Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a V-groove cutting machine with a waste material adsorption structure. Background Art

[0002] Circuit boards are common centralized control components in electronic devices. When processing circuit boards, printed circuit boards need to be tested. In order to facilitate testing and save time, several printed circuit boards are usually combined into one for testing. After the test is completed, the upper and lower surfaces of each circuit board are cut into V-shaped grooves by a cutting machine, and then the circuit boards are broken and split separately, so a V-groove cutting machine is used;

[0003] In a V-groove cutting machine for aluminum-based circuit boards disclosed in publication number CN213907048U, after the position adjustment of the first slider is completed, the second clamping plate is pulled to make the connecting block slide on the connecting rod, so that the tension spring is in a compressed state, and then the aluminum-based circuit board is placed on the carrier plate and located between the first clamping plate and the second clamping plate, and then the second clamping plate is released, and under the tension of the tension spring, the connecting block drives the second clamping plate to slide, and cooperates with the first clamping plate to clamp the aluminum-based circuit board, and then the positioning rod is passed from the connecting hole of the positioning plate through the corresponding positioning groove on the first slider to slide and sleeve, and the position of the carrier plate is limited, and then the V-groove cutting machine can slide to perform V-groove cutting, and when the cutting is completed once, the positioning rod is pulled out, the carrier plate is moved so that the positioning plate corresponds to the adjacent first slider, and then the positioning rod is passed from the connecting hole of the positioning plate through the corresponding positioning groove on the first slider to slide and sleeve, and the position of the carrier plate is limited, so that the carrier plate drives the aluminum-based circuit board to move a certain distance, and then it can be cut again;

[0004] However, the above scheme still has the following problems during use: during use, the object to be processed is positioned by a positioning plate and a slider, and then slotted by a slotting machine, and waste is generated after slotting. With the continuous use of the continuous slotting machine, the waste will accumulate on the work surface and need to be cleaned manually, which is inconvenient.

[0005] Therefore, we propose a V-groove cutting machine with a waste adsorption structure to solve the above-mentioned problems. Utility Model Content

With the continuous use of the continuous groove cutting machine, the waste will accumulate on the work surface, which needs to be cleaned manually, which is inconvenient.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a V-groove cutting machine with a waste adsorption structure, comprising a workbench, a top frame is arranged on the top of the workbench, a telescopic rod is connected between the top frame and the workbench, a first motor is installed inside the top frame, and a reciprocating screw rod is connected to the output end of the first motor;

[0009] It also includes: a material suction pipe, wherein the material suction pipe is symmetrically bearing-connected to the front and rear sides of the slide frame, and the top of the material suction pipe is connected to the material collection box through a connecting pipe, and the material collection box is installed on the top of the top frame;

[0010] Positioning rods are equidistantly spaced and slidably connected to the middle of the fixing seat, and the fixing seat is correspondingly installed on the four sides of the top of the workbench.

[0011] Preferably, the slide forms a horizontal moving structure through a reciprocating screw rod and a transverse groove, and the suction pipes on the front and rear sides of the slide are arranged in an "L"-shaped structure, and the bottom opening of the suction pipe faces the cutting knife.

[0012] Preferably, the left end portion of the reciprocating screw rod is connected to the outside of the top frame, and a large gear is fixedly installed on the left end portion of the reciprocating screw rod, and a small gear is meshedly connected to the top of the large gear, and the small gear bearing is connected to the top of the top frame.

[0013] Preferably, the right side of the pinion shaft passes through the bearing and is connected to the collection box, and a fan is fixedly installed on the right side of the pinion shaft, and the fan is located inside the collection box, and the right side of the fan is separated from the internal space of the collection box by a partition net.

[0014] Preferably, a gear ring is fixedly mounted on the shaft of the suction pipe, and a torsion spring is installed at the connection between the suction pipe and the slide, and the top of the gear ring intermittently meshes with the convex tooth group, and the convex tooth group is evenly spaced at the bottom of the top frame.

[0015] Preferably, the fixing seat on the workbench is configured as a rectangular parallelepiped structure, and a positioning rod sliding through the fixing seat is provided with through holes at equal intervals, and an inward end portion of the positioning rod is configured as a "C"-shaped structure.

[0016] Preferably, an insertion rod is slidably connected through the fixing seat, and the insertion rod is configured as a comb-shaped structure, and a spring is installed between the insertion rod and the fixing seat, and the bottom of the spring is plug-connected with the through hole on the positioning rod.

[0017] Compared with the prior art, the V-groove cutting machine with a waste adsorption structure of the utility model has the following beneficial effects: when in use, the waste generated during the cutting process can be adsorbed and collected in a timely manner to avoid affecting the subsequent cutting work, and the positioning mechanism can be adaptively adjusted to facilitate cutting and grooving of circuit boards of different styles. The specific contents are as follows:

[0018] 1. Through the setting of the slide and the suction pipe, the waste generated can be adsorbed and collected in time while the V-groove cutting work is being carried out, so as to avoid accumulation on the work surface and affect the subsequent processing;

[0019] Furthermore, when the reciprocating screw rotates, the slide moves, thereby driving the cutting knife to move and cut the V-groove. When the reciprocating screw rotates, the large gear rotates synchronously, and when the large gear rotates, the small gear rotates. When the small gear rotates, the fan rotates rapidly, thereby generating suction inside the collecting box, and then the waste materials during cutting are adsorbed and collected in time through the suction pipe.

[0020] Furthermore, by setting the gear ring and the convex tooth group, when the slide moves, the gear ring can be driven to intermittently mesh with the convex tooth group, so that the gear ring drives the suction pipe to rotate, and the suction pipe will reverse the torsion spring after rotating. When the gear ring and the convex tooth group are misaligned, the torsion spring will drive the suction pipe to rotate, so that the suction pipe will swing, thereby improving the efficiency of waste adsorption and collection;

[0021] 2. Through the setting of the fixing seat and the positioning rod, the circuit board can be positioned according to the needs, so that the positioning rod can always fit the outer side of the circuit board, adapt to circuit boards of different shapes, and has high practicality;

[0022] Furthermore, by setting the plug rod and the spring, the position of the adjusted positioning rod can be locked. When the plug rod is pulled, the spring will be compressed, thereby separating the positioning rod from the through hole in the initial position. The position of the positioning rod can then be adjusted. After adjustment, the plug rod can be released, and the spring will drive it to connect with the through hole in the corresponding position.
