[0035] Furthermore, the power unit 4 includes an L-shaped bracket 7, a drive shaft 8 is rotatably mounted on the horizontal plate of the L-shaped bracket 7, a first pulley 9 is fixedly mounted on the upper part of the drive shaft 8, the lower end of the connecting shaft 3 extends to the lower part of the base 1 and a second pulley 10 is fixedly mounted thereon, and the second pulley 10 is connected to the first pulley 9 through a belt 11.

[0036] Furthermore, the first pulley 9 and the second pulley 10 are synchronous pulleys, and the belt 11 is a synchronous belt.

[0037] Furthermore, a pressure wheel 12 is rotatably installed on the outer side of the belt 11 on the bottom surface of the base 1 between every two second belt pulleys 10;

[0038] A tensioning wheel 13 is rotatably mounted on the outer side of the belt 11 between the first pulley 9 and the second pulley 10 on the bottom surface of the base 1.

[0039] Furthermore, the lower end of the drive shaft 8 extends through the horizontal plate of the L-shaped bracket 7 to the lower part of the horizontal plate and is fixedly mounted with the first magnetic coupling member 14.

[0040] Furthermore, the clamping shaft 2 includes a plastic rod 21 and a metal sleeve 22. The plastic rod 21 is fixedly connected to the metal sleeve 22, and the metal sleeve 22 is disposed on the outer circumference of the lower part of the plastic rod 21.

[0041] Furthermore, a pin 16 is provided at the top of the connecting shaft 3. The pin 16 includes a pin seat 17 and a pin head 18. At least one magnet 19 is fixedly provided on the annular upper surface of the pin seat 17 along the circumferential direction.

[0042] The plastic rod 21 has a hollow structure. The lower end of the plastic rod 21 is sleeved on the pin head 18. The metal sleeve 22 is attracted by the magnet 19, causing the clamping shaft 2 to be attracted to the pin 16.

[0043] Furthermore, the cavity inside the plastic rod 21 is connected to the opening 25 located at the upper end of the plastic rod 21;

[0044] A vent hole 24 is provided on the outer circumference of the lower part of the plastic rod 21, and the vent hole 24 is connected to the cavity inside the plastic rod 21.

[0045] The working principle of the above technical solution:

[0046] Because the workpiece needs to go through multiple processes during spraying, the pretreatment process removes dust and oil stains from the workpiece surface, the surface treatment process improves the affinity between the workpiece surface and the coating, such as roughening, the primer process sprays primer onto the workpiece surface, the metallization process performs vacuum coating on the workpiece surface, and the topcoat process sprays protective paint onto the coated workpiece surface. Each spraying process has spraying and drying stations. If all stations are set on the conveyor belt of the production line, it will result in a large floor space, fixed processes, inflexible process settings, and difficulty in adjusting process parameters. Therefore, a modular assembly production line is needed to solve the above problems. One work unit of the modular assembly production line corresponds to one processing operation, which requires the workpiece to be able to be transferred between different work units. The detachable clamping shaft 2 can transfer the workpiece together. When transferring the workpiece, only the clamping shaft needs to be clamped, without touching the workpiece, to prevent scratches on the workpiece surface and affect the surface treatment quality. The work slide only circulates within the work unit, effectively reducing the pollution of upstream processing operations to downstream work units.

[0047] Multiple connecting shafts 3 are arranged in a linear array along the length of the base 1. Each connecting shaft has a clamping shaft 2 on its upper part, allowing multiple workpieces 100 to be installed simultaneously, thus improving the efficiency of the spraying operation. A support base 5 is provided on the base 1, with the lower end of the support base 5 penetrating through the base 1. The lower end of the connecting shaft 3, which is rotatably mounted inside the support base 5, extends to the lower part of the base 1 and is fixedly connected to a second pulley 10. The second pulley 10 is connected to the first pulley 9 via a belt 11. A first magnetic coupling element 14 is fixedly mounted on the lower end of the transmission shaft 8. The base 1 is connected by sliders 23 that are oppositely arranged on the bottom surface. The base is mounted on a guide rail 103 on the worktable 102. A second magnetic coupling element 104 is mounted on the worktable 102, corresponding to the first magnetic coupling element 14. When the base moves to the spraying station on the worktable 102, it stops. At this time, the first magnetic coupling element 14 and the second magnetic coupling element 104 are opposite each other. The second magnetic coupling element 104 is fixedly connected to the output shaft of the motor fixed on the worktable 102. After the motor starts, it drives the first magnetic coupling element 14 to rotate through the second magnetic coupling element 104. Through the transmission mechanism, it drives the clamping shaft 2 to rotate, thereby driving the workpiece to rotate and making the workpiece sprayed more evenly.

[0048] The first pulley 9 and the second pulley 10 are synchronous pulleys, the belt 11 is a synchronous belt, and the tensioning wheel 13 is used to tension the belt to prevent slippage and avoid uneven spraying caused by different workpiece rotation speeds. The pressure wheel 12 can increase the contact length between the belt 11 and the second pulley 10, which also plays the role of preventing slippage.

[0049] To improve the rotational stability of the connecting shaft 3, a support seat 5 is provided on the base 1. Rotary connectors 6 are respectively installed at the upper and lower ends of the support seat 5. The outer ring of the rotary connector 6 is connected to the inner hole of the support seat 5, and the inner ring of the rotary connector 6 is connected to the outer circumference of the connecting shaft 3. The rotary connector 6 can be a bearing. The bearing can be selected from general-purpose bearings that are suitable for the size of the support seat. The installation method of the bearing is common knowledge and will not be described in detail here. When the workpiece speed is low, a nylon bushing can be used for the rotary connector 6. The outer circumference of the nylon bushing is interference-fitted with the inner hole of the support seat 5, and the outer circumferential surface of the connecting shaft 3 is rotatably fitted with the inner circumferential surface of the nylon bushing. The nylon bushing can be customized, such as by Jingxian Duqiao Qiangze Super Wear-resistant Plastic Products Factory, based on the inner hole size of the support seat 5 and the shaft diameter of the connecting shaft 3.

[0050] A sealing sleeve 15 is fixedly installed on the top of the support base 5. When the connecting shaft 3 rotates, the sealing sleeve 15 is tightly fitted on the outer circumference of the connecting shaft 3. The connecting shaft 3 and the sealing sleeve rotate to prevent dust and sprayed paint from entering the support base and affecting the service life of the rotating connector 6.

[0051] The clamping shaft 2 includes a plastic rod 21 and a metal sleeve 22. The plastic rod 21 is fixedly connected to the metal sleeve 22, and the metal sleeve 22 is disposed on the outer circumference of the lower part of the plastic rod 21.

[0052] A pin 16 is provided at the top of the connecting shaft 3. The pin 16 includes a pin seat 17 and a pin head 18. At least one magnet 19 is fixedly provided on the annular upper surface of the pin seat 17 along the circumferential direction. The plastic rod 21 is sleeved on the pin head 18. The metal sleeve 22 is attracted by the magnet 19, causing the clamping shaft 2 to be attracted to the pin 16.

[0053] A connecting hole is made on the bottom surface of the pin seat 17. The upper end of the connecting shaft 3 is inserted into the connecting hole. A screw hole is made on the side wall of the connecting hole. The screw hole is threaded with a set screw 20. After the pin seat 17 is connected to the connecting shaft, the set screw 20 is tightened so that the end of the set screw 20 near the connecting shaft 3 presses against the outer wall of the connecting shaft 3, so that the pin seat 17 and the connecting shaft 3 are connected together. The pin 16 can rotate with the connecting shaft 3.

[0054] The metal sleeve 22 is made of steel or iron and can be attracted by the magnet 19. When the clamping shaft 2 is fitted onto the pin 16, the metal sleeve 22 is attracted by the magnet 19. The lower end face of the metal sleeve 22 contacts the annular upper end face of the pin seat 17, thereby making the clamping shaft 2 stably set on the pin 16. When the pin 16 rotates, it drives the clamping shaft 2 to rotate. The upper end of the plastic rod 21 of the clamping shaft 2 has a cross-shaped opening. When the workpiece 100 is fitted onto the plastic rod 21, it squeezes the upper end of the plastic rod 21. Under the action of the elastic force, the upper end of the plastic rod 21 makes the workpiece 100 and the plastic rod 21 fit tightly. The plastic rod 21 can be made of engineering plastic, such as POM (polyoxymethylene).

[0055] The plastic rod 21 has a hollow structure. The lower end of the plastic rod 21 is fitted onto the pin head 18. The pin head 18 is cylindrical with a conical upper end, which facilitates the insertion of the plastic rod 21. The shape of the cavity of the plastic rod 21 is adapted to the shape of the pin head 18. The inner cavity of the plastic rod 21 and the pin head 18 are positioned by circumference, which improves the positioning accuracy. The outer circumference of the plastic rod 21 is positioned with the workpiece. The workpiece and the plastic rod 21 are tightly fitted and are not easy to loosen. The workpiece and the plastic rod 21 are coaxial, with high positioning accuracy, which is suitable for high-speed rotation of the workpiece. The workpiece will not fall off the plastic rod 21.

[0056] The cavity inside the plastic rod 21 is connected to the opening 25 at the upper end of the plastic rod 21. The opening 25 can be set as a cross-shaped opening. The upper end of the plastic rod 21 is hollow and divided into multiple elastic pieces by the opening 25, which can elastically support the workpiece.

[0057] A vent hole 24 is provided on the outer circumference of the lower part of the plastic rod 21. The vent hole 24 is connected to the cavity inside the plastic rod 21. At least one vent hole 24 is provided so that the gas inside the workpiece can be discharged when the workpiece is put on the plastic rod 21, which facilitates the workpiece being put on.

[0058] The beneficial effects of the above technical solution are as follows:

[0059] The work slide of this utility model has a connecting shaft rotatably mounted on the base, and a clamping shaft detachably mounted at the top of the connecting shaft. The workpiece can be separated from the base along with the clamping shaft, which facilitates workpiece transfer. The workpiece is fitted onto the clamping shaft, and the circumferential positioning of the clamping shaft makes it less prone to loosening and provides high positioning accuracy, which is suitable for high-speed workpiece rotation. When transferring the workpiece, the detachable clamping shaft can transfer the workpiece along with it.
