Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production equipment, and particularly discloses an automatic loading and unloading device. Background Art

[0002] PCB boards are usually transported in a board storage box. In the prior art, the traditional unloading method for PCB boards placed in the board storage box is to unload them manually. The manual method not only has low production efficiency, but also easily damages the PCB boards during the transfer process, thus affecting the processing quality. Summary of the Utility Model

[0003] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the utility model is to provide one.

[0004] To achieve the above purpose, an automatic loading and unloading device of the utility model comprises a base, a vertical and horizontal module arranged on the base, and a pushing mechanism. The vertical and horizontal module includes a vertical and horizontal moving screw rod group, a first driving motor, and a moving table sleeved on the vertical and horizontal moving screw rod group through a nut. An external board storage box for storing external board pieces is placed on the moving table. The moving table is in lifting and matching connection with the base. The first driving motor drives the vertical and horizontal moving screw rod group to drive the external board storage box on the moving table to move up and down. The pushing mechanism is fixedly arranged on the base and is used to push out the external board pieces in the board storage box for loading.

[0005] The external board storage box is placed on the moving table and fixed. The first driving motor is started to drive the vertical and horizontal module to work, so that the moving table and the external board storage box rise to a designated position. The pushing mechanism is controlled according to signals or programs to sequentially push the board pieces in the external board storage box to the next process. After a box of board pieces is pushed, another external board storage box full of board pieces is replaced in front of the pushing mechanism to continue pushing the board pieces. The whole process is carried out in a cycle until all board pieces are processed. The automated operation means that the machine can continuously and quickly complete the loading and unloading process of the board pieces with little or no human intervention, thus significantly improving the overall efficiency of the production line.

[0006] The mobile station includes a support plate and multiple groups of limit plates arranged on the support plate. A clamping plate is provided on the side away from the limit plates. The limit plates and the clamping plate are used to clamp an external storage box. The clamping plate can be a spring piece. The elastic buffering effect of the spring piece can reduce the vibration and impact generated during the movement of the storage box, protect the plate components from damage, and reduce the noise generated by the equipment due to vibration. Through the combined action of the limit plates and the clamping plate, the external storage box can be firmly clamped on the mobile station. This stable clamping method not only ensures that the storage box does not shake or fall off during movement, but also improves the stability and safety of the entire loading and unloading process. The design of multiple groups of limit plates allows the mobile station to adapt to external storage boxes of different sizes and shapes. By adjusting the position or quantity of the limit plates, various specifications of storage boxes can be flexibly clamped, thereby improving the versatility and adaptability of the equipment. By automatically clamping and releasing the external storage box, the operator can replace the storage box more conveniently without manually fixing or adjusting the position of the storage box. This not only simplifies the operation process, but also reduces manual intervention and potential operation errors.

[0007] The automatic loading and unloading equipment further includes a blanking mechanism. The blanking mechanism includes a transfer rail component arranged on the base and a blanking loading and unloading mechanism slidably arranged on the transfer rail component. The blanking loading and unloading mechanism can be designed according to the shape, size and weight of the plate components to ensure that the plate components are not damaged or dropped during transportation. At the same time, the loading and unloading mechanism can also be quickly replaced and adjusted to adapt to different types of plate components. Through the cooperation of the transfer rail component and the blanking loading and unloading mechanism, the equipment can automatically complete the blanking process of the plate components without manual intervention. This not only reduces the labor intensity, but also reduces the possibility of human errors.

[0008] The transfer rail component includes a transfer guide rail, a transfer lead screw and a second driving motor for driving the transfer lead screw to rotate. There are two groups of transfer guide rails, and the two groups of transfer guide rails are arranged in parallel. The blanking loading and unloading mechanism moves up and down through being slidably arranged on the two groups of transfer guide rails and moving along the direction of the two groups of transfer guide rails. The double-guide rail design disperses the pressure and friction during the movement of the blanking loading and unloading mechanism, reducing the wear degree of the guide rails and the loading and unloading mechanism. This helps to extend the service life of the equipment and reduce the maintenance cost. The transfer lead screw realizes the precise movement of the blanking loading and unloading mechanism through the drive of the second driving motor. The lead screw drive has the characteristics of high precision, high stability and high load capacity, and can meet the requirements for precise position control in automated production.

[0009] The transfer lead screw is arranged in parallel between two sets of transfer guide rails. The blanking and loading mechanism is sleeved on the transfer lead screw through a nut set. The second driving motor drives the transfer lead screw to drive the blanking and loading mechanism to move along the length direction of the transfer lead screw for loading and unloading. Due to the parallel arrangement of the transfer lead screw and the transfer guide rails and the balanced force on the blanking and loading mechanism, the equipment has less wear during long-term operation, which helps to reduce the maintenance cost and replacement frequency of the equipment.

[0010] The blanking and loading mechanism includes a transfer flat plate, a first side plate and a second side plate vertically arranged on both sides of the transfer flat plate. Two sets of identical rotating components are arranged on the inner sides of the first side plate and the second side plate. The transfer flat plate serves as the main bearing surface for supporting and fixing the plate to be blanked. The vertically arranged first side plate and second side plate provide additional lateral support, enhancing the stability and rigidity of the entire loading mechanism. This stable loading structure helps to ensure that the plate does not shake or tilt during movement. Two sets of identical rotating components are arranged on the inner sides of the first side plate and the second side plate. These components (such as rollers, bearings, etc.) enable the blanking and loading mechanism to have the function of rotation or revolution in specific situations. This flexibility is particularly important for handling plates that need to be adjusted in direction or angle, which can simplify the loading and unloading process and improve production efficiency.

[0011] The rotating component includes a gear set, a belt arranged on the gear set, and a third driving motor that drives the gear set to drive the belt to rotate. The gear set, as a transmission mechanism, has the characteristics of high transmission accuracy and stable transmission ratio. Through the transmission of the gear set, it can ensure that the belt rotates precisely at a predetermined speed and direction, thereby realizing the precise transmission of the plate. The third driving motor, as the power source, drives the gear set and then drives the belt to rotate. The precise control of the motor makes the entire rotation process smoother, more reliable, and easier to achieve automatic control.

[0012] The pushing mechanism, the moving table, and the blanking and loading mechanism are arranged in the same horizontal direction. The horizontal layout helps to reduce the positioning error of the plate caused by height difference or angle deviation. Each mechanism works together on the same horizontal plane, which can ensure the stability and accuracy of the plate during transfer. Arranging each mechanism in the same horizontal direction can make the layout of the entire equipment more compact. This compact layout helps to save the space in the production workshop and improve the space utilization rate. At the same time, the compact layout also helps to reduce the interference and collision risks between equipment.

[0013] The blanking and loading mechanism is provided with loading and unloading sensors at both ends. When an external plate is pushed to the blanking and loading mechanism by the pusher mechanism, the loading and unloading sensors at both ends are used to sense the external plate and then feedback to the system for loading and unloading. The loading and unloading sensors can detect in real time whether there is an external plate on the blanking and loading mechanism. When the pusher mechanism pushes the plate to the designated position, the sensors can quickly sense the arrival of the plate. Once the plate is sensed, the sensors will immediately feedback this information to the control unit of the system. This accurate feedback mechanism ensures that the equipment can make corresponding operation adjustments according to the real-time situation. Through the real-time detection and feedback of the sensors, the equipment can automatically start or adjust the loading and unloading process. This avoids manual intervention and waiting time, improves production efficiency, and ensures the continuity and stability of the production line.

[0014] The automatic loading and unloading equipment further includes a control system and a three-color lamp arranged on the base. The three-color lamp is electrically connected to the control system. When the control system detects a change in the operating state of the equipment or a fault occurs, it will immediately give feedback to the operator through the three-color lamp. This real-time feedback mechanism helps the operator quickly understand the current situation of the equipment and take corresponding measures.

[0015] The beneficial effects of the present utility model: The first driving motor drives the up and down moving screw rod group to drive the external storage board box on the moving platform to move up and down. The pusher mechanism is arranged on one side of the moving platform. As the external storage board box on the moving platform moves up or down, the pusher mechanism sequentially pushes the external plates in the external storage board box for loading. The box body plates adopt automatic loading and unloading, realizing the automatic loading and unloading process of PCB plates. This design not only improves production efficiency, ensures product quality, but also reduces labor intensity and enhances safety. It is one of the indispensable important equipment in modern industrial production. Description of the Drawings

An external board storage box 7 for storing external board parts is placed on the moving table 6. The moving table 6 is in lifting and matching connection with the base 1. The first driving motor 5 drives the up and down moving lead screw group 4 to drive the external board storage box 7 on the moving table 6 to move up and down; the pushing mechanism 3 is fixedly provided on the base 1, and the pushing mechanism 3 is used to push out the external board parts in the storage box 7 for loading.

[0024] The external board storage box 7 is placed on the moving table 6 and fixed. The first driving motor 5 is started to drive the up and down module 2 to work, so that the moving table 6 and the external board storage box 7 rise to the designated position. The pushing mechanism 3 is controlled according to signals or programs to sequentially push the board parts in the external board storage box 7 to the next process. After a box of board parts is pushed, another external board storage box 7 filled with board parts is replaced in front of the pushing mechanism 3 to continue pushing the board parts, and the whole process is cycled until all board parts are processed. Automated operation means that the machine can continuously and quickly complete the loading and unloading process of board parts with little or no human intervention, thus significantly improving the overall efficiency of the production line.

[0025] The mobile station 6 includes a support plate 9 and multiple groups of limit plates 11 arranged on the support plate 9. A clamping plate 12 is provided on the side away from the limit plates 11. The limit plates 11 and the clamping plate 12 are used to clamp an external storage box 7. The clamping plate 12 can be a spring piece. The elastic buffering effect of the spring piece can reduce the vibration and impact generated during the movement of the storage box, protect the plate parts from damage, and reduce the noise generated by the equipment due to vibration. Through the combined action of the limit plates 11 and the clamping plate 12, the external storage box 7 can be firmly clamped on the mobile station 6. This firm clamping method not only ensures that the storage box will not shake or fall off during the movement, but also improves the stability and safety of the entire loading and unloading process. The design of multiple groups of limit plates 11 allows the mobile station 6 to adapt to external storage boxes 7 of different sizes and shapes. By adjusting the position or quantity of the limit plates 11, storage boxes of various specifications can be flexibly clamped, thereby improving the versatility and adaptability of the equipment. By automatically clamping and releasing the external storage box 7, the operator can replace the storage box more conveniently without manually fixing or adjusting the position of the storage box. This not only simplifies the operation process, but also reduces manual intervention and potential operation errors.

At the same time, the loading mechanism can also be quickly replaced and adjusted to adapt to different types of plate parts.

The blanking loading mechanism 15 moves up and down for loading and unloading by sliding on the two groups of transfer guide rails 16 and moving along the direction of the two groups of transfer guide rails 16. The double-guide rail design disperses the pressure and friction of the blanking loading mechanism 15 during the movement, reducing the wear degree of the guide rails and the loading mechanism. This helps to extend the service life of the equipment and reduce the maintenance cost. The transfer lead screw 17 drives the blanking loading mechanism 15 to achieve precise movement through the second drive motor 18. The lead screw drive has the characteristics of high precision, high stability and high load capacity, and can meet the requirements for precise position control in automated production.

[0028] The transfer lead screw 17 is arranged in parallel between two sets of transfer guide rails 16.
