A semi-automatic frame-inserting type board receiving and releasing device

Abstract

This invention discloses a semi-automatic insert-frame type plate loading and unloading device, including a frame, a placement frame, and an opening and clamping mechanism. A first guide rail is provided on the frame along a first direction. The opening and clamping mechanism can move along the first guide rail along the first direction, enabling it to move accurately and quickly to a predetermined position, thus completing multiple movement operations in a short time. When the opening and clamping mechanism moves to a specific position along the first guide rail along the first direction, the opening cylinder drives the opening part to clamp one end of the clamping part, so that the other end of the clamping part is in an open state to realize the plate loading or unloading operation. This realizes the semi-automatic manual loading or unloading operation of plates into or out of the placement frame, solving the problem of difficulty in manually opening the placement frame to load or unload plates, reducing labor costs, improving work efficiency, and ensuring the safety of plate loading and unloading operations.

Description

Technical Field

[0001] This invention relates to the field of PCB manufacturing technology, and more specifically, to a semi-automatic frame-type board take-up and take-up device. Background Technology

[0002] PCB (Printed Circuit Board), also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board. A frame-type PCB loading and unloading machine is an automated device specifically designed to vertically insert PCBs (printed circuit boards) into a basket. This equipment plays a crucial role in the electronics manufacturing industry, helping to improve production efficiency and quality.

[0003] In traditional production processes, the handling and storage of PCB boards typically require a significant amount of manual labor. Baskets, as a common transportation tool, are used to carry and transport PCB boards. However, the number and structural design of the basket clamps directly impact operational efficiency and safety. Currently, many basket-type PCB loading and unloading machines rely on manual clamping and unloading. This method requires 2-3 operators to manually open the clamps on the basket before the PCB board can be retrieved or unloaded. This method is not only cumbersome but also poses safety hazards and is extremely inefficient.

[0004] Furthermore, the excessive weight of the basketball hoops also presents challenges for handling and transportation. Because the hoops contain a large number of PCB boards, their overall weight can be substantial. This not only increases the workload for operators but may also lead to safety issues during transport. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a semi-automatic insert-frame type board loading and unloading device. The device enables semi-automatic manual loading and unloading of boards into or from the placement frame, solving the problem of difficulty in manually opening the placement frame and unloading boards, reducing labor costs, improving work efficiency, and ensuring the safety of board loading and unloading operations.

[0006] The technical solution of the present invention is as follows: A semi-automatic insert-frame type board loading and unloading device includes a frame, a placement frame, and an opening and clamping mechanism. The frame is provided with a receiving cavity and a first guide rail arranged along a first direction. The placement frame is disposed in the receiving cavity and is provided with a clamping part for clamping the PCB board. The opening and clamping mechanism is disposed in the frame and can move along the first guide rail along the first direction. The opening and clamping mechanism includes an opening and clamping cylinder and an opening part driven by the opening and clamping cylinder. When the opening and clamping mechanism moves to a predetermined position along the first direction, the opening and clamping cylinder drives the opening part to clamp one end of the clamping part, so that the other end of the clamping part is in an open state to realize the board loading or unloading operation.

[0007] Furthermore, it also includes multiple positioning mechanisms, each of which includes a servo motor and an abutment portion fixedly connected to the output end of the servo motor. The abutment portion has a notch with an opening facing the receiving cavity at one end away from the servo motor. When the placement frame is placed in the receiving cavity, the servo motor drives the abutment portion to approach the placement frame so that the notch abuts against the corner of the placement frame.

[0008] Furthermore, there are eight positioning mechanisms. Four of the positioning mechanisms are located on the upper layer of the accommodating cavity and distributed at the four corners of the accommodating cavity, while the other four positioning mechanisms are distributed on the lower layer of the accommodating cavity and distributed at the four corners of the accommodating cavity.

[0009] Furthermore, the frame is provided with a lifting mechanism and a first fixing mechanism for fixing the placement frame. The lifting mechanism includes a drive motor and a second guide rail arranged along a second direction. The first fixing mechanism and the second guide rail are movably connected, and the first fixing mechanism can move along the second guide rail in a second direction. The first direction and the second direction are perpendicular to each other, and the second direction is a vertical direction.

[0010] Further, the first fixing mechanism includes a support base, a first limiting part, and a second limiting part. Two first limiting parts are provided, located on one side of the support base, and the second limiting part is located on the other side of the support base. The support base is provided with a mounting seat, a fixed shaft mounted within the mounting seat, and a first driving member fixedly connected to the mounting seat. The second limiting part includes a movable body and a base connected to one end of the movable body. The other end of the movable body is connected to the output end of the first driving member. At least a portion of the movable body extends outward and protrudes to form a protrusion. The protrusion has a mounting hole penetrating the thickness of the protrusion. At least a portion of the fixed shaft is located within the mounting hole. When the output end of the first driving member moves outward, the movable body rotates counterclockwise around the fixed shaft, causing the base to press against the side wall of the placement frame to limit the placement frame. When the output end of the first driving member moves inward, the movable body rotates clockwise around the fixed shaft, causing the base to move away from the placement frame to release the limitation on the placement frame.

[0011] Furthermore, it also includes a moving component, which includes a fixed frame, a moving wheel disposed at the bottom of the fixed frame, and a plurality of support shafts disposed within the fixed frame. The plurality of support shafts are arranged sequentially along the horizontal direction and have gaps. A manual knob and a baffle are disposed below the plurality of support shafts. The baffle has a first state and a second state. The baffle can be switched between the first state and the second state by the manual knob. When the baffle is in the first state, the baffle passes through the gap and protrudes upward to restrict the movement of the placement frame in the horizontal direction. When the baffle is in the second state, the top of the baffle is located within the gap or below the horizontal height of the gap to release the restriction on the placement frame.

[0012] Furthermore, the outer wall of the frame is provided with two guide portions and a second fixing mechanism located between the two guide portions. Each guide portion includes a limiting post, a guide seat, and multiple guide wheels installed in the guide seat. There is a gap between the limiting post and the guide seat to allow the fixing frame to pass through. The second fixing mechanism includes a fixing seat, a second driving member, and an abutment. A shaft is mounted inside the fixing seat. The abutment is provided with a protrusion. The protrusion is provided with a through hole that penetrates the thickness of the protrusion. The shaft passes through the through hole to movably mount the abutment on the fixing seat. One end of the abutment is connected to the output end of the second driving member. When the output end of the second driving member moves outward, the abutment rotates counterclockwise around the shaft so that the other end of the abutment presses against the fixing frame. When the output end of the second driving member moves inward, the abutment rotates clockwise around the shaft so that the other end of the abutment moves away from the fixing frame to release the limiting effect on the fixing frame.

[0013] Furthermore, the clamping mechanism is equipped with a sensor for detecting whether the clamping part has been successfully opened or closed. The clamping part includes multiple first clamping members, multiple second clamping members, and multiple third clamping members. The multiple first clamping members are arranged in a straight line along the width direction of the placement frame, and the first clamping members are used to clamp the upper edge of the PCB board. Multiple second clamping members are provided, and the multiple second clamping members are arranged in a straight line along the width direction of the placement frame, and the second clamping members are used to clamp the middle edge of the PCB board. The multiple third clamping members are arranged in a straight line along the width direction of the placement frame, and the third clamping members are used to clamp the lower edge of the PCB board.

[0014] Furthermore, the placement frame includes four uprights and two support plates. The lower ends of two adjacent uprights are connected by a horizontal column. Both support plates are arranged along the width direction of the placement frame, and both ends of the support plates are fixedly connected to the two horizontal columns respectively. The support plates are provided with multiple notches for snapping onto the PCB board.

[0015] Furthermore, the frame is equipped with operation buttons and an operation panel, and the operation buttons and the operation panel are electrically connected.

[0016] According to the above-described solution, the beneficial effects of this invention are as follows:

[0017] (1) The present invention provides a semi-automatic insert-frame type plate loading and unloading device, including a frame, a placement frame and an opening clamping mechanism. A first guide rail is provided on the frame along a first direction. The opening clamping mechanism can move along the first guide rail along the first direction, so that the opening clamping mechanism can move to a predetermined position accurately and quickly, thereby completing multiple movement operations in a short time. When the opening clamping mechanism moves to a specific position along the first guide rail along the first direction, the opening clamping cylinder drives the opening part to clamp one end of the clamping part, so that the other end of the clamping part is in an open state to realize the plate loading or unloading operation. This realizes the semi-automatic manual loading or unloading operation of plates into or out of the placement frame, solves the problem of difficulty in manually opening the placement frame to load or unload plates, reduces labor costs, improves work efficiency, and ensures the safety of loading and unloading operation.

[0018] (2) The present invention provides a semi-automatic insert frame type board taking and releasing device. Both ends of the PCB board are fixed in the placement frame by clamping parts. Correspondingly, there are two clamping mechanisms. The two clamping mechanisms are electrically connected to two operation buttons through a line. When the operator presses the two operation buttons at the same time, the clamping part of the clamping mechanism clamps one end of the clamping part, thereby opening the other end of the clamping part to release the PCB board. This design adopts a step-by-step operation mode, which improves the safety of the equipment.

[0019] (3) The present invention provides a semi-automatic frame-type board loading and unloading device. Each positioning mechanism includes a servo motor and an abutment part fixedly connected to the output end of the servo motor. The abutment part is provided with a notch. After the placement frame is placed in the accommodating cavity, the servo motor can drive the abutment part to approach the corner of the placement frame so that the notch of the abutment part abuts against the placement frame. This can prevent the placement frame from moving accidentally in the accommodating cavity and ensure that the placement frame is fixed in the accommodating cavity. During the board loading or unloading operation, the risk of PCB board damage can be reduced. Secondly, since the abutment part fixes the placement frame from four directions, the placement frame is prevented from shaking during the board loading or unloading operation, thereby increasing the stability of the equipment operation and reducing the possibility of failure and incorrect operation. Moreover, the abutment part is provided with a notch with an opening facing the accommodating cavity. The notch of the abutment part abuts against the corner of the placement frame. Compared with the conventional design, this can avoid the risk of the abutment part occupying the space inside the placement frame and thus easily causing the abutment part to hit the PCB board.

[0032] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention by way of example, but should not be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0033] In the description of this invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," etc., indicating orientation or positional relationships are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] To better understand the present invention, it will be further described below with reference to the accompanying drawings and embodiments:

[0036] See Figure 1 As shown, this embodiment of the invention provides a semi-automatic insert-type tray loading and unloading device, including a frame 1, a placement frame 3 and a moving component 9. The moving component 9 is used to transport the placement frame 3 to the side of the frame 1, and then manually push it onto the lifting mechanism 7 set in the frame 1. Then the lifting mechanism 7 drives the placement frame 3 to move down so that the placement frame 3 is placed into the placement cavity of the frame 1.

[0037] See Figures 2 to 4 As shown, the semi-automatic insert-type plate feeding and receiving device provided in this embodiment of the invention has an opening clamping mechanism 5 in the frame 1. The opening clamping mechanism 5 includes an opening clamping cylinder 51 and an opening clamping part 52 driven by the opening clamping cylinder 51. When the opening clamping mechanism 5 moves to a predetermined position along the first direction, the opening clamping cylinder 51 drives the opening clamping part 52 to clamp one end of the clamping part 4, so that the other end of the clamping part 4 is in an open state to realize the plate feeding or plate taking operation.

[0038] It should be noted that in this embodiment, the first direction is the width direction of the frame 1.

[0039] Specifically, the frame 1 is provided with a receiving cavity, the placement frame 3 is provided with a clamping part 4 for clamping the PCB board, the frame 1 is provided with a first guide rail 2 arranged along a first direction, and the clamping mechanism 5 can move along the first guide rail 2 along the first direction, so that the clamping mechanism 5 can move accurately and quickly to a predetermined position, thereby completing multiple movement operations in a short time. When the clamping mechanism 5 moves to a specific position along the first guide rail 2 along the first direction, the clamping cylinder 51 drives the clamping part 52 to clamp one end of the clamping part 4, so that the other end of the clamping part 4 is in an open state to realize the board placement or board removal operation, thereby realizing the semi-automatic manual placement or removal operation of boards into or from the placement frame 3, solving the problem of difficulty in manually opening the placement frame 3 to remove boards, reducing labor costs, improving work efficiency, and ensuring the safety of board removal and placement operations.

[0040] See Figures 4 to 5 As shown, in this embodiment, the semi-automatic frame-type board taking and placing device also includes multiple positioning mechanisms 6. Each positioning mechanism 6 includes a servo motor 61 and an abutment part 62 fixedly connected to the output end of the servo motor 61. The end of the abutment part 62 away from the servo motor 61 is provided with a notch with an opening facing the receiving cavity. When the placement frame 3 carrying the PCB board is placed in the receiving cavity, the servo motor 61 can drive the abutment part 62 to approach the corner of the placement frame 3 so that the notch of the abutment part 62 abuts against the placement frame 3, thereby preventing the placement frame 3 from moving accidentally in the receiving cavity and ensuring that the placement frame 3 is fixed in the receiving cavity. During the board taking or placing operation, the risk of damage to the PCB board can be reduced.

[0041] More specifically, see Figure 5 As shown, there are eight positioning mechanisms 6. Four positioning mechanisms 6 are located on the upper layer of the receiving cavity and distributed at the four corners of the receiving cavity, and the other four positioning mechanisms 6 are distributed on the lower layer of the receiving cavity and distributed at the four corners of the receiving cavity. That is, the four abutting parts 62 on the upper layer of the receiving cavity and the four abutting parts 62 on the lower layer of the receiving cavity fix the placement frame 3 from four directions. During board placement or board removal operations, the placement frame 3 is prevented from shaking, thereby increasing the stability of the equipment operation and reducing the possibility of malfunctions and erroneous operations. Moreover, the abutting parts 62 are provided with notches with openings facing the receiving cavity. The notches of the abutting parts 62 abut against the corners of the placement frame 3. Compared with conventional designs, this avoids the risk of the abutting parts 62 occupying the space inside the placement frame 3 and thus easily hitting the PCB board.

[0042] See Figures 5 to 7As shown, the frame 1 in this embodiment is equipped with a lifting mechanism 7 and a first fixing mechanism 8 for fixing the placement frame 3. The lifting mechanism 7 includes a drive motor 71 and a second guide rail 72 arranged along a second direction. The first fixing mechanism 8 and the second guide rail 72 are movably connected, and the first fixing mechanism 8 can move along the second guide rail 72 in the second direction. The first direction and the second direction are perpendicular to each other, and the second direction is the vertical direction, that is, the height direction of the frame 1. More specifically, when the placement frame 3 is transported to the side of the frame 1 by the moving component 9, the drive motor 71 drives the first fixing mechanism 8 to climb upward along the second guide rail 72, so that the first fixing mechanism 8 rises from the bottom of the receiving cavity to the top of the receiving cavity. Then the operator pushes the placement frame 3 onto the first fixing mechanism 8. Under the driving action of the drive motor 71, the first fixing mechanism 8 carries the placement frame 3 downward, so that the placement frame 3 is placed into the receiving cavity of the frame 1, thereby facilitating subsequent opening and placing or removing of the plate.

[0043] See Figures 6 to 7 As shown, the first fixing mechanism 8 includes a support base 81, a first limiting part 82, and a second limiting part 83. There are two first limiting parts 82, located on one side of the support base 81, and the second limiting part 83 is located on the other side of the support base 81. The support base 81 is provided with a mounting base 84, a fixed shaft 85 mounted in the mounting base 84, and a first driving member 86 fixedly connected to the mounting base 84. The fixed shaft 85 provides a rotation center for the second limiting part 83, so that the second limiting part 83 can rotate around the fixed shaft 85. At the same time, the fixed shaft 85 also restricts the left and right movement of the second limiting part 83, thereby ensuring that the second limiting part 83 is tightly fastened to the frame edge of the placement frame 3 after rotation.

[0044] More specifically, the second limiting part 83 includes a movable body 831 and a base 832 connected to one end of the movable body 831. The other end of the movable body 831 is connected to the output end of the first driving member 86. At least a portion of the movable body 831 extends outward to form a protrusion 8311. The protrusion 8311 is provided with a mounting hole penetrating the thickness of the protrusion 8311. At least a portion of the fixed shaft 85 is located in the mounting hole. The fixed shaft 85 and the mounting hole are clearance-fitted to ensure that the movable body 831 can... The movable body can rotate freely around the fixed axis 85. When the output end of the first driving member 86 moves outward, since the protrusion 8311 and the movable body 831 are an integral structure, the movable body rotates counterclockwise around the fixed axis 85 and drives the base 832 to press against the side wall of the placement frame 3 to limit the placement frame 3. When the output end of the first driving member 86 moves inward, the movable body rotates clockwise around the fixed axis 85 and drives the base 832 away from the placement frame 3 to release the limit on the placement frame 3.

[0045] See Figure 8As shown, in this embodiment, the semi-automatic insert-type tray delivery and take-up device further includes a moving component 9. The moving component 9 includes a fixed frame 91, a moving wheel 92 disposed at the bottom of the fixed frame 91, and a plurality of support shafts 93 disposed within the fixed frame 91. The fixed frame 91 moves horizontally via the moving wheel 92. The plurality of support shafts 93 are arranged sequentially along the horizontal direction with gaps. A manual knob 94 and a baffle 95 are disposed below the plurality of support shafts 93. In this embodiment, the manual knob 94 is a device for the operator to control the action of the baffle 95. By rotating the manual knob 94, the baffle 95 can be extended to block the sliding of the placement frame 3 or retracted to facilitate pushing the placement frame 3 out of the moving component 9.

[0046] More specifically, the baffle 95 has a first state and a second state. The first state is the extended state of the baffle 95, and the second state is the retracted state of the baffle 95. The baffle 95 can be switched between the first state and the second state by a manual knob. When the baffle 95 is in the first state, the baffle 95 passes through the gap and protrudes upward to restrict the movement of the placement frame 3 in the horizontal direction. When the baffle 95 is in the second state, the top of the baffle 95 is located within the gap or below the horizontal height of the gap to release the restriction on the placement frame 3.

[0047] See Figure 2 and Figure 3 As shown, the outer wall of the frame 1 is provided with two guide portions 10 and a second fixing mechanism 11 located between the two guide portions 10. Each guide portion 10 includes a limiting post 101, a guide seat 102, and a plurality of guide wheels 103 installed in the guide seat 102. There is a gap between the limiting post 101 and the guide seat 102 to allow the fixing frame 91 to pass through. The second fixing mechanism 11 includes a fixing seat 111, a second driving member 112, and an abutment member 113. A shaft 114 is mounted inside the fixing seat 111. A protrusion 1131 is provided on the abutment member 113. The protrusion 1131 is provided with a through-hole. A through hole with a thickness of 1131 is provided. The shaft 114 passes through the through hole to movably mount the abutment 113 on the fixed base 111. One end of the abutment 113 is connected to the output end of the second drive member 112. When the output end of the second drive member 112 moves outward, the abutment 113 rotates counterclockwise around the shaft 114 so that the other end of the abutment 113 presses against the fixed frame 91. When the output end of the second drive member 112 moves inward, the abutment 113 rotates clockwise around the shaft 114 so that the other end of the abutment 113 moves away from the fixed frame 91 to release the limiting effect on the fixed frame 91.

[0048] See Figure 9As shown, the clamping mechanism is equipped with a sensor to detect whether the clamping part has been successfully opened or closed. The clamping part 4 includes multiple first clamping members 41, multiple second clamping members 42, and multiple third clamping members 43. The multiple first clamping members 41 are arranged in a straight line along the width direction of the placement frame 3. The first clamping members 41 are used to clamp the upper edge of the PCB board. Multiple second clamping members 42 are arranged in a straight line along the width direction of the placement frame 3. The second clamping members 42 are used to clamp the middle edge of the PCB board. The multiple third clamping members 43 are arranged in a straight line along the width direction of the placement frame 3. The third clamping members 43 are used to clamp the lower edge of the PCB board.

[0049] See Figure 9 As shown, the placement frame 3 includes four uprights 31 and two support plates 32. The lower ends of two adjacent uprights 31 are connected by a horizontal column 33. The two support plates 32 are arranged along the width direction of the placement frame 3, and the two ends of the support plates 32 are fixedly connected to the two horizontal columns 33 respectively. The support plates 32 are provided with multiple notches for snapping onto the PCB board.

[0050] See Figure 1 and Figure 2 As shown, the frame 1 is equipped with an operation button 12 and an operation panel 13, which are electrically connected.

[0051] To further illustrate, this embodiment also provides a semi-automatic insert-frame type plate feeding and unloading device, specifically the plate feeding and unloading operations, as follows:

[0052] I. Placing the plate

[0053] The operator places the unloaded placement frame 3 onto the moving assembly 9, then pushes the moving assembly 9 so that the fixing frame 91 of the moving assembly 9, guided by the two guide parts 10, engages with the second fixing mechanism 11 located on the side wall of the frame 1, ensuring that the moving assembly 9 is fixed to the side of the frame 1. The operator walks to the side facing the operation panel 13 and simultaneously presses and holds the operation button 12 until the lifting mechanism 7 raises the first fixing mechanism 8 to the predetermined position, then releases the operation button 12. The operator then rotates the manual knob 94 on the moving assembly 9 to retract the baffle 95. The operator pushes the unloaded placement frame 3 onto the first fixing mechanism 8, and then simultaneously presses both operation buttons 12. The lifting mechanism 7 lowers the first fixing mechanism 8 to the bottom of the receiving cavity, allowing the placement frame 3 to be placed into the receiving cavity. Then, multiple positioning mechanisms 6 abut against the corners of the placement frame 3 to fix the placement frame 3 in place. After the clamping mechanism 5 moves along the first guide rail 2 to a predetermined position in the first direction, it opens the clamping part 4 of the first row. The operator puts the PCB board into the clamping part 4 of the first row. Then, the clamping mechanism 5 releases the clamping part 4 of the first row, and the clamping part 4 of the first row clamps the PCB board tightly. This process continues until the nth PCB board is put into the placement frame 3. When the placement frame 3 is full of PCB boards, the operator presses the operation button 12 at the same time. The lifting mechanism 7 drives the first fixing mechanism 8 to rise, so that the placement frame 3 placed on the first fixing mechanism 8 rises to the top of the receiving cavity. Then, the operation button 12 is released, and the manual knob 94 of the moving component 9 is rotated to make the baffle 95 retract. After the operator pushes the placement frame 3 into the moving component 9, the manual knob 94 is rotated again to make the baffle 95 extend to restrict the movement of the placement frame 3. Finally, the placement frame 3 is transported by the moving component 9, and the placement frame 3 loaded with PCB boards is transported to the designated position.

[0054] 2. Board removal operation

[0055] The operator pushes the movable component 9 next to the rack 1. A placement frame 3 carrying a PCB board is placed on the movable component 9. The fixing frame 91 of the movable component 9 is guided by two guide parts 10 and engages with the second fixing mechanism 11 located on the side wall of the rack 1 to ensure the movable component 9 is fixed next to the rack 1. The operator moves to the side facing the control panel 13 and simultaneously presses and holds the operation button 12 until the lifting mechanism 7, carrying the first fixing mechanism 8, rises to the predetermined position. Then, the operator releases the operation button 12. The operator then rotates the manual knob 94 on the movable component 9 to retract the baffle 95. The operator pushes the placement frame 3 carrying the PCB board onto the first fixing mechanism 8. Then, the operator simultaneously presses both operation buttons 12, and the lifting mechanism 7 lowers the first fixing mechanism 8 to the bottom of the receiving cavity, allowing the placement frame 3 to be placed into the receiving cavity. Multiple positioning mechanisms 6 then abut against the corners of the placement frame 3. The operator moves the first guide rail 2 to a predetermined position so that the placement frame 3 is fixed. The clamping mechanism 5 moves along the first guide rail 2 to a predetermined position in the first direction and opens the clamping part 4 of the first row. The operator takes the PCB board out of the clamping part 4 of the first row. Then the clamping mechanism 5 releases the clamping part 4 of the first row. This continues until the nth PCB board is taken out of the placement frame 3. When all the PCB boards in the placement frame 3 have been taken out, the operator presses the operation button 12 at the same time. The lifting mechanism 7 drives the first fixing mechanism 8 to rise so that the placement frame 3 placed on the first fixing mechanism 8 rises to the top of the receiving cavity. Then the operation button 12 is released and the manual knob 94 of the moving component 9 is rotated so that the baffle 95 retracts. After the operator pushes the placement frame 3 into the moving component 9, the manual knob 94 is rotated again so that the baffle 95 extends to restrict the movement of the placement frame 3. Finally, the placement frame 3 is transported by the moving component 9, and the empty placement frame 3 is transported to the designated position.
