Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a clamping fixture which can prevent plasma burns and keep a non-working area of ​​a product away from air. Background Art

[0002] In an automated processing line, an automated conveying device is usually used to transport the workpiece to each processing station, and cooperates with the processing equipment at each processing station to realize fully automated step-by-step processing of the workpiece. In order to better position and transport the product, it is usually necessary to install a workpiece clamping fixture on the set conveying device, which is the so-called workpiece carrier. The workpiece to be processed is loaded on the set workpiece clamping fixture, and then driven by the conveying device to move along a predetermined path and pass through each processing station in turn.

[0003] At present, before various existing smart devices, such as the glass screen of a smart phone, are installed to their main frames by injecting glue around the periphery of their fixing surfaces, it is necessary to spray plasma particles at high temperature around the periphery of the fixing surfaces, the purpose of which is to enhance the adhesion of the glue.

[0004] The existing workpiece clamping fixture for clamping the relevant glass screen usually uses a plurality of jaws made of peek material that does not damage the workpiece to clamp and fix its periphery. During use, when high-temperature plasma particles are sprayed downward on the periphery of the upper end surface (fixing surface) of the clamped glass screen, long-term use will cause the plurality of jaws made of peek material that does not damage the workpiece and the area supported by the periphery of the bottom surface of the glass screen to be easily burned by high temperature, resulting in a short service life of the workpiece clamping fixture. In addition, the existing corresponding workpiece clamping fixture has a relatively complex structure of the driving component that needs to control the synchronous opening and closing of the plurality of jaws arranged in a circle to the opposite sides or to the opposite sides, which makes its design cost also high.

[0005] In this regard, the inventor of this patent combined his experience, conducted in-depth thinking on the problems encountered in his work, read a large amount of scientific research materials and literature, and conducted searches and novelties, and gradually conceived and designed this application to solve the relevant technical problems.

[0033] The beneficial effects of the utility model are:

[0089] The clamping fixture 1000 for preventing plasma burns and keeping the non-working area of ​​the product free from air according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0090] Reference Figures 1 to 5 As shown, the clamping fixture 1000 for preventing plasma burns and avoiding air in the non-working area of ​​the product provided according to the embodiment of the utility model comprises a supporting plate 10 and a vacuum suction plate 20 provided on the upper end surface of the supporting plate 10 for adsorbing and fixing the workpiece product 2000;

[0091] Among them, the outer circumferential size of the vacuum suction plate 20 is slightly smaller than the outer circumferential size of the workpiece product 2000; the vacuum suction plate 20 is provided with a first elastic clamping member 201 on the left side, a second elastic clamping member 202 on the front side, a third elastic clamping member 203 on the rear side, and a fourth elastic clamping member 204 on the right side; the first elastic clamping member 201, the second elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204 are used to gather together in the horizontal direction and clamp and position the workpiece product 2000 at the first position when the workpiece product 2000 is placed on the upper end surface of the vacuum suction plate 20, so that when the workpiece product 2000 is adsorbed and fixed by the vacuum suction plate 20 at the corresponding first position, the periphery of its lower bottom surface is not supported by the vacuum suction plate 20.

[0092] Based on the above, it is clear that when the present application is implemented, it is mainly used as a clamping fixture 1000 to prevent plasma burns and to avoid air in non-working areas of the product.

[0093] Specifically, when applying the present application, the workpiece product 2000 (smart device glass screen) to be processed is placed on the upper end surface of the vacuum suction plate 20 with the fixed surface facing upward, so that the first elastic clamp 201, the second elastic clamp 202, the third elastic clamp 203 and the fourth elastic clamp 204 are gathered together in the horizontal direction to clamp and position it in the first position, and then, the vacuum suction plate 20 is used to adsorb and fix the workpiece product 2000 (smart device glass screen) to be processed, and then, a plasma spraying device can be used to surround the workpiece product 2000 (smart device glass screen) to be processed and spray plasma particles on the periphery of its fixed surface downward, so as to increase the adhesion of the glue when the glue is subsequently poured in the relevant parts to fix it to the matching main frame.

[0094] Obviously, the use of the above-mentioned application will have the following technical effects:

[0095] On the one hand, when applying the present application, when the workpiece product 2000 (glass screen of smart device) to be processed is placed on the upper end surface of the vacuum suction plate 20 with the fixed surface facing upward, the first elastic clamp 201, the second elastic clamp 202, the third elastic clamp 203 and the fourth elastic clamp 204 can be brought together in the horizontal direction to clamp and position it in the first position. In this way, the workpiece product 2000 (glass screen of smart device) to be processed can be accurately positioned when it is placed and fixed, so that plasma spraying equipment can be used to spray plasma particles accurately at the preset position around the fixed surface of the workpiece product 2000 (glass screen of smart device) to be processed downward, so that the present application has good reliability.

[0096] On the other hand, when the workpiece product 2000 (glass screen of smart device) to be processed is adsorbed and fixed by the vacuum suction plate 20 at the corresponding first position, the peripheral edge of its lower bottom surface is not supported by the vacuum suction plate 20. In this way, the peripheral edge of the lower bottom surface of the workpiece product 2000 (glass screen of smart device) to be processed is kept free, so that the high temperature generated by the plasma particles sprayed downward by the plasma spraying equipment can be better prevented from burning the vacuum suction plate 20, making the application more reliable and safer to use and having a long service life.

[0097] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0098] Furthermore, in the specific implementation, Figure 1 and Figure 3 As shown, according to one embodiment of the utility model, the present application further includes a driving mechanism A30;

[0099] Among them, the driving mechanism A30 is abutted against or connected to the second elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204, and is used to drive the second elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204 to move horizontally away from the vacuum suction plate 20 to a second position, so that the area enclosed by them and the first elastic clamping member 201 forms a workpiece product picking and placing space.

[0100] In this regard, it is clear that before using the present application, the second elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204 can be driven in advance by the driving mechanism A30 to move horizontally away from the vacuum suction plate 20 to the second position, so that the area enclosed by them and the first elastic clamping member 201 forms a workpiece product placement space. At this time, the workpiece product 2000 (smart device glass screen) to be processed can be placed with the fixed surface facing up on the upper end surface of the vacuum suction plate 20, and then, the second elastic The third elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204 can be gathered together in the horizontal direction to clamp and position it in the first position, and then the vacuum suction plate 20 can be used to adsorb and fix the workpiece product 2000 (smart device glass screen) to be processed, and then, the plasma spraying equipment can be used to surround the workpiece product 2000 (smart device glass screen) to be processed and spray plasma particles downward on the periphery of its fixed surface, so as to increase the adhesion of the glue when the glue is subsequently poured in the relevant parts to fix it to the matching main frame.

[0101] On the contrary, after the related operations of spraying plasma particles on the periphery of the fixed surface of the workpiece product 2000 (glass screen of smart device) to be processed are completed, the driving mechanism A30 can be used to drive the second elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204 to move horizontally away from the vacuum suction plate 20 to the second position. At this time, it is convenient to take out the corresponding workpiece product 2000 (glass screen of smart device) after the related operations of spraying plasma particles on the periphery of the fixed surface are completed from the workpiece product picking and placing space, and replace the workpiece product 2000 (glass screen of smart device) to be processed therein, and the operation can be repeated in this way, so that the present application can be used continuously.

[0102] Furthermore, when the second elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204 are brought together in the horizontal direction to clamp and position the workpiece product 2000 (smart device glass screen) to be processed at the first position, the vacuum suction plate 20 can be used to adsorb and fix it, and then, the second elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204 can be driven by the driving mechanism A30 again to move horizontally back to the vacuum suction plate 20 to the second position, so that the back A certain distance away from the periphery of the adsorbed and fixed workpiece product 2000 (smart device glass screen) to be processed, at this time, when a plasma spraying device is used to surround the workpiece product 2000 (smart device glass screen) to be processed and spray plasma particles downward at a preset position on the periphery of its fixed surface, the high temperature generated is not easily transmitted to the second elastic clamp 202, the third elastic clamp 203 and the fourth elastic clamp 204, so that the second elastic clamp 202, the third elastic clamp 203 and the fourth elastic clamp 204 have a good effect of preventing high temperature burns.

[0103] Furthermore, in the specific implementation, Figure 2 and Figure 3 As shown, according to one embodiment of the utility model, the present application further includes a driving mechanism B40;

[0104] The driving mechanism B40 is connected to the first elastic clamping member 201 to drive the first elastic clamping member 201 to move horizontally away from the vacuum suction plate 20 to the second position.

[0105] From this, it can be clearly seen that:

[0106] On the one hand, when the driving mechanism B40 is used to drive the first elastic clamping member 201 to move horizontally away from the vacuum suction plate 20 to the second position, the workpiece product placement space can be further expanded, making it easier to place the workpiece product 2000 (smart device glass screen) to be processed therein or to take out the processed workpiece product 2000 (smart device glass screen) therefrom.

[0107] On the other hand, after the workpiece product 2000 (glass screen of smart device) to be processed is clamped and positioned at the first position so as to be adsorbed and fixed by the vacuum suction plate 20, the first elastic clamping member 201 can be driven by the driving mechanism B40 to move to the second position in the horizontal direction away from the vacuum suction plate 20, so as to be a certain distance away from the periphery of the adsorbed and fixed workpiece product 2000 (glass screen of smart device) to be processed. At this time, when a plasma spraying device is used to surround the workpiece product 2000 (glass screen of smart device) to be processed and spray plasma particles downward at a preset position on the periphery of its fixed surface, the high temperature generated is not easily transmitted to the first elastic clamping member 201, so that the first elastic clamping member 201 also has a good effect of preventing high temperature burns.

[0108] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0109] In addition, in this technical solution, Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the utility model, the present application further comprises a plurality of anti-burn protection covers A50;

[0110] Among them, multiple anti-burn protection covers A50 are arranged on the supporting plate 10, and are located at the second position so that the corresponding covers move to the corresponding second positions of the first elastic clamping member 201, the second elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204.

[0111] Therefore, it can be clearly seen that after the workpiece product 2000 (glass screen of smart device) to be processed is clamped and positioned at the first position so as to be adsorbed and fixed by the vacuum suction plate 20, the second elastic clamping member 202, the third elastic clamping member 203 and the fourth elastic clamping member 204 can be driven by the driving mechanism A30 to move to the second position in the horizontal direction away from the vacuum suction plate 20, so as to be away from the periphery of the adsorbed and fixed workpiece product 2000 (glass screen of smart device) to be processed by a certain distance, and the first elastic clamping member 201 can be driven by the driving mechanism B40 to move to the second position in the horizontal direction away from the vacuum suction plate 20, so as to be away from the periphery of the adsorbed and fixed workpiece product 2000 (glass screen of smart device) to be processed. At this time, the first elastic clamp 201, the second elastic clamp 202, the third elastic clamp 203 and the fourth elastic clamp 204 will be covered by multiple pieces of the anti-burn protection cover A50, so that when the plasma spraying equipment is used to surround the workpiece product 2000 (smart device glass screen) to be processed and spray plasma particles downward at a preset position on the periphery of its fixed surface, the high temperature generated is less likely to be transmitted to the first elastic clamp 201, the second elastic clamp 202, the third elastic clamp 203 and the fourth elastic clamp 204, so that the first elastic clamp 201, the second elastic clamp 202, the third elastic clamp 203 and the fourth elastic clamp 204 are all better protected from high-temperature burns.

[0112] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be further improved.

[0113] Furthermore, in the technical solution, according to an embodiment of the utility model, the plurality of anti-burn protection covers A50 are all made of metal material, and are preferably made of stainless steel.

[0114] Therefore, it has good fire resistance, is not easy to be burned, and has a long service life.

[0115] Furthermore, in a specific implementation, according to an embodiment of the present invention, the thickness of the vacuum suction plate 20 is D, and D is ≥ 10.0 mm.

[0116] It should be noted here that according to experimental results, when the thickness of the vacuum suction plate 20 reaches 10.0 mm, it can ensure that the high temperature generated by the plasma spraying equipment used to spray plasma particles downward is not easy to burn the upper end surface of the support plate 10, making the overall reliability of the present application better.

[0117] Furthermore, in a specific implementation, according to an embodiment of the utility model, a card slot 205 is opened in the middle of the upper end surface of the vacuum suction plate 20 , and a product presence detection sensor 206 for detecting the workpiece product 2000 is fixedly installed in the card slot 205 .

[0118] Therefore, by setting the product presence detection sensor 206, it can be sensed whether there is a workpiece product 2000 on the vacuum suction plate 20, so that the main control system can control how the drive mechanism A30 and the drive mechanism B40 work according to whether there is a workpiece product 2000 on the vacuum suction plate 20, so that the use of this application will be more intelligent and automated.

[0119] And in the specific implementation, continue to compare Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the present invention, the upper end surface of the support plate 10 is provided with another vacuum suction plate 20 having the same outer circumference size as the vacuum suction plate 20 on the left side thereof for adsorbing and fixing the workpiece product 2000;

[0120] The corresponding vacuum suction plate 20 is provided with a fifth elastic clamping member 207 on the right side which is symmetrical with the first elastic clamping member 201, a sixth elastic clamping member 208 on the front side which is symmetrical with the second elastic clamping member 202, a seventh elastic clamping member 209 on the rear side which is symmetrical with the third elastic clamping member 203, and an eighth elastic clamping member 210 on the left side which is symmetrical with the fourth elastic clamping member 204;

[0121] Comparison Figure 3 and Figure 4 As shown, the driving mechanism A30 is also connected to the fifth elastic clamping member 207, so as to drive the fifth elastic clamping member 207 to move to the second position in the horizontal direction away from the corresponding other vacuum suction plate 20;

[0122] Or control Figure 3 and Figure 4 As shown, the driving mechanism B40 is also abutted against or connected to the sixth elastic clamping member 208, the seventh elastic clamping member 209 and the eighth elastic clamping member 210, so as to drive the sixth elastic clamping member 208, the seventh elastic clamping member 209 and the eighth elastic clamping member 210 to move to the second position in the horizontal direction away from the corresponding other vacuum suction plate 20, so that the area enclosed by the sixth elastic clamping member 208, the seventh elastic clamping member 209 and the eighth elastic clamping member 210 and the fifth elastic clamping member 207 form a workpiece product placement space;

[0123] And contrast Figure 1 , Figure 2 and Figure 3As shown, the upper end surface of the support plate 10 is also provided at the second position with a plurality of anti-burn protective covers B60 including the fifth elastic clamp 207, the sixth elastic clamp 208, the seventh elastic clamp 209 and the eighth elastic clamp 210 for correspondingly covering and moving to the corresponding second position.

[0124] In this regard, it is clear that;

[0125] On the one hand, the comparison Figure 5 As shown, the present application uses two of the vacuum suction plates 20 to work synchronously, so that the plasma particle spraying related operations can be performed on the preset positions on the periphery of the fixed surfaces of two workpiece products 2000 (smart device glass screens) that need to be processed at the same time, which can greatly improve the working effect and greatly speed up the processing cycle. In addition, during the related operation process, they all have the same use effect, that is, the anti-scaling effect of each component of the present application is good, so that the overall service life of the present application is long.

[0126] On the other hand, the driving mechanism A30 and the driving mechanism B40 can work synchronously to control the first elastic clamp 201, the second elastic clamp 202, the third elastic clamp 203, the fourth elastic clamp 204, the fifth elastic clamp 207, the sixth elastic clamp 208, the seventh elastic clamp 209 and the eighth elastic clamp 210 to synchronously move the vacuum suction plate 20 in the horizontal direction away from the corresponding position to the second position to facilitate the placement of the workpiece product 2000 (smart device glass screen). In this process, the driving mechanism B40 cooperates with the driving mechanism A30 to help synchronously control the first elastic clamp 201 in the horizontal direction away from the vacuum suction plate 2 0 moves to the second position, and the driving mechanism A30 cooperates with the driving mechanism B40 to help synchronously control the fifth elastic clamping member 207 to move the vacuum suction plate 20 to the second position in the horizontal direction away from the corresponding position. Compared with the traditional double-station clamping fixture with double workpiece carriers (equivalent to the vacuum suction plate 20 of the present application), at least four driving mechanisms are required to control the two groups of clamping members in four directions to gather together or open away from each other synchronously. The present application only needs two driving mechanisms, namely the driving mechanism A30 and the driving mechanism B40, which can greatly reduce the use cost of the driving mechanism and greatly reduce the assembly components of the present application, making the overall structure more compact and occupying less space.

[0127] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be further improved.

[0128] It should be added that in the specific implementation, Figure 3 and Figure 4As shown, according to one embodiment of the utility model, the present application further comprises a bottom plate 70 for supporting the supporting plate 10;

[0129] On this basis, in a specific solution, the driving mechanism A30 of the present application includes left and right slide rails A301, a linkage frame A302, and a push cylinder A303 for driving the linkage frame A302 to slide left and right along the left and right slide rails A301, which are arranged on the upper end surface of the bottom plate 70 and located at the bottom of the right half of the supporting plate 10;

[0131] When the push cylinder A303 pushes the linkage frame A302 to move rightward along the left and right slide rails A301 by a preset stroke, the second elastic clamping member 202 will be pushed to move forward, the third elastic clamping member 203 will be pushed to move backward, and the fourth elastic clamping member 204 and the fifth elastic clamping member 207 will be driven to move rightward, so that they can be synchronously driven to move from the first position to the second position;

[0132] On the contrary, when the pushing cylinder A303 pulls back the linkage frame A302 so that it moves to the left along the left and right slide rails A301 by the preset stroke, the second elastic clamp 202, the third elastic clamp 203, the fourth elastic clamp 204 and the fifth elastic clamp 207 can be elastically reset synchronously to move from the second position to the first position synchronously.

[0133] On this basis, in the specific plan, continue to compare Figure 3and Figure 4 As shown, according to an embodiment of the present utility model, the driving mechanism B40 includes left and right slide rails B401 provided on the upper end surface of the bottom plate 70 and located at the bottom of the left half of the supporting plate 10, a linkage frame B402, and a push cylinder B403 for driving the linkage frame B402 to slide left and right along the left and right slide rails B401;

[0134] Among them, the linkage frame B402 is provided with a first oblique push block C4021 on the front side and a first oblique push block D4022 on the rear side; the first oblique push block C4021 has a first oblique push surface C40211 inclined toward the right front; the first oblique push block D4022 has a first oblique push surface D40221 inclined toward the right rear; the sixth elastic clamp 208 and the seventh elastic clamp 209 are configured to be slidable in the front and rear directions and are arranged on the upper end surface of the bottom plate 70, and the rear end of the sixth elastic clamp 208 and the front end of the seventh elastic clamp 209 are both formed into a pointed shape, and are correspondingly provided There is a roller B90 that abuts against the first inclined push surface C40211 and the first inclined push surface D40221; the front end of the sixth elastic clamp 208 and the rear end of the seventh elastic clamp 209 are correspondingly provided with a pressure-relief spring C120 connected to the bottom plate 70 and capable of restoring; the left end of the linkage frame B402 is connected to or abuts against the eighth elastic clamp 210, and the right end is connected to the first elastic clamp 201; the left end of the eighth elastic clamp 210 and the left end of the first elastic clamp 201 are correspondingly provided with a pressure-relief spring D130 connected to the bottom plate 70 and capable of restoring;

[0135] When the push cylinder B403 pushes the linkage frame B402 to move to the left along the left and right slide rails B401 by a preset stroke, the sixth elastic clamping member 208 will be pushed to move forward, the seventh elastic clamping member 209 will be pushed to move backward, and the first elastic clamping member 201 and the eighth elastic clamping member 210 will be driven to move to the left, so that they can be synchronously driven to move from the first position to the second position;

[0136] On the contrary, when the pushing cylinder B403 pulls back the linkage frame B402 so that it moves to the right along the left and right slide rails B401 for the preset stroke, the sixth elastic clamp 208, the seventh elastic clamp 209, the eighth elastic clamp 210 and the first elastic clamp 201 can be elastically reset synchronously to synchronously move from the second position to the first position.

[0137] The working principle of the driving mechanism A30 described in the above-mentioned application to control the second elastic clamping member 202, the third elastic clamping member 203, the fourth elastic clamping member 204 and the fifth elastic clamping member 207 to gather together or open away from each other, and the working principle of the driving mechanism B40 to control the sixth elastic clamping member 208, the seventh elastic clamping member 209, the eighth elastic clamping member 210 and the first elastic clamping member 201 to gather together or open away from each other, are basically the same as the working principle of the driving mechanism used in the invention patent "workpiece clamping carrier" with application number "202410046101.6" previously applied by the applicant of the present patent to drive its synchronous clamping mechanism to gather together or open away from each other synchronously, so the specific details of the present application will not be elaborated here.

[0138] It is further necessary to add that, in the specific implementation, according to the clamping fixture 1000 for preventing plasma burns and avoiding air in the non-working area of ​​the product provided in the embodiment of the utility model, the pushing cylinder A303 and the pushing cylinder B403 used in this application can be equivalently replaced by other pushing parts, such as using a screw-driven linear module and a cylinder-driven linear module, etc.

[0139] Furthermore, it should be noted that, for the first elastic clamping member 201 and the fifth elastic clamping member 207 of the present application, their bottoms are staggered so that they are correspondingly staggeredly connected to the linkage frame B402 and the linkage frame A302, so that they do not interfere with each other when moving between the first position and the second position along the left and right directions, and the anti-burn protection cover A50 for covering the first elastic clamping member 201 at the second position and the anti-burn protection cover B60 for covering the fifth elastic clamping member 207 at the second position are preferably an integrally formed structure.

[0142] Other embodiments and the like are not described here by way of example.

[0143] To sum up, the clamping fixture 1000 for preventing plasma burns and avoiding air in the non-working area of ​​the product provided in the present application, in specific implementation, uses two vacuum suction plates 20 to work synchronously, so that the plasma particle spraying related operations can be performed on the preset positions on the periphery of the fixed surfaces of two workpiece products 2000 (smart device glass screens) that need to be processed at the same time, which can greatly improve the working effect and greatly speed up the processing cycle, and in the related operation process, they all have the same use effect, that is, the anti-burn effect of each component of the present application is good, so that the overall service life of the present application is long.
