Description

Technical Field

[0001] This utility model relates to the field of chip resistor granulation screening technology, specifically a chip resistor granulation screening machine. Background Technology

[0002] Surface mount resistors are a type of electronic component that is mounted on the surface. Their core function is to limit current and distribute voltage in a circuit. Due to their small size and ability to be automatically soldered, they are widely used in electronic devices such as mobile phones, computers, and home appliances.

[0003] Currently, the production process of surface mount resistors requires granulation, which involves cutting or separating the continuously formed surface mount resistor "strip" into individual resistor particles. After granulation, defective products need to be removed by a screening machine to achieve efficient production and quality control. However, most current screening methods use filter plates. During screening, qualified products remain on the filter plate, and when a certain quantity accumulates, screening needs to be stopped, and qualified products need to be manually removed, affecting screening efficiency. To address these issues, the inventor proposes a surface mount resistor granulation screening machine to solve the above problems. Summary of the Invention

[0004] To address the issue of manually removing qualified products, the purpose of this invention is to provide a chip resistor granulation screening machine.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a chip resistor pelletizing and screening machine, comprising a screening box, with movable plates vertically slidably installed on both sides of the middle of the screening box, and a filter frame horizontally slidably installed between the two movable plates. Two No. 2 electric cylinders are fixedly installed on the side of the screening box, and one end of the output shaft of each of the two No. 2 electric cylinders is installed inside the filter frame. Two push plates are slidably installed on one side of the screening box, and a moving strip is slidably installed on the side of each of the two push plates. Two No. 3 springs are fixedly installed on both sides of each of the two push plates, and the top of each No. 3 spring is fixedly connected to the moving strip. Four No. 1 electric cylinders are fixedly installed on the side of the screening box, and one end of the output shaft of each No. 1 electric cylinder is fixedly connected to the moving strip. Two rotating plates are rotatably installed on the side of the screening box away from the push plates, and the push plates and rotating plates are in contact. A No. 1 spring is fixedly installed on both sides of the top of each of the two rotating plates, and the end of the No. 1 spring away from the rotating plate is fixedly connected to the inside of the screening box. The lower surface of the push plate and the upper surface of the filter frame are in contact to push out the chip resistor pellets.

[0006] Preferably, two No. 2 springs are fixedly installed on the lower surfaces of the two movable plates on opposite sides, and the bottom ends of the No. 2 springs are fixedly connected to the inside of the screen box.

[0007] Preferably, drive rods are rotatably installed on both sides of the screening box, and three cams are fixedly installed in the middle of the two drive rods, with the outer surface of the cams in contact with the moving plate.

[0008] Preferably, a crossbar is rotatably installed on the side of the screening box away from the No. 2 electric cylinder. A second bevel gear is fixedly installed at both ends of the crossbar. A first bevel gear is fixedly installed at the end of each of the two drive rods near the crossbar, and the first bevel gear and the second bevel gear mesh with each other. A motor is fixedly installed on the side of the screening box near the No. 1 electric cylinder, and one end of the motor output shaft is fixedly connected to the crossbar.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, a pusher plate is set to push the qualified chip resistor granules to move, so that the chip resistor granules are detached from the filter frame, thereby realizing the unloading of the chip resistor granules. Secondly, a No. 3 spring is set to drive the pusher plate to move, so that the lower surface of the pusher plate and the upper surface of the filter frame are in continuous contact, thus preventing the pusher plate from detaching from the upper surface of the filter frame and affecting the unloading.

Then, the filter frame is moved by a second electric cylinder, which avoids the need to stop the machine to unload the qualified raw materials and improves the screening efficiency.

[0018] 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.

[0019] Example: Figure 1-5 As shown, this utility model provides a chip resistor granulation screening machine, including a screening box 1. Movable plates 2 are vertically slidably installed on both sides of the middle of the screening box 1 to install a filter frame 21 and drive the filter frame 21 to move up and down reciprocally. A filter frame 21 is horizontally slidably installed between the two movable plates 2. Two push plates 3 are slidably installed on one side of the screening box 1 to push qualified raw materials accumulated on the filter frame 21 out of the filter frame 21. The lower surface of the push plate 3 and the upper surface of the filter frame 21 are in active contact to fold and push out the chip resistor granules.

[0020] Two No. 2 electric cylinders 14 are fixedly installed on the side of the screening box 1, and one end of the output shaft of each No. 2 electric cylinder 14 is installed inside the filter frame 21 to drive the filter frame 21 to move. When in use, the No. 2 electric cylinder 14 is turned on to drive the filter frame 21 to move.

[0021] By adopting the above technical solution, the second electric cylinder 14 can drive the filter frame 21 to move.

[0022] Both push plates 3 have sliding strips 31 slidably mounted on their sides. Both sides of the push plates 3 have two No. 3 springs 32 fixedly mounted inside. The top of the No. 3 springs 32 is fixedly connected to the sliding strips 31 to drive the push plates 3 to move. When in use, when the No. 3 springs 32 release the deformation force, they push the push plates 3 to move downward, so that the lower surface of the push plates 3 and the upper surface of the filter frame 21 are in continuous contact.

[0023] By adopting the above technical solution, the No. 3 spring 32 can drive the push plate 3 to move.

[0024] Four No. 1 electric cylinders 11 are fixedly installed on the side of the screening box 1, and one end of the output shaft of the No. 1 electric cylinder 11 is fixedly connected to the moving bar 31 to drive the push plate 3 to move. When in use, the No. 1 electric cylinder 11 is turned on to drive the moving bar 31 to move, and the movement of the moving bar 31 drives the push plate 3 to move.

[0025] By adopting the above technical solution, the No. 1 electric cylinder 11 can drive the push plate 3 to move.

[0026] Two rotating plates 19 are rotatably installed on the side of the screening box 1 away from the push plate 3, and the push plate 3 and the rotating plates 19 are in contact. A first spring 191 is fixedly installed on both sides of the top of the two rotating plates 19, and the end of the first spring 191 away from the rotating plate 19 is fixedly connected to the inside of the screening box 1 to drive the rotating plates 19 to rotate. When the deformation force of the first spring 191 is released during use, the rotating plates 19 are driven to rotate through the first spring 191, so that the rotating plates 19 are reset.

[0027] By adopting the above technical solution, the No. 1 spring 191 can drive the rotating plate 19 to rotate.

[0028] Two second springs 22 are fixedly installed on the lower surfaces of the two movable plates 2 on opposite sides. The bottom ends of the second springs 22 are fixedly connected to the inside of the screen box 1 to drive the movable plates 2 to move. When the second springs 22 release the deformation force, the movable plates 2 are pushed upward by the second springs 22.

[0029] By adopting the above technical solution, the second spring 22 can drive the moving plate 2 to move.

[0030] Drive rods 15 are rotatably installed on both sides of the screening box 1. Three cams 16 are fixedly installed in the middle of the two drive rods 15, and the outer surface of the cams 16 is in contact with the moving plate 2 to drive the moving plate 2 to move downward. In use, the movement of the drive rods 15 drives the cams 16 to rotate, so that the protrusions of the cams 16 contact the moving plate 2, and at this time pushes the moving plate 2 to move downward.

[0031] By adopting the above technical solution, the drive rod 15 can drive the cam 16 to rotate.

[0032] A crossbar 12 is rotatably mounted on the side of the screening box 1 away from the second electric cylinder 14. A second bevel gear 18 is fixedly mounted at both ends of the crossbar 12. A first bevel gear 17 is fixedly mounted at the end of each of the two drive rods 15 near the crossbar 12, and the first bevel gear 17 meshes with the second bevel gear 18. A motor 13 is fixedly mounted on the side of the screening box 1 near the first electric cylinder 11, and one end of the output shaft of the motor 13 is fixedly connected to the crossbar 12 to drive the drive rods 15 to rotate. In use, the motor 13 is turned on to drive the crossbar 12 to rotate. The rotation of the crossbar 12 drives the second bevel gear 18 to rotate, which in turn drives the first bevel gear 17 to rotate, and the rotation of the first bevel gear 17 drives the drive rods 15 to rotate.

[0033] By adopting the above technical solution, the crossbar 12 can drive the drive rod 15 to rotate.

[0034] Working principle: First, the chip resistor pellets are put into the inside of the screening box 1 through the feed port on the upper surface of the screening box 1. At this time, the chip resistor pellets fall onto the filter frame 21. Next, the motor 13 is turned on to drive the crossbar 12 to rotate. The rotation of the crossbar 12 drives the second bevel gear 18 to rotate, which in turn drives the first bevel gear 17 to rotate. The rotation of the first bevel gear 17 drives the drive rod 15 to rotate, and the movement of the drive rod 15 drives the cam 16 to rotate, so that the cam 16's protrusion contacts the moving plate 2. At this time, the moving plate 2 is pushed to move downward, and the second spring 22 deforms. When the cam 16's protrusion disengages from the moving plate 2, the second spring 22 releases the deformation force, pushing the moving plate 2 to move upward, causing the moving plate 2 to move up and down repeatedly. The movement of the moving plate 2 drives the filter frame 21 to move up and down repeatedly, screening the chip resistor particles on the filter frame 21. Then, when a certain number of qualified chip resistors have accumulated, the second electric cylinder 14 is turned on to move the filter frame 21, so that the side of the filter frame 21 contacts the inner wall of the screening box 1, and screening is carried out for a period of time. Finally, the first electric cylinder 11 is turned on to move the moving bar 31. The movement of the moving bar 31 drives the push plate 3 to move, so that the lower surface of the push plate 3 contacts the upper surface of the filter frame 21. At this time, the movement of the push plate 3 pushes the qualified chip resistor pellets piled on the upper surface of the filter frame 21 to move and push them away from the filter frame 21, thereby realizing the unloading of the chip resistor pellets.
