Description

Technical Field

[0001] The invention relates to the technical field of chip mounters, in particular to a multifunctional chip mounter for chip tinning provided with a feeding structure. Background Art

[0002] In the early stages of the development of the electronics manufacturing industry, the placement machine was mainly responsible for accurately placing surface mount components on the PCB pads, while the tinning machine was specifically used to accurately apply solder paste to the PCB. The two devices were independent of each other.

[0003] With the continuous advancement of electronic technology, electronic products are becoming more and more miniaturized, integrated, and intelligent, and the requirements for electronic manufacturing equipment are becoming higher and higher. As a result, multifunctional SMT machines for SMT and tinning have emerged, which integrate the functions of SMT and tinning, thereby improving work efficiency.

[0004] The existing multifunctional chip placement machine for chip spot tinning still has the following technical problems when in use, such as:

[0005] 1. The existing multifunctional SMT machine for SMT tinning can only feed automatically when in use, but does not have a loading structure, which requires workers to manually load materials, thereby increasing the labor intensity of the workers and is not conducive to improving work efficiency;

[0006] 2. The existing multifunctional SMT machine for SMT tinning is not convenient for reasonable use of space when in use, which leads to waste of space under the SMT machine;

[0007] Therefore, a multifunctional chip placement machine with a feeding structure for chip tinning is needed to solve the above problems. Summary of the invention

[0008] The purpose of the present invention is to provide a multifunctional chip placement machine with a feeding structure for patch tinning, so as to solve the problem mentioned in the above background technology that the existing multifunctional chip placement machine for patch tinning is not provided with a feeding structure and is not convenient for reasonable use of the space below the chip placement machine.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] A multifunctional SMT machine for SMT tinning provided with a feeding structure comprises a machine body, a spring, a clamping assembly, a synchronous drive assembly and a material conveying assembly, wherein a monomer conveying mechanism is provided on the machine body, and an arc-shaped through groove is provided at one end of the machine body, a through rod is slidably penetrated in each of the arc-shaped through grooves, and the outer end of the through rod is connected to the upper end of the spring, and the lower end of the spring is connected to a protrusion on the outer side of the machine body, a clamping assembly is installed at the inner end of the through rod, a pressure block is connected at the upper end of the arc-shaped through groove, and the pressure block and the clamping assembly are arranged correspondingly, the outer end of the through rod is toggled by the synchronous drive assembly, and the synchronous drive assembly is installed on the machine body, a material conveying assembly is also provided on the inner side of the machine body, and the middle part of the material conveying assembly is connected to the synchronous drive assembly.

[0011] Furthermore, the middle portion of the through rod is arc-shaped, and the arc-shaped middle portion matches the arc-shaped through groove, and the two are slidably connected.

[0012] By adopting the above technical solution, the rotation of the through rod can be limited by the arc-shaped middle part to prevent the self-rotation of the through rod, thereby ensuring the stability of feeding.

[0013] Furthermore, both ends of the spring one are hook-shaped, and the two ends of the spring one are respectively sleeved on the outer end of the penetrating rod and the protrusion on the outer side of the body.

[0014] By adopting the above technical solution, the spring one can rotate through the two ends of the hook-shaped spring one, and then can be stretched as the penetrating rod moves in the arc-shaped through groove.

[0015] Furthermore, the clamping assembly includes a mounting frame, a lifting plate, a self-resetting twisted shaft tube, a connecting portion, a clamping portion, a twisted rod, a weight ball, a connecting shaft, a limiting triangle block, a T-shaped block and a seesaw. The mounting frame is connected to the inner end of the penetration rod, and the upper and lower sides of the mounting frame are both provided with self-resetting twisted shaft tubes through the bearings. The two self-resetting twisted shaft tubes on the same mounting frame are connected by coaxial bearings, and the two coaxial self-resetting twisted shaft tubes are penetrated by the twisted rod thread. The two self-resetting twisted shaft tubes are connected by coaxial bearings. The outer key of the shaft tube is connected to a connecting part in the opposite direction, and the outer end of each connecting part is connected to a clamping part through a connecting shaft. The lower end of the twisted rod is connected to a heavy ball through a steel wire rope, and the upper end of the twisted rod is coaxially connected to a T-shaped block. The lower middle part of the T-shaped block is snap-connected to one end of the seesaw, and the seesaw shaft is connected to the upper surface of the mounting frame. A limiting triangular block is also provided on the connecting part, and the limiting triangular block is arranged close to the corresponding clamping part. A lifting plate is also provided on the side of the mounting frame.

[0016] By adopting the above technical solution, when the through rod moves in the arc-shaped through groove, the gravity of the heavy ball pulls the twisted rod, so that the two self-resetting twisted shaft tubes drive the two connecting parts to rotate in opposite directions, so that the two clamping parts can be gradually approached, and then the PCB board can be gradually clamped. In addition, through the limiting triangle block, the PCB board can be moved between the two clamping parts to ensure the continuity of the operation. When the through rod moves to the top of the arc-shaped through groove, the seesaw contacts the pressing block, so that the seesaw is squeezed and the twisted rod is pulled, so that the two clamping parts gradually release the PCB board.

[0017] Furthermore, the twisted rod is provided with two sections of threads with opposite rotation directions, and the length of each section of the threads on the twisted rod is not greater than 1 / 2 of the length of the self-resetting twist shaft tube.

[0018] By adopting the above technical solution, the twisted rod can drive the two self-resetting twisted shaft tubes connected thereto to rotate in opposite directions when moving, and also avoids the thread length being too long, which affects the rotation of the two self-resetting twisted shaft tubes.

[0019] Furthermore, the lower middle portion of the T-shaped block is a prismatic structure, and one end of the seesaw engaged with the lower middle portion of the T-shaped block is also provided with a prismatic groove that matches the T-shaped block, and the other end of the seesaw is correspondingly arranged with the pressing block.

[0020] By adopting the above technical solution, the rotation of the twisted rod can be limited by the prismatic structure, ensuring that it can only move but not rotate.

[0021] Furthermore, the synchronous drive assembly includes a shift rod, a shaft rod, a belt transmission mechanism, a linkage rod and a servo motor. The shaft rods are provided with bearings on both the front and rear sides of the body, and the outer ends of the two shaft rods are connected to the ends of the linkage rods through the belt transmission mechanism. The linkage rod bearings are arranged through the body. The shift rod is arranged on the outside of each shaft rod, and one of the two shaft rods is coaxially connected to the shaft end of the servo motor after passing through the body to which it is connected, and the servo motor is installed on the inner side of the body.

[0022] By adopting the above technical solution, the servo motor is operated to drive one of the two shafts to rotate, and then the two shafts are rotated synchronously through the belt transmission mechanism and the linkage rod. Through the synchronous rotation of the two shafts, the two levers can be rotated synchronously.

[0023] Furthermore, the axis of the servo motor shaft end is lower than the height of the center of the arc groove, the length of the shift rod is equal to the distance from the axis of the shaft rod to the upper end of the arc groove, and the distance from the axis of the shaft rod to the upper end of the arc groove is greater than the distance from the lower end of the arc groove.

[0024] By adopting the above technical solution, the shaft rod drives the lever to rotate when it rotates, so that the lever can first drive the through rod to rotate. When the through rod moves to the upper end of the arc-shaped through groove, at this time, due to the insufficient length of the lever, it will gradually separate from the through rod. Thereafter, the through rod is reset under the action of spring 1, and then, after the lever rotates one circle, it continues to drive the through rod to move on the arc-shaped through groove, and this is repeated.

[0025] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm is hinged on the base plate, is fixed with the support of base plate, and the swing arm is hinged on the base plate, is fixed with the support of base plate, and the swing arm is hinged on the base plate, is fixed with the support of base plate.

[0026] By adopting the above technical solution, the material plate can be conveyed by the conveyor belt, and the material plate is equipped with a PCB board. When the conveyor belt is running, the PCB board is driven to move, and the frontmost PCB board is moved between the two clamping parts. In the process of the two clamping parts clamping and driving the PCB board to move, the cam rotates and squeezes the paddle, so that the support plate can move backward as a whole, thereby preventing the clamped PCB board from scratching the rear PCB board when it rotates.

[0027] Furthermore, the material plate is in a flat N-shape and is used to be clamped on a conveyor belt for transportation.

[0028] By adopting the above technical solution, the material plate can be easily placed on the conveyor belt for transportation.

[0029] Compared with the prior art, the invention has the following beneficial effects: the multifunctional chip placement machine with a feeding structure is provided with a feeding structure, so that manual feeding is not required, the labor intensity of the staff is reduced, and the work efficiency is improved. In addition, the space below the chip placement machine can be reasonably utilized to avoid space waste:

[0030] 1. The synchronous driving assembly can drive the penetration rod to move on the arc-shaped slot, so that the clamping assembly can gradually clamp the PCB board. When the penetration rod moves to the uppermost end of the arc-shaped slot, the clamping assembly will release the PCB board through the extrusion of the pressure block. At this time, the PCB board will be further transported to the designated position by the monomer conveying mechanism for processing. When the penetration rod moves to the uppermost end of the arc-shaped slot, the lever will be separated from the penetration rod due to insufficient length, so that the penetration rod is reset under the action of spring 1, so as to facilitate reciprocating feeding;

[0031] 2. The material conveying assembly can cooperate with the synchronous driving assembly and the clamping assembly, so that the PCB board on the material plate can be gradually transferred to the monomer conveying mechanism, and then the material can be continuously loaded. In addition, the material conveying assembly is arranged under the machine body, which can facilitate the rational use of space. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Embodiment 1: In order to solve the problem that the conventional multifunctional SMT machine for SMT spot tinning is not provided with a feeding mechanism and needs manual feeding, which is inefficient, the following technical solution is provided, specifically, a multifunctional SMT machine for SMT spot tinning with a feeding structure, comprising a machine body 1, a spring 12, a clamping assembly, a synchronous drive assembly and a material conveying assembly, a monomer conveying mechanism 2 is provided on the machine body 1, and an arc-shaped through groove 3 is provided at one end of the machine body 1, and a through rod 1 is slidably penetrated and connected in each arc-shaped through groove 3 1, and the outer end of the through rod 11 is connected to the upper end of the spring 12, and the lower end of the spring 12 is connected to the outer protrusion of the body 1, the inner end of the through rod 11 is installed with a clamping assembly, the upper end of the arc-shaped through groove 3 is connected with a pressure block 23, and the pressure block 23 is arranged corresponding to the clamping assembly, the outer end of the through rod 11 is moved by the synchronous drive assembly, and the synchronous drive assembly is installed on the body 1, and a material conveying assembly is also arranged on the inner side of the body 1, and the middle part of the material conveying assembly is connected to the synchronous drive assembly.

[0046] The middle part of the through rod 11 is arc-shaped, and the middle part of the arc is consistent with the arc-shaped through groove 3, and the two are slidably connected. Both ends of the spring 12 are hook-shaped, and the two ends of the spring 12 are respectively sleeved on the outer end of the through rod 11 and the protrusion on the outer side of the body 1. The clamping assembly includes a mounting frame 24, a lifting plate 25, a self-resetting twisted shaft tube 26, a connecting part 27, a clamping part 28, a twisted rod 29, a heavy ball 30, a connecting shaft 31, a limiting triangle block 32, a T-shaped block 33 and a seesaw 34. The mounting frame 24 is connected to the inner end of the through rod 11, and the upper and lower sides of the mounting frame 24 are both bearing-pierced with a self-resetting twisted shaft tube 26. The same mounting frame 24 The two self-resetting twisted shaft tubes 26 on the upper part are connected by coaxial bearings, and the two coaxial self-resetting twisted shaft tubes 26 are threaded through the twisted rod 29, the outer side keys of the two self-resetting twisted shaft tubes 26 are connected with connecting parts 27 in opposite directions, and the outer ends of each connecting part 27 are connected with a clamping part 28 through a connecting shaft 31, the lower end of the twisted rod 29 is connected with a heavy ball 30 through a wire rope, and the upper end of the twisted rod 29 is coaxially connected with a T-shaped block 33, the middle and lower parts of the T-shaped block 33 are snap-connected to one end of the seesaw 34, and the seesaw 34 is axially connected to the upper surface of the mounting frame 24, and a limited position triangle block 32 is also provided on the connecting part 27, and the limited position triangle block 32 The mounting frame 24 is provided with a lifting plate 25 on the side thereof, the twisted rod 29 is provided with two sections of threads with opposite rotation directions, and the length of each section of the threads on the twisted rod 29 is not greater than 1 / 2 of the length of the self-resetting twisted shaft tube 26, the middle and lower part of the T-shaped block 33 is a prismatic structure, and one end of the seesaw 34 engaged with the middle and lower part of the T-shaped block 33 is also provided with a prismatic groove that matches the T-shaped block 33, and the other end of the seesaw 34 is provided corresponding to the pressing block 23, the synchronous drive assembly includes a lever 13, a shaft 14, a belt transmission mechanism 15, a linkage rod 16 and a servo motor 22, and the front and rear sides of the body 1 are both provided with bearings There are shafts 14, and the outer ends of the two shafts 14 are connected to the ends of the linkage rods 16 through the belt transmission mechanism 15. The bearing of the linkage rod 16 is set through the body 1. The lever 13 is set on the outside of each shaft 14, and one of the two shafts 14 is coaxially connected to the shaft end of the servo motor 22 after penetrating the body 1 to which it is connected, and the servo motor 22 is installed on the inner side of the body 1. The axis of the shaft end of the servo motor 22 is lower than the height of the center of the arc groove 3. The length of the lever 13 is equal to the distance from the axis of the shaft 14 to the upper end of the arc groove 3, and the distance from the axis of the shaft 14 to the upper end of the arc groove 3 is greater than the distance from the lower end of the arc groove 3.

[0047] When in use, the servo motor 22 is started to rotate the shaft rod 14 on one side, and then the shaft rod 14 on the other side is rotated synchronously through the belt transmission mechanism 15 and the linkage rod 16, so that the two shifting rods 13 can rotate synchronously through the two synchronously rotating shaft rods 14, and the two through rods 11 can be synchronously shifted, ensuring that the two through rods 11 can drive the two installation frames 24 to move synchronously along the arc-shaped through groove 3.

[0048] In the above process, after the two installation frames 24 move synchronously along the arc-shaped through groove 3 for a distance, the heavy ball 30 will be suspended in the air. Since it is no longer supported on the material plate 7, its suspension will drag the twist rod 29, causing the twist rod 29 to move downward about the self-resetting twist shaft tube 26, thereby driving the two self-resetting twist shaft tubes 26 to rotate in opposite directions, so as to achieve the purpose of driving the two clamping parts 28 to rotate in opposite directions. Through the two clamping parts 28 rotating in opposite directions, the two clamping parts 28 can gradually and stably clamp the PCB board. After that, the two installation frames 24 continue to move synchronously along the arc-shaped through groove 3, which can drive the PCB board to move synchronously along the arc-shaped through groove 3, thereby realizing the transportation of the PCB board.

[0049] When the two mounting frames 24 synchronously move to the highest position along the arc-shaped through groove 3, the seesaw 34 will be gradually squeezed by the pressing block 23, thereby causing the seesaw 34 to rotate, thereby achieving the purpose of driving the T-shaped block 33 to move upward. During the upward movement, the T-shaped block 33 will drive the twist rod 29 to move synchronously, which can resist the gravity of the heavy ball 30, thereby resetting the two self-resetting twist shaft tubes 26, thereby achieving the purpose of gradually loosening the PCB board by the two clamping parts 28. After that, the PCB board will be transported to the processing position by the monomer conveying mechanism 2 for processing due to its contact with the monomer conveying mechanism 2.

[0050] By repeatedly carrying out the above process, the PCB board can be continuously transported to the processing position for processing, thereby achieving the purpose of automatic loading. Since it does not require manual loading by staff, it not only reduces the labor intensity of staff, but also improves work efficiency.

[0051] Embodiment 2: To solve the problem that the multifunctional SMT machine for SMT spot tinning cannot reasonably utilize the space below the SMT machine and cannot facilitate continuous loading, specifically, the material conveying assembly includes a slide rail 4, a support plate 5, a conveyor belt 6, a material plate 7, a roller 8, a slide groove 9, a slider 10, a limit rod 17, a spring 18, a support rod 19, a cam 20 and a paddle 21, the slide rail 4 is arranged at the inner bottom of the machine body 1, and the slide rail 4 is slidably connected with the support plate 5, the two support plates 5 are connected by the support rod 19, and the two support plates 5 are installed with a conveyor belt 6, the conveyor belt 6 supports the material plate 7, and the outer side of the support plate 5 is connected by the slider 10 It is connected to the slide groove 9, and the slide groove 9 is set through the lower end of the machine body 1. A limit rod 17 is movably passed through the slider 10, and the two ends of the limit rod 17 are respectively fixedly connected to the two ends of the corresponding slide groove 9. A spring 2 18 is arranged on the outer side of the limit rod 17, and the two ends of the spring 2 18 are respectively connected to one end of the corresponding slider 10 and one end of the corresponding slide groove 9. A roller 8 is installed between one end of the two support plates 5, and a paddle 21 is arranged in the middle of the upper surface of each support plate 5. A cam 20 is corresponding to the top of each paddle 21, and the cam 20 is installed on the linkage rod 16. The material plate 7 is a flat n-shaped material plate, which is used to be clamped on the conveyor belt 6 for transportation.

[0052] When in use, the conveyor belt 6 is arranged below the body 1, so that the space below the body 1 can be reasonably utilized. In addition, in the process of conveying the material plate 7 by the conveyor belt 6, the limiting rotation structure formed by the limiting triangle block 32 and the connecting shaft 31 can make the PCB board at the front end of the material plate 7 gradually inserted into the two clamping parts 28, so that it is convenient to cooperate with the clamping assembly to continuously clamp the PCB board, thereby achieving the purpose of automatic loading.

[0053] At the same time, during the operation of the clamping assembly, the linkage rod 16 rotates to drive the cam 20 to rotate. When the cam 20 rotates, it toggles the paddle 21 to move the support plate 5, thereby preventing the PCB board whose front end is clamped and conveyed by the clamping assembly from contacting the rear PCB board at its lower end when it moves along the arc-shaped through groove 3, thereby avoiding damage to the rear PCB board. The reset structure formed by the slide groove 9, the slider 10, the limit rod 17, the spring 18 and the support rod 19 can make the cam 20 intermittently toggle the paddle 21 during the rotation process, and make the support plate 5 reciprocate left and right. The reciprocating movement of the support plate 5 can not only avoid damage to the rear PCB board, but also increase the density of PCB boards placed on the material plate 7, thereby reducing the length of the conveyor belt 6 extending outside the body 1, which helps to save space and reduces the frequency of staff placing the material plate 7 on the conveyor belt 6, thereby reducing the labor intensity of the staff.

[0054] It should be noted that the single-body conveying mechanism 2 is a feeding structure on an existing placement machine, and its function is to convey the PCB board to a suitable position for processing.

[0055] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
