Description

Technical Field

[0001] This utility model relates to the field of trolley technology for circuit board production, and in particular to a circuit board assembly trolley for circuit board production. Background Technology

[0002] In the electronics manufacturing industry, circuit boards are a core component, and the degree of automation in their production process directly affects product quality and production efficiency. Traditional circuit board production assembly equipment mainly adopts a combination structure of fixed assembly tables and single-layer storage racks, typically consisting of fixed supports, a horizontal assembly platform, and a single storage layer.

[0003] Regarding the aforementioned technologies, it has been found that the height of the board receiving platform in traditional circuit board production equipment is fixed, which cannot adapt to changes in the output height of different production lines or different specifications of circuit boards on the same production line. At the same time, the method of fixing it directly at the end of the production line cannot achieve the movement and adjustment of the equipment. When it is necessary to temporarily adjust the production task, since the board receiving equipment cannot be moved, it is necessary to allocate forklifts to transport the circuit boards, which increases logistics costs and transfer time.

[0004] Furthermore, most traditional circuit board production and assembly equipment adopts a single-layer storage rack structure without layered isolation design. When circuit boards are stacked, the lower layer board is easily deformed by the pressure of the upper layer board. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a circuit board production board assembly trolley.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A circuit board manufacturing assembly trolley includes a movable base, a multi-layer frame vertically mounted on the upper surface of the movable base, the multi-layer frame being fixedly connected to the movable base, a guide seat mounted at the front end of the multi-layer frame, a movable frame slidably mounted on the guide seat, and a drive component for driving the movable frame to rise and fall on the guide seat. An assembly shell is mounted on the movable frame, one end of the assembly shell being rotatably connected to the movable frame, and an electric cylinder for driving the assembly shell to flip is also provided on the movable frame.

[0008] As a preferred embodiment, the movable seat includes a device plate and movable wheels, the movable wheels being evenly installed on the lower end surface of the device plate and fixedly connected to the device plate.

[0010] As a preferred embodiment, the guide seat includes a seat plate and a guide frame for sliding installation of the movable frame. The guide frame is installed on the upper end surface of the seat plate and is fixedly connected to the seat plate.

[0011] As a preferred embodiment, the movable frame includes a middle plate and a housing, the housing being fixedly installed at both ends of the middle plate and slidably installed on the guide frame.

[0012] As a preferred embodiment, the driving component includes a motor and a driving screw. The motor is fixedly mounted on the upper end face of the base plate, the driving screw is connected to the output end of the motor, and a threaded sleeve that mates with the driving screw is fixedly mounted on the outer surface of the housing.

[0013] As a preferred embodiment, the connecting plate shell includes a bottom plate shell and side plates, the side plates are installed on both sides of the bottom plate shell, and the side plates are integrally formed with the bottom plate shell.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application realizes the lifting and lowering of the movable frame and the flipping of the receiving shell driven by the electric cylinder through a driving component, which can quickly and accurately receive circuit boards with different heights and place them on the placement tray of the multi-layer frame, greatly improving the board receiving efficiency. The design of the movable seat allows the receiving trolley to move freely in the production workshop, which is convenient for deployment between different production lines and improves the utilization rate of the equipment. At the same time, the baffles of the multi-layer frame and the side plates of the receiving shell can effectively prevent the circuit boards from being bumped and scratched during storage and receiving, protecting the quality of the circuit boards. Moreover, the lifting function of the movable frame and the multi-layer design of the multi-layer frame can adapt to the production needs of circuit boards of different specifications and heights, and have strong versatility and adaptability.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3As shown, a circuit board production receiving trolley includes a movable base 1. A multi-layer frame 2 is vertically mounted on the upper surface of the movable base 1 and is fixedly connected to the movable base 1. A guide seat 3 is mounted at the front end of the multi-layer frame 2, and a movable frame 4 is slidably mounted on the guide seat 3. A drive component 5 for driving the movable frame 4 to rise and fall is mounted on the guide seat 3. A receiving shell 6 is mounted on the movable frame 4, with one end of the receiving shell 6 rotatably connected to the movable frame 4. An electric cylinder 7 for driving the receiving shell 6 to tilt is also provided on the movable frame 4. By setting the movable base 1, the receiving trolley can be flexibly moved to a suitable position on the circuit board production line for convenient circuit board reception. It can be moved to the end of the conveyor belt used for circuit board production to receive circuit boards. The design of the multi-layer frame 2 increases the storage capacity of the receiving trolley and enables the layered placement of circuit boards. The cooperation between the guide seat 3 and the movable frame 4 allows the movable frame 4 to rise and fall stably on the guide seat 3, thereby adjusting the height of the receiving shell 6 to accommodate circuit boards of different heights for unloading. The drive unit 5 provides power for the lifting and lowering of the movable frame 4, ensuring the automation and precision of the height adjustment of the receiving plate housing 6. The receiving plate housing 6 is rotatably connected to the movable frame 4 and is driven to flip by the electric cylinder 7, facilitating the accurate placement of received circuit boards onto the placement tray 22 of the multi-layer frame 2, thus improving the efficiency of receiving and storing boards. The electric cylinder 7 can be an electric push rod type, such as the DT series electric push rod, which has advantages such as large thrust and adjustable stroke, and can meet the needs of flipping the receiving plate housing 6.

[0028] Reference Figure 1 As shown, the movable base 1 includes a device plate 11 and movable wheels 12. The movable wheels 12 are evenly installed on the lower end face of the device plate 11 and are fixedly connected to the device plate 11. The movable base 1 consists of the device plate 11 and the movable wheels 12. The device plate 11 provides a stable mounting base for components such as the multi-layer frame 2, ensuring the structural stability of the entire pallet-receiving trolley. The movable wheels 12 are evenly installed on the lower end face of the device plate 11, allowing the pallet-receiving trolley to move flexibly, facilitating transfer between different production areas and improving the flexibility and adaptability of the equipment. The device plate 11 can be made of high-strength steel plate, such as Q235 steel plate, and the thickness can be selected according to the actual load-bearing requirements to ensure that it has sufficient strength and stability to support the weight of the entire pallet-receiving trolley. The movable wheels 12 can be swivel casters, such as polyurethane swivel casters, which have advantages such as wear resistance and quiet operation. The swivel casters should be equipped with a braking device to facilitate fixing the position of the pallet-receiving trolley during pallet receiving.

[0029] Reference Figure 1As shown, the multi-layer frame 2 includes a baffle 21 and a horizontally arranged storage tray 22. The storage tray 22 is evenly installed on one side of the baffle 21 from top to bottom, and the storage tray 22 is fixedly connected to the baffle 21. The baffle 21 of the multi-layer frame 2 prevents the stored circuit boards from slipping off the storage tray 22, thus protecting the circuit boards. The horizontally arranged storage tray 22, evenly installed on one side of the baffle 21 from top to bottom, provides multiple independent storage spaces for the circuit boards, facilitating the classification and storage of circuit boards of different specifications or batches, and also making it convenient for staff to retrieve and place the circuit boards. The baffle 21 can be made of aluminum alloy sheet, which is lightweight and corrosion-resistant. The storage tray 22 can be made of plastic, such as polypropylene (PP) plastic, which has a smooth surface, is not easy to scratch the circuit boards, and has a certain degree of elasticity, which can play a cushioning and protective role.

[0030] Reference Figure 2 and Figure 4 As shown, the guide seat 3 includes a seat plate 31 and a guide frame 32 for sliding installation of the movable frame 4. The guide frame 32 is installed on the upper surface of the seat plate 31 and is fixedly connected to the seat plate 31. The seat plate 31 of the guide seat 3 provides installation support for the guide frame 32, ensuring the stability of the guide frame 32. The guide frame 32 provides precise guidance for the sliding of the movable frame 4, making the movable frame 4 more stable during lifting and lowering, avoiding swaying and deviation, thereby ensuring the accuracy of the height adjustment of the connecting plate shell 6. The seat plate 31 can be made of the same Q235 steel plate as the equipment plate 11, and the guide frame 32 can be made of channel steel or I-beams to ensure that it has sufficient strength and rigidity to support the sliding of the movable frame 4. The surface of the guide frame 32 should be ground to reduce the friction when the movable frame 4 slides.

[0031] Reference Figure 3 and Figure 4 As shown, the movable frame 4 includes a middle plate 41 and a housing 42. The housing 42 is fixedly installed at both ends of the middle plate 41 and slidably installed on the guide frame 32. The middle plate 41 of the movable frame 4 is used to install components such as the connecting plate housing 6, allowing the connecting plate housing 6 to be flipped and used on the middle plate 41. The housing 42 is fixedly installed at both ends of the middle plate 41 and slidably installed on the guide frame 32. This structural design makes the sliding of the movable frame 4 on the guide frame 32 smoother, and also enhances the overall structural strength of the movable frame 4, ensuring the stability of the connecting plate housing 6 during the lifting process. The middle plate 41 can be made of aluminum alloy to reduce the weight of the movable frame 4 and reduce the load on the drive component 5. The housing 42 can be made of copper alloy, which has good wear resistance and self-lubricating properties, ensuring its smooth sliding on the guide frame 32.

[0032] Reference Figure 2 and Figure 3As shown, the driving component 5 includes a motor 51 and a drive screw 52. The motor 51 is fixedly mounted on the upper surface of the base plate 31, and the drive screw 52 is connected to the output end of the motor 51. A threaded sleeve 421 that mates with the drive screw 52 is fixedly mounted on the outer surface of the housing 42. The driving component 5 uses a combination of the motor 51 and the drive screw 52. The motor 51 serves as the power source, converting rotational motion into linear motion through the drive screw 52, ​​driving the movable frame 4 to rise and fall. The threaded sleeve 421 mates with the drive screw 52, ​​ensuring that the power of the motor 51 is accurately transmitted to the movable frame 4, achieving precise lifting and lowering control of the movable frame 4. This driving method has the advantages of high transmission efficiency and high control precision, and can meet the needs of connecting plates of different heights. The motor 51 can be a stepper motor, such as the 57 series stepper motor 51, which has advantages such as high control precision and large torque. The motor 51 should be equipped with a suitable driver, such as a DM542 driver, to achieve precise speed and position control. The drive screw 52 can be a ball screw, which features high transmission efficiency and high precision. The diameter and pitch of the screw can be selected according to the load and lifting speed requirements of the movable frame 4.

[0033] Reference Figure 5 As shown, the connector housing 6 includes a base housing 61 and side plates 62. The side plates 62 are installed on both sides of the base housing 61 and are integrally formed with the base housing 61. The base housing 61 of the connector housing 6 is used to support the circuit board. The integrally formed side plates 62 are installed on both sides of the base housing 61, which not only enhances the overall structural strength of the connector housing 6, but also prevents the circuit board from slipping off the sides, effectively protecting the circuit board during the connector process. The base housing 61 and side plates 62 can be made of ABS plastic in one piece, which has good toughness and strength and can effectively protect the circuit board.

[0034] In this embodiment, during actual use, the board receiving trolley is first moved to a suitable position on the circuit board production line, and the moving wheels are fixed by a braking device. Based on the output height of the circuit board, motor 51 is started, driving the drive screw 52 to rotate, which in turn drives the movable frame 4 to rise and fall, bringing the board receiving shell 6 to the appropriate receiving height. After the circuit board enters the receiving shell 6, the height of the receiving shell 6 is changed by the drive component 5. After moving to a position adapted to the corresponding height of the placement tray 22, the electric cylinder 7 is started, driving the receiving shell 6 to flip, placing the circuit board onto the placement tray 22 of the multi-layer frame 2. This process is repeated until the placement tray is full of circuit boards, and then the board receiving trolley is moved to the designated storage area.

[0035] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
