Abstract
Description
Technical Field
[0001] This application relates to the field of processing and manufacturing technology, and more specifically, to a bending device and a bending system thereof. Background Technology
[0002] When processing and manufacturing target components (such as chips, electronic components, etc.), one of the processes is to bend the metal parts of the target component (for example, bending the chip pins, bending the pins of electronic components, and bending certain metal connecting wires, etc.). The bending accuracy directly affects the quality of the connection between the target component and the external circuit.
[0003] However, most current metal bending devices for target parts adopt one-piece forming devices. These one-piece forming bending devices ignore the stress concentration generated at the bending point of the target part, resulting in low bending accuracy. This leads to an increase in the time step of subsequent processes such as wire bonding, ultimately reducing the processing efficiency of the target part. Utility Model Content
[0004] The purpose of this application is to provide a bending device and a bending system to solve the problem that current one-piece bending devices ignore stress concentration at the bending point of the target part, resulting in low bending accuracy and reduced processing efficiency of the target part in the later stage.
[0005] In a first aspect, this utility model provides a bending device, comprising: a die-casting unit, a transmission unit, and a target part receiving unit; the target part receiving unit is connected to a first end of the transmission unit, and the die-casting unit is disposed at the opposite end of the first end of the transmission unit; wherein, the first surface of the die-casting unit is opposite to the first surface of the target part receiving unit; at least one die-casting component is disposed on the first surface of the die-casting unit, and at least one receiving component is formed on the first surface of the target part receiving unit; wherein, the receiving component is used to receive the target part, and each die-casting component corresponds to one receiving component; the transmission unit is used to drive the die-casting unit to move until the first surface of the die-casting unit is in contact with the first surface of the target part receiving unit; wherein, in the contacted state, the die-casting component contacts and applies pressure to the portion of the target part to be bent corresponding to the receiving component.
[0006] The bending device designed above uses a transmission unit to drive the die-casting unit to fit and die-cast the target part receiving unit. This allows the die-casting components on the die-casting unit to contact and apply pressure to the part of the target part to be bent on the target receiving unit, thereby achieving pre-bending of the part to be bent. This reduces stress concentration when the part to be bent is directly bent, reduces the impact of bending accuracy on subsequent processes, and indirectly improves production efficiency.
[0007] In an alternative embodiment of the first aspect, the target component receiving unit includes a fixing plate and a receiving plate; the fixing plate is fixedly connected to the first end of the transmission unit, the receiving plate is detachably connected to the fixing plate, and at least one receiving component is disposed on the first surface of the receiving plate.
[0008] In an optional embodiment of the first aspect, a plurality of positioning studs are provided on the fixing plate; a plurality of positioning screw holes corresponding to the positioning studs are provided on the receiving plate, and the fixing plate and the receiving plate are detachably connected through the positioning studs and positioning screw holes.
[0009] In the above implementation, the fixed plate is fixedly connected to the first end of the transmission unit, while the receiving plate for placing the target part is detachably connected to the fixed plate. This not only makes it easier to remove the receiving plate, thus making the installation of the target part more convenient, but also makes it easier to replace the receiving plate of different specifications to adapt to different types of target parts, thereby reducing production costs.
[0010] In an optional embodiment of the first aspect, the receiving assembly includes a receiving groove, a receiving protrusion, and a receiving inner groove; the receiving inner groove is distributed on both sides of the receiving groove, and the receiving protrusion is disposed between the receiving inner groove and the receiving groove; the receiving groove is used to receive the target part, and the receiving protrusion and the receiving inner groove are used to place the bending portion of the target part.
[0011] In an optional embodiment of the first aspect, the die-casting assembly includes a die-casting groove, a die-casting protrusion, and a die-casting inner groove; the die-casting protrusion is distributed on both sides of the die-casting groove, and the die-casting inner groove is disposed between the die-casting protrusion and the die-casting groove; wherein the die-casting groove is opposite to the receiving groove, the die-casting inner groove is opposite to the receiving protrusion, and the die-casting protrusion is opposite to the receiving inner groove.
[0012] In the above-described implementation, this solution achieves die-casting bending of the part to be bent by the cooperation between the die-casting inner groove and the receiving protrusion, and the cooperation between the die-casting protrusion and the receiving inner groove. Furthermore, the cooperation between the die-casting groove and the receiving groove ensures that no pressure is applied to the body of the target part during the die-casting process, thereby improving the reliability and accuracy of die-casting.
[0013] In an alternative embodiment of the first aspect, a flexible element is provided inside the die-casting tank.
[0014] In the above-described implementation, this solution protects the target part from damage by providing a flexible component inside the die-casting tank and using the buffering effect of the flexible component.
[0015] In an optional embodiment of the first aspect, an installation cavity is provided in the receiving groove, and the target part receiving unit further includes a compensation block and an elastic member; one end of the elastic member is fixedly disposed in the installation cavity, and the other end of the elastic member is connected to the compensation block; wherein, the height of the compensation block is the same as the height of the receiving groove, and the compensation block is used to place the target part.
[0016] In the above-described embodiments, the compensation block, elastic element, and receiving groove designed in this solution cooperate to enable the bending device designed in this solution to bend the part to be bent on target parts of different sizes (e.g., to bend the metal pins of chips of different sizes), and can also change the stress concentration point of bending, and can also provide die-casting protection for the target parts, thereby improving the adaptability, reliability and bending accuracy of the bending device designed in this solution.
[0017] In an alternative embodiment of the first aspect, the depth of the receiving groove is greater than the depth of the receiving inner groove.
[0018] In the above-described embodiment, the depth of the receiving groove is greater than the depth of the receiving inner groove. This ensures that when the die-casting protrusion die-casts the part to be bent of the target part into the receiving inner groove, the die-casting assembly will not continue to move and press down, thereby protecting the target part from damage.
[0019] In an optional embodiment of the first aspect, there are multiple die-casting components and multiple receiving components, and the number of die-casting components and receiving components is the same, with the multiple die-casting components and multiple receiving components arranged in an array.
[0020] In the above-described embodiments, this solution designs multiple die-casting components and multiple receiving components arranged in an array, enabling the bending device designed in this solution to perform die-casting bending on the bending portions of multiple target parts at one time, thereby improving the processing efficiency of the target parts.
[0021] Secondly, the present invention provides a bending system, which includes a bending device according to any optional embodiment of the first aspect and a control device, wherein the control device is electrically connected to the transmission device.
[0022] The bending system designed above, because it includes the bending device described above, uses a designed transmission unit to drive the die-casting unit to fit and die-cast the target part receiving unit. This allows the die-casting components on the die-casting unit to contact and apply pressure to the part of the target part to be bent on the target receiving unit, thereby achieving pre-bending of the part to be bent. This reduces stress concentration in the direct bending of the part to be bent, reduces the impact of bending accuracy on subsequent processes, and indirectly improves production efficiency. In addition, the control device of the bending system designed in this scheme can control the transmission unit, thereby improving the automation and efficiency of the bending device.

[0038] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.
[0039] When processing and manufacturing target components (such as chips, electronic components, etc.), one of the processes is to bend the metal parts of the target component (for example, bending the chip pins, bending the pins of electronic components, and bending certain metal connecting wires, etc.). The bending accuracy directly affects the quality of the connection between the target component and the external circuit.
[0040] However, most current metal bending devices for target parts adopt one-piece forming devices. These one-piece forming bending devices ignore the stress concentration generated at the bending point of the target part, resulting in low bending accuracy. This leads to an increase in the time step of subsequent processes such as wire bonding, ultimately reducing the processing efficiency of the target part.
[0041] Based on the above problems, this application designs a bending device and its bending system. The designed transmission unit drives the die-casting unit to fit and die-cast with the target part receiving unit, so that the die-casting components on the die-casting unit contact and apply pressure to the part of the target part to be bent on the target receiving unit, thereby realizing the pre-bending of the part to be bent, thereby reducing the stress concentration of the part to be bent when directly bending it, reducing the impact of bending accuracy on subsequent processes, and indirectly improving production efficiency.
[0042] Based on the above ideas, this application first provides a bending device, such as... Figure 1 As shown, the bending device includes a die-casting unit 10, a transmission unit 20, and a target part receiving unit 30. The target part receiving unit 30 is connected to the first end of the transmission unit 20. The die-casting unit 10 is disposed at the opposite end of the first end of the transmission unit 20, and the first surface of the die-casting unit 10 is opposite to the first surface of the target part receiving unit 30.
[0043] In this design, at least one die-casting component 110 is provided on the first surface of the die-casting unit 10, and at least one receiving component 310 is provided on the first surface of the target part receiving unit 30. The receiving component 310 can accommodate the target part, and each die-casting component 110 corresponds to a receiving component 310.
[0044] The bending device designed above, in which the transmission unit 20 can drive the die-casting unit 10 to move, so that the die-casting unit 10 is close to the target part receiving unit 30 (e.g., Figure 1 The die-casting unit 10 moves downwards, causing its first surface to align with the first surface of the target component receiving unit 30. This aligns the die-casting component 110 on the die-casting unit 10 with the corresponding receiving component 310. In this aligned state, the die-casting component 110 contacts and applies pressure to the portion of the target component to be bent within the corresponding receiving component 310. The target component can be a chip, electronic component, or other metal connector. For example, if the target component is a chip, the portion to be bent represents the chip's metal pins. With the die-casting unit 10 aligned with the target component receiving unit 30, the die-casting component 110 contacts and applies pressure to the chip's metal pins, thus pre-bending them. This reduces stress concentration from direct bending of the chip's metal pins, lowers the impact of bending accuracy on subsequent processes, and indirectly improves production efficiency.
[0045] The bending device designed above uses a transmission unit to drive the die-casting unit to fit and die-cast the target part receiving unit. This allows the die-casting components on the die-casting unit to contact and apply pressure to the part of the target part to be bent on the target receiving unit, thereby achieving pre-bending of the part to be bent. This reduces stress concentration when the part to be bent is directly bent, reduces the impact of bending accuracy on subsequent processes, and indirectly improves production efficiency.
[0046] In an optional implementation of this embodiment, such as Figure 2 As shown, the target component accommodating unit 30 designed in this scheme may include a fixing plate 320 and an accommodating plate 330. The fixing plate 320 is fixedly connected to the first end of the transmission unit 20, and the accommodating plate 330 is detachably connected to the fixing plate 320. At least one accommodating component 310 is disposed on the first surface of the accommodating plate 330. Specifically, the fixing plate 320 is provided with a plurality of positioning studs 3210 (not shown in the figure), and the accommodating plate 330 is provided with a plurality of positioning screw holes 3310 corresponding to the positioning studs 3210 (not shown in the figure). The fixing plate 320 and the accommodating plate 330 are detachably connected through the positioning studs 3210 (not shown in the figure) and the positioning screw holes 3310.
[0047] In the above-described implementation, when the target part needs to be replaced or a target part of a different specification needs to be bent after one bend, this solution can loosen the positioning stud 3210 on the fixing plate 320, remove the original target part on the receiving plate 330 and replace it with a new target part, or directly replace the receiving plate 330 with a new target part, and then retighten the positioning stud 3210 to continue the next set of target part bending operations.
[0048] In the target component housing unit 30 designed above, the fixing plate 320 is fixedly connected to the first end of the transmission unit 20, while the housing plate 330 for placing the target component is detachably connected to the fixing plate 320. This not only makes it easier to remove the housing plate, thus making the installation of the target component more convenient, but also makes it easier to replace housing plates of different specifications to adapt to different types of target components, thereby reducing production costs.
[0049] In an optional implementation of this embodiment, as one possible implementation, such as Figure 3 This is a schematic diagram showing the distribution of die-casting components 110 and the structure of a single die-casting component, as shown below. Figure 4 This diagram illustrates the distribution of the accommodating components and the structure of a single accommodating component. To improve die-casting efficiency, this design allows for multiple die-casting components 110 and accommodating components 310, with the same number of each. The multiple die-casting components 110 and multiple accommodating components 310 can be arranged as follows: Figure 3 The array shown has each die-casting component 110 corresponding to a receiving component 310. Different die-casting components 110 correspond to different receiving components 310. In this way, the bending device designed in this scheme can perform die-casting bending on the bending parts of multiple target parts at one time, thereby further improving the processing efficiency of the target parts.
[0050] In an optional implementation of this embodiment, such as Figure 3 and Figure 4 As shown, each receiving component 310 and each die-casting component 110 in this design can be implemented in the following ways:
[0051] The receiving assembly 310 may include a receiving groove 3110, a receiving protrusion 3120, and a receiving inner groove 3130. The receiving inner groove 3130 is distributed on both sides of the receiving groove 3110, and the receiving protrusion 3120 is disposed between the receiving inner groove 3130 and the receiving groove 3110. Correspondingly, the die-casting assembly 110 designed in this scheme to cooperate with the receiving assembly 310 may include a die-casting groove 1110, a die-casting protrusion 1120, and The die-casting inner groove 1130 and the die-casting protrusions 1120 are distributed on both sides of the die-casting groove 1110, and the die-casting inner groove 1130 is disposed between the die-casting protrusions 1120 and the die-casting groove 1110; wherein, the die-casting groove 1110 of the die-casting component 110 is opposite to the receiving groove 3110 of the receiving component 310, the die-casting inner groove 1130 is opposite to the receiving protrusion 3120, and the die-casting protrusion 1120 is opposite to the receiving inner groove 3130.
[0052] As one possible implementation, both the die-casting component 110 and the receiving component 310 designed in this scheme can be as follows: Figure 3As shown in the centrally symmetrical structure, the internal horizontal height of the die-casting component 110 increases from both sides of the die-casting groove 1110, while the internal horizontal height of the receiving component 310 decreases from both sides of the receiving groove 3110. In this design, both the die-casting inner groove 1130 and the receiving inner groove 3130 can be triangular inner grooves, and both the die-casting protrusion 1120 and the receiving protrusion 3120 can be triangular protrusions, thereby increasing the pressure on the bending portion of the target part.
[0053] The aforementioned accommodating and die-casting components include an accommodating groove 3110 for accommodating a target component (e.g., a chip), and an accommodating protrusion 3120 and an accommodating inner groove 3130 for placing the portion of the target component to be bent (e.g., the metal pins of the chip). When the die-casting unit 10 is in contact with the target component accommodating unit 30, the die-casting protrusion 1120 die-casts the portion of the target component to be bent into the accommodating inner groove 3130, thereby enabling the portion of the target component to be bent to be bent. Simultaneously, since the chip is placed within the accommodating groove 3110, and the die-casting groove 1110 and the accommodating groove 3110 are recessed, pressure is avoided on the target component body (e.g., the chip body) during the die-casting process, thus preventing chip damage.
[0054] In an optional implementation of this embodiment, to further protect the target component, such as... Figure 3 As shown, the die-casting tank 1110 designed in this scheme can be equipped with a flexible component 11110. The flexible component 11110 includes, but is not limited to, flexible media such as rubber and silicone. Of course, other types of flexible media, such as sponge, can also be used. In this way, assuming that the die-casting tank 1110 makes contact with the chip in the receiving tank 3110 during the die-casting process, the target part can be protected from damage as much as possible through the buffering of the flexible component 11110.
[0055] In an optional embodiment of this invention, in order to further protect the target part, the depth of the receiving groove 3110 designed in this solution can be greater than the depth of the receiving inner groove 3130. Since the depth of the receiving inner groove 3130 is less than the depth of the receiving groove 3110, when the die-casting protrusion 1120 die-casts the part to be bent of the target part into the receiving inner groove 3130, the die-casting assembly 110 will not continue to move and press down, thereby ensuring that the die-casting unit 10 will not move and press down further, thus protecting the target part from damage.
[0056] In an optional embodiment of this example, since different target components have different sizes, in order to further protect the target components, such as... Figure 5As shown, the receiving groove 3110 of this design can also have an installation cavity 31110. The target component receiving unit 30 can also include a compensation block 340 and an elastic element 350. One end of the elastic element 350 is fixedly disposed in the installation cavity 31110, and the other end of the elastic element 350 is connected to the compensation block 340. The height of the compensation block 340 in this design is the same as the height of the receiving groove 3110. Specifically, the elastic element 350 in this design can be a spring or other medium with elastic properties, and the compensation block 340 in this design can be a metal block or a rubber block, etc.
[0057] In the above embodiment, the target part can be placed on the compensation block 340. When the target part is placed on the compensation block 340, the elastic member 350 will compress appropriately according to the weight of the target part, so that the target part can be placed stably in the receiving groove. At the same time, if the size of the target part is large, so that the height of the target part exceeds the depth of the receiving groove 3110, the die casting groove 1110 will inevitably come into contact with the target part. In the case of contact, the force on the target part will be transmitted to the elastic member 350 through the compensation block 340, so that the elastic member 350 is compressed, thereby avoiding damage to the die casting of the target part.
[0058] In the above-described embodiments, the compensation block, elastic element, and receiving groove 3110 designed in this scheme cooperate to enable the bending device designed in this scheme to bend the part to be bent on target parts of different sizes (for example, to bend the metal pins of chips of different sizes), and can also change the stress concentration point of bending, and can also provide die-casting protection for the target parts, thereby improving the adaptability, reliability and bending accuracy of the bending device designed in this scheme.
[0059] In an optional embodiment of this scheme, the transmission unit 20 designed in this scheme can specifically be a telescopic rod. The fixing plate 320 of the target part accommodating unit 30 is fixedly disposed on the first end of the telescopic rod, the accommodating plate 330 is disposed on the fixing plate 320, and the die-casting unit 10 is disposed on the second end of the telescopic rod. The telescopic rod can drive the die-casting unit 10 to move towards the accommodating plate 330 by contraction, thereby making the die-casting unit 10 fit against the accommodating plate 330. Specifically, the telescopic rod designed in this scheme can be any one of a hydraulic telescopic rod, a pneumatic telescopic rod, or an electric telescopic rod. Taking a hydraulic telescopic rod as an example, the end of the cylinder of the hydraulic telescopic rod can be flush with or lower than the height of the accommodating plate 330. In this way, after the piston rod contracts and drives the die-casting unit 10 to move, whether the piston rod is fully contracted or not, the die-casting unit 10 can fit against the accommodating plate 330.
[0060] It should be noted that, in addition to telescopic rods, the transmission unit 20 designed in this scheme can also use other types of transmission devices, as long as the die-casting unit 10 can be attached to the receiving plate 330. For example, a transmission device composed of gears and racks.
[0061] This application also provides a bending system, such as Figure 6 As shown, the bending system may include a bending device 1 and a control device 2 according to any optional embodiment of the first aspect, wherein the control device 2 is electrically connected to the transmission unit 20.
[0062] In the bending system designed above, the control device 2 is electrically connected to the transmission unit 20. This allows the control device 2 to control the movement or stop of the transmission unit 20, thereby achieving an automated bending process. Specifically, the transmission unit 20 in this design can be an electric telescopic rod, and the control device 2 can be a controller, host computer, control chip, computer, etc. The control device 2 can send control signals to the motor of the electric telescopic rod to control its extension and retraction. Furthermore, when the electric telescopic rod drives the die-casting unit 10 to fit against the receiving plate 330, the control device 2 stops the extension and retraction of the electric telescopic rod, thus achieving automatic bending control.
[0063] The bending system designed above, because it includes the bending device described above, uses a designed transmission unit to drive the die-casting unit to fit and die-cast the target part receiving unit. This allows the die-casting components on the die-casting unit to contact and apply pressure to the part of the target part to be bent on the target receiving unit, thereby achieving pre-bending of the part to be bent. This reduces stress concentration in the direct bending of the part to be bent, reduces the impact of bending accuracy on subsequent processes, and indirectly improves production efficiency. In addition, the control device of the bending system designed in this scheme can control the transmission unit, thereby improving the automation and efficiency of the bending device.
[0064] In an optional embodiment of this solution, a position sensor (e.g., a photoelectric sensor or a proximity sensor) can be used to detect the position of the die-casting unit 10 and the receiving plate 330. When the die-casting unit 10 approaches the receiving plate 330, the sensor sends a signal to the control device 2. The control device 2 can adjust the movement speed of the electric telescopic rod according to the signal, thereby achieving a smooth fit between the die-casting unit 10 and the receiving plate 330. Furthermore, for cases requiring precise fit, this solution can also incorporate a pressure sensor to monitor the fit pressure in real time during the fit process between the die-casting unit 10 and the receiving plate 330. When the pressure reaches a set value, the movement of the electric telescopic rod is stopped to ensure that the fit meets the requirements.
[0065] In the above-described embodiments, the position sensor and pressure sensor designed in this scheme can achieve a smooth fit between the die-casting unit 10 and the receiving plate 330, thereby improving the accuracy and reliability of the die-casting bending process.
