Description

Technical Field

[0001] The invention belongs to the technical field of fruit and vegetable planing, and more specifically, relates to an integrated automatic production line for sanding, polishing and cleaning of a fruit and vegetable planer handle. Background Art

[0002] Fruit and vegetable planers are a kind of daily necessity, which are basically used every day. Conventional fruit and vegetable planers are mainly used for convenient shredding. With the progress of society, fruit and vegetable planers have become more diverse. Through different knives, they can be used for shredding, slicing, and some can even be used to cut flower slices, providing more variety for our dishes and convenient use.

[0003] Currently, there are many types of fruit and vegetable graters on the market, including flat graters and vertical multi-sided graters. These generally include a grater, a grating frame, and a handle. For example, Chinese Design Patent Publication No. CN300711640, entitled "Food Grater (Four-Sided with Drag Plates)," discloses a vertical multi-sided fruit and vegetable grater with an all-metal handle consisting of a horizontal metal grip and two vertical metal connecting plates. The upper ends of the two metal connecting plates are welded to the ends of the metal grip, and the lower ends of the two metal connecting plates are provided with slots that connect to the grating frame.

[0004] The all-metal handle of the vertical multi-faceted fruit and vegetable scraper needs to go through multiple process steps from processing to forming, including the processing of the metal handle, the processing of the metal connecting plate, and the processing after welding the metal handle and the connecting plate.

[0005] At present, in the handle processing industry of vertical multi-sided fruit and vegetable planers, the processes of handle weld grinding, surface polishing, cleaning and drying are separated from each other. That is, manual loading and unloading is required during weld grinding, surface polishing, and cleaning and drying. Fully automatic processing cannot be achieved, the workers' workload is high, and production efficiency is low. Summary of the Invention

[0006] The purpose of the present invention is to solve the above-mentioned technical problems and to provide an integrated automatic production line for sanding, polishing and cleaning of fruit and vegetable planer handles, which reduces manual labor and improves production efficiency.

[0007] The present invention is achieved through the following technical solutions.

[0008] The present invention provides an integrated automatic production line for sanding, polishing and cleaning of a fruit and vegetable planer handle, comprising a material storage table, a weld grinder, an automatic polisher, a transfer table, a six-axis robot and a cleaning and drying machine, wherein:

[0009] The material storage platform includes a material storage base and a material storage plate. The surface of the material storage plate is provided with slots that match the ends of the two connecting plates of the handle. Two slots form a group, and each group of slots can hold a handle.

[0014] There are two six-axis robots, which are respectively arranged on the left and right sides of the third intermittent rotary worktable. The six-axis robot on the right side of the third intermittent rotary worktable is configured to transport the handle from the material storage plate to the handle fixture of the first intermittent rotary worktable, and to transport the handle polished by the weld grinder to the handle fixture of the third intermittent rotary worktable. The six-axis robot on the left side of the third intermittent rotary worktable is configured to transport the handle from the third intermittent rotary worktable to the handle fixture of the second intermittent rotary worktable, and to transport the handle polished by the automatic polishing machine to the cleaning and drying machine.

[0015] In the above technical solution, the six-axis robot on the right side of the third intermittent rotary worktable can transport the handle from the material storage plate to the weld grinder for weld grinding processing, and the polished handle is transported to the transfer transition table to wait for the polishing process. The six-axis robot on the left side of the third intermittent rotary worktable transports the handle on the transfer transition table to the automatic polishing machine for polishing the handle. The polished handle is transported to the cleaning and drying machine for cleaning and drying, realizing automatic processing throughout the process, greatly reducing manual labor and improving production efficiency.

[0016] Preferably, the handle clamp includes a fixed base, a movable clamping plate, and a cylinder. A movable clamping plate is provided on each side of the fixed base. The cylinder is disposed at the bottom of the fixed base, and the cylinder shaft of the cylinder is connected to the movable clamping plate. The movable clamping plate can be clamped and released from the fixed base by the cylinder. In this technical solution, the handle clamp is specifically designed for fruit and vegetable planer handles. The two movable clamping plates cooperate with the fixed base to clamp the bottom ends of the handle's two connecting plates, thus clamping the handle to ensure stability during subsequent processing.

[0017] Preferably, the free end of the six-axis robot is provided with a handle clamp, which includes a connecting plate, a clamp cylinder, a guide plate, and a clamp. The connecting plate is connected to the free end of the six-axis robot, and a clamp cylinder is provided at each end of the connecting plate. The bottom of each clamp cylinder is fixedly connected to the guide plate, and the bottom of the guide plate is slidably connected to two clamps. The clamp cylinder is configured to drive the two clamps toward and away from each other. In this technical solution, the specially designed handle clamp can clamp the handle for reliable and stable transportation between processes.

[0018] Preferably, the weld seam grinding mechanism includes a first X-axis servo module, a first column, a first Z-axis servo module, a Y-axis fine-tuning mechanism, and an abrasive belt mechanism.

In this technical solution, the Y-axis fine-tuning mechanism can adjust the position of the abrasive belt mechanism according to the different lengths and specifications of the handle, so that it can accurately grind the weld position. The first X-axis servo module and the first Z-axis servo module cooperate, so that the abrasive belt mechanism can grind the weld while the disc is intermittently stopped.

[0019] Preferably, the Y-axis fine-tuning mechanism includes a fixed plate, a movable plate, and a screw. The fixed plate is fixed to the first Z-axis servo module, and the movable plate is connected to the fixed plate via a screw. The abrasive belt mechanism is disposed on the movable plate.

In this technical solution, the second X-axis servo module and the second Z-axis servo module cooperate to allow the polishing wheel to polish the surface of the handle while the disc is intermittently stopped. The Y-axis servo module enables the polishing wheel to move along the Y-axis, that is, the polishing wheel can move along the axial direction of the handle. Even if the length of the handle is greater than the length of the polishing wheel, the surface of the handle can still be fully polished.

[0022] Preferably, the Y-axis servo module includes a base plate, a guide rail optical axis, a sliding seat, a Y-axis servo motor, an eccentric cam, and a connecting rod.

[0023] Preferably, a protection switch for removing components is installed on the corner of the material storage base near the weld grinder. The protection switch includes a vertically mounted switch lever. This allows the robot to remove components from the material storage base. If the six-axis robot also has a handle, the horizontal metal grip of the handle will contact the switch lever, triggering the protection switch and terminating the robot's removal process, thus preventing duplicate removal errors.

[0024] Preferably, the cleaning and drying machine includes a conveyor belt, and an ultrasonic cleaning module, a spray module, an ultrasonic rinsing module, an air-cutting module, and a drying module arranged sequentially from left to right. Thus, the polished handles are transported from left to right on the conveyor belt, enabling fully automatic cleaning, air-drying, and drying, thereby reducing manual labor.
