Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and in particular to an automatic polishing device and method for quartz ring parts. Background Technology

[0002] After the ring-shaped quartz part is formed, in order to improve the smoothness of the quartz part surface, it is usually necessary to use grinding and polishing equipment to treat the surface of the quartz part. Existing technologies involved include:

[0003] 1. CN115890403B A quartz lens polishing device includes a base and an adjusting column vertically arranged on the base and rotatable about its own axis. Several telescopic rods are horizontally arranged along the circumferential direction at the same height on the side wall of the adjusting column. Each telescopic rod has a bearing ring on its output shaft. A horizontally rotatable driven ring is fitted inside the bearing ring. A lens driving assembly is provided on the outer wall of the bearing ring. The driving assembly drives the driven ring to rotate. The lens to be polished is fitted in the driven ring and rotates together. Two sets of extension arms are symmetrically arranged on both sides of the lens and can be displaced in opposite directions to facilitate simultaneous polishing of both sides of the lens surface, to ensure that both sides of the lens surface are subjected to the same pressure, and to maintain consistent smoothness of both sides of the lens surface.

[0004] 2. CN214351490U A polishing device for side polishing of quartz sheet surface, comprising a housing, wherein lower telescopic rods are respectively provided on both sides of the upper end face of the housing, and an upper telescopic rod is provided at the top of the two sets of lower telescopic rods, a rotating mechanism is provided at the lower middle end of the upper telescopic rod, a rotating disk is provided at the top of the rotating mechanism, the bottom end of the rotating disk is connected to a rotating disk base, the bottom end of the rotating disk base is connected to an upper polishing rotating shaft, an upper polishing base is provided at the bottom end of the upper polishing rotating shaft, and an upper side polishing disc is provided at the bottom end of the upper polishing base; capable of improving work efficiency;

[0005] However, since quartz is a brittle material at room temperature, and including but not limited to the aforementioned existing technologies, it typically does not have the function of heating quartz parts. Quartz is sensitive to temperature changes, and direct polishing will cause the polished area to generate high heat, while the unpolished area will have a lower temperature, resulting in a temperature gradient throughout the quartz material and causing thermal stress. At this time, microcracks are prone to occur at the polished area. These microcracks will expand during subsequent high-temperature use, causing the quartz parts to break and resulting in a low yield. Furthermore, including but not limited to the aforementioned existing technologies, when clamping disc-shaped quartz parts, the quartz parts are usually placed horizontally and fixed on the equipment. Therefore, the area of ​​the quartz part clamped by the fixture forms a processing blind zone. In order to achieve full grinding and polishing of the part surface, secondary or even multiple clamping operations must be performed, which prolongs the production cycle. In view of this, in-depth research was conducted on the above problems, which led to this case. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned problems by designing an automatic polishing device and method for quartz ring parts. This invention addresses the issue that existing quartz polishing equipment typically lacks the function of heating the quartz parts, leading to high heat generation at the polishing area and a temperature gradient across the quartz material, resulting in thermal stress. This causes microcracks to easily form at the polishing location, which can propagate during subsequent high-temperature use, leading to quartz part breakage and low yield. Furthermore, this invention includes, but is not limited to, the prior art where, when clamping disc-shaped quartz parts, they are typically placed horizontally on the equipment. This creates a processing blind zone where the clamped area requires secondary or even multiple clamping operations to achieve complete surface polishing, thus extending the production cycle.

[0012] Preferably, both the cylindrical heating end and the two disc heating ends include a lead screw module. The lead screw module is mounted on the V-type drive unit. A second electric push rod is mounted on the moving end of the lead screw module. An arbitrary stop bracket is mounted on the telescopic end of the second electric push rod.

[0013] Preferably, the arbitrary stop bracket includes a base plate, a gooseneck tube inserted into one side of the base plate, a frame plate fixedly fitted at one end of the gooseneck tube, a cover sleeve fitted over the base plate, the gooseneck tube and the frame plate, and a support rod fixedly passing through the cover sleeve and the frame plate.

[0014] Preferably, the V-type drive unit includes a base, a turntable mounted on the base, a V-shaped box mounted on the turntable, a geared motor mounted at the center of the side wall of the V-shaped box, the drive end of the geared motor penetrating through the outer side wall of the V-shaped box, a drive sprocket fixedly mounted on the drive end of the geared motor, a rotating shaft movably inserted into the V-shaped box via bearings, a driven sprocket fixedly mounted at one end of the rotating shaft, a tension sprocket mounted on the side wall of the V-shaped box, and the drive sprocket, driven sprocket, and tension sprocket interconnected by a chain.

[0015] Preferably, the pressing part includes a support, which is installed on the side wall of the V-shaped box and is arranged on the same side as the adjusting roller. A longitudinal rod is inserted into the support, a sleeve is fitted at one end of the longitudinal rod, a crossbar is inserted into the sleeve, and a roller is installed at one end of the crossbar. The roller is movably attached to the side wall of the annular product.

[0016] Preferably, the lamp holder includes a rectangular frame, the base is located at the center of the rectangular frame, and upright plates are provided on both sides of the rectangular frame. The lead screw module is longitudinally installed on the outer wall of the upright plates.

[0018] Preferably, V-shaped protective covers are installed on both sides of the V-shaped box.

[0019] An automatic polishing method for quartz ring parts includes the following steps;

[0020] Step 1: Place the quartz ring part to be polished horizontally on the two adjustable rollers of the vertical rotary machine, so that the cylindrical surface of the ring product is in contact with the support rollers on both sides, and the end face of the ring product is in contact with the fixed ring, that is, the adjustable rollers are in the first position.

[0021] Step 2: Start the positioner to make the first electric push rod push the push ring to move, so that the push ring fits against the other end face of the ring product, that is, the adjustment roller is in the second position;

[0024] Step 5: After the cylindrical surface and one side end face of the ring product are polished, the preheating lamp is activated, moving the preheating lamp away from the ring product. The turntable of the V-type drive unit rotates 180 degrees, turning the other side end face of the ring product toward the polishing robot. The polishing end continues to polish the ring product.

[0025] Step 6: After polishing is completed, the base, robotic arm, polishing end, preheating lamp and V-type drive unit stop working, the clamping part is released, and the positioner of the pitch roller is retracted to the first position. The polished ring product is then removed.

[0026] The automatic polishing device and method for quartz ring parts manufactured using the technical solution of this invention involves placing the ring product on the support rollers of the adjustable rollers on both sides of the V-type drive unit. The adjustment device provides stable support for the ring product with its axis in a horizontal state. This method is suitable for thinner ring products of different thicknesses. By cooperating with the vertical rotary machine using adjustable preheating lamps, the cylindrical surface and both end faces of the ring product are heated synchronously and uniformly, which improves the toughness of the quartz material, avoids the temperature gradient caused by direct polishing, suppresses the generation of microcracks caused by thermal stress during polishing, and improves the product qualification rate. The vertical rotary machine can drive the ring product to rotate axially. At the same time, the rotation of the turntable allows the polishing end on the robotic arm to cover the entire surface of the product, eliminating polishing dead angles, eliminating the need for secondary clamping, improving processing efficiency, and shortening the production cycle.

[0045] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-9 As shown, an automatic polishing device for quartz ring parts.

[0046] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0047] An automatic polishing device for quartz ring parts includes a robot base 1, a robotic arm 2 mounted on the robot base 1, a polishing end 3 mounted at the end of the robotic arm 2, a vertical rotating machine mounted on one side of the robot base 1, a ring product 4 movably mounted on the vertical rotating machine, the axis of the ring product 4 being horizontal, and a preheating lamp 8 movably mounted on the outside of the vertical rotating machine, the preheating lamp 8 being correspondingly mounted to the ring product 4.

[0048] It should be noted that the annular product 4 is made of quartz material. The device is fixed in the quartz parts production workshop and connected to a power supply and control unit. The control unit can be a control panel with a built-in microcontroller. The microcontroller can be programmed with software. By writing the control program, the device can be controlled. Since this is existing technology, it will not be described in detail here. The robot base 1, the robotic arm 2 and the polishing end 3 form a polishing robot. Through the operation of the robotic arm 2, the polishing end 3 is moved to perform polishing operation on the annular product 4. This is a common polishing operation in existing technology. Since this is existing technology, it will not be described in detail here.

[0049] Specifically, the vertical rotating machine includes a V-type drive unit 5, on which adjustable rollers 6 are symmetrically arranged, and a pressing unit 7 is installed on the V-type drive unit 5, which is movably attached to the side wall of the annular product 4.

[0050] Specifically, the adjustable roller 6 includes a support roller 61, a fixed ring 62 is fixedly provided on one side of the support roller 61, and an adjuster is provided on the other side of the support roller 61.

In the second position, the support roller 61, the fixed ring 62 and the adjuster are all movably attached to the annular product 4.

[0051] It should be noted that the annular product 4 stands on the support roller 61 of the adjusting rollers 6 on both sides of the V-type drive unit 5, that is, the axis of the annular product 4 is horizontal, and the annular product 4 is in contact with the fixed ring 62. This is the first position of the adjusting roller 6. The adjusting device works to make the adjusting device contact the side wall of the annular product 4. This is the second position of the adjusting roller 6. The support roller 61, the fixed ring 62 and the adjusting device provide stable support for the annular product 4. This is suitable for supporting thinner annular products 4, and is also suitable for annular products 4 of different thicknesses. The operation of the V-type drive unit 5 can make the adjusting rollers 6 on both sides rotate, driving the annular product 4 to rotate at a low speed and stably. At the same time, the preheating lamp 8 is aligned with the annular product 4 to heat the annular product 4. Heating, through the rotation of the annular product 4, allows different parts of the annular product 4 to be aligned with the preheated lamp 8, ensuring uniform heating of the annular product 4, improving the toughness of the quartz parts, avoiding the formation of a temperature gradient in the quartz material when the polishing end 3 is working, reducing thermal stress, avoiding micro-cracks at the polishing position, and improving the product qualification rate. At the same time, the rotation of the annular product 4 makes it easier for the robotic arm 2 to drive the polishing end 3 to be aligned with different parts of the annular product 4, eliminating polishing dead angles, eliminating the need for secondary clamping, improving processing efficiency, and shortening the production cycle. Based on the support of the annular product 4 by the adjustable rollers 6 on both sides, the pressing part 7 is attached to the side wall of the annular product 4, strengthening the support effect of the annular product 4 and ensuring the stability of the rotation of the annular product 4.

[0052] Specifically, the preheating lamp 8 includes a lamp holder, on which a cylindrical heating end and two disc heating ends are provided.

[0055] It should be noted that the bushing 64 is used to connect the rotating shaft 63 and the support roller 61, and the flange 65 is used to install the first electric push rod 66. Through the operation of the first electric push rod 66, the distance between the fixed ring 62 and the push ring 67 can be adjusted. In the second position, the support roller 61, the fixed ring 62 and the push ring 67 in the adjuster are movably attached to the annular product 4.

[0056] Specifically, both the cylindrical heating end and the two disc heating ends include a lead screw module 83. The lead screw module 83 is mounted on the V-type drive unit 5. A second electric push rod 84 is mounted on the moving end of the lead screw module 83. An arbitrary stop bracket 85 is mounted on the telescopic end of the second electric push rod 84. A support rod 86 is fixedly inserted on the arbitrary stop bracket 85. A quartz lamp 87 is mounted on one end of the support rod 86.

[0057] It should be noted that the operation of the lead screw module 83 can drive the second electric push rod 84 and the components on the telescopic end of the second electric push rod 84 to rise and fall. The operation of the second electric push rod 84 can drive the components on the telescopic end to rise and fall. Through the cooperation of the lead screw module 83 and the second electric push rod 84, the two-stage lifting of the arbitrary stop bracket 85, its support rod 86, and the quartz lamp 87 is realized, expanding the height adjustment range of the quartz lamp 87. The structure of the quartz lamp 87 and the working principle of heating the quartz product are existing technologies and will not be described in detail here.

The cover 854 is a flexible structure used to cover its internal components. The gas delivery pipeline connected to the quartz lamp 87 usually passes through the arbitrary stop bracket 85 to limit the gas delivery pipeline and prevent the gas delivery pipeline from loosening.

[0060] Specifically, the V-type drive unit 5 includes a base 51, a turntable 52 mounted on the base 51, a V-shaped box 53 mounted on the turntable 52, a geared motor 54 mounted at the center of the side wall of the V-shaped box 53, the drive end of the geared motor 54 extending through the outer side wall of the V-shaped box 53, a drive sprocket 55 fixedly mounted on the drive end of the geared motor 54, a rotating shaft 63 movably inserted into the V-shaped box 53 via a bearing 68, a driven sprocket 56 fixedly mounted on one end of the rotating shaft 63, a tension sprocket 57 mounted on the side wall of the V-shaped box 53, and the drive sprocket 55, the driven sprocket 56 and the tension sprocket 57 connected to each other via a chain 58;

Through the operation of the turntable 52, the V-box 53 and the components on it can drive the ring product 4 to rotate, so that the other side wall of the ring product 4 is aligned with the polishing end 3, achieving polishing without dead angles.

[0062] Specifically, the pressing part 7 includes a support 71, which is installed on the side wall of the V-shaped box 53 and is arranged on the same side as the adjusting roller 6.

[0074] Step 4: Start the V-type drive unit 5 to rotate the ring product 4, and at the same time turn on the preheating lamp 8 to heat the ring product 4. The robot base 1, the robotic arm 2 and the polishing end 3 work, and the polishing end 3 polishes the heated part of the ring product 4.

[0075] Step 5: After the cylindrical surface and one side end face of the ring product 4 are polished, the preheating lamp 8 is activated, moving the preheating lamp 8 away from the ring product 4. The turntable 52 of the V-type drive unit 5 rotates 180 degrees, turning the other side end face of the ring product 4 toward the polishing robot. The polishing end 3 continues to polish the ring product 4.

[0076] Step 6: After polishing is completed, the base 51, robotic arm 2, polishing end 3, preheating lamp 8 and V-type drive unit 5 stop working, the clamping part 7 is released, and the positioner of the adjusting roller 6 is retracted to the first position. The polished ring product 4 is then removed.
