and the height of the protrusion is less than the thickness of the workpiece.

[0036] In some embodiments, the feeding device further includes a receiving frame 30 disposed on one side of the hopper 10, with one end of the receiving frame 30 facing the discharge port 11, for receiving workpieces pushed out by the pusher 21. In this embodiment, the receiving frame 30 includes two upright plates 31 spaced apart along a second direction, and a limiting strip 32 disposed on the upper end of the upright plates 31. The length direction of the limiting strip 32 is along a first direction, and the upper end of the upright plates 31 is used to receive the workpiece, which can slide between the two limiting strips 32. In this embodiment, the receiving frame 30 is used to receive the workpiece, and the side wall of the limiting strip 32 forms a limiting step with the upper end of the upright plate 31, limiting the two sides of the workpiece to restrict the sliding direction of the workpiece. In addition, the upper surface of the limiting strip 32 is also provided with an opening. Since the side of the workpiece may be provided with a barcode or QR code, when the workpiece moves to the set area of ​​the receiving frame 30, the barcode scanner on the side of the receiving frame 30 can scan the barcode or QR code through the opening to identify the workpiece.

[0037] Furthermore, the pushing drive component 22 is located between the two upright plates 31. The feeding device also includes a mounting base 23 that is driven and connected to the pushing drive component 22. The lifting drive component 24 is located on the mounting base 23, and the pushing component 21 is slidably connected to the mounting base 23 in the vertical direction. In this embodiment, the pushing drive component 22 can be a long-stroke cylinder. The push rod of the long-stroke cylinder is set towards the side where the hopper 10 is located, and the mounting base 23 is connected to the push rod. The mounting base 23 and the pushing component 21 can move between the two upright plates 31. The lifting drive component 24 can be a lifting cylinder. A connecting plate can be set on the lower side of both ends of the pushing component 21. The connecting plate is slidably connected to the mounting base 23 below in the vertical direction, and the lifting cylinder can be located between the two connecting plates. Of course, the above-mentioned pushing drive component 22 can also be a double-rod cylinder, which can ensure that the pushing component 21 will not deflect when it is raised or lowered, and the above-mentioned connecting plate can be omitted.

[0038] Furthermore, the feeding device also includes a first buffer 25 disposed above the pusher drive, the first buffer 25 being used to abut against the mounting base 23. Specifically, a connecting seat can be disposed above the end of the pusher drive away from the hopper 10, and the first buffer 25 is disposed on the connecting seat. When the mounting base 23 and the pusher 21 push the workpiece out along the first direction, the first buffer 25 can buffer the connecting seat to reduce the vibration of the device.

[0039] In some embodiments, the hopper 10 includes two spaced-apart groove-shaped members 12, with corresponding groove side plates 13 on the same side of the two groove-shaped members 12. The hopper 10 also includes two receiving strips 14 disposed at the lower end of the groove-shaped members 12. One receiving strip 14 is used to connect the groove side plates 13 on the same side of the two groove-shaped members 12, and the other receiving strip 14 is used to connect the groove side plates 13 on the other side of the two groove-shaped members 12. The receiving strips 14 are used to receive workpieces, and the area between the two receiving strips 14 forms a pushing channel for the pusher 21 to move in a first direction. In this embodiment, the two groove-shaped members 12 are vertically arranged. One end of the workpiece in the hopper 10 can be disposed in one of the groove-shaped members 12, and the other end is located in the other groove-shaped member 12. The two ends and sides of the workpiece are limited by the groove-shaped members 12. The receiving strips 14 can receive the areas of the two side edges of the workpiece, and the pusher 21 can move between the two receiving strips 14 to push the workpiece. Furthermore, the lower end of the grooved component 12 has a notch with a width of W1 and a height of H. The width of the workpiece is W2, and the thickness of the workpiece is D, where W1 > W2 and D < H < 2D. The notch forms a discharge port 11. In this embodiment, the grooved component 12 includes a groove side plate 13 and a groove bottom plate. The groove bottom plate is used to connect two spaced-apart groove side plates 13. The aforementioned notch is located at the lower end of the groove bottom plate.

[0040] In some embodiments, the feeding device further includes a switching mechanism 40 and a plurality of hoppers 10 disposed on the switching mechanism 40; the hoppers 10 are arranged along a second direction, and the switching mechanism 40 is used to drive the hoppers 10 to move along the second direction, so that each hopper 10 corresponds to the pusher 21. In this embodiment, when all the workpieces in one hopper 10 are pushed out laterally, the switching mechanism 40 can drive the hopper 10 to move, so that the other hopper 10 moves above the movement trajectory of the pusher 21, thus completing the switching of the hoppers 10. Of course, when the switching mechanism 40 moves, the pusher 21 can be in the pushed-out state, i.e., located in the receiving frame 30, or located directly below the hopper 10. When the pusher 21 is located directly below the hopper 10, it needs to be kept in a downward state to move away from the hopper 10 above, so as to avoid getting stuck between the two receiving bars 14 and restricting the switching movement of the hopper 10. In this embodiment, two hoppers 10 can be set, and the two hoppers 10 are driven by a cylinder to translate to complete the switching operation. Of course, more than two hoppers 10 can be set up. The hoppers 10 are moved by electric cylinders. The stroke of the electric cylinders is controllable, which can ensure that each hopper 10 can correspond to the pusher 21 below.

[0041] Specifically, the switching mechanism 40 includes: a first mounting frame 41; a second mounting frame 42, slidably connected to the first mounting frame 41 along a second direction, with the hopper 10 disposed on the second mounting frame 42; and a switching drive 43, disposed on the first mounting frame 41, for driving the first mounting frame 41 to slide along the second direction. In this embodiment, two hoppers 10 can be provided, and the switching drive 43 can be a cylinder, which can be named a switching cylinder, used to drive the two hoppers 10 to translate and complete the switching operation. The switching cylinder can be disposed on the side of the first mounting frame 41 away from the receiving frame 30, which is the back side of the first mounting frame 41. The second mounting frame 42 is disposed on the front side of the first mounting frame 41, and the two are slidably connected by a slide rail and a slider, with the sliding direction along the second direction, and the first direction being perpendicular to the second direction. One end of the second mounting frame 42 also passes through the first mounting frame 41 and extends to the back side of the first mounting frame 41, and is connected to the drive end of the switching cylinder. In addition, the first mounting bracket 41 is provided with a second buffer for abutting against the second mounting bracket 42, and the second buffer is used to buffer the movement of the second mounting bracket 42.

[0042] This application also proposes a laser processing equipment, which includes the aforementioned feeding device. The laser processing equipment further includes a machine base for mounting the feeding device. In this embodiment, the feeding device is mounted on the machine base. Specifically, the aforementioned receiving frame 30, pushing drive component 22, and first mounting frame 41 can be arranged along a first direction and mounted on the machine base. Of course, the laser processing equipment may also include a marking head positioned above the receiving frame 30, or a scanner located on the side of the receiving frame 30. The marking head is used to mark the upper surface of the workpiece, and the scanner can be used to acquire barcode or QR code information from the sidewall of the workpiece.

[0043] In this embodiment, the working principle of the feeding device and laser processing equipment is as follows: The feeding device and laser processing equipment include a hopper 10, a pusher 21, a lifting drive 24, and a pusher drive 22; the hopper 10 is arranged vertically and vertically and has a discharge port 11 at the lower end, which is located on the side of the hopper 10; the pusher 21 is located below the hopper 10, and the lifting drive 24 is used to drive the pusher 21 to rise and fall, so that the pusher 21 can reach the workpiece in the hopper 10; the pusher drive 22 is used to drive the pusher 21 to move along a first direction, so that the pusher 21 pushes the workpiece in the hopper 10 from the side of the discharge port 11, and then the pusher 21 is driven to fall by the lifting drive 24 and separate from the pushed workpiece, and is driven to retract to the bottom of the hopper 10 by the pusher drive 22, and the lifting drive 24 can drive the pusher 21 to rise again and reach the workpiece at the bottom of the hopper 10 to complete the next round of feeding. This device uses only two drive components for cyclic discharge, making it simpler in structure and lower in equipment cost.
