Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically to a polishing equipment for parts used in the production of alarm devices. Background Technology

[0002] An alarm is an electronic device that uses sound, light, air pressure, particles, or other means to alert or warn people to take certain actions in order to prevent or mitigate the consequences of an event. Alarms are divided into mechanical alarms and electronic alarms. With technological advancements, mechanical alarms are increasingly being replaced by advanced electronic alarms. Electronic alarms are frequently used in areas such as system failure detection, security, transportation, medical rescue, emergency disaster relief, and sensor detection, and are inextricably linked to social production.

[0003] Polishing equipment, also known as polishing machines or grinding machines, is a high-efficiency, intelligent surface treatment device. It is mainly used for grinding, polishing, and deburring workpiece surfaces. Polishing equipment uses a rotating grinding head to grind and polish the workpiece surface, improving its smoothness and flatness. It is widely used in manufacturing, metal processing, decoration, optoelectronics, mold processing, semiconductor manufacturing, and many other fields. The main working components of polishing equipment are a motor-driven grinding wheel or sandpaper that rotates. Common alarm housings are usually composed of a combination of hollow cylinders and hollow hemispheres. Polishing the alarm housing creates a smooth protective layer on its surface, reducing the corrosive effects of the external environment, such as reducing dust and dirt adhesion, improving the housing's wear resistance and corrosion resistance, and thus extending the alarm's service life.

[0004] In existing technologies, to improve the appearance and smoothness of polished workpieces, a lower-grit sandpaper or grinding wheel is typically used for initial surface treatment, followed by further polishing with higher-grit sandpaper. This process requires sandpaper replacement. However, existing technologies usually involve stopping the polishing process and manually replacing the sandpaper, which reduces the efficiency of the polishing process. Therefore, this method does not meet current needs. To address this, we propose a polishing equipment for alarm device manufacturing parts. Summary of the Invention

[0019] The present invention has the following beneficial effects:

[0020] 1. The polishing equipment for alarm components uses a tilting head device to drive the first fixed shaft on one side of the support rod near the polishing assembly to rotate. Since the first fixed shaft is fixedly connected to the second fixed shaft via the first fixed rod, the swing of the first fixed shaft can drive the second fixed shaft and the conveyor belt located there to rotate slightly upward around the first fixed shaft until they contact the hook and loop fastener. This causes the rough side of the sandpaper on the conveyor belt to stick to the hook and loop fastener. Because the hook and loop fastener is driven by the polishing motor to rotate, it continuously detaches from the conveyor belt. Under the contact between the conveyor belt and the hook and loop fastener, the rough sandpaper on the conveyor belt sticks to the hook and loop fastener. Through this design, the rough sandpaper can be replaced for more precise polishing of the workpiece.

[0021] 2. The polishing equipment for the parts used in the production of this alarm device has two piston chambers located on both sides below the conveyor belt, connected by positioning rods and fixed to the base plate by two fixing rods. As the sliding plate slides upwards, it drives the transmission piston plate, fixed to the sliding plate, to slide upwards synchronously. The sliding of the transmission piston plate compresses the hydraulic oil in the second piston chamber, and through the transmission hose, drives the T-shaped piston plate in the first piston chamber to slide upwards. This, in turn, drives the arc-shaped plate installed at one end of the T-shaped piston plate to slide upwards. Since the first piston chamber is installed on both sides of the second fixed shaft, it rotates synchronously with the rotation of the second fixed shaft. Therefore, the arc-shaped plate slides upwards relative to the second fixed shaft. The arc-shaped plate is located between the second transmission shaft and the conveyor belt. Therefore, the upward sliding of the arc-shaped plate drives one end of the conveyor belt to further tilt upwards, thus ensuring the contact strength between the rough sandpaper and the hook-and-loop fastener on the conveyor belt and preventing the rough sandpaper from falling off during the polishing process.

[0022] 3. In the polishing equipment for parts used in the production of this alarm device, when the sliding plate rises, the lifting rod located on the upper surface of the right-angled trapezoidal rod slides upward simultaneously, thereby driving the sliding plate to squeeze the space inside the water tank. As the space inside the water tank decreases, and one-way valves are installed in the water outlet and water inlet pipes, the water in the water tank will quickly spray out through the water outlet pipe, achieving a pressurization effect. The pressurized water flow will wash away the debris that is difficult to wash away from the workpiece. At the same time, the intermittent design ensures that the workpiece is not subjected to water flow for a long time. Through this design, the surface debris of the workpiece is cleaned while ensuring the stability of the workpiece. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1 aims to address the problem in existing technologies where changing sandpaper typically requires stopping the polishing process and manually replacing the sandpaper, thus reducing the efficiency of the polishing process. Please refer to [link to relevant documentation]. Figures 1 to 13 A polishing and grinding equipment for alarm device manufacturing components includes a base plate 1, a polishing and grinding device 2 installed on the side wall of the base plate 1, and a polishing and grinding motor 21 fixedly installed on the side wall of the base plate 1. The output end of the polishing and grinding motor 21 is fixedly connected to a polishing and grinding assembly 22.

[0039] The polishing assembly 22 includes a hard wheel 221, a sponge 222 is fixedly connected to the outer wall of the hard wheel 221, a hook-and-loop fastener 223 is installed on the outer wall of the sponge 222, and a rough sandpaper 224 is installed on the smooth side of the hook-and-loop fastener 223. The rough sandpaper 224 is used to process the workpiece 23.

[0040] The polishing assembly 22 is composed of a hard wheel 221, a sponge 222, hook and loop fasteners 223, and rough sandpaper 224. To facilitate the replacement of the rough sandpaper 224, the sponge 222 is used as a cushioning material to prevent excessive contact force between the rough sandpaper 224 and the workpiece 23, which could damage the workpiece 23. The presence of the sponge 222 also facilitates the removal of the rough sandpaper 224 from the hook and loop fasteners 223 by the disassembly device 5. The composition of the polishing assembly 22 is described in reference [reference needed]. Figure 2 .

[0041] A sandpaper conveying device 3 is provided below the polishing assembly 22. The sandpaper conveying device 3 includes a support rod 31 installed on the upper surface of the base plate 1. A first fixed shaft 32 is rotatably connected to one side of the support rod 31 near the polishing assembly 22 via a torsion spring. A first fixed shaft rod 38 is fixedly connected to one side of the support rod 31 away from the polishing assembly 22. A first fixed rod 34 is fixedly connected to both ends of the first fixed shaft 32 near the polishing assembly 22. A second fixed shaft 35 is fixedly connected to the other end of the first fixed rod 34. A first drive shaft 33 is rotatably connected to the outer wall of the first fixed shaft 32 and the first fixed shaft rod 38. A second drive shaft 36 is rotatably connected to the outer wall of the second fixed shaft 35. A conveyor belt 37 is provided on the outer wall of the first drive shaft 33 and the second drive shaft 36.

[0042] A rough sandpaper 224 is placed on the conveyor belt 37.

[0043] When it is necessary to replace the rough sandpaper 224, the rough sandpaper 224 on the hard wheel 221 is first removed by driving the disassembly device 5. Then, the end of the conveyor belt 37 with the rough sandpaper 224 is lifted by driving it, so that the rough surface of the rough sandpaper 224 comes into contact with the component of the hook and loop fastener 223. Then, by rotating the hard wheel 221, the rough surface of the rough sandpaper 224 and the hook surface of the hook and loop fastener 223 are bonded together. With this design, the sandpaper can be replaced without stopping the polishing process.

[0044] The conveyor belt 37 is used to transport rough sandpaper 224. Driven by the lifting device 4, it drives the first fixed shaft 32 on one side of the support rod 31 near the polishing assembly 22 to rotate. Since the first fixed shaft 32 is fixedly connected to the second fixed shaft 35 through the first fixed rod 34, the swing of the first fixed shaft 32 can drive the second fixed shaft 35 and the conveyor belt 37 located there to rotate slightly upward around the first fixed shaft 32 until they contact the hook Velcro 223, thereby driving the position... The rough surface of the rough sandpaper 224 on the conveyor belt 37 is bonded to the hook surface of the hook hook fastener 223. Because the hook hook fastener 223 is driven by the polishing motor 21 to rotate, it continuously detaches from the conveyor belt 37. Under the contact between the conveyor belt 37 and the hook hook fastener 223, the rough sandpaper 224 on the conveyor belt 37 is bonded to the hook hook fastener 223. Through this design, the rough sandpaper 224 can be replaced for more precise polishing of the workpiece 23.

[0045] A torsion spring is used to connect the first fixed shaft 32 and the support rod 31 to ensure that the first fixed rod 34 can be in a horizontal state under normal conditions.

[0046] The workpiece 23 is mounted on the outer side wall of the mounting shaft 24. The mounting shaft 24 is mounted on the output end of the rotary motor 25. The rotary motor 25 is mounted on one side of the slider 26. The slider 26 is slidably connected in the track 27. An electric push rod 28 is provided on the side of the slider 26 away from the rotary motor 25. The track 27 is fixedly connected to the worktable 29. The electric push rod 28 is mounted on the worktable 29.

[0047] The bottom of the worktable 29 is fixedly connected to a rotating shaft 210 and a balance bar 212. The bottom of the rotating shaft 210 is fixedly connected to an active motor 211, and the bottom of the balance bar 212 is equipped with ball bearings 213.

[0048] The workpiece 23 is polished by the rotating polishing assembly 22. For polishing a hemispherical shell, the workpiece 23 needs to be rotated at a certain angle with the contact point between the workpiece 23 and the polishing assembly 22 as the axis to complete the polishing of the arc surface.

[0049] The rotary motor 25 is used to drive the workpiece 23 to rotate. Through cooperation with the drive motor 211, it ensures that every angle of the workpiece 23 is polished. The slider 26, the track 27 and the electric push rod 28 are designed to replace different workpieces 23. At the same time, they can be adjusted according to the different lengths of the workpiece 23. The drive motor 211 and the rotating shaft 210 are designed to drive the workpiece 23 to rotate around the polishing point as the axis, so as to complete the polishing of the spherical surface.

[0050] Since the worktable 29 is only supported by the rotating shaft 210, the worktable 29 is in an unstable state. The design of the balance bar 212 can ensure that the worktable 29 is in a balanced state, and the design of the ball bearing 213 can ensure that the balance bar 212 slides more smoothly during the sliding process.

[0051] The bottom of the conveyor belt 37 is provided with a lifting device 4, which includes a first gear 41. The first gear 41 is fixedly connected to the outer wall of the first fixed shaft 32 at the rotatable connection with the support rod 31. The first gear 41 is meshed with a rack 42. The bottom end of the rack 42 is fixedly connected to the sliding plate 43. Limiting blocks 44 are fixedly connected to both sides of the sliding plate 43. The limiting blocks 44 are slidably connected in the limiting groove 45. The limiting groove 45 is opened on the inner wall of the support rod 31 near the polishing assembly 22.

[0052] A return spring 46 is fixedly connected to the bottom of the sliding plate 43. The other end of the return spring 46 is fixedly connected to the fixed plate 47. The fixed plate 47 is fixedly connected to the inner side of the support rod 31. A right-angled trapezoidal rod 48 is fixedly connected to one side of the sliding plate 43. The inclined surface of the right-angled trapezoidal rod 48 abuts against an L-shaped drive plate 49. The L-shaped drive plate 49 is fixedly connected to the bottom of the worktable 29.

[0053] The first fixed shaft 32, rotatably connected within the support rod 31, rotates via the tilting device 4. When the rotating shaft 210 drives the worktable 29 to rotate to the level of the conveyor belt 37, the L-shaped drive plate 49 at the bottom of the worktable 29 abuts against the inclined surface of the right-angled trapezoidal rod 48. At this time, the right-angled trapezoidal rod 48 and the sliding plate 43 fixedly connected to it slide upward under the drive of the L-shaped drive plate 49, thereby driving the rack 42 mounted on the sliding plate 43 to slide upward synchronously. Since the rack 42 meshes with the first gear 41, which is fixedly connected to the first fixed shaft 32, the upward sliding of the sliding plate 43 can drive the support rod 31 to rotate at a certain angle. Since the first fixed shaft 32 is fixedly connected to the second fixed shaft 35 via the first fixed rod 34... Next, the second fixed shaft 35 will be lifted. At this time, the conveyor belt 37 located at the second fixed shaft 35 and the rough sandpaper 224 placed on the conveyor belt 37 will lift up simultaneously and come into contact with the hook and loop fastener 223. Since the polishing motor 21 continuously drives the hook and loop fastener 223 to rotate, the glued rough sandpaper 224 will be glued to the hook and loop fastener 223 under the rotation of the hook and loop fastener 223 and the resistance of the conveyor belt 37. During the lifting of the conveyor belt 37, the disassembly device 5 completes the removal of the rough sandpaper 224 on the polishing motor 21. Through this design, the rough sandpaper 224 can be replaced quickly, and the replacement work is completed without stopping the polishing process, which greatly improves the polishing efficiency.

[0054] The design of the limiting block 44 and the limiting groove 45 ensures the stability of the sliding plate 43 as it slides upward. The fixed plate 47 provides support for the connection of the reset spring 46, which is used to drive the sliding plate 43 to reset.

[0055] A disassembly device 5 is provided on one side of the first gear 41 near the base plate 1. The disassembly device 5 includes a second gear 51 that meshes with the first gear 41. The second gear 51 is rotatably connected inside the connecting shaft 52. The other end of the connecting shaft 52 is fixedly connected to the base plate 1. A connecting rod 53 is fixedly connected to one side of the connecting shaft 52. A disassembly rod 54 is fixedly connected to the other end of the connecting rod 53. A disassembly rod 55 is rotatably connected to the outer wall of the disassembly rod 54.

[0056] During the process of the conveyor belt 37 tilting up, the first gear 41 rotates at a certain angle under the drive of the rack 42. At this time, the second gear 51, which is also meshed with the first gear 41, starts to rotate synchronously. The rotation of the second gear 51 drives the connecting rod 53, which is fixedly connected to it, to rotate synchronously. Since the connecting rod 53 is equipped with a disassembly rod 54 and a disassembly roller 55, the rotation of the first gear 41 drives the disassembly roller 55 to apply a resistance force to the polishing assembly 22. Since the polishing assembly 22 contains a sponge 222, and the sponge 222 has great compressibility, the sponge 222 is squeezed and deformed by the disassembly roller 55. The rough sandpaper 224 on the sponge 222 is... Figure 2 As shown, due to the pressure of the disassembly roller 55, when one end of the rough sandpaper 224 rotates to the disassembly roller 55, the rough sandpaper 224 on the hook-and-loop fastener 223 will be removed from the hook-and-loop fastener 223 by the insertion of the disassembly roller 55. At this time, with the intervention of the robotic arm, the rough sandpaper 224 on the hook-and-loop fastener 223 can be quickly removed so that the new rough sandpaper 224 can be glued to the hook-and-loop fastener 223.

[0057] The disassembly roller 55 is rotatably connected to the disassembly rod 54 to prevent the rotation of the hard wheel 221 from being obstructed due to the contact between the disassembly roller 55 and the hard wheel 221, thereby affecting the service life of the polishing motor 21.

[0058] Example 2 aims to address the potential issue of weak adhesion between the hook and loop fastener 223 and the rough sandpaper 224 on the conveyor belt 37. This example is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 13 The two ends of the second fixed shaft 35 are provided with push rod devices 6. The push rod device 6 includes a first piston chamber 61 fixedly connected to both ends of the second fixed shaft 35. A T-shaped piston plate 62 is slidably connected in the first piston chamber 61. A piston spring 63 is fixedly connected to the bottom of the T-shaped piston plate 62. The other end of the piston spring 63 is fixedly connected to the inside of the first piston chamber 61. The T-shaped piston plate 62 passes through the first piston chamber 61. An arc plate 64 is fixedly connected to one end of the T-shaped piston plate 62. The arc plate 64 is set on the outer wall of the second transmission shaft 36.

[0059] The bottom of piston chamber 61 is connected to piston chamber 66 via hose 65. A transmission piston plate 67 is slidably connected inside piston chamber 66. The bottom of transmission piston plate 67 is fixedly connected to the upper surface of sliding plate 43.

[0060] The second piston chambers 66 on both sides are fixedly connected by positioning rods 68. The second piston chamber 66 on the side closer to the base plate 1 is fixedly connected to a second fixing rod 69, and the other end of the second fixing rod 69 is fixedly connected to the base plate 1.

[0061] To ensure the bonding strength between the new rough sandpaper 224 and the hook and loop fastener 223, the lifting height of the conveyor belt 37 is further increased by the push rod device 6 during the lifting process, thereby ensuring the contact strength between the rough sandpaper 224 and the hook and loop fastener 223.

[0062] The second piston chambers 66, located on both sides below the conveyor belt 37, are connected by positioning rods 68 and fixed to the base plate 1 by second fixing rods 69. As the sliding plate 43 slides upward, it drives the transmission piston plate 67, fixedly connected to the sliding plate 43, to slide upward synchronously. The sliding of the transmission piston plate 67 compresses the hydraulic oil in the second piston chamber 66, and through the transmission of the hose 65, drives the T-shaped piston plate 62 in the first piston chamber 61 to slide upward, thereby driving the arc-shaped plate 64 installed at one end of the T-shaped piston plate 62 to slide upward. Because the first piston chamber... Piston chamber 61 is installed on both sides of the second fixed shaft 35. Piston chamber 61 rotates synchronously with the rotation of the second fixed shaft 35. Therefore, the arc plate 64 slides upward relative to the second fixed shaft 35. The arc plate 64 is located between the second drive shaft 36 and the conveyor belt 37. Therefore, by sliding the arc plate 64 upward, one end of the conveyor belt 37 will be further lifted, thereby ensuring the contact force between the rough sandpaper 224 and the hook Velcro 223 on the conveyor belt 37, preventing the rough sandpaper 224 from falling off during polishing, and improving the stability of the device.

[0063] Driven by the sliding plate 43, the first piston chamber 61 will move relative to the second piston chamber 66. If the two are connected by a rigid pipe, the first piston chamber 61 will be stuck and unable to move. Therefore, in order to prevent this from happening, the two are connected by a rubber hose 65. The piston spring 63 is designed to drive the T-shaped piston plate 62 to reset.

[0064] Example 3 aims to address the problem of excessive debris generated during polishing, which, if left on the workpiece 23, can negatively impact the polishing effect. This example is an explanation based on Example 2. For details, please refer to [link to example]. Figures 1 to 13 A cooling device 7 is provided above the workpiece 23. The cooling device 7 includes a water tank 71 fixedly connected to the base plate 1. A sliding plate 72 is slidably connected inside the water tank 71. A lifting rod 73 is fixedly connected to the bottom of the sliding plate 72. The lifting rod 73 passes through the water tank 71. The bottom end of the lifting rod 73 is fixedly connected to the upper surface of the right-angled trapezoidal rod 48. A water tank spring 74 is fixedly connected to the lower surface of the sliding plate 72. The other end of the water tank spring 74 is fixedly connected inside the water tank 71. A water outlet pipe 75 and a water inlet pipe 76 are connected inside the water tank 71. The output end of the water outlet pipe 75 is located above the workpiece 23.

[0065] In the polishing process, a common method for cleaning debris is to use water to rinse away the debris remaining on the surface of the workpiece 23. However, if the water pressure is low, it cannot completely clean the debris from the surface. If high-pressure water is used to continuously rinse the workpiece 23, it may cause the workpiece 23 to detach from the mounting shaft 24, affecting the polishing process. Therefore, by designing the cooling device 7, it is possible to prevent the high-pressure water from washing the workpiece 23 off the mounting shaft 24 while cleaning debris.

[0066] Under normal conditions, water is filled above the water tank 71 through the inlet pipe 76. After the water tank 71 is full, it flows out through the outlet pipe 75. At this time, the water flow intensity is low. When the sliding plate 43 rises, the lifting rod 73 located on the upper surface of the right-angled trapezoidal rod 48 slides upward simultaneously, thereby driving the sliding plate 72 to squeeze the space inside the water tank 71. Since the space inside the water tank 71 is reduced, and one-way valves are installed in the outlet pipe 75 and the inlet pipe 76, the water in the water tank 71 will quickly spray out through the outlet pipe 75, which will have a pressurizing effect. The pressurized water flow will wash away the debris that is difficult to wash away from the workpiece 23. At the same time, the intermittent design ensures that the workpiece 23 is not subjected to water flow for a long time. Through this design, the surface debris of the workpiece 23 is cleaned while ensuring the stability of the workpiece 23. At the same time, rinsing the workpiece 23 with water flow can also reduce the heat generated by the friction between the workpiece 23 and the rough sandpaper 224, protecting the integrity of the workpiece 23.
