Abstract
Description
Technical Field
[0001] This utility model relates to the field of product positioning technology, and in particular to a positioning device and processing equipment. Background Technology
[0002] After a product is formed, especially irregularly shaped products with varied structures (such as VR glasses frames), a positioning device is usually required to position it so that the processing equipment can perform precise processing. Existing positioning devices typically first support the workpiece with a support component adapted to the shape of the irregular product, and then use clamping components to press the workpiece firmly onto the support component. However, for workpieces with complex structures, tilting is prone to occur under the action of the clamping components, resulting in insufficient positioning accuracy. Utility Model Content
[0003] In view of the above situation, it is necessary to provide a positioning device and processing equipment to improve positioning accuracy.
[0004] This application provides a positioning device, including:
[0005] A support assembly includes a support member and a support member. The support member has a carrier body adapted to and used to support a workpiece. The support member is spaced apart from the carrier body and adapted to and abuts against the workpiece.
[0006] The positioning assembly includes a pusher and a clamping member. The pusher is located on one side of the carrier and is correspondingly arranged with respect to the support member. The pusher is used to push the workpiece to the support member in a horizontal direction. The clamping member is located adjacent to the carrier member and is used to clamp the workpiece to the carrier in a vertical direction after the pusher pushes the workpiece.
[0007] In practical application, the aforementioned positioning device firstly supports the workpiece using a carrier adapted to the workpiece. Next, a support member abuts against the side wall of the workpiece to support it. Then, a pusher member horizontally pushes the workpiece to the support member, clamping the positioned workpiece horizontally against the support member. This allows the pusher and support member to provide lateral support for the workpiece, preventing it from swaying, shifting, or tilting. Finally, a clamping member vertically clamps the workpiece against the carrier, achieving simultaneous clamping of the positioned workpiece in both vertical and horizontal directions, thus improving positioning accuracy. In this way, by having the support member abut against the side wall of the workpiece to support it, and the pusher member horizontally pushing the workpiece to the support member to clamp it horizontally, the support member and pusher member provide lateral support, preventing swaying, shifting, or tilting. Finally, the clamping member vertically clamps the workpiece against the carrier, achieving simultaneous clamping of the positioned workpiece in both horizontal and vertical directions, thereby improving positioning accuracy.
[0008] In some embodiments, the actuating element includes:
[0009] A drive unit is located on one side of the support member;
[0010] A connecting body is connected to the push drive body, and the connecting body is used to move closer to the support member under the drive of the push drive body;
[0011] A pushing body, protruding from the side of the connecting body facing the support member, has a cross-sectional area smaller than that of the connecting body in the vertical direction. The pushing body is used to push the workpiece towards the support member under the influence of the connecting body.
[0012] A sensor, electrically connected to the push drive body, is used to detect the pushing force applied to the workpiece by the push drive body.
[0013] In some embodiments, the support member has an adsorption hole on the side facing the carrier, the adsorption hole being configured to communicate with an air source to adsorb the workpiece and make the workpiece abut against the support member when the air source is connected.
[0014] In some embodiments, the clamping element further includes:
[0015] A clamping drive body is disposed adjacent to the carrier component;
[0016] A linkage body, connected to the clamping drive body, is configured to rotate under the drive of the clamping drive body, and to move closer to the support body after rotating above it; and
[0017] A clamping body protrudes from the side wall of the linkage body and is perpendicularly connected to the linkage body. The clamping body is used to clamp the workpiece to the carrier body under the drive of the linkage body.
[0018] In some embodiments, the linkage includes a linkage part and a limiting part. The linkage part is connected to the pressing drive body. The limiting part and the pressing body are both disposed on the linkage part and spaced apart along the periphery of the linkage part. The limiting part is provided with a limiting hole that penetrates the limiting part.
[0019] The bearing assembly further includes a guide member, which is arranged vertically corresponding to the limiting hole. The guide member is inserted into the limiting hole to guide the movement direction of the limiting part.
[0020] In some embodiments, the limiting part is provided with two limiting holes at intervals, and the number of guide members is two. The two guide members correspond one-to-one with the two limiting holes, and the two guide members are respectively inserted into the corresponding limiting holes to restrict the rotation of the limiting part.
[0021] In some embodiments, the clamping body is provided with a clearance groove that penetrates the clamping body, and a clearance space is formed between the clamping body and the linkage body. The clearance groove and the clearance space are used to respectively avoid the preset area of the workpiece.
[0022] In some embodiments, both the clamping body and the pushing body are flexible bodies.
[0023] In some embodiments, the carrier is provided with an air blowing hole, which is configured to communicate with an air source and is used to blow air into the carrier when the air source is connected.
[0024] This application also provides a processing apparatus, including:
[0025] The aforementioned positioning device is used to position a workpiece; and
[0026] A processing device is disposed on one side of the supporting component, and the processing device is used to process the workpiece positioned on the positioning device.
[0027] In practical applications, the aforementioned processing equipment uses an adsorption hole to adsorb the workpiece onto the support component under the guidance of an air source. The pusher then pushes the workpiece horizontally onto the support component to clamp and position the workpiece horizontally. This allows the support component and the pusher to provide lateral support for the workpiece, preventing it from shaking, shifting, or tilting. Finally, the clamping component clamps the workpiece vertically onto the carrier, achieving simultaneous clamping and positioning of the workpiece in both the horizontal and vertical directions. This improves positioning accuracy and facilitates precise processing of the positioned workpiece by the processing device. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0035] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.
[0036] Please see Figure 1This application provides a processing device 200, which includes a positioning device 100 and a processing device 201. The positioning device 100 includes a support component 10 and a positioning component 20, and is used to position a workpiece 300. The processing device 201 is disposed on one side of the support component 10 and is used to process the positioned workpiece 300. Exemplarily, the processing device 201 can be any processing part, processing body, or similar processing unit capable of processing the workpiece 300. The workpiece 300 is an irregularly shaped product, such as a VR glasses frame.
[0037] Please see Figure 1 and Figure 2 The bearing assembly 10 includes a bearing member 11 and a support member 12. The bearing member 11 has a bearing body 111, which is adapted to and used to support the workpiece 300. The support member 12 is spaced apart from the bearing body 111 and is adapted to the workpiece 300. The positioning assembly 20 includes a pushing member 21 and a clamping member 22. The pushing member 21 is located on one side of the bearing member 11 and is correspondingly arranged with respect to the support member 12. The pushing member 21 is used to push the workpiece 300 to the support member 12 in the horizontal direction. The clamping member 22 is arranged adjacent to the bearing member 11 and is used to clamp the workpiece 300 to the bearing body 111 in the vertical direction after the pushing member 21 pushes the workpiece 300.
[0038] In practical application, the aforementioned positioning device 100 firstly carries the workpiece 300 on a carrier 111 adapted to the workpiece 300; then, a support member 12 abuts against the side wall of the workpiece 300 to support it; next, a pusher 21 pushes the workpiece 300 to the support member 12 in a horizontal direction to clamp and position the workpiece 300 to the support member 12 in a horizontal direction, so that the pusher 21 and the support member 12 provide lateral support for the workpiece 300, preventing the workpiece 300 from shaking, shifting, or tilting; finally, a clamping member 22 clamps the workpiece 300 to the carrier 111 in a vertical direction, thereby achieving simultaneous clamping and positioning of the workpiece 300 in both the vertical and horizontal directions, improving positioning accuracy. Thus, the support member 12 abuts against the side wall of the workpiece 300 to support the workpiece 300, and the pusher 21 pushes the workpiece 300 to the support member 12 in the horizontal direction to clamp and position the workpiece 300 in the horizontal direction. This allows the support member 12 and the pusher 21 to provide lateral support for the workpiece 300, preventing the workpiece 300 from shaking, shifting, or tilting. Then, the clamping member 22 clamps the workpiece 300 to the carrier 111 in the vertical direction, thereby achieving simultaneous clamping and positioning of the workpiece 300 in both the horizontal and vertical directions, which improves the positioning accuracy.
[0039] It is understandable that the carrier 111 can be a groove, protrusion, curved surface, etc., that are adapted to the workpiece 300.
[0040] Please see Figure 1 In this embodiment, there are multiple sets of bearing components 10 and positioning components 20. The multiple sets of bearing components 10 and positioning components 20 are arranged at intervals along the structural extension direction of the workpiece 300 to position the workpiece 300 at different positions, thereby increasing the positioning device 100's ability to position the workpiece 300 and improving the positioning stability of the positioning device 100.
[0041] Please see Figure 3 In some embodiments, the pushing member 21 includes a pushing drive body 211, a connecting body 212, and a pushing body 213. The pushing drive body 211 is disposed on one side of the support member 11, and the connecting body 212 is connected to the pushing drive body 211. The connecting body 212 is used to move closer to the support member 12 under the drive of the pushing drive body 211. The pushing body 213 protrudes from the side of the connecting body 212 facing the support member 12. In the vertical direction, the cross-sectional area of the pushing body 213 is smaller than the cross-sectional area of the connecting body 212. The pushing body 213 is used to push the workpiece 300 to the support member 12 under the drive of the connecting body 212. Exemplarily, the pushing drive body 211 can be a cylinder.
[0042] Thus, by setting the specific structure of the pusher 21, since the cross-sectional area of the pusher 213 is smaller than that of the connecting body 212, the contact area between the pusher 21 and the workpiece 300 is reduced. This makes it easier for the pusher 21 to adapt to workpieces 300 with complex shapes and large curvature changes, allowing the pusher 21 to flexibly position the workpiece 300 and improving the flexibility of the pusher 21 in use.
[0043] Please continue reading. Figure 3 In some embodiments, the pusher 21 further includes a sensor 214 electrically connected to the push drive 211. The sensor 214 is used to detect the pushing force applied to the workpiece 300 by the push drive 211 driving the pusher 213. Exemplarily, the sensor 214 can be any detection part, detection body, or similar detection element capable of detecting the pushing force applied to the workpiece 300 by the push drive 211 driving the pusher 213, such as a pressure sensor.
[0044] Thus, by setting the aforementioned sensor 214, the sensor 214 can detect in a timely manner the pushing force applied to the workpiece 300 by the driving body 211 driving the driving body 213, so as to accurately control the magnitude of the pushing force applied to the workpiece 300 by the driving body 213, avoiding deformation or damage to the workpiece 300 due to excessive pushing force applied to the workpiece 300, or failure of the driving body 213 to accurately position the workpiece 300 to the support member 12 due to insufficient pushing force, thereby ensuring that the driving body 21 stably and accurately positions the workpiece 300 to the support member 12.
[0045] Please see Figure 1 and Figure 2 In some embodiments, the support member 12 is provided with an adsorption hole 121 on the side facing the carrier 111. The adsorption hole 121 is configured to communicate with an air source so as to adsorb the workpiece 300 and make the workpiece 300 abut against the support member 12 under the conduction of the air source.
[0046] Thus, by setting the above-mentioned adsorption hole 121, the adsorption hole 121 can adsorb the workpiece 300 under the conduction of the air source, so that the workpiece 300 can stably abut against the support member 12, ensuring that the support member 12 stably supports the workpiece 300 and improving the support stability.
[0047] It is understood that there are multiple adsorption holes 121. The multiple adsorption holes 121 are evenly distributed on the support 12, which is conducive to applying suction force evenly to the workpiece 300 and ensuring that the workpiece 300 is stably adsorbed to the support 12.
[0048] Please see Figure 3 In some embodiments, the clamping member 22 further includes a clamping drive body 221, a linkage body 222, and a clamping body 223. The clamping drive body 221 is disposed adjacent to the carrier 11, and the linkage body 222 is connected to the clamping drive body 221. The linkage body 222 is used to rotate under the drive of the clamping drive body 221, and moves closer to the carrier 111 after rotating above the carrier 111. The clamping body 223 protrudes from the side wall of the linkage body 222 and is perpendicularly connected to the linkage body 222. The clamping body 223 is used to clamp the workpiece 300 to the carrier 111 under the drive of the linkage body 222. Exemplarily, the clamping drive body 221 can be a rotary telescopic cylinder.
[0049] Thus, by setting the specific structure of the clamping member 22, the clamping drive body 221 first drives the linkage body 222 to rotate the clamping body 223 to the top of the carrier body 111, so that the clamping body 223 corresponds to the carrier body 111. Then, the clamping drive body 221 drives the clamping body 223 to move closer to the carrier body 111, so as to ensure that the clamping body 223 stably clamps the workpiece 300 to the carrier body 111, thereby improving the positioning stability.
[0050] Please see Figure 1 and Figure 3 In some embodiments, the linkage 222 includes a linkage part 2221 and a limiting part 2222. The linkage part 2221 is connected to the pressing drive body 221. The limiting part 2222 and the pressing body 223 are both disposed on the linkage part 2221 and spaced apart along the periphery of the linkage part 2221. The limiting part 2222 is provided with a limiting hole 2222a that penetrates through the limiting part 2222. The bearing assembly 10 also includes a guide member 13, which is vertically corresponding to the limiting hole 2222a. The guide member 13 is used to be inserted into the limiting hole 2222a to guide the movement direction of the limiting part 2222.
[0051] Thus, by setting the specific structure of the linkage 222, when the linkage 2221 drives the clamping body 223 to rotate above the carrier 111 under the drive of the clamping drive 221, the limiting hole 2222a corresponds to the guide member 13. The guide member 13 is inserted into the limiting hole 2222a when the clamping body 223 moves close to the carrier 111 to guide the movement direction of the limiting part 2222 and the clamping body 223, ensuring that the clamping body 223 moves accurately close to the workpiece 300 carried by the carrier 111, which is conducive to the clamping body 223 accurately clamping the workpiece 300 to the carrier 111 and improving the positioning accuracy.
[0052] Please continue reading. Figure 1 and Figure 3 In some embodiments, the limiting part 2222 is provided with two limiting holes 2222a at intervals, and there are two guide members 13. The two guide members 13 correspond one-to-one with the two limiting holes 2222a. The two guide members 13 are used to be inserted into the corresponding limiting holes 2222a respectively to restrict the rotation of the limiting part 2222.
[0053] Thus, by setting two guide members 13 corresponding one-to-one with two limiting holes 2222a, the two guide members 13 are respectively inserted into the corresponding limiting holes 2222a when the clamping body 223 moves close to the carrier body 111, so as to restrict the rotation of the limiting part 2222 and the clamping body 223 during the clamping of the workpiece 300, thereby adjusting the orientation and position of the limiting part 2222 and the clamping body 223, so as to avoid misalignment between the clamping body 223 and the workpiece 300, which is conducive to the clamping body 223 accurately clamping the workpiece 300 to the carrier body 111.
[0054] Please see Figure 3 In some embodiments, the clamping body 223 is provided with a relief groove 2232, which penetrates the clamping body 223, and a clearance space 2231 is formed between the clamping body 223 and the linkage body 222. The relief groove 2232 and the clearance space 2231 are used to avoid the preset area of the workpiece 300.
[0055] Since the preset area of the workpiece 300 has a special structure, or the processing device 201 needs to process the preset area of the workpiece 300, by setting a clearance groove 2232 on the clamping body 223 and setting a clearance space 2231 between the clamping body 223 and the linkage body 222, the clearance groove 2232 and the clearance space 2231 can avoid the preset area of the workpiece 300 when the clamping body 223 presses the workpiece 300 against the carrier body 111, so as to prevent the clamping body 223 from blocking or pressing the preset area of the workpiece 300, ensuring that the preset area of the workpiece 300 is not blocked or damaged, which is beneficial for the clamping body 223 to be applicable to workpieces 300 of different shapes, and improves versatility and applicability.
[0056] In some embodiments, both the clamping body 223 and the pushing body 213 are flexible bodies. For example, the flexible body can be made of materials such as urethane, silicone, or polyurethane.
[0057] Thus, by setting both the clamping body 223 and the pushing body 213 to be flexible, it is beneficial for the clamping body 223 and the pushing body 213 to adapt to the shape and surface characteristics of the workpiece 300. In addition, the flexible body can generate a certain elastic deformation when it contacts the workpiece 300, so that the clamping body 223 and the pushing body 213 can better fit the surface of the workpiece 300, thereby improving the positioning accuracy. At the same time, the flexible body has a certain buffering effect, avoiding excessive force applied to the workpiece 300 by the clamping body 223 and the pushing body 213, thereby preventing the workpiece 300 from being damaged during the positioning process, improving the positioning quality and the quality of the workpiece 300.
[0058] Please see Figure 2 In some embodiments, the carrier 111 is provided with an air blowing hole 1111, which is configured to communicate with an air source and is used to blow air to the carrier 111 when the air source is connected.
[0059] Since the processing device 201 generates a large amount of debris after processing the positioned workpiece 300, and the temperature of the processed workpiece 300 also increases, by setting the aforementioned air blowing hole 1111, the air blowing hole 1111 blows air toward the carrier 111 after processing to cool the workpiece 300 carried by the carrier 111, preventing the workpiece 300 from deforming due to the temperature rise, thus improving the quality of the workpiece 300 and the processing quality. In addition, after the processed workpiece 300 is removed, the air blowing hole 1111 blows air toward the carrier 111 to remove dirt, debris, etc. attached to the carrier 111, avoiding the debris adhering to the carrier 111 from interfering with the positioning operation of the next workpiece 300 to be processed, thereby improving the positioning accuracy.
[0060] It is understandable that there can be multiple air holes 1111, and multiple air holes 1111 are evenly distributed on the carrier 111 to improve cleaning efficiency and cooling efficiency.
[0061] The working process of the aforementioned processing equipment 200 is roughly as follows:
[0062] First, the carrier 111, which is adapted to the workpiece 300, carries the workpiece 300;
[0063] Next, with the air source in operation, the adsorption hole 121 adsorbs the workpiece 300 and abuts against the support member 12, so that the support member 12 is attached to the workpiece 300 and supports the workpiece 300.
[0064] Then, the driving body 211 drives the connecting body 212 to move the driving body 213 closer to the support member 12, so that the driving body 213 pushes the workpiece 300 to the support member 12 in the horizontal direction, so as to clamp and position the workpiece 300 to the support member 12 in the horizontal direction, so that the driving body 213 and the support member 12 provide lateral support for the workpiece 300, and prevent the workpiece 300 from shaking, shifting, tilting or other situations.
[0065] Finally, the clamping drive body 221 drives the linkage body 222 to rotate the clamping body 223 above the carrier body 111, so that the clamping body 223 corresponds to the carrier body 111. The clamping drive body 221 then drives the clamping body 223 to move closer to the carrier body 111 to ensure that the clamping body 223 stably clamps the workpiece 300 to the carrier body 111 in the vertical direction, thereby achieving simultaneous clamping and positioning of the workpiece 300 in the vertical and horizontal directions, thereby improving the positioning accuracy.
[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
