Description

Technical Field

[0001] This invention relates to the field of die bonder technology, and particularly to a material suction device assembly and a die bonder. Background Technology

[0002] With the development of industrial technology, die bonders are rapidly evolving towards high automation to improve production efficiency. Existing die bonders mostly use nozzles to pick up, transfer, and press the chips. Frequent contact inevitably leads to wear and tear. In addition, some circuit boards have complex designs and are difficult to position. Often, it is necessary to position the chips on the worktable once to complete the die bonding of the entire circuit board. Because the chips on a circuit board are of different sizes, it is necessary to change different types of nozzles multiple times to complete the task.

[0003] However, existing suction device combinations and nozzle holders are prone to damaging the nozzles when changing nozzles. Summary of the Invention

[0004] To address the problem of nozzle damage during nozzle replacement in existing suction device assemblies, this invention provides a suction device assembly and a die bonder.

[0005] The present invention provides a suction device assembly, comprising a suction nozzle, a binding head, and a suction nozzle frame. The suction nozzle frame includes at least one support platform for placing the suction nozzle, a connecting seat, and an elastic element connecting the support platform and the connecting seat. The support platform includes a bearing surface and has a receiving groove in the direction perpendicular to the bearing surface to hold the suction nozzle. The connecting seat is connected to an external device. When the binding head is used to install the suction nozzle, the binding head moves to the corresponding suction nozzle position and moves in the direction perpendicular to the bearing surface to install the suction nozzle. The elastic element allows the support platform to move elastically in a direction parallel to the bearing surface. The suction nozzle includes interconnected connecting parts. The connector and the suction part are provided. The surface of the connector away from the suction part is parabolic or spherical. The elastic element is a spring sheet. The connector and the support platform are respectively provided with insertion gaps. The elastic element is inserted into the insertion gaps between the connector and the support platform. Vertical elastic material is provided at both ends of the insertion gaps and / or the elastic element. The binding head includes a connecting air extraction section and an adapter section. The receiving cavity is provided in the adapter section and its shape is adapted to the shape of the connector. The air extraction section has an air extraction chamber communicating with the receiving cavity. The air extraction section and the adapter section are respectively provided with air extraction holes communicating with the air extraction chamber and the receiving cavity.

[0006] Preferably, the suction part includes two opposite ends, one end of which is connected to the connecting part, and the other end has a suction hole that penetrates the connecting part and the suction part.

[0007] Preferably, the suction section comprises interconnected frustum, cylindrical, and conical sections from near the connecting section to far from the connecting section, and the cross-sectional dimensions gradually decrease.

[0008] Preferably, the support platform is provided with a positioning element, and the receiving groove and the positioning element are arranged at a fixed interval on the support surface.

[0009] Preferably, the suction part is a combination of a frustum, a cylinder, and a cone, and the receiving groove is a cavity with a frustum and a cylinder structure, in which the suction part is housed.

[0010] Preferably, the connecting part is provided with a code representing the nozzle model, and the bearing surface near the edge of the receiving groove is provided with a code representing the receiving groove model.

[0011] Preferably, the connector has two perpendicular insertion slots.

[0012] To solve the above-mentioned technical problems, the present invention also provides a die bonder, which includes the above-mentioned material suction device combination.

[0013] Compared with the prior art, the material feeding device assembly and die bonder of the present invention have the following advantages:

[0014] 1. The suction device assembly of the present invention includes a suction nozzle, a binding head, and a suction nozzle frame. The suction nozzle frame includes at least one support platform for placing the suction nozzle, a connecting seat, and an elastic element connecting the support platform and the connecting seat. The support platform includes a bearing surface and has a receiving groove in the direction perpendicular to the bearing surface to hold the suction nozzle. The connecting seat is connected to an external device. When the binding head is used to install the suction nozzle, the binding head moves to the corresponding suction nozzle position and moves in the direction perpendicular to the bearing surface to install the suction nozzle. The elastic element allows the support platform to move elastically in a direction parallel to the bearing surface. Through the cooperative design of the binding head, the suction nozzle, and the suction nozzle frame, the support platform can move when the suction nozzle is replaced, and the suction nozzle can be adapted to the binding head, solving the problem of the suction nozzle easily getting stuck or damaged when replacing the suction nozzle in the prior art.

[0015] 2. The suction nozzle of the suction device assembly of the present invention includes a connecting part and a suction part that are connected to each other. The surface of the connecting part away from the suction part is a parabolic or spherical surface. The suction part includes two opposing ends, one end of which is connected to the connecting part, and the other end has a suction hole that penetrates through the connecting part and the suction part. By designing the connecting part of the suction nozzle as a combination of a cylindrical surface and a parabolic or spherical surface, the friction between the suction nozzle and the mounting part is reduced, solving the problem that existing suction nozzles are prone to jamming and difficult to replace.

[0016] 3. The suction section of the suction nozzle in the suction device assembly of the present invention comprises interconnected frustum, cylindrical, and conical sections from near the connecting section to far from the connecting section, with the cross-sectional dimensions gradually decreasing. This design, where the frustum, cylindrical, and conical sections are interconnected and the cross-sectional dimensions gradually decrease, makes it less likely for the suction nozzle to get stuck, while simultaneously reducing the area at the suction opening and enhancing the unit suction force.

[0017] 4. The binding head of the suction device assembly of the present invention includes a connecting air extraction section and an adapter section. A receiving cavity is disposed in the adapter section, and its shape is adapted to the shape of the connecting part. The air extraction section has an air extraction chamber communicating with the receiving cavity. The air extraction section and the adapter section are respectively provided with air extraction holes communicating with the air extraction chamber and the receiving cavity. By designing the adapter section as a cavity adapted to the shape of the connecting part, the suction nozzle and the binding head fit more tightly, increasing airtightness and the suction force of the binding head on the suction nozzle, preventing the suction nozzle from falling off.

[0018] 5. The support platform of the suction device assembly of the present invention is provided with a positioning element, and the receiving groove and the positioning element are arranged at a fixed interval on the support surface. By designing the receiving groove and the positioning element to be arranged at a fixed interval, when changing the suction nozzle, the positioning element is positioned first, and then the receiving groove where the required suction nozzle is located is found by moving a fixed distance, which increases the efficiency of changing the suction nozzle.

[0019] 6. The suction device assembly of the present invention has a cavity with a frustum-cylinder structure, in which the suction part is housed. By designing the suction part of the nozzle and the cavity of the cavity to correspond in shape, the nozzle is less likely to get stuck when placed in the cavity, and it is easier to replace the nozzle.

[0020] 7. The connecting part of the suction device assembly of the present invention is provided with a code representing the model of the suction nozzle, and the bearing surface near the edge of the receiving groove is provided with a code representing the model of the receiving groove. By providing codes representing the model of the suction nozzle at the connecting part and the edge of the receiving groove, it is possible to quickly put the original suction nozzle back into the receiving groove and quickly locate the other required suction nozzle when changing the suction nozzle, thereby improving the efficiency of suction nozzle changing.

[0021] 8. The elastic element of the suction device assembly of the present invention is a sheet or a spring. By designing the elastic element as a sheet or a spring, the support platform can obtain a certain range of movement under the action of the elastic element, reducing the risk of nozzle damage when changing the nozzle and solving the problem of nozzle jamming or damage during nozzle replacement in the prior art.

[0022] 9. When the elastic element of the suction device assembly of the present invention is a spring sheet, a vertical elastic material is provided at the connection of the spring sheet to provide vertical cushioning. By providing the vertical elastic material, the support platform has the ability to move in the vertical direction, further increasing the mobility of the support platform and further protecting the safety of the suction nozzle.

[0023] 10. The present invention also provides a die bonder, which includes the above-described material suction device combination and has the same beneficial effects as the above-described material suction device combination, and will not be described in detail here. Attached Figure Description

[0056] Please see Figure 1 The first embodiment of this application provides a suction nozzle 1, including a connecting portion 10 and a suction portion 11 connected to each other. The connecting portion 10 is configured as a combination of a cylindrical surface and a parabolic or spherical surface; specifically, the surface at the end away from the suction portion 11 is a parabolic or spherical surface. The suction portion 11 includes two opposing ends, one end connected to the connecting portion 10, and the other end having a suction hole penetrating through the connecting portion 10 and the suction portion 11. By configuring the connecting portion 10 of the suction nozzle 1 as a combination of a cylindrical surface and a parabolic or spherical surface, the friction between the suction nozzle 1 and the mounting part is reduced, solving the problem of existing suction nozzles being prone to jamming and difficult to replace.

[0057] Furthermore, the suction part 11 is a combination of a frustum, a cylindrical surface, and a conical surface, and the suction part 11 and the connecting part 10 have cavities that match their shapes. By designing the suction part 11 as a combination of a frustum, a cylindrical surface, and a conical surface, the nozzle 1 is less likely to get stuck during storage, reducing damage to the nozzle.

[0058] Specifically, the suction section 11 includes interconnected frustum, cylindrical, and conical sections from near the connecting section 10 to far away from the connecting section 10, with the cross-sectional dimensions gradually decreasing. This design, where the frustum, cylindrical, and conical sections are interconnected and the cross-sectional dimensions gradually decrease, makes it less likely for the suction nozzle to get stuck, while also reducing the area at the suction opening and enhancing the unit suction force.

[0059] Preferably, the connecting part 10 further includes a cylindrical section connected to the suction part 11, wherein the maximum dimension of the frustum section of the suction part 11 matches the dimension of the cylindrical section of the connecting part 10. This design, where the maximum dimension of the frustum section of the suction part matches the maximum dimension of the cylindrical section of the connecting part, allows the suction nozzle to be fixed in place by the cylindrical and frustum sections, protecting the suction hole from wear.

[0060] Specifically, the connecting part 10 and the suction part 11 are integrally formed. The design of the connecting part 10 and the suction part 11 being integrally formed increases the strength of the overall structure of the nozzle and increases the airtightness of the nozzle 1, thereby increasing the suction force of the nozzle 1.

[0061] Please see Figure 2 The connecting part 10 is provided with a code 101 representing the nozzle model. By setting the code 101, the required nozzle model can be identified and located more quickly when changing nozzles, thus increasing the efficiency of use.

[0062] Please see Figure 3 The second embodiment of this application provides a suction device 2, including a suction nozzle 1 and a binding head 20 that cooperates with the suction nozzle.

[0063] For details, please continue reading Figure 3 The head strap 20 has a receiving cavity 201 adapted to the nozzle 1, and the connecting part 10 of the nozzle 1 is installed in the receiving cavity 201. The design of the receiving cavity 201 adapted to the nozzle 1 by the head strap 20 makes the nozzle 1 fit more tightly with the head strap 20, increases the airtightness and the suction force of the head strap 20 on the nozzle, and prevents the nozzle from falling off.

[0064] For more details, please refer to Figure 4 The binding head 20 includes a connected suction section 202 and an adapter section 203. The adapter section 203 has a cavity—a receiving cavity 201—that matches the shape of the connecting part 10. The suction section 202 has a suction chamber 204, and the receiving cavity 201 and the suction chamber 204 are connected. The suction section 202 and the adapter section 203 each have at least one suction hole 205 that communicates with the receiving cavity 201 and the suction chamber 204, respectively. When the binding head 20 is connected to the suction nozzle 1, the suction hole of the suction nozzle 1 communicates with the receiving cavity 201. Through the adapter section 203 connected to the suction nozzle 1, the suction section 202 aligns with the suction hole of the suction nozzle 1, and the suction hole 205 of the adapter section 203 holds the suction nozzle in place. The suction hole 205 of the suction section 202 generates suction to pick up products such as chips, thereby achieving the function of installing chips.

[0065] Furthermore, the adapter section 203 has two suction holes 205 that are symmetrically arranged. By symmetrically arranging the two suction holes 205, the bidirectional suction force is more balanced, avoiding slight tilting of the nozzle 1 due to unidirectional suction force, thereby improving the accuracy of nozzle adsorption.

[0066] Further, please refer to Figure 5 The binding head 20 also includes a suction pipe 206, which is correspondingly provided with a suction port 205. By providing a suction pipe, it is easy to connect to the hose of an external vacuum device, thus enhancing its practicality.

[0067] Please combine Figure 6 and Figure 7 The third embodiment of this application provides a die bonder 700, including the aforementioned suction nozzle 1; or a die bonder 710, which includes the aforementioned material suction device 2.

[0068] Please see Figure 8 The fourth embodiment of this application provides a nozzle holder 3, including at least one support platform 30 for placing a nozzle 1. The support platform 30 defines a support surface 33, and at least one receiving groove 301 is formed in the direction perpendicular to the support surface 33 to accommodate the nozzle 1. The nozzle 1 is placed perpendicular to the support surface 33 of the support platform 30; a connecting seat 31, which is connected to an external device; and at least one elastic member 32, which is connected to both the connecting seat 31 and the support platform 30. The elastic member 32 allows the support platform 30 to move elastically in a direction parallel to the support surface 33. By providing the elastic member 32 to allow the support platform 30 to move elastically in a direction parallel to the support surface 33, the nozzle holder 3 is given a certain amount of room for movement, making nozzle replacement safer and solving the problem of nozzles easily getting stuck or damaged when replacing nozzles in the prior art.

[0069] Optionally, the elastic element 32 can be a sheet or a spring.

[0070] Specifically, please refer to Figure 9 In the fourth embodiment of this application, the elastic element 32 is a spring sheet, and the connecting seat 31 and the support platform 30 are respectively provided with insertion gaps 34. By designing the elastic element 32 as a spring sheet, the elastic element 32 is inserted into the insertion gap 34 between the connecting seat 31 and the support platform 30, so that the support platform 30 can move elastically on a plane perpendicular to the spring sheet, which solves the problem of the suction nozzle easily getting stuck or damaged when changing the suction nozzle in the prior art.

[0071] In a variation of the fourth embodiment of this application, the elastic element 32 is a spring, and the connecting seat 31 and the support platform 30 are respectively provided with mounting holes 35 (not shown). When the elastic element is set as a spring, the support platform 30 can move not only on the plane parallel to the bearing surface 33, but also in the vertical direction, further increasing the mobility of the support platform 30 and solving the problem that the suction nozzle is easily stuck or damaged when changing the suction nozzle in the prior art.

[0072] Furthermore, vertical elastic material is provided at both ends of the insertion gap 34 and / or the elastic element 32 to provide vertical cushioning. This design, with the vertical elastic material, allows the support platform 30 to move vertically, further increasing its mobility and protecting the nozzle's safety.

[0073] For details, please continue reading Figure 9The connector 31 is provided with two mutually perpendicular insertion slots 34. By providing two mutually perpendicular insertion slots, the elastic element 32 can be set in both the horizontal and vertical directions, which makes the application scenarios more extensive and increases its applicability.

[0074] For further information, please refer to [link / reference]. Figure 9 The support platform 30 is equipped with a positioning element 302, and the receiving groove 301 and the positioning element 302 are arranged at a fixed interval on the support surface 33. By designing the receiving groove 301 and the positioning element 302 at a fixed interval, when changing the suction nozzle, the positioning element 302 is positioned first, and then the receiving groove 301 where the required suction nozzle is located is found by moving a fixed distance, which increases the efficiency of changing the suction nozzle.

[0075] Understandably, the receiving groove 301 can be arranged in multiple rows or columns, and the positioning element 302 can also be arranged in multiple ways. Any simple changes in the arrangement order are within the scope of protection of this application.

[0076] For further information, please refer to [link / reference]. Figure 9 The bearing surface 33 is provided with a code 303 representing the model of the receiving groove 301 near the edge of the receiving groove 301. By setting the code 303, the wrong nozzle will not be replaced due to error when replacing the nozzle, thus improving the accuracy and efficiency of nozzle replacement.

[0077] For further information, please refer to [link / reference]. Figure 9 The receiving groove 301 is a cavity with a frustum-cylinder structure. The groove opening size near the bearing surface 33 is larger than the groove bottom size away from the bearing surface 33. By designing the receiving groove 301 as a cavity with a frustum-cylinder structure, it is adapted to the suction part 11 of the suction nozzle, making it less likely to get stuck when the suction nozzle is placed in the receiving groove, and making it easier to replace the suction nozzle.

[0078] Specifically, the positioning element 302 is set on the center line of the cylinder of the receiving groove 301. By setting the positioning element 302 on the center line, when changing the nozzle, the positioning element 302 is first located and moved on the center line to find the required receiving groove 301, thereby improving the compatibility between the nozzle installation device and the nozzle, thus improving the installation efficiency of the nozzle and reducing the probability of the nozzle being crushed or stuck.

[0079] Please see Figure 10 The fifth embodiment of this application provides a die bonder 800, which includes the above-described nozzle holder 3.

[0080] Please see Figure 11The sixth embodiment of this application provides a suction device assembly 500, including a suction nozzle 1, a binding head 20, and a suction nozzle frame 3. The suction nozzle frame 3 includes at least one support platform 30 for placing the suction nozzle, a connecting seat 31, and an elastic member 32 connecting the support platform 30 and the connecting seat 31. The support platform 30 includes a support surface 33 and has a receiving groove 301 in the direction perpendicular to the support surface 33 to hold the suction nozzle 1. The suction nozzle 1 is placed perpendicular to the support surface 33 of the support platform 30. The connecting seat 31 is connected to an external device. The elastic member 32 is connected to the connecting seat 31 and the support platform 30 respectively. When the binding head 20 is used to install the suction nozzle 1, the binding head 20 moves to the corresponding suction nozzle 1 and moves in the direction perpendicular to the support surface 33 to install the suction nozzle 1. The elastic member 32 allows the support platform 30 to move elastically in the direction parallel to the support surface 33. The design of the binding head 20, the suction nozzle 1, and the suction nozzle holder 3 allows the support platform 30 to move when the suction nozzle 1 is replaced, and the suction nozzle 1 can be adapted to the binding head 20, thus solving the problem that the suction nozzle is easily stuck or damaged when replacing the suction nozzle in the prior art.

[0081] During operation, different types of suction nozzles 1 are placed in the corresponding receiving grooves 301. The shape of the suction part 11 is adapted to the shape of the receiving groove 301. The binding head 20 moves a fixed distance from the positioning part 302 and locks the required type of suction nozzle 1. When the binding head 20 moves to the designated position, the fitting section 203 connects with the connecting part 10. At the same time, the elastic part 32 provides tolerance for deviations caused by movement to prevent damage to the suction nozzle 1.

[0082] Please see Figure 12 To solve the above-mentioned technical problems, the present invention also provides a die bonder 900, which includes the above-mentioned material suction device assembly 500.

[0083] Compared with the prior art, the material feeding device assembly and die bonder of the present invention have the following advantages:

[0084] 1. The suction device assembly of the present invention includes a suction nozzle, a binding head, and a suction nozzle frame. The suction nozzle frame includes at least one support platform for placing the suction nozzle, a connecting seat, and an elastic element connecting the support platform and the connecting seat. The support platform includes a bearing surface and has a receiving groove in the direction perpendicular to the bearing surface to hold the suction nozzle. The connecting seat is connected to an external device. When the binding head is used to install the suction nozzle, the binding head moves to the corresponding suction nozzle position and moves in the direction perpendicular to the bearing surface to install the suction nozzle. The elastic element allows the support platform to move elastically in a direction parallel to the bearing surface. Through the cooperative design of the binding head, the suction nozzle, and the suction nozzle frame, the support platform can move when the suction nozzle is replaced, and the suction nozzle can be adapted to the binding head, solving the problem of the suction nozzle easily getting stuck or damaged when replacing the suction nozzle in the prior art.

[0085] 2. The suction nozzle of the suction device assembly of the present invention includes a connecting part and a suction part that are connected to each other. The surface of the connecting part away from the suction part is a parabolic or spherical surface. The suction part includes two opposing ends, one end of which is connected to the connecting part, and the other end has a suction hole that penetrates through the connecting part and the suction part. By designing the connecting part of the suction nozzle as a combination of a cylindrical surface and a parabolic or spherical surface, the friction between the suction nozzle and the mounting part is reduced, solving the problem that existing suction nozzles are prone to jamming and difficult to replace.

[0086] 3. The suction section of the suction nozzle in the suction device assembly of the present invention comprises interconnected frustum, cylindrical, and conical sections from near the connecting section to far from the connecting section, with the cross-sectional dimensions gradually decreasing. This design, where the frustum, cylindrical, and conical sections are interconnected and the cross-sectional dimensions gradually decrease, makes it less likely for the suction nozzle to get stuck, while simultaneously reducing the area at the suction opening and enhancing the unit suction force.

[0087] 4. The binding head of the suction device assembly of the present invention includes a connecting air extraction section and an adapter section. A receiving cavity is disposed in the adapter section, and its shape is adapted to the shape of the connecting part. The air extraction section has an air extraction chamber communicating with the receiving cavity. The air extraction section and the adapter section are respectively provided with air extraction holes communicating with the air extraction chamber and the receiving cavity. By designing the adapter section as a cavity adapted to the shape of the connecting part, the suction nozzle and the binding head fit more tightly, increasing airtightness and the suction force of the binding head on the suction nozzle, preventing the suction nozzle from falling off.

[0088] 5. The support platform of the suction device assembly of the present invention is provided with a positioning element, and the receiving groove and the positioning element are arranged at a fixed interval on the support surface. By designing the receiving groove and the positioning element to be arranged at a fixed interval, when changing the suction nozzle, the positioning element is positioned first, and then the receiving groove where the required suction nozzle is located is found by moving a fixed distance, which increases the efficiency of changing the suction nozzle.

[0089] 6. The suction device assembly of the present invention has a cavity with a frustum-cylinder structure, in which the suction part is housed. By designing the suction part of the nozzle and the cavity of the cavity to correspond in shape, the nozzle is less likely to get stuck when placed in the cavity, and it is easier to replace the nozzle.

[0090] 7. The connecting part of the suction device assembly of the present invention is provided with a code representing the model of the suction nozzle, and the bearing surface near the edge of the receiving groove is provided with a code representing the model of the receiving groove. By providing codes representing the model of the suction nozzle at the connecting part and the edge of the receiving groove, it is possible to quickly put the original suction nozzle back into the receiving groove and quickly locate the other required suction nozzle when changing the suction nozzle, thereby improving the efficiency of suction nozzle changing.

[0091] 8. The elastic element of the suction device assembly of the present invention is a sheet or a spring. By designing the elastic element as a sheet or a spring, the support platform can obtain a certain range of movement under the action of the elastic element, reducing the risk of nozzle damage when changing the nozzle and solving the problem of nozzle jamming or damage during nozzle replacement in the prior art.

[0092] 9. When the elastic element of the suction device assembly of the present invention is a spring sheet, a vertical elastic material is provided at the connection of the spring sheet to provide vertical cushioning. By providing the vertical elastic material, the support platform has the ability to move in the vertical direction, further increasing the mobility of the support platform and further protecting the safety of the suction nozzle.

[0093] 10. The present invention also provides a die bonder, which includes the above-described material suction device combination and has the same beneficial effects as the above-described material suction device combination, and will not be described in detail here.

[0094] The foregoing has provided a detailed description of a material suction device assembly and a die bonder disclosed in the embodiments of the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention.
