Description

Technical Field

[0001] This application relates to the field of machining technology, and more specifically, to a pin bending device and a method for bending pins. Background Technology

[0002] Many products on the market are decorated with 3D logos. These 3D logos are typically attached to the product using pins. Figure 1 To ensure that the 3D logo 200 can be stably fixed on the product 100, the pins need to be bent 300 to restrict the movement of the 3D logo 200. There are generally at least two pins 300, so bending two pins 300 can basically ensure that the 3D logo 200 is effectively fixed. If the area of ​​the 3D logo 200 is relatively large, multiple pins 300 should be set accordingly. The number of pins 300 is set according to the actual situation.

[0003] Currently, the main method for bending the pin 300 is manual bending. Workers place the pre-installed pin 300 onto product 200, and the pin 300 passes through the pin hole of product 100.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0045] Embodiments of the pin bending device of this application

[0046] Please refer to Figure 1 and Figure 12The present application discloses a pin bending device for bending pins 300 on a three-dimensional logo 200 placed on a product 100. The device includes: a workbench 1, a support frame 2, and a bending mechanism 3. The workbench 1 is used to place the product 100, the support frame 2 is fixedly mounted on the workbench 1, and the bending mechanism 3 is mounted on the support frame 2 and corresponds to the position of the product 100.

[0047] The bending mechanism 3 includes a first bending component 31, which includes a vertical driving component 311 and a bending pressure block 314. The bending pressure block is connected to the vertical driving component. The bottom of the bending pressure block 314 is provided with a pressure block inclined surface 3141. The vertical driving component 311 drives the bending pressure block 314 to move toward the product, and causes the pressure block inclined surface 3141 to bend the pin 300.

[0048] The pins 300 are generally pin-shaped structures, manually pre-inserted into the 3D logo 200. Then, the 3D logo 200 with pins 300 is placed on the workbench 200, pins 300 facing upwards. Next, the product 100 is covered with the 3D logo 200, with the pins 300 protruding through the pin holes on the product. When the bending block 314 presses down, it contacts the pins 300. The appropriate bending block 314 is selected according to the different 3D logos 200 for bending. For example, in this embodiment, there are 5 pins 300 located in four directions. In this embodiment, the bottom surface of the bending block 314 must fall within the circle formed by the 5 pins 300, and the size of the bending block must be larger than the circle formed by the 5 pins 300 to pass through the inclined surface 3141 of the block. All pins 300 are bent. Specifically, the inclined surface 3141 of the bending block reduces the size of the end of the bending block 314 near the pins 300, making it smaller than the circle formed by the five pins. The size of the end of the bending block 314 away from the pins 300 is larger than the circle formed by the five pins. Therefore, the bending block 314 can enter the circle. As the bending block 314 continues to move, the inclined surface of the bending block begins to contact the five pins 300 and bends the pins 300. It is worth noting that in other embodiments of this application, the shape of the bending block 314 is not limited to the above. For example, the bending block 314 can be moved by a moving mechanism and the pins 300 can be bent multiple times. Even if the bottom surface of the bending block 314 does not completely fall into the circle formed by the multiple pins 300, all pins can still be bent.

[0049] Please refer to Figure 3 , Figure 5 and Figure 6The workbench 1 is provided with a processing plane 11, and the support frame 2 is provided on the processing plane 11. The support frame 2 is used to place the bending mechanism 3 and provide space for the bending mechanism 3 to move. The support frame 2 includes two vertical plates 22 and a horizontal plate 21. The two ends of the horizontal plate 21 are respectively connected to the two vertical plates 22. The bending mechanism 3 is provided on the horizontal plate 21. The position of the bending mechanism 3 corresponds to the position of the product 100, so that the bending pressure block 314 can accurately bend the pin 300 when it moves toward the product 100. The bending pressure block 314 of the first bending assembly moves toward the product direction by the drive of the vertical drive component, and guides the pin to bend through the inclined surface of the pressure block. In this embodiment, the vertical drive component is a cylinder. In other embodiments of this application, the vertical drive component can be a lead screw or other drive components.

[0050] By placing the product directly on the workbench, the bending block moves towards the product and bends the pins, replacing the time-consuming and labor-intensive problem of manual bending in existing technologies. At the same time, the mechanical bending method makes it easier to control the bending degree to be uniform. That is, mechanical bending can preset the same pin bending height, avoiding the wobbling of the 3D logo200 caused by the pins being bent at different heights after manual bending. The inclined plane guides the pin bending, which is simple in structure and provides stable and effective control of the bending method. In addition, mechanical bending can also control the bending speed and time of the bending block to avoid problems such as deformation and breakage of the pins due to sudden excessive force.

[0051] For details, please refer to Figure 7 The first bending assembly 31 further includes a fixing plate 315, which is connected to the output end of the vertical drive component 311, and the bending pressure block 314 is connected to the fixing plate 315.

[0052] The fixed plate 315 is used to drive the bending block 314 to move downward. The vertical drive component 311 drives the fixed plate 315 to move, thereby driving the bending block 314 to move towards the product 100.

[0053] Furthermore, the first bending assembly 31 also includes a movable plate 313, two guide posts 312, and a connecting post 316. The movable plate 313 is directly connected to the output end of the vertical drive component 311. The two guide posts 312 are symmetrically arranged on both sides of the vertical drive component 311, and the guide posts 312 connect the movable plate 313 and the horizontal plate 21. The movable plate 313 is connected to the fixed plate 315 through the two connecting posts 316. The size of the fixed plate 315 is smaller than that of the movable plate 313, so that the driving force output by the vertical drive component 311 to move downward can be concentrated, and it is also convenient to set the shape of the bending pressure block 314. The vertical drive component 311 drives the movable plate 313 to move towards the product 100. When the movable plate 313 moves, it drives the fixed plate 315 to move, thereby controlling the bending pressure block 314 to contact and bend the pin 200.

[0054] Further, please refer to Figure 7 , Figure 8 and Figure 9 The bending mechanism 3 further includes a second bending component 32, which is disposed on the end face of the fixed plate 315 near the product 100. The bending pressure block 314 is disposed on the second bending component 32. The second bending component 32 includes a rotary drive component 321, a rotary transmission component, and at least one flipping component 324. The rotary transmission component connects the rotary drive component 321 and the flipping component 324. The rotary drive component 321 drives the rotary transmission component to control the flipping component 324 to flip, so that the flipping component 324 flips the contact pin and bends the pin 200 again.

[0055] The second bending assembly 32 is disposed on the end face of the fixed plate 315 near the product. After the first bending assembly 31 bends the pin 200, the already bent pin 200 is further bent. The second bending assembly 32 bends the pin 200 by flipping, and the bending effect is significantly better than the vertical drive component 311 controlling the bending block 314 to press down the pin 200 alone.

[0056] Specifically, as the bending block moves and bends the pins, the bending direction of the pins at different positions is not the same. For example, as the bending block moves from top to bottom, the pins that come into contact with the four sides of the bending block face different directions. The pins closer to the east contact the inclined surface 3141 of the bending block on the east side, causing the pins closer to the east to bend at a certain angle to the east during the movement of the bending block. The pins closer to the west contact the inclined surface 3141 of the bending block on the west side, causing the pins closer to the west to bend at a certain angle to the east during the movement of the bending block. The same applies to the pins on the north and south sides.

[0057] The second bending component further bends the pin based on the bending of the first bending component, making the pin bend in a larger direction. That is, the bending direction of the second bending component is the same as the bending direction of the first bending component.

[0058] For further information, please continue to refer to [link / reference]. Figure 7 , Figure 8 and Figure 9 The rotary transmission assembly includes at least one connector 326, a fixing block 323, and a cam 325. The connector 326 is fixedly connected to the fixing plate 315 and is used to restrict the movement of the fixing block 323. The fixing block 323 is fixedly disposed on the connector 324, and the flipping assembly 324 is disposed on the outer periphery of the fixing block 323. The cam 325 is fixedly installed below the rotary drive component 321 and sleeved on the outer periphery of the flipping assembly 324. The rotary drive component drives the cam 325 to rotate, so that the cam 325 controls the flipping assembly 324 to flip. The bending pressure block 314 is disposed on the fixing block 323.

[0059] The connector 326 serves to fix the fixing block 323. In this embodiment, the fixing block 323 is fixed by two symmetrically arranged connectors 326 to avoid uneven force on a single connector 326. The flipping component 324 is disposed on the outer periphery of the fixing block 323. The fixing block 323 is limited by the connectors 326, so the fixing block 323 cannot move relative to the connectors 326. The cam 325 is connected to the rotary drive component 321. Under the control of the rotary drive component 321, the cam 325 rotates. The flipping component 324 is disposed on the outer periphery of the fixing block 323, and the cam 325 is sleeved on the outer periphery of the flipping component 324. The rotation of the cam 325 controls the flipping component 324 to rotate. The movement enables the flipping component 324 to bend the pin 300. Multiple flipping components 324 can be set on a fixed block 323, that is, the cam 325 can simultaneously control multiple flipping components 324 to flip. During the flipping process of multiple flipping components 324, multiple pins 300 can be bent. It is worth noting that one flipping component 324 can actually bend more than one pin 300. For example, if two pins 300 are close to each other, then one flipping component 324 can bend both pins 300 at the same time, and so on. In the embodiments of this application, the rotary drive component 321 adopts a rotary cylinder. In other embodiments of this application, a motor or other rotary drive components 321 can be adopted.

[0060] For further information, please continue to refer to [link / reference]. Figures 7-11The flipping assembly 324 includes a lug 3241, a flipping member 3242, and a flipping spring 3243. The lug 3241 is fixed to the outer periphery of the fixing block 323. The flipping member 3242 is hinged to the lug 3241. The flipping spring 3243 is disposed in the gap between the flipping member 3242 and the fixing block 323, and is located in the direction away from the product 200 of the lug 3241. The end of the flipping member 3242 near the flipping spring 3243 is connected to the cam 325. The cam 325 controls the part of the flipping member 3242 away from the product 200 to move inward or outward, so that the part of the flipping member 3242 near the product 200 flips outward or inward.

[0061] Lug 3241 is hinged to flip member 3242 to form a lever structure. That is, when one end of flip member 3242 moves, the other end, which is symmetrical with respect to lug, moves in the opposite direction. Flip spring 3243 is used to reset flip member 3242 to its initial position. One end of flip member 3242 is connected to cam 325, and cam 325 is sleeved on the outer periphery of flip member 3242. Cam 325 controls the part of flip member 3242 that contacts cam 325 to flip inward or outward toward the part of product 100. The other end flips outward or inward through the lever principle. When cam 325 controls the flip member 3242 that contacts cam 325 to flip inward, flip member 3242 can bend pin 300.

[0062] It is worth noting that in this embodiment, the part of product 100 is flipped outward or inward. Here, outward or inward refers to the positive or negative direction of the bending direction of pin 300. For example, if pin 300 has tilted to the east at a certain angle under the action of the first bending component, then the outward direction refers to the direction in which pin 300 has been bent and tilted, that is, the east direction. Similarly, the inward direction refers to the opposite direction in which pin 300 has been bent and tilted, that is, the west direction.

[0063] Further, please refer to Figure 11 and Figure 12The fixing block 323 is provided with a pressing chamber 3231 and a spring groove 3232. The pressing chamber 3231 and the spring groove 3232 are arranged in series. The pressing chamber 3231 passes through the upper and lower ends of the fixing block 323. The spring groove 3232 extends downward along the top of the fixing block 323. The inner diameter of the spring groove 3232 is larger than the inner diameter of the pressing chamber 3231. A step 323 is formed between the pressing chamber 3231 and the spring groove 3232. 5; A pressure block cap 3142 is provided on the top of the bending pressure block 314. The bending pressure block 314 is disposed in the pressure block chamber 31. The pressure block cap 3142 is locked on the step 3235. A downward pressure spring 317 is provided in the spring groove 3232. A blocking member 322 is provided on the fixing block 323 to restrict the downward pressure spring 317 from moving toward the blocking member 322. The contraction of the downward pressure spring 317 causes the flipping member 3242 to contact the pin 300.

[0064] The step 3235 is used to restrict the movement of the pressure block cap 3142, thereby limiting the maximum downward movement distance of the bending pressure block 314. Specifically, the bending pressure block 314 is disposed in the pressure block chamber 3231. Since the pressure block chamber 3231 is open, the bending pressure block 314 can extend / enter the pressure block chamber 3231. The pressure block cap 3142 is provided on the bending pressure block 314 to restrict the bending pressure block 314 from fully extending out of the pressure block chamber 3231, preventing the bending pressure block 314 from falling, and ensuring that the bending pressure block 314 has a certain space to move. The pressure block chamber 3231 is connected to the spring groove 3232. When the bending pressure block 314 retracts into the pressure block chamber 3231, the bending pressure block 314 can move into the spring groove 3232. A compression spring 317 is provided in the spring groove 3232 so that after the bending pressure block 314 bends the pin 300, the flipping part 3242 can directly contact the pin 300 and immediately bend the pin 300 a second time. This cleverly utilizes the fact that after the bending pressure block 314 bends the pin 300 for the first time, the pin 300 has already bent outwards to a certain extent, providing positional space for the flipping part 3242. At this time, the position of the flipping part 3242 can be directly above or slightly outward of the pin 300. Therefore, the bending pressure block 314 bends... After bending, the flipping component 3242 can immediately bend the pin 300 outward again, thus eliminating the need for a complex structure to control the flipping component 3242 to reach the appropriate position; in order to limit the upward movement of the compression spring 317, a retaining component 322 is provided above the fixing block 323. Both the retaining component 322 and the fixing block 323 are provided with pin holes. The retaining component 322 is fixed by passing the fixing pin through the pin hole between the two components; in other embodiments of this application, the retaining component 322 can be fixed by thread tightening, riveting, buckling, etc.

[0065] For further information, please continue to refer to [link / reference]. Figure 9 , Figure 10and Figure 11 The portion of the flipper 3242 near the product 100 extends toward the fixing block 323.

[0066] The part of the flipping component 3242 closer to the product 100 is closer to the fixing block 323, making the structure of the entire flipping assembly 324 more compact and also making it easier for the flipping component 3242 to bend the pin 300; a flange 3233 is provided on the outer periphery of the fixing block 323, and the flange 3233 is fixedly connected to the connector 326. The structure of the flange 3233 makes the structure of the entire second bending assembly 32 more compact.

[0067] Further, please refer to Figure 13 and Figure 14 The cam 325 includes at least one cam groove 3251 and at least one cam slide rail 3252. The cam groove 3251 and the cam slide rail 3252 are disposed on the inner circumferential surface of the cam. The cam groove 3251 is connected to the cam slide rail 3252. The flipping member 3242 moves along the cam groove 3251 and the cam slide rail 3252. The rotation of the cam 325 controls the movement of the flipping member 3242.

[0068] Multiple sets of cam grooves 3251 and cam slide rails 3252 can be provided to configure multiple sets of flipping components 324. The flipping components 324 are movably mounted on the fixed block 323. According to the actual processing needs of the pin 300, multiple or single sets of flipping components 324 can be provided. The cam 325 rotates under the drive of the rotary drive component 321, and at the same time controls the flipping of multiple sets of flipping components 324. The cam groove 3251 and cam slide rail 3252 are provided on the inner circumferential surface of the cam 325, and the depth of the cam groove 3251 is greater than that of the cam slide rail 3252. In the static state, the flipping component 3242 stays in the cam groove 3251 and is not controlled by the cam. After the cam 325 rotates, the flipping component 3242 flips under the guidance of the cam slide rail 3252, that is, the pin 300 is bent again.

[0069] Furthermore, the at least one cam groove 3251 and the at least one cam slide rail 3252 form a loop.

[0070] The cam groove 3251 and the cam slide rail 3252 form a loop, meaning that the rotary drive component 321 only needs to rotate in one direction to achieve bending and resetting. Unidirectional rotation is more conducive to improving processing efficiency.

[0071] For details, please continue to refer to Figure 5A mold 12 is installed on the working plane 11. The mold 12 is designed according to the structure of the product 100. Different molds 12 are replaced according to different products 100. A mold groove 121 is provided on the mold 12 for placing the three-dimensional logo 200. In the actual processing, the three-dimensional logo is placed in the mold groove with the pins 300 facing outward. Then the product 100 is placed on the mold, and the pin bending device is started to complete the processing.

[0072] Specifically, the workbench 1 also includes a time relay 15, which controls the dwell time of the bending block 314 after bending the pin.

[0073] The workbench 1 also includes a power switch 13, an emergency stop switch 14, a time relay 15, and two touch switches 16. The power switch 13 is used to start the equipment and enter the standby state. The emergency stop switch 14 is used to control the emergency stop of the equipment. The time relay 15 is used to control the processing time, speed, and dwell time of the vertical drive component 311 or the rotary drive component 321. The processing time of the pins of different materials is set according to their physical properties or actual needs. The two touch switches 16 are used to trigger the operation of the vertical drive component 311 or the rotary drive component 321. In order to prevent technicians from entering the processing area during processing, the two touch switches 16 need to be pressed at the same time to activate the operation of the vertical drive component 311 or the rotary drive component 321, so as to ensure the safety of technicians.

[0075] Step S01: Place the product with the pins to be bent facing the pin bending device, with the pins to be bent facing the bending mechanism;

[0076] Step S02: The vertical drive component 311 of the first bending assembly drives the bending pressure block 314 to contact and bend the pin 300, completing the first bending of the pin 300.

[0077] The above bending method replaces manual bending of pin 300, saving labor and improving work efficiency. The pin 300 is bent to the same degree, ensuring that pin 300 is stably fixed on product 100.

[0078] Furthermore, after completing the first bend of pin 300, the method for bending the pin also includes:

[0079] Step S03: The rotation drive component of the second bending component 32 drives the rotation transmission component to control the flipping component 324 to flip, so that the flipping component 324 contacts the pin after the first bend and performs a second bend on the pin 300.

[0080] Specifically, the rotary transmission assembly includes at least one connector 326, a fixing block 323, and a cam 325. The flipping assembly 324 includes a lug 3241, a flipping member 3242, and a flipping spring 3243. Step S03 specifically includes:

[0081] The rotary drive component 321 drives the cam 325 to rotate, flipping the flipper 3242 from the cam groove 3251 to the cam slide rail 3252, so that the flipper 3242 can bend the pin 300 after the first bend, completing the second bend of the pin 300.

[0082] Step S04: Reset the first bending assembly and the second bending assembly.

[0083] Specifically, the rotary drive component 321 drives the cam 325 to continue rotating, flipping the flipping component 3242 from the cam slide rail 3252 to the cam groove 3251, and the flipping component 3242 resets, completing the reset of the second bending assembly; the vertical drive component 311 drives the moving plate 313 to move away from the product 100 and return to the initial position, completing the reset of the first bending assembly.
