[0028] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein the same or like reference numerals and letters throughout the several views denote the same or like elements or components.

[0029] Reference is made below to Figure 1-Figure 3 A transfer device 100 according to an embodiment of the present application is described below.

[0030] As Figure 1-Figure 3As shown, according to the transfer device 100 of the embodiment of the present application, the transfer device 100 comprises a moving part 1, a lifting mechanism 2 and a carrying part 3. The moving part 1 is provided with wheels 11. The lifting mechanism 2 is arranged on the moving part 1 and is provided with a moving end 21 which can be selectively moved in the height direction. The carrying part 3 is connected with the moving end 21 and is adapted to be moved in the height direction under the drive of the moving end 21. A plurality of prongs 31 are arranged on the carrying part 3 in the width direction and extend away from the carrying part 3. The prongs 31 are adapted to be inserted into the corresponding slots in the material placing table and move with the carrying part 3.

[0031] According to the transfer device 100 of the embodiment of the present application, the moving part 1 is provided with wheels 11, so that the transfer device 100 can be moved between different positions, facilitating the transfer of the PCB from one place to another. The lifting mechanism 2 is arranged on the moving part 1, providing the adjustment capability of the transfer device 100 in the height direction, so that the height can be adjusted according to different material placing table heights and operation requirements. The carrying part 3 is connected with the moving end 21, and the carrying part 3 can be moved in the height direction under the drive of the moving end 21. The carrying part 3 can be adjusted to a height matching the material placing table, ensuring the stability and accuracy of the cooperation between the prongs 31 on the carrying part 3 and the slots in the material placing table.

[0032] It can be understood that the moving end 21 of the lifting mechanism 2 can be adjusted according to the height of the material placing table, so that the carrying part 3 can be at the same height level as the material placing table. When the carrying part 3 is consistent with the height of the material placing table, the prongs 31 inserted into the corresponding insertion slots in the material placing table can be more stable, solving the problem of inserting the prongs 31 from the edge to the bottom of the PCB during the transfer process, avoiding the contact of the prongs 31 with the edge of the PCB. The prongs 31 do not contact the PCB during the process of entering the material placing table, and the prongs 31 are in surface-to-surface contact with the PCB after being lifted by the lifting mechanism 2, reducing the damage to the PCB and avoiding the friction between the PCB and the edge or other parts of the material placing table during the transfer process due to the height difference. The plurality of prongs 31 are arranged in the width direction, providing multiple support points for the PCB. The dispersed support of multiple support points makes the PCB more evenly stressed during the transfer process. Compared with the traditional whole plane carrying method, the interval arrangement of the prongs 31 reduces the contact area between the PCB and the carrying part 3, thereby reducing the possibility of friction. The prongs 31 are inserted into the corresponding insertion slots in the material placing table, and the PCB is supported by the prongs 31 and guided by the insertion slots, so that it can be moved from the material placing table to the carrying part 3 of the transfer device 100, or from the carrying part 3 to another material placing table, avoiding friction with surrounding objects during the transfer process. Since the friction of the PCB is avoided, the damage to the PCB surface caused by friction, such as scratching and wear, is greatly reduced, the appearance damage of the PCB is reduced, the quality and reliability of the PCB are improved, the cost of maintenance or replacement due to damage is reduced, thereby achieving the beneficial effect of reducing the loss of PCB.

[0033] According to some embodiments of the present application, the transfer device 100 further comprises a guide part 4, which is arranged in parallel with the prongs 31 and is arranged on the carrying part 3. The end of the guide part 4 is provided with an inclined guide surface 41.

[0034] When the transfer device 100 approaches the discharge table to perform the transfer operation of the PCB board, the guide part 4 provides a guide for the tooth fork 31 to be inserted into the corresponding slot in the discharge table. Since the guide part 4 is arranged in parallel with the tooth fork 31 and the outer periphery of the end is provided with an inclined guide surface 41, in the process of the tooth fork 31 approaching the slot, the guide surface 41 first contacts the discharge table. The inclined guide surface 41 can guide the tooth fork 31 to align with the slot more accurately, ensuring that the tooth fork 31 can be smoothly inserted, avoiding collision or friction between the bearing part 3 and the discharge table due to inaccurate insertion of the tooth fork 31, thereby further reducing possible damage to the PCB board; at the same time, the guide part 4 also increases the stability of the transfer device 100 during the insertion and removal of the tooth fork 31, and ensures the smooth progress of the entire transfer process by guiding the tooth fork 31 to be inserted into the slot. The stable operation reduces the occurrence of accidents and reduces the risk of damage to the PCB board, thereby further reducing the loss of the PCB board.

[0035] In some embodiments of the present application, the guide portion 4 is constructed as a guide rod, and the tooth fork 31 is arranged between the two guide rods. The guide surfaces 41 arranged at the ends of the guide rods are arranged relative to each other. The length of the guide rod is greater than the length of the tooth fork 31. The tooth fork 31 is arranged between the two wire rods, so that when the tooth fork 31 is inserted into the slot, it is guided by the guide rods on both sides, further improving the accuracy and stability of the insertion. When the transfer device 100 approaches the unloading table, the guide rods on both sides can contact the unloading table at the same time, guiding the tooth fork 31 from two directions to prevent the tooth fork 31 from offset. The relatively arranged guide surfaces 41 are used to guide the guide rods to ensure that the guide rods are in smooth contact with the unloading table. At the same time, the longer guide rods can contact the unloading table in advance when inserted into the slot, providing earlier guidance for the insertion of the tooth fork 31. When the tooth fork 31 is pulled out, the guide rod can also maintain contact with the unloading table before the tooth fork 31 leaves the slot, ensuring a smooth extraction process.

[0036] According to the transfer device 100 of some embodiments of the present application, a contact portion 311 for supporting a transfer member is formed on the top surface of each tine 31 , and the contact portion 311 is configured as a flexible member.

[0037] When the PCB board is placed on the prongs 31, the flexible contact part 311 can play a buffering role. When the transfer device 100 moves or encounters bumps, the flexible contact part 311 can absorb the shock and reduce the relative movement between the PCB board and the prongs 31, thereby further reducing the friction frequency between the PCB board and other structures. Traditional rigid contact can cause friction between the PCB board and the prongs 31 during the process of shaking or moving, while the flexible contact part 311 avoids the friction caused by shaking and moving. At the same time, the flexible contact part 311 will not scratch or wear the surface of the PCB board. During the process of placing and taking out the PCB board, the flexible contact part 311 can avoid hard contact between the prongs 31 and the PCB board, and protect the surface quality of the PCB board.

[0038] According to the transfer device 100 of some embodiments of the present application, the plurality of tooth groove parts 32 are arranged at intervals in the width direction on the bearing part 3, and each tooth groove part 32 is formed with a receiving groove for receiving the prong 31. A plurality of prongs 31 are received in the corresponding tooth groove part 32 and are detachably connected with the tooth groove part 32.

[0039] The plurality of tooth groove parts 32 are arranged at intervals in the width direction, so that the prongs 31 can be flexibly adjusted in position according to PCB boards of different sizes. When facing PCB boards of different widths, the prongs 31 can be installed in the appropriate tooth groove part 32, ensuring that the prongs 31 can be accurately inserted into the insertion slots of the feeding table, while providing stable support for the PCB board. The appropriate support distance can avoid the PCB board from rubbing against surrounding objects due to shaking during the transfer process, reducing damage. For narrower PCB boards, the prongs 31 can be installed more concentratedly in the tooth groove part 32 near the center, so as to concentrate the support and reduce the possibility of shaking.

[0040] Further, the detachable connection of the prongs 31 and the tooth groove part 32 makes it convenient to replace the prongs 31 when they are damaged or worn. If the prongs 31 deform or wear during long-term use, they can be easily detached from the tooth groove part 32 and replaced with new prongs 31, without the need to replace the entire bearing part 3, thereby reducing maintenance costs. Timely replacement of damaged prongs 31 can ensure that the transfer device 100 always maintains good working condition, reducing the friction and damage of the PCB board caused by the prongs 31.

[0041] According to the transfer device 100 of some embodiments of the present application, the transfer device 100 further comprises a guard plate 5 connected with the bearing part 3 and arranged on one side of the prongs 31, and the extension direction of the guard plate 5 is parallel to the extension direction of the prongs 31.

[0042] During the transportation process, the transport device 100 may collide with other objects or produce shaking, etc. The protective plate 5 can prevent side collision from causing damage to the PCB board. When the transport device 100 moves in a narrow passage or is close to other equipment, the protective plate 5 can act as a barrier to avoid direct contact between the PCB board and the surrounding objects or the falling of the PCB board, thereby reducing the possibility of friction, collision and falling.

[0043] According to the transport device 100 of some embodiments of the present application, the moving part 1 is provided with a lifting track 12 extending in the height direction, and the carrying part 3 is formed with a sliding part 13 matched with the lifting track 12 to move on the lifting track 12.

[0044] The cooperation of the lifting track 12 and the sliding part 13 enables the carrying part 3 to move between different heights, shortens the time for adjusting the height, and improves the efficiency of the transportation operation. The wheels 11 of the moving part 1 enable the transport device 100 to move flexibly between different working areas. Combined with the height adjustment function of the lifting mechanism 2, the PCB board can be more accurately delivered to the designated position, improving the flexibility and efficiency of production.

[0045] According to the transport device 100 of some embodiments of the present application, the sliding part 13 comprises a first limiting plate 131, a second limiting plate 132 and a rolling part 133. The first limiting plate 131 and the second limiting plate 132 are arranged on the carrying part 3 in a spaced manner, and a receiving groove for receiving the lifting track 12 is formed between the first limiting plate 131 and the second limiting plate 132. The rolling part 133 is connected between the first limiting plate 131 and the second limiting plate 132, and the rolling part 133 is provided with a rolling piece in contact with the lifting track 12 and rotatable.

[0046] The first limiting plate 131 and the second limiting plate 132 are arranged on the carrying part 3 in a spaced manner, and a receiving groove for receiving the lifting track 12 is formed between the first limiting plate 131 and the second limiting plate 132, for positioning and limiting the lifting track 12, to ensure that the carrying part 3 does not deviate from the lifting track 12 during lifting, maintaining the stability and accuracy of movement. The rolling part 133 is connected between the first limiting plate 131 and the second limiting plate 132, and the rolling part 133 is provided with a rolling piece in contact with the lifting track 12 and rotatable. The rolling part 133 reduces the friction between the carrying part 3 and the lifting track 12, and the rolling piece rolls on the lifting track 12, making the lifting of the carrying part 3 more smooth and easy. Compared with sliding friction, the resistance of rolling friction is smaller, reducing energy loss and improving the efficiency of the transport device 100.

[0047] According to the transport device 100 of some embodiments of the present application, the lifting track 12 and the sliding part 13 are configured in one-to-one correspondence. The transport device 100 further comprises a handle 6 connected with the plurality of lifting tracks 12.

[0048] The handle 6 is connected to multiple lifting rails 12, providing a convenient operating area for the operator. By holding the handle 6, the operator can more easily control the lifting and movement of the transfer device 100. The design of the handle 6 makes the operation more humane, reduces the labor intensity of the operator, and improves work efficiency. The presence of the handle 6 can increase the operator's control over the transfer device 100 and improve the safety of the operation. During the transfer process, the operator can stably control the transfer device 100 through the handle 6 to avoid damage to personnel and PCB boards due to loss of control of the device due to unexpected situations.

[0049] According to the transfer device 100 of some embodiments of the present application, the lifting mechanism 2 includes: a cylinder body 22, which is arranged on the moving part 1; a piston rod 23, at least a portion of the piston rod 23 is accommodated in the cylinder body 22 and can be selectively moved relative to the cylinder body 22, and the end of the piston rod 23 is connected to the load-bearing part 3; an oil raising pedal 24 and an oil lowering pedal 25, which are respectively connected to the cylinder body 22 and are used to control the oil pressure in the cylinder body 22.

[0050] Cylinder body 22 is mounted on movable portion 1, providing a stable foundation for lifting operations. A piston rod 23 is at least partially housed within cylinder body 22 and is movable relative thereto, enabling the piston rod 23 to telescope within cylinder body 22, thereby raising and lowering load-bearing portion 3. When the piston rod 23 partially extends from cylinder body 22, load-bearing portion 3 rises; when the piston rod 23 partially retracts from cylinder body 22, load-bearing portion 3 descends. The structural relationship between piston rod 23 and cylinder body is simple and reliable, capable of withstanding heavy loads and suitable for transporting heavy items such as PCBs. Furthermore, an oil raising pedal 24 and an oil lowering pedal 25 are respectively connected to cylinder body 22 and are used to control the oil pressure within cylinder body 22. Pressing the oil raising pedal 24 increases the oil pressure within cylinder body 22, extending the piston rod 23 and raising load-bearing portion 3. Pressing the oil lowering pedal 25 decreases the oil pressure within cylinder body 22, retracting the piston rod 23 and lowering load-bearing portion 3.

[0051] According to the transfer device 100 of some embodiments of the present application, a buffer member 14 is formed on the moving part 1 , and the buffer member 14 protrudes from the upper side of the moving part 1 and extends in the travel direction of the moving part 1 .

[0052] As the transfer device 100 approaches the unloading platform, it generates a certain amount of impact force due to factors such as inertia. When the transfer device 100 is in place, the buffer member 14 can abut against the bottom of the unloading platform, absorbing and buffering this impact force. The smaller impact force can reduce the relative vibration between the transfer device 100 and the unloading platform, thereby reducing the degree of shaking of the PCB board on the supporting portion 3. When the transfer device 100 moves quickly to the unloading platform, the buffer member 14 can prevent the vibration caused by the transfer device 100 stopping due to contact with the unloading platform, protecting the PCB board from vibration.
