[0051] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of methods and apparatus consistent with certain aspects of the present application, as detailed in the appended claims.

[0052] The terms "first," "second," "third," "fourth," etc. (if any) in the specification and claims of the present application and in the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential sequence. It should be understood that the numbers used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or apparatus.

[0053] At present, in the process of spraying the middle frame of a mobile phone, in order to improve the spraying efficiency, save costs and ensure the consistency of the product, the workpieces are usually stacked together in a stacking manner, and then these workpieces are sprayed at the same time. In the above method, the workpieces are separated and fixed by a jig. Generally, the workpieces and the jig need to be clamped manually, and then sent to the spraying production line for spraying. However, the above clamping method is time-consuming and labor-intensive, and the efficiency is low. In addition, manual clamping is generally carried out on a workbench, and after clamping is completed, it is necessary to use tools to transport it to the spraying production line, which can easily cause bumps and damage to the workpieces.

[0054] In response to the above-mentioned problems existing in the prior art, the present application provides a clamping device. The clamping device provided in the present application includes a device body and at least two clamping units. By arranging a first station, a second station and a third station on the device body, a plurality of jigs are placed at the first station and a plurality of workpieces are placed at the second station to prepare for clamping. By arranging two clamping units on the device body, and using one clamping unit to sequentially transfer a first preset number of jigs from the first station to the third station, while using another clamping unit to sequentially transfer a second preset number of workpieces from the second station to the third station, each workpiece is clamped by each jig to form an assembly, so that the assembly can be moved to the spraying equipment for spraying, so as to realize spraying of the frame of the workpiece and shielding the parts that do not need to be sprayed. By replacing manual clamping with two clamping units, the clamping efficiency can be improved and batch processing is facilitated.

[0055] The following specific embodiments are used to describe the technical solution of the present application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0056] Please refer to Figures 1-9 As shown, an embodiment of the present application provides a clamping device, comprising a device body 100 and at least two clamping units 200 disposed on the device body 100;

[0057] The equipment body 100 is provided with a first station 110, a second station 120 and a third station 130. The first station 110 is used to place a plurality of jigs 10, and the second station 120 is used to place a plurality of workpieces 20;

[0058] One of the two clamping units 200 is used to transfer a first preset number of fixtures 10 from the first station 110 to the third station 130 in sequence, and the other is used to transfer a second preset number of workpieces 20 from the second station 120 to the third station 130 in sequence, so as to clamp each workpiece 20 through each fixture 10 to form an assembly.

[0059] The fixture 10 in this embodiment is used to install or fix the workpiece 20, while exposing the frame of the workpiece 20 to facilitate spraying, while shielding the front and back sides of the workpiece 20 that do not require spraying. The fixture 10 is generally a plate-shaped structure.

[0060] The workpiece 20 in this embodiment can be the middle frame of a mobile phone, or other plate-shaped, frame-shaped products that need to be sprayed. After the frames of the workpiece 20 are sprayed separately, the next production process can be carried out.

[0061] Specifically, such as Figure 2 As shown, the jig 10 has two opposite sides, one of which is used to cooperate with the front of the workpiece 20, and the other is used to cooperate with the back of the workpiece 20. The workpiece 20 can be fixed on the jig 10 by means of snap-on, plug-in, etc., which is convenient for positioning, splitting, etc. For example, a plurality of magnetic suction parts are provided on the jig 10. When the workpiece 20 and the jig 10 are fitted together, the two can be sucked together to facilitate subsequent splitting. It should be noted that the specific shape, size, number of holes and other structures of the jig 10 need to be determined according to the workpiece 20, and can satisfy the requirements of exposing the frame of the workpiece 20 while covering the front and back of the workpiece 20.

[0062] The equipment body 100 in this embodiment is used to provide an installation base, which can be a frame-shaped, shell-shaped or other structure. The equipment body 100 is provided with at least a first workstation 110, a second workstation 120 and a third workstation 130. The first workstation 110 and the second workstation 120 can be arranged side by side and at intervals, and the third workstation 130 can be arranged between the first workstation 110 and the second workstation 120.

[0063] The first station 110 is used to place multiple jigs 10, which can be transported sequentially by a conveyor or placed one by one manually. The second station 120 is used to place multiple workpieces 20, which can be transported sequentially by a conveyor or placed one by one manually, both in parallel. The third station 130 is used to stack the assembled assembly formed by clamping multiple jigs 10 and multiple workpieces 20.

[0064] The two clamping units 200 in this embodiment are used to transport each fixture 10 and each workpiece 20 respectively. They can be a clamping and moving mechanism, a robot, etc., and any mechanism that can take and place the fixture 10 or the workpiece 20 and move it from one position to another.

[0065] Specifically, if Figure 1 、 Figure 2As shown, one clamping unit 200 first takes a jig 10 from the first station 110 and transfers it to the third station 130, and then another clamping unit 200 takes a workpiece 20 from the second station 120 and transfers it to the third station 130, stacking it on the jig 10, and then transfers another jig 10 to stack it on the workpiece 20..., and repeats the transfer operation alternately until the first preset number of jigs 10 and the second preset number of workpieces 20 are all transferred to the third station 130, so that each jig 10 and each workpiece 20 are placed at intervals from each other and form an assembly, so that the front and back of each workpiece 20 are blocked by each jig 10, leaving only the frame exposed, so that the assembly is conveniently moved to the spraying equipment for the next spraying operation, and after the spraying process, each jig 10 and each workpiece 20 can be disassembled.

[0066] It should be noted that the first preset number and the second preset number can be any number, such as 10 for the first preset number and 9 for the second preset number, depending on actual needs. However, the first preset number must be one more than the second preset number to ensure that all jigs 10 can separate all workpieces 20 and cover the front and back surfaces. In addition, the jigs 10 and workpieces 20 described above are stacked vertically. Of course, the jigs 10 and workpieces 20 can also be stacked horizontally, depending on actual placement needs.

[0067] Compared to the manual clamping of the fixture 10 and the workpiece 20, the clamping device in the embodiment of the present application uses two clamping units 200 to replace manual clamping, which can improve clamping efficiency and facilitate batch processing. In addition, clamping through mechanical equipment can avoid or reduce damage caused by manual clamping, thereby ensuring clamping quality.

[0068] Therefore, the clamping device provided in the embodiment of the present application includes an equipment body 100 and at least two clamping units 200. By setting a first workstation 110, a second workstation 120 and a third workstation 130 on the equipment body 100, multiple jigs 10 are placed at the first workstation 110, and multiple workpieces 20 are placed at the second workstation 120 to prepare for clamping. By setting two clamping units 200 on the equipment body 100, and using one clamping unit 200 to transfer a first preset number of fixtures 10 from the first station 110 to the third station 130 in sequence, and using another clamping unit 200 to transfer a second preset number of workpieces 20 from the second station 120 to the third station 130 in sequence, each workpiece 20 is clamped by each fixture 10 to form an assembly, which is convenient for moving the assembly to the spraying equipment for spraying, so as to achieve spraying of the frame of the workpiece 20 and shielding the parts that do not need to be sprayed. By using two clamping units 200 to replace manual clamping, the clamping efficiency can be improved and batch processing is convenient.

[0069] In one possible design, the clamping unit 200 includes a pick-and-place mechanism 210 and a transfer mechanism 220 , and the pick-and-place mechanism 210 is used to pick up and place the fixture 10 or the workpiece 20 .

[0070] The transfer mechanism 220 is connected to the pick-and-place mechanism 210 , and the transfer mechanism 220 is used to transfer the pick-and-place mechanism 210 between the first workstation 110 and the third workstation 130 or between the second workstation 120 and the third workstation 130 .

[0071] Specifically, if Figure 3 、 Figure 4 As shown, the pick-and-place mechanism 210 is used to pick up and place the fixture 10 or the workpiece 20, which can be a suction mechanism or a clamping mechanism. The transfer mechanism 220 is used to move the pick-and-place mechanism 210 from one position to another position. It can be a moving mechanism or a manipulator with at least two moving directions. The transfer mechanism 220 is set on the equipment body 100, and the pick-and-place mechanism 210 is set at the moving end of the transfer mechanism 220. The trajectory of the pick-and-place mechanism 210 driven by the transfer mechanism 220 can be along Figure 4 As shown by the dotted arrow in , the transfer of the fixture 10 or the workpiece 20 is achieved.

[0072] Furthermore, in this embodiment, the pick-and-place mechanism 210 includes a mounting seat 211 and a pick-and-place component 212 . The mounting seat 211 is connected to the transfer mechanism 220 , and the pick-and-place component 212 is disposed on the mounting seat 211 .

[0073] When the transfer mechanism 220 moves the pick-and-place component 212 to the first preset position on the first station 110 , the pick-and-place component 212 absorbs the jig 10 ; when the transfer mechanism 220 moves the pick-and-place component 212 to the third preset position on the third station 130 , the pick-and-place component 212 releases the jig 10 .

[0074] Alternatively, when the transfer mechanism 220 moves the pick-and-place component 212 to the second preset position on the second workstation 120 , the pick-and-place component 212 absorbs the workpiece 20 ; when the transfer mechanism 220 moves the pick-and-place component 212 to the fourth preset position on the third workstation 130 , the pick-and-place component 212 releases the workpiece 20 .

[0075] Specifically, if Figure 3 As shown, the mounting base 211 is used to provide a mounting base and can be in the form of a block, shell, frame, or other structure. The mounting base 211 is disposed at the movable end of the transfer mechanism 220. The pick-and-place assembly 212 can be a suction cup, a clamp, or the like, and is disposed on the mounting base 211, with the pick-and-place end of the pick-and-place assembly 212 facing toward the first station 110, the second station 120, or the third station 130.

[0076] In one example, when transferring the jig 10, the transfer mechanism 220 moves the pick-and-place component 212 to the first preset position on the first workstation 110, and the pick-and-place component 212 absorbs the jig 10. Afterwards, when the transfer mechanism 220 moves the pick-and-place component 212 to the third preset position on the third workstation 130, the pick-and-place component 212 releases the jig 10 to place the jig 10.

[0077] It should be noted that the first preset position can be a fixed position, and the third preset position gradually changes as the number of jigs 10 and workpieces 20 stacked increases, and the extent of the change depends on the thickness of the jigs 10 and workpieces 20.

[0078] In another example, when transferring the workpiece 20, the transfer mechanism 220 moves the pick-and-place component 212 to the second preset position on the second workstation 120, and the pick-and-place component 212 absorbs the workpiece 20. Afterwards, when the transfer mechanism 220 moves the pick-and-place component 212 to the fourth preset position on the third workstation 130, the pick-and-place component 212 releases the workpiece 20 to place the workpiece 20.

[0079] It should be noted that the second preset position can be a fixed position, and the fourth preset position gradually changes as the number of jigs 10 and workpieces 20 stacked increases, and the extent of the change depends on the thickness of the jigs 10 and workpieces 20.

[0080] Furthermore, in this embodiment, the pick-and-place mechanism 210 further includes a positioning assembly 213 and a driving member 214 . The positioning assembly 213 is disposed on the mounting seat 211 , and the pick-and-place assembly 212 is connected to the positioning assembly 213 via the driving member 214 .

[0081] When the pick-and-place assembly 212 is located at the first preset position, the positioning assembly 213 abuts against the fixture 10 to position it, and the driving member 214 drives the pick-and-place assembly 212 to move along the first direction to absorb the fixture 10 .

[0082] Alternatively, when the pick-and-place assembly 212 is located at the second preset position, the positioning assembly 213 abuts against the workpiece 20 to position it, and the driving member 214 drives the pick-and-place assembly 212 to move along the second direction to absorb the workpiece 20 .

[0083] Specifically, if Figure 5 、 Figure 6 As shown, the positioning component 213 is used for the pick-and-place mechanism 210 to perform secondary positioning on the jig 10 or the workpiece 20 when the jig 10 or the workpiece 20 is sucked tightly, to ensure that both are accurately placed in the preset position. The positioning component 213 can be a block-shaped, frame-shaped, shell-shaped or other structures. The positioning component 213 has at least a positioning surface on one side facing the first station 110 or the second station 120 or the third station 130. When the positioning component 213 abuts against the jig 10 or the workpiece 20, positioning is performed through the positioning surface.

[0084] The driving member 214 is used to drive the pick-and-place assembly 212 to move so as to be able to pick up the fixture 10 or the workpiece 20 . The driving member 214 can be a telescopic member, a cylinder, an oil cylinder, etc. The pick-and-place assembly 212 is connected to the positioning assembly 213 through the driving member 214 .

[0085] In one example, when the fixture 10 is positioned for the second time, the pick-and-place assembly 212 is located at the first preset position, the positioning assembly 213 abuts against the fixture 10 and positions it, and the driving member 214 drives the pick-and-place assembly 212 to move along the first direction, such as along Figure 5 The middle Z axis moves to move the pick-and-place assembly 212 and tightly adhere to the fixture 10 . After the pick-and-place assembly 212 puts down the fixture 10 , the driving member 214 drives the pick-and-place assembly 212 back to the starting position.

[0086] In another example, when the workpiece 20 is positioned for the second time, when the pick-and-place assembly 212 is located at the second preset position, the positioning assembly 213 abuts against the workpiece 20 and positions it, and the driving member 214 drives the pick-and-place assembly 212 to move along the second direction, such as along Figure 5 The middle Z axis moves to move the pick-and-place assembly 212 and tightly clamp the workpiece 20 . After the pick-and-place assembly 212 puts down the workpiece 20 , the driving member 214 drives the pick-and-place assembly 212 back to the starting position.

[0087] Furthermore, in this embodiment, an elastic component 215 is further included. The positioning component 213 moves relative to the mounting base 211 and is connected to the mounting base 211 through the elastic component 215 .

[0088] When the positioning component 213 is pressed against the fixture 10 or the workpiece 20 , the elastic component 215 generates a preset deformation to provide a buffer.

[0089] Specifically, combined Figure 4 、 Figure 5 、 Figure 6 As shown, the elastic component 215 is used to elastically press the pick-and-place component 212 when placing the fixture 10 or the workpiece 20. That is, the elastic component 215 is used for elastic buffering to avoid damage to the fixture 10 or the workpiece 20 due to rigid compression. The elastic component 215 can be a guide rod and a spring component, the spring is sleeved on the guide rod, and the positioning component 213 can be slidably connected to the mounting seat 211 through a guide rail or a guide structure, such as along Figure 5 The positioning assembly 213 is connected to the mounting seat 211 through a guide rod and a spring so that the elastic assembly 215 exerts an elastic force on the positioning assembly 213 along the Z axis. Figure 5 The elastic force in the opposite direction of the Z axis.

[0090] With this arrangement, when positioning assembly 213 is pressed against jig 10 or workpiece 20, it elastically compresses against the underlying workpiece 20 or jig 10, ensuring a tight fit while also preventing damage from rigid compression. The specific structure and number of elastic assembly 215 can be determined based on actual needs and are not specifically limited in this embodiment.

[0091] Furthermore, in this embodiment, the positioning component 213 has a positioning portion 2131 on the side facing the first workstation 110 or the second workstation 120. The positioning portion 2131 is used to cooperate with the jig 10 or the workpiece 20 for positioning, and the positioning portion 2131 is also used to guide and adjust the jig 10 or the workpiece 20.

[0092] Specifically, combined Figure 5 、 Figure 7 As shown, the positioning portion 2131 is used to cooperate with the jig 10 or the workpiece 20 to better perform secondary positioning of the jig 10 or the workpiece 20. The positioning portion 2131 can be a positioning column, a positioning block, a positioning protrusion, a positioning groove, etc., depending on the specific location on the jig 10 or the workpiece 20, and is not specifically limited in this embodiment.

[0109] The specific types, quantities, and locations of the detection components and controllers can be determined according to actual needs and are not specifically limited in this embodiment.

[0110] In some embodiments, the clamping unit 200 further includes a conveying mechanism 230 , which is used to convey each fixture 10 or each workpiece 20 in sequence.

[0111] That is, one side of the conveying mechanism 230 is located at the first workstation 110 and is used to convey the jigs 10 in sequence.

[0112] Alternatively, one side of the conveying mechanism 230 is located at the second workstation 120 and is used to convey each workpiece 20 in sequence.

[0113] With this arrangement, the conveying mechanism 230 can sequentially convey the jig 10 to the first station 110 , or sequentially convey the workpiece 20 to the second station 120 , thereby ensuring that the transfer of the jig 10 or the workpiece 20 is carried out in an orderly manner.

[0114] Furthermore, in this embodiment, the conveying mechanism 230 includes a first conveying component 231 and a limiting component 232 provided on the first conveying component 231 . The limiting component 232 is used to limit the position of the fixture 10 or the workpiece 20 .

[0115] The first conveying assembly 231 is used to convey the jig 10 , and the limiting assembly 232 is located at the first workstation 110 . When the first conveying assembly 231 conveys the jig 10 to the first preset position, the limiting assembly 232 limits the jig 10 at the current position.

[0116] Alternatively, the first conveying component 231 is used to convey the workpiece 20, and the limiting component 232 is located at the second workstation 120. When the first conveying component 231 conveys the workpiece 20 to the second preset position, the limiting component 232 limits the workpiece 20 at the current position.

[0117] Specifically, if Figure 3 As shown, the first conveying assembly 231 is used to convey the jig 10 or the workpiece 20, which can be a belt conveyor, a plate conveyor, etc. For example, the first conveying assembly 231 can include a frame, a conveyor belt and a plurality of conveyor rollers, and the conveyor belt is mounted on the frame through the plurality of conveyor rollers. The limiting assembly 232 is used to limit the jig 10 or the workpiece 20, which can be a limiting plate, a limiting block, etc., so that when the jig 10 or the workpiece 20 contacts the limiting assembly 232, the lateral position can be adjusted, such as adjusting the position along the Figure 3 The position along the X axis.

[0118] In one example, when the first conveying component 231 is used to convey the jig 10, one side of the first conveying component 231 is located at the first workstation 110, and the limiting component 232 is located at the first workstation 110. When the first conveying component 231 conveys the jig 10 to the first preset position, the limiting component 232 limits the jig 10 at the current position so that the pick-and-place mechanism 210 can accurately absorb the jig 10.

[0119] In another example, when the first conveying component 231 is used to convey the workpiece 20, one side of the first conveying component 231 is located at the second workstation 120, and the limiting component 232 is located at the second workstation 120. When the first conveying component 231 conveys the workpiece 20 to the second preset position, the limiting component 232 limits the workpiece 20 at the current position so that the pick-up and placement mechanism 210 can accurately absorb the workpiece 20.

[0120] In addition, the first conveying assembly 231 may be provided with a foolproofing device and a detection sensor. The foolproofing device can ensure the correct placement order of the jig 10 or workpiece 20, and the detection sensor can detect the presence of the jig 10 or workpiece 20 at the current location. The specific structure of the first conveying assembly 231 and the limit assembly 232 can be determined according to actual needs and is not excessively limited in this embodiment.

[0121] In some embodiments, a transfer unit 300 is further included on the device body 100 , and the transfer unit 300 includes a receiving component 310 .

[0122] The receiving assembly 310 is located at the third station 130 and is used to receive the assembly.

[0123] Specifically, combined Figure 3 、 Figure 8 As shown, the receiving assembly 310 is used to receive the assembly. It can be a plate-shaped or block-shaped structure, capable of receiving the jig 10 and placing it stably. The receiving assembly 310 can be equipped with a magnetic component to secure the jig 10, and an adjustment block can also be provided to meet the needs of adjusting the receiving position. In this way, after clamping is completed, the operator can remove the assembly from the receiving assembly 310, making it easier to operate.

[0124] Furthermore, in this embodiment, the transfer unit 300 also includes a second lifting component 320 and a second conveying component 330. The receiving component 310 is connected to the equipment body 100 through the second lifting component 320. One side of the second conveying component 330 is located at the third workstation 130 for conveying assemblies.

[0125] When the two clamping units 200 respectively transfer the first preset number of fixtures 10 and the second preset number of workpieces 20 to the third workstation 130, the second lifting component 320 drives the receiving component 310 to descend to the third preset height to place the assembly on the second lifting component 320, and the second conveying component 330 conveys the assembly to the next workstation.

[0126] Specifically, combined Figure 3 、 Figure 8 、 Figure 9 As shown, the second lifting assembly 320 is used to drive the receiving assembly 310 to rise and fall, and it can be a component such as a cylinder or an oil cylinder. The receiving assembly 310 is connected to the equipment body 100 through the second lifting assembly 320. The second conveying assembly 330 is used to convey the assembly, and it can be a belt conveyor, a plate conveyor, etc. For example, the first conveying assembly 231 can include a frame, a conveyor belt, and a plurality of conveyor rollers. The conveyor belt is mounted on the frame through the plurality of conveyor rollers.

[0127] For example, when the two clamping units 200 respectively transfer the first preset number of fixtures 10 and the second preset number of workpieces 20 to the third workstation 130, the second lifting component 320 drives the receiving component 310 to descend to the third preset height to place the assembly on the second lifting component 320, the receiving component 310 is separated from the assembly, the second conveying component 330 conveys the assembly to the next workstation, and then the second lifting component 320 drives the receiving component 310 to rise back to its original position.

[0128] In this way, the production requirements of the assembly line can be met, and the degree of automation is high. Among them, the third preset height can ensure that when the second lifting assembly 320 drives the receiving assembly 310 to descend to contact the second conveying assembly 330, the receiving assembly 310 and the assembly are separated. It can be determined according to actual needs and is not specifically limited in this embodiment.

[0129] Furthermore, in this embodiment, a side of the second conveying component 330 facing the third workstation 130 has an escape opening 331 , and the escape opening 331 is used to receive the component 310 for lifting and lowering.

[0130] Specifically, combined Figure 4 、 Figure 9 As shown, the width of the avoidance opening 331 is slightly larger than the width of the receiving assembly 310, and the width of the receiving assembly 310 should be smaller than the width of the jig 10, to ensure that when the jig 10 moves up with the receiving assembly 310, the two side portions of the jig 10 in the width direction are suspended in the air, and when the jig 10 moves up with the receiving assembly 310, the two side portions of the jig 10 in the width direction are placed on both sides of the second conveying assembly 330, thereby achieving smooth transfer of the jig 10 between the receiving assembly 310 and the second conveying assembly 330.

[0131] The width and size of the avoidance opening 331 are determined according to the second conveying assembly 330 and are not specifically limited in this embodiment. In addition, the width of the second conveying assembly 330 can also be adjusted to accommodate assemblies of different widths, thus having a wider range of applications.
