[0002] A circuit board can be called a printed wiring board or a printed circuit board, which plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. When producing a circuit board, an edge grinding machine is required to grind the burrs on the edge of the circuit board to make it have a good quality rate.

[0003] However, when cutting and grinding the circuit board, the circuit boards are usually stacked on a tray and moved from the tray to the conveyor roller of the edge grinding machine through an adsorption component, which takes a certain amount of time. When the number of circuit boards is less, the time required to move the circuit boards is longer. After all the circuit boards are moved, the operator still needs to reload the tray, which is not conducive to improving the feeding effect of the circuit board. Content of the Utility Model

[0004] The purpose of the utility model is to provide an edge grinding machine applied to double-sided multi-layer circuit boards to solve the above problems. The circuit board is placed on a bracket, and through a sliding mechanism, it can be moved towards the conveyor roller. When pulling the fixed frame, the moving base can be driven to separate from the limiting mechanism, thereby facilitating the operator to add and place the circuit board on the bracket.

[0005] The utility model realizes the above purpose through the following technical solutions. An edge grinding machine applied to double-sided multi-layer circuit boards includes an edge grinding machine body. A plurality of conveyor rollers are rotatably connected to the edge grinding machine body. A sliding mechanism is slidably installed on the edge grinding machine body. A limiting mechanism is fixed on the edge grinding machine body. A moving base is installed on the limiting mechanism. A support mechanism is fixedly installed at the top of the moving base. The support mechanism includes a fixed frame and a bracket. The fixed frame is fixedly connected to the top of the moving base.

[0008] Preferably, the length of the roller is less than the length of the connecting shaft, and the diameter of the connecting shaft is less than the diameter of the roller.

[0009] Preferably, the limiting mechanism includes a clamping plate and a limiting hole. A clamping plate is fixedly connected to the fixed frame, and a limiting hole is provided on the clamping plate. A positioning frame is fixedly installed on the edging machine body. The clamping plate is snap-connected with the positioning frame. A clamping groove is provided on the positioning frame, and a limiting rod is snap-mounted on the positioning frame.

[0010] Preferably, the part of the clamping plate in contact with the positioning frame is arranged in an inclined surface structure, and the two clamping plates are symmetrically arranged on the side wall of the fixed frame.

[0015] The beneficial effects of the present utility model are as follows: When the circuit board is conveyed to the conveying roller provided on the edging machine body, the circuit board can be first placed on the top of the bracket. A number of brackets are cooperatively connected through connecting rods, and the vertical rods fixed on the moving base support the brackets, so that the brackets support the circuit board more stably; Since a connecting shaft is fixed on the bracket and a roller is rotatably connected to the connecting shaft, when placing the circuit board, the circuit board contacts the roller, and then it rotates along the connecting shaft.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-7As shown in the figure, an edge grinding machine for double-sided multi-layer circuit boards includes an edge grinding machine body 1.

A support mechanism 6 is fixedly installed at the top of the moving base 5. The support mechanism 6 includes a fixed frame 601 and a bracket 602. The top of the moving base 5 is fixedly connected to the fixed frame 601. A plurality of brackets 602 are equidistantly and fixedly installed on the fixed frame 601. Adjacent two brackets 602 are fixedly connected by a connecting rod 606. A plurality of connecting shafts 603 are fixedly installed on the bracket 602. A roller 604 is rotatably connected to the connecting shaft 603. Two brackets 602 are fixedly connected with a vertical rod 605. The vertical rod 605 is fixedly connected to the moving base 5.

[0026] As a technical optimization scheme of the present utility model, the fixed frame 601 is located at one end of the moving base 5 away from the edge grinding machine body 1. The vertical rod 605 is arranged in an L-shaped structure. The arrangement of the vertical rod 605 can support the bracket 602, so that it is in a stable state.

[0027] As a technical optimization scheme of the present utility model, a plurality of the connecting shafts 603 and the rollers 604 are both arranged at equal intervals, and the diameter of the roller 604 is larger than the height of the bracket 602. When the circuit board is placed on the bracket 602, it contacts the roller 604, and thus the friction area between it and the bracket 602 can be reduced by the roller 604.

[0028] As a technical optimization scheme of the present utility model, the length of the roller 604 is less than the length of the connecting shaft 603, and the diameter of the connecting shaft 603 is less than the diameter of the roller 604. When the circuit board moves, the roller 604 can rotate along the connecting shaft 603, which is convenient for improving the moving effect of the circuit board.

[0029] As a technical optimization scheme of the present utility model, the limiting mechanism 3 includes a clamping plate 303 and a limiting hole 305. The clamping plate 303 is fixedly connected to the fixed frame 601. The clamping plate 303 is provided with the limiting hole 305. A positioning frame 301 is fixedly installed on the edge grinding machine body 1. The clamping plate 303 is snap-fitted with the positioning frame 301. The positioning frame 301 is provided with a clamping groove 304. A limiting rod 302 is snap-fitted on the positioning frame 301. The clamping plate 303 moves to the inside of the positioning frame 301 along with the moving base 5, and thus the moving base 5 can be limited.

[0030] As a technical optimization solution of the utility model, the contact portion between the clamping plate 303 and the positioning frame 301 is arranged in an inclined structure, and the two clamping plates 303 are symmetrically arranged on the side walls of the fixed frame 601. Through the clamping plate 303, the movable base 5 can be located between the two positioning frames 301.

[0031] As a technical optimization solution of the utility model, the diameter of the end of the limit rod 302 is equal to the diameter of the limit hole 305, and the limit rod 302 is snap-fitted with the clamping plate 303. When the limit rod 302 is inserted into the positioning frame 301, the clamping plate 303 and the movable base 5 can be limited by the limit rod 302.

[0032] As a technical optimization scheme of the utility model, the sliding mechanism 4 includes a motor 403 and a screw rod 404. The motor 403 is fixedly installed on the edge grinding machine body 1. The output end of the motor 403 is fixedly connected to a screw rod 404 through a coupling. Guide wheels 405 are fixedly installed on the two screw rods 404. Belts 406 are wrapped around the guide wheels 405. Slide plates 402 are threadedly connected to the screw rods 404. Slide grooves 401 are symmetrically provided on the edge grinding machine body 1. When the motor 403 is started, the screw rod 404 can drive the slide plate 402 to slide in the slide groove 401.

[0033] As a technical optimization solution of the utility model, a slide plate 402 is slidably arranged in the slide groove 401, and the screw rod 404 is rotatably connected to the edge grinding machine body 1. When the slide plate 402 slides from bottom to top, the circuit board placed on the bracket 602 can be removed, thereby facilitating the loading of the circuit board.

[0034] As a technical optimization solution of the utility model, the two screw rods 404 are symmetrically arranged, and the cross-section of the guide wheel 405 is arranged in an "I"-shaped structure. The guide wheel 405 drives the belt 406 to rotate, so that the screw rod 404 can rotate inside the edge grinding machine body 1.

[0035] When the utility model is in use, first, when the circuit board is conveyed onto the conveying roller 2 provided on the edge grinding machine body 1, the circuit board can be first placed on the top of the bracket 602. A plurality of brackets 602 are cooperatively connected through a connecting rod 606, and the vertical rod 605 fixed on the moving base 5 supports the bracket 602, so that the bracket 602 supports the circuit board more stably; since a coupling shaft 603 is fixed on the bracket 602, a roller 604 is rotatably connected to the coupling shaft 603. When the circuit board is placed, the circuit board contacts the roller 604 and thus rotates along the coupling shaft 603. The setting of the roller 604 can reduce the friction area between the circuit board and the bracket 602, which is conducive to preventing the circuit board at the bottom from being worn when the operator transports the circuit board; after the circuit board is placed on the bracket 602, the operator can push the fixing frame 601 installed at the top of the moving base 5 by hand. When the moving base 5 slides to the part between the two positioning frames 301, the clamping plates 303 fixed on both sides of the fixing frame 601 can be clamped to the position of the card slot 304 provided in the positioning frame 301. Since the limiting hole 305 is provided on the clamping plate 303, the limiting rod 302 is passed through the inner wall of the positioning frame 301 and clamped into the inside of the clamping plate 303, so that the limiting rod 302 limits the clamping plate 303, and thus the moving base 5 is in a stable state; then the control switch of the motor 403 is started. When the motor 403 is turned on, it drives a lead screw 404 to rotate, and thus the other lead screw 404 rotates along the inner wall of the edge grinding machine body 1 under the driving action of the guide wheel 405 and the belt 406. A slide plate 402 is threadedly connected to the lead screw 404. When the lead screw 404 rotates, it drives the slide plate 402 to move upward in the direction close to the motor 403. When the slide plate 402 slides to the gap between the brackets 602, it can lift the circuit board placed on the bracket 602, so that the circuit board moves in the direction close to the adsorption component on the edge grinding machine body 1, and the circuit board is conveyed to the edge grinding component through the conveying roller 2 for edge grinding. At the same time, the moving base 5 is pulled away, which is convenient for the operator to add circuit boards to the bracket 602 and is conducive to improving the feeding speed of the circuit board.
