Description

Technical Field

[0001] The present application relates to the field of resin product production, and in particular to a device for surface finishing of resin products. Background Art

[0002] Resin products are widely used in many fields such as electronics and electrical, automobile manufacturing, architectural decoration, art creation and daily necessities due to their excellent corrosion resistance, good insulation performance, easy processing and strong plasticity, etc., meeting the needs of different industries for aesthetics, durability and functionality.

[0003] After the resin product is cured and shaped, the surface or corners of the resin product may be uneven or have burrs due to the material's own characteristics and processing methods. In order to improve the appearance quality of the resin product, the resin product needs to be processed secondary. There is a kind of grinding equipment that controls the clamping table to clamp the resin product through a controller. The operator controls the clamping table to move toward the grinding wheel, and the grinding wheel is used to grind the resin product to make the surface of the resin product relatively flat, which is convenient for subsequent processing steps.

[0004] However, in actual applications, due to the diverse sizes of workpieces, after the clamping table clamps the workpiece, the workpiece will be subjected to a large force at the moment the clamped workpiece contacts the grinding wheel. If the force exerted by the clamping table on the workpiece is less than the force exerted by the grinding wheel on the workpiece, the workpiece will fall off along the clamping table. Under the influence of inertia, the workpiece may fly out along the clamping table, posing a safety hazard. Utility Model Content

[0005] In order to improve the safety of resin products during surface finishing, the present application provides a resin product surface finishing device.

[0006] The present application provides a resin product surface finishing device that adopts the following technical solution:

[0007] A resin product surface finishing device includes a frame, a carrying platform, a drive assembly and a grinding wheel machine, wherein the grinding wheel machine is arranged on the frame, the carrying platform is slidably arranged on the frame, the drive assembly is arranged on the frame, and the drive assembly is used to drive the carrying platform to move closer to or away from the grinding wheel machine. A fixing fixture is detachably provided on the carrying platform, and the fixing fixture is recessed along the thickness direction to form a cavity that is adapted to the external contour of the resin product. The cavity is used to fix the resin product, and a negative pressure pipeline is opened in the cavity, and the negative pressure pipeline is externally connected to a vacuum generator.

[0008] By adopting the above technical solution, the driving component drives the supporting platform along the frame to move closer to or away from the grinding wheel machine. Since the supporting platform is detachably provided with a fixing fixture, a cavity is provided on the fixing fixture. The placement position of the resin product when it is placed on the fixing fixture is limited by the cavity, and a negative pressure pipeline is provided in the cavity. When the resin product is placed in the cavity, the negative pressure pipeline starts to extract the air between the cavity and the resin product, so that the cavity and the resin product are in a negative pressure state. The air pressure difference is used to stably fix the resin product in the cavity, thereby reducing the probability of the resin product flying along the frame when the grinding wheel machine is processing the resin product.

[0009] Preferably, a silicone cushion is provided in the cavity.

[0010] By adopting the above technical solution, since the silicone pad is soft and easy to deform, when the vacuum generator starts working, the resin product located in the cavity is affected by the air pressure and moves toward the bottom of the cavity, thereby driving the silicone pad to deform. The silicone pad fills the gap between the resin product and the cavity, thereby improving the stability of the resin product when placed in the cavity.

[0011] Preferably, a clamping area is provided on the supporting platform, and the fixing fixture is clamped in the clamping area.

[0012] By adopting the above technical solution, the fixing jig is clamped through the clamping area, so that the fixing jig can be disassembled along the bearing platform or fixed on the bearing platform, which is easy to operate.

[0013] Preferably, a micro-motion cylinder is provided on the supporting platform, and a piston rod of the micro-motion cylinder movably passes through the clamping area and the fixing fixture and extends into the cavity.

[0014] By adopting the above technical solution, the micro-motion cylinder provides additional clamping force for the resin product when it is placed in the cavity, thereby further enhancing the stability of the resin product when it is placed in the cavity.

[0015] Preferably, a distance detection sensor is provided on the supporting platform, a detection end of the distance detection sensor faces the grinding machine, and a controller is electrically connected to the distance detection sensor and the driving assembly.

[0016] By adopting the above technical solution, the distance between the fixed jig and the grinding wheel machine is detected by a distance detection sensor, and the control is electrically connected to the distance detection sensor and the drive component, thereby reducing the probability of the fixed jig directly contacting the grinding wheel machine due to the drive component driving the carrier platform to carry the fixed jig to the grinding wheel machine for an excessive distance, thereby causing damage to the fixed jig and / or the grinding wheel machine, which is conducive to improving the overall safety performance during work.

[0017] Preferably, a flushing pipeline is provided on the frame, and the water outlet of the flushing pipeline faces the fixing fixture.

[0018] By adopting the above technical solution, when the grinding wheel machine processes the resin product on the fixed fixture, the grinding wheel machine and the resin product are cooled through the flushing pipeline, thereby reducing the probability of resin product debris adhering to the grinding wheel machine. At the same time, the resin product debris ground off by the grinding wheel machine is flushed through the flushing pipeline, thereby reducing the amount of flying debris.

[0019] Preferably, the grinding machine is provided with an isolation cover along the rotation direction.

[0020] By adopting the above technical solution, since an isolation cover is provided on the grinding wheel machine, when the resin product on the fixed fixture falls off along the fixed fixture, the resin product will fly out along the tangential direction of the rotation direction of the grinding wheel machine. The resin product will be blocked by the isolation cover, which is beneficial to improving the overall safety performance.

[0021] Preferably, a magnetic lock is provided in the clamping area, and when the fixing fixture is provided in the clamping area, the bottom of the fixing fixture abuts against the surface of the magnetic lock.

[0022] By adopting the above technical solution, when the fixing jig is set in the clamping area, the fixing jig is fixed to the supporting platform by the magnetic lock, thereby improving the stability of the fixing jig when it is set on the supporting platform.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the resin product is placed in the cavity, the negative pressure pipeline begins to extract the air between the cavity and the resin product, thereby creating a negative pressure state between the cavity and the resin product. The pressure difference is used to stably fix the resin product in the cavity, reducing the probability of the resin product flying along the frame when the grinding wheel machine is processing the resin product.

[0025] 2. The fixed fixture is clamped through the clamping area, so that the fixed fixture can be removed along the load-bearing platform or fixed on the load-bearing platform, which is easy to operate;

[0026] 3. Use a magnetic lock to secure the fixture to the platform to improve stability when the fixture is placed on the platform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a resin product surface finishing device. Figure 1 and Figure 2 A resin product surface finishing device includes a frame 1, a carrying platform 2, a driving assembly 3 and a grinding wheel machine 4. The grinding wheel machine 4 is arranged on the frame 1, the carrying platform 2 is slidably arranged on the frame 1, and the driving assembly 3 is arranged on the frame 1. The driving assembly 3 is used to drive the carrying platform 2 to move closer to or away from the grinding wheel machine 4. A fixing fixture 5 is detachably provided on the carrying platform 2. The fixing fixture 5 is recessed along the thickness direction to form a cavity 6 that is adapted to the external contour of the resin product. The cavity 6 is used to fix the resin product. A negative pressure pipeline 7 is opened in the cavity 6, and the negative pressure pipeline 7 is externally connected to a vacuum generator.

[0033] Specifically, the rack 1 is provided with a slide rail 15 along the width direction. At the same time, a slider 16 is installed on the surface of the supporting platform 2 facing the rack 1. The slide rail 15 and the slider 16 slide together, so that the supporting platform 2 can slide smoothly along the rack 1, thereby improving the stability of the supporting platform 2 when sliding along the rack 1.

[0034] At the same time, the driving assembly 3 includes a driving screw 31 and a servo motor 32. The servo motor 32 is installed on the frame 1. The output shaft of the servo motor 32 is set in the same direction as the slide rail 15. The driving screw 31 is coaxially fixed with the output shaft of the servo motor 32, and the driving screw 31 is threadedly engaged with the supporting platform 2.

[0035] Therefore, when the output shaft of the servo motor 32 rotates, the driving screw 31 rotates synchronously with the output shaft of the servo motor 32 , thereby driving the supporting platform 2 along the frame 1 to move closer to or away from the grinding machine 4 .

[0036] Through the above process, the servo motor 32 and the driving screw 31 cooperate to drive the supporting platform 2 to carry the fixed fixture 5 on which the resin product is placed close to or away from the grinding wheel 4, thereby completing the purpose of grinding the surface of the resin product. Since a negative pressure pipeline 7 is opened in the cavity 6 of the fixed fixture 5, the vacuum generator is used to provide power for the negative pressure pipeline 7 to extract the air between the cavity 6 and the resin product, so that the cavity 6 and the resin product are in a negative pressure state, thereby improving the stability of the resin product when placed in the cavity 6.

[0037] It should be noted here that the grinding machine 4 includes a grinding wheel and a drive motor. The grinding wheel is coaxially fixed with the output shaft of the drive motor, so that the grinding wheel can rotate synchronously with the output shaft of the drive motor, providing power for the surface processing of resin products, and is a conventional grinding component.

[0038] At the same time, the vacuum generator forms a low-pressure area inside through the flow of compressed air, thereby generating negative pressure, thereby realizing functions such as adsorption and transportation of target objects or systems. It is a conventional pneumatic suction component, and its specific composition and working principle are not described here.

[0039] Reference Figure 1 and Figure 2 A clamping area 10 is provided on the carrying platform 2 , and the fixing fixture 5 is clamped in the clamping area 10 .

[0040] Specifically, the contour of the clamping area 10 is adapted to the contour of the fixing jig 5, and the tolerance matching relationship between the clamping area 10 and the fixing jig 5 is a clearance fit, so that the fixing jig 5 can be smoothly taken out along the clamping area 10, or the fixing jig 5 can be placed in the clamping area 10, thereby improving the stability of the fixing jig 5 when installed on the supporting platform 2.

[0041] Correspondingly, a magnetic lock is provided within the engaging area 10. When the fixture 5 is positioned within the engaging area 10, the bottom of the fixture 5 abuts against the surface of the magnetic lock. Because the tolerances between the fixture 5 and the engaging area 10 are clearance-matched, a gap exists between the fixture 5 and the engaging area 10. Therefore, the magnetic force provided by the magnetic lock stabilizes the fixture 5 and the engaging area 10, minimizing any looseness of the fixture 5 when installed within the engaging area 10.

[0042] Reference Figure 2 and Figure 3 A silicone cushion 8 is provided in the cavity 6. Because the silicone cushion 8 is soft and easy to deform, when the vacuum generator starts working, the resin product in the cavity 6 moves toward the bottom of the cavity 6 under the influence of air pressure, thereby driving the silicone cushion 8 to deform. The silicone cushion 8 fills the gap between the resin product and the cavity 6, thereby improving the stability of the resin product when placed in the cavity 6.

[0043] Reference Figure 2 and Figure 3 A micro-motion cylinder 11 is provided on the supporting platform 2 , and the piston rod of the micro-motion cylinder 11 movably passes through the clamping area 10 and the fixing fixture 5 , and extends into the cavity 6 .

[0044] Specifically, two micro-cylinders 11 are provided, and the two micro-cylinders 11 are respectively installed on the two side walls of the clamping area 10 along the width direction, and the piston rods of the two micro-cylinders 11 are arranged opposite to each other. When the resin product is placed in the cavity 6, the micro-cylinder 11 provides additional clamping force for the resin product when it is placed in the cavity 6, further enhancing the stability of the resin product when it is placed in the cavity 6.

[0045] Reference Figure 1 and Figure 2 A flushing pipeline 13 is provided on the frame 1 , and the water outlet of the flushing pipeline 13 faces the fixed fixture 5 .

[0046] Specifically, the water inlet of the flushing pipe 13 can be connected to a water pump, and the coolant is pumped into the flushing pipe 13 by the water pump. When the grinding wheel machine 4 is grinding the resin product, the grinding wheel machine 4 and the resin product are cooled through the flushing pipe 13, thereby reducing the probability of the resin product debris adhering to the grinding wheel machine 4. At the same time, the resin product debris ground off by the grinding wheel machine 4 is flushed through the flushing pipe 13, thereby reducing the amount of flying debris.

[0047] At the same time, an isolation cover 14 is provided in the rotation direction of the grinding wheel machine 4. The isolation cover 14 is formed by welding of metal plates so that it has a certain impact resistance. Because the isolation cover 14 is provided on the grinding wheel machine 4, when the resin product on the fixed fixture 5 falls off along the fixed fixture 5, the resin product will fly out along the tangential direction of the rotation direction of the grinding wheel machine 4. The resin product is blocked by the isolation cover 14, which is conducive to improving the overall safety performance.

[0048] Reference Figure 1 and Figure 2 A distance detection sensor 12 is provided on the supporting platform 2 , the detection end of the distance detection sensor 12 faces the grinding wheel machine 4 , and the controller is electrically connected to the distance detection sensor 12 and the driving component 3 .

[0049] Specifically, the controller described here is an existing PLC (Programmable Logic Controller) control system of the grinding equipment, which has a human-computer interaction interface. Its specific composition and working principle are not described in detail here.

[0050] At the same time, the controller controls the working state of the servo motor 32, so that the output of the servo motor 32 drives the driving screw 31 to rotate, so that the supporting platform 2 carries the fixed jig 5 with the resin product placed thereon to move toward the grinding wheel 4, and the distance detection sensor 12 detects the distance between the grinding wheel 4 and the resin product placed in the cavity 6, and transmits it to the controller in real time. When the distance detection sensor 12 detects that the distance between the fixed jig 5 and the grinding wheel 4 meets the distance set by the operator, the controller controls the servo motor 32 to stop rotating for 2s to 2.5s (international unit, seconds) to complete the grinding of the resin product. Then the controller controls the output shaft of the servo motor 32 to rotate in the opposite direction, so that the supporting plate carrying the fixed jig 5 is away from the grinding wheel 4, so that the operator can remove the processed resin product along the cavity 6.

[0051] Therefore, through the coordinated cooperation between the distance detection sensor 12, the controller and the servo motor 32, the probability of the fixed fixture 5 and / or the grinding wheel 4 being damaged due to the output shaft of the servo motor 32 driving the driving screw 31 to rotate too much, resulting in an excessive stroke limit, causing direct contact between the fixed fixture 5 and the grinding wheel 4, and improving the overall safety performance.

[0052] The implementation principle of a resin product surface finishing device in an embodiment of the present application is as follows: the output shaft of the servo motor 32 drives the driving screw 31 to rotate along the frame 1, so that the supporting platform 2 carries the fixed fixture 5 and moves along the frame 1 towards or away from the grinding wheel machine 4. Through the cooperation of the vacuum generator and the negative pressure pipeline 7, the air between the cavity 6 and the resin product is extracted, and the resin product is stably fixed in the cavity 6 by using the negative pressure. At the same time, the micro-motion cylinder 11 provides auxiliary supporting force for the resin product, further improving the stability of the resin product when placed in the cavity 6. The coordinated cooperation between the distance detection sensor 12, the controller and the servo motor 32 greatly reduces the probability of damage to the fixed fixture 5 and / or the grinding wheel machine 4 due to the exceeding of the stroke limit of the supporting seat moving toward the grinding wheel machine 4.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
