Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a circuit board feeding and gripping device. Background Technology

[0002] In circuit board production, a gripping mechanism is generally used to grip and load the circuit boards during the loading process. The gripping mechanism typically uses a suction cup to adhere to the circuit board and then move it. However, current gripping mechanisms are generally fixed in place. While they can effectively grip circuit boards of a certain size, they cannot adjust the suction cup when gripping longer circuit boards. When the circuit board has a large span, the gripping effect is limited, and there is a possibility of it falling. Therefore, a circuit board loading gripping device is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a circuit board feeding and gripping device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a circuit board loading and gripping device, comprising a gantry frame, a horizontal moving device, and a moving lifting device;

[0005] The top of the gantry is equipped with a horizontally arranged horizontal moving device, and the outside of the horizontal moving device is equipped with a vertically arranged moving lifting device. The bottom of the moving lifting device is equipped with an adjustment mechanism, and the outside of the adjustment mechanism is equipped with multiple gripping mechanisms.

[0006] The adjustment mechanism includes a mounting frame, a dual-output shaft motor, and a threaded shaft. The top of the mounting frame is fixedly connected to the mobile lifting device. The dual-output shaft motor is fixedly connected inside the mounting frame. The two main shafts of the dual-output shaft motor are fixedly connected to the threaded shaft. A threaded sleeve is screwed onto the outside of the threaded shaft. A moving rod is fixedly connected to the other end of the threaded sleeve. The outside of the moving rod is slidably connected to the mounting frame. Multiple gripping mechanisms are installed on the outside of the moving rod.

[0007] Furthermore, there are two sets of threaded shafts, with the outer threads of the two side threaded shafts arranged in opposite directions.

[0008] Furthermore, a connecting plate is fixedly connected to the outer side of the threaded sleeve, and a guide sleeve is fixedly connected to the other end of the connecting plate. A guide rod is slidably connected to the inner side of the guide sleeve, and both ends of the guide rod are fixedly connected to the mounting frame.

[0009] In circuit board production, a gripping mechanism is typically used to pick up and load the circuit boards. This mechanism usually employs suction cups to adhere to the board and then move it. However, current gripping mechanisms are generally fixed in place. While effective for gripping boards of a single size, they cannot adjust for longer boards, limiting gripping effectiveness and increasing the risk of boards falling. In this new design, a dual-shaft motor drives a threaded shaft, which in turn moves a threaded sleeve. This sleeve then moves a moving rod to both sides, extending the gripping range and ensuring stable gripping of the board from both sides. This effectively prevents boards from falling and allows for gripping boards of varying lengths, expanding its application range.

[0010] Furthermore, the gripping mechanism includes a connector, an aluminum alloy plate, and a buffer pad. The inner side of the connector is detachably connected to the adjustment mechanism. An aluminum alloy plate is fixedly connected to the bottom of the connector. A hollow frame is fixedly connected to the bottom of the aluminum alloy plate. Multiple suction heads are installed on the side of the hollow frame. A buffer pad is fixedly connected to the bottom of the hollow frame.

[0011] Furthermore, the bottom of the cushioning pad has a through hole, and the cushioning pad is made of rubber sheet.

[0012] The bottom of the hollow frame is made of a cushioning pad with elastic rubber sheet, which can stably contact the surface of the material plate to achieve effective adsorption. The air suction head is connected to an external air pump, which can ensure that the air inside the hollow frame is extracted and negative pressure is formed to ensure that the cushioning pad stably grips the material plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When this utility model is in use, the dual-output shaft motor is started to move the threaded shaft, which in turn moves the threaded sleeve. At this time, the threaded sleeve can move the moving rod to both sides, which can extend the distance of the gripping mechanism and ensure that the gripping mechanism can grip both sides of the material plate, ensuring stable gripping of the material plate and effectively preventing the material plate from falling. This setting can grip material plates of different lengths, expanding the scope of application.

[0015] 2. When the threaded sleeve moves, the connecting plate above the threaded sleeve drives the guide sleeve to move. The guide sleeve slides outside the guide rod, which can guide the threaded sleeve and prevent the threaded sleeve from rotating on its own.

[0016] The bottom of the hollow frame is made of a cushioning pad with elastic rubber sheet, which can stably contact the surface of the material plate to achieve effective adsorption. The air suction head is connected to an external air pump, which can ensure that the air inside the hollow frame is extracted and negative pressure is formed to ensure that the cushioning pad stably grips the material plate.

[0017] Since the connector and the moving rod are detachably connected, the connector and the moving rod can be matched at different positions to grip material plates of different lengths. The suction heads are set in multiple groups, so even if one group of suction heads fails, the other suction heads can still effectively grip the material. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1 and Figure 2 This utility model provides a technical solution:

[0023] A circuit board loading and gripping device includes a gantry frame 1, a horizontal moving device 2, and a moving lifting device 3;

[0024] The top of the gantry frame 1 is equipped with a horizontally arranged horizontal moving device 2, the outside of the horizontal moving device 2 is equipped with a vertically arranged moving lifting device 3, and the bottom of the moving lifting device 3 is equipped with an adjustment mechanism 4. Multiple gripping mechanisms 5 are installed on the outside of the adjustment mechanism 4.

[0025] The aforementioned adjustment mechanism 4 includes a mounting frame 401, a dual-axis motor 402, and a threaded shaft 403. The top of the mounting frame 401 is fixedly connected to the mobile lifting device 3. The dual-axis motor 402 is fixedly connected inside the mounting frame 401. The two main shaft ends of the dual-axis motor 402 are fixedly connected to the threaded shaft 403. The outer side of the threaded shaft 403 is screwed with a threaded sleeve 404. The other end of the threaded sleeve 404 is fixedly connected to a moving rod 405. The outer side of the moving rod 405 is slidably connected to the mounting frame 401. Multiple gripping mechanisms 5 are installed on the outer side of the moving rod 405.

[0026] There are two sets of the aforementioned threaded shafts 403, and the outer threads of the aforementioned threaded shafts 403 on both sides are arranged in opposite directions.

[0027] A connecting plate 406 is fixedly connected to the outer side of the threaded sleeve 404, and a guide sleeve 407 is fixedly connected to the other end of the connecting plate 406. A guide rod 408 is slidably connected to the inner side of the guide sleeve 407, and both ends of the guide rod 408 are fixedly connected to the mounting frame 401.

[0028] In circuit board production, a gripping mechanism is typically used to pick up and load the circuit boards. This mechanism usually employs a suction cup to adhere to the board and then move it. However, current gripping mechanisms are generally fixed, which is effective for gripping boards of a single size. When gripping longer boards, the suction cup cannot be adjusted, and the gripping effect is limited when the board span is large, with the possibility of it falling. In this solution, a dual-shaft motor 402 is activated, moving the threaded shaft 403. The threaded shaft 403 then moves the threaded sleeve 404, which in turn moves the moving rod 405 to both sides. This extends the gripping mechanism 5's reach, ensuring it can grip both sides of the board, guaranteeing stable gripping and effectively preventing the board from falling. This design allows for gripping boards of different lengths, expanding its application range.

[0029] In this embodiment, when the threaded sleeve 404 moves, the connecting plate 406 above the threaded sleeve 404 drives the guide sleeve 407 to move. The guide sleeve 407 slides outside the guide rod 408, which can guide the threaded sleeve 404 and prevent the threaded sleeve 404 from rotating on its own.

[0030] Since the threads on the outer side of the threaded shaft 403 are arranged in opposite directions, the rotation of the threaded shaft 403 can drive the threaded sleeve 404 to move towards or away from each other.

[0031] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2Specifically, the gripping mechanism 5 includes a connector 501, an aluminum alloy plate 502, and a buffer pad 503. The inner side of the connector 501 is detachably connected to the adjustment mechanism 4. The bottom of the connector 501 is fixedly connected to the aluminum alloy plate 502. The bottom of the aluminum alloy plate 502 is fixedly connected to a hollow frame 504. Multiple suction heads 505 are installed on the side of the hollow frame 504. The bottom of the hollow frame 504 is fixedly connected to the buffer pad 503.

[0032] The bottom of the aforementioned buffer pad 503 is provided with a through hole, and the aforementioned buffer pad 503 is made of rubber sheet.

[0033] The bottom of the hollow frame 504 is made of a buffer pad 503 with elastic rubber sheet, which can stably contact the surface of the material plate to achieve effective adsorption. The suction head 505 is connected to an external air pump, which can ensure that the air inside the hollow frame 504 is extracted and a negative pressure is formed. The top of the buffer pad 503 is connected to the hollow frame 504, which can extract the air inside the buffer pad 503 to ensure that the buffer pad 503 stably grips the material plate.

[0034] In this embodiment, since the connector 501 and the moving rod 405 are detachably connected, the connector 501 and the moving rod 405 can cooperate at different positions to grip material plates of different lengths. The suction heads 505 are set in multiple groups, so even if one group of suction heads 505 fails, the other suction heads 505 can still effectively grip the material.
