Description

Technical Field

[0001] This application relates to the field of pressing tooling, and more particularly to a pneumatic pressing tooling. Background Technology

[0002] In the manufacturing process of electronic products such as circuit boards, lamination is one of the key steps to ensure that the components are tightly joined and achieve the expected functions. Currently, lamination methods in some scenarios mainly include the following two types: manual direct lamination and manual lamination fixture-assisted lamination. Manual direct lamination is labor-intensive, inefficient, and cannot guarantee lamination quality and reliability. While manual lamination fixture-assisted lamination reduces labor intensity, it still faces the problem of low efficiency and, since it still uses manual lamination, the stability in terms of lamination quality and reliability is also poor.

[0003] Therefore, this application studies a pneumatic pressing tool that improves efficiency while ensuring pressing quality and reliability. Utility Model Content

[0004] In order to improve efficiency while ensuring pressing quality and reliability, this application provides a pneumatic pressing fixture.

[0005] This application provides a pneumatic pressing tooling, which adopts the following technical solution:

[0006] A pneumatic pressing fixture includes a machine base, a drive component, a pressure plate, a guide rod, a limiting block, a contouring upper mold, and a contouring lower mold. The drive component is connected to the upper end of the machine base, and its output end passes through the machine base and is slidably disposed. The output end of the drive component is connected to the pressure plate. The guide rod is connected between the pressure plate and the machine base. The machine base has a fixture platform. The limiting block is disposed on the fixture platform. The contouring upper mold is installed on the side of the pressure plate facing the fixture platform. The contouring lower mold is installed on the side of the fixture platform facing the pressure plate, and the contouring upper mold and the contouring lower mold are disposed correspondingly.

[0007] By adopting the above technical solution, during the pressing process, the driving component provides a stable driving force to push the pressure plate downwards. Guided by the guide rod, the pressure plate moves along a predetermined trajectory. Simultaneously, the upper and lower contouring molds gradually approach and contact the circuit board. When the pressure plate reaches the position of the limit block, the pressing process ends. The limit block prevents excessive pressure on the circuit board in case of incorrect stroke. At this point, the upper and lower contouring molds apply uniform pressure to the circuit board, ensuring a tight fit between its components. This ensures that while improving efficiency, the pressing quality and reliability are guaranteed.

[0008] Optionally, the limiting block includes a fixing part, a connecting part and a limiting part connected in sequence. The length of the limiting part and the fixing part is longer than that of the connecting part. The limiting part is connected to the tooling platform and the fixing part faces the pressure plate.

[0009] By adopting the above technical solution, due to the long length of the limiting part, it can provide sufficient contact area and support force, thereby effectively limiting the downward distance of the pressure plate. When the pressure plate reaches the limiting part, it will be blocked by the limiting block and stop moving. At this time, the circuit board has been pressed together evenly.

[0010] Yes, a reinforcing part is connected to one side between the fixing part and the connecting part.

[0011] Optionally, the machine tool is also equipped with bearings, which are fitted onto the guide rod.

[0012] Optionally, a floating joint connects the drive unit to the pressure plate.

[0013] By adopting the above technical solution, the floating joint can absorb the error caused by the possible eccentricity or offset angle between the cylinder and the pressure plate, allowing a certain degree of freedom so that the pressure plate can better fit the product surface and ensure the accuracy and stability of the pressing operation.

[0014] Optionally, a pressure holding delay relay is also included, which is mounted on the machine base.

[0015] By adopting the above technical solution, the pressure of the cylinder is controlled to be maintained for a certain period of time after the pressing is completed, so as to ensure the pressing effect.

[0016] Optionally, an emergency stop button is provided on one side of the tooling platform, and start buttons are provided on both sides of the emergency stop button. The two start buttons are activated simultaneously to start the movement of the driving components.

[0017] By adopting the above technical solution, in the event of an emergency, pressing this button can immediately stop the cylinder's operation to prevent accidents; both start buttons must be pressed simultaneously to activate the drive mechanism, ensuring operational safety.

[0018] Optionally, folding handles are provided on both sides of the tooling platform.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. During the pressing process, the driving component provides a stable driving force to push the pressure plate downwards. Guided by the guide rod, the pressure plate moves along a predetermined trajectory. Simultaneously, the upper and lower contouring molds gradually approach and contact the circuit board. When the pressure plate reaches the position of the limit block, the pressing process ends. The limit block prevents excessive pressure on the circuit board in case of incorrect stroke. At this point, the upper and lower contouring molds apply uniform pressure to the circuit board, ensuring a tight fit between its components. This ensures that while improving efficiency, the pressing quality and reliability are guaranteed.

[0021] 2. Due to the relatively long length of the limiting part, it can provide sufficient contact area and support force, thereby effectively limiting the downward distance of the pressure plate. When the pressure plate reaches the limiting part, it will be blocked by the limiting block and stop moving. At this time, the circuit board has been evenly pressed together.

[0022] 3. In case of emergency, pressing this button will immediately stop the cylinder's operation to prevent accidents; both start buttons must be pressed simultaneously to activate the drive mechanism and ensure operational safety. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses a pneumatic pressing tool. (Refer to...) Figure 1 and Figure 2 The pneumatic pressing fixture includes a machine base 1, a drive unit 6, a pressure plate, a guide rod 2, a limiting block 3, a contouring upper mold 4, and a contouring lower mold 5. In this embodiment, the drive unit 6 is an adjustable cylinder. The drive unit 6 is connected to the upper end of the machine base 1, and its output end passes through the machine base 1 and is slidably disposed. The output end of the drive unit 6 is connected to the pressure plate. The drive unit 6 drives the pressure plate to move up and down. The stroke of the cylinder can be controlled by an external device to control the movement stroke of the pressure plate. In some embodiments, a floating joint 8 is connected between the drive unit 6 and the pressure plate. One side of the floating joint 8 is screwed to the pressure plate. The floating joint 8 can absorb the error caused by the possible eccentricity or offset angle between the cylinder and the pressure plate, allowing a certain degree of freedom so that the pressure plate can better fit the product surface and ensure the accuracy and stability of the pressing operation.

[0028] Guide rod 2 connects the pressure plate and machine base 1. In some embodiments, a bearing is also provided inside the machine base 1, and the bearing is sleeved on the guide rod 2. The machine base 1 has a tooling platform 7, a limiting block 3 is provided on the tooling platform 7, an upper contouring die 4 is installed on the side of the pressure plate facing the tooling platform 7, and a lower contouring die 5 is installed on the side of the tooling platform 7 facing the pressure plate, with the upper contouring die 4 and the lower contouring die 5 correspondingly arranged. This allows the pressure plate to move precisely through the driving component 6, forming a precise pressing of the circuit board by the upper contouring die 4 and the lower contouring die 5, thereby ensuring the pressing quality of the circuit board. At the same time, the limiting block 3 prevents the circuit board from being over-pressed due to incorrect stroke setting of the driving component 6, which could lead to damage to the circuit board, further ensuring the pressing quality and reliability of the circuit board. Moreover, the pressing tooling can improve the pressing efficiency.

[0029] Reference Figure 2 In some embodiments, the limiting block 3 includes a fixing part 31, a connecting part 32, and a limiting part 33 integrally connected in sequence. The lengths of the limiting part 33 and the fixing part 31 are both longer than the connecting part 32. The limiting part 33 is connected to the tooling platform 7, and the fixing part 31 faces the pressure plate. In this embodiment, the limiting part 33 has connecting holes on both sides of the connecting part 32, and is fixed to the tooling platform 7 by screwing through the connecting holes. Because the limiting part 33 is relatively long, it can provide sufficient contact area and supporting force, thereby effectively limiting the downward distance of the pressure plate.

[0030] Reference Figure 2 In some embodiments, a reinforcing portion 34 is integrally connected to one side between the fixing portion 31 and the connecting portion 32. The reinforcing portion 34 enhances the overall strength of the limiting block 3 by providing additional support and rigidity, which helps ensure that the limiting block 3 maintains its shape and size during the pressing process, thereby providing a stable limiting effect. The design of the reinforcing portion 34 helps reduce the vibration and sway of the limiting block 3 under force, improving its stability. By enhancing the strength and stability of the limiting block 3, the reinforcing portion 34 helps extend its service life and reduce wear and damage caused by long-term force.

[0031] Refer again Figure 1 In some embodiments, the pneumatic pressing fixture also includes a pressure-holding delay relay 9, which is mounted on the machine base 1. The control cylinder maintains pressure for a certain period after pressing is completed to ensure the pressing effect.

[0032] In some embodiments, an emergency stop button 10 is provided on one side of the tooling platform 7, and start buttons 11 are provided on both sides of the emergency stop button 10. The two start buttons 11 are activated simultaneously to move the driving component 6. The two start buttons 11 must be pressed at the same time to activate the driving component 6, which provides a double guarantee and ensures operational safety.

[0033] In some embodiments, folding handles 12 are provided on both sides of the tooling platform 7. The tooling can be easily moved by using the folding handles 12.

[0034] The implementation principle of a pneumatic pressing fixture according to an embodiment of this application is as follows: During the pressing process, the driving component 6 provides a stable driving force to push the pressure plate downward. The pressure plate moves along a predetermined trajectory guided by the guide rod 2. At the same time, the upper and lower contouring molds 4 and 5 gradually approach and contact the circuit board. When the pressure plate reaches the position of the limiting block 3, the pressing process ends. The limiting block 3 prevents excessive compression of the circuit board when the stroke is incorrect. At this time, the upper and lower contouring molds 4 and 5 apply uniform pressure to the circuit board, ensuring that its components are tightly joined, thereby ensuring pressing quality and reliability while improving efficiency.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
