Technical Field

[0001] The utility model belongs to the technical field of clamp mechanisms, and in particular relates to a rivet taking and placing mechanism. Background Art

[0002] In the process of printed PCB circuit board processing, how to quickly replace the printed PCB circuit board is a technical problem that needs to be solved urgently. At present, the processing technology of printed PCB circuit boards requires frequent replacement and fixation of printed PCB circuit boards, and most manufacturers usually replace and fix printed PCB circuit boards through manual operation. Such a process makes the operation of the staff complicated and inefficient, and greatly prolongs the standby time of the equipment. Utility Model Content

[0003] In order to solve the above technical problems, the utility model discloses a rivet picking and placing mechanism, which can quickly lock the printed PCB circuit board in the processing position and can quickly release the printed PCB circuit board from the processing position, thereby greatly increasing the efficiency of replacing the printed PCB circuit board and effectively reducing the equipment standby time.

[0004] The specific technical solution of the utility model is as follows:

[0005] A rivet taking and placing mechanism, comprising:

[0006] A fixing seat, wherein the fixing seat is provided with an opening, wherein a mounting portion is provided inside the fixing seat, wherein a locking slider which moves along its radial direction is provided on the mounting portion, and wherein the locking slider is provided with an oblique hole; and

[0007] The driving mechanism has an active end which is slidably connected to the locking slider via an inclined hole, and the active end of the driving mechanism moves axially relative to the fixing seat to drive the locking slider to move radially relative to the fixing seat.

[0008] The printed PCB circuit board comprises a board body and a base, the rivets are connected to the bottom surface of the base, the board body is positioned and fixed on the base by pins, and is connected to the bottom of the base by the rivets. At present, printed PCB circuit boards are generally completed through manual single-chip operations, so the degree of automation is low and the process efficiency is low. Therefore, in this embodiment, the board body is set on the base, and the base is fixed at the processing position by rivets, so that the board body can be efficiently processed at the determined processing position. After the processing is completed, the rivets are quickly released, so that the base and the board body are synchronously moved away from the processing position, and a rivet pick-up and release mechanism is configured at the processing position. By driving the rivet pick-up and release mechanism, the replacement or processing of the printed PCB circuit board can be realized; therefore, when it is necessary to process the printed PCB circuit board, the driving mechanism is used to drive the locking slider to move radially along the fixed seat to grab the rivets, so that the printed PCB circuit board and the working position are relatively fixed. When the printed PCB circuit board needs to be replaced, the rivets are released from the rivet pick-up and release mechanism in the reverse step of the above method, and the printed PCB circuit board can be removed to quickly replace the next printed PCB circuit board to be processed, thereby effectively improving the efficiency of replacing the printed PCB circuit board.

[0009] Preferably, two opposite locking sliders are arranged in the fixing seat, and the pull nail is clamped or released through the relative movement of the two locking sliders;

[0010] The active end of the driving mechanism is configured as a double-linked oblique guide column, and the double-linked oblique guide column is slidably matched with the oblique holes provided on the two locking slide blocks at the same time.

[0011] The double-linked oblique guide column can drive the two locking slide blocks to move synchronously, thereby meeting the clamping requirements for the rivet. The structure is simple and easy to implement.

[0012] Preferably, the driving mechanism comprises a driving piston, and the driving piston is provided with an annular groove;

[0013] The double-linked oblique guide column is provided with a hook matched with the annular groove, and the hook and the annular groove are slidably connected.

[0015] Preferably, the distance between the two inclined holes gradually decreases from the direction close to the opening to the direction away from the opening.

[0016] There is a sliding fit between the double-linked inclined guide column and the inclined hole. Since there is a gradual change in the distance between the two inclined holes, the double-linked inclined guide column and the inside of the inclined hole can come into contact during the movement of the double-linked inclined guide column. The force generated by the above contact drives the locking slider to move, thereby achieving locking and release.

[0017] Preferably, the mounting portion is configured as a positioning pressure plate, and the active end of the driving mechanism passes through the positioning pressure plate and is connected to the locking slider;

[0018] Wherein, a plurality of balls are arranged between the positioning pressure plate and the locking slider.

[0022] Preferably, a mounting groove is provided at the end of the locking slider, and one end of the elastic member is disposed in the mounting groove.

[0023] In addition to providing assembly conditions for the elastic member, the mounting groove also provides an assembly limit for the elastic member, so that the elastic member can only deform along its axial direction, thereby better meeting the requirements for clamping the rivet.

[0024] Preferably, a positioning portion is provided extending from the opening toward the inner side of the fixing seat, for limiting the radial displacement of the locking slider;

[0025] The locking slide block is provided with a step portion that cooperates with the positioning portion.

[0027] Preferably, the fixing seat comprises:

[0028] The first seat body and the second seat body are detachably connected, and a component accommodating space is formed between the first seat body and the second seat body.

[0030] Preferably, the fixed end of the driving mechanism is located on the inner side of the second seat body, and a notch is provided on the outer wall of the second seat body;

DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0038] like Figure 1-2 As shown, a rivet 100 picking and placing mechanism includes a fixed seat and a driving mechanism; the fixed seat is provided with an opening 1, and a mounting portion is provided inside the fixed seat, and a locking slider 2 is provided on the mounting portion for radial movement thereof, and the locking slider 2 is provided with an inclined hole 3; the active end of the driving mechanism is slidably connected with the locking slider 2 through the inclined hole 3, and the active end of the driving mechanism moves axially relative to the fixed seat to drive the locking slider 2 to move radially relative to the fixed seat.

[0039] In this embodiment, the fixed seat includes a seat body 1 4 and a seat body 2 5, and the seat body 1 4 and the seat body 2 5 are detachably connected, and a component accommodating space is formed between the seat body 1 4 and the seat body 2 5. Therefore, in this embodiment, the driving mechanism, the locking slider 2 and other components are all located in the accommodating space. Since the seat body 1 4 and the seat body 2 5 are detachable, the driving mechanism, the locking slider 2 and other components can be conveniently taken out, thereby meeting the needs of replacement, maintenance and the like. In this embodiment, the driving mechanism is specifically a cylinder component, which meets the movement requirements of the locking slider 2 by inputting and releasing high-pressure gas. During specific use, the active end of the driving mechanism and the inclined hole 3 are slidably matched, and by pulling or pushing, the active end of the driving mechanism drives the locking slider 2 to move radially along the fixed seat during the axial movement of the fixed seat. In this embodiment, the fixed end of the driving mechanism is located on the inner side of the seat body 2 5, and the outer wall of the seat body 2 5 is provided with a notch 6; the fixed end of the driving mechanism is provided with a trachea joint 7, and the trachea joint 7 extends out of the fixed seat from the notch 6. The air pipe joint 7 can be connected to a hose to prevent the interface from loosening when an external driving device drives the rivet 100 picking and placing mechanism to move.

[0040] It can be known that, in different embodiments, there can be one locking slider 2 or multiple locking sliders 2. When there is only one locking slider 2, a locking piece is provided in the fixed seat. At this time, the locking slider 2 moves relative to the locking piece, so that the rivet 100 is clamped between the locking slider 2 and the locking piece. When there are multiple locking sliders 2, the multiple locking sliders 2 move in conjunction. Specifically, taking two locking sliders 2 as an example, two relative locking sliders 2 are provided in the fixed seat, and the rivet 100 is clamped or released by the relative movement of the two locking sliders 2; the active end of the driving mechanism is configured as a double-linked inclined guide column 8, and the double-linked inclined guide column 8 is slidably matched with the inclined holes 3 provided on the two locking sliders 2 at the same time.

[0041] The double-linked oblique guide column 8 has two guide parts 9, that is, each guide part 9 is matched with an oblique hole 3. When the driving mechanism is activated, its active end pulls or pushes the double-linked oblique guide column 8 to move, so that the guide part 9 slides relative to the oblique hole 3, thereby realizing the relative movement between the two locking sliders 2. Similarly, if the number of locking sliders 2 is greater than two, the relative movement between multiple locking sliders 2 can also be realized through a similar structure.

[0042] In this embodiment, the mounting portion is configured as a positioning plate 10, and the active end of the driving mechanism passes through the positioning plate 10 and is connected to the locking slider 2; a plurality of balls 11 are arranged between the positioning plate 10 and the locking slider 2. The positioning plate 10 provides a mounting position for the locking slider 2, so that the sliding of the locking slider 2 occurs on the positioning plate 10, thereby realizing motion limitation in the axial direction of the fixed seat, and the balls 11 can effectively reduce the friction between the positioning plate 10 and the locking slider 2, thereby making the process of clamping and releasing the rivet 100 smoother.

[0043] In this embodiment, an elastic member 12 is provided between the locking slider 2 and the fixing seat in the radial direction of the fixing seat. Figure 1 As shown, the distance between the two inclined holes 3 gradually decreases from the direction close to the opening 1 to the direction away from the opening 1. Therefore, when the driving mechanism drives the double-linked inclined guide column 8 to move upward, the two locking sliders 2 move away from each other, and the elastic member 12 is compressed and deformed, so that the rivet 100 can be placed between the two locking sliders 2 through the opening 1. When the driving mechanism drives the double-linked inclined guide column 8 to move downward, the two locking sliders 2 move toward each other, and the elastic member 12 recovers, thereby keeping the two locking sliders 2 relatively still during the process of the driving mechanism stopping, thereby well meeting the requirements of clamping the rivet 100. In other words, under the action of high-pressure air, the locking piston drives the double-linked inclined guide column 8 to move, and three forces are generated on the inclined guide column: F, Fa, and Fb; Figure 2 As shown, the force F is perpendicular to the inclined surface of the guide portion, the force Fb realizes the up and down driving, and the horizontal force Fa can realize the horizontal movement of the locking slider 2, thereby clamping or loosening the rivet 100. Furthermore, a mounting groove is provided at the end of the locking slider 2, and one end of the elastic member 12 is provided in the mounting groove. The elastic member 12 is radially positioned by the mounting groove, so that the elastic member 12 can only deform along its axial direction, thereby better meeting the clamping requirements of the rivet 100. Furthermore, the opening 1 is provided with a positioning portion 13 extending toward the inner side of the fixed seat, which is used to limit the radial displacement of the locking slider 2; the locking slider 2 is provided with a step portion 14 that cooperates with the positioning portion 13. Although the double-linked inclined guide column 8 combined with the elastic member 12 can maintain the relative position of the locking slider 2 during the process of clamping the rivet 100, in some special cases, the locking slider 2 may undergo transitional movement, causing the rivet 100 to be damaged. Therefore, the setting of the step portion 14 is adapted to the structure of the rivet 100, that is, the travel of the locking slider 2 is limited. In other words, in the process of using high-pressure gas to drive the locking slider 2, it is possible to prevent the locking slider 2 from exerting excessive force on the rivet 100 and causing damage to the rivet 100.

[0044] In this embodiment, the driving mechanism includes a driving piston 15, and the driving piston 15 is provided with an annular groove 16; the double-linked oblique guide column 8 is provided with a hook 17 that cooperates with the annular groove 16, and the hook 17 is slidably connected with the annular groove 16. In this embodiment, the cooperation between the driving piston 15 and the double-linked oblique guide column 8 is simple, and the assembly of the two can be realized quickly. The driving mechanism is located in the fixed seat, so the fixed end of the driving mechanism is fixedly arranged in the seat body 2 5. On the basis that the movement path of the locking slider 2 is limited by the elastic member 12 and the positioning portion 13, the guide portion of the double-linked oblique guide column 8 cooperates with the oblique hole 3, so that it can ensure that the driving double-linked oblique guide column 8 has a stable movement path. Therefore, the double-linked oblique guide column 8 and the piston cylinder that only slide together can be well affected by the high-pressure gas to realize the locking and releasing function.

[0045] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
