[0038] Embodiment 1:

[0039] See also Figure 1 and Figure 2 The present embodiment provides a rivet conveying device 100, which is applied to a rivet machine head 1 to convey rivets to a riveting position. The rivet machine head 1 here is mainly used for riveting multilayer boards of circuit boards, and of course, it can also be used for riveting other boards. Among them, in the present embodiment, a plurality of rivet holes are drilled on the circuit boards to be riveted. Specifically, the rivet conveying device 100 of the present embodiment includes a fixing plate 20, a rivet feeding tool 30, a rivet feeding and dividing mechanism 40, a conveying track 50, and a rivet discharging mechanism 60. The components of the rivet conveying device 100 are further described below:

[0040] The fixing plate 20 is used for fixing and installing components;

[0041] The rivet feeding tool 30 is arranged on the fixing plate 20 and is used to feed the rivets evenly and smoothly to the designated position;

[0042] The rivet feeding and sorting mechanism 40 is disposed on the fixed plate 20 and is located below the rivet feeding tool 30, and is used to receive the rivets fed from the rivet feeding tool 30 and sort and select the rivets so that the rivets can be directed and orderly into the designated positions;

[0043] The conveying track 50 is arranged on the fixed plate 20, and the feeding end of the conveying track 50 is close to the rivet feeding and distributing mechanism 40, and the discharging end of the conveying track 50 extends from top to bottom to receive the rivets output by the rivet feeding and distributing mechanism 40, and convey the rivets to the position of riveting;

[0044] The rivet discharging mechanism 60 is disposed on the bottom surface of the discharging end of the conveying track, and is used to discharge the rivets on the conveying track 50 in an orderly manner.

[0045] When the rivet needs to be transported to the riveting position, the rivet is first placed in the rivet feeding tool 30, which allows the rivet to be evenly and smoothly fed to the rivet feeding and dividing mechanism 40; then, the rivet is divided and selected by the rivet feeding and dividing mechanism 40, so that the rivet can be orderly and directed into the conveying track; then, it is transported to the position of the riveting rivet by the conveying track 50; after that, the rivet discharging mechanism 60 discharges the rivets on the conveying track in an orderly manner. The whole operation is simple and convenient, effectively ensuring the orderly discharge of multiple rivets, and effectively avoiding the problems of extrusion deformation, blockage or falling.

[0046] See also Figures 3 to 5 The preferred structure of the rivet discharging mechanism 60 in this embodiment is that it includes a discharging mounting member 61, a discharging swing arm member 62, and a discharging power unit 63. The following is a further description of the various parts of the rivet discharging mechanism 60:

[0047] The discharge mounting member 61 is disposed on the bottom surface of the discharge end of the conveying track 50;

[0048] The discharging swing arm component 62 is rotatably disposed on the discharging mounting member 61; the discharging swing arm component 62 includes a first swing arm 621 and a second swing arm 622, the first swing arm 621 is connected to the second swing arm 622, the first swing arm 621 is provided with a first clamping claw 623 for clamping the rivet, and the second swing arm 622 is provided with a second clamping claw 624 for clamping the rivet;

[0049] The discharging power unit 63 is arranged on the discharging mounting member 61 and connected to the discharging swing arm component 62, and is used to drive the discharging swing arm component 62 to rotate and reset.

[0050] Thus, when the rivet discharging mechanism 60 is working, at this moment, the rivet has slid from the feeding end of the conveying track 50 to the discharging end of the conveying track 50. At this moment, the first claw 623 of the first swing arm 621 holds the rivet at the front of the discharging end of the conveying track 50, while the second claw 624 of the second swing arm 622 does not hold any rivet; when the upper rivet head 302 is driven downward by the upper rivet driving source 301 and the transfer mechanism 303, the discharging power unit 63 drives the first swing arm 621 to move downward. 621 rotates in the reverse direction, while the second swing arm 622 rotates in the forward direction, and the second claw 624 pushes the rivet at the front end of the discharge end of the conveying track 50 forward and moves the rivet to the contact point of the first claw 623; at the same time, the second claw 624 clamps the next rivet and fixes it; at this moment, the upper rivet head 302 moves down and inserts into the rivet clamped by the first claw 623, and the upper rivet head 302 moves down to the specified position with the inserted rivet.

[0051] Through the cooperation between the first swing arm 621 and the first clamping claw 623, and the second swing arm 622 and the second clamping claw 624, the rivets that need to be discharged will be accurately moved to the designated position for discharge, while the rivets that do not need to be discharged temporarily will be fixed, which is conducive to the orderly discharge of the rivets and avoids conflicts and errors between the rivets.

[0052] Moreover, the discharging power unit 63 of this embodiment is a telescopic cylinder, which is arranged on the discharging mounting member 61, and the output end of the telescopic cylinder is connected to the discharging swing arm member 62, wherein the telescopic cylinder is a pneumatic actuator that uses air pressure to generate a piston movement of a pneumatic column, and achieves buffering, pushing and pulling, etc. through the expansion and contraction of a telescopic tube. The telescopic cylinder is usually composed of a cylinder barrel, a telescopic tube, a piston, an end cover, a pressure relief hole, etc.

[0053] Preferably, the discharging swing arm member 62 is rotatably arranged on the discharging mounting member 61 through a pivot connection member 64, wherein the discharging swing arm member 62 can be simply and effectively arranged to be rotatable through the arrangement of the pivot connection member 64. Moreover, preferably, the pivot connection member 64 is a pivot screw.

[0054] At the same time, the first swing arm 621 and the second swing arm 622 are connected to each other through a connecting screw, so as to simply and effectively realize the connection between the first swing arm 621 and the second swing arm 622.

[0055] See also Figure 2The rivet feeding tool 30 of this embodiment includes a hopper 31. The upper end of the hopper 31 is provided with an inlet for the rivets to enter the interior thereof, and the lower end of the hopper 31 is provided with an outlet for the rivets to leave the interior thereof. The area of ​​the inlet is larger than the area of ​​the outlet. The setting of the hopper 31 can not only make the rivet feeding smooth, but also adjust the rivets evenly and feed them smoothly to the designated position.

[0056] See also Figure 2 , and combined with Figure 6 and Figure 7 The preferred structure of the rivet feeding and distributing mechanism 40 of this embodiment is that it includes a rotating centrifugal disk 41 and a rotating driving source 42. The following is a further description of the various components of the rivet feeding and distributing mechanism 40:

[0057] The rotating centrifugal disc 41 is rotatably disposed on the fixed plate 20, and a rotating cavity 411 is provided in the rotating centrifugal disc 41 for placing rivets therein, and a material distribution slot 412 is provided on the periphery of the rotating centrifugal disc 41 for distributing rivets, and the material distribution slot 412 is communicated with the rotating cavity 411;

[0058] The rotation driving source 42 is on the fixed plate 20 , and one end of the rotation driving source 42 is connected to the rotating centrifugal disk 41 for driving the rotating centrifugal disk 41 to rotate.

[0059] When the rivet enters the rotating cavity 411 of the rotating centrifugal disk 41 from the rivet feeding tool 30, the rotating driving source 42 will drive the rotating centrifugal disk 41 to rotate. At this time, due to the rotational centrifugal force of the rotating centrifugal disk 41, the rivet will be rotated and pushed into the dividing slot 412 on the periphery of the rotating centrifugal disk 41, thereby realizing the dividing and selecting of the rivet, and at the same time, ensuring the orderly orientation of the rivet, thereby better orienting the rivet in an orderly manner to enter the conveying track 50.

[0060] In order to allow more rivets to be rotated and pushed into the material distribution slots 412 on the periphery of the rotating centrifugal disk 41 to improve production efficiency, preferably, at least two material distribution slots 412 are provided. Preferably, the material distribution slots 412 of this embodiment are provided with eighteen. Of course, the material distribution slots 412 can also be set to twenty, twenty-four, etc. according to actual needs, and these implementations also belong to the protection scope of this embodiment, and the following description also takes the eighteen material distribution slots 412 as the description object. The eighteen material distribution slots 412 are evenly spaced and arranged on the periphery of the rotating centrifugal disk 41 with the central axis of the rotating centrifugal disk 41 as the rotation axis.

[0061] Preferably, the rotary drive source 42 of the present embodiment is a rotary cylinder, and the output end of the rotary cylinder is connected to the rotating centrifugal disk 41. The rotary cylinder is composed of a cylinder body, a seal, a guide element, a transmission mechanism and a rotating component, wherein the rotating component can be a gear, a crankshaft, etc. The working principle of the rotary cylinder is based on the effect of aerodynamics, and the kinetic energy is converted into rotational motion through the coordination of air pressure and mechanical structure. Specifically, when the air source supplies air to the rotary cylinder, the piston in the cylinder will be pushed outward as the air pressure increases, and at the same time, the kinetic energy will be converted into rotational motion through the transmission mechanism, thereby driving the equipment to rotate. When the air source is turned off, the pressure inside the cylinder will naturally decrease, causing the rotating component to return to its original position.

[0062] Optionally, the rotary drive source 42 of the present embodiment is a motor, and the output end of the motor is connected to the rotating centrifugal disc 41. Specifically, the motor of the present embodiment is preferably a servo motor. Among them, the servo motor refers to an engine that controls the operation of mechanical components in a servo system, and is an auxiliary motor indirect speed change device. The servo motor can control the speed, and the position accuracy is very accurate. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator, and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases at a uniform rate with the increase of torque.

[0063] Embodiment 2:

[0064] See also Figure 1 , and combined with Figures 2 to 7 , is another preferred embodiment of the utility model, which has the implementation content of the above embodiment, wherein the specific implementation of the above embodiment can refer to the above description, and the embodiment here will not be repeated in detail; and in the embodiment of the present application, it is different from the above embodiment in that:

[0065] The present embodiment can also provide a rivet head 1, including a mounting frame 200, an upper rivet assembly 300, a lower rivet assembly 400, and the above-mentioned rivet conveying device 100. The following is a further description of the various parts of the rivet head 1:

[0066] The upper rivet assembly 300 is disposed at the upper end of the mounting frame 200, and is used to move from top to bottom to insert a rivet located at a designated position, and press the rivet into the riveting hole at the upper end of the circuit board that needs to be riveted;

[0067] The lower rivet assembly 400 is disposed at the lower end of the mounting frame 200 and is disposed opposite to the upper rivet assembly 300, and is used to move upward from bottom to top to extend into the rivet hole at the lower end of the circuit board to be riveted, and cooperate with the upper rivet assembly 300 to rivet the rivet placed on the rivet hole of the circuit board to be fixed on the circuit board;

[0068] The rivet conveying device 100 is disposed on the mounting frame 200 , and is used to park and set the supplied rivets, and convey the rivets to the riveting position between the upper rivet assembly 300 and the lower rivet assembly 400 .

[0069] When it is necessary to perform riveting operation on the circuit board, the circuit board to be riveted is inserted into the positioning pin of the lower rivet head and placed on the jig plate at the same time, and then the rivet is conveyed to the specified position between the upper rivet assembly 300 and the lower rivet assembly 400 by the rivet conveying device 100; then, the upper rivet assembly 300 is controlled to work so that the upper rivet assembly 300 can operably press the circuit board to be riveted; then, the upper rivet assembly 300 is controlled to move to insert the rivet, and press the rivet into the rivet hole at the upper end of the circuit board to be riveted; then, the lower rivet assembly 400 is controlled to move from bottom to top to punch the rivet hole at the lower end of the circuit board to be riveted, and the lower rivet assembly 400 is riveted to cooperate with the upper rivet assembly 300 to rivet the rivet placed on the rivet hole of the circuit board and fix the circuit board.

[0070] Accordingly, when the circuit board is riveted, the circuit board is pressed by the upper rivet assembly 300, the circuit board and the rivet are fixed, and when the lower rivet assembly 400 moves upward and is riveted together with the upper rivet assembly 300, the lower rivet assembly 400 moves from bottom to top, and the rivet is subjected to the force of the lower rivet assembly 400, which acts on the upper rivet assembly 300 through the rivet. Therefore, the force of the upper rivet assembly 300 and the lower rivet assembly 400 will not act on the circuit board, thereby preventing the circuit board from being easily dented or deformed due to pressure, thereby solving the problem of layer deviation and effectively ensuring a high yield rate of the circuit board.

[0071] See also Figure 2 The upper rivet assembly 300 of this embodiment preferably has a structure that includes an upper rivet driving source 301, an upper rivet head 302, a transfer mechanism 303 and a pressing plate mechanism 304. The following further describes the various parts of the upper rivet assembly 300:

[0072] The upper rivet driving source 301 is disposed at the upper end of the mounting frame 200;

[0073] The upper rivet head 302 is disposed below the upper rivet driving source 301;

[0074] The transfer mechanism 303 is disposed at the upper end of the mounting frame 200, and one end of the transfer mechanism 303 is connected to the upper rivet driving source 301, and the other end of the transfer mechanism 303 is connected to the upper rivet head 302, and is used to move the upper rivet head 302 up and down by the driving of the upper rivet driving source 301;

[0075] The pressing plate mechanism 304 is disposed on the upper rivet head 302 and is used to press the circuit board; preferably, the pressing plate mechanism 304 includes a pressing plate member, which is disposed on the upper rivet head 302, and the pins of the upper rivet head 302 can move through the pressing plate member.

[0076] Accordingly, when the upper rivet assembly 300 is working, the upper rivet driving source 301 will start working, and the power generated by the upper rivet driving source 301 will be transmitted to the transfer mechanism 303. After the transfer mechanism 303 is subjected to force, it will drive the upper rivet head 302 to move up and down, so that the circuit board can be first pressed by the pressing plate mechanism 304, and then the upper rivet head 302 can accurately and effectively insert the rivet at the specified position, and at the same time press the rivet into the riveting hole at the upper end of the circuit board that needs to be riveted. The entire operation is an automated operation, eliminating the inconvenience of manual operation, and is also conducive to reducing the labor intensity of operators.

[0077] Preferably, the upper rivet driving source 301 is a servo motor to ensure that the driving force is sufficient and easy to control, and is also conducive to material collection and installation. In addition, the transfer mechanism 303 is a screw module to ensure that the upper rivet head 302 can move up and down smoothly.

[0078] See also Figure 1 The preferred structure of the lower rivet assembly 400 of this embodiment is that it includes a lower rivet driving source, a lower support 402 and a lower rivet head 403. The following is a further description of the various parts of the lower rivet assembly 400:

[0079] The lower rivet driving source is disposed at the lower end of the mounting frame 200;

[0080] The lower support 402 is located above the lower rivet driving source and is fixed to the lower end of the mounting frame 200;

[0081] The lower rivet head 403 is disposed on the lower rivet driving source and connected to the lower rivet driving source.

[0082] Accordingly, when the lower rivet assembly 400 is working, the lower rivet driving source will start working, which will push the lower rivet head 403 to move so as to extend into the rivet hole at the lower end of the circuit board that needs to be riveted, and cooperate with the upper rivet head 302 to rivet the rivet placed on the rivet hole of the circuit board to be fixed on the circuit board; at the same time, the lower support 402 will also press against the lower end surface of the circuit board as pushed by the lower rivet driving source, so as to reduce the force applied to the circuit board during riveting and avoid deformation problems such as warping and concave of the circuit board.

[0083] In order to make the lower rivet head 403 and the upper rivet head 302 cooperate smoothly by riveting, so as to ensure that the rivets placed on the riveting holes of the circuit board can be riveted and fixed on the circuit board smoothly and quickly, the driving source of the lower rivet is a booster cylinder. Among them, the booster cylinder is also called a gas-liquid booster cylinder. The booster cylinder is improved and designed by combining the advantages of the air cylinder and the oil cylinder. The hydraulic oil is strictly isolated from the compressed air. The piston rod in the cylinder automatically starts after contacting the working piece. The action speed is fast and more stable than the pneumatic transmission. The cylinder body is simple to install and the output is easy to adjust. Under the same conditions, it can achieve the high output of the hydraulic press, low energy consumption, soft landing without damaging the mold, easy installation and the special booster cylinder can be installed at any angle of 360 degrees. It occupies a small space, has few failures and no temperature rise problems, has a long life, and has low noise, etc. Core characteristics.

[0084] The above description is only a preferred embodiment of the present invention, and its structure is not limited to the shapes listed above.
