Description

Technical Field

[0001] The present application relates to the field of gold plating equipment, and in particular to a transmission mechanism for gold plating equipment. Background Art

[0002] Plastic gold plating refers to a decoration method for plastic products. It is a metallization treatment on the surface of plastic products to give them a metallic luster. It is widely used in switch panels, automotive parts, home appliances and other products.

[0003] When the gold plating equipment in the related art performs gold plating on the switch panel, the switch panel is usually placed on a fixture, and then the fixture is installed on a transmission mechanism, and then the fixture and the switch panel are transported by the transmission mechanism. Subsequently, the switch panel is sprayed with paint by a spray paint device so that a layer of primer is attached to the surface of the switch panel, and then the switch panel is dried by a drying device. Subsequently, the fixture is removed from the transmission mechanism, and then the coating film is attached to the surface of the switch panel, and then the switch panel and the fixture are placed in the coating equipment together. Then, the coating equipment can perform the coating operation on the switch panel, thereby realizing the gold plating operation on the switch panel.

[0004] The transmission mechanism in the related art usually includes a workbench and two conveying gears respectively connected to the workbench in a vertical rotation, the two conveying gears are connected by a conveying chain, and a plurality of supporting rods are vertically connected to the conveying chain along its circumferential direction. When the two conveying gears drive the conveying chain to move, the conveying chain can drive the plurality of supporting rods to perform circumferential movement in the horizontal direction.

[0005] The clamp in the related art generally includes a limit frame and a support tube vertically fixedly connected to the lower end of the limit frame, and the switch panel can be inserted into the limit frame to fix the switch panel. At the same time, the support tube can be sleeved on the support rod to connect the support tube with the support rod.

[0006] When the production staff performs gold plating on the switch panel, the switch panel is inserted into the limit frame, and the switch panel is limited by the friction between the limit frame and the switch panel. Subsequently, the support tube is sleeved on the corresponding support rod, and the support tube is limited in the vertical direction by the friction between the support tube and the support rod. Then, the support rod, support tube, limit frame, switch panel and other workpieces can be transported by the conveyor chain.

[0007] In view of the above-mentioned related technologies, in order to improve the connection stability between the support rod and the support tube and reduce the risk of the support tube becoming loose, production personnel are usually required to press the limit frame so that the support rod and the support tube form a tight clamping fit. However, requiring production personnel to press each limit frame increases the workload of production personnel, which needs to be improved. Summary of the invention

[0008] In order to reduce the workload of production personnel, the present application provides a transmission mechanism for gold plating equipment.

[0009] The present application provides a transmission mechanism for gold-plating equipment that adopts the following technical solution:

[0010] A transmission mechanism for gold plating equipment includes a workbench, and also includes: two conveying gears, which are respectively connected to the upper end of the workbench in a vertical rotation; a conveying chain, which is wound around the two conveying gears and connects the two conveying gears, and the conveying chain has two straight ends and two reversing ends; a plurality of support rods, which are respectively connected to the upper ends of the conveying chains in a vertical direction, and the plurality of support rods are evenly distributed along the circumferential direction of the conveying chain; a driving member, which is fixed to the upper end of the workbench and can drive any of the conveying gears to rotate; a mounting frame, which is fixed to the upper end of the workbench and is located on the side of the straight end of the conveying chain; a clamping block, which is vertically slidably connected to the side wall of the mounting frame, and the support rod can be located below the clamping block; a driving mechanism, which is arranged between the workbench and the mounting frame and can drive the clamping block to move vertically.

[0011] By adopting the above technical solution, when the switch panel needs to be transported, the switch panel is inserted into the limit frame, and then the support tube is sleeved on the support rod. Subsequently, the corresponding conveying gear is driven to rotate by the driving member, and then the two conveying gears drive the conveying chain to drive several support rods, support tubes and switch panel components to move. When the receiving plate is located below the clamping block, the clamping block is driven to move vertically downward by the driving mechanism, and then the clamping block can press the limit frame so that the support rod and the support tube quickly form a tight clamping fit, thereby achieving the fixation of the support tube and the support rod. This design does not require production personnel to manually press the limit frame, which can not only reduce the workload of production personnel, but also improve production efficiency. At the same time, when the clamping block moves downward, the clamping block can also press the switch panel, so that the switch panel and the limit frame form a tight clamping fit, reducing the risk of the switch panel falling off, thereby improving the transportation stability of the switch panel.

[0012] Optionally, the driving mechanism includes: a driven rack vertically fixed to the lower end of the pressure block; a driving rack vertically slidably connected to the side wall of the mounting frame; a linkage gear rotatably connected to the side wall of the mounting frame, the driving rack and the driven rack are distributed on both sides of the linkage gear and are respectively meshed with the linkage gear; a control block is provided with a plurality of and respectively fixed to the side walls of the conveying chain, and the plurality of control blocks are respectively located on the sides of the corresponding support rods; a driving inclined plane is provided on the side wall of each control block; a spring is connected between the driven rack and the mounting frame and can drive the driven rack to move upward; wherein, when the driving inclined plane abuts against the lower end of the driving rack, the limit frame is located below one end of the pressure block, and when the driving rack is separated from the control block, the limit frame is located below the other end of the pressure block.

[0013] By adopting the above technical solution, when the conveying chain drives the control block to move toward the driving rack and makes the lower end of the driving inclined surface abut against the lower end of the driving rack, the limit frame is located below one end of the clamping block. As the conveying chain continues to drive the control block to move, the driving rack can then move upward under the push of the driving inclined surface. At this time, the driving rack drives the linkage gear to drive the driven rack to move, and then the driven rack can drive the clamping block to move downward, and then the clamping block can press the limit frame.

[0014] As the control block continues to move, when the control block separates from the driving rack, the limit frame is located below the other end of the clamping block. Subsequently, the driven rack drives the clamping block to move upward and reset under the elastic force of the spring, and then the linkage gear rotates in the opposite direction and causes the driven rack to move downward and reset, and this reciprocating process can realize the vertical reciprocating motion of the clamping block.

[0015] By setting a driving mechanism with a simple structure and stable driving effect, the fast movement of the pressing block is realized, thereby improving the working efficiency of pressing and fixing the support rod and the support tube, thereby improving the production efficiency. At the same time, this design can realize the automatic reciprocating motion of the pressing block, which can not only save the driving source of the pressing block, but also improve the linkage between various components and improve the efficiency of resource utilization.

[0016] Optionally, it also includes a support block fixed to the side wall of the mounting frame; a limit block fixed to the side wall of the mounting frame and located above the support block; a mounting block fixed to the side wall of the driven rack and located between the support block and the limit block; wherein the two ends of the spring are respectively connected to the mounting block and the support block, and the limit block is abutted against the mounting block.

[0017] By adopting the above technical solution, when the driving inclined plane pushes the driving rack to move upward and causes the driven rack to move downward, the mounting block moves synchronously with the driven rack and causes the spring to be gradually compressed. When the driving block is separated from the driving rack, the mounting block drives the driven rack to move upward under the elastic force of the spring, and when the mounting block abuts against the limit block, the driven rack is reset. By setting a limit block that can block the mounting block, the vertical upward movement stroke of the driven rack is limited. This design can keep the reset position of the driving rack and the driven rack as constant as possible each time, so that the driving inclined plane can abut against the specific position of the lower end of the driving rack as much as possible each time, thereby improving the driving stability of the driving inclined plane on the driving rack, and then improving the use stability of the transmission mechanism.

[0018] Optionally, it also includes a plurality of rollers arranged in parallel and rotatably connected to the lower end of the clamping block; wherein the axial direction of the roller is perpendicular to the length direction of the straight end of the conveying chain.

[0019] By adopting the above technical solution, when the pressing block moves downward and contacts the limit frame and the switch panel, there is relative sliding between the switch panel and the pressing block. By providing the roller, the friction between the switch panel and the pressing block is reduced, thereby improving the movement smoothness of components such as the switch panel. At the same time, this design can also reduce the risk of the pressing block scratching the switch panel, thereby improving the production quality of the product.

[0020] Optionally, the plurality of support rods are rotatably connected to the conveying chain respectively, and a control mechanism capable of driving the support rods to rotate is provided on the workbench.

[0021] By adopting the above technical solution, by setting a rotatable support rod, the support rod can drive the support tube, the limit frame and the switch panel to rotate. When the production personnel set the spray paint equipment on the workbench and the spray paint equipment sprays the switch panel, the rotatable switch panel allows the primer to cover the surface of the switch panel as evenly as possible, thereby further improving the production quality of the product.

[0022] Optionally, the control mechanism includes a support frame fixed to the upper end of the workbench and located on the side of the straight end of the conveying chain; a transmission gear fixedly mounted on each of the support rods; and a transmission rack horizontally fixed to the side wall of the support frame and engaged with the transmission gear.

[0023] By adopting the above technical solution, when the conveying chain drives the support rod and the corresponding transmission gear to move, and the transmission gear is meshed with the transmission rack, as the conveying chain continues to drive the support rod to move, the transmission gear can then drive the corresponding support rod to rotate under the drive of the transmission rack. When the transmission gear disengages from the transmission rack, the support rod stops rotating. By setting a control mechanism with a simple structure, convenient operation, and good driving stability, the support rod can be rotated quickly and smoothly, thereby improving the work efficiency when spraying paint on the switch panel. At the same time, this design allows the support rod to rotate automatically during the process of the conveying chain driving the support rod to move, which can not only save the driving source of the support rod, but also improve the linkage between the various components and improve the efficiency of resource utilization.

[0024] Optionally, the support frame is provided with a mounting shaft, which is vertically rotatably connected to the support frame and is located above the transmission rack; a cleaning brush is fixed to the lower end of the mounting shaft; and a control member drives the mounting shaft to rotate and makes the rotation direction of the mounting shaft opposite to the rotation direction of the support rod; wherein, when the limit frame is located below the cleaning brush, the bristles of the cleaning brush abut against the limit frame.

[0025] By adopting the above technical solution, when the transmission gear is meshed with the transmission rack, the bristles of the cleaning brush abut against the limit frame and the switch panel. At this time, the control member drives the mounting shaft to drive the cleaning brush to rotate, and then the rotating cleaning brush can clean the switch panel to achieve the dust removal capability of the switch panel. This design can reduce the risk of particles appearing on the surface of the switch panel after the switch panel is painted, so as to improve the production quality of the product. At the same time, since the cleaning brush rotates in the opposite direction to the switch panel, the cleaning effect of the cleaning brush on the switch panel is improved, thereby improving the cleanliness of the switch panel.

[0026] Optionally, the upper end of the workbench is provided with a gantry, with the open end facing and the straight end of the conveying chain located on the inner side of the gantry; two iron blocks are provided and respectively fixed to the inner walls on both sides of the gantry; a wire is wound around each of the iron blocks; a power supply is fixed to the side walls of the gantry, and the two wires are electrically connected to the power supply respectively; two permanent magnets are provided and respectively vertically slidably connected to the inner walls on both sides of the gantry, and the permanent magnets are located above the corresponding iron blocks; wherein the limit frame can be located directly above the two permanent magnets, and the magnetic poles of the iron block and the corresponding permanent magnet close to one end after power is turned on are the same.

[0027] By adopting the above technical solution, when the limit frame moves to the top of the two permanent magnets, the power is turned on and the two wires are energized, and then the two iron blocks and the corresponding wires form an electromagnet. Subsequently, the two permanent magnets can move upward under the repulsive force of the corresponding iron blocks, and then the two permanent magnets can push the limit frame to drive the support tube to move upward. When the power is turned off, the two permanent magnets can move downward and reset under the action of their own gravity. This design can realize the pre-disassembly of the support tube and the support rod, thereby loosening the support tube and the support rod, which can not only facilitate the production personnel to quickly disassemble the support tube and the support rod, but also reduce the workload of the production personnel and improve production efficiency.

[0028] Optionally, it also includes a button switch, which is fixed to an inner wall of one side of the gantry and is electrically connected to the power supply.

[0029] By adopting the above technical solution, the power on and off is controlled by using a button switch, which makes it convenient for production personnel to quickly control the power on and off, thereby improving operational convenience.

[0030] Optionally, when the upper end surface of the control block touches the button switch to turn on, the limit frame is located above the two permanent magnets.

[0031] By adopting the above technical solution, when the conveying chain drives the control block to move toward the push button switch, the driving inclined surface can push the contact of the push button switch to move upward. When the contact of the push button switch is separated from the driving inclined surface and abuts against the upper end surface of the control block, the push button switch controls the power to turn on. At this time, the limit frame is located above the two permanent magnets, and then the two permanent magnets can push the limit frame to drive the support tube to move upward. When the contact of the push button switch is separated from the control block, the push button switch controls the power to turn off, and then the permanent magnet moves downward and resets under the action of its own gravity. This design can realize the automatic control of the power on and off, which can not only improve the linkage between the various components, but also improve the efficiency of resource utilization, and reduce the workload of production personnel.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. The pressing block is driven by the driving mechanism to move vertically downward. When the limit frame is located below the pressing block, the pressing block can press the limit frame so that the support rod and the support tube quickly form a tight clamping fit to achieve the fixation of the support tube and the support rod. This design does not require production personnel to manually press the limit frame, which can reduce the workload of production personnel and improve production efficiency.

[0034] 2. By setting a driving mechanism with a simple structure and stable driving effect, the fast movement of the pressing block is realized, thereby improving the working efficiency of pressing and fixing the support rod and the support tube, thereby improving the production efficiency;

[0035] 3. By setting a rotatable support rod, the support rod can drive the support tube, the limit frame and the switch panel to rotate. When the production personnel set the paint spraying equipment on the workbench and the paint spraying equipment is spraying paint on the switch panel, the switch panel can be rotated so that the primer can cover the surface of the switch panel as evenly as possible, thereby further improving the production quality of the product.

At the same time, the lower end of the limit frame 1 is vertically fixedly connected with a support pipe 2 to facilitate connection with the transmission mechanism.

[0048] Reference Figure 2 and Figure 3 The transmission mechanism of the gold plating equipment includes a workbench 3, the upper end of the workbench 3 is vertically rotatably connected to two conveying gears 4, and the two conveying gears 4 are connected by a conveying chain 5, so that the conveying gear 4 can drive the conveying chain 5 to rotate in the horizontal direction.

[0049] Reference Figure 2 and Figure 4 A plurality of support rods 6 are vertically connected to the upper end of the conveying chain 5, and the plurality of support rods 6 are evenly distributed along the circumferential direction of the conveying chain 5, and the support rods 6 are provided for the support tube 2 to be mounted, so that the conveying chain 5 can drive the support rods 6, the support tube 2, the limit frame 1 and the switch panel to move, so as to realize the transportation capacity of the switch panel.

[0050] Reference Figure 2 and Figure 3 A driving member 7 is provided at the upper end of the workbench 3. The driving member 7 adopts a servo motor, and the output shaft of the servo motor is fixedly connected to the rotating shaft of one of the driving conveying gears 4. When the output shaft of the servo motor drives the corresponding conveying gear 4 to rotate, the conveying chain 5 can drive the plurality of support rods 6 to move. The portion of the conveying chain 5 located at the two conveying gears 4 is the reversing end, and the portion of the conveying chain 5 located between the two conveying gears 4 is the straight end.

[0051] Reference Figure 5 and Figure 6 The upper end of the workbench 3 is fixedly connected with a mounting frame 8, and the mounting frame 8 is located on the side of the straight end of the conveying chain 5. The side wall of the mounting frame 8 is vertically slidably connected with a clamping block 9, and the support rod 6 and the limit frame 1 can move to the bottom of the clamping block 9. At the same time, a driving mechanism 10 capable of driving the clamping block 9 to move vertically is arranged between the workbench 3 and the mounting frame 8.

[0052] Reference Figure 5 and Figure 6, a plurality of rollers 11 are rotatably embedded at the lower end of the pressing block 9, and the plurality of rollers 11 are parallel to each other, and the axial direction of the rollers 11 is perpendicular to the length direction of the straight end of the conveying chain 5. When the pressing block 9 moves downward and the rollers 11 abut against the switch panel and the limit frame 1, as the support rod 6 drives the support tube 2, the limit frame 1 and the switch panel to move horizontally, the rollers 11 can rotate under the drive of the limit frame 1 and the switch panel to reduce the friction between the switch panel and the pressing block 9, and also reduce the risk of the pressing block 9 scratching the switch panel.

[0053] When the conveying chain 5 drives the support rod 6, the support tube 2, the switch panel and other components to move, and the limit frame 1 is located below the pressing block 9, the pressing block 9 is driven by the driving mechanism 10 to drive the roller 11 to move vertically downward. Subsequently, the roller 11 abuts against the switch panel and the limit frame 1, and the switch panel and the pressing block 9 slide relative to each other. At this time, the roller 11 rotates while pressing the limit frame 1 and the switch panel, so that the support rod 6 and the support tube 2 quickly form a tight snap fit, thereby fixing the support tube 2 and the support rod 6. This design does not require production personnel to manually press the limit frame 1, thereby reducing the workload of production personnel.

[0054] Reference Figure 5 and Figure 6 The driving mechanism 10 includes a driven rack 101 vertically fixedly connected to the lower end of the pressing block 9, and a driving rack 102 is vertically slidably connected to the side wall of the mounting frame 8.

At the same time, a driving inclined surface 105 is integrally formed on the side wall of the control block 104, and the driving inclined surface 105 can abut against the lower end of the driving rack 102. When the conveying chain 5 drives the control block 104 to move toward the driving rack 102, the driving inclined surface 105 can push the driving rack 102 to move upward.

The mounting block 14 is connected to the support block 12 through a spring 106, and the spring 106 can drive the mounting block 14 to move upward, and at the same time, the limit block 13 is abutted by the mounting block 14 to achieve the limitation of the reset position of the mounting block 14.

[0057] When the control block 104 is separated from the driving rack 102, the spring 106 pushes the mounting block 14 to drive the driven rack 101 to move upward, and makes the mounting block 14 abut against the limit block 13. Then, the linkage gear 103 rotates and makes the driven rack 101 move downward and reset.

[0058] Reference Figure 2 and Figure 6 When the lower end of the driving inclined surface 105 just contacts the lower end of the driving rack 102, the limit frame 1 is located below one end of the pressing block 9, and when the driving rack 102 just separates from the control block 104, the limit frame 1 is located below the other end of the pressing block 9.

The side walls of the gantry 15 are fixedly connected with a power supply 18. The ends of the two wires 17 are respectively connected to the positive or negative pole of the power supply 18, so that when the power supply 18 is turned on and the two wires 17 are energized, the two iron blocks 16 and the corresponding wires 17 form an electromagnet.

When the contact of the button switch 20 is separated from the driving inclined surface 105 and abuts against the upper end surface of the control block 104, the button switch 20 controls the power supply 18 to be turned on. As the control block 104 continues to move, when the contact of the button switch 20 is separated from the control block 104, the button switch 20 controls the power supply 18 to be turned off, so as to realize the automatic control of the power supply 18 to be turned on and off.

When the production personnel set the spray paint equipment on the workbench 3 and the spray paint equipment sprays the switch panel, the switch panel can be rotated so that the primer can cover the surface of the switch panel as evenly as possible, so as to improve the production quality of the product.

At the same time, a transmission rack 212 is horizontally fixedly connected to the side wall of the support frame 211, and a transmission gear 213 that can mesh with the transmission rack 212 is fixedly sleeved on each support rod 6.

[0066] When the conveying chain 5 drives the support rod 6 and the corresponding transmission gear 213 to move, and the transmission gear 213 is meshed with the transmission rack 212, as the conveying chain 5 continues to drive the support rod 6 to move, the transmission gear 213 can then drive the corresponding support rod 6 to rotate under the drive of the transmission rack 212. As the conveying chain 5 continues to drive the support rod 6 to move, when the transmission gear 213 disengages from the transmission rack 212, the support rod 6 stops rotating.

At the same time, the rotation direction of the mounting shaft 22 is opposite to the rotation direction of the limiting frame 1, so as to improve the cleaning effect of the cleaning brush 23 on the switch panel.

[0069] The implementation principle of the transmission mechanism for a gold plating device in the embodiment of the present application is as follows: when the switch panel needs to be transported, the switch panel is inserted into the limit frame 1, and then the support tube 2 is sleeved on the support rod 6. Subsequently, the conveying gear 4 is driven by the driving member 7 to drive the conveying chain 5 to move, and then the conveying chain 5 drives the support rod 6, the control block 104, the support tube 2, the limit frame 1 and the switch panel and other components to move.

[0070] When the driving inclined plane 105 abuts against the lower end of the driving rack 102, the limiting frame 1 is located at the lower end of the side of the pressing block 9 away from the support frame 211. As the control block 104 continues to move, the driving inclined plane 105 pushes the driving rack 102 to move upward. At this time, the linkage gear 103 rotates, and then the driven rack 101 drives the pressing block 9 and the roller 11 to move downward, and the roller 11 abuts against the switch panel. At this time, the roller 11 rotates under the action of the switch panel, and at the same time, the roller 11 presses the switch panel and the limiting frame 1 to achieve rapid fixation of the support tube 2 and the support rod 6.

[0071] As the control block 104 continues to move, when the control block 104 separates from the driving rack 102, the limiting frame 1 is located at the lower end of the pressing block 9 near the support frame 211. At this time, the spring 106 drives the mounting block 14 to drive the driven rack 101 to move upward, and makes the mounting block 14 abut against the limiting block 13. Subsequently, the driven rack 101 drives the pressing block 9 and the roller 11 to move upward and reset, and at the same time, the linkage gear 103 rotates, and makes the driving rack 102 move downward and reset.

[0072] As the conveying chain 5 continues to drive the support rod 6, the control block 104, the support tube 2, the limit frame 1 and the switch panel and other components to move, when the transmission gear 213 is engaged with the transmission rack 212, the transmission gear 213 drives the corresponding support rod 6 to rotate under the drive of the transmission rack 212, and then the support rod 6 drives the support tube 2, the limit frame 1 and the switch panel to rotate. At the same time, the bristles of the cleaning brush 23 abut against the limit frame 1 and the switch panel, and then the control member 24 drives the mounting shaft 22 to drive the cleaning brush 23 to rotate, and then the rotating cleaning brush 23 can clean the switch panel. As the conveying chain 5 continues to move, when the transmission gear 213 separates from the transmission rack 212, the cleaning brush 23 separates from the limit frame 1, and the support rod 6 stops rotating.

[0073] As the conveying chain 5 continues to drive the support rod 6, the control block 104, the support tube 2, the limit frame 1 and the switch panel and other components to move, the driving inclined surface 105 pushes the contact of the button switch 20 to move upward. When the contact of the button switch 20 is separated from the driving inclined surface 105 and abuts against the upper end surface of the control block 104, the button switch 20 controls the power supply 18 to turn on. At this time, the limit frame 1 is located directly above the two permanent magnets 19. Subsequently, the two permanent magnets 19 can move upward under the repulsive force of the corresponding iron block 16, and then the two permanent magnets 19 can push the limit frame 1 to drive the support tube 2 to move upward, so as to realize the pre-disassembly operation of the support rod 6 and the support tube 2.

[0074] As the conveying chain 5 continues to move, when the contact of the button switch 20 separates from the control block 104, the button switch 20 controls the power supply 18 to turn off, and then the permanent magnet 19 moves downward and resets under the action of its own gravity. In this way, the switch panel can be transported.

[0075] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
