Description

Technical Field

[0001] The utility model relates to the technical field of alloy resistor repair equipment, in particular to a full-automatic laser repair equipment for alloy resistors. Background Art

[0002] Traditionally, alloy sheet resistance trimming involves grinding the resistor body with a grinding head. This produces a harsh noise and produces a large amount of metal debris. These large and heavy debris cannot be quickly removed by a vacuum cleaner, resulting in a buildup of debris on the equipment. The grinding head also contacts the resistor body during grinding, potentially causing miscalculations on the micro-ohmmeter. Grinding heads are consumable parts and require frequent replacement.

[0003] However, milling machine resistor repair and grinding machine resistor repair can only perform large-area uniform resistance repair, and cannot perform corresponding resistance value correction for individual resistors. The efficiency and accuracy are low and the cost is high.

[0004] Therefore, the resistance repair device in the prior art has a technical problem of being unable to repair the resistance of a single resistor. Summary of the Invention

[0013] The material unloading and conveying assembly is used to convey the material sheet after the resistance repair is completed to the material unloading silo assembly.

[0014] Preferably, the frame is further provided with a separation component, which blows off excess sheets on the loading and conveying component according to parameters detected by the multi-sheet detection component.

[0015] Preferably, the loading silo assembly includes at least one loading quick-release silo for storing sheets.

[0051] In some embodiments, the frame 1 is further provided with a separation component, which blows off excess sheets on the loading and conveying component 4 according to the parameters detected by the multi-sheet detection component.

[0052] The separation component may include an air pump and an air nozzle, wherein the air pump supplies air to the air nozzle, and the air flow ejected from the air nozzle blows off excess sheets.

[0053] Reference Figures 1 to 5 As shown, in some embodiments, the loading bin assembly 2 includes at least one loading quick-release bin for storing sheets.

[0054] The frame 1 is further provided with a pushing assembly, which is used to push the material sheets in the loading bin assembly 2 to move.

[0055] In some embodiments, the pusher assembly includes a pusher block and a synchronous belt for driving the pusher block to move.

[0056] In some embodiments, the unloading silo assembly 3 includes at least two unloading quick-release silos for storing sheets of different specifications, wherein each of the unloading quick-release silos stores sheets of the same specification.

[0057] Wherein, a pushing assembly corresponding to the quick-disconnect material bin for unloading can also be provided on the frame 1 at the location corresponding to the quick-disconnect material bin for unloading material.

[0058] In some embodiments, the resistance measuring component 7 includes a measuring probe and a moving module for moving the sheet, wherein the moving module includes a Y-axis module and an X-axis module disposed on the Y-axis module.

[0059] The moving module is used to drive the sheet to move in the X-axis and Y-axis directions.

[0060] Reference Figures 1 to 5 As shown, in some embodiments, the loading and conveying assembly 4 includes a loading suction cup for adsorbing the material sheet and a loading driving assembly for driving the loading suction cup to move.

[0061] In some embodiments, the material unloading and conveying assembly 5 includes a material unloading suction cup for adsorbing the material sheet and a material unloading driving assembly for driving the material unloading suction cup to move.

[0062] In some embodiments, the sheet positioning and placement table assembly 6 is provided with a stripping block and a stripping cylinder for driving the stripping block to move.

[0063] The above technical solution is described in detail below in combination with the working principle:

[0064] Reference Figures 1 to 5 As shown, the sheet to be repaired is placed in the loading hopper, which is then secured to the loading hopper assembly 2 via a locking block. After the equipment is started, a synchronous belt located below the loading hopper assembly 2 propels the pusher block upward, pushing the sheet to the designated position. The pusher block is connected to the synchronous belt via a connecting shaft and a connecting block.

[0065] The retrieving and conveying module in the loading and conveying assembly 4 drives the loading cylinder installed on it to the designated position. The action of the loading cylinder moves the loading suction cup installed on it to the top of the sheet to retrieve the sheet. The sensors in the multi-sheet detection assembly and the separation assembly installed behind the loading quick-release hopper detect the sucked sheet. If there are multiple sheets, the air nozzle in the separation assembly will blow off the excess sheets. The loading and conveying assembly 4 then conveys the sheet to the sheet positioning and placement platform assembly 6 for positioning and fixation.

[0066] The X-axis module and the Y-axis module arranged thereon move to deliver the sheet to the designated position. The measuring cylinder in the resistance measuring component 7 moves to drive the measuring probe to measure the sheet in turn. The laser resistance trimming component 8 trims the sheet according to the measured resistance value.

[0067] After the resistance is repaired, the X-axis module and the Y-axis module transport the blank positioning and placement table assembly 6 to the specified position. The material removal cylinder arranged on the lower side of the fixed plate of the blank positioning and placement table assembly 6 is actuated to raise the material removal block and push the blank away.

[0068] The unloading and conveying module in the unloading and conveying assembly 5 drives the unloading cylinder installed on it to the designated position. The unloading cylinder then moves the unloading suction cup installed on it to the top of the blank to collect the material. Then, according to different requirements, the blank is conveyed to the top of the unloading quick-release bin of the designated unloading bin assembly 3. The unloading cylinder drives the unloading suction cup installed on it to place the blank into the corresponding unloading quick-release bin.

[0069] The unloading hopper assembly 3 is provided with an unloading quick-release hopper and a pushing assembly consisting of a pushing drive, a connecting fixed block, a pushing block, a connecting shaft, a synchronous belt, etc. The pushing drive drives the synchronous belt to move the pushing block downward to sequentially collect the material sheets into the hopper.

[0070] After a batch of sheet materials is repaired, the push block is lowered to the bottom, the quick-release material bin is taken out and replaced with a new one.

[0071] The above describes the technical solution and corresponding details of the subject matter of the present invention. It can be understood that the above description is only some implementation plans of the technical solution of the subject matter of the present invention, and some details may be omitted during its specific implementation.

Those skilled in the art can freely combine and implement the above embodiments as needed in specific implementation to obtain a better application experience.
