Description

Technical Field

[0001] The utility model relates to the technical field of automatic loading and unloading, and particularly discloses a feeding and discharging mechanism for stacked non-contact materials. Background Art

[0002] In the production and transportation process of PCB boards, the traditional method is to place them in a board storage box for easy management and movement. However, in the prior art, taking out PCB boards from the board storage box for unloading mainly relies on manual methods. This manual unloading method not only has low efficiency, restricting the overall speed of the production line, but also is prone to causing physical damage to the PCB boards during the transfer process, such as scratches, bending or electrostatic discharge, etc., which will have an adverse impact on the subsequent processing quality and product performance. Content of the Utility Model

[0003] To achieve the above object, a feeding and discharging mechanism for stacked non-contact materials of the utility model includes a loading mechanism, an unloading mechanism, a loading platform, and an up-and-down moving lead screw group for driving the loading platform to move up and down. The loading mechanism, the loading platform, and the unloading mechanism are arranged in the same horizontal direction. The loading platform is used to carry a board storage box, and the board storage box is used to accommodate a plurality of external board pieces arranged at intervals in a stacked manner. The loading platform is connected with the up-and-down moving lead screw group in a lifting and matching manner. The loading mechanism pushes the external board pieces in the board storage box onto the unloading mechanism one by one for unloading as the loading platform intermittently rises and falls. When the loading mechanism is in the starting position and waits for the board storage box on the loading platform to rise to an appropriate height, the board storage box is lifted by the up-and-down moving lead screw group to align with the loading mechanism. Then the loading mechanism is started to push out the external board pieces in the board storage box and smoothly transfer them onto the unloading mechanism. This feeding and discharging mechanism reduces the need for manual operation and speeds up the material handling speed through an automated and non-contact material transfer method, thus significantly improving the production efficiency. The non-contact design reduces the friction and collision of materials during the transfer process, reducing the risk of damage. At the same time, it also reduces the possibility of pollution caused by manual contact, ensuring the quality and cleanliness of the board piece materials.

[0004] The loading mechanism includes a first support frame, a pushing component arranged on the first support frame, and a first driving motor. The first driving motor drives the pushing component to push out the external board pieces in the board storage box. The first support frame serves as the basic framework of the loading mechanism, providing a stable support platform. The pushing component can be flexibly selected according to actual needs, enabling the loading mechanism to adapt to external board pieces of different sizes and weights.

[0005] The pushing component includes a gear guide rail and a gear rotating shaft. The gear rotating shaft is arranged in cooperation with the first driving motor. The first driving motor drives the gear rotating shaft to rotate to drive the gear guide rail to push forward and backward. When it is necessary to push out the external plate in the storage box, the first driving motor starts and drives the gear rotating shaft to rotate. The rotation of the gear rotating shaft drives the gear guide rail to push forward and backward through the meshing of the gear and the gear guide rail. The pushing action of the gear guide rail smoothly and accurately pushes out the external plate in the storage box and transfers it to the blanking mechanism. The design of the gear guide rail ensures the accuracy and stability during the pushing process, avoiding damage or deviation of the plate.

[0006] The up-and-down moving screw rod group includes a second support frame, an up-and-down screw rod guide rail arranged on the second support frame, and a second driving motor for driving the up-and-down screw rod guide rail to move up and down. As the main structure of the up-and-down moving screw rod group, the second support frame provides a stable support platform, which ensures that the up-and-down screw rod guide rail and the second driving motor can be stably installed and operated, and at the same time bears various forces generated during the lifting process. When it is necessary to lift the loading table, the second driving motor starts and drives the screw rod to rotate. The rotation of the screw rod drives the guide rail to move up and down through the cooperation of the thread and the up-and-down screw rod guide rail, and the up-and-down movement of the up-and-down screw rod guide rail further drives the loading table to lift, so as to align or separate from the loading mechanism and the blanking mechanism of the external plate. The design of the up-and-down screw rod guide rail and the support structure can bear the weight of the loading table and the materials on it, ensuring the safe operation of the equipment.

[0007] The loading table is sleeved on the up-and-down screw rod guide rail through a nut. The loading table includes a moving block, multiple groups of side plates arranged on the moving block, and a spring clamping plate is arranged on one side far away from the side plates. The side plates and the spring clamping plate are used to clamp the storage box. The combination of the side plates and the spring clamping plate ensures the stable clamping of the storage box on the loading table, preventing sliding or falling during the lifting process. The design of multiple groups of side plates and spring clamping plates can be adjusted according to storage boxes of different sizes and shapes, enhancing the adaptability and flexibility of the equipment.

[0008] The blanking mechanism includes a third support frame, a reciprocating screw rod group arranged on the third support frame, a bearing platform slidably arranged on the reciprocating screw rod group, and a third driving motor for driving the reciprocating screw rod group to rotate. As the main structure of the blanking mechanism, the third support frame provides a stable support platform, which ensures that the reciprocating screw rod group, the bearing platform and the third driving motor can be stably installed and operated, and at the same time bears various forces generated during the blanking process. When the loading mechanism pushes out the external plate and transfers it to the blanking mechanism, the bearing platform receives these plates. The third driving motor starts and drives the reciprocating screw rod group to rotate. Through the cooperation of the screw rod and the nut, the bearing platform is driven to move reciprocally. The combination of the reciprocating screw rod group and the bearing platform realizes the efficient and stable transmission of the external plate, improving the overall efficiency of the production line.

[0009] The loading platform includes a flat tabletop, a first plate member and a second plate member vertically arranged on both sides of the flat tabletop. Two sets of identical rotating components are provided on the inner sides of the first plate member and the second plate member. The rotating components include a gear set, a rotating belt arranged on the gear set, and a fourth driving motor for driving the gear set to drive the rotating belt to rotate. When the external plate members are transported onto the loading platform, they are placed on the loading platform for support. The fourth driving motor drives the rotating components to rotate to drive the external plate members to be transported to the designated position. When the external plate members are completely transported onto the loading platform, the reciprocating lead screw group drives the plate members on the loading platform to be unloaded.

[0010] The unloading mechanism further includes a drag chain guide rail group, which is arranged in parallel with the reciprocating lead screw group. The drag chain guide rail group is driven by a third driving motor, and the loading platform is arranged on the drag chain guide rail group via a mounting base. The drag chain guide rail group and the reciprocating lead screw group are arranged in parallel, and they jointly provide a stable and controllable moving path for the loading platform. When the third driving motor drives the reciprocating lead screw group to rotate, the loading platform not only moves back and forth along the lead screw direction, but also slides smoothly and stably along the drag chain guide rail group. The drag chain guide rail group provides additional support and guidance for the loading platform, enhancing the stability of the equipment during the transportation process. Since the loading platform is guided and supported by the drag chain guide rail group during the moving process, the wear and friction generated by direct contact with the reciprocating lead screw group are reduced.

[0011] The board storage box is a hollow cuboid shape. The board storage box has an accommodation cavity for accommodating board members. Accommodation blind grooves are provided on the side walls on both the left and right sides of the accommodation cavity. The accommodation blind grooves penetrate the board storage box along the front-back direction of the board storage box. The two ends of the board members away from each other are respectively located in the accommodation blind grooves on the side walls on both the left and right sides of the accommodation cavity. The loading mechanism is used to push the middle part of the board members in the accommodation cavity. The board members are stably and orderly stored by embedding their two ends into the accommodation blind grooves on the side walls of the board storage box, reducing the movement or damage of the board members during the storage process. The hollow cuboid design of the board storage box and the storage method of the board members effectively utilize the storage space, enabling more board members to be stored in a limited space. The loading mechanism pushes the external board members in the board storage box onto the unloading mechanism one by one as the loading table intermittently rises and falls. Combined with the accommodation blind grooves of the board storage box, it ensures the continuous and orderly loading of the board members, improving the production efficiency.

[0012] The feeding mechanism further includes a housing sleeved outside the pushing component. The housing is a structure that surrounds or at least partially surrounds the pushing component and is usually made of metal, plastic, or other durable materials. It is closely sleeved outside the pushing component to form a protective layer or shielding layer, isolating the internal mechanism of the pushing component from the external environment. The housing also plays a role in safety isolation. During the operation of mechanical equipment, the internal moving parts may generate high-speed rotation, high temperature, or other potential risk factors. The design of the housing can prevent operators or external objects from contacting these dangerous areas, thus ensuring personal and equipment safety. The housing not only protects the internal mechanism from external pollution and damage but also improves the safety of the equipment, reduces noise and vibration, and beautifies the appearance of the equipment. These functions jointly ensure the stable operation and long-term reliability of the feeding mechanism.

[0013] Both ends of the carrying platform are provided with loading and unloading sensors. The loading and unloading sensors can detect the presence or absence of materials on the carrying platform in real time, as well as the specific position of the materials. This is crucial for determining whether the materials have reached the correct position, whether further transmission is required, or for the next step of processing. Once the sensor detects a change in the state of the materials (such as the materials being in place, missing, or displaced), it will immediately send a signal to the control system. The control system triggers corresponding control logics based on these signals, such as starting or stopping transmission, adjusting the transmission speed, triggering an alarm, etc. By integrating the loading and unloading sensors, the carrying platform can achieve a higher level of automated control. It can automatically adjust the transmission process according to the actual state of the materials, reducing the possibility of manual intervention and misoperation, thereby improving production efficiency and product quality.

[0014] The beneficial effects of the present utility model: The stacked non-contact material feeding and discharging mechanism integrates a feeding mechanism, a discharging mechanism, a feeding table, and an up-and-down moving screw rod group for driving the vertical movement of the feeding table. This design cleverly arranges these components in the same horizontal direction. The feeding table is used to place the storage board box and realizes lifting adjustment through close cooperation with the up-and-down moving screw rod group. During the operation process, as the feeding table rises and falls, the feeding mechanism can accurately push the external board pieces in the storage board box onto the discharging mechanism to complete the discharging operation. This mechanism significantly reduces the physical contact and potential wear of the materials during the feeding and discharging process, thus effectively protecting the surface quality of the materials. At the same time, it realizes the efficient and automated processing of the external board pieces in the storage board box, improving the overall production efficiency and automation level.

Specific embodiments

[0022] For the convenience of those skilled in the art to understand, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present utility model.

[0023] Please refer to Figures 1 to 5 As shown, a feeding and discharging mechanism for stacked non-contact materials of the present utility model includes a loading mechanism 1, an unloading mechanism 2, a loading table 3, and an up-and-down moving screw rod group 4 for driving the up-and-down movement of the loading table 3. The loading mechanism 1, the loading table 3, and the unloading mechanism 2 are arranged in the same horizontal direction. A plate storage box 5 is placed on the loading table 3. The loading table 3 is in lifting and matching connection with the up-and-down moving screw rod group 4. The loading mechanism 1 pushes the external plate members in the plate storage box 5 onto the unloading mechanism 2 for unloading as the loading table 3 rises and falls. When the loading mechanism 1 is in the starting position and waits for the plate storage box 5 on the loading table 3 to rise to an appropriate height, the plate storage box 5 is lifted by the up-and-down moving screw rod group 4 along with the loading table 3 until it is aligned with the loading mechanism 1. Then the loading mechanism 1 is activated to push out the external plate members in the plate storage box 5 and smoothly transfer them onto the unloading mechanism 2. This feeding and discharging mechanism reduces the need for manual operation through an automated and non-contact material transfer method, speeds up the material processing speed, and thus significantly improves production efficiency. The non-contact design reduces friction and collision of materials during the transfer process, reducing the risk of damage. At the same time, it also reduces the possibility of contamination caused by manual contact, ensuring the quality and cleanliness of the plate materials.

[0024] The feeding mechanism 1 includes a first support frame 6, a pushing component 7 arranged on the first support frame 6, and a first driving motor 8. The first driving motor 8 drives the pushing component 7 to push out the external plate in the storage box 5. The first support frame 6 serves as the basic framework of the feeding mechanism 1 and provides a stable support platform. The pushing component 7 can be flexibly selected according to actual needs, enabling the feeding mechanism 1 to adapt to external plates of different sizes and weights.

[0025] The pushing component 7 includes a gear guide rail 9 and a gear rotating shaft 11. The gear rotating shaft 11 is arranged in cooperation with the first driving motor 8. The first driving motor 8 drives the gear rotating shaft 11 to rotate to drive the gear guide rail 9 to push forward and backward. When it is necessary to push out the external plate in the storage box 5, the first driving motor 8 starts and drives the gear rotating shaft 11 to rotate. The rotation of the gear rotating shaft 11 drives the gear guide rail 9 to push forward and backward through the meshing of the gear with the gear guide rail 9. The pushing action of the gear guide rail 9 smoothly and accurately pushes out the external plate in the storage box 5 and transfers it to the discharging mechanism 2. The design of the gear guide rail 9 ensures the accuracy and stability during the pushing process and avoids damage or deviation of the plate.

[0026] The up-and-down moving screw rod group 4 includes a second support frame 12, an up-and-down screw rod guide rail 13 arranged on the second support frame 12, and a second driving motor 14 for driving the up-and-down screw rod guide rail 13 to move up and down. As the main structure of the up-and-down moving screw rod group 4, the second support frame 12 provides a stable support platform, which ensures that the up-and-down screw rod guide rail 13 and the second driving motor 14 can be stably installed and operated, and at the same time bears various forces generated during the lifting process. When it is necessary to lift or lower the feeding table 3, the second driving motor 14 starts and drives the screw rod to rotate. The rotation of the screw rod drives the guide rail to move up and down through the cooperation of the thread with the up-and-down screw rod guide rail 13. The up-and-down movement of the up-and-down screw rod guide rail 13 further drives the feeding table 3 to move up and down, realizing alignment or separation from the feeding mechanism 1 and the discharging mechanism 2 of the external plate. The design of the up-and-down screw rod guide rail 13 and the support structure can bear the weight of the feeding table 3 and the materials on it, ensuring the safe operation of the equipment.

[0027] The feeding table 3 is sleeved on the up-and-down screw rod guide rail 13 through a nut. The feeding table 3 includes a moving block 15 and multiple groups of side plates 16 arranged on the moving block 15. A spring clamping plate 17 is provided on one side away from the side plates 16. The side plates 16 and the spring clamping plate 17 are used to clamp the storage box 5. The combination of the side plates 16 and the spring clamping plate 17 ensures the stable clamping of the storage box 5 on the feeding table 3 and prevents sliding or falling during the lifting process. The design of multiple groups of side plates 16 and the spring clamping plate 17 can be adjusted according to the storage box 5 of different sizes and shapes, enhancing the adaptability and flexibility of the equipment.

[0028] The blanking mechanism 2 includes a third support frame 18, a reciprocating lead screw group 19 arranged on the third support frame 18, a bearing platform 21 slidably arranged on the reciprocating lead screw group 19, and a third driving motor 22 for driving the reciprocating lead screw group 19 to rotate. As the main structure of the blanking mechanism 2, the third support frame 18 provides a stable support platform, which ensures that the reciprocating lead screw group 19, the bearing platform 21, and the third driving motor 22 can be stably installed and operated, and at the same time bears various forces generated during the blanking process. When the feeding mechanism 1 pushes out and transports the external plate to the blanking mechanism 2, the bearing platform 21 receives these plates. The third driving motor 22 starts and drives the reciprocating lead screw group 19 to rotate. Through the cooperation of the lead screw and the nut, the bearing platform 21 is driven to move reciprocally. The combination of the reciprocating lead screw group 19 and the bearing platform 21 realizes the efficient and stable transmission of the external plate, improving the overall efficiency of the production line.

[0029] The bearing platform 21 includes a flat tabletop 23, a first plate member 24 and a second plate member 25 vertically arranged on both sides of the flat tabletop 23. Two sets of identical rotating components 26 are arranged on the inner sides of the first plate member 24 and the second plate member 25. The rotating component 26 includes a gear set 27, a rotating belt 28 arranged on the gear set 27, and a fourth driving motor 29 for driving the gear set 27 to drive the rotating belt 28 to rotate. When the external plates are transported onto the bearing platform 21, they are placed on the bearing platform 21 for support. The fourth driving motor 29 drives the rotating component 26 to rotate to drive the external plates to be transported to the designated position. When the external plates are completely transported onto the bearing platform 21, the reciprocating lead screw group 19 drives the plates on the bearing platform 21 to be blanked.

[0030] The blanking mechanism 2 further includes a drag chain guide rail group 31. The drag chain guide rail group 31 is arranged in parallel with the reciprocating lead screw group 19. The drag chain guide rail group 31 is driven by the third driving motor 22, and the bearing platform 21 is arranged on the drag chain guide rail group 31 via an installation base 32. The drag chain guide rail group 31 is arranged in parallel with the reciprocating lead screw group 19, and they jointly provide a stable and controllable moving path for the bearing platform 21. When the third driving motor 22 drives the reciprocating lead screw group 19 to rotate, the bearing platform 21 not only moves reciprocally along the lead screw direction, but also slides smoothly and stably along the drag chain guide rail group 31. The drag chain guide rail group 31 provides additional support and guidance for the bearing platform 21, enhancing the stability of the equipment during the transmission process. Since the bearing platform 21 is guided and supported by the drag chain guide rail group 31 during the moving process, the wear and friction generated by direct contact with the reciprocating lead screw group 19 are reduced.

[0031] The storage box 5 is a hollow cuboid shape. The storage box 5 has a receiving cavity for accommodating the plate members. On the side walls on both the left and right sides of the receiving cavity, receiving blind grooves are provided. The receiving blind grooves penetrate through the storage box 5 in the front-back direction of the storage box 5. The two ends of the plate members away from each other are respectively located in the receiving blind grooves on the side walls on both the left and right sides of the receiving cavity. The feeding mechanism 1 is used to push the middle part of the plate members in the receiving cavity. The plate members are stably and orderly stored by embedding their two ends into the receiving blind grooves on the side walls of the storage box, reducing the movement or damage of the plate members during storage. The hollow cuboid design of the storage box 5 and the storage method of the plate members enable the effective use of the storage space, and more plate members can be stored in a limited space. The feeding mechanism pushes the external plate members in the storage box onto the discharging mechanism one by one for discharging with the intermittent lifting of the feeding table. Combined with the receiving blind grooves of the storage box, it ensures the continuous and orderly feeding of the plate members and improves the production efficiency.

[0032] Both ends of the carrying platform 21 are provided with loading and unloading sensors 34. The loading and unloading sensors 34 can detect the presence or absence of materials on the carrying platform 21 in real time, as well as the specific positions of the materials. This is crucial for determining whether the materials have arrived, whether further transmission is required, or for the next step of processing. Once the sensor detects a change in the state of the materials (such as the materials arriving, missing, or being displaced), it will immediately send a signal to the control system. The control system triggers the corresponding control logic based on these signals, such as starting or stopping transmission, adjusting the transmission speed, triggering an alarm, etc. By integrating the loading and unloading sensors 34, the carrying platform 21 can achieve a higher level of automated control. It can automatically adjust the transmission process according to the actual state of the materials, reducing the possibility of manual intervention and misoperation, thereby improving the production efficiency and product quality.

[0033] The remaining parts of this embodiment are the same as those of Embodiment 1. For the features not explained in this embodiment, the explanations of Embodiment 1 are adopted and will not be elaborated here.

[0034] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present utility model.
