[0063] The present invention will be further described below with reference to the accompanying drawings.

[0064] Remote controls are essential accessories for home appliances such as air conditioners and televisions. They control the on / off status and other functions of these appliances by generating remote control signals. In the production and assembly of remote controls, the faceplate assembly process involves using a mechanical clamping device to grip and press the faceplate before assembling it. However, this process is inefficient, and the faceplate may not be properly positioned after being gripped, affecting both the assembly quality and efficiency of the remote control.

[0065] Example 1

[0066] like Figure 1 , Figure 5 As shown, in order to solve the above-mentioned technical problems, this utility model embodiment provides a clamping structure, including a frame 10, a clamping device, and a positioning device 40; the clamping device is disposed on the frame 10, and the clamping device is configured to clamp the workpiece and adjust the workpiece from a vertical state to a horizontal state; the positioning device 40 is disposed on the frame 10, and the positioning device 40 includes a positioning station 430, and the positioning device 40 is configured to horizontally transfer the workpiece on the clamping device to the positioning station 430 and position the workpiece.

[0067] As can be seen from the above, the clamping device clamps the workpiece and adjusts it to a horizontal position, facilitating the subsequent receiving and transfer of the workpiece by the positioning device. By setting the positioning device 40 to calibrate and adjust the position of the workpiece on the positioning station 430, the positioned workpiece can be placed in the target position, thereby ensuring that the workpiece is placed in place, improving the assembly quality and efficiency of the product. Compared with the existing shell assembly process, this utility model improves production efficiency, optimizes product quality, and provides a foundation for the precise assembly of the product.

[0068] It should be noted that the workpiece includes, but is not limited to, the remote control faceplate.

[0069] It should also be noted that the clamping structure also includes a turnover box located below the first clamping component 20. The turnover box contains multiple workpieces, and all the workpieces in the turnover box are in a vertical position. The first clamping component 20 clamps the vertical workpieces from the turnover box.

[0070] Example 2

[0071] like Figure 1 , Figure 5 As shown, the clamping structure includes a frame 10, a clamping device, and a positioning device 40. The clamping device is mounted on the frame 10 and is configured to clamp the workpiece and adjust it from a vertical to a horizontal position. The positioning device 40 is mounted on the frame 10 and includes a positioning station 430. The positioning device 40 is configured to horizontally transfer the workpiece from the clamping device to the positioning station 430 and position the workpiece.

[0072] As can be seen above, the clamping device grips the workpiece and adjusts it to a horizontal position, facilitating the subsequent receiving and transfer of the workpiece by the positioning device. By setting the positioning device 40 to calibrate and adjust the position of the workpiece on the positioning station 430, the positioned workpiece can be placed in the target position, thereby ensuring that the workpiece is placed in place, improving the assembly quality and efficiency of the product. Compared with the existing shell assembly process, this improves production efficiency, optimizes product quality, and provides a foundation for the precise assembly of the product.

[0073] It should be noted that the workpiece includes, but is not limited to, the remote control faceplate.

[0074] It should also be noted that the clamping structure also includes a turnover box located below the first clamping component 20. The turnover box contains multiple workpieces, and all the workpieces in the turnover box are in a vertical position. The first clamping component 20 clamps the vertical workpieces from the turnover box.

[0075] In some embodiments, the clamping device includes a plurality of first clamping components 20 and a plurality of second clamping components 30; the plurality of first clamping components 20 are movably disposed on the frame 10 to clamp and transfer workpieces; the plurality of second clamping components 30 are disposed on the frame 10 and located on the moving path of the first clamping components 20, and the second clamping components 30 are configured to receive the workpieces transferred by the first clamping components 20 and adjust the workpieces from a vertical state to a horizontal state.

[0076] By setting up multiple first clamping components 20 and multiple second clamping components 30 to clamp multiple workpieces simultaneously and transferring the clamped workpieces to the positioning station 430 for positioning, preparation is made for the assembly of the remote control. This achieves clamping and positioning of multiple workpieces at one time, thereby shortening the process cycle and improving production efficiency.

[0077] It should also be noted that, such as Figure 1 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction. Furthermore, the workpiece can be vertical (parallel to the height direction) or horizontal (parallel to the length direction).

[0078] It should also be noted that the number of the first clamping component 20, the second clamping component 30, and the positioning device 40 can be set according to specific needs. Specifically, the number of the first clamping component 20 and the second clamping component 30 can be equal, the number of positioning stations 430 can be more than the number of the first clamping component 20, and the second clamping component 30 can clamp the workpiece multiple times and transfer it to the positioning station 430 to ensure that each positioning station 430 is equipped with a workpiece, so that the positioning device 40 can position multiple workpieces at the same time and complete the positioning in one go. For example, the number of the first clamping component 20 and the second clamping component 30 can both be two, and the number of positioning stations 430 can be four.

[0079] In some embodiments, the clamping structure further includes a first translation mechanism disposed on the frame 10, the first translation mechanism being configured to drive the first clamping assembly 20 to move along the length direction and height direction of the frame 10.

[0080] The first translation mechanism drives the first clamping assembly 20 to move, providing a structural basis for the first clamping assembly 20 to clamp the workpiece from the turnover box and transfer the clamped workpiece to the second clamping assembly 30.

[0081] It should be noted that the specific structure and working principle of the first translation mechanism are existing technologies. For example, the first translation mechanism is a lead screw linear module or a gear and rack linear module, which will not be described in detail in this application.

[0082] like Figure 2 As shown, in some embodiments, a plurality of first gripping assemblies 20 are arranged at intervals along the width direction of the frame 10. Each first gripping assembly 20 includes a first base 210, a first gripping cylinder 220, two first gripping jaws 230, and a first flexible contact member 240. The first base 210 is disposed on a first translation mechanism. The first gripping cylinder 220 is disposed on the first base 210 and includes two first slides 250, which move in opposite directions. The two first gripping jaws 230 correspond one-to-one with the two first slides 250 and are disposed on the corresponding first slides 250 to clamp or release the workpiece. The first flexible contact member 240 is disposed at the end of the first gripping jaw 230 away from the first slide 250 to contact the workpiece.

[0083] The first clamping assembly 20 clamps the vertically positioned workpiece. The first clamping cylinder 220 drives two first slides 250 to move in opposite directions, and the first clamping jaws 230 move with the corresponding first slides 250, thereby clamping or releasing the workpiece. By setting a first flexible contact member 240 to abut against the workpiece during clamping, a flexible pressing effect is achieved, reducing damage and scratches caused by rigid pressing, thus further improving the product quality pass rate. Simultaneously, the first flexible contact member 240 can evenly distribute pressure during clamping, avoiding the uneven pressure phenomenon of traditional methods, improving product assembly quality and efficiency.

[0084] It should be noted that the first flexible contact 240 is a rubber contact.

[0085] It should also be noted that, such as Figure 2 As shown, the two first slides 250 move along the width direction and in opposite directions. The first clamping assembly 20 also includes two transition blocks 260, which correspond one-to-one with the two first slides 250. The transition blocks 260 are provided with a plurality of transition threaded holes arranged at intervals along the height direction, and the first clamping jaws 230 are provided with fixed threaded holes. The user can select the appropriate transition threaded holes to connect with the fixed threaded holes according to the installation needs, and use screws to fix the transition blocks 260 and the first clamping jaws 230, thereby adjusting the installation height of the first clamping jaws 230 and thus adjusting the effective clamping length.

[0086] It should also be noted that the first gripping cylinder 220 includes, but is not limited to, the finger slide cylinder.

[0087] like Figure 1 , Figure 3 As shown, in some embodiments, a plurality of second gripping components 30 are arranged at intervals along the width direction, and each of the plurality of second gripping components 30 corresponds one-to-one with a plurality of first gripping components 20. Each second gripping component 30 includes a rotary drive 310, a second base 320, a second gripping cylinder 330, two second gripping jaws 340, and a second flexible contact member 360. The rotary drive 310 is disposed on the frame 10. The second base 320 is disposed on the rotating shaft of the rotary drive 310. The second gripping cylinder 330 is disposed on the second base 320 and includes two second slides 350, the two slides 350 moving in opposite directions. The two second gripping jaws 340 correspond one-to-one with the two second slides 350, and the second gripping jaws 340 are disposed on the corresponding second slides 350 to clamp or release the workpiece. The second flexible contact member 360 is disposed at the end of the second gripping jaw 340 away from the second slide 350 to contact the workpiece.

[0088] The second clamping cylinder 330 drives the two second slides 350 to move in opposite directions, and the second clamping jaws 340 move with the corresponding second slides 350, thereby clamping or releasing the workpiece. After the second clamping jaws 340 clamp the workpiece, the rotary drive 310 drives the second base 320 to rotate, and the workpiece rotates with the second base 320, thereby changing the vertical workpiece to a horizontal position, making it easier for the clamping part 410 to clamp the workpiece. By setting the second flexible contact member 360 to abut against the workpiece when clamping, it plays a role in flexible pressing, realizing flexible clamping and reducing the phenomenon of pressure damage and scratches caused by hard pressing, thereby further improving the product quality pass rate. At the same time, the second flexible contact member 360 can evenly distribute pressure when clamping the workpiece, avoiding the uneven pressure phenomenon of traditional mode, improving the assembly quality and efficiency of the product.

[0089] It should be noted that the second flexible contact 360 is a rubber contact; the second gripping cylinder 330 includes, but is not limited to, a finger slide cylinder; and the rotary drive 310 includes, but is not limited to, a motor.

[0090] It should also be noted that the two second slides 350 move along the width direction and in opposite directions.

[0091] It should also be noted that the second clamping assembly 30 can adjust the contact length with the workpiece by adjusting the second clamping cylinder 330 and replacing the second flexible contact 360.

[0092] Example 3

[0093] like Figure 1 , Figure 5 As shown, the clamping structure includes a frame 10, a clamping device, and a positioning device 40. The clamping device is mounted on the frame 10 and is configured to clamp the workpiece and adjust it from a vertical to a horizontal position. The positioning device 40 is mounted on the frame 10 and includes a positioning station 430. The positioning device 40 is configured to horizontally transfer the workpiece from the clamping device to the positioning station 430 and position the workpiece.

[0094] As can be seen from the above, the clamping device clamps the workpiece and adjusts it to a horizontal position, facilitating the subsequent receiving and transfer of the workpiece by the positioning device. By setting the positioning device 40 to calibrate and adjust the position of the workpiece on the positioning station 430, the positioned workpiece can be placed in the target position, thereby ensuring that the workpiece is placed in place, improving the assembly quality and efficiency of the product. Compared with the existing shell assembly process, this utility model improves production efficiency, optimizes product quality, and provides a foundation for the precise assembly of the product.

[0095] It should be noted that the workpiece includes, but is not limited to, the remote control faceplate.

[0096] It should also be noted that the clamping structure also includes a turnover box located below the first clamping component 20. The turnover box contains multiple workpieces, and all the workpieces in the turnover box are in a vertical position. The first clamping component 20 clamps the vertical workpieces from the turnover box.

[0097] In some embodiments, the clamping device includes a plurality of first clamping components 20 and a plurality of second clamping components 30; the plurality of first clamping components 20 are movably disposed on the frame 10 to clamp and transfer workpieces; the plurality of second clamping components 30 are disposed on the frame 10 and located on the moving path of the first clamping components 20, and the second clamping components 30 are configured to receive the workpieces transferred by the first clamping components 20 and adjust the workpieces from a vertical state to a horizontal state.

[0098] By setting up multiple first clamping components 20 and multiple second clamping components 30 to clamp multiple workpieces simultaneously and transferring the clamped workpieces to the positioning station 430 for positioning, preparation is made for the assembly of the remote control. This achieves clamping and positioning of multiple workpieces at one time, thereby shortening the process cycle and improving production efficiency.

[0099] It should also be noted that, such as Figure 1 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction. Furthermore, the workpiece can be vertical (parallel to the height direction) or horizontal (parallel to the length direction).

[0100] It should also be noted that the number of the first clamping component 20, the second clamping component 30, and the positioning device 40 can be set according to specific needs. Specifically, the number of the first clamping component 20 and the second clamping component 30 can be equal, the number of positioning stations 430 can be more than the number of the first clamping component 20, and the second clamping component 30 can clamp the workpiece multiple times and transfer it to the positioning station 430 to ensure that each positioning station 430 is equipped with a workpiece, so that the positioning device 40 can position multiple workpieces at the same time and complete the positioning in one go. For example, the number of the first clamping component 20 and the second clamping component 30 can both be two, and the number of positioning stations 430 can be four.

[0101] In some embodiments, the clamping structure further includes a first translation mechanism disposed on the frame 10, the first translation mechanism being configured to drive the first clamping assembly 20 to move along the length direction and height direction of the frame 10.

[0102] The first translation mechanism drives the first clamping assembly 20 to move, providing a structural basis for the first clamping assembly 20 to clamp the workpiece from the turnover box and transfer the clamped workpiece to the second clamping assembly 30.

[0103] It should be noted that the specific structure and working principle of the first translation mechanism are existing technologies. For example, the first translation mechanism is a lead screw linear module or a gear and rack linear module, which will not be described in detail in this application.

[0104] like Figure 2 As shown, in some embodiments, a plurality of first gripping assemblies 20 are arranged at intervals along the width direction of the frame 10. Each first gripping assembly 20 includes a first base 210, a first gripping cylinder 220, two first gripping jaws 230, and a first flexible contact member 240. The first base 210 is disposed on a first translation mechanism. The first gripping cylinder 220 is disposed on the first base 210 and includes two first slides 250, which move in opposite directions. The two first gripping jaws 230 correspond one-to-one with the two first slides 250 and are disposed on the corresponding first slides 250 to clamp or release the workpiece. The first flexible contact member 240 is disposed at the end of the first gripping jaw 230 away from the first slide 250 to contact the workpiece.

[0105] The first clamping assembly 20 clamps the vertically positioned workpiece. The first clamping cylinder 220 drives two first slides 250 to move in opposite directions, and the first clamping jaws 230 move with the corresponding first slides 250, thereby clamping or releasing the workpiece. By setting a first flexible contact member 240 to abut against the workpiece during clamping, a flexible pressing effect is achieved, reducing damage and scratches caused by rigid pressing, thus further improving the product quality pass rate. Simultaneously, the first flexible contact member 240 can evenly distribute pressure during clamping, avoiding the uneven pressure phenomenon of traditional methods, improving product assembly quality and efficiency.

[0106] It should be noted that the first flexible contact 240 is a rubber contact.

[0107] It should also be noted that, such as Figure 2 As shown, the two first slides 250 move along the width direction and in opposite directions. The first clamping assembly 20 also includes two transition blocks 260, which correspond one-to-one with the two first slides 250. The transition blocks 260 are provided with a plurality of transition threaded holes arranged at intervals along the height direction, and the first clamping jaws 230 are provided with fixed threaded holes. The user can select the appropriate transition threaded holes to connect with the fixed threaded holes according to the installation needs, and use screws to fix the transition blocks 260 and the first clamping jaws 230, thereby adjusting the installation height of the first clamping jaws 230 and thus adjusting the effective clamping length.

[0108] It should also be noted that the first gripping cylinder 220 includes, but is not limited to, the finger slide cylinder.

[0109] like Figure 1 , Figure 3 As shown, in some embodiments, a plurality of second gripping components 30 are arranged at intervals along the width direction, and each of the plurality of second gripping components 30 corresponds one-to-one with a plurality of first gripping components 20. Each second gripping component 30 includes a rotary drive 310, a second base 320, a second gripping cylinder 330, two second gripping jaws 340, and a second flexible contact member 360.

The second gripping cylinder 330 is disposed on the second base 320 and includes two second slides 350, the two slides 350 moving in opposite directions. The two second gripping jaws 340 correspond one-to-one with the two second slides 350, and the second gripping jaws 340 are disposed on the corresponding second slides 350 to clamp or release the workpiece. The second flexible contact member 360 is disposed at the end of the second gripping jaw 340 away from the second slide 350 to contact the workpiece.

[0110] The second clamping cylinder 330 drives the two second slides 350 to move in opposite directions, and the second clamping jaws 340 move with the corresponding second slides 350, thereby clamping or releasing the workpiece. After the second clamping jaws 340 clamp the workpiece, the rotary drive 310 drives the second base 320 to rotate, and the workpiece rotates with the second base 320, thereby changing the vertical workpiece to a horizontal position, making it easier for the clamping part 410 to clamp the workpiece. By setting the second flexible contact member 360 to abut against the workpiece when clamping, it plays a role in flexible pressing, realizing flexible clamping and reducing the phenomenon of pressure damage and scratches caused by hard pressing, thereby further improving the product quality pass rate. At the same time, the second flexible contact member 360 can evenly distribute pressure when clamping the workpiece, avoiding the uneven pressure phenomenon of traditional mode, improving the assembly quality and efficiency of the product.

[0111] It should be noted that the second flexible contact 360 is a rubber contact; the second gripping cylinder 330 includes, but is not limited to, a finger slide cylinder; and the rotary drive 310 includes, but is not limited to, a motor.

[0112] It should also be noted that the two second slides 350 move along the width direction and in opposite directions.

[0113] It should also be noted that the second clamping assembly 30 can adjust the contact length with the workpiece by adjusting the second clamping cylinder 330 and replacing the second flexible contact 360.

[0114] like Figure 1As shown, in some embodiments, the positioning device 40 includes a gripping part 410 and a positioning part 420; the gripping part 410 is movably disposed on the frame 10 and located on the side of the second gripping assembly 30 away from the first gripping assembly 20, and the gripping part 410 is configured to grip the workpiece on the second gripping assembly 30 and keep the workpiece in a horizontal state; the positioning part 420 is disposed on the frame 10 and located below the gripping part 410, and the positioning part 420 is configured to receive the workpiece transferred by the gripping part 410 and position the workpiece.

[0115] The clamping part 410 picks up the workpiece from the second clamping assembly and transfers the workpiece to the positioning part 420; the positioning part 420 positions the workpiece to calibrate and adjust the position of the workpiece on the positioning station 430, so that the positioned workpiece can be placed in the target position, thereby ensuring that the workpiece is placed in place and improving the assembly quality and assembly efficiency of the product.

[0116] In some embodiments, the clamping structure further includes a second translation mechanism disposed on the frame 10, the second translation mechanism being configured to drive the clamping part 410 to move along the length direction and the height direction.

[0117] The second translation mechanism drives the clamping part 410 to move, providing a structural basis for the clamping part 410 to clamp the workpiece from the second clamping assembly 30 and transfer the clamped workpiece to the positioning part 420.

[0118] It should be noted that the specific structure and working principle of the second translation mechanism are existing technologies. For example, the second translation mechanism is a lead screw linear module or a gear and rack linear module, which will not be described in detail in this application. In addition, the second translation mechanism can also be a three-axis linear module, which drives the clamping part 410 to move along the length direction, height direction and width direction.

[0119] like Figure 4 As shown, in some embodiments, the clamping part 410 includes a base plate 4105 and a plurality of third clamping components 4101. The base plate 4105 is disposed on the second translation mechanism. The plurality of third clamping components 4101 are arranged at intervals along the width direction of the frame 10. Each third clamping component 4101 includes a third clamping cylinder 4102, two third clamping jaws 4103, and a third flexible contact member 4104. The third clamping cylinder 4102 is disposed on the base plate 4105 and includes two third slides with opposite directions of movement. The two third clamping jaws 4103 correspond one-to-one with the two third slides and are disposed on the corresponding third slides to clamp or release the workpiece. The third flexible contact member 4104 is disposed at the end of the third clamping jaw 4103 away from the third slide to contact the workpiece.

[0120] The third clamping cylinder 4102 drives the two third slides to move in opposite directions, and the third clamping jaw 4103 moves with the corresponding third slide, thereby clamping or releasing the workpiece. By setting the third flexible contact 4104 to abut against the workpiece when clamping, it plays a role in flexible pressing, realizing flexible clamping and reducing the phenomenon of pressure damage and scratches caused by hard pressing, thereby further improving the product quality pass rate. At the same time, the third flexible contact 4104 can evenly distribute pressure when clamping the workpiece, avoiding the phenomenon of uneven pressure in the traditional mode, and improving the assembly quality and efficiency of the product.

[0121] It should be noted that the third flexible contact 4104 is a rubber contact.

[0122] It should also be noted that the two third slides move in opposite directions along the width. The contact length between the third clamping assembly 4101 and the workpiece can be adjusted by adjusting the third clamping cylinder 4102 and replacing the third flexible contact 4104.

[0123] It should also be noted that the number of third gripping components 4101 is equal to the number of positioning stations 430, and the number of third gripping components 4101 is greater than the number of first gripping components 20. The third gripping components 4101 are used to balance the cycle time and increase efficiency; for example, as... Figure 1 , Figures 4-6 As shown, there are four of each of the third clamping component 4101 and the positioning station 430, and two of each of the first clamping component 20 and the second clamping component 30, so that the positioning part 420 can position four workpieces at once.

[0124] It should also be noted that the third gripper 4103 can be made of one of the following materials: soft iron, silicon steel or nickel-iron alloy.

[0125] like Figure 5 , Figure 6As shown, in some embodiments, the positioning unit 420 includes a positioning fixture base 4201, a plurality of positioning fixture trays 4202, a plurality of first calibration components 4203, and a second calibration component 4204; the positioning fixture base 4201 is disposed on the frame 10; the plurality of positioning fixture trays 4202 are disposed on the positioning fixture base 4201 and arranged sequentially along the width direction, and the plurality of positioning fixture trays 4202 correspond one-to-one with the plurality of third clamping components 4101, and the positioning station 430 is disposed on the positioning fixture tray. On 4202; multiple first calibration components 4203 are disposed on the positioning fixture base 4201 and correspond one-to-one with the positioning fixture tray 4202; a second calibration component 4204 is disposed on the positioning fixture base 4201; wherein, the first calibration component 4203 is configured to drive the corresponding workpiece on the positioning fixture tray 4202 to move along the width direction, and the second calibration component 4204 is configured to drive the workpiece on the positioning fixture tray 4202 to move along the length direction, so that the workpiece moves to the target position.

[0126] The first calibration component 4203 drives multiple workpieces to move along the width direction at one time, and the second calibration component 4204 drives multiple workpieces to move along the length direction at one time, thereby moving multiple workpieces to the target simultaneously at one time, realizing one-time calibration and adjustment. This not only ensures that the workpieces are placed in place, but also improves the product assembly efficiency.

[0127] Example 4

[0128] like Figure 1 , Figure 5 As shown, the clamping structure includes a frame 10, a clamping device, and a positioning device 40. The clamping device is mounted on the frame 10 and is configured to clamp the workpiece and adjust it from a vertical to a horizontal position. The positioning device 40 is mounted on the frame 10 and includes a positioning station 430. The positioning device 40 is configured to horizontally transfer the workpiece from the clamping device to the positioning station 430 and position the workpiece.

[0129] As can be seen above, the clamping device grips the workpiece and adjusts it to a horizontal position, facilitating the subsequent receiving and transfer of the workpiece by the positioning device. By setting the positioning device 40 to calibrate and adjust the position of the workpiece on the positioning station 430, the positioned workpiece can be placed in the target position, thereby ensuring that the workpiece is placed in place, improving the assembly quality and efficiency of the product. Compared with the existing shell assembly process, this improves production efficiency, optimizes product quality, and provides a foundation for the precise assembly of the product.

[0130] It should be noted that the workpiece includes, but is not limited to, the remote control faceplate.

[0131] It should also be noted that the clamping structure also includes a turnover box located below the first clamping component 20. The turnover box contains multiple workpieces, and all the workpieces in the turnover box are in a vertical position. The first clamping component 20 clamps the vertical workpieces from the turnover box.

[0132] In some embodiments, the clamping device includes a plurality of first clamping components 20 and a plurality of second clamping components 30; the plurality of first clamping components 20 are movably disposed on the frame 10 to clamp and transfer workpieces; the plurality of second clamping components 30 are disposed on the frame 10 and located on the moving path of the first clamping components 20, and the second clamping components 30 are configured to receive the workpieces transferred by the first clamping components 20 and adjust the workpieces from a vertical state to a horizontal state.

[0133] By setting up multiple first clamping components 20 and multiple second clamping components 30 to clamp multiple workpieces simultaneously and transferring the clamped workpieces to the positioning station 430 for positioning, preparation is made for the assembly of the remote control. This achieves clamping and positioning of multiple workpieces at one time, thereby shortening the process cycle and improving production efficiency.

[0134] It should also be noted that, such as Figure 1 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction. Furthermore, the workpiece can be vertical (parallel to the height direction) or horizontal (parallel to the length direction).

[0135] It should also be noted that the number of the first clamping component 20, the second clamping component 30, and the positioning device 40 can be set according to specific needs. Specifically, the number of the first clamping component 20 and the second clamping component 30 can be equal, the number of positioning stations 430 can be more than the number of the first clamping component 20, and the second clamping component 30 can clamp the workpiece multiple times and transfer it to the positioning station 430 to ensure that each positioning station 430 is equipped with a workpiece, so that the positioning device 40 can position multiple workpieces at the same time and complete the positioning in one go. For example, the number of the first clamping component 20 and the second clamping component 30 can both be two, and the number of positioning stations 430 can be four.

[0136] In some embodiments, the clamping structure further includes a first translation mechanism disposed on the frame 10, the first translation mechanism being configured to drive the first clamping assembly 20 to move along the length direction and height direction of the frame 10.

[0137] The first translation mechanism drives the first clamping assembly 20 to move, providing a structural basis for the first clamping assembly 20 to clamp the workpiece from the turnover box and transfer the clamped workpiece to the second clamping assembly 30.

[0138] It should be noted that the specific structure and working principle of the first translation mechanism are existing technologies. For example, the first translation mechanism is a lead screw linear module or a gear and rack linear module, which will not be described in detail in this application.

[0139] like Figure 2 As shown, in some embodiments, a plurality of first gripping assemblies 20 are arranged at intervals along the width direction of the frame 10. Each first gripping assembly 20 includes a first base 210, a first gripping cylinder 220, two first gripping jaws 230, and a first flexible contact member 240. The first base 210 is disposed on a first translation mechanism. The first gripping cylinder 220 is disposed on the first base 210 and includes two first slides 250, which move in opposite directions. The two first gripping jaws 230 correspond one-to-one with the two first slides 250 and are disposed on the corresponding first slides 250 to clamp or release the workpiece. The first flexible contact member 240 is disposed at the end of the first gripping jaw 230 away from the first slide 250 to contact the workpiece.

[0140] The first clamping assembly 20 clamps the vertically positioned workpiece. The first clamping cylinder 220 drives two first slides 250 to move in opposite directions, and the first clamping jaws 230 move with the corresponding first slides 250, thereby clamping or releasing the workpiece. By setting a first flexible contact member 240 to abut against the workpiece during clamping, a flexible pressing effect is achieved, reducing damage and scratches caused by rigid pressing, thus further improving the product quality pass rate. Simultaneously, the first flexible contact member 240 can evenly distribute pressure during clamping, avoiding the uneven pressure phenomenon of traditional methods, improving product assembly quality and efficiency.

[0141] It should be noted that the first flexible contact 240 is a rubber contact.

[0142] It should also be noted that, such as Figure 2 As shown, the two first slides 250 move along the width direction and in opposite directions. The first clamping assembly 20 also includes two transition blocks 260, which correspond one-to-one with the two first slides 250. The transition blocks 260 are provided with a plurality of transition threaded holes arranged at intervals along the height direction, and the first clamping jaws 230 are provided with fixed threaded holes. The user can select the appropriate transition threaded holes to connect with the fixed threaded holes according to the installation needs, and use screws to fix the transition blocks 260 and the first clamping jaws 230, thereby adjusting the installation height of the first clamping jaws 230 and thus adjusting the effective clamping length.

[0143] It should also be noted that the first gripping cylinder 220 includes, but is not limited to, the finger slide cylinder.

[0144] like Figure 1 , Figure 3 As shown, in some embodiments, a plurality of second gripping components 30 are arranged at intervals along the width direction, and each of the plurality of second gripping components 30 corresponds one-to-one with a plurality of first gripping components 20. Each second gripping component 30 includes a rotary drive 310, a second base 320, a second gripping cylinder 330, two second gripping jaws 340, and a second flexible contact member 360. The rotary drive 310 is disposed on the frame 10. The second base 320 is disposed on the rotating shaft of the rotary drive 310. The second gripping cylinder 330 is disposed on the second base 320 and includes two second slides 350, the two slides 350 moving in opposite directions. The two second gripping jaws 340 correspond one-to-one with the two second slides 350, and the second gripping jaws 340 are disposed on the corresponding second slides 350 to clamp or release the workpiece. The second flexible contact member 360 is disposed at the end of the second gripping jaw 340 away from the second slide 350 to contact the workpiece.

[0145] The second clamping cylinder 330 drives the two second slides 350 to move in opposite directions, and the second clamping jaws 340 move with the corresponding second slides 350, thereby clamping or releasing the workpiece. After the second clamping jaws 340 clamp the workpiece, the rotary drive 310 drives the second base 320 to rotate, and the workpiece rotates with the second base 320, thereby changing the vertical workpiece to a horizontal position, making it easier for the clamping part 410 to clamp the workpiece. By setting the second flexible contact member 360 to abut against the workpiece when clamping, it plays a role in flexible pressing, realizing flexible clamping and reducing the phenomenon of pressure damage and scratches caused by hard pressing, thereby further improving the product quality pass rate. At the same time, the second flexible contact member 360 can evenly distribute pressure when clamping the workpiece, avoiding the uneven pressure phenomenon of traditional mode, improving the assembly quality and efficiency of the product.

[0146] It should be noted that the second flexible contact 360 is a rubber contact; the second gripping cylinder 330 includes, but is not limited to, a finger slide cylinder; and the rotary drive 310 includes, but is not limited to, a motor.

[0147] It should also be noted that the two second slides 350 move along the width direction and in opposite directions.

[0148] It should also be noted that the second clamping assembly 30 can adjust the contact length with the workpiece by adjusting the second clamping cylinder 330 and replacing the second flexible contact 360.

[0149] like Figure 1As shown, in some embodiments, the positioning device 40 includes a gripping part 410 and a positioning part 420; the gripping part 410 is movably disposed on the frame 10 and located on the side of the second gripping assembly 30 away from the first gripping assembly 20, and the gripping part 410 is configured to grip the workpiece on the second gripping assembly 30 and keep the workpiece in a horizontal state; the positioning part 420 is disposed on the frame 10 and located below the gripping part 410, and the positioning part 420 is configured to receive the workpiece transferred by the gripping part 410 and position the workpiece.

[0150] The clamping part 410 picks up the workpiece from the second clamping assembly and transfers the workpiece to the positioning part 420; the positioning part 420 positions the workpiece to calibrate and adjust the position of the workpiece on the positioning station 430, so that the positioned workpiece can be placed in the target position, thereby ensuring that the workpiece is placed in place and improving the assembly quality and assembly efficiency of the product.

[0151] In some embodiments, the clamping structure further includes a second translation mechanism disposed on the frame 10, the second translation mechanism being configured to drive the clamping part 410 to move along the length direction and the height direction.

[0152] The second translation mechanism drives the clamping part 410 to move, providing a structural basis for the clamping part 410 to clamp the workpiece from the second clamping assembly 30 and transfer the clamped workpiece to the positioning part 420.

[0153] It should be noted that the specific structure and working principle of the second translation mechanism are existing technologies. For example, the second translation mechanism is a lead screw linear module or a gear and rack linear module, which will not be described in detail in this application. In addition, the second translation mechanism can also be a three-axis linear module, which drives the clamping part 410 to move along the length direction, height direction and width direction.

[0154] It should also be noted that the clamping structure also includes a control device, which controls the operation of the first translation mechanism, the second translation mechanism, the positioning device, and the clamping device to achieve automated operation. For example, the control device can be a PLC controller. The specific working principle and control method are existing technologies and will not be described in detail in this application.

[0155] like Figure 4As shown, in some embodiments, the clamping part 410 includes a base plate 4105 and a plurality of third clamping components 4101. The base plate 4105 is disposed on the second translation mechanism. The plurality of third clamping components 4101 are arranged at intervals along the width direction of the frame 10. Each third clamping component 4101 includes a third clamping cylinder 4102, two third clamping jaws 4103, and a third flexible contact member 4104. The third clamping cylinder 4102 is disposed on the base plate 4105 and includes two third slides with opposite directions of movement. The two third clamping jaws 4103 correspond one-to-one with the two third slides and are disposed on the corresponding third slides to clamp or release the workpiece. The third flexible contact member 4104 is disposed at the end of the third clamping jaw 4103 away from the third slide to contact the workpiece.

[0156] The third clamping cylinder 4102 drives the two third slides to move in opposite directions, and the third clamping jaw 4103 moves with the corresponding third slide, thereby clamping or releasing the workpiece. By setting the third flexible contact 4104 to abut against the workpiece when clamping, it plays a role in flexible pressing, realizing flexible clamping and reducing the phenomenon of pressure damage and scratches caused by hard pressing, thereby further improving the product quality pass rate. At the same time, the third flexible contact 4104 can evenly distribute pressure when clamping the workpiece, avoiding the phenomenon of uneven pressure in the traditional mode, and improving the assembly quality and efficiency of the product.

[0157] It should be noted that the third flexible contact 4104 is a rubber contact.

[0158] It should also be noted that the two third slides move in opposite directions along the width. The contact length between the third clamping assembly 4101 and the workpiece can be adjusted by adjusting the third clamping cylinder 4102 and replacing the third flexible contact 4104.

[0159] It should also be noted that the number of third gripping components 4101 is equal to the number of positioning stations 430, and the number of third gripping components 4101 is greater than the number of first gripping components 20. The third gripping components 4101 are used to balance the cycle time and increase efficiency; for example, as... Figure 1 , Figures 4-6 As shown, there are four of each of the third clamping component 4101 and the positioning station 430, and two of each of the first clamping component 20 and the second clamping component 30, so that the positioning part 420 can position four workpieces at once.

[0160] It should also be noted that the third gripper 4103 can be made of one of the following materials: soft iron, silicon steel or nickel-iron alloy.

[0161] like Figure 5 , Figure 6 As shown, in some embodiments, the positioning unit 420 includes a positioning fixture base 4201, a plurality of positioning fixture trays 4202, a plurality of first calibration components 4203, and a second calibration component 4204; the positioning fixture base 4201 is disposed on the frame 10; the plurality of positioning fixture trays 4202 are disposed on the positioning fixture base 4201 and arranged sequentially along the width direction, and the plurality of positioning fixture trays 4202 correspond one-to-one with the plurality of third clamping components 4101, and the positioning station 430 is disposed on the positioning fixture tray. On 4202; multiple first calibration components 4203 are disposed on the positioning fixture base 4201 and correspond one-to-one with the positioning fixture tray 4202; a second calibration component 4204 is disposed on the positioning fixture base 4201; wherein, the first calibration component 4203 is configured to drive the corresponding workpiece on the positioning fixture tray 4202 to move along the width direction, and the second calibration component 4204 is configured to drive the workpiece on the positioning fixture tray 4202 to move along the length direction, so that the workpiece moves to the target position.

[0162] The first calibration component 4203 drives multiple workpieces to move along the width direction at one time, and the second calibration component 4204 drives multiple workpieces to move along the length direction at one time, thereby moving multiple workpieces to the target simultaneously at one time, realizing one-time calibration and adjustment. This not only ensures that the workpieces are placed in place, but also improves the product assembly efficiency.

[0163] like Figure 5 , Figure 6 As shown, in some embodiments, the positioning fixture tray 4202 includes a first side and a second side disposed opposite to each other in the width direction. A fixed top block 4205 is disposed on the first side. The first calibration component 4203 includes a first calibration drive and a movable top block 4206. The first calibration drive is disposed on the positioning fixture base 4201. The movable top block 4206 is disposed on the telescopic rod of the first calibration drive and located on the second side, so that the movable top block 4206 and the fixed top block 4205 respectively abut against the workpiece under the action of the first calibration drive.

[0164] The first calibration drive unit drives the movable top block 4206 to move along the width direction, so that the movable top block 4206 abuts against the workpiece. The first calibration drive unit continues to drive the movable top block 4206 to move, so that the side of the workpiece away from the movable top block 4206 moves to abut against the fixed top block 4205.

[0165] It should be noted that there can be multiple movable top blocks 4206 and fixed top blocks 4205. Multiple movable top blocks 4206 are arranged at intervals along the length direction, and multiple fixed top blocks 4205 are arranged at intervals along the length direction.

[0166] It should also be noted that the first calibration drive component includes, but is not limited to, a cylinder and an electric push rod; of course, the first calibration drive component can be a motor and a lead screw drive, by setting the movable top block 4206 on the lead screw, and using the rotation of the motor to drive the movable top block 4206 to move.

[0167] like Figure 5 , Figure 6 As shown, in some embodiments, the positioning fixture tray 4202 includes a third side and a fourth side arranged opposite to each other in the length direction, and a fixed baffle 4210 is provided on the third side; the second calibration component 4204 includes a second calibration drive, a transmission rod 4207, a support member 4208, and a plurality of movable baffles 4209; the second calibration drive is disposed on the positioning fixture base 4201; the transmission rod 4207 is disposed on the telescopic rod of the second calibration drive; the support member 4208 is disposed on the transmission rod 4207; the plurality of movable baffles 4209 are disposed on the support member 4208 and located on the fourth side, and the plurality of movable baffles 4209 are spaced apart in the width direction, and the plurality of movable baffles 4209 correspond one-to-one with the plurality of positioning fixture trays 4202; wherein, the second calibration drive drives the movable baffles 4209 to move in the length direction so that the fixed baffle 4210 and the movable baffles 4209 respectively abut against the workpiece.

[0168] The second calibration drive unit drives the transmission rod 4207 to move along the length direction. The support member 4208 and the movable baffle 4209 move with the transmission rod 4207, so that the movable baffle 4209 abuts against the workpiece. Then the second calibration drive unit continues to drive the movable baffle 4209 to move, so that the side of the workpiece away from the movable baffle 4209 moves to abut against the fixed baffle 4210.

[0169] It should be noted that the second calibration drive component includes, but is not limited to, cylinders and electric push rods; of course, the second calibration drive component can be a motor and a lead screw drive, by setting the transmission rod 4207 on the lead screw, and using the rotation of the motor to drive the transmission rod 4207 and the movable baffle 4209 to move.

[0170] It should also be noted that the target position is the position where the workpiece simultaneously abuts against the fixed top block 4205 and the fixed baffle 4210.

[0171] It should also be noted that, such as Figure 1As shown, the first clamping component 20 clamps the vertically positioned workpiece from the turnover box and transfers it to the second clamping component 30; the second clamping component 30 takes the workpiece from the first clamping component 20 and changes the vertically positioned remote control to a horizontal position; the third clamping component 4101 takes the workpiece from the second clamping component 30 and waits for the second clamping component 30 to perform the next clamping operation. After all four third clamping components 4101 have clamped workpieces, the four workpieces are transferred to the positioning station 430 at once; the first calibration component 4203 and the second calibration component 4204 position and calibrate the four workpieces to the target position at once, and then the assembly operation is performed.
