Description

Technical Field

[0001] The utility model belongs to the technical field of PCB routing, and particularly relates to a pin pressing structure and a routing device. Background Art

[0002] A PCB routing machine is a machine used to cut a PCB connected by postage stamp holes, also called a PCB curve board cutting machine, a desktop curve board cutting machine, or a postage stamp hole PCB board cutting machine, which has the advantages of fast cutting speed and high cutting accuracy.

[0003] In the existing routing technology, several layers of PCBs need to be uniformly fixed by pins, that is, the PCBs are placed on a pin seat, and then the pins are passed through the PCBs and inserted into the pin seat, and the pins are knocked until the pins are firmly inserted into the pin seat before the routing operation on the PCBs can be carried out to ensure the accuracy of routing. However, a number of pins are required to position the PCBs, and the operator needs to knock each pin one by one until the pin is stably inserted into the pin seat. The operation is cumbersome and time-consuming, with a large amount of manual labor, increasing the routing time and greatly reducing the efficiency of pin pressing. Summary of the Utility Model

[0004] To solve the deficiencies of the existing technology, the utility model provides a pin pressing structure. Through the cooperative design of a pin pressing mechanism and a limiting mechanism, the limiting shell of the limiting mechanism is used to limit the edge of the PCB, and then the pin pressing mechanism moves downward towards the PCB, so that the pin pressing mechanism presses the pins until the pins are stably inserted and the PCB is positioned, ensuring the accuracy of the subsequent routing operation, thereby effectively simplifying the operation method, eliminating the need for manual intervention, shortening the operation time of pin pressing, and effectively improving the pin pressing efficiency. The utility model also provides a routing device, which adopts the design of the pin pressing structure, and improves the routing efficiency due to the shortening of the operation time of pin pressing.

[0005] The technical effects to be achieved by the utility model are realized through the following aspects:

[0006] In the first aspect, the utility model provides a pin pressing structure, which includes a lifting mechanism, a limiting mechanism, and a pin pressing mechanism.

[0008] In some implementations, the limiting shell includes a top plate and side plates, and the side plates are formed by extending from the edge of the top plate in the descending direction of the lifting mechanism; the limiting cavity is an area surrounded by the side plates and the top plate.

[0009] In some implementations, the limiting shell further includes a first limiting block, which is fixedly connected to one end of the side plate away from the top plate and protrudes towards the limiting cavity.

[0010] In some implementations, the first limiting block is arranged parallel to the top plate.

One end of the first pushing member is connected to the limiting shell, the other end of the first pushing member is connected to the first pin pressing member, and the first pin pressing member is movable within the limiting cavity.

[0012] In some implementations, the limiting mechanism further includes a limiting component, which is fixedly connected to one end of the side plate away from the top plate and protrudes towards the limiting cavity.

[0013] In some implementations, the limiting component includes a second pushing member and a second limiting block. One end of the second pushing member is connected to the side plate, and the other end of the second pushing member is connected to the second limiting block.

[0018] 1. The pin pressing structure provided by the present utility model, through the combined design of the pin pressing mechanism and the limiting mechanism, uses the limiting shell of the limiting mechanism to restrict the edge of the circuit board, and then moves downward toward the circuit board through the pin pressing mechanism, so that the pin pressing mechanism presses down on the pin until the pin is stably inserted and the circuit board is positioned, ensuring the accuracy of the subsequent routing operation, thus effectively simplifying the operation method, eliminating the need for manual intervention, shortening the operation time of pin pressing, and effectively improving the pin pressing efficiency.

[0030] To make the objectives, technical solutions and advantages of the implementation manners of the present utility model clearer, the technical solutions in the implementation manners of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the implementation manners of the present utility model. The described implementation manners are some but not all of the implementation manners of the present utility model.

[0031] Therefore, the following detailed description of the implementation manners of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected implementation manners of the present utility model. All other implementation manners obtained by those of ordinary skill in the art based on the implementation manners in the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0032] Embodiment 1:

[0033] Please refer to the attached Figure 1-2 , the pin pressing structure of the present utility model includes a lifting mechanism 1, a limiting mechanism 2 and a pin pressing mechanism 3. The lifting mechanism 1 is drivingly connected to the limiting mechanism 2, and the pin pressing mechanism 3 is movably connected within the limiting mechanism 2. Among them, the limiting mechanism 2 includes a limiting shell 21, and a limiting cavity 211 is provided inside the limiting shell 21; the outer wall of the upper end of the limiting shell 21 is drivingly connected to the lifting mechanism 1; the pin pressing mechanism 3 is arranged in the limiting cavity 211 and is connected to the inner wall of the limiting shell 21.

[0034] Specifically, the limiting shell 21 includes a top plate 212 and side plates 213. The side plates 213 extend from the edge of the top plate 212 in the descending direction of the lifting mechanism 1; the limiting cavity 211 is an area surrounded by the side plates 213 and the top plate 212. It can be understood that the lifting mechanism 1 is connected to the outer wall of the top plate 212, and the pin pressing mechanism 3 is connected to the inner wall of the top plate 212.

[0035] Among them, the lifting mechanism 1 is used to drive the limiting mechanism 2 to approach or move away from the circuit board, that is, to drive the limiting mechanism 2 to perform lifting operations.

[0036] The limiting mechanism 2 is used to limit the edge of the circuit board, that is, the limiting mechanism 2 descends until the circuit board is embedded in the limiting cavity 211, so that the side plates 213 of the limiting shell 21 frame the edge of the circuit board.

[0037] The pin pressing mechanism 3 is used to press the pin into the pin seat to ensure the stability of the pin fixing the circuit board; that is, when the circuit board is embedded in the limiting cavity 211, the pin pressing mechanism 3 presses down until the pin is stably embedded in the pin seat.

[0038] In this embodiment, the operation process of the pin pressing structure 6 is as follows: The circuit board to be routed is placed on the pin seat, and the pin is inserted through the circuit board and inserted onto the pin seat. Secondly, the lifting mechanism 1 is started to drive the limiting mechanism 2 to move towards the circuit board until the circuit board is embedded in the limiting cavity 211, and the side plate 213 of the limiting shell 21 frames the edge of the circuit board. Subsequently, the pin pressing mechanism 3 is started to press down until the pin is stably embedded in the pin seat, so as to complete the batch pressing of the pins, ensure the stability of the pins inserted into the pin seat, and further ensure the stable fixation of the circuit board. Finally, the pin pressing mechanism 3 rises to the initial position, that is, close to the top plate 212, and the lifting mechanism 1 is started to drive the limiting mechanism 2 to rise to the initial position, that is, a position away from the circuit board, waiting for the operation of pressing the next batch of pins into the pin seat. Among them, the operation process of each mechanism is realized by using the existing PLC program control.

[0039] Through the above pin pressing structure 6, the limiting shell 21 of the limiting mechanism 2 is used to limit the edge of the circuit board, so as to ensure the stacking stability of the circuit board during the pin pressing process. Then, the pin pressing mechanism 3 moves downward towards the circuit board, so that the pin pressing mechanism 3 performs a pressing operation on the pin until the pin is stably inserted and then the circuit board is positioned, realizing the batch pressing of the pins. The operation is convenient and fast, without manual intervention, shortening the operation time of pin pressing, effectively improving the pin pressing efficiency, and further ensuring the accuracy of the subsequent routing operation.

[0040] It can be understood that the pin pressing mechanism 3 includes a first pin pressing member 31 and a first pushing member 32. One end of the first pushing member 32 is connected to the limiting shell 21, and the other end of the first pushing member 32 is connected to the first pin pressing member 31. The first pin pressing member 31 moves in the limiting cavity 211. Among them, the first pushing member 32 can be realized by using a pushing cylinder in the existing technology. Through the above setting, the operation process of the pin pressing mechanism 3 is: starting the first pushing member 32 to push the first pin pressing member 31 towards the pin until the first pin pressing member 31 presses the pin into the pin seat, realizing the stable fixation of several layers of circuit boards by the pin. The operation is simple, practical, convenient for batch pressing of pins, and the operation is fast.

[0041] In some embodiments, please refer to the attached Figure 3-4 , the limiting shell 21 further includes a first limiting block 214. The first limiting block 214 is fixedly connected to one end of the side plate 213 away from the top plate 212 and protrudes towards the limiting cavity 211. Preferably, the first limiting block 214 is arranged parallel to the top plate 212. By setting the first limiting block 214 to limit the edge of the circuit board, compared with the method of using the side plate 213 to limit the edge of the circuit board, the thickness of the side plate 213 can be designed to be thin and light. On the premise of ensuring the edge limitation of the circuit board, the overall weight can also be made lighter, effectively reducing the energy consumption.

[0042] Example 2:

[0043] The difference between this embodiment and Embodiment 1 is that, referring to the attached Figure 5-7 , the limit mechanism 2 of this embodiment further includes a limit component 22, and the limit component 22 is fixedly connected to one end of the side plate 213 away from the top plate 212 and is convexly arranged towards the limit cavity 211. Specifically, the limit component 22 includes a second pushing member 221 and a second limit block 222. One end of the second pushing member 221 is connected to the side plate 213, and the other end of the second pushing member 221 is connected to the second limit block 222. Among them, the second pushing member 221 can be realized by using an existing pushing cylinder.

[0044] The limit component 22 in this embodiment is used to limit the edge of the circuit board and can be applied to the limitation of circuit boards of different sizes. Its operation process is as follows: when the limit shell 21 descends through the lifting mechanism 1 until the circuit board is embedded in the limit cavity 211, start the second pushing member 221 to push the second limit block 222 towards the edge of the circuit board until the edges of the circuit board are all restricted by the second limit block 222, and then the pin pressing mechanism 3 performs the pin pressing action. Through this setting, circuit boards of different sizes can be dealt with, ensuring the stability of the circuit board during the pin pressing process and realizing the smoothness of the pin pressing.

[0045] In some embodiments, the pin pressing mechanism 3 includes a first pin pressing component, a second pin pressing component 3B, and a third pin pressing component 3C. The second pin pressing component 3B is arranged in parallel on both sides of the first pin pressing component, and the third pin pressing component 3C is arranged in parallel on both sides of the second pin pressing component 3B.

[0046] Specifically, the structures of the first pin pressing component, the second pin pressing component 3B, and the third pin pressing component 3C are the same; the first pin pressing component includes a second pin pressing member 3A1 and a third pushing member 3A2. One end of the third pushing member 3A2 is connected to the limit shell 21, and the other end of the third pushing member 3A2 is connected to the second pin pressing member 3A1. The second pin pressing member 3A1 moves in the limit cavity 211. Among them, the third pushing member 3A2 can be realized by using an existing pushing cylinder.

[0047] In the pin pressing mechanism 3 of this embodiment, the first pin pressing component, the second pin pressing component 3B, or the third pin pressing component 3C can be pressed down individually or in cooperation according to the size of the circuit board. When dealing with a small-sized circuit board, only the first pin pressing component needs to be controlled to press the pin into the board; when dealing with a larger-sized circuit board, the first pin pressing component and the second pin pressing component 3B need to be controlled to operate synchronously to perform the pressing operation; when dealing with an even larger-sized circuit board, the first pin pressing component, the second pin pressing component 3B, and the third pin pressing component 3C need to be controlled to operate synchronously to press the pin into the board. Through this setting, it can be applicable to circuit boards of various different sizes, with a wide application range and flexible and convenient operation.

[0048] Embodiment 3:

[0049] Based on the above embodiment, in this embodiment, please refer to the attached Figure 8 , a routing device is provided, which includes a machine case 4, a routing table 5, and the above-mentioned pin pressing structure 6. The pin pressing structure 6 is fixedly connected to the machine case 4 and is correspondingly arranged relative to the routing table 5. Through this setting, with the design of the pin pressing structure 6, the circuit board located on the routing table 5 is restricted, and then the pin is pressed into the pin seat. After the pin pressing structure 6 returns to its initial position, the routing operation is performed on the circuit board. Since the operation time of pressing the pin is shortened, the routing efficiency is improved.
