Description

Technical Field

[0001] The present application relates to the field of lampshade production, and in particular, to a clamping device for a material taking machine. Background Art

[0002] The lampshade can protect the lamp beads. At the same time, through the light scattering and filtering effects of the lampshade, the light emitted by the lamp beads becomes relatively soft, improving the user experience.

[0003] For some lamp beads with small sizes, the sizes of the lampshades adapted to them are also relatively small. During the production process of the lampshades, processes such as forming, coating, shaping, engraving, and packaging are required. Therefore, a variety of processing equipment is needed to cooperate to complete the above processes. During the above processes, the lampshades need to be sequentially passed through different types of processing equipment in an orderly manner. However, due to the low generality between the processing equipment (the effective processing quantities and sizes between the equipment are different), in order to improve the production efficiency of the lampshades, in actual applications, fixtures need to be used in cooperation with the material taking machine to complete the processing process, that is: the material taking machine transfers the lampshades completed by the previous processing equipment placed on the fixture to the next fixture, so as to realize the transformation of the spacing between several lampshades placed on the fixture, making it adapt to the processing requirements of the next processing equipment.

[0004] In actual applications, the inventor found that during the material taking process of the material taking machine for the lampshades placed on the fixture, a certain force needs to be applied to the fixture. During this process, the fixture will produce a small displacement under the influence of the force. As the number of material taking times of the material taking machine increases, the position of the fixture will change greatly, but the set material taking action of the material taking machine through programming is in a fixed state, resulting in some lampshades being unable to be accurately taken out along the current fixture or placed on the next fixture, causing a huge interference to the normal progress of the processing steps of the next processing equipment, resulting in disorderly production, and further improvement is needed. Summary of the Utility Model

[0005] In order to improve the material taking efficiency of the material taking machine, the present application provides a clamping device for a material taking machine.

[0006] The clamping device for a material taking machine provided by the present application adopts the following technical solutions:

[0007] A clamping device for a material taking machine includes a first fixing component, a second fixing component, a first fixture, and a second fixture. The first fixing component and the second fixing component are sequentially arranged on the material taking machine. The first fixture is detachably arranged on the first fixing component, and the second fixture is detachably arranged on the second fixing component. The first fixture and the second fixture are used for placing lampshades, and the material taking machine is used to sequentially transfer several lampshades placed on the first fixture to the second fixture.

[0008] By adopting the above technical solution, the operator arranges a plurality of lamp covers on the first fixture in an orderly manner, limits the installation position of the first fixture through the first fixing component, and at the same time limits the installation position of the second fixture through the second fixing component, thereby reducing the position offset of the first fixture placed on the first fixing component and the position offset of the second fixture placed on the second fixing component. Since both the first fixture and the second fixture are in a fixed state, it is beneficial to reduce the position offset of the first fixture and / or the second fixture during the process of the material taking machine taking the lamp cover, and plays a positive guiding role in reducing the probability of production disorder caused by the material taking machine clamping the lamp cover along the first fixture to the second fixture, which is beneficial to improving the material taking efficiency of the material taking machine.

[0009] Preferably, the first fixing component includes a supporting plate, and a placement area for placing the first fixture is formed on the supporting plate, and the first fixture is in transitional fit with the placement area.

[0010] By adopting the above technical solution, since the first fixture is in transitional fit with the placement area, the first fixture can be smoothly taken out along the placement area or the first fixture can be placed in the placement area, and at the same time it is beneficial to reduce the clearance between the first fixture and the placement area, effectively solving the problem of excessive position offset of the first fixture along the material taking machine.

[0011] Preferably, a plurality of limiting blocks are evenly distributed in the placement area, and a plurality of limiting grooves are evenly distributed on the surface of the first fixture facing the placement area. The number of the limiting blocks is the same as the number of the limiting grooves. When the first fixture is placed in the placement area, the plurality of limiting blocks are in one-to-one clamping fit with the plurality of limiting grooves.

[0012] By adopting the above technical solution, when the first fixture is placed in the placement area, through the cooperation of the limiting groove and the limiting block, the placement position of the first fixture along the placement area is in a relatively fixed state each time, which is beneficial to reducing the position offset when the first fixture is placed in the placement area again.

[0013] Preferably, a first micro-motion cylinder is arranged on the supporting plate, and the piston rod of the first micro-motion cylinder movably penetrates through the side wall of the supporting plate and extends into the placement area along the side wall of the supporting plate. When the first fixture is placed in the placement area, the end face of the piston rod of the first micro-motion cylinder abuts against the first fixture.

[0014] By adopting the above technical solution, when the first fixture is placed in the placement area, the working state of the first micro-motion cylinder can be controlled to make the piston rod of the first micro-motion cylinder move towards the side wall of the first fixture, so that the piston rod of the first micro-motion cylinder abuts against the side wall of the first fixture, providing a clamping force for the first fixture placed in the placement area and reducing the shaking of the first fixture along the placement area during the process of the material taking machine clamping the lamp cover.

[0015] Preferably, the second fixing assembly includes a receiving plate, the receiving plate is used to receive the second fixture, a clamping plate is slidably provided on the receiving plate, a driving member is provided on the receiving plate, and the driving member is used to drive the clamping plate to move closer to or away from the receiving plate.

[0016] By adopting the above technical solution, when the second jig needs to be placed on the receiving plate, or when the second jig needs to be taken out along the receiving plate, the driving member drives the clamping plate away from the receiving plate, thereby facilitating the placement of the second jig on the receiving plate; at the same time, when the second jig is located on the receiving plate, the driving member drives the clamping plate to move toward the receiving plate, thereby achieving a clamping effect on the second jig and reducing the position offset of the second jig when it is placed on the receiving plate.

[0017] Preferably, the accommodating plate is provided with a sliding groove along the width direction, the clamping plate is slidably disposed in the sliding groove, and the clamping plate is transitionally matched with the sliding groove.

[0018] By adopting the above technical solution, the sliding path of the clamping plate along the containing plate is limited by the sliding groove, which reduces the shaking of the clamping plate when it approaches or moves away from the containing plate. When the clamping plate is clamping the second fixture, the forces at various locations of the side wall where the second fixture and the clamping plate are in contact are relatively balanced, which reduces the probability of the second fixture popping out along the containing plate due to uneven force on the second fixture.

[0019] Preferably, a pressure sensor is provided on the clamping plate, and the pressure sensor is used to detect the force applied by the clamping plate to the second fixture.

[0020] By adopting the above technical solution, the force applied by the splint to the second fixture is detected by the pressure sensor, which effectively reduces the probability of the second fixture being deformed or damaged due to excessive force applied by the splint to the second fixture.

[0021] Preferably, a counterweight plate is provided on the surface of the second fixture abutting against the accommodating plate, and the weight of the counterweight plate is greater than the weight of the second fixture.

[0022] By adopting the above technical solution, the weight of the second fixture itself is increased by the counterweight plate, thereby reducing the probability of a situation in which the placement position of the lampshade and the second fixture becomes stuck when the material picker places the lampshade on the second fixture, but the clamping piece of the second fixture fails to be released in time, causing the material picker to drive the second fixture to change its placement along the accommodating plate.

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

[0024] 1. Since both the first fixture and the second fixture are in a fixed state, it is beneficial to reduce the position offset of the first fixture and / or the second fixture during the process of the material taking machine picking up the lamp cover, which plays a positive guiding role in reducing the probability of production disorder caused by the material taking machine clamping the lamp cover along the first fixture and moving it to the second fixture, and is beneficial to improving the material taking efficiency of the material taking machine;

[0025] 2. When the first fixture is placed in the placement area, through the cooperation of the limiting groove and the limiting block, the placement position of the first fixture along the placement area is in a relatively fixed state each time, which is beneficial to reducing the position offset when the first fixture is placed in the placement area again;

[0026] 3. By driving the clamping plate with the driving member to clamp or release the second fixture, it is beneficial to reduce the position offset of the second fixture when it is placed on the accommodating plate. Description of the Drawings

Detailed Embodiment

[0031] The following will Figures 1-3 further describe the present application in detail.

[0032] An embodiment of the present application discloses a clamping device for a material taking machine 1. Refer to Figure 1 and Figure 2, A clamping device for a material taking machine 1 includes a first fixing component 2, a second fixing component 3, a first jig 4 and a second jig 5. The first fixing component 2 and the second fixing component 3 are sequentially arranged on the material taking machine 1. The first jig 4 is detachably arranged on the first fixing component 2, and the second jig 5 is detachably arranged on the second fixing component 3. The first jig 4 and the second jig 5 are used for placing lamp shades, and the material taking machine 1 is used to sequentially transfer a plurality of lamp shades placed on the first jig 4 to the second jig 5.

[0033] Specifically, the material taking machine 1 includes a robotic arm, a controller, a clamping arm, a detection component, etc. An operator can program through the controller to control the robotic arm to carry the clamping arm along the movement path within the spatial range, use the detection component to detect the position of the lamp shade to be clamped, and at the same time control the clamping and releasing actions of the clamping arm, so as to sequentially transfer a plurality of lamp shades placed on the first jig 4 to the second jig 5, so as to realize the transformation of the spacing between a plurality of lamp shades. For the existing material taking equipment, its specific composition and working principle will not be elaborated here.

[0034] Therefore, the implementation principle of a clamping device for a material taking machine 1 in an embodiment of the present application is as follows: An operator orderly places a plurality of lamp shades on the first jig 4, limits the installation position of the first jig 4 through the first fixing component 2, and at the same time limits the installation position of the second jig 5 through the second fixing component 3, thereby reducing the position offset of the first jig 4 placed on the first fixing component 2 and the position offset of the second jig 5 placed on the second fixing component 3. Since both the first jig 4 and the second jig 5 are in a fixed state, it is beneficial to reduce the position offset of the first jig 4 and / or the second jig 5 during the material taking process of the material taking machine 1 for the lamp shades, which plays a positive guiding role in reducing the probability of production disorder caused by the material taking machine 1 clamping the lamp shades from the first jig 4 to the second jig 5, and is beneficial to improving the material taking efficiency of the material taking machine 1.

[0035] Refer to Figure 1 and Figure 2 , The first fixing component 2 includes a supporting plate 21 and a mounting frame 22. The mounting frame 22 is arranged on the material taking machine 1, the supporting plate 21 is detachably arranged on the mounting frame 22, a placement area 211 for placing the first jig 4 is opened on the supporting plate 21, and the first jig 4 is in transitional fit with the placement area 211.

[0036] Specifically, the mounting bracket 22 includes a positioning plate 221 and mounting blocks 222. The outer contour of the positioning plate 221 is arranged in a cuboid shape and is fixed to the material taking machine 1 by bolts. At the same time, there are four mounting blocks 222, which are respectively installed on the four side walls of the positioning plate 221, and bolt holes are provided on the four mounting blocks 222. The supporting plate 21 can be fixed to the four mounting blocks 222 by bolts, so as to achieve the purpose that the supporting plate 21 can be disassembled along the material taking machine 1, facilitating the replacement of supporting plates 21 of different models / sizes.

[0037] Furthermore, the placement area 211 is formed by the supporting plate 21 being recessed downward along the thickness direction. Since the first fixture 4 is in transitional fit with the placement area 211, the first fixture 4 can be smoothly taken out along the placement area 211 or the first fixture 4 can be placed in the placement area 211. At the same time, it is beneficial to reduce the clearance between the first fixture 4 and the placement area 211, effectively solving the problem of excessive position deviation of the first fixture 4 along the material taking machine 1.

[0038] At the same time, two material taking slots 12 are provided on one of the side walls of the placement area 211 along the width direction. The two material taking slots 12 are symmetrically arranged with respect to the geometric center of the width of the placement area 211. When the first fixture 4 needs to be taken out along the placement area 211, the operator can use his hand to buckle out the first fixture 4 along the placement area 211 from the material taking slot 12, and the operation is simple.

[0039] Correspondingly, referring to Figure 1 or Figure 2 and Figure 3 , a number of limiting blocks 6 are evenly distributed in the placement area 211, and a number of limiting slots 41 are evenly distributed on the surface of the first fixture 4 facing the placement area 211. The number of limiting blocks 6 is the same as the number of limiting slots 41. When the first fixture 4 is placed in the placement area 211, the number of limiting blocks 6 and the number of limiting slots 41 are in one-to-one snap-fit.

[0040] Specifically, the number of limiting blocks 6 and limiting slots 41 can be three groups, four groups, five groups, etc. In this embodiment, the number of limiting blocks 6 and limiting slots 41 are respectively set to six groups. The six groups of limiting blocks 6 are evenly distributed in the placement area 211, and the six groups of limiting blocks 6 are formed by protruding from the surface of the placement area 211 along the thickness direction. At the same time, the six groups of limiting slots 41 are evenly distributed on the first fixture 4, and the six groups of limiting slots 41 are formed by being recessed from the surface of the first fixture 4 along the thickness direction. The shapes of the six groups of limiting slots 41 are adapted to the shapes of the six groups of limiting blocks 6, and the six groups of limiting slots 41 are in transitional fit with the six groups of limiting blocks 6.

[0041] Therefore, when the first jig 4 is placed in the placement area 211, through the cooperation of the limit groove 41 and the limit block 6, the placement position of the first jig 4 along the placement area 211 is in a relatively fixed state each time, which is beneficial to reducing the position offset when the first jig 4 is placed in the placement area 211 again.

[0042] Refer to Figure 1 or Figure 2 A first micro cylinder 7 is arranged on the support plate 21. The piston rod of the first micro cylinder 7 movably penetrates through the side wall of the support plate 21 along the side wall of the support plate 21 and extends into the placement area 211. When the first jig 4 is placed in the placement area 211, the end face of the piston rod of the first micro cylinder 7 abuts against the first jig 4.

[0043] Specifically, the number of the first micro cylinders 7 can be one group or two groups, and their installation methods are the same. In this embodiment, the number of the first micro cylinders 7 is two groups. The two groups of first micro cylinders 7 are respectively installed on the support plate 21, and when the piston rods of the two groups of first micro cylinders 7 movably penetrate through the support plate 21, the piston rods of the two groups of first micro cylinders 7 first pass through the material taking groove 12 and extend into the placement area 211.

[0044] Its function is that when the first jig 4 is placed in the placement area 211, by controlling the working state of the first micro cylinder 7, the piston rod of the first micro cylinder 7 can move towards the side wall of the first jig 4, so that the piston rod of the first micro cylinder 7 abuts against the side wall of the first jig 4, providing a clamping force for the first jig 4 placed in the placement area 211 and reducing the shaking of the first jig 4 along the placement area 211 during the process of the material taking machine 1 clamping the lamp cover.

[0045] Refer to Figure 1 or Figure 2 The second fixing component 3 includes a receiving plate 31 for receiving the second jig 5. A clamping plate 311 is slidably arranged on the receiving plate 31, and a driving member 8 is arranged on the receiving plate 31 for driving the clamping plate 311 to approach or move away from the receiving plate 31.

[0046] Specifically, the receiving plate 31 is fixed on the material taking machine 1 on one side of the support plate 21. The outer contour of the receiving plate 31 is arranged in a cuboid shape. Three stop blocks 13 are arranged on the receiving plate 31. The three stop blocks 13 are respectively installed at the edges of the receiving plate 31 along the width direction and any one edge along the length direction, and a receiving area for placing the second jig 5 is formed by the three stop blocks 13.

[0047] Furthermore, the clamping plate 311 is slidably arranged at the other edge of the accommodating plate 31 along the length direction. At the same time, the driving member 8 can be a motor screw rod structure to meet the clamping requirement with higher precision. In this embodiment, the driving member 8 is arranged as a second micro-cylinder 81. The second micro-cylinder 81 is installed on the side wall of the accommodating plate 31, and the piston rod of the second micro-cylinder 81 movably penetrates through the accommodating plate 31 and is fixedly connected to the clamping plate 311.

[0048] Therefore, when the second fixture 5 needs to be placed on the accommodating plate 31 or taken out along the accommodating plate 31, the second micro-cylinder 81 drives the clamping plate 311 to move away from the accommodating plate 31, so as to facilitate placing the second fixture on the accommodating plate 31. At the same time, when the second fixture 5 is located on the accommodating plate 31, the second micro-cylinder 81 drives the clamping plate 311 to move towards the accommodating plate 31 to clamp the second fixture 5, reducing the position offset of the second fixture 5 when it is placed on the accommodating plate 31.

[0049] Correspondingly, a sliding groove 9 is formed in the accommodating plate 31 along the width direction. The clamping plate 311 is slidably arranged in the sliding groove 9, and the clamping plate 311 is in transitional fit with the sliding groove 9. The sliding path of the clamping plate 311 along the accommodating plate 31 is defined by the sliding groove 9, reducing the shaking of the clamping plate 311 when it moves closer to or away from the accommodating plate 31, so that when the clamping plate 311 clamps the second fixture 5, the forces on the side walls of the second fixture 5 in contact with the clamping plate 311 are relatively balanced at each place, reducing the probability of the second fixture 5 popping out along the accommodating plate 31 due to uneven force on the second fixture 5.

[0050] On the other hand, a pressure sensor 10 is arranged on the clamping plate 311. The pressure sensor 10 is used to detect the acting force exerted by the clamping plate 311 on the second fixture 5. When the second fixture 5 is placed in the accommodating area, the piston rod of the second micro-cylinder 81 contracts, driving the clamping plate 311 to move towards the accommodating plate 31 to clamp the second fixture 5. By detecting the acting force exerted by the clamping plate 311 on the second fixture 5 through the pressure sensor 10, it is convenient for the operator to discover abnormal situations and handle them in time, effectively reducing the probability of deformation or damage of the second fixture 5 caused by excessive acting force exerted by the clamping plate 311 on the second fixture 5.

[0051] In addition, a counterweight plate 11 is provided on the surface of the second jig 5 that abuts against the accommodation plate 31. The weight of the counterweight plate 11 is greater than that of the second jig 5. The counterweight plate 11 can be made of an aluminum plate and is fixed to the surface of the second jig 5 that abuts against the accommodation area by bolts. By adding weight to the second jig 5 itself with the counterweight plate 11, the probability of the situation where, when the lamp holder is placed on the second jig 5 by the material taking machine 1, there is a jam in the placement position of the lamp holder and the second jig 5, but the clamping member of the second jig 5 fails to release in time, resulting in a change in the placement position of the second jig 5 driven by the material taking machine 1 along the accommodation plate 31 is reduced.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
