Description

Technical Field

[0001] The present invention relates to the technical field of antenna manufacturing, and in particular to an antenna bending device. Background Art

[0002] The built-in antenna of a mobile phone is a radio wave receiving and transmitting device built into the mobile phone. It is responsible for receiving and sending radio signals, enabling the mobile phone to communicate with base stations or other devices.

[0003] As mobile phones are becoming smaller, lighter and thinner, the space inside the phone is becoming increasingly limited. In order to design an antenna with excellent performance within the limited space, it is often necessary to bend the antenna to fit the edge of the phone case. This ensures that the antenna can maximize its function without affecting the overall size of the device.

[0004] However, currently most antennas are bent manually with the help of bending tools. However, the bending consistency of the antennas bent in this way is poor, which can easily lead to the actual bending surface of the antenna not being able to perfectly match the ideal bending surface, ultimately making it difficult for the antenna to fit completely on the edge of the mobile phone case, thereby affecting the assembly quality of the mobile phone. Summary of the invention

[0005] Based on this, an object of the present invention is to provide an antenna bending device, which can accurately bend the antenna and improve the matching degree between the actual bending surface of the antenna and the ideal bending surface.

[0008] In addition, the antenna bending device according to the present invention may also have the following additional technical features:

[0009] Furthermore, the pressing assembly includes a pressing plate and a first driving mechanism. The pressing plate is rotatably arranged on a support platform. The first driving mechanism is transmission-connected to the pressing plate to drive the pressing plate to rotate. When the antenna bending device is in a preparatory state, the first driving mechanism drives the pressing plate to press against the second surface.

[0010] Furthermore, the first driving mechanism includes a first rotating cylinder, which is disposed on the supporting platform, and a rotating shaft of the first rotating cylinder is connected to the pressing plate.

[0011] Furthermore, the first bending component includes a turn block and a second driving mechanism. The turn block is rotatably arranged on the support platform and is located on the side of the support surface opposite to the pressing component. A push surface is provided on the side of the turn block close to the support surface. The area of ​​the push surface matches the area of ​​the first area to be bent. The second driving mechanism is transmission-connected to the turn block to drive the turn block to rotate; wherein the edge line of the push surface close to the support surface coincides with the support surface and coincides with the rotation axis of the turn block, and the bending axis between the first end and the first area to be bent is parallel to the rotation axis of the turn block.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] See also Figure 1 , is a schematic diagram of the structure of the antenna 100 after being bent in the present invention, wherein the antenna 100 has a first end 110 and a second end 120 arranged opposite to each other, a first to-be-bent region 121 is provided in the middle of the second end 120, and second to-be-bent regions 122 are provided on both sides of the second end 120 along the bending axis direction, and the second to-be-bent regions 122 are adjacent to both sides of the first to-be-bent region 121. After the antenna bending device bends the antenna 100, the angle between the first to-be-bent region 121 and the second to-be-bent region 122 and the surface of the first end 110 is changed from a straight angle to a preset angle, for example, bent to ninety degrees.

[0039] Please refer to Figures 2 to 7 , which is an antenna bending device provided by the present invention, the antenna bending device includes a support platform 200, a pressing component 300, a first bending component 400, a second bending component 500, and a shaping component 600.

[0040] The support platform 200 has a support surface 210, and the support surface 210 covers the lower surface of the first end 110, so as to support the antenna 100. Optionally, the area of ​​the support surface 210 may be larger than the area of ​​the lower surface of the first end 110, or smaller than the area of ​​the lower surface of the first end 110, or equal to the area of ​​the lower surface of the first end 110. Of course, in order to provide stable support for the antenna 100, preferably, the area of ​​the support surface 210 is set to be larger than the area of ​​the lower surface of the first end 110.

[0041] The pressing assembly 300 has a pressing portion, which covers the upper surface of the first end 110, so that the antenna 100 can be pressed toward the side of the support surface 210, so that the antenna 100 can be tightly clamped between the support surface 210 and the pressing portion during the bending process. Optionally, the area of ​​the pressing portion can be larger than the area of ​​the upper surface of the first end 110, or smaller than the area of ​​the upper surface of the first end 110, or equal to the area of ​​the upper surface of the first end 110. Of course, in order to form a stable downward pressure on the antenna 100, it is preferred that the area of ​​the pressing portion is set to be larger than the area of ​​the upper surface of the first end 110. It should be noted that the upper surface of the first end 110 is a plane arranged opposite to the lower surface of the first end 110.

[0042] The first bending assembly 400 has a first rotatable pushing portion, which contacts the first area to be bent 121 to push the first area to be bent 121 toward the first end 110, so that the angle between the first area to be bent 121 and the second area to be bent 122 and the surface of the first end 110 changes from a straight angle to a preset angle. It should be noted that although the first pushing portion does not contact the second area to be bent 122, since the second area to be bent 122 and the first area to be bent 121 are connected together, when the first area to be bent 121 is bent, the second area to be bent 122 will also be bent. Optionally, in order to form a stable pushing force on each local area of ​​the first area to be bent 121, the area of ​​the first pushing portion needs to be greater than or equal to the area of ​​the first area to be bent 121.

[0043] The second bending assembly 500 has a second pushing portion that can move horizontally, and the second pushing portion contacts the second area to be bent 122 to push the second area to be bent 122 toward the middle of the first end 110, so that the second area to be bent 122 forms a preset curvature. Optionally, in order to form a stable pushing force on each local area of ​​the second area to be bent 122, the area of ​​the second pushing portion needs to be greater than or equal to the area of ​​the second area to be bent 122.

[0044] The shaping component 600 has a positioning portion. When the antenna bending device is in the bending state, the positioning portion presses the upper surface of the first end 110, so that the antenna 100 is tightly clamped between the support surface 210 and the positioning portion. In addition, since the first bending area 121 and the second bending area are not converted to the preset bending state after the antenna bending device completes the conversion of the preparatory state, the shaping component 600 also has a shaping portion that matches the shape of the antenna in the preset bending state. Through the cooperation of the shaping portion and the first bending component 400 and the second bending component 500, the first bending area 121 and the second bending area are converted to the preset bending state, thereby completing the bending operation of the antenna 100.

[0045] In this embodiment, the antenna bending device has a preparatory state and a bending state which are sequentially distributed in time. Among them, when the antenna bending device is in the preparatory state, the pressing portion presses against the upper surface of the first end 110, and then the first pushing portion pushes the first area to be bent 121 until a preset obtuse angle is formed between the first area to be bent 121 and the support surface 210. Preferably, the preset obtuse angle ranges from 139 degrees to 140 degrees. When the antenna bending device is in the bending state, the positioning portion presses against the upper surface of the first end 110 toward one side of the support surface 210, and then the second pushing portion pushes the second area to be bent 122 until the second area to be bent 122 is attached to the shaping portion, and then the first pushing portion pushes the first area to be bent 121 until the first area to be bent 121 is attached to the shaping portion, and finally the antenna 100 is converted into a preset bending state.

[0046] In some optional embodiments, such as Figure 2 , Figure 3 As shown, the pressing assembly 300 includes a pressing plate 310 and a first driving mechanism 320. The pressing plate 310 is rotatably disposed on the support platform 200. The first driving mechanism 320 is transmission-connected with the pressing plate 310 to drive the pressing plate 310 to rotate. When the first driving mechanism 320 is in a working state, the first driving mechanism 320 drives the pressing plate 310 to rotate until the pressing plate 310 is pressed against the upper surface of the first end 110.

[0047] In some optional embodiments, the first driving mechanism 320 includes a first rotating cylinder, which is disposed on the support platform 200, and the rotating shaft of the first rotating cylinder is connected to the pressing plate 310. When working, by inputting gas into the first rotating cylinder, the rotating shaft of the first rotating cylinder can be driven to rotate. In this embodiment, since the rotating cylinder has a built-in precision transmission mechanism, it is possible to achieve precise rotation control of the pressing plate 310 to ensure that the preset process requirements can be met.

[0048] In some optional embodiments, such as Figure 6 As shown, the pressing plate 310 is a two-stage flat plate structure arranged at a high and low position, wherein the first section 310a is used to press against the upper surface of the first end 110, and the second section 310b serves to connect the first section 310a and the first driving mechanism 320. In addition, when the first section 310a presses against the upper surface of the first end 110, the surface of the second section 310b close to the supporting surface 210 is flush with the supporting surface 210 and partially overlaps with the supporting surface 210, so that when the first bending assembly 400 located on the opposite side of the pressing plate 310 pushes the first to-be-bent area 121 toward the first end 110, the first end 110 of the antenna 100 cannot move horizontally due to the blocking force applied by the second section 310b, thereby ensuring that the position of the antenna 100 does not deviate when bending.

[0049] In some optional embodiments, such as Figure 2 , Figure 3 As shown, the first bending assembly 400 includes a rotating block 410 and a second driving mechanism 420. The rotating block 410 is rotatably arranged on the support platform 200, and the rotating block 410 is located on the side of the support surface 210 relative to the pressing assembly 300. A pushing surface 411 is provided on the side of the rotating block 410 close to the support surface 210, and the area of ​​the pushing surface 411 matches the area of ​​the first area to be bent 121, so as to ensure that when the rotating block 410 pushes the first area to be bent 121, the pushing surface 411 completely covers the first area to be bent 121. The second driving mechanism 420 is transmission-connected to the rotating block 410 to drive the rotating block 410 to rotate. When the rotating block 410 rotates, in order to ensure that the pushing surface 411 can fit well in the first area to be bent 121, the edge line of the pushing surface 411 close to the supporting surface 210 coincides with the supporting surface 210, and the edge line coincides with the rotation axis of the rotating block 410, and the bending axis between the first end 110 and the first area to be bent 121 is parallel to the rotation axis of the rotating block 410.

[0050] In some optional embodiments, the second driving mechanism 420 includes a second rotary cylinder, which is disposed on the support platform 200, and the rotating shaft of the second rotary cylinder is connected to the rotating block 410. During operation, by inputting gas into the second rotary cylinder, the rotating shaft of the second rotary cylinder can be driven to rotate. In this embodiment, since the rotary cylinder has a built-in precision transmission mechanism, it is possible to achieve precise rotation control of the rotating block 410, ensuring that the preset process requirements can be met.

[0051] In some optional embodiments, such as Figure 2 , Figure 3 As shown, the second bending assembly 500 includes a push plate 510 and a third driving mechanism 520. The end of the push plate 510 close to the support surface 510 is provided with an arc segment 511 matching the shape of the second to-be-bent area 122 after bending. The area of ​​the arc segment 511 is greater than or equal to the area of ​​the second to-be-bent area 122, so that when the push plate 510 pushes the second to-be-bent area 122, the arc segment 511 can be well fitted in the second to-be-bent area 122. The third driving mechanism 520 is in transmission connection with the push plate 510 to drive the push plate 510 to approach or move away from the support surface 210.

[0052] In some optional embodiments, the third driving mechanism 520 includes a slide cylinder, the slide cylinder is arranged on the support table 200, and the push plate 510 is fixed on the slide of the slide cylinder. During operation, by inputting gas into the slide cylinder, the slide of the slide cylinder can be pushed to move horizontally on the linear track of the slide cylinder. It should be noted that in order to avoid the slide of the slide cylinder from hitting the support table 200, the height of the slide of the slide cylinder cannot be less than the height of the support surface 210. In this embodiment, the slide cylinder can realize stable linear motion of the push plate 510 to ensure accurate bending of the second area to be bent 122.

[0053] In some optional embodiments, such as Figure 7 As shown, the shaping component 600 includes a first vacuum suction head 610, which is used to connect to an external vacuum pump. The shape of the suction nozzle of the first vacuum suction head 610 matches the shape of the antenna 100 in a preset bending state. The suction nozzle of the first vacuum suction head 610 and the upper surface of the first end 110, the first to-be-bent area 121 and the second to-be-bent area 122 are distributed with first suction holes 611. When the antenna bending device is in the bending state, the bottom of the nozzle of the first vacuum suction head 610 sucks the upper surface of the first end 110, and at the same time presses the upper surface of the first end 110 toward the support surface 210, so that the antenna 100 is firmly supported on the support surface 210 to prevent the position from deviating during subsequent bending; then, the second pushing portion pushes the second area to be bent 122 until the second area to be bent 122 is attached to the nozzle of the first vacuum suction head 610, and under the negative pressure state generated by the first suction hole 611, the second area to be bent 122 is stably attached to the nozzle, thereby maintaining the fixed state; then, the first pushing portion pushes the first area to be bent 121 until the first area to be bent 121 is attached to the nozzle of the first vacuum suction head 610, and under the negative pressure state generated by the first suction hole 611, the first area to be bent 121 is stably attached to the nozzle, thereby maintaining the fixed state. In this way, the antenna 100 is converted into a preset bending state.

[0054] In some optional embodiments, such as Figure 7 As shown, the shaping component 600 also includes a second vacuum head 620, which is used to connect to an external vacuum pump, and the second vacuum head 620 has second suction holes 621 distributed in the area corresponding to the suction nozzle and the first end 110. When the antenna bending device is in the preparatory state, under the negative pressure state generated by the second suction hole 621, the second vacuum head 620 transfers the antenna 100 to the support table 200 by suction, and then the second suction hole 621 releases the negative pressure state, and at this time, the antenna 100 is pressed against the side of the support surface 210 by the pressing component 300, so that the antenna 100 is tightly clamped between the support surface 210 and the pressing portion.

[0055] In some optional embodiments, the first vacuum head 610 and the second vacuum head 620 are both moved by a robot arm, so that automated operation can be achieved. In order to improve the utilization rate of the equipment, the first vacuum head 610 and the second vacuum head 620 can be assembled on the same robot arm at the same time. In addition, in order to prevent the first vacuum head 610 and the second vacuum head 620 from interfering with each other during operation, the first vacuum head 610 can be movably set on the robot arm, or the second vacuum head 620 can be movably set on the robot arm, or the first vacuum head 610 and the second vacuum head 620 can be movably set on the robot arm at the same time. Exemplarily, the first vacuum head 610 can be set on the robot arm through a first group of slide cylinders, and then the first vacuum head 610 can be set on the cylinder body of the first group of slide cylinders through a second group of slide cylinders.

[0056] When the antenna bending device is in the bending state, the bottom of the nozzle of the first vacuum suction head 610 sucks the upper surface of the first end 110 and presses the upper surface of the first end 110 toward the support surface 210. In the process of the rotating block 410 pushing the first to-be-bent area 121 until the first to-be-bent area 121 is attached to the shaping portion, if the rotating block 410 rotates too much, it will cause the rotating block 410 to hit the first vacuum suction head 610. For this reason, in some optional embodiments, such as Figure 3 As shown, the antenna bending device further includes a limiting device 700 , which is used to limit the rotation angle of the second rotary cylinder, thereby preventing the rotary block 410 from hitting the first vacuum suction head 610 .

[0057] Specifically, the limiting device 700 includes a collision block 710 and a stopper 720. The collision block 710 is arranged on the rotating shaft of the second rotary cylinder, and the stopper 720 is movably arranged beside the collision block 710. When the antenna bending device is in a bending state, the stopper 720 moves to a preset position on the rotation path of the collision block 710. When the second rotary cylinder drives the collision block 710 to rotate to the preset position, the collision block 710 hits the stopper 720, so that the second rotary cylinder stops rotating, so as to prevent the rotating block 410 from continuing to rotate beyond the current direction and hitting the first vacuum suction head 610.

[0058] In some cases, since the antenna 100 has a certain toughness, in order to make the first bending area 121 and the supporting surface 210 present a preset obtuse angle, the second rotating cylinder needs to repeatedly rotate at a large angle, which corresponds to the rotating block 410. The rotating block 410 needs to rotate back and forth multiple times to push the first bending area 121. Therefore, when the antenna bending device is in the preparatory state, the blocking member 720 needs to be moved out of the preset position on the rotation path of the impact block 710. At this time, the rotation angle of the second rotating cylinder is not restricted, so that the second rotating cylinder can rotate at a large angle.

[0059] Optionally, the stopper 720 can be moved by the telescopic cylinder 800. Specifically, the stopper 720 is arranged on the telescopic shaft of the telescopic cylinder 800. When the telescopic cylinder 800 is extended upward, the stopper 720 is located at a preset position on the rotation path of the impact block 710. When the telescopic cylinder 800 is retracted downward, the stopper 720 moves out of the preset position on the rotation path of the impact block 710. In addition, the telescopic cylinder 800 can be fixed on the support platform 200.
