Description

Technical Field

[0001] This utility model belongs to the field of electronic equipment manufacturing technology, specifically relating to a pressure holding device and a chip mounting device. Background Technology

[0002] The manufacturing process of electronic devices involves a coating process, which forms a film on the surface of the product. To ensure product stability during coating, the product needs to be adhered to a fixture with adhesive (i.e., a coating plate) before coating to secure it. To ensure reliable adhesion between the product and the fixture and prevent the product from detaching from the fixture in subsequent processes, the product needs to be rolled. For products with high surface finish requirements, a protective film needs to be applied to one side of the product surface before rolling, and then removed after rolling. In existing processes, coating, rolling, and film removal all require manual operation.

[0003] In existing technologies, attaching products to fixtures is achieved through manual operation, which can easily lead to unreliable product adhesion and cause the product surface to become contaminated with dirt (such as grease, dust, etc.), affecting the quality of subsequent coating. Utility Model Content

[0004] To address the aforementioned defects or deficiencies, this utility model provides a pressure-holding device and a patch-mounting equipment, aiming to solve the technical problems of existing bonding processes relying on manual operation, which easily leads to unreliable product bonding and allows dirt to adhere to the product surface, affecting the quality of the coating.

[0005] To achieve the above objectives, the first aspect of this utility model provides a pressure-holding device, comprising: A platform, equipped with a bearing position for mounting a fixture, the fixture having a product bearing surface, and a through hole penetrating the fixture on the product bearing surface; and The negative pressure component is placed on the platform, with the adsorption end of the negative pressure component positioned at the end of the through hole furthest from the product's bearing surface.

[0006] In this embodiment of the utility model, a first base and a second base are respectively provided at both ends of the platform, and a bearing position is formed between the tops of the first base and the second base, with the negative pressure component located below the bearing position.

[0007] In this embodiment of the invention, the pressure-holding device further includes a fixture positioning mechanism disposed on the first base and / or the second base.

[0008] In this embodiment of the utility model, multiple sets of through holes are opened on the product bearing surface, and multiple negative pressure components are provided on the platform. The adsorption ends of the multiple negative pressure components are respectively set at the ends of the multiple sets of through holes away from the product bearing surface.

[0009] In this embodiment of the utility model, the negative pressure component includes a lifting drive mechanism and a suction cup assembly. The lifting drive mechanism is located on the platform and drives the suction cup assembly. The suction cups on the suction cup assembly form the adsorption end.

[0010] In this embodiment of the utility model, the suction cup assembly further includes a suction cup mounting plate, which has a contoured surface that is parallel to the bottom surface of the fixture, and the suction cup is disposed on the contoured surface.

[0011] In this embodiment of the utility model, the lifting drive mechanism includes a lifting drive cylinder, a mounting top plate, and a guide rod. The mounting top plate is disposed on the platform and has a piston rod through hole and a guide rod through hole. The cylinder of the lifting drive cylinder is connected to the lower plate surface of the mounting top plate. The piston rod of the lifting drive cylinder passes through the piston rod through hole and drives the suction cup assembly. The guide rod passes through the guide rod through hole and connects to the suction cup assembly.

[0012] The second aspect of this utility model provides a patch mounting device, comprising: Pressure holding device; A fixture, having a product-bearing surface, with a through hole extending through the fixture on the product-bearing surface, the fixture being detachably mounted on the bearing position; and Handling mechanisms are used to move products.

[0013] In this embodiment of the invention, the patch assembly equipment also includes a transfer mechanism, which drives the pressure holding device to move between the loading station and the unloading station.

[0014] In this embodiment of the invention, an adhesive layer is provided on the product bearing surface of the fixture.

[0015] Through the above technical solutions, the pressure holding device and patch assembly equipment provided by this utility model embodiment have the following beneficial effects: When using the aforementioned pressure-holding device, the fixture can be installed on the bearing position of the stage to keep it stable. Then, a stable negative pressure environment is formed in the through hole through the suction end on the negative pressure component corresponding to the through hole of the fixture. The product is firmly adsorbed onto the product bearing surface of the fixture by the air pressure difference. Compared with the existing bonding process, this pressure-holding device can eliminate the processes of film coating, rolling, and film peeling. Furthermore, the negative pressure component does not directly contact the product, avoiding the possibility of contamination and improving the coating quality.

[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0018] Explanation of reference numerals in the attached figures Detailed Implementation

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] The pressure holding device and patch mounting equipment of this utility model are described below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, the first aspect of this utility model provides a pressure-holding device, which includes a platform 100 and a negative pressure component 400.

[0022] The stage 100 is provided with a bearing position for mounting a fixture 200. The fixture 200 forms a product bearing surface, and a through hole 210 is provided on the product bearing surface. A negative pressure component 400 is provided on the stage 100. When the negative pressure component 400 is working, it is connected to an external negative pressure source (such as a vacuum pump). The adsorption end of the negative pressure component 400 is set at the end of the through hole 210 away from the product bearing surface.

[0023] When using the aforementioned pressure-holding device, the fixture 200 can be installed on the bearing position of the stage 100 to keep the fixture 200 stable. Then, a stable negative pressure environment is formed in the through hole 210 of the negative pressure component 400 corresponding to the through hole 210 of the fixture 200. The product 700 is firmly adsorbed onto the product bearing surface of the fixture 200 by the air pressure difference. Compared with the existing bonding process, the pressure-holding device can eliminate the processes of film coating, rolling, and film peeling. Furthermore, the negative pressure component 400 does not directly contact the product 700, avoiding the possibility of contamination of the product 700 and achieving the effect of improving the coating quality.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment of the present invention, a first base 110 and a second base 120 are respectively provided at both ends of the platform 100. A bearing position is formed between the tops of the first base 110 and the second base 120. The negative pressure component 400 is disposed between the first base 110 and the second base 120 and located below the bearing position. Thus, the first base 110 and the second base 120, while supporting the fixture 200, also form an installation space below the fixture 200 for accommodating the negative pressure component 400. This creates a layout with the fixture 200 on top and the negative pressure component 400 below, which facilitates the alignment of the suction end of the negative pressure component 400 with the through hole 210 and reduces the footprint of the pressure-holding device. Furthermore, compared to the embodiment where the negative pressure component 400 is placed on the side of the fixture 200, arranging the negative pressure component 400 below the fixture 200 avoids interference with the removal and placement of the fixture 200.

[0025] like Figure 1 As shown in this embodiment of the invention, the pressure-holding device further includes a fixture positioning mechanism 500 disposed on the first base 110 and the second base 120. After the fixture 200 is placed in the bearing position, the two gripper ends of the fixture positioning mechanism 500 are controlled to move closer together to clamp and position the fixture 200, ensuring the positional accuracy of the fixture 200 in the bearing position and avoiding misalignment between the negative pressure adsorption end and the through hole 210 due to the fixture 200 shifting, which would affect the pressure-holding effect.

[0026] Specifically, the fixture positioning mechanism 500 can be configured as a pneumatic gripper, which includes two gripping fingers as gripper ends. Furthermore, a rubber pad can be provided on the inner side of each gripping finger to reduce noise when clamping the fixture 200 and to prevent the fixture 200 from slipping during clamping.

[0027] It should be noted that, in order to ensure the reliability of clamping and positioning, the best implementation is to provide a fixture positioning mechanism 500 on both the first base 110 and the second base 120. However, in other embodiments, it is also possible to provide a fixture positioning mechanism 500 on only one of the first base 110 and the second base 120.

[0028] like Figure 1 and Figure 3 As shown in this embodiment of the utility model, multiple sets of through holes 210 are provided on the product bearing surface, and multiple negative pressure components 400 are provided on the platform 100. The adsorption ends of the multiple negative pressure components 400 are respectively set at the ends of the multiple sets of through holes 210 away from the product bearing surface, thereby realizing the fixation of multiple sets of products 700 and improving the production efficiency of products 700.

[0029] like Figure 2 and Figure 5 As shown in this embodiment of the invention, the negative pressure component 400 includes a lifting drive mechanism 410 and a suction cup assembly 420. The lifting drive mechanism 410 is mounted on the platform 100 and drives the suction cup assembly 420. The suction cups 422 on the suction cup assembly 420 form the adsorption end. When the product 700 needs to be adsorbed and fixed, the lifting drive mechanism 410 drives the suction cup assembly 420 to move upward, so that the suction cups 422 are tightly attached to the end of the through hole 210 away from the product bearing surface. When the product 700 needs to be released, the lifting drive mechanism 410 drives the suction cup assembly 420 to move downward, disengaging from the attachment state with the through hole 210. Thus, by setting the lifting drive mechanism 410, both the stability of adsorption is ensured and the operation of picking up and putting down the product 700 is facilitated.

[0030] like Figure 1 and Figure 5 As shown in this embodiment of the invention, the suction cup assembly 420 further includes a suction cup mounting plate 421. The suction cup mounting plate 421 has a contoured surface that is parallel to the bottom surface of the fixture 200, and the suction cup 422 is disposed on the contoured surface. The contoured design of the suction cup mounting plate 421 makes the fit between the suction cup assembly 420 and the fixture 200 tighter, reduces air leakage during the adsorption process, and enhances the effect of negative pressure adsorption.

[0031] Specifically, the fixture 200 includes a central support portion 220 and two side support portions 230. The two side support portions 230 are arranged at intervals from the central support portion 220 along the width direction of the platform 100. The upper surfaces of the central support portion 220 and the two side support portions 230 are joined to form a product support surface. The two side support portions 230 are inclined downward in a direction away from the central support portion 220. The upper end of the suction cup mounting plate 421 has a first contoured surface and two second contoured surfaces. The first contoured surface is parallel to the central support portion 220, and the two second contoured surfaces are parallel to the two side support portions 230 respectively.

[0032] Specifically, the suction cup 422 is configured as an accordion suction cup. The accordion suction cup has a retractable corrugated structure, which better adapts to the tilt angle of the side support portion 230 and the slight unevenness of the product 700 surface when in contact with the fixture 200, thereby increasing the actual adsorption area. When negative pressure is applied to the accordion suction cup, its corrugated portion undergoes elastic deformation, tightly adhering to the product support surface, further improving the sealing performance. This effectively avoids the problem of product 700 shifting or falling off due to unstable adsorption during the pressure holding process, ensuring the stability and reliability of the pressure holding operation.

[0033] like Figure 5As shown in this embodiment of the invention, the lifting drive mechanism 410 includes a lifting drive cylinder 411, a mounting top plate 413, and a guide rod 414. The mounting top plate 413 is mounted on the platform 100 and has a piston rod through hole and a guide rod through hole. The cylinder of the lifting drive cylinder 411 is connected to the lower surface of the mounting top plate 413. The piston rod of the lifting drive cylinder 411 passes through the piston rod through hole and drives the suction cup assembly 420. The guide rod 414 passes through the guide rod through hole and connects to the suction cup assembly 420. By setting the guide rod 414, the lifting movement of the suction cup assembly 420 can be guided, effectively preventing it from deviating or shaking during its up-and-down movement.

[0034] Specifically, the platform 100 also includes a bottom mounting bracket 130 and a middle mounting bracket 140 connecting the first base 110 and the second base 120. The bottom mounting bracket 130 and the middle mounting bracket 140 are spaced apart in a bottom-to-top direction. The lifting drive mechanism 410 also includes a mounting base plate 412. The mounting base plate 412 and the mounting top plate 413 are respectively disposed on the bottom mounting bracket 130 and the middle mounting bracket 140. The mounting base plate 412 is hollowed out. The top end of the cylinder is connected to the mounting top plate 413. The bottom end of the cylinder extends downward out of the mounting base plate 412 and is provided with a working interface. The lifting drive cylinder 411 is configured as an air valve. The working interface is used to connect to an air source.

[0035] Furthermore, a sleeve 415 is provided between the mounting top plate 413 and the mounting bottom plate 412. The sleeve 415 is aligned with the guide rod through hole, and a sliding bearing 416 is provided at the top of the sleeve 415. The guide rod 414 passes through the sliding bearing 416 and extends into the sleeve 415.

[0036] like Figures 1 to 6 As shown, the second aspect of this utility model provides a patching device, which includes the pressure holding device, jig 200, and conveying mechanism 600 described in the above embodiments.

[0037] The fixture 200 has a product bearing surface, and a through hole 210 is formed on the product bearing surface, which passes through the fixture 200. The fixture 200 is detachably mounted on the bearing position. The conveying mechanism 600 is used to convey the product 700 to the product bearing surface on the fixture.

[0038] This placement equipment enables automated placement of product 700, reducing labor costs and effectively improving the efficiency and consistency of placement operations. Specifically, the handling mechanism 600 is configured as a robotic arm, with a gripping or adsorption device at the end of the robotic arm corresponding to the product type 700.

[0039] In this embodiment of the utility model, the patch device also includes a transfer mechanism 300, which drives the pressure holding device to move between the loading station and the unloading station, thereby realizing automated transportation of the product 700, further improving the automation level of the production of the product 700, and improving the production efficiency of the product 700.

[0040] Specifically, the transfer mechanism 300 includes a linear guide module 310 and a drive motor 320. The linear guide module 310 extends from the loading station to the unloading station. The linear guide module 310 is provided with a slider 330 that connects to the platform 100. The drive motor 320 is located on the side of the linear guide module 310 near the loading station and drives the connecting slider 330.

[0041] Of course, this utility model is not limited to this. The transfer mechanism 300 can also be set as an AGV trolley or other forms of transportation device.

[0042] It should be noted that the product bearing surface of the jig 200 is provided with an adhesive layer, which is used to adhere the product 700 to the product bearing surface.
