[0046] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0047] As Figures 1 to 4 shown, a loading and unloading device provided by an embodiment of the present utility model includes a base 1, a first driving assembly 5, a second driving assembly 6, a plurality of material platforms 2, a plurality of first adjusting assemblies 3 and a plurality of second adjusting assemblies 4. The first driving assembly 5, the second driving assembly 6 and the material platform 2 are installed on the base 1. The first adjusting assembly 3 and the second adjusting assembly 4 are slidably connected to the base 1. The output end of the first driving assembly 5 is connected to the first adjusting assembly 3 and can drive the first adjusting assembly 3 to move relative to the base 1. The output end of the second driving assembly 6 is connected to the second adjusting assembly 4 and can drive the second adjusting assembly 4 to move relative to the base 1.

[0048] On each material table 2, a material plate area for placing material plates is formed by enclosing with a first adjusting component 3 and a second adjusting component 4, and the material plates in the material plate area can be loaded and unloaded. The first driving component 5 can drive a plurality of first adjusting components 3 to move in a first direction, and the second driving component 6 can drive a plurality of second adjusting components 4 to move in a second direction, so as to adjust the size of the material plate area on each material table 2, so that the material plate area can adapt to material plates of different models and sizes, and improve the usage range of the loading and unloading device. Wherein, the first direction a and the second direction b are perpendicular.

[0049] In this embodiment, the range of the material plate area in the first direction can be defined by the first adjusting component 3, and the range of the material plate area in the second direction can be defined by the second adjusting component 4, so that the material table 2 can adapt to the positioning of various material plates of different models and sizes. And driven by the first driving component 5, a plurality of first adjusting components 3 move together in the first direction, and driven by the second driving component 6, a plurality of second adjusting components 4 move together in the second direction, so that the material plate areas of a plurality of material tables 2 can be adjusted at one time, which can effectively reduce the adjustment time and improve the production efficiency.

[0050] Preferably, as Figure 1 shown, the number of material tables 2, the number of first adjusting components 3 and the number of second adjusting components 4 are the same, and the size of the material plate area on each material table 2 is adjusted by a set of first adjusting components 3 and second adjusting components 4.

[0051] In one embodiment, the material table 2 can be used as a loading material table or an unloading material table. Among a plurality of material tables 2, one of the material tables 2 is a loading material table, and the remaining material tables 2 are unloading material tables. For example, when detecting a PCB board, the material plates on the material plate area of the loading material table are detected one by one, and after the detection is completed, the qualified products, defective products, re-inspection products, etc. are placed on different unloading material tables respectively.

[0052] In one embodiment, as Figure 1 、 Figure 2 shown, the first adjusting component 3 includes a first adjusting member 31 and a second adjusting member 32 which are oppositely arranged. The first adjusting member 31 and the second adjusting member 32 are slidably connected to the base 1, and the first driving component 5 can drive each first adjusting member 31 and the corresponding second adjusting member 32 to approach or separate from each other in the first direction, so as to adjust the size of the material plate area in the first direction.

[0053] Among them, both the first adjusting member 31 and the second adjusting member 32 are connected to the output end of the first driving assembly 5. The first driving assembly 5 can drive a plurality of first adjusting members 31 and a plurality of second adjusting members 32 to move simultaneously, and the moving directions of the first adjusting member 31 and the second adjusting member 32 are opposite. On each material platform 2, when the first driving assembly 5 drives the first adjusting member 31 and the second adjusting member 32 to approach each other, the size of the material plate area in the first direction decreases; when the first driving assembly 5 drives the first adjusting member 31 and the second adjusting member 32 to move away from each other, the size of the material plate area in the first direction increases, which can adapt to material plates with different sizes in the first direction.

[0054] In an alternative embodiment, two first driving assemblies 5 can be provided, one of which is connected to the first adjusting member 31 and the other is connected to the second adjusting member 32. The first adjusting member 31 and the second adjusting member 32 move independently, and at least one of the first adjusting member 31 and the second adjusting member 32 is driven to move as needed, and the adjustment of the material plate area can also be achieved.

[0055] In one embodiment, a plurality of first linear guide rails 13 are provided on the base 1, and the first adjusting member 31 and the second adjusting member 32 are connected to the first linear guide rails 13, so that the first adjusting member 31 and the second adjusting member 32 can slide relative to the base 1.

[0056] In one embodiment, a first indicating member is provided on at least one of the plurality of first adjusting assemblies 3. The first indicating member is mounted on the first adjusting member 31 or the second adjusting member 32, and a first scale 14 is mounted on the base 1. When the first driving assembly 5 drives the first adjusting assembly 3 to move in the first direction, the moving distances of the first adjusting member 31 and the second adjusting member 32 can be read through the cooperation of the first indicating member and the first scale 14, so that the size of the material plate area in the first direction can be adjusted more precisely.

[0057] In one embodiment, as Figure 4 shown, the first adjusting assembly 3 further includes a first connecting rod 33 and a second connecting rod 34. The first adjusting member 31 is connected to the first connecting rod 33, and the second adjusting member 32 is connected to the second connecting rod 34. The first adjusting members 31 of the plurality of first adjusting assemblies 3 are arranged at intervals along the extending direction of the first connecting rod 33, and the second adjusting members 32 of the plurality of first adjusting assemblies 3 are arranged at intervals along the extending direction of the second connecting rod 34.

[0058] The first driving assembly 5 can drive the first connecting rod 33 and the second connecting rod 34 to move, so as to drive the first adjusting members 31 of the plurality of first adjusting assemblies 3 to move through the first connecting rod 33, and drive the second adjusting members 32 of the plurality of first adjusting assemblies 3 to move through the second connecting rod 34.

[0059] In this embodiment, all the first adjusting members 31 are connected by the first link 33, and all the second adjusting members 32 are connected by the second link 34. Under the drive of the first driving assembly 5, the multiple first adjusting assemblies 3 move together in the first direction, so that the material plate areas of the multiple material tables 2 can be adjusted at one time in the first direction, reducing the adjustment time of the loading and unloading device.

[0060] In one embodiment, as Figure 4 shown, the first link 33 and the second link 34 extend in the first direction and are parallel to each other. The multiple first adjusting members 31 are arranged at intervals in the first direction, the multiple second adjusting members 32 are arranged at intervals in the first direction, and the multiple first adjusting members 31 and the multiple second adjusting members 32 are arranged alternately.

[0061] One end of the first link 33 is connected to the output end of the first driving assembly 5, and one end of the second link 34 is connected to the output end of the first driving assembly 5. When the first driving assembly 5 drives the first link 33 to move in the first direction away from the first driving assembly 5, and the second link 34 moves in the first direction towards the first driving assembly 5, the first adjusting member 31 and the second adjusting member 32 move away from each other. When the first driving assembly 5 drives the first link 33 to move in the first direction towards the first driving assembly 5, and the second link 34 moves in the first direction away from the first driving assembly 5, the first adjusting member 31 and the second adjusting member 32 move closer to each other.

[0062] In one embodiment, as Figure 1 、 Figure 2 shown, the material table 2 is provided with a first guiding groove 21 and a second guiding groove 22, and the first guiding groove 21 and the second guiding groove 22 extend in the first direction. The end of the first adjusting member 31 away from the first link 33 is arranged in the first guiding groove 21, and the end of the second adjusting member 32 away from the second link 34 is arranged in the second guiding groove 22. Driven by the first driving assembly 5, the first adjusting member 31 can move along the first guiding groove 21, and the second adjusting member 32 can move along the second guiding groove 22, so as to change the positions of the first adjusting member 31 and the second adjusting member 32 relative to the material table 2, and further realize the adjustment of the material plate area in the first direction.

[0063] The first guiding groove 21 can avoid and guide the first adjusting member 31, and the second guiding groove 22 can avoid and guide the second adjusting member 32. The first adjusting member 31 and the second adjusting member 32 define the size of the material plate area in the first direction, and the material plate adapted to the material plate area can be stacked on the material table 2, facilitating the loading and unloading operation.

[0064] In one embodiment, as Figure 2 、 Figure 4As shown, the first adjustment component 3 further includes a first adapter 35 and a second adapter 36. The first adapter 35 is connected between the first link 33 and the first adjustment member 31, facilitating the connection between the first link 33 and the first adjustment member 31 through the first adapter 35. The second adapter 36 is connected between the second link 34 and the second adjustment member 32, facilitating the connection between the second link 34 and the second adjustment member 32 through the second adapter 36.

[0065] Wherein, the number of the first adapters 35 is the same as the number of the first adjustment members 31. The first link 33 can be connected to multiple first adjustment members 31 through multiple first adapters 35. The second link 34 can be connected to multiple second adjustment members 32 through multiple second adapters 36. Thus, when the first drive component 5 drives the first link 33 and the second link 34 to move, the first adjustment member 31 and the second adjustment member 32 can be driven to move.

[0066] In one embodiment, as Figure 2 、 Figure 4 shown, the base 1 is provided with a first avoidance hole 11 and a second avoidance hole 12. The first adjustment member 31 and the first link 33 are located on opposite sides of the base 1 in the third direction. The first adapter 35 passes through the first avoidance hole 11. The first avoidance hole 11 penetrates the base 1 along the third direction. The first adjustment member 31 is located above the base 1, and the first link 33 is located below the base 1. One end of the first adapter 35 is connected to the first adjustment member 31, and the other end of the first adapter 35 passes through the first avoidance hole 11 and is connected to the first link 33, enabling the connection between the first adjustment member 31 and the first link 33 located on opposite sides of the base 1.

[0067] The second adjustment member 32 and the second link 34 are located on opposite sides of the base 1 in the third direction. The second adapter 36 passes through the second avoidance hole 12. The second avoidance hole 12 penetrates the base 1 along the third direction. The second adjustment member 32 is located above the base 1, and the second link 34 is located below the base 1. One end of the second adapter 36 is connected to the second adjustment member 32, and the other end of the second adapter 36 passes through the second avoidance hole 12 and is connected to the second link 34, enabling the connection between the second adjustment member 32 and the second link 34 located on opposite sides of the base 1.

[0068] Wherein, the first direction a, the second direction b, and the third direction c are perpendicular to each other in pairs. In a rectangular coordinate system, the first direction a is the X direction, the second direction b is the Y direction, and the third direction c is the Z direction.

[0069] In one embodiment, the first adjusting member 31 and the second adjusting member 32 extend along a third direction. In the third direction, the material table 2 is disposed above the base 1, and the material table 2 is horizontally placed. One end of the first adjusting member 31 is connected to the first link 33 through a first adapter 35, and the other end of the first adjusting member 31 passes through the first guiding groove 21. One end of the second adjusting member 32 is connected to the second link 34 through a second adapter 36, and the other end of the second adjusting member 32 passes through the second guiding groove 22. After the positions of the first adjusting member 31 and the second adjusting member 32 are adjusted, the material plate is placed in the material plate area between the first adjusting member 31 and the second adjusting member 32.

[0070] In one embodiment, as Figure 3 , Figure 4 shown, the first driving assembly 5 includes a first driving member, a first transmission assembly 52, a second transmission assembly 53, and a connecting shaft 54. The first driving member is installed on the base 1. The first transmission assembly 52 and the second transmission assembly 53 are oppositely disposed. The connecting shaft 54 is installed on the base 1 and is located between the first transmission assembly 52 and the second transmission assembly 53. Among them, the first transmission assembly 52, the second transmission assembly 53, and the connecting shaft 54 are located below the base 1 in the third direction.

[0071] The output end of the first driving member is connected to the connecting shaft 54. The first transmission assembly 52 and the second transmission assembly 53 are drivingly connected through the connecting shaft 54. The first link 33 is connected to the first transmission assembly 52. The first driving member drives the first link 33 to move through the first transmission assembly 52, and then drives a plurality of first adjusting members 31 to move. The second link 34 is connected to the second transmission assembly 53. The first driving member drives the second link 34 to move through the second transmission assembly 53, and then drives a plurality of second adjusting members 32 to move.

[0072] When adjusting the distance between the first adjusting member 31 and the second adjusting member 32, the first driving member can drive the connecting shaft 54 to rotate, so as to drive the first transmission assembly 52 and the second transmission assembly 53 to perform transmission synchronously, and then make a plurality of first adjusting members 31 and a plurality of second adjusting members 32 move synchronously. On each material table 2, the first adjusting member 31 and the corresponding second adjusting member 32 can approach or move away from each other.

[0073] In one embodiment, as Figure 3 , Figure 4 shown, the first driving member is a first motor 51a or a first handwheel 51b, so that the first adjusting assembly 3 can be automatically adjusted or manually adjusted.

[0074] Specifically, when the first driving member is the first motor 51a, the first motor 51a is installed below the base 1. The output end of the first motor 51a can drive the connecting shaft 54 to rotate, thereby driving the first transmission assembly 52 and the second transmission assembly 53 to synchronously transmit power, so as to drive the first connecting rod 33 and the second connecting rod 34 to move.

[0075] Among them, the output end of the first motor 51a is connected to the connecting shaft 54 through the first motor transmission assembly 55.

[0076] When the first driving member is the first handwheel 51b, the first handwheel 51b is installed above the base 1. The first handwheel 51b is connected to the connecting shaft 54 through the handwheel transmission assembly 56. By rotating the first handwheel 51b, the connecting shaft 54 can be driven to rotate under the transmission of the handwheel transmission assembly 56, and then the first transmission assembly 52 and the second transmission assembly 53 are driven to synchronously transmit power.

[0077] The handwheel transmission assembly 56 includes a second driving pulley 561, a second driven pulley 562, and a second transmission belt 563. The second driving pulley 561 is coaxially connected to the first handwheel 51b, the second driven pulley 562 is installed on the connecting shaft 54, and the second transmission belt 563 is wound around the second driving pulley 561 and the second driven pulley 562. By rotating the first handwheel 51b, the second driving pulley 561 can be driven to rotate. Under the action of the second transmission belt 563, the second driven pulley 562 drives the connecting shaft 54 to rotate.

[0078] In an embodiment, as Figure 3 、 Figure 4 shown, the first transmission assembly 52 includes a first driving wheel 521, a first driven wheel 522, and a first synchronous belt 523. The second transmission assembly 53 includes a second driving wheel 531, a second driven wheel 532, and a second synchronous belt 533. The first driving wheel 521 and the second driving wheel 531 are arranged on the connecting shaft 54. The first driven wheel 522 and the second driven wheel 532 are installed below the base 1. The first synchronous belt 523 is wound around the first driving wheel 521 and the first driven wheel 522. The second synchronous belt 533 is wound around the second driving wheel 531 and the second driven wheel 532. The first connecting rod 33 is connected to the first synchronous belt 523, and the second connecting rod 34 is connected to the second synchronous belt 533.

[0079] The first driving member can drive the connecting shaft 54 to rotate, and then drive the first driving wheel 521 and the second driving wheel 531 to rotate synchronously. When the first synchronous belt 523 moves around the first driving wheel 521 and the first driven wheel 522, it can drive the first connecting rod 33 to reciprocate in the first direction. When the second synchronous belt 533 moves around the second driving wheel 531 and the second driven wheel 532, it can drive the second connecting rod 34 to reciprocate in the first direction, thereby realizing the mutual approach or separation of the first adjusting member 31 and the second adjusting member 32.

[0080] In one embodiment, as Figure 1 、 Figure 2 shown, the second adjusting assembly 4 includes a third adjusting member 41 and a fourth adjusting member 42 which are oppositely arranged. The second driving assembly 6 can drive each third adjusting member 41 and the corresponding fourth adjusting member 42 to approach each other in the second direction to adjust the size of the loading plate area in the second direction.

[0081] Both the third adjusting member 41 and the fourth adjusting member 42 are connected to the output end of the second driving assembly 6. The second driving assembly 6 can drive a plurality of third adjusting members 41 and a plurality of fourth adjusting members 42 to move simultaneously, and the moving directions of the third adjusting member 41 and the fourth adjusting member 42 are opposite. On each material table 2, when the second driving assembly 6 drives the third adjusting member 41 and the fourth adjusting member 42 to approach each other, the size of the loading plate area in the second direction decreases. When the second driving assembly 6 drives the third adjusting member 41 and the fourth adjusting member 42 to move away from each other, the size of the loading plate area in the second direction increases, which can adapt to loading plates with different sizes in the second direction.

[0082] In an alternative embodiment, two second driving assemblies 6 can be provided, one of which is connected to the third adjusting member 41 and the other is connected to the fourth adjusting member 42. The third adjusting member 41 and the fourth adjusting member 42 move independently, and at least one of the third adjusting member 41 and the fourth adjusting member 42 is driven to move as needed, and the adjustment of the loading plate area can also be realized.

[0083] As an example, as Figure 1 、 Figure 2 shown, the first adjusting assembly 3 includes a first adjusting member 31 and a second adjusting member 32. The first adjusting member 31 and the second adjusting member 32 are oppositely arranged in the first direction. The second adjusting assembly 4 includes a third adjusting member 41 and a fourth adjusting member 42. The third adjusting member 41 and the fourth adjusting member 42 are oppositely arranged in the second direction. On each material table 2, a loading plate area is enclosed by the first adjusting member 31, the second adjusting member 32, the third adjusting member 41 and the fourth adjusting member 42. During the loading and unloading process, the loading plate can enter or leave the loading plate area.

[0084] The first driving component 5 can drive a plurality of first adjusting members 31 and a plurality of second adjusting members 32 to move, and the second driving component 6 can drive a plurality of third adjusting members 41 and a plurality of fourth adjusting members 42 to move, so that on each material table 2, the first adjusting member 31 and the corresponding second adjusting member 32 can approach or move away from each other, and the third adjusting member 41 and the corresponding fourth adjusting member 42 can approach or move away from each other, thereby adjusting the size of the material plate area.

[0085] In one embodiment, as Figure 2 shown, the second adjusting component 4 further includes a third connecting rod 43 and a fourth connecting rod 44. The third adjusting member 41 is connected to the third connecting rod 43, and the fourth adjusting member 42 is connected to the fourth connecting rod 44. The third adjusting members 41 of the plurality of second adjusting components 4 are arranged at intervals along the extending direction of the first connecting rod 33, and the fourth adjusting members 42 of the plurality of second adjusting components 4 are arranged at intervals along the extending direction of the second connecting rod 34.

[0086] The third connecting rod 43 and the fourth connecting rod 44 are slidably connected to the base 1. The second driving component 6 can drive the third connecting rod 43 and the fourth connecting rod 44 to move, so that the third adjusting members 41 of the plurality of second adjusting components 4 can be driven to move through the third connecting rod 43, and the fourth adjusting members 42 of the plurality of second adjusting components 4 can be driven to move through the fourth connecting rod 44.

[0087] In this embodiment, all the third adjusting members 41 are connected by the third connecting rod 43, and all the fourth adjusting members 42 are connected by the fourth connecting rod 44, so that under the drive of the second driving component 6, a plurality of second adjustments can move together in the second direction, and further, the material plate areas of a plurality of material tables 2 can be adjusted at one time in the second direction, reducing the adjustment time of the loading and unloading device.

[0088] In one embodiment, as Figure 2 shown, the third connecting rod 43 and the fourth connecting rod 44 extend along the first direction and are parallel to each other. The plurality of third adjusting members 41 are arranged at intervals along the first direction, and the plurality of fourth adjusting members 42 are arranged at intervals along the first direction. One end of the third connecting rod 43 is connected to the output end of the second driving component 6, and one end of the fourth connecting rod 44 is connected to the output end of the second driving component 6. When the second driving component 6 drives the third connecting rod 43 to move in the second direction towards the material table 2 and the fourth connecting rod 44 moves in the second direction towards the material table 2, that is, when the third connecting rod 43 and the fourth connecting rod 44 move towards each other, the third adjusting member 41 and the fourth adjusting member 42 approach each other. When the second driving component 6 drives the third connecting rod 43 to move in the second direction away from the material table 2 and the second connecting rod 34 moves in the first direction away from the material table 2, that is, when the third connecting rod 43 and the fourth connecting rod 44 move away from each other, the third adjusting member 41 and the fourth adjusting member 42 move away from each other.

[0089] In one embodiment, as Figure 2 shown, at least one of the plurality of second adjusting components 4 is provided with a second indicating member 45. The second indicating member 45 is mounted on the third link 43 or the fourth link 44. A second scale 16 is mounted on the base 1. When the second driving component 6 drives the second adjusting component 4 to move in the second direction, through the cooperation of the second indicating member 45 and the second scale 16, the moving distances of the third link 43 and the fourth link 44 can be read, and then the moving distances of the third adjusting member 41 and the fourth adjusting member 42 can be obtained, so that the size of the feeding plate area in the second direction can be adjusted more precisely.

[0090] In one embodiment, a second linear guide 15 is provided on the base 1. The third link 43 and the fourth link 44 are connected to the second linear guide 15, so that the third link 43 and the fourth link 44 can slide relative to the base 1.

[0091] In one embodiment, as Figure 1 、 Figure 2 shown, a third guiding groove 23 and a fourth guiding groove 24 are provided on the material table 2. The third guiding groove 23 and the fourth guiding groove 24 extend in the second direction. One end of the third adjusting member 41 away from the third link 43 is arranged in the third guiding groove 23. The third guiding groove 23 can be used to avoid and guide the third adjusting member 41. One end of the fourth adjusting member 42 away from the fourth link 44 is arranged in the fourth guiding groove 24. The fourth guiding groove 24 can be used to avoid and guide the fourth adjusting member 42.

[0092] Driven by the second driving component 6, the third adjusting member 41 can move along the third guiding groove 23, and the fourth adjusting member 42 can move along the fourth guiding groove 24, so as to change the positions of the third adjusting member 41 and the fourth adjusting member 42 relative to the material table 2, and further realize the adjustment of the feeding plate area in the second direction.

[0093] In one embodiment, as Figure 1 、 Figure 2 shown, the second driving component 6 includes a second driving member and at least one third transmission component 62. The second driving member is mounted on the base 1, and the third transmission component 62 is mounted on the base 1 and is located above the base 1 in the third direction. The output end of the second driving member is connected to the third transmission component 62. The third transmission component 62 can drive the third link 43 and the fourth link 44 to approach or separate from each other in the second direction under the drive of the second driving member, and further drive a plurality of third adjusting members 41 and a plurality of fourth adjusting members 42 to move.

[0094] Among them, at least two third transmission components 62 are provided. The third link 43 and the fourth link 44 extend along the first direction. The two third transmission components 62 are respectively arranged at both ends of the base 1 in the first direction. The third link 43 and the fourth link 44 are both connected between the two third transmission components 62, which can ensure the smooth movement of the third link 43 and the fourth link 44. It can be understood that the two third transmission components 62 are connected by a transmission shaft 63, and the two third transmission components 62 move synchronously.

[0095] When the third link 43 and the fourth link 44 are discontinuous along the first direction and are provided with multiple segments, the number of the third transmission components 62 is correspondingly increased.

[0096] In an embodiment, as Figure 2 、 Figure 4 shown, the second driving member is the second motor 61a or the second handwheel 61b, so that the second adjusting component 4 can be automatically adjusted or manually adjusted.

[0097] Specifically, when the second driving member is the second motor 61a, the second motor 61a is installed below the base 1, and the output end of the second motor 61a is connected to the transmission shaft 63, thereby driving the two third transmission components 62 to drive synchronously. Through the third transmission components 62, the third link 43 and the fourth link 44 can be driven to move.

[0098] Among them, the output end of the second motor 61a is connected to the transmission shaft 63 through the second motor transmission component 64. The structure of the second motor transmission component 64 is the same as that of the first motor transmission component 55, and will not be described in detail here.

[0099] When the second driving member is the second handwheel 61b, the second handwheel 61b is arranged above the base 1, and the second handwheel 61b is installed on the connecting shaft 54. By rotating the second handwheel 61b, the transmission shaft 63 can be driven to rotate, thereby driving the two third transmission components 62 to drive synchronously.

[0100] In an embodiment, as Figure 2 shown, the third transmission component 62 includes a third driving wheel 621, a third driven wheel 622 and a third synchronous belt 623. The third driving wheel 621 is connected to the output end of the second driving member, the third driven wheel 622 is installed on the base 1, and the third synchronous belt 623 is wound around the third driving wheel 621 and the third driven wheel 622. The second driving member can drive the third driving wheel 621 to rotate, thereby driving the third synchronous belt 623 to transmit power.

[0101] The third synchronous belt 623 has a first section and a second section. The first section of the third synchronous belt is connected to the third connecting rod 43 and is located below the third driving pulley 621 and the third driven pulley 622. The second section of the third synchronous belt is connected to the fourth connecting rod 44 and is located above the third driving pulley 621 and the third driven pulley 622. The driving directions of the first section and the second section of the third synchronous belt are opposite. Thus, when the third synchronous belt 623 is driven by the second driving member to transmit power, the third connecting rod 43 and the fourth connecting rod 44 can move in opposite directions in the second direction, and the third connecting rod 43 and the fourth connecting rod 44 can approach or move away from each other.

[0102] In one embodiment, as Figure 1 , Figure 3 shown, the loading and unloading device further includes a plurality of lifting components 7. The lifting components 7 are installed on the base 1, and the output end of each lifting component 7 is connected to the corresponding material table 2 to drive the material table 2 to move up and down. During the loading and unloading process, the lifting components 7 drive the material table 2 to move, facilitating the material table 2 to receive or feed the material plate. By means of the lifting components 7, the up and down moving distance of the material table 2 can be controlled, so that the uppermost material plate in the material plate area is always kept on one plane, facilitating loading and unloading.

[0103] In one embodiment, the lifting component 7 includes a third driving member 71 and a rack. The third driving member 71 is a motor, and the output end of the motor is connected with a gear. The gear meshes with the rack. By driving the gear to rotate with the motor, the rack can be driven to reciprocate in the third direction, so that the material table 2 rises or falls.

[0104] In one embodiment, as Figure 1 shown, a first limit transmission device 17 and a second limit sensor 18 are arranged on the base 1. The first limit transmission device 17 is arranged above the second limit sensor 18. An induction piece 72 is installed at one end of the rack away from the material table 2. The induction piece 72 can cooperate with the first limit sensor to limit the highest position of the material table 2, and the induction piece 72 can cooperate with the second limit sensor 18 to limit the lowest position of the material table 2. When the third driving member 71 drives the rack to move, the induction piece 72 can move between the first limit transmission device 17 and the second limit sensor 18, and the movable range of the material table 2 is limited by the first limit transmission device 17 and the second limit sensor 18.

[0105] On the other hand, an embodiment of the present invention provides a PCB processing device, including the loading and unloading device of the above embodiment.

[0106] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
