Description

Technical Field

[0001] This invention relates to the field of precision machining technology for injection molded socket parts, and specifically discloses a device for deburring the shell of a wall socket. Background Technology

[0002] Wall panel socket housings on the market are usually manufactured using injection molding. However, during the injection molding process, factors such as excessive pressure and incomplete mold closure often result in burrs and flash at the ends of the molded workpiece. Therefore, subsequent finishing is required to ensure product quality.

[0003] Existing deburring equipment for wall panel socket housings can only process one at a time, resulting in low processing efficiency and failing to meet the continuous molding capacity of multiple injection molding machines in a factory. For example, utility model patent application number 202221311005.2 discloses a deburring device for socket production, including a worktable, a movable plate movably connected to the top of the worktable, a slider fixedly connected to the bottom of the movable plate, a lifting plate movably connected to the front of the movable plate, a handle fixedly connected to one side of the lifting plate, a movable groove on the front of the movable plate, a double-headed telescopic rod fixedly connected to one side of the lifting plate, a clamping plate fixedly connected to one end of the double-headed telescopic rod, a protective shell fixedly connected to one side of the worktable, a motor fixedly connected to the inner wall of the protective shell, a rotating shaft fixedly connected to the output shaft of the motor via a coupling, and a grinding block fixedly connected to the outer wall of the rotating shaft. The deburring equipment disclosed in this patent, when grinding and deburring wall panel socket housings, not only can only clamp one wall panel socket housing at a time before grinding and deburring, limiting its processing efficiency, but also suffers from unstable clamping when using a clamp composed of a double-headed telescopic rod and clamping plates due to the low overall thickness of the wall panel socket housing, leading to situations where the clamping plates come into contact with the grinding blocks during grinding. Furthermore, the inner ends of the socket holes on the wall panel socket housing have pull burrs, which are difficult to remove by grinding, requiring secondary manual processing and reducing processing efficiency. Therefore, to address the above-mentioned shortcomings of existing edge deburring equipment for socket production, this application proposes a wall socket housing deburring device specially designed for wall socket housings, enabling batch deburring of wall socket housings. Summary of the Invention

[0004] The present invention aims to provide a burr removal device for wall socket housings, in order to solve the technical problems of low operating efficiency, unstable workpiece clamping, and difficulty in grinding and removing burrs pulled from the inner end of the socket holes in existing socket production deburring equipment.

[0005] This invention is achieved through the following technical solution:

[0006] A wall socket housing burr removal device includes a conveying unit, a gripping and switching unit, and a polishing unit. The conveying unit is provided with an adjustment and positioning mechanism that arranges a row of wall socket housings at predetermined intervals. The gripping and switching unit is located directly above the conveying unit, and the polishing unit is aligned and located on one side of the conveying unit.

[0007] The gripping and switching unit includes two uprights fixed to the upper end of the conveying unit. A hollow drum is rotatably arranged between the two uprights, and a power component for driving the hollow drum to rotate is provided on the uprights. Multiple stepped slots are evenly opened on the outer side of the hollow drum. A strip plate is fixed in the hollow drum inside each stepped slot. An outer strip plate is provided at the outer end of each stepped slot. The outer strip plate has a plug hole that is aligned with the housing of each wall socket after adjustment and positioning. An inner strip plate is connected to the inner side of the outer strip plate through a first spring. The inner strip plate has multiple sets of plugs that pass through the plug hole and interact with the plug hole on the housing of the wall socket. The inner strip plate and the strip plate are movably connected by a guide rod and a second spring.

[0008] The hollow drum has an inner column concentrically mounted inside and fixed to the support frame. Three electromagnets are mounted on the outer surface of the inner column. One electromagnet is vertically downward, and the other two electromagnets are facing and away from the grinding unit, respectively. The inner strip is equipped with a permanent magnet that interacts with the electromagnets.

[0009] The wall socket housing burr removal device disclosed in this invention uses a conveying unit to transport multiple wall socket housings to a set position at one time, and then activates an adjustment and positioning mechanism to arrange the multiple wall socket housings at set intervals and precisely align them with each set of plugs.

[0010] Next, the hollow drum, driven by a power unit, rotates to align a row of prongs with the wall socket housing after they have been arranged. Once aligned, current is passed through the corresponding electromagnets, generating a repulsive force against the permanent magnets. Under this repulsive force, the bottom set of inner and outer strips moves vertically downwards, allowing the prongs to be inserted into the sockets on the wall socket housing. An interference fit ensures a stable connection between the wall socket housing and the prongs, and the outer surface of the wall socket housing is in contact with the outer strip.

[0011] After the wall socket housing is picked up, the next batch of wall socket housings is loaded and positioned. Then, the picking and switching unit rotates 90° so that the open end of the picked wall socket housing faces the grinding unit. Current is then passed through the corresponding electromagnet to generate a repulsive force against the permanent magnet, which pushes the open end of a row of wall socket housings to abut against the sanding belt in the grinding unit. The sanding belt is used to grind and remove the burrs on the open end of the wall socket housing.

[0012] After the burrs on the wall socket housing are removed by grinding, the gripping and switching unit is rotated 180°. Then, a reverse current is passed through the corresponding electromagnet to generate a magnetic attraction force on the permanent magnet, thereby moving the inner strip, outer strip, and the gripped wall socket housing toward the interior of the hollow drum. When it reaches the stepped opening, the outer strip is restricted and cannot move further, while the inner strip continues to move inward. During the inward movement of the inner strip, the plug is pulled out of the socket hole of the wall socket housing. Then, the polished wall socket housing automatically falls, thus completing the entire grinding and deburring process.

[0013] As a further provision of the above solution, the conveying unit includes a conveyor base, with a belt roller at each end of the conveyor base, a conveyor belt between the two belt rollers, a guide plate on one side of the front end of the conveyor base, and a limit baffle on the same side of the rear end of the conveyor base. The above is one specific design scheme for the conveying unit, which uses a conveyor belt to transport the wall socket housing, guides the transported housing with a guide plate, and uses a limit baffle to position the housing at a designated location.

[0014] As a further provision of the above scheme, the adjustment and positioning mechanism includes a row of first cylinders evenly spaced on the side of the conveyor seat. Each cylinder's telescopic end is connected to a triangular guide block. A second cylinder is located on the side of the conveyor seat opposite the first cylinders, and the telescopic end of the second cylinder is connected to a strip-shaped push plate. This is one specific design scheme for the adjustment and positioning mechanism. During operation, the second cylinder first pushes the strip-shaped push plate towards the wall socket housing, thereby adjusting its longitudinal alignment. Then, the first cylinders are activated one by one, and under the action of the triangular guide blocks, the multiple wall socket housings that were originally tightly pressed together are evenly spaced, thus enabling precise alignment with each set of plug components.

[0015] As a further provision of the above scheme, bearings are provided at the upper ends of both uprights, and hollow end shafts connected to the bearings are concentrically arranged on both ends of the hollow drum. The power assembly is connected to one of the hollow end shafts. The above is one of the specific installation methods between the hollow drum and the uprights. The hollow end shafts are driven by the power assembly, thereby driving the hollow drum to rotate according to the design requirements.

[0016] As a further feature of the above scheme, the two ends of the inner column are concentrically connected with end rods that pass through the hollow end shaft. One end rod is fixedly connected to the upright plate on the frame, and the other end rod is connected to a bearing inside the hollow end shaft. This is one specific installation method for the inner column. Through the extension design of the two end rods, one end is fixedly connected to the frame, while the other end is rotatably set relative to the hollow drum, thus not affecting the rotation adjustment of the hollow drum.

[0017] As a further provision of the above solution, two guide rods are provided on the inner strip plate, respectively located at both ends of the inner strip plate. Guide holes that interact with the guide rods are opened at both ends of the strip plate. The second spring is sleeved on the guide rods, and both ends of the second spring are connected to the strip plate and the inner strip plate, respectively. This is one specific connection scheme between the inner strip plate and the strip plate. The design of the two guide rods allows the inner strip plate to move stably radially inward or outward when subjected to magnetic force.

[0018] As a further feature of the above scheme, arc-shaped blocks are concentrically arranged on both sides of the upper end of the inner column. Copper sheets connected to external circuits are arranged on the outer circular surface of the arc-shaped blocks. Carbon brush blocks that interact with the corresponding copper sheets are arranged at the ends of the two guide rods. Each set of the plug components is connected to the carbon brush blocks through built-in wires. The plug components are made of resistive material or have built-in heating wires.

[0019] The above is a further improved design of the present invention. After the grinding unit completes the grinding of the burrs on the open end of the wall socket housing, when the wall socket housing rotates upward with the hollow drum, the carbon brush block will come into contact with the copper sheet, thereby realizing the conduction of the circuit. At this time, the plug will melt the pull burrs on the inner end of the socket that it is plugged into through a brief heating, thereby achieving the effect of melting and removing the pull burrs on the inner end of the socket, solving the problem that the pull burrs on the inner end of the socket cannot be removed by grinding.

[0020] As a further provision of the above solution, the polishing unit includes a vertically fixed belt abrasive drive box with an opening facing the gripping and switching unit. The belt abrasive drive box contains belt abrasive components arranged side-by-side, aligned with each insertion hole. This is one specific design scheme for the polishing unit, utilizing each belt abrasive component to independently polish the open end of the pushed-in wall socket housing, thereby effectively removing burrs from its port.

[0021] As a further improvement to the above solution, a water tank is also included, on which a water pump is installed. A water supply pipe is connected to the water pump, and a row of spray nozzles is installed on the water supply pipe. Each spray nozzle passes through the back of the belt sander and is aligned with each belt sanding assembly. A water storage tank is located at the lower end of the belt sander, and a drain pipe is connected to the bottom of the water storage tank. This is a further improved design of the present invention. During the sanding process of the belt sander assembly on the open end of the wall socket housing, cleaning fluid can be sprayed online onto the back of the sander belt through the spray nozzles. The cleaning fluid effectively washes away the dust adhering to the sander belt during sanding, ensuring the subsequent sanding effect. Secondly, it cools the sander belt, preventing deformation of the wall socket housing due to frictional heat generated during prolonged sanding, thus ensuring product quality.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The wall socket housing burr removal device disclosed in this invention utilizes a special design of the gripping and switching unit. After multiple wall socket housings are arranged and positioned, the device can quickly and stably grip multiple wall socket housings at once by using the interference fit between the plug and the socket hole of the wall socket housing. Then, by rotating and switching, the gripped wall socket housings are oriented towards the sanding belt grinding component, which then completes the sanding and deburring of multiple wall socket housings in one go, effectively improving the efficiency of sanding and deburring. At the same time, during the sanding process, the inner and outer strips are connected by a first spring, which allows the open end of the wall socket housing to adaptively adjust during the pressing and contact with the sanding belt, avoiding quality problems caused by incomplete or excessive sanding of the burrs at the open end of the wall socket housing.

[0024] This invention further features a special design for the plug component, enabling it to heat up when energized. Combined with the rotation switching of the hollow drum, the carbon brush block, and the copper sheet, the plug component is able to briefly heat up during the process of rotating and switching to the unloading station after the burrs at the opening end of the wall socket housing have been polished. The high temperature of the plug component is then used to quickly melt and remove the burrs at the inner end of the socket hole in the wall socket housing. Combined with the previous port polishing process, all the burrs on the entire wall socket housing can be completely removed.

[0025] The grinding device in this invention further incorporates a spray rinsing process, which allows the sanding belt to be cleaned simultaneously on the back by the rinsing liquid while it is grinding and deburring the open end of the wall socket housing. This ensures continuous grinding effect of the sanding belt and enables real-time cooling of the sanding belt, preventing deformation of the wall socket housing caused by frictional heat generated during long-term grinding operation, and further ensuring the product quality after deburring.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-11 This application will be described in detail with reference to the embodiments. Example 1

[0040] Example 1 discloses a device for deburring wall socket housings, see attached drawing. Figure 1 and attached Figure 2 The main body of the device includes a conveying unit 100, a gripping and switching unit 200, and a grinding processing unit 300. The conveying unit 100 includes a conveying seat 101, with a belt roller at each of the front and rear ends of the conveying seat 101. A conveyor belt 102 for conveying the wall socket housing 400 is arranged between the two belt rollers. A guide plate 103 is also provided on one side of the front end of the conveying seat 101, and a limit baffle 104 is provided on the same side of the rear end of the conveying seat 101. This allows the injection-molded wall socket housings to be conveyed one by one to the rear end of the conveyor belt 102 under the action of the conveyor belt 102, the guide plate 103, and the limit baffle 104, and to be arranged in rows tightly together.

[0041] Reference Appendix Figure 3 To ensure that the multiple wall socket housings 400 on the conveyor belt 102 are arranged at predetermined intervals before being gripped, an adjustment and positioning mechanism 500 is also provided on the conveyor seat 101. Specifically, the adjustment and positioning mechanism 500 includes a row of first cylinders 501 evenly spaced on the side of the conveyor seat 101 near the guide plate 103, with a triangular guide block 502 connected to the telescopic end of each cylinder 501. A second cylinder 503 is provided on the side of the conveyor seat 101 opposite the first cylinders 501, and a strip-shaped pusher plate 504 parallel to the conveying direction is connected to the telescopic end of the second cylinder 503. After multiple wall socket housings 400 are placed side by side on the conveyor belt 102, the second cylinder 503 is first activated to push the strip pusher 504 toward the multiple wall socket housings 400 to align them longitudinally. Then, the first cylinder 501 is controlled to extend one by one, so that each triangular guide block 502 is inserted into the contact area between two adjacent wall socket housings 400, thereby separating the multiple wall socket housings 400 at equal intervals in the lateral direction, thus completing the precise positioning of the front wall socket housing 400.

[0042] Reference Appendix Figures 4-10The gripping and switching unit 200 includes two uprights 201 fixed to the upper ends of the conveyor seat 101. Each upright 201 has a bearing at its upper end, and a hollow drum 202 is concentrically positioned between the two bearings. Both ends of the hollow drum 202 are concentrically connected to hollow end shafts 203 that are connected to the bearings. A power assembly 204 for driving the hollow drum 202 to rotate is mounted on one of the uprights 201. Specifically, the power assembly 204 includes a motor fixed to the upright 201, and a pair of meshing gears are mounted on the motor shaft and the hollow end shaft 203. This allows the hollow drum 202 to rotate stably at a set speed and angle under the power input from the motor and the meshing transmission of the gears.

[0043] Multiple stepped slots 205 are arranged in a circular array on the outer surface of the hollow drum 202, with the number of stepped slots 205 ranging from 4 to 8. A strip plate 206 is fixedly installed inside the hollow drum 202 on the inner side of each stepped slot 205. A circular hole 2061 is formed in the center of the strip plate 206, and guide holes are formed at both ends. An outer strip plate 207 is provided at the outer end of each stepped slot 205 to mate with it. The outer strip plate 207 has insertion holes 2071 aligned with the pin holes on each wall socket housing 400 after adjustment and positioning, and these insertion holes 2071 are aligned with the pin holes on the wall socket housing 400 one by one. An inner strip plate 209, slightly smaller than the stepped slots 205, is connected to the inner side of the outer strip plate 207 via a first spring 208. A pin member 210, aligned with each set of pin holes, is provided on the outer side of the inner strip plate 209. The plug 210 can pass smoothly through the socket 2071, and the size of the plug 210 is slightly larger than the size of the socket on the wall socket housing 400, so that after the plug 210 is inserted into the socket in the wall socket housing 400, the wall socket housing 400 can be stably connected to it.

[0044] Guide rods 211 that interact with guide holes on strip plate 206 are provided at both ends of the inner side of inner strip plate 209. Second springs 212 connected to strip plate 206 and inner strip plate 209 respectively are sleeved on guide rods 211. Then, permanent magnets 213 aligned with round holes 2061 are fixed on the inner side of inner strip plate 209.

[0045] An inner column 214 is concentrically arranged inside the hollow drum 202. Both ends of the inner column 214 have end rods 215 extending along the hollow end shaft 203. The outer end of one end rod 215 is fixedly connected to the upright plate 216 on the support frame 201, while the other end rod 215 is rotatably connected to a bearing inside the hollow end shaft 203. This ensures that the entire inner column 214 is fixed relative to the hollow drum 202, remaining stationary during the rotation of the hollow drum 202. Three electromagnets 220 are arranged on the outer surface of the inner column 214. One electromagnet 220 is vertically downwards, while the other two are horizontally oriented to the left and right. When the permanent magnet 213 on the inner strip 209 is aligned with the electromagnet 220 through the circular hole 2061, a corresponding magnetic field can be generated by passing current through the electromagnet 220, which in turn pushes the inner strip 209 and the outer strip 207 to move radially outward or inward under the action of magnetic force.

[0046] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 11 The sanding unit 300 includes a vertically mounted sanding belt drive box 301. The back of the sanding belt drive box 301 is fixedly mounted by several columns 302, and the sanding belt drive box 301 is positioned with an opening facing the side of the gripping and switching unit 200. Drive shafts 303 are rotatably mounted at both the upper and lower ends of the sanding belt drive box 301, and a sanding motor 304 is connected to the end of one of the drive shafts 303. Sanding belt rollers, aligned with each insertion hole 2071, are spaced apart on the upper and lower drive shafts 303, and sanding belts 305 are positioned between the multiple sets of vertically aligned sanding belt rollers for sanding the open ends of the wall socket housing 400.

[0047] The wall socket housing burr removal device disclosed in this embodiment 1, when processing wall socket housings 400 in batches, firstly, the conveying unit 100 conveys the wall socket housings 400 one by one to the rear end. Then, under the action of the conveyor belt 102, the guide plate 103 and the limiting baffle 104, they can be conveyed one by one to the rear end of the conveyor belt 102 and lined up tightly together.

[0048] Next, the adjustment and positioning mechanism 500 is activated. First, the second cylinder 503 pushes the strip pusher 504 toward multiple wall socket housings 400 to align them longitudinally. Then, the first cylinder 501 is extended one by one, so that each triangular guide block 502 is inserted into the fitting area between two adjacent wall socket housings 400, thereby separating the multiple wall socket housings 400 at equal intervals in the horizontal direction and precisely aligning them vertically with each set of pins 210 on the inner strip 209 at the bottom of the gripping and switching unit 200.

[0049] Subsequently, current is passed through the electromagnet 220 at the lower end to generate a magnetic force that repels the permanent magnet 213. Under the action of the magnetic force, the inner strip 209 and the outer strip 207 move vertically downward, so that the plug 210 passing through the plug hole 2071 can be inserted into the corresponding socket of the wall socket housing 400. Since the plug 210 and the socket are interference fit, the wall socket housing 400 and the plug 210 are stably connected, and the outer surface of the wall socket housing 400 is in close contact with the outer strip 207.

[0050] After the wall socket housing 400 is gripped, the power unit 204 starts operating, rotating the gripped wall socket housing 400 by 90° to face the grinding unit 300. Then, current is passed through the corresponding electromagnet 220, generating a magnetic force that repels the permanent magnet 213. This moves the inner strip 209, outer strip 207, and the row of gripped wall socket housings 400 toward the outer surface of the sanding belt 305 until the open end of the wall socket housing 400 is tightly pressed against the sanding belt 305. The sanding belt 305 then grinds the burrs at the ends of the wall socket housing 400. Simultaneously, because the inner strip 209 and outer strip 207 are connected by a first spring 208, they can adaptively adjust during the grinding process, preventing over-grinding of the open end of the wall socket housing 400 and affecting its quality.

[0051] Finally, after the grinding is completed, the power component 204 continues to drive the hollow drum 202 to rotate 180°, thereby rotating and adjusting the ground wall socket housing 400 to the opposite side. Then, a reverse current is passed into the electromagnet at this position, causing it to generate a magnetic attraction force with the permanent magnet 213. This moves the inner strip 209, the outer strip 207, and the row of wall socket housings 400 into the hollow drum 202. When they move to the stepped opening 205, the outer strip 207 will be restricted and unable to move further, while the inner strip 209 will continue to move inward. During the inward movement of the inner strip 209, the plug 210 is pulled out of the socket of the wall socket housing 400. Then, the row of wall socket housings 400 will automatically fall into the corresponding collection box or discharge conveyor (not shown in the figure), thus completing the entire grinding and deburring process. Example 2

[0052] Example 2 discloses a wall socket housing burr treatment device that is further optimized and improved based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.

[0053] Reference Appendix Figure 2 and attached Figure 11The system also includes a water tank 600, and the conveying unit 100, gripping and switching unit 200, and grinding unit 300 are all mounted on the upper surface of the water tank 600. A water pump 601 is installed on the water tank 600, and a water supply pipe 602 is connected to the water pump 601. A row of spray nozzles is installed on the water supply pipe 602, and each spray nozzle passes through the back of the sanding belt drive box 301 and is aligned with each sanding belt 305. At the same time, a water storage tank 306 is integrally formed at the lower end of the sanding belt drive box 301, and a drain pipe 307 is connected to the bottom of the water storage tank 306. In this embodiment 2, through the above design, during the process of sanding and deburring the wall socket housing 400 with the sanding belt 305, the water pump 601, water pipe 602 and spray nozzle can continuously spray cleaning fluid onto the sanding belt 305 from the back. On the one hand, it can wash away the dust attached to the sanding belt 305 to ensure the subsequent sanding effect. On the other hand, it can achieve real-time cooling of the sanding belt 305 to avoid deformation of the wall socket housing 400 due to frictional heat during the sanding process.

[0054] Reference Appendix Figures 6-9 Concentric arc-shaped blocks 217 are provided on the upper ends of both the front and rear sides of the inner column 214. Copper plates 218 connected to the positive and negative terminals of the external circuit are respectively provided on the outer circular surface of the two arc-shaped blocks 217, and the copper plates 218 are aligned with the guide rods 211 in the axial direction. At the same time, a carbon brush block 219 is connected to the outer end of each guide rod 211. Each set of pins 210 is connected to the carbon brush block 219 through built-in wires. The pins 210 are made of resistive material that heats up when energized, or made of thermally conductive material, and have built-in heating wires. In this embodiment 2, through the above design, after the burrs at the port of the wall socket housing 400 are removed by grinding and during the process of rotating towards the unloading station, the carbon brush block 219 at the end of the guide rod 211 contacts the copper sheet 218 to achieve circuit conduction, thereby causing the plug 210 to heat up briefly. Then, under the action of the heat of the plug 210, the pull-out burrs at the inner end of the socket on the wall socket housing 400 can be melted and removed, solving the deficiency that the pull-out burrs at the inner end of the socket cannot be removed by grinding.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
