Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts processing technology, specifically a screening and counting device for motorcycle screw parts. Background Technology

[0002] Motorcycle screw screening and counting equipment typically refers to mechanical equipment used for automatically screening and counting various screws used on motorcycles. This type of equipment combines multiple technologies such as vibration screening, optical detection, and automatic counting to efficiently and accurately complete the screening and counting of screws.

[0003] Existing motorcycle screw screening and counting equipment uses a high-resolution CCD camera to photograph the screws and count and classify qualified screws. However, after prolonged use, the CCD camera's lens is easily obscured by dust or impurities, causing the overall image to become blurry and distorted, which in turn affects the accuracy of the counting. Generally, the equipment needs to be stopped and the CCD camera's lens needs to be cleaned manually, which increases the workload of the staff and is inconvenient to use.

[0004] Therefore, we proposed that a motorcycle screw screening and counting device can effectively solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a screening and data acquisition device for motorcycle screw parts, in order to solve the problem mentioned in the background art that after a long period of use, the mirror of the CCD camera is easily blocked by dust or impurities, resulting in a certain degree of blurring and distortion of the overall image, which in turn affects the accuracy of data acquisition. Generally, it is necessary for the staff to stop the equipment and manually clean the mirror of the CCD camera, which increases the workload of the staff and is inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motorcycle screw screening and counting device, comprising a frame and a vibrating plate, wherein a motor is installed at the bottom inside the frame, and an indexing plate is provided on the inner wall of the frame above the motor;

[0007] The bottom of the indexing plate is fixedly connected to the output end of the motor via a shaft. A guide rail is inclinedly arranged between the vibratory plate and the frame. An industrial camera is installed on the left side of the inner wall of the frame.

[0008] It also includes: a fixing plate is fixedly connected to the right side of the top of the inner wall of the frame, and a nozzle is installed below the right side of the fixing plate; a collection box is bolted to the lower right side of the frame; a sleeve is sleeved on the outer side of the indexing disc shaft end, and a ratchet assembly is installed between the inner wall of the sleeve and the outer side of the indexing disc shaft end.

[0009] A transmission rod is connected to the left bearing at the bottom of the inner wall of the frame, and a first pulley assembly is installed between the outer side of the lower end of the transmission rod and the outer side of the sleeve. A reciprocating lead screw and a limiting rod are respectively connected to the left side of the inner wall of the frame below the industrial camera.

[0010] A guide plate is sleeved on the outer side of the reciprocating lead screw and the limiting rod, and a cleaning brush is provided on the top of the guide plate.

[0011] Preferably, the indexing plate is rotatably connected to the frame, and the sleeve is connected to the frame by a bearing.

[0012] Preferably, a support block is fixed on the right side of the inner wall of the frame, and the top of the support block is symmetrically provided with receiving grooves. The inner walls of the two receiving grooves are slidably connected with movable plates. A return spring is installed between the bottom of the movable plate and the inner wall of the receiving groove. The interior of the fixed plate is hollow, and the top of the fixed plate is connected to an external air supply device through a hose. The receiving groove and the fixed plate are connected by a connecting pipe.

[0013] Preferably, the top end of the transmission rod is connected to the outer side of the left end of the reciprocating lead screw via a bevel gear set, and the reciprocating lead screw bearing is connected to the inner wall of the frame.

[0014] Preferably, the limiting rod is fixed to the inner wall of the frame, the front end of the guide plate is threadedly connected to the reciprocating screw, and the rear end of the guide plate is slidably connected to the limiting rod.

[0015] Preferably, each of the three cleaning brushes has a rotating rod bolted to its bottom, and the bottom of the rotating rod penetrates the interior of the guide plate. The outer sides of the lower ends of the three rotating rods are connected to each other via a second pulley assembly. A rack is fixedly connected to the inner wall of the frame between the reciprocating lead screw and the limiting rod. A driven gear is fixed to the outer side of the rear rotating rod.

[0016] Preferably, one end of the rack passes through the interior of the guide plate, and the rack and the driven gear are meshed together. The cleaning brush is rotatably connected to the guide plate via a rotating rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This motorcycle screw screening and counting device uses an industrial camera and a nozzle to screen and count motorcycle screws. Then, a motor drives the indexing plate to rotate in the opposite direction, and a ratchet assembly drives the sleeve to rotate, causing the guide plate to move back and forth on the reciprocating screw. This, in turn, drives the cleaning brush to clean the dust and impurities on the industrial camera lens, preventing dust or impurities on the industrial camera lens from affecting the accuracy of the counting. The specific details are as follows:

[0018] (1) The indexing plate is rotated by the motor, so that the screws move one by one to the bottom of the industrial camera. The industrial camera performs a comprehensive inspection of the screws and counts them. When a defective screw is detected, it is sprayed into the collection box through the nozzle to screen out the defective products, thereby achieving fast and accurate screening and counting of the screws.

[0019] (2) After counting is completed, the indexing plate is rotated in the opposite direction by the motor, and the sleeve is rotated by the ratchet assembly. The sleeve is rotated synchronously by the transmission rod driven by the first belt pulley assembly. At the same time, the transmission rod is rotated by the bevel gear set to drive the reciprocating screw to rotate, so that the guide plate moves back and forth on the reciprocating screw and drives the cleaning brush to clean the dust and impurities on the industrial camera lens back and forth, so as to avoid the industrial camera lens having dust or impurities that affect the accuracy of data acquisition.

[0020] (3) When the guide plate moves back and forth, the rack and pinion can make the driven gear rotate in both directions and drive the rotating rod to rotate, which in turn makes the cleaning brush rotate and clean the mirror of the industrial camera, thereby improving the cleaning effect.

[0021] (4) When the nozzle blows out high-pressure gas, some of the gas will enter the receiving groove through the connecting pipe and push the movable plate to move upward, thereby blocking the screws on the indexing plate, thus preventing the nozzle from blowing unqualified screws into the collection box while also blowing qualified screws into the collection box.

[0030] 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.

[0031] Please see Figures 1-7 This utility model provides the following technical solution: a screening and counting device for motorcycle screw parts;

[0032] Example 1: To address the issue that in existing CCD cameras, after prolonged use, the lens is easily obscured by dust or impurities, leading to overall image blurring and distortion, thus affecting data acquisition accuracy, it is generally necessary for operators to manually clean the CCD camera lens after stopping the equipment. However, this increases the workload and is inconvenient. Therefore, the following solution is disclosed for reference. Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, it includes a frame 1 and a vibratory feeder 2. A motor is installed at the bottom inside the frame 1, and an indexing plate 3 is set on the inner wall of the frame 1 above the motor. The bottom of the indexing plate 3 is fixedly connected to the output end of the motor through a shaft. A guide rail 4 is inclinedly set between the vibratory feeder 2 and the frame 1. An industrial camera 5 is installed on the left side of the inner wall of the frame 1.

[0033] It also includes: a fixing plate 6 is fixedly connected to the right side of the top of the inner wall of the frame 1, and a nozzle is installed below the right side of the fixing plate 6; a collection box 9 is bolted to the lower right side of the frame 1; a sleeve 7 is fitted on the outer side of the shaft end of the indexing plate 3; the indexing plate 3 and the frame 1 are rotatably connected; the sleeve 7 and the frame 1 are connected by a bearing; and a ratchet assembly 21 is installed between the inner wall of the sleeve 7 and the outer side of the shaft end of the indexing plate 3; a transmission rod 14 is connected to the left side of the bottom of the inner wall of the frame 1 by a bearing; and a first pulley assembly is installed between the outer side of the lower end of the transmission rod 14 and the outer side of the sleeve 7. On the left side of the inner wall of the frame 1, below the industrial camera 5, a reciprocating screw 15 and a limiting rod 16 are connected respectively. The top end of the transmission rod 14 is connected to the outer side of the left end of the reciprocating screw 15 through a bevel gear set. The reciprocating screw 15 is connected to the inner wall of the frame 1 by a bearing. A guide plate 18 is sleeved on the outer side of the reciprocating screw 15 and the limiting rod 16. A cleaning brush 22 is provided on the top of the guide plate 18. The limiting rod 16 is fixed to the inner wall of the frame 1. The front end of the guide plate 18 is threadedly connected to the reciprocating screw 15, and the rear end of the guide plate 18 is slidably connected to the limiting rod 16.

[0034] Motorcycle screws are fed sequentially onto the indexing plate 3 via the vibrating plate 2 and guide rail 4. The motor is then started, causing the indexing plate 3 to rotate forward. The sleeve 7 remains stationary, moving the motorcycle screws sequentially below the industrial camera 5. The industrial camera 5 performs a comprehensive inspection of the motorcycle screws, counting the qualified screws. Unqualified screws are sprayed into the collection box 9 via a nozzle for sieving, thus achieving rapid and accurate sieving and counting. After counting, the motor drives the indexing plate 3 to rotate in the reverse direction, and the ratchet assembly 21 drives the sleeve 7 to rotate. The sleeve 7, via the first pulley assembly, drives the transmission rod 14 to rotate synchronously. Simultaneously, the transmission rod 14, via a bevel gear set, drives the reciprocating screw 15 to rotate, causing the guide plate 18 to move back and forth on the reciprocating screw 15. This movement of the cleaning brush 22 cleans the dust and impurities on the mirror surface of the industrial camera 5, preventing dust or impurities from affecting the accuracy of the count.

[0035] Example 2: Unlike Example 1, this example utilizes the rack 17 and driven gear 20 to rotate the cleaning brush 22 and clean the mirror surface of the industrial camera 5, thereby improving the cleaning effect. See details... Figure 2 and Figure 4As shown, each of the three cleaning brushes 22 has a rotating rod 19 bolted to its bottom, and the bottom of the rotating rod 19 passes through the interior of the guide plate 18. The outer sides of the lower ends of the three rotating rods 19 are connected to each other through a second pulley assembly. A rack 17 is fixedly connected to the inner wall of the frame 1 between the reciprocating screw 15 and the limiting rod 16. A driven gear 20 is fixed to the outer side of the rear rotating rod 19. One end of the rack 17 passes through the interior of the guide plate 18, and the rack 17 and the driven gear 20 are meshed. The cleaning brushes 22 are rotatably connected to the guide plate 18 through the rotating rods 19.

[0036] When the guide plate 18 moves back and forth, the rack 17 enables the driven gear 20 to rotate in both directions, which in turn drives the rotating rod 19 to rotate, thereby enabling the cleaning brush 22 to rotate and clean the mirror surface of the industrial camera 5, thus improving the cleaning effect.

[0037] Example 3: Unlike Example 2, this example uses gas to push the movable plate 11 upward, which can block qualified screws and prevent them from entering the collection box 9 along with unqualified screws. See details... Figure 5 and Figure 7 As shown, a support block 8 is fixed on the right side of the inner wall of the frame 1, and a receiving groove 10 is symmetrically opened on the top of the support block 8. The inner walls of the two receiving grooves 10 are slidably connected with movable plates 11. A return spring 12 is installed between the bottom of the movable plate 11 and the inner wall of the receiving groove 10. The interior of the fixed plate 6 is hollow, and the top of the fixed plate 6 is connected to the external air supply equipment through a hose. The receiving groove 10 and the fixed plate 6 are connected through a connecting pipe 13.

[0038] An external gas supply device delivers gas into the fixed plate 6 through a hose and blows the gas out through a nozzle. At the same time, a portion of the gas enters the receiving groove 10 through the connecting pipe 13 and pushes the movable plate 11 upward, thereby blocking the screws on the indexing plate 3. This prevents the nozzle from blowing unqualified screws into the collection box 9 while also blowing qualified screws into the collection box 9. When the nozzle stops blowing high-pressure gas, the movable plate 11 is reset by the elastic force of the return spring 12 and moves into the receiving groove 10.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
