[0002] Printed circuit boards are used in various electronic products, such as televisions, computers, mobile phones, electronic measuring instruments, etc. With the advancement of technology, printed circuit boards tend to be designed in a miniature and high-density direction, making the processing technology complicated. Therefore, printed circuit boards need to be moved at various processing nodes in the production line, and will be continuously transported and delivered in the production line. The existing technology is to transport printed circuit boards by carts, and move the printed circuit boards on the carts to the processing equipment at various processing nodes by manpower to continue to perform subsequent processes. However, manual transportation not only consumes labor costs, but also employees are more likely to be injured due to careless operation during manual transportation, and affect the processing procedures and production quality of printed circuit boards. In addition, if a moving device is installed on the cart, the cart will be too heavy, causing inconvenience in movement. Utility Model Content

[0003] The main purpose of the utility model is to solve the problems that the existing transport by manpower using a cart is insufficient and the cart is not suitable for installing a transport device.

[0004] In order to solve the above problems, the utility model discloses a loading and unloading cart without kinetic energy, which is used to transport a carrier carrying at least one printed circuit board and can be connected to a processing equipment. The loading and unloading cart includes a mobile carrier, a transmission assembly and a conveying assembly.

The transmission rod includes an end for coupling a driving unit of the processing equipment. The conveying assembly includes a conveying wheel group exposed on the main body and a plurality of second magnetic elements connected to the conveying wheel group and rotating with the conveying wheel group. The conveying wheel group is used to carry the carrier. When the trolley moves to the processing equipment and the end of the transmission rod is coupled to the driving unit of the processing equipment, the driving unit drives the transmission rod to rotate around the axial direction, and the first magnetic element drives the second magnetic element and the conveying wheel group connected to the second magnetic element to rotate, so that the carrier on the conveying wheel group is detached from the trolley.

[0005] In one embodiment, the transmission rod includes a locking portion protruding from a front end of the body, and the locking portion can contact and lock the driving unit.

[0006] In one embodiment, the moving wheel set of the moving vehicle is configured to allow the moving vehicle to move along a first moving direction.

[0007] In one embodiment, the conveying wheel assembly includes a plurality of wheel rods that carry and drive the carrier to move along a second moving direction.

[0008] In one embodiment, the moving wheel group of the mobile carrier is configured to allow the mobile carrier to move along a first moving direction, and the conveying wheel group includes a plurality of wheel rods that carry and drive the carrier to move along a second moving direction, and the first moving direction is substantially the same as the second moving direction.

[0009] In one embodiment, a rotation direction of the transmission rod is perpendicular to a rotation direction of the conveying wheel assembly.

[0010] In one embodiment, a height of the transmission rod from the ground is substantially the same as a height of the driving unit from the ground.

[0011] In one embodiment, a stopping component is further included, which is located above the conveying component and is disposed at a front end of the main body and can limit the carrier from separating from the conveying component along a moving direction.

[0012] In one embodiment, the stopping assembly includes a first stopping member and a second stopping member, and the first stopping member and the second stopping member are disposed on both sides of the front end.

[0013] In one embodiment, the loading and unloading cart switches between a non-connected state and a connected state. In the non-connected state, the stopping component restricts the carrier from disengaging from the conveying component along the travel direction. In the connected state, the stopping component does not restrict the carrier from moving along the travel direction.

[0046] The structural principle and working principle of the utility model are described in detail below in conjunction with the accompanying drawings:

[0047] The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Unless the context indicates otherwise, the singular forms "a", "an" and "the" used herein may also include plural forms.

[0048] Directional terms used herein, such as up, down, left, right, front, back and their derivatives or synonyms, refer to the orientation of elements in the drawings and are not intended to limit the present invention unless the context clearly states otherwise.

[0049] See also Figure 1 and Figure 2 The utility model discloses a loading and unloading cart 1 without a kinetic energy source, the loading and unloading cart 1 is used to transport a carrier 2 and can be connected to a processing device 3, the carrier 2 carries at least one printed circuit board 2a, and the processing device 3 has a driving unit 3a. The loading and unloading cart 1 can be in a non-connected state (such as Figure 1 and Figure 2 as shown) and a connected state (as shown Figure 3 As shown), when the loading and unloading cart 1 and the processing equipment 3 are in the connected state, the carrier 2 is transported to the processing equipment 3 for processing.

[0050] The loading and unloading cart 1 includes a moving carrier 10, a transmission assembly 20, a conveying assembly 30 and a stopping assembly 40. In the present invention, it is defined that the loading and unloading cart 1 does not have any kinetic energy source that can drive or control the movement of the carrier 2 on the loading and unloading cart 1, such as an engine, a motor, an engine or any other machine that converts potential energy into kinetic energy to do work, such as chemical energy in fuel, electrical energy, etc.

[0051] The transmission assembly 20, the conveying assembly 30 and the stopping assembly 40 are disposed on the mobile carrier 10, and the mobile carrier 10 moves along a travel direction D1 to connect with the processing equipment 3. In the present utility model, connection may refer to a front end of the mobile carrier 10 and a receiving end of the processing equipment 3 being connected and fixed to each other, and the two may be directly connected or indirectly connected via other elements. Connection may also be a connection state that allows the carrier 2 on the mobile carrier 10 to move to the processing equipment 3. For example, there is a gap between a part of the mobile carrier 10 used to carry the carrier 2 and the processing equipment 3, but the carrier 2 can still be moved from the mobile carrier 10 to the processing equipment 3, which is also considered to be in a connection relationship.

[0052] The mobile carrier 10 includes a body 11 and a moving wheel set 12, the moving wheel set 12 is disposed below the body 11, and allows the loading and unloading cart 1 to move between processing nodes of the production line, such as connecting the processing equipment 3 along the travel direction D1. In one example, the body 11 is assembled by a plurality of frames, and the frames can be made of aluminum alloy or stainless steel.

[0053] In this embodiment, the body 11 has a front end 111 and a rear end 112, and the transmission assembly 20 is disposed on the body 11. The transmission assembly 20 includes a transmission rod 21 and a plurality of first magnetic elements 22. The transmission rod 21 is disposed along the travel direction D1 and can be coupled to a connection portion 3b of the drive unit 3a of the processing equipment 3. For example, the transmission rod 21 is horizontally extended from the front end 111 to the rear end 112, and for the purpose of connecting the mobile carrier 10 to the processing equipment 3, a height L1 of the transmission rod 21 from the ground G is close to or the same as a height L2 of the connection portion 3b from the ground G. The transmission rod 21 includes a locking portion 211, which is arranged on a side close to or protruding from the front end 111 and is an end portion of the transmission rod 21. The locking portion 211 can contact and lock the connecting portion 3b of the driving unit 3a. The driving unit 3a is used to drive the transmission rod 21 to rotate, and the transmission rod 21 is used to drive the conveying component 30.

[0054] like Figure 1 and Figure 2 As shown, a plurality of the first magnetic elements 22 are disposed and fixed on the transmission rod 21 , and rotate with the transmission rod 21 . In this example, a plurality of the first magnetic elements 22 are distributed on the transmission rod 21 at equal intervals.

[0055] The conveying assembly 30 is disposed on the main body 11 and is used to carry the carrier 2. The conveying assembly 30 includes a conveying wheel group 31 and a plurality of second magnetic elements 32. The conveying wheel group 31 is exposed on the main body 11 and carries the carrier 2. The conveying wheel group 31 includes a plurality of wheel rods 311. The wheel rods 311 are arranged at intervals along the travel direction D1 and can drive the carrier 2 to move along the travel direction D1 when rotating. A wheel center line 311a of the wheel rod 311 is perpendicular to the travel direction D1.

[0056] The second magnetic element 32 is connected and fixed to the conveying wheel set 31, and the second magnetic element 32 is configured to be magnetically coupled with the first magnetic element 22. In detail, at least part of the wheel rod 311 of the conveying wheel set 31 is provided with one or more second magnetic elements 32. In this example, all the wheel rods 311 of the conveying wheel set 31 are provided with one second magnetic element 32. The second magnetic element 32 on the wheel rod 311 is arranged corresponding to the first magnetic element 22 in position, and the second magnetic element 32 is magnetically coupled to the first magnetic element 22. In this way, when the transmission rod 21 is rotated, the first magnetic element 22 on the transmission rod 21 also rotates, thereby driving the second magnetic element 32 on the wheel rod 311 to rotate, thereby driving the wheel rod 311 to rotate, so that the carrier 2 moves along the travel direction D1.

[0057] In this example, a rotation direction of the first magnetic element 22 of the transmission component 20 is perpendicular to a rotation direction of the second magnetic element 32 of the conveying component 30 .

[0058] The moving wheel group 12 of the moving vehicle 10 is configured to allow the moving vehicle 10 to move along a first moving direction, and the wheel rod 311 of the conveying wheel group 31 carries and drives the carrier 2 to move along a second moving direction. The first moving direction is substantially the same as the second moving direction, and the first moving direction and the second moving direction are the same as the travel direction D1 in this embodiment.

[0059] The stopper assembly 40 is located above the conveying assembly 30 and disposed at the front end 111 of the body 11 to block the movement of the carrier 2 on the mobile carrier 10. When the loading and unloading cart 1 is in the non-engaged state, the stopper assembly 40 is higher than a plane (a stopper position) supporting the carrier 2, and limits the movement of the carrier 2 along the travel direction D1, thereby preventing the carrier 2 from accidentally falling off the loading and unloading cart 1 when the loading and unloading cart 1 is not yet engaged with the processing equipment 3.

[0060] See also Figure 3 , and when the loading and unloading cart 1 is connected to the processing equipment 3, the stopper assembly 40 will move downward without blocking the carrier 2 from moving along the travel direction D1. In this example, the stopper assembly 40 includes a first stopper 41 and a second stopper 42, and the first stopper 41 and the second stopper 42 are arranged on the left and right sides of the front end 111. In the connected state, the first stopper 41 and the second stopper 42 can be respectively converted from the stop position to an open position by a connecting rod mechanism, so that the first stopper 41 and the second stopper do not block the carrier 2, so that the carrier 2 has a smooth path to enter the processing equipment 3 along the travel direction D1.

[0061] In summary, the loading and unloading cart of the utility model does not need to be equipped with kinetic energy, but the driving unit of the processing equipment drives the transmission component to rotate, and then the first magnetic element drives the second magnetic element and the wheel rod to rotate, so as to drive the carrier to move along the conveying direction to the processing equipment for processing. The structure and design of the loading and unloading cart can be simplified, and the cost and energy usage can be reduced. The user only needs to move the loading and unloading cart to the processing equipment and confirm that the locking part of the transmission component is locked to the driving unit, and the carrier can be automatically transported to the processing equipment, achieving the purpose of semi-automation, which helps to reduce manpower and reduce the risk of occupational accidents.

[0062] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
