Description

TECHNICAL FIELD

[0002] As an indispensable basic component in modern electronic equipment, the manufacturing process of the circuit board contains multiple key links. At present, for the splitting work of the assembled circuit board, the traditional splitting process is generally adopted, that is, the operator manually places and positions the one-side margin of the circuit board mother board on the workbench of the splitting machine, then starts the machine, and cuts the one-side margin.

[0031] Embodiment:

[0032] Please refer to Figure 1 - Figure 7 The present application provides a technical solution: a circuit board splitting processing equipment using double-blade synchronous cutting, comprising:

[0033] The base frame 1 is provided with a mounting groove 11 for realizing the circuit board splitting work, and the top end of the mounting groove 11 is provided with a position adjusting unit 2;

[0034] The conveying unit 3 is arranged at the bottom end of the mounting groove 11, and is used for realizing the conveying work of the circuit board after the splitting is completed;

[0035] The cutting knife 4 is provided with two, and the two cutting knives 4 are connected with the position adjusting unit 2 through the support frames 41 rotatably connected therewith;

[0036] The inside of the mounting groove 11 is further provided with two partitions 12, and the positions of the circuit board during preparation are adjusted through the arrangement of the partitions 12, so as to ensure the accuracy of the cutting allowance.

[0037] The two partitions 12 are arranged symmetrically left and right according to the conveying unit 3, and the mounting groove 11 is divided into a conveying section 111 and two blanking sections 112 through the two partitions 12, wherein the two blanking sections 112 are arranged symmetrically according to the conveying section 111.

[0038] The separator 12 comprises two adjusting plates 121 and a cutting plate 122, wherein the cutting plate 122 is located between the two adjusting plates 121.

[0039] The two adjusting plates 121 at the rear are each provided with a guide 123, which comprises a U-shaped frame 1231 arranged above the adjusting plate 121, the two U-shaped frames 1231 are opposite at the opening positions, and a guide block 1232 is arranged inside the two U-shaped frames 1231.

[0040] The two guide blocks 1232 are arranged in an inclined manner, that is, the width of the guide block 1232 gradually increases from the side away from the conveyor set 3 to the side close to the conveyor set 3, and a plurality of rotating rollers 1233 are arranged on the inclined side wall of the guide block 1232.

[0041] The two adjusting plates 121 at the front are each provided with a cleaning block 1211, and the side wall close to the two cleaning blocks 1211 is each provided with a plurality of arc-shaped grooves 1212 in the front-rear direction.

[0042] The top end of the cutting plate 122 is arranged in a corresponding beveled shape corresponding to the cutting edge of the cutting knife 4, and a guide inclined table 1221 is arranged on the two side walls of the cutting plate 122, wherein the guide inclined table 1221 away from the conveyor set 3 is provided with a limiting frame 1222 for limiting the circuit board.

[0043] The end surface of the support frame 41 is provided with a matching groove, the cutting knife 4 is threadedly connected with the matching groove through a locking block 42 arranged at the center of the cutting knife 4, and the support frame 41 is further provided with a blocking plate 43 on the front and rear sides of the cutting knife 4.

[0044] Specifically, the placement of the circuit board:

[0045] The circuit board is an indispensable basic component in modern electronic equipment, and its manufacturing process includes multiple key links. At present, for the splitting of the circuit board, the traditional splitting process is generally used, that is, the operator manually places and positions the excess amount of one side of the circuit board mother board on the workbench of the splitting machine, then starts the machine, and then cuts the excess amount of one side through the cutting knife 4. After the cutting of one side is completed, the operator needs to manually take the circuit board mother board from the workbench, turn it over, align the excess amount of the other side with the cutting position, and repeat the above positioning and cutting process until the entire splitting operation is completed.

[0046] However, the existing circuit board splitting process has many bottlenecks due to its high dependence on manual operation. In the entire splitting process, from the loading and unloading of the circuit board to the repeated flipping, the operator needs to be involved throughout the process. This not only significantly increases the labor cost and the labor intensity of the operator, but also requires the operator to continuously provide auxiliary support to maintain the stability of the workpiece during the cutting process, thereby ensuring the cutting accuracy. This mode of relying on manual single-sided and piece-by-piece cutting directly leads to low production efficiency. Based on this, the circuit board splitting processing equipment using the double-blade synchronous cutting technology is provided with a partition 12. Through the configuration of the partition 12, batch and synchronous clamping and processing of multiple circuit board motherboards are realized. This optimization not only innovates the cutting method, greatly improves the processing efficiency and overall work efficiency per unit time, but more importantly, the partition 12 plays a key role in positioning and guiding during the placement and clamping of the circuit board motherboard. It can effectively adjust and fix the relative positions of each circuit board in the mounting groove 11, thereby providing a high-precision reference for the subsequent double-blade synchronous cutting process, ensuring the accuracy and consistency of the cutting knife 4 when cutting the two-side margin of the circuit board, and ultimately guaranteeing the splitting quality and product yield.

[0047] Specifically, the two rear adjusting plates 121 are respectively provided with an open U-shaped frame 1231, which together constitutes the circuit board introduction channel. In order to optimize the feeding process, the working position of the operator is also adjusted accordingly. Instead of fine positioning opposite the dividing machine, the operator can stand at the side of the device and operate at the position of the U-shaped frame 1231. When the operator puts the circuit board to be cut along the two U-shaped frames 1231, the side close to each other of the two U-shaped frames 1231 is provided with a guide block 1232. The two guide blocks 1232 are designed to be inclined, that is, the width gradually increases from the side away from the conveyor set 3 to the side close to the conveyor set 3. At the entrance, the width between the guide blocks 1232 is small, forming a horn-shaped guide area, so that the circuit board can enter very smoothly without the operator needing to make preliminary position adjustment, greatly reducing the difficulty and operation strength of feeding. As the circuit board is continuously pushed into the U-shaped frame 1231, its two ends will contact the inclined side wall of the guide block 1232. Under the guidance of the inclined surface, the circuit board will gradually move to the center position until accurate center symmetric positioning is achieved. In order to make the guiding process smoother, a plurality of rotating rollers 1233 are rotatably arranged on the inclined side wall of the guide block 1232. The introduction of these rotating rollers 1233 changes the traditional sliding friction between the circuit board and the guide block 1232 to rolling friction. This change not only effectively reduces the friction and the risk of scratching the surface of the circuit board, but also significantly improves the smoothness of the circuit board during placement through the coordinated action of multiple rotating rollers 1233, fundamentally avoiding the possibility of jamming due to excessive friction. When a circuit board is placed in position, the operator can directly put in the next one. The circuit board placed later will push the previous one to move forward. In this way, the operator can quickly and continuously complete the stacking and placement of multiple circuit boards, until the front end face of the frontmost circuit board is close to the side wall of the preset cleaning block 1211. At this time, the placement and positioning of the entire circuit board are efficiently and accurately completed, fully preparing for the subsequent automatic cutting process.

[0048] It should be noted that the guide inclined table 1221 away from the conveyor set 3 is provided with a limiting frame 1222, the two ends of the limiting frame 1222 are respectively arranged in the U-shaped frame 1231 and the side wall of the cleaning block 1211 through the top pressure spring sliding, and the rear end of the limiting frame 1222 is provided with a chamfer, in the initial state, due to the force of the top pressure spring, the limiting frame 1222 is slightly lower than the U-shaped frame 1231, when the circuit board enters the inside of the limiting frame 1222 along the guide block 1232, the circuit board is pushed upward by the upper end face of the limiting frame 1222, so that the limiting frame 1222 is moved from the position slightly lower than the U-shaped frame 1231 to the position flat with the U-shaped frame 1231, through the setting of the limiting frame 1222 and the top pressure spring, the self-adaptive abutting work of the two ends of the circuit board before cutting work is realized, and then the stability of the position of the circuit board after placement is ensured.

[0049] The board splitting work of the circuit board:

[0050] In the existing cutting process of the circuit board, the consistency and stability in the cutting process are poor due to the need for manual assistance, manual positioning and turning are difficult to ensure the high consistency of each operation, and positioning deviation is easy to be caused by human factors, which affects the cutting precision and causes the uneven quality of the edges of the circuit board, based on this, the circuit board splitting processing equipment adopting double-blade synchronous cutting has completed the position adjustment of the circuit board when placing the circuit board, and then in the subsequent cutting work, the cutting work of the two sides of the circuit board is realized through the movement of the two cutting knives 4.

[0051] Specifically, the two cutting knives 4 are in the initial state on the front side adjusting plate 121, avoiding blocking the circuit board during the placement process, after a batch of circuit boards are placed, the positioner set 2 is started, and the two cutting knives 4 on both sides are moved synchronously by the positioner set 2, when the cutting knives 4 move to the cutting plate 122, the cutting work of the excess amount of the circuit board is realized through the cooperation of the blade edge and the inclined port of the cutting plate 122.

[0052] The circuit board after the excess amount cutting falls to the conveyor set 3 below naturally under the action of gravity, and then the conveyor set 3 is started, and the circuit board after cutting is moved to the next processing area by the conveyor set 3.

[0053] It should be noted that the installation groove 11 is divided into a conveying section 111 and two blanking sections 112 by two partitions 12, both side walls of the cutting plate 122 are provided with guide ramps 1221, after the cutting knife 4 completes the cutting work, the circuit board falls into the conveyor set 3 under the guidance of the guide ramps 1221 in the conveying section 111, so as not to fall too scattered, and the excess on the circuit board is quickly reset by the top pressing spring on both sides due to the lack of support, and the excess is quickly moved downward, thereby making the excess after cutting naturally fall under the guidance of the blanking guide ramp 1221, which physically separates the circuit board and the excess, without the need for sorting, further improving the efficiency of the circuit board splitting work.

[0054] The two front adjusting plates 121 are provided with cleaning blocks 1211, and the side wall close to the two cleaning blocks 1211 is provided with a plurality of arc-shaped grooves 1212, through the arrangement of the arc-shaped grooves 1212, a small amount of debris attached to the surface of the cutting knife 4 is cleaned during the resetting process of the cutting knife 4 through the contact and cooperation of the arc-shaped grooves 1212, the small amount of debris cleaned falls downward along the arc-shaped grooves 1212, through the arrangement of the arc-shaped grooves 1212, the cleanliness of the cutting edge of the cutting knife 4 during each cutting process is ensured, thereby improving the flatness of the cutting section, and further improving the quality of the circuit board splitting from the side.

[0055] Finally, after completing the splitting work of a batch of circuit boards, the above steps are repeated, and the splitting work of the next batch of circuit boards can be realized.

[0056] It is worth emphasizing that the circuit board splitting processing equipment with double-blade synchronous cutting mainly has the following advantages:

[0057] The advantage one is that the multiple circuit board motherboards are clamped and processed in batches and synchronously through the divider 12, the processing efficiency and the overall working efficiency in a unit of time are greatly improved, during the equipment working process, the operator puts the circuit boards to be cut into the two U-shaped frames 1231, the side close to each other of the two U-shaped frames 1231 is provided with a guide block 1232, the width of the guide block 1232 gradually increases from the side away from the conveyor set 3 to the side close to the conveyor set 3, a horn-shaped guide area is formed, the circuit board can smoothly enter without fine alignment at the entrance, then gradually moves to the center under the guidance of the inclined side wall of the guide block 1232, until the accurate center symmetric positioning is realized, in addition, a plurality of rotating rollers 1233 are rotatably arranged on the inclined side wall of the guide block 1232, the sliding friction is changed into the rolling friction, the friction is effectively reduced, the circuit board surface scratching and jamming problems are avoided, the operator can continuously stack and place multiple circuit boards, until the front end face of the frontmost circuit board is close to the side wall of the preset cleaning block 1211, so that the placement and accurate positioning of the whole batch of circuit boards are efficiently completed, and a high-precision reference is laid for the subsequent automatic cutting process.

[0058] The advantage two is that the limiting frame 1222 is arranged on the guide inclined table 1221 away from the conveyor set 3, the two ends of the limiting frame 1222 are slidably arranged on the side walls of the U-shaped frame 1231 and the cleaning block 1211 through the top pressure spring, and a chamfer is formed at the rear end thereof, in the initial state, due to the force of the top pressure spring, the limiting frame 1222 is slightly lower than the U-shaped frame 1231, when the circuit board enters the inside of the limiting frame 1222 along the guide block 1232, the upper end face of the circuit board pushes and abuts against the limiting frame 1222 upwards, so that the limiting frame 1222 moves from the position slightly lower than the U-shaped frame 1231 to the position flat with the U-shaped frame 1231, in this process, the top pressure spring continuously provides the reverse pressure, and the two ends of the circuit board are adaptively abutted, so that the position of the circuit board after the placement is firm and stable, and a reliable workpiece fixing guarantee is provided for the subsequent double-blade synchronous cutting.

[0059] Advantage three, the device completes the cutting of the excess of the circuit board on both sides at one time through the synchronous movement of the cutting knives 4 on both sides, which not only significantly improves the cutting efficiency, but also ensures the consistency and edge flatness of the cutting. The two cutting knives 4 are initially located on the front adjusting plate 121 to avoid blocking the placement process of the circuit board. After a batch of circuit boards are placed and positioned, the positioning machine set 2 is started to synchronously drive the cutting knives 4 on both sides to move. When the cutting knives 4 move to the cutting plate 122, the synchronous cutting of the excess of the circuit boards is realized through the cooperation of the cutting edges and the inclined openings of the cutting plate 122. After the cutting is completed, the circuit boards naturally fall onto the conveyor set 3 below under the action of gravity, and then the conveyor set 3 is started to convey the cut circuit boards to the next processing area. This double-edge synchronous cutting mode not only greatly shortens the time of single board separation operation, but also effectively avoids the positioning error caused by manual turning, thereby ensuring the high quality and consistency of the cutting edge.

[0060] Advantage four, the device realizes the automatic cleaning of the cutting edge and the automatic sorting of the circuit board and the excess through the design of the arc-shaped grooves 1212 of the cleaning blocks 1211 and the physical separation of the material falling section 112 and the conveying section 111, which not only improves the cutting quality, but also further reduces the frequency and cost of manual sorting and equipment maintenance. The two adjusting plates 121 in front are each provided with a cleaning block 1211, and the side wall close to the two cleaning blocks 1211 is provided with a plurality of arc-shaped grooves 1212. During the cutting and resetting of the cutting knives 4, the cutting edge is in contact with the arc-shaped grooves 1212, and a small amount of debris attached to the surface of the cutting knives 4 is automatically scraped off and falls downward along the arc-shaped grooves 1212, thereby ensuring the cleanliness of the cutting edge during each cutting process of the cutting knives 4 and improving the flatness of the cutting section. In addition, the installation groove 11 is divided into a conveying section 111 and two material falling sections 112 by two partition pieces 12. After cutting is completed, the circuit board is guided to fall onto the conveyor set 3 by the guide inclined table 1221 in the conveying section 111, while the excess is moved downward under the action of the rapid resetting of the top pressure spring and finally falls naturally through the material falling guide inclined table 1221. In this way, the circuit board and the excess are physically and automatically separated, without manual sorting, thereby further improving the efficiency and automation level of the overall board separation work.
