Description

Technical Field

[0001] This utility model relates to the field of adjustable wrench manufacturing technology, specifically to an automated device for applying a rubber sleeve to the handle of an adjustable wrench. Background Technology

[0002] Adjustable wrenches are indispensable tools in various industries (such as assembly, repair, and installation), primarily used for tightening hexagonal screws and nuts with considerable force. To ensure operator comfort, the handle of an adjustable wrench needs a rubber sleeve. To ensure stability when the sleeve is fitted into the wrench, the tail of the adjustable wrench is enlarged. However, this enlarged tail leads to the following problem when the sleeve is fitted:

[0003] 1. The rubber sleeve is made of soft plastic and needs to be heated before it can be put on manually. However, heating the rubber sleeve changes the properties of the material, and the handle of the rubber sleeve may become loose after it is put on.

[0004] Second, manual production increases the labor intensity and safety of workers. At the same time, the high labor intensity of rubber sleeve and handle work, and the long duration of sleeve work, affects production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automated device for the rubber sleeve handle of an adjustable wrench that is structurally reasonable and safe and reliable in operation, in light of the above-mentioned technical status.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automated device for attaching a rubber sleeve to an adjustable wrench, characterized in that it includes a four-station rotating disk, an automatic robot arm, a conveyor belt, and a control system. The four-station rotating disk is rotatably mounted on a workbench. A motor driving the four-station rotating disk is provided below the workbench. Four stations are arranged at intervals along the circumference of the four-station rotating disk. Each station is equipped with a lifting cylinder for fixing the adjustable wrench. The first station is the loading station, where the adjustable wrench is placed into the first station by the automatic robot arm. The second station is the positioning station, where the lifting cylinder moves downward to fix the adjustable wrench. The third station is the sleeve-attaching station. A fifth station is provided on the workbench corresponding to the third station. The rubber sleeve is conveyed to the fifth station by the conveyor belt. A first cylinder for fixing the rubber sleeve is provided on the fifth station. A second cylinder on the workbench pushes the fifth station forward to attach the rubber sleeve to the adjustable wrench. The fourth station is the unloading station, where the lifting cylinder moves upward and the adjustable wrench with the sleeve attached is removed by the automatic robot arm.

[0007] As an improvement, each station on the four-station rotary table is provided with two positioning slots side by side for placing two adjustable wrenches. The two adjustable wrenches are placed in the corresponding positioning slots, with the handles of the adjustable wrenches extending out of the station. There are two corresponding lifting cylinders on each station, which are installed directly above the positioning slots.

[0008] Furthermore, the workbench is provided with a track for the fifth station to move back and forth. The fifth station has two positioning points arranged side by side for placing two rubber sleeve handles. After the rubber sleeve handles are positioned at the fifth station, they correspond to the handles of the adjustable wrenches at the third station.

[0009] Furthermore, there are two conveyor belts, one on the left and one on the right, respectively, located on the left and right sides of the fifth work station. The rubber sleeve handle is fed into the conveyor belt through a circular vibrating plate and an infrared sensor, and the end of the conveyor belt corresponds to the positioning point on the fifth work station.

[0010] Furthermore, the second cylinder is positioned on the workbench at the rear of the fifth station, with the working end of the second cylinder abutting against the rear end of the fifth station.

[0011] Furthermore, the automation device also includes an inspection mechanism, which includes an inspection conveyor belt, a non-conforming product conveyor belt, and a vision detector. The non-conforming product conveyor belt is located on one side of the rear of the inspection conveyor belt and is perpendicular to the inspection conveyor belt. On the other side of the middle and rear of the inspection conveyor belt, there is a third cylinder that pushes the non-conforming products out of the inspection conveyor belt. The non-conforming products detected by the vision detector are pushed out to the non-conforming product conveyor belt by the third cylinder, and the qualified products are taken off by the automatic robot arm at the end of the inspection conveyor belt.

[0012] Furthermore, the visual detector is equipped with a display screen that shows the counts of qualified and unqualified products. The control system includes a control panel and push-button switches on the workbench.

[0013] Furthermore, the lifting cylinder, the first cylinder, the second cylinder, and the third cylinder are pneumatic or hydraulic devices; the conveyor belt, the inspection conveyor belt, and the defective product conveyor belt are driven by chain or synchronous belt.

[0014] Finally, four workstations are evenly spaced along the circumference of the four-station rotary table.

[0015] Compared with existing technologies, the advantages of this invention are as follows: It features a four-station rotary table, an automatic robotic arm, a conveyor belt, and a control system. The rotary table moves the adjustable wrench from the first station to the fourth station, completing the assembly of a rubber sleeve handle. The handle is conveyed by the conveyor belt, and the assembled product enters the inspection conveyor belt. A vision detector checks for defects such as oil stains on the product surface and improper installation of the rubber sleeve handle. Defective products are ejected by a third cylinder and placed on a defective product conveyor belt. The vision detector has a counting display screen for easy counting of qualified and defective products. The control system uses a PLC to send commands to the motors and cylinders, controlling the entire production process. This invention has a reasonable structure, is convenient and safe to operate, and represents a leap from manual to automated operation of the adjustable wrench handle, greatly increasing production efficiency while improving production safety and reliability.

[0021] like Figures 1-4As shown, an automated device for attaching a rubber sleeve to an adjustable wrench includes a four-station rotary table 1, an automatic robotic arm, a conveyor belt 3, an inspection mechanism, and a control system. The four-station rotary table 1 is rotatably mounted on a workbench 2. A motor 6 is located below the workbench 2 to drive the rotation of the four-station rotary table 1. Four stations 11, 12, 13, and 14 are evenly spaced along the circumference of the four-station rotary table 1. Each station 11, 12, 13, and 14 is equipped with a lifting cylinder 10 for fixing the adjustable wrench 20. The first station 11 is the loading station, where the adjustable wrench 20 is placed into the machine by the automatic robotic arm. The first station 11 and the second station 12 are positioning stations. The lifting cylinder 10 moves down to fix the adjustable wrench 20. The third station 13 is the handle-fitting station. The fifth station 4 is located on the worktable 2 corresponding to the position of the third station 13. The rubber handle 30 is transported to the fifth station 4 by the conveyor belt 3. The fifth station 4 is equipped with a first cylinder 40 to fix the rubber handle 30. The worktable 2 is equipped with a second cylinder 5 to push the fifth station 4 back and forth and fit the rubber handle 30 into the adjustable wrench 20. The fourth station 14 is the unloading station. The lifting cylinder 10 moves up and the adjustable wrench 20 after the handle is fitted is removed by an automatic robot arm.

[0022] The specific structure is as follows: Each of the four workstations 11, 12, 13, and 14 on the four-station rotary table 1 has two positioning slots 15 arranged side-by-side for placing two adjustable wrenches 20. The two adjustable wrenches 20 are placed in their corresponding positioning slots 15, with the handles of the adjustable wrenches 20 extending out of the workstation. Two lifting cylinders 10 are installed on each of the workstations 11, 12, 13, and 14, respectively, directly above the positioning slots 15. The workbench 2 has a track 21 for the fifth workstation 4 to move back and forth. The fifth workstation 4 has two positioning points arranged side-by-side for placing two rubber sleeve handles 30. After being positioned at the fifth workstation 4, the rubber sleeve handles 30 correspond to the handles of the adjustable wrenches 20 on the third workstation 13.

[0023] The process flow for the fifth station, 4 sets of rubber sleeve handles, 30 is as follows: Figure 3 As shown, specifically: (a) the rubber sleeve handle 30 at the end of the conveyor belt 3 enters the fifth station 4, and the first cylinder 40 moves downward to fix the rubber sleeve handle 30; (b) the second cylinder 5 pushes the fifth station 4 forward to align with the third station 13, and puts the rubber sleeve handle 30 into the handle of the adjustable wrench 20; (c) the lifting cylinder 10 moves upward to release the adjustable wrench 10 with the rubber sleeve handle 30 installed; (d) the first cylinder 40 and the second cylinder 5 automatically return to their positions, the fifth station 4 returns to its position, and the rubber sleeve handle 30 on the conveyor belt 3 enters the fifth station 4, and the above steps are repeated.

[0024] There are two conveyor belts 3, one on the left and one on the right, respectively, located on the left and right sides of the fifth station 4. The rubber sleeve handle 30 is fed into the conveyor belt 3 through a circular vibrating plate and an infrared sensor. The end of the conveyor belt 3 corresponds to the positioning point on the fifth station 4. The second cylinder 5 is located on the worktable 2 at the rear of the fifth station 4, and the working end of the second cylinder 5 abuts against the rear end of the fifth station 4.

[0025] The inspection mechanism includes an inspection conveyor belt 8, a non-conforming product conveyor belt 9, and a vision detector 70. The non-conforming product conveyor belt 9 is located on one side of the middle and rear part of the inspection conveyor belt 8 and is perpendicular to the inspection conveyor belt 8. On the other side of the inspection conveyor belt 8, there is a third cylinder 60 that ejects non-conforming products from the inspection conveyor belt 8. Non-conforming products detected by the vision detector 70 are ejected to the non-conforming product conveyor belt 9 by the third cylinder 60. Conforming products are removed from the end of the inspection conveyor belt 8 by an automatic robotic arm. The vision detector 70 can detect defects such as oil stains on the product surface and improper installation of rubber sleeve handles. The vision detector 70 is equipped with a display screen that displays the count and statistics of conforming and non-conforming products. The control system includes a control panel, and the workbench 2 is equipped with push-button switches 50.

[0026] In this embodiment, the lifting cylinder 10, the first cylinder 40, the second cylinder 5, and the third cylinder 60 are pneumatic devices, but hydraulic devices can also be used; the conveyor belt 3, the inspection conveyor belt 8, and the defective product conveyor belt 9 are chain drives, but synchronous belt drives can also be used.

[0027] The working principle is as follows:

[0028] Adjustable wrench 20 is placed in a turnover box and then automatically moved to the first station 11 of the four-station rotating disk 1 by an automated robotic arm. After entering the second station 12, the lifting cylinder 10 descends to fix the adjustable wrench 20. After entering the third station 13, it is conveyed by the conveyor belt 3 to the fifth station 4, where the rubber sleeve handle 30 is fitted onto the handle of the adjustable wrench 20 by the third cylinder 5. Finally, at the fourth station 14, the lifting cylinder 10 moves upward, and the finished product is removed by the automated robotic arm and placed into the inspection conveyor belt 8. After being inspected by the vision detector 70, defective products are ejected by the third cylinder 60 and enter the defective product conveyor belt 9, while qualified products continue to flow to the qualified product area via the inspection conveyor belt 8. Since the vision detector 70 has a counting function, the display screen can automatically display the count of qualified and defective products, facilitating statistics.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
