Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production equipment, in particular to a protection device for a circuit board assembly production line. Background Art

[0002] During the PCBA assembly process, the circuit boards need to be placed on a conveyor belt for transportation. The circuit boards flow between different assembly processes, and the assembly of various electronic components is completed in different assembly processes. Two problems often arise during the production process of the circuit board assembly line. First, for large circuit boards, when the assembly workers put the circuit boards with some electronic components back on the conveyor belt, they may not place them properly, causing the circuit boards to exceed the conveyor belt range. The edges of the circuit boards may be scratched or even collide with the pillars on the production line, causing damage to the circuit boards and electronic components. Second, the circuit boards are transported on the conveyor belt without stopping. If the workers do not have time to pick up the circuit boards on the conveyor belt, the circuit boards will flow into the next process. This may cause the circuit boards to miss some electronic components, resulting in defective products that need to be reworked, affecting the production efficiency and quality of the circuit boards.

[0028] The specific implementation of the present utility model is introduced with reference to the accompanying drawings.

[0029] refer to Figure 1The figure is a schematic diagram of the three-dimensional structure of a circuit board assembly production line. The circuit board assembly production line is arranged in a straight line. The circuit board assembly production line is sequentially provided with a workbench 101, a storage table 102 and a lighting rack 103 from bottom to top. The conveyor belt 301 in the center of the workbench 101 is used to transport the circuit boards. The workbench 101 is sequentially provided with five assembly stations 201. A protection component 1 is provided between each assembly station 201 and the conveyor belt 301 to protect the circuit boards transported on the conveyor belt 301.

[0030] refer to Figures 1 to 5 , a protection device for a circuit board assembly production line, which is installed on a workbench 101 of the circuit board assembly production line, includes multiple protection components 1 installed along the direction of the conveyor belt 301, and the multiple protection components 1 are respectively arranged on multiple assembly stations 201 separated by multiple columns 104 of the workbench 101. The protection component 1 includes a baffle 2 and a partition. The two baffles 2 are respectively fixed to the table 202 of the assembly station 201 and are arranged parallel to the two side edges in the width direction of the conveyor belt 301. The baffle 2 is higher than the conveyor belt 301 and the table 202 of the assembly station 201 to form a guide groove that limits the circuit board to move only on the conveyor belt 301. The baffle 2 is provided with at least one card slot on the side close to the conveyor belt 301, and the partition is clamped in the two corresponding card slots of the two baffles 2. The partition placed horizontally above the conveyor belt 301 stops the circuit board on the conveyor belt 301 to carry out the loading operation between the conveyor belt 301 and the assembly station 201.

[0031] The protection device for a circuit board assembly production line in an embodiment of the present application protects the circuit board on the conveyor belt 301 by providing a group of protection components 1 at each assembly station 201. When the circuit board with some electronic components assembled on the assembly station 201 is placed back on the conveyor belt 301, the circuit board is limited by two baffles 2 so that it only falls within the range of the conveyor belt 301, avoiding collision between the circuit board and structures such as the columns 104 at the edge of the conveyor belt 301. The circuit board on the conveyor belt 301 is intercepted by the partition to avoid missing certain assembly processes, thereby improving the quality of the circuit board.

[0032] In order to protect the circuit board, in this embodiment, the baffle 2 is made of EVA material.

[0033] It can be understood that, in such a setting, EVA is ethylene-vinyl acetate copolymer, which is a general-purpose high molecular polymer. EVA is made into a baffle 2 by foaming, and then a slot is punched out on the baffle 2. The EVA foamed baffle 2 has the advantages of being light, elastic, flexible, and not easy to wrinkle. It can play a good buffering effect to protect the circuit board and prevent the circuit board from being scratched or colliding with the edge of the conveyor belt 301 and the column 104 of the assembly station 201.

[0034] In order to fix the baffle 2, in this embodiment, refer to Figure 1 The baffle 2 is fixed on the table 202 of the assembly station 201 by adhesive.

[0035] It can be understood that with such a setting, the EVA foam-molded baffle 2 is relatively light, and the baffle 2 can be quickly fixed on the table 202 by gluing, which is very convenient to install. At the same time, the baffle 2 can be easily cut and can be cut to a suitable length according to the range of the assembly station 201, which is convenient for processing.

[0036] In order to facilitate the assembly of the partition and the baffle 2, in this embodiment, reference Figure 1 and Figure 2 The baffle 2 has a slot along the thickness direction, and the bottom of the slot is located on the table 202 of the assembly station 201. Both ends of the partition are provided with plug connectors 31 that are locked in the slot. The plug connector 31 is locked in the slot and supported by the table 202 of the assembly station 201.

[0037] It can be understood that, with such a configuration, the two ends of the partition are engaged with the card slots of the baffle 2, so that the middle part of the partition is placed horizontally on the conveyor belt 301, and the middle part of the partition can be conveniently grasped to pick up and place the partition, which facilitates the assembly of the partition and the baffle 2. The plug connector 31 of the partition is in contact with the table 202, and the partition is lifted by the table 202 on both sides of the conveyor belt 301. The conveyor belt 301 is slightly lower than the table 202, so that the conveyor belt 301 does not contact the partition, so that the partition will not interfere with the operation of the conveyor belt 301, and will only stop the circuit board on the conveyor belt 301.

[0038] In order to realize different installation modes of the partition plate and the baffle plate 2, in this embodiment, reference is made to Figure 1 and Figure 2 The baffle 2 is divided into a first baffle 21 and a second baffle 22. The first baffle 21 and the second baffle 22 are both provided with three card slots in different directions, namely the first card slot 23, the second card slot 24 and the third card slot 25. The two ends of the partition are respectively clamped in the first card slot 23 of the first baffle 21 and the first card slot 23 of the second baffle 22, forming a first assembly mode between the partition and the baffle 2, and the two ends of the partition are respectively clamped in the second card slot 24 of the first baffle 21 and the third card slot 25 of the second baffle 22, forming a second assembly mode between the partition and the baffle 2, and the two ends of the partition are respectively clamped in the third card slot 25 of the first baffle 21 and the second card slot 24 of the second baffle 22, forming a third assembly mode between the partition and the baffle 2. The partition in the first assembly mode is vertically clamped between the first baffle 21 and the second baffle 22, the partition in the second assembly mode is inclined toward the first baffle 21, and the partition in the third assembly mode is inclined toward the second baffle 22.

[0039] It is understandable that, with such a configuration, the assembly stations 201 on both sides of the conveyor belt 301 can both assemble electronic components of the circuit board. However, since the arm lengths of the workers are different, both the second and third assembly methods can guide the circuit board to the edge of the conveyor belt 301, thereby facilitating the workers to pick up the circuit board stopped by the partition. The first assembly method has a greater advantage when assembling larger circuit boards. The partition perpendicular to the first baffle 21 and the second baffle 22 can stably stop the larger circuit board, preventing the circuit board from shaking too much during the stopping process. Among them, the order of the first card slot 23, the second card slot 24, and the third card slot 25 is not unique. As long as the three assembly methods of the partition and the baffle 2 can be realized, the first card slot 23 of this embodiment is located between the second card slot 24 and the third card slot 25. The second card slot 24 can also be arranged between the first card slot 23 and the third card slot 25, or the third card slot 25 can be arranged between the first card slot 23 and the second card slot 24.

[0040] In order to cooperate with the clamping of the partition, in this embodiment, reference Figure 1 and Figure 2 The second card slot 24 and the third card slot 25 are respectively located on both sides of the first card slot 23. The cross section of the first card slot 23 is a rectangle, and the cross sections of the second card slot 24 and the third card slot 25 are both parallelograms.

[0041] It can be understood that, with such a configuration, the first card slot 23 of the first baffle 21 faces the first card slot 23 of the second baffle 22, and the rectangular first card slot 23 can guide the partition to be inserted into the first card slot 23 of the other baffle 2, so that the partition is vertically clamped between the first baffle 21 and the second baffle 22; the second card slot 24 of the first baffle 21 faces the third card slot 25 of the second baffle 22, and the third card slot 25 of the first baffle 21 faces the second card slot 24 of the second baffle 22, and through the parallelogram second card slot 24 and the third card slot 25, the partition is guided to be obliquely clamped between the first baffle 21 and the second baffle 22.

[0042] In order to protect the circuit board, in this embodiment, reference Figure 2 and Figure 3 The partition includes a material-blocking partition 4, which includes a hollow frame 41 and a buffer layer 42. The buffer layers 42 are arranged on both sides of the frame 41 in the thickness direction. The frame 41 is made of plastic material. The two ends of the frame 41 are respectively clamped in the two corresponding slots of the two baffles 2.

[0043] It can be understood that, in such a configuration, the skeleton 41 is a hard plastic skeleton 41, such as PVC, HIPS, PET, PP, PE and acrylic material, so that the partition can have sufficient strength to ensure that it will not be broken by the circuit board, so that the partition can be stably placed horizontally on the conveyor belt 301. In the process of intercepting the circuit board, the circuit board is buffered by the buffer pad layer 42, which can well protect the circuit board. Buffer pad layers 42 are set on both sides of the skeleton 41, so that the partition can be installed on the baffle 2 regardless of direction, which facilitates the assembly of the partition.

[0044] In order to better protect the circuit board, in this embodiment, the buffer layer 42 is made of EVA material.

[0045] It is understandable that with such a setting, the cushion layer made of EVA foam has the advantages of being light, elastic, flexible, and not easy to wrinkle, and can play a good buffering effect to protect the circuit board.

[0046] In order to clean the conveyor belt 301 to prevent excessive impurities from adhering to the circuit board, in this embodiment, Figure 4 and Figure 5 The partition includes a dust collection partition 5 for an external blower. The dust collection partition 5 includes a main body 51, a buffer layer 42, a brush 52 and a scraper 53. The two ends of the main body 51 are respectively clamped in the two corresponding slots of the two baffles 2. The main body 51 is provided with a dust collection chamber 511. The dust collection port 512 of the dust collection chamber 511 is set toward the conveyor belt 301. The inner walls on both sides of the dust collection port 512 are respectively fixed with the brush 52 and the scraper 53. The buffer layer 42 is fixed to the outer wall of the main body 51 on one side of the brush 52. A connector 54 for an external blower is provided on the main body 51, and the connector 54 is communicated with the dust collection chamber 511.

[0047] The dust collecting baffle 511 is connected to the dust collecting port 512 by the dust collecting baffle 52, and the dust collecting baffle 53 is connected to the dust collecting chamber 511 and the dust collecting port 512. The brush 52 and the scraper 53 are in contact with the running conveyor belt 301. The brush 52 brushes the conveyor belt 301 to lift up the dust and particulate impurities on the conveyor belt 301, which then enter the dust collecting port 512 and are sucked out. The scraper 53 scrapes the conveyor belt 301, intercepts the heavier particles on the conveyor belt 301, and is sucked out by the negative pressure of the dust collecting chamber 511, thereby cleaning up the dust and particles on the conveyor belt 301, ensuring the cleanliness of the conveyor belt 301, avoiding the circuit board from rubbing against the impurities on the conveyor belt 301, thereby protecting the circuit board, and avoiding excessive impurities adhering to the circuit board, thereby improving the quality of the circuit board.

[0048] In order to better clean the conveyor belt 301 , in this embodiment, the scraper 53 is a flexible scraper 53 made of plastic.

[0049] It is understandable that, with such a configuration, the flexible scraper 53 made of plastic material can have a good fit with the conveyor belt 301 , ensuring that the scraper 53 can stably scrape the conveyor belt 301 while preventing the scraper 53 from scratching the conveyor belt 301 .

[0050] The embodiment of the present application protects the circuit board on the conveyor belt 301 by providing a group of protection components 1 at each assembly station 201. When the circuit board with some electronic components assembled on the assembly station 201 is placed back on the conveyor belt 301, the circuit board is limited by two baffles 2 so that the circuit board only falls within the range of the conveyor belt 301, thereby avoiding collision between the circuit board and structures such as the columns 104 at the edge of the conveyor belt 301; the partition can be installed in real time according to the assembly station 201, and the installation is flexible. When the circuit board is transported through the assembly station 201 by the conveyor belt 301 and is not picked up by the workers in time, it will be stopped by the partition, thereby avoiding the circuit board from missing certain assembly processes and improving the quality of the circuit board; in the process of stopping the circuit board, the partition is buffered by the buffer pad to protect the circuit board.

[0051] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
