Abstract
Description
Technical Field
[0001] The utility model relates to an automatic pressing device for a PCB board, belonging to the technical field of mechanical automation. Background Art
[0002] The PCB printed circuit board is a commonly used electronic component, which is a support for electronic components and also a carrier for the electrical connection of electronic components. Since it is made by electronic printing technology, it can also be called a printed circuit board. The PCB board can connect various electronic components through circuits, playing a role of conduction and transmission, and is a key electronic interconnection component in electronic products. In particular, each electronic device cannot do without a PCB board, so the manufacturing quality of the PCB board directly affects the stability and service life of electronic products.
[0003] Currently, the PCB board and electronic products are often installed by the way of pressing down with a quick clamp. The quick clamp can accurately position and quickly clamp the product, and is widely used as a fixture in the process of product welding, riveting, assembly and other processes. However, the stroke of the quick clamp is not stable enough. When pressing the PCB board, it is easy to cause the phenomenon of gaps or incomplete pressing in the pressing. In addition, the operator manually operates the quick clamp, which will be relatively laborious after long-term use. And the operator manually controls the quick clamp, and its force cannot be accurately controlled, which will cause damage to the PCB board during pressing, thus affecting the yield of the product. Therefore, there is an urgent need for an automatic pressing device for a PCB board to solve the stable pressing between the PCB board and electronic products. Summary of the Utility Model
[0004] The content part of this application is used to introduce concepts in a brief form, and these concepts will be described in detail in the following detailed implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.
[0005] Aiming at the problems and deficiencies existing in the prior art, the purpose of the utility model is to provide an automatic pressing device for a PCB board. The utility model mainly replaces the quick clamp with a pressing cylinder above the fixed mounting plate. By controlling the rising and falling of the pressing cylinder, the stroke can be stabilized to achieve a suitable pressing position, and it can ensure that the PCB board is not damaged during pressing. To solve the problems raised in the above background art.
[0006] To achieve the above object, the present utility model provides the following technical solutions: It includes a fixed mounting plate, above which a pressing cylinder is connected and arranged. The output shaft of the pressing cylinder is connected to one end of a transfer plate, and the other end of the transfer plate is connected to a PCB pressing column. Above the fixed mounting plate, there is also a product carrier. The product is loaded into the product carrier, and the position of the PCB pressing column is corresponding to that of the product.
[0007] Preferably, a product positioning block is passed through corresponding positioning holes formed in the product carrier and the fixed mounting plate for connection. By forming positioning holes in the product carrier and the fixed mounting plate and passing the product positioning block through these two positioning holes for connection, the movable fixation of the product carrier can be further achieved.
[0008] Preferably, the number of positioning holes formed in the product carrier and the fixed mounting plate is at least two each. Specifically, at least two positioning holes are formed at the side edge of the product carrier, and at least two positioning holes are also formed in the fixed mounting plate. During use, according to the size and loading position of the product, the positioning holes close to the product position can be selected, and the product positioning block is passed through the positioning holes for connection. Thus, the positions of the product carrier and the product on the fixed mounting plate can be adjusted to make the product accurately correspond to the position directly below the PCB pressing column.
[0009] Preferably, an auxiliary pressing head is connected to the lower end of the PCB pressing column. The diameter of the auxiliary pressing head is larger than that of the PCB pressing column, and the diameter of the auxiliary pressing head is smaller than the inner diameter of the product opening. Since the diameter of the auxiliary pressing head at the lower end of the PCB pressing column is larger than that of the PCB pressing column, the force application area of the auxiliary pressing head is larger than that of the PCB pressing column. At the same time, since the diameter of the auxiliary pressing head is slightly smaller than the inner diameter of the product opening, the auxiliary pressing head can smoothly move down into the product. This can increase the force application area when the product is press-fitted with the PCB board to ensure the integrity during the PCB board press-fitting.
[0010] Compared with the prior art, the beneficial effects of the present utility model are:
[0011] The utility model has the characteristics of simple structure and convenient operation, and the pressing efficiency and product yield can also be effectively improved. The utility model mainly completes the pressing operation of the PCB board through the downward pressing cylinder fixedly installed. The output shaft of the downward pressing cylinder is connected to the PCB pressing column through an adapter plate. The product to be pressed is loaded into the product carrier above the fixedly installed plate and corresponds to the PCB pressing column. In addition, the position of the product carrier can be adjusted by combining the product positioning block with a plurality of positioning holes opened on the product carrier and the fixedly installed plate, so as to realize the adjustment setting according to the specific position after the product is loaded. Furthermore, the diameter of the auxiliary pressing head connected to the lower end of the PCB pressing column is larger than that of the PCB pressing column, increasing the force application area of the auxiliary pressing head, thereby expanding the force application area when the product is pressed against the PCB board, ensuring the integrity and stability when the PCB board is pressed, and effectively improving the yield rate of the product after pressing.

[0018] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.
[0019] An automatic PCB board pressing device provided in this embodiment is as Figure 1As shown in the figure: it includes a fixed mounting plate 1, a downward pressing cylinder 2 is connected above the fixed mounting plate 1, and the output shaft of the downward pressing cylinder 2 is connected to one end of a transfer plate 6, and the other end of the transfer plate 6 is connected to a PCB pressing post 5. Above the fixed mounting plate 1, there is also a product carrier 3. The product 4 is loaded into the product carrier 3, and the positions of the PCB pressing post 5 and the product 4 are corresponding. The product carrier 3 is arranged above the fixed mounting plate 1 and on the side of the downward pressing cylinder 2. When in use, the product 4 to be press-fitted is placed in the product carrier 3, so that the PCB board and the product 4 are not prone to sliding during the press-fitting process.
[0020] This embodiment further includes that a product positioning block 7 is connected through corresponding positioning holes opened on the product carrier 3 and the fixed mounting plate 1, and the number of positioning holes opened on the product carrier 3 and the fixed mounting plate 1 is set to be multiple. By passing the product positioning block 7 through the corresponding positioning holes opened on the product carrier 3 and the fixed mounting plate 1, the movable fixation of the product carrier can be further realized. A plurality of positioning holes are opened on both the product carrier 3 and the fixed mounting plate 1. During use, according to the size and loading position of the product 4, the positioning holes close to the position of the product 4 can be selected, and the product positioning block 7 is passed through the positioning holes for connection. Thus, the positions of the product carrier 3 and the product 4 on the fixed mounting plate 1 can be adjusted, so that the product 4 is accurately corresponding to the directly below of the PCB pressing post 5.
[0021] This embodiment further includes that an auxiliary pressing head 8 is connected to the lower end of the PCB pressing post 5. The diameter of the auxiliary pressing head 8 is larger than that of the PCB pressing post 5, and the diameter of the auxiliary pressing head 8 is smaller than the inner diameter of the opening of the product 4. The diameter of the auxiliary pressing head 8 at the lower end of the PCB pressing post 5 is larger than that of the PCB pressing post 5, which can increase the force application area of the auxiliary pressing head 8. In addition, the diameter of the auxiliary pressing head 8 is slightly smaller than the inner diameter of the opening of the product 4, so that the auxiliary pressing head 8 can smoothly move down into the interior of the product 4. Through such a setting, the force application area when the product 4 and the PCB board are press-fitted can be enlarged, so as to ensure the integrity and stability during the press-fitting of the PCB board.
[0022] The usage method of the present utility model
[0023] Preparatory work before use: First, load the product 4 into the product carrier 3. According to the position of the product 4 after loading, adjust the position of the product carrier 3 on the fixed mounting plate 1 so that the product 4 corresponds to the directly below of the PCB pressing post 5. It is also necessary to adjust the downward pressing height after the downward pressing cylinder 2 is started, to prevent the downward pressing cylinder 2 from driving the PCB pressing post 5 to press down insufficiently due to too high a height, and also to avoid damaging the PCB board due to too low a height when the downward pressing cylinder 2 drives the PCB pressing post 5 to press down. At the same time, in combination with adjusting the downward pressing force of the downward pressing cylinder 2 through a pressure gauge, determine the pressure that the PCB board can withstand.
[0024] During use, the operator places the product 4 in the product carrier 3. After confirming the direction, the PCB board is placed inside the product 4. The pressing cylinder 2 is started, and the pressing down and rising of the cylinder are controlled by the solenoid valve on the pressing cylinder 2. That is, the operator ensures the direction of the product 4 while the PCB board is placed in place. Then, the start switch of the pressing cylinder 2 is pressed, and the pressing cylinder 2 performs the pressing down action to complete pressing the PCB board into the product 4. After the press-fitting is completed, the pressing cylinder 2 is controlled again to make the pressing cylinder 2 perform the rising action. At this time, the operator can take out the product 4 that has completed the press-fitting from the product carrier 3 and place it in the designated area, thus completing a press-fitting operation of the PCB board. Subsequently, the operator continues the press-fitting operation of the next product.
[0025] In the description of the present utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0026] In addition to the above embodiments, the present utility model can also have other embodiments. For those skilled in the art, it is still possible to modify the technical solutions recorded in the above embodiments, or perform equivalent replacements for some of the technical features.
