Description

Technical Field

[0001] This application relates to the field of circuit board forming and processing technology, and in particular to a workbench and PCB processing equipment. Background Technology

[0002] PCB manufacturing is trending towards automation and intelligence, which in turn requires more intelligent PCB manufacturing equipment.

[0003] The PCB needs to undergo subtractive processing to make the shape of the PCB conform to the pre-designed shape; before subtractive processing, the PCB must be placed on the workbench for positioning.

[0004] In related technologies, the worktable includes a support platform and an ejector mechanism. The support platform is used to support and position the PCB, while the ejector mechanism is used to vertically eject the processed PCB from the support platform. Furthermore, the drive component in the ejector mechanism is placed horizontally to reduce the space occupied by the ejector mechanism in the vertical direction, thereby improving the stability of the worktable. However, existing ejector mechanisms have insufficiently smooth ejection action, are prone to interference, affecting the ejection function and consequently impacting production efficiency. Utility Model Content

[0005] Therefore, it is necessary to provide a workbench and PCB processing equipment that can ensure the smooth operation of the ejector action and improve production efficiency.

[0006] An embodiment of the first aspect of this application provides a workbench, including:

[0007] Support components;

[0008] A support plate, fixed to the support member, is used to support the workpiece; the support plate is provided with a first through hole.

[0009] The first material-lifting mechanism includes a material-lifting base and a first lifting component;

[0010] The top material base is located on the side of the material support plate near the support member, and the top material base is provided with an installation groove;

[0011] One end of the first lifting member is rotatably connected to the mounting groove, and the top material base can move in the second direction to push one end of the first lifting member along the mounting groove, so that the other end of the first lifting member can extend into and protrude from the first through hole to lift the workpiece.

[0012] In one embodiment, the first lifting mechanism further includes a first lifting drive member connected to the lifting base and extending along the second direction. The mounting groove is an inclined groove. The first lifting drive member can drive the lifting base to move along the second direction so that the first lifting member moves along the mounting groove, thereby enabling the first lifting member to pass through the first through hole and reach the first height.

[0013] In one embodiment, the first lifting drive includes:

[0014] A first driving member is disposed on the side of the material support plate near the support member. The first driving member is connected to the top material base and is used to drive the top material base to move along the second direction.

[0016] The movable component is connected to the top material base and is movably connected to the first guide component.

[0017] In one embodiment, the first guide member is provided with a through groove and a slot; the through groove passes through the first guide member along the second direction, and the top material base passes through the through groove; the slot is arranged parallel to the through groove and communicates with the through groove.

[0018] The movable component includes a first roller, which is rotatably connected to the top material base and rolls within the slot.

[0019] In one embodiment, the first lifting member includes a first lifting portion, a first connecting portion, and a rotating portion. The first connecting portion is rotatably connected to the mounting groove. The first lifting portion passes through the first through hole and is connected to the first connecting portion. The rotating portion is rotatably connected to the end of the first lifting portion away from the first connecting portion.

[0020] In one embodiment, the first connecting part includes a connecting shaft, which is rotatably connected to one end of the first lifting part away from the rotating part, and the two ends of the connecting shaft are rolled into the mounting groove.

[0021] In one embodiment, the first connecting part includes a connecting shaft and a second roller. The connecting shaft is connected to the end of the first lifting part away from the rotating part, and the second roller is connected to the connecting shaft and is rotatably connected in the mounting groove.

[0022] In one embodiment, the first lifting portion includes a first lifting sub-portion and a second lifting sub-portion, the first lifting sub-portion being connected to the first connecting portion; one end of the second lifting sub-portion is connected to the end of the first lifting sub-portion away from the first connecting portion, and the other end is connected to the rotating portion, and the second lifting sub-portion is capable of rotating relative to the first lifting sub-portion about a third direction, the third direction being perpendicular to the second direction.

[0023] In one embodiment, the mounting groove has a first contact surface and a second contact surface, both of which extend along a first direction, and the end of the first lifting member near the top material base is movable along the first contact surface and the second contact surface, wherein the first direction is not perpendicular to the second direction.

[0024] In one embodiment, the top material base is further provided with a guide groove on the side near the material support plate. The guide groove extends along the second direction and communicates with the mounting groove; the first lifting member passes through the guide groove.

[0025] In one embodiment, a positioning element is provided on the side of the material support plate away from the support member, the positioning element being used to position the workpiece; the positioning element has a second height along a third direction, the third direction being perpendicular to the second direction; the second height is less than the first height.

[0026] In one embodiment, the worktable further includes a second ejector mechanism, the second ejector mechanism comprising:

[0027] A top plate is provided on the side of the support plate near the support member; the top plate is provided with a second through hole corresponding to the first through hole; the top base is located on the side of the top plate away from the support plate and is movably connected to the top plate; the first lifting member passes through the second through hole; the first lifting drive member is provided on the side of the top plate away from the support plate.

[0028] The second lifting member is disposed on the side of the top plate near the support plate; the support plate is provided with a third through hole, and the second lifting member passes through the third through hole;

[0029] The second lifting drive is connected to the top plate and is used to drive the top plate to move along the third direction so that the second lifting member protrudes from the third through hole to lift the workpiece to a third height, the third height being less than the first height.

[0030] In one embodiment, the third height is smaller than the second height.

[0031] In one embodiment, a second guide is provided in the second through hole, and the first lifting member passes through the second guide. The second guide is used to guide the first lifting member to move in the third direction.

[0032] In one embodiment, the second lifting drive includes:

[0033] An expansion member is provided on the side of the top plate away from the support plate. The expansion member can expand or contract to drive the top plate to move in the third direction.

[0034] In one embodiment, a first gap exists between the top material base and the top material plate.

[0035] An embodiment of the second aspect of this application provides a PCB processing device, including a carrier component, a processing component, and a worktable as described in any of the above embodiments. The workpiece is a PCB. The worktable and the processing component are both connected to the carrier component. The processing component is used to process the PCB placed on the carrier plate.

[0036] The worktable provided in this application embodiment supports the workpiece via a support plate for processing. When processing is complete and the workpiece needs to be lifted, the lifting base moves along a second direction, while the first lifting member moves along a mounting groove. The other end of the first lifting member extends into and protrudes from a first through hole, thereby lifting the workpiece. Since one end of the first lifting member is rolled into the mounting groove, meaning there is rolling friction between the first lifting member and the mounting groove of the lifting base, the frictional resistance between them is reduced, improving the smoothness of the first lifting member's movement along the mounting groove. This ensures smooth operation of the lifting action of the first lifting member, smoothly lifting the workpiece, thereby improving workpiece processing efficiency and production efficiency. Furthermore, the mounting groove converts the movement of the lifting base along the second direction into movement of the first lifting member along the thickness direction of the support plate. This reduces the height of the first lifting mechanism, thereby lowering the overall height of the worktable, lowering the center of gravity of the worktable, and improving its stability.

[0056] PCB manufacturing is trending towards automation and intelligence, thus requiring more intelligent PCB processing equipment. Circuit boards need to undergo subtractive processing to ensure their shape conforms to a pre-designed form. Before subtractive processing, the circuit board must be positioned on a worktable.

[0057] In related technologies, the worktable includes a support platform and an ejector mechanism. The support platform is used to support and position the PCB, while the ejector mechanism is used to vertically eject the processed PCB from the support platform. Furthermore, the drive component in the ejector mechanism is placed horizontally to reduce the space occupied by the ejector mechanism in the vertical direction, thereby improving the stability of the worktable. However, existing ejector mechanisms have insufficiently smooth ejection action, are prone to interference, affecting the ejection function and consequently impacting production efficiency.

[0058] To address the aforementioned issues, this application provides a workbench and PCB processing equipment that ensures smooth operation of the ejector action and improves production efficiency.

[0059] Firstly, see Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, this application embodiment provides a workbench 10, including a support member 11, a material support plate 12, and a first lifting mechanism 13; the material support plate 12 is connected to the support member 11 and is used to support the workpiece 30; the material support plate 12 is provided with a first through hole 121, and the first lifting mechanism 13 includes a lifting base 131 and a first lifting member 132; the lifting base 131 is located on the side of the material support plate 12 near the support member 11 and can move along the second direction Y; the lifting base 131 is provided with a mounting groove 1311; the mounting groove 1311 extends along the first direction X, and the angle between the first direction X and the second direction Y is an acute angle; one end of the first lifting member 132 is rotatably connected to the mounting groove 1311, and when the first lifting member 132 moves along the mounting groove 1311, the other end of the first lifting member 132 can extend into and protrude from the first through hole 121 to lift the workpiece 30.

[0060] Specifically, the second direction Y can be parallel to the plane of the support plate 12, and the angle between the first direction X and the second direction Y is an acute angle. That is to say, the mounting groove 1311 is inclined relative to the support plate 12. In this way, when the first lifting member 132 moves along the mounting groove 1311, the first lifting member 132 can move along the thickness direction of the support plate 12, and the other end of the first lifting member 132 can extend into and protrude from the first through hole 121 to lift the workpiece 30. In other words, the mounting groove 1311 can convert the movement of the lifting base 131 along the second direction Y into the movement of the first lifting member 132 along the thickness direction of the support plate 12. In this way, the height of the first lifting mechanism 13 can be reduced, thereby reducing the height of the entire worktable 10, lowering the center of gravity of the worktable 10, and improving the stability of the worktable 10.

[0061] One end of the first lifting member 132 is tumbledly connected to the mounting groove 1311. That is, there is rolling friction between the first lifting member 132 and the mounting groove 1311 of the top material base 131. This reduces the frictional resistance between the first lifting member 132 and the mounting groove 1311 of the top material base 131, improves the smoothness of the first lifting member 132 moving along the mounting groove 1311, and ensures the smooth operation of the first lifting member 132 in lifting the workpiece 30, thereby improving the processing efficiency of the workpiece 30 and thus improving production efficiency.

[0062] In summary, the workbench 10 provided in this embodiment of the application supports the workpiece 30 via the support plate 12 when it needs to be processed. When the processing of the workpiece 30 is completed and it needs to be lifted, the lifting base 131 moves along the second direction Y, and the first lifting member 132 moves along the mounting groove 1311. The other end of the first lifting member 132 extends into and protrudes from the first through hole 121, thereby lifting the workpiece 30. Since one end of the first lifting member 132 is rolledly connected to the mounting groove 1311, meaning there is rolling friction between the first lifting member 132 and the mounting groove 1311 of the ejector base 131, the frictional resistance between the first lifting member 132 and the mounting groove 1311 of the ejector base 131 is reduced, improving the smoothness of the first lifting member 132's movement along the mounting groove 1311. This ensures the smooth operation of the ejector action of the first lifting member 132, smoothly lifting the workpiece 30, thereby improving the processing efficiency of the workpiece 30 and thus increasing production efficiency. Furthermore, the mounting groove 1311 can convert the movement of the ejector base 131 along the second direction Y into the movement of the first lifting member 132 along the thickness direction of the support plate 12. This reduces the height of the first ejector mechanism 13, thereby lowering the overall height of the worktable 10, lowering the center of gravity of the worktable 10, and improving the stability of the worktable 10.

[0063] For example, the workbench 10 may include a plurality of first lifting mechanisms 13. For instance, the workbench 10 may include two first lifting mechanisms 13 arranged in parallel. A plurality of mounting slots 1311 may be provided at intervals on the lifting base 131. The number of first lifting members 132 may be multiple, and the multiple first lifting members 132 correspond one-to-one with the multiple mounting slots 1311. A plurality of first through holes 121 corresponding one-to-one with the multiple first lifting members 132 may be provided on the support plate 12. In this way, it can be ensured that the workpiece 30 is in a parallel state with the support plate 12 when it is stably lifted or lowered, that is, the workpiece 30 is in a horizontal state.

[0064] For example, the workpiece 30 can be a printed circuit board (PCB). In this embodiment, one PCB or multiple PCBs can be mounted. Multiple PCBs can be stacked. A pad can be provided on the side of the PCB near the support plate 12 to protect the PCB.

[0065] Understandably, the worktable 10 can be mounted on the support assembly 20, and there can be one or more support members 11. The worktable 10 can be mounted on the support assembly 20 through the support members 11, so that an installation space can be left between the support assembly 20 and the material support plate 12 for the installation of the first material lifting mechanism 13.

[0066] The first height can be understood as the distance between the workpiece 30 and the support plate 12 when the workpiece 30 is lifted by the first lifting member 132, that is, the end of the first lifting member 132 away from the top material base 131 protrudes from the side of the support plate 12 away from the top material base 131, and the distance between the end of the first lifting member 132 away from the top material base 131 and the support plate 12.

[0067] In one embodiment, see [reference] Figure 7 As shown, the first material feeding mechanism 13 also includes a first lifting drive member 133. The first lifting drive member 133 is connected to the material feeding base 131 and extends along the second direction Y. The first lifting drive member 133 can drive the material feeding base 131 to move along the second direction Y, so that the first lifting member 132 moves along the mounting groove 1311, thereby enabling the first lifting member 132 to pass through the first through hole 121 and reach the first height.

[0068] Therefore, when the workpiece 30 is completed and needs to be lifted, the first lifting drive 133 can drive the lifting base 131 to move along the second direction Y, so that the first lifting member 132 moves along the mounting groove 1311, thereby allowing the first lifting member 132 to pass through the first through hole 121 and lift the workpiece 30 to a first height. In this way, automatic lifting can be achieved, improving the working efficiency of the worktable.

[0069] In one embodiment, see [reference] Figures 7 to 9 As shown, the first lifting drive component 133 includes a first drive component 1331, a first guide component 1332, and a movable component 1333. The first drive component 1331 is located on the side of the material support plate 12 near the support component 11, and is connected to the top material base 131. The first drive component 1331 is used to drive the top material base 131 to move along the second direction Y. The first guide component 1332 is connected to the side of the material support plate 12 near the support component 11 and extends along the second direction Y. The movable component 1333 is connected to the top material base 131 and is movably connected to the first guide component 1332.

[0070] Therefore, when the first driving member 1331 drives the top material base 131 to move along the second direction Y, the first guide member 1332 and the movable member 1333 cooperate to play a guiding role, thereby improving the stability of the top material base 131 moving along the second direction Y, and converting the movement of the top material base 131 along the second direction Y into the movement of the first lifting member 132 along the thickness direction of the supporting plate 12, thus improving the smoothness and stability of the movement conversion.

[0071] Optionally, the first lifting drive 133 may include a plurality of first drive components 1331, which may be connected to the top material base 131 via a floating joint. The first drive component 1331 includes, but is not limited to, a cylinder.

[0072] In one embodiment, see [reference] Figures 8 to 9 As shown, the first guide member 1332 is provided with a through groove 1332a and a slot 1332b; the through groove 1332a passes through the first guide member 1332 along the second direction Y, and the top material base 131 passes through the through groove 1332a; the slot 1332b is arranged parallel to the through groove 1332a and is parallel to the through groove 1332a; the movable member 1333 includes a first roller 1333a, the first roller 1333a is rotatably connected to the top material base 131, and the first roller 1333a rolls and engages in the slot 1332b.

[0073] Specifically, there can be two slots 1332b, which are located on both sides of the through slot 1332a and connected to it; the movable part 1333 includes two first rollers 1333a, which are rotatably connected to both sides of the top material base 131, and the two first rollers 1333a are rolled in the two slots 1332b in a one-to-one correspondence.

[0074] Therefore, when the first driving member 1331 drives the top material base 131 to move along the second direction Y, the through groove 1332a can play a guiding and limiting role. The two first rollers 1333a roll within the two slots 1332b, which can improve the stability of the top material base 131 moving along the second direction Y. This converts the movement of the top material base 131 along the second direction Y into the movement of the first lifting member 132 along the thickness direction of the supporting plate 12, improving the smoothness and stability of the movement conversion. In addition, there is rolling friction between the first rollers 1333a and the slots 1332b, and there is also rolling friction between the first lifting member 132 and the mounting groove 1311 of the top material base 131. This reduces the frictional resistance of each moving pair in the first top material mechanism 13, ensures the smooth operation of the top material action of the first top material mechanism 13, reduces the wear of each part in the first top material mechanism 13, and thus extends the service life of the first top material mechanism 13, thereby extending the service life of the worktable 10.

[0075] In one embodiment, see [reference] Figure 6 , Figure 8 As shown, the first lifting member 132 includes a first lifting part 1321, a first connecting part 1322, and a rotating part 1323. The first connecting part 1322 is rolled in the mounting groove 1311. The first lifting part 1321 passes through the first through hole 121 and is connected to the first connecting part 1322. The rotating part 1323 is rotatably connected to the end of the first lifting part 1321 away from the first connecting part 1322.

[0076] Therefore, the first connecting part 1322 facilitates the rolling engagement between the first lifting member 132 and the mounting groove 1311. The first lifting part 1321 passes through the first through hole 121 and is connected to the first connecting part 1322. When the ejector base 131 moves along the second direction Y, the mounting groove 1311 moves relative to the first lifting member 132. When the first connecting part 1322 of the first lifting member 132 rolls along the mounting groove 1311, the frictional resistance between the first lifting member 132 and the mounting groove 1311 of the ejector base 131 is reduced, and the smoothness of the movement of the first lifting member 132 along the mounting groove 1311 is improved. This ensures the smooth operation of the ejector action of the first lifting member 132, so as to smoothly lift the workpiece 30, thereby improving the processing efficiency of the workpiece 30 and thus improving production efficiency. In addition, by rotatably connecting the rotating part 1323 to the end of the first lifting part 1321 away from the first connecting part 1322, when the workpiece 30 is transferred, the rotating part 1323 will rotate relative to the side of the workpiece 30 that is closer to the support plate 12. That is, the friction between the rotating part 1323 and the workpiece 30 is rolling friction rather than sliding friction, thereby reducing the risk of scratching the workpiece 30 when it is transferred.

[0077] Optionally, the rotating part 1323 may include, but is not limited to, rollers.

[0078] In one embodiment, see [reference] Figure 8 As shown, the first connecting part 1322 includes a connecting shaft 1322a, which is rotatably connected to the end of the first lifting part 1321 away from the rotating part 1323, and the two ends of the connecting shaft 1322a are rolled into the mounting groove 1311.

[0079] Therefore, by means of connecting shaft 1322a, one end of the first lifting member 132 can be easily rolled into the mounting groove 1311, which reduces the frictional resistance between the first lifting member 132 and the mounting groove 1311 of the top material base 131, improves the smoothness of the first lifting member 132 moving along the mounting groove 1311, and ensures the smooth operation of the first lifting member 132 in its material-lifting action, so as to smoothly lift the workpiece 30, thereby improving the processing efficiency of the workpiece 30 and thus improving production efficiency; in addition, it can reduce the frictional resistance between the first lifting member 132 and the top material base 131, improve the reliability of the first material-lifting mechanism 13, and reduce the wear of each part, thereby extending the service life of the worktable 10.

[0080] Optionally, a first through hole (not shown) may be provided at the end of the first lifting part 1321 away from the rotating part 1323. The axial direction of the first through hole is perpendicular to the axial direction of the first lifting part 1321. The connecting shaft 1322a passes through the first through hole and is clearance-fitted with the first through hole. In this way, the connecting shaft 1322a can be easily rotatably connected to the end of the first lifting part 1321 away from the rotating part 1323.

[0081] Optionally, the first lifting part 1321 can be a pin, and the connecting shaft 1322a can be a roller. The pin and roller have simple structures and low processing costs, thereby reducing the cost of the first lifting mechanism 13 and the cost of the entire worktable 10.

[0082] In one embodiment, see [reference] Figure 8 As shown, the first connecting part 1322 includes a connecting shaft 1322a and a second roller (not shown in the figure). The connecting shaft 1322a is connected to the end of the first lifting part 1321 away from the rotating part 1323. The second roller is connected to the connecting shaft 1322a and is tactilely connected to the mounting groove 1311.

[0083] Specifically, there can be two second rollers, which are connected to the two ends of the connecting shaft 1322a respectively, and are rotatably connected in the mounting groove 1311.

[0084] This facilitates the connection between the first connecting part 1322 and the first lifting part 1321, and also facilitates the rolling fit of the first connecting part 1322 within the mounting groove 1311.

[0085] In one embodiment, the first lifting portion 1321 includes a first lifting sub-portion (not shown) and a second lifting sub-portion (not shown). The first lifting sub-portion is connected to the first connecting portion 1322. One end of the second lifting sub-portion is connected to the end of the first lifting sub-portion away from the first connecting portion 1322, and the other end of the second lifting sub-portion is connected to the rotating portion. The second lifting sub-portion is capable of rotating relative to the first lifting sub-portion about a third direction Z, which is perpendicular to the second direction Y.

[0086] Therefore, by rotating the second lifting part relative to the first lifting part about a third direction, the arrangement angle of the rotating part 1323 on the first lifting part 1321 can be easily adjusted, thereby facilitating the transfer of the workpiece 30.

[0087] It should be noted that the third direction Z can be the thickness direction of the support plate 12.

[0088] Optionally, both the first lifting part and the second lifting part can be rod-shaped members, and the first lifting part and the second lifting part can be threaded together. This facilitates the connection between the second lifting part and the first lifting part, allowing the second lifting part to rotate relative to the first lifting part about a third direction Z.

[0089] In one embodiment, see [reference] Figure 8 As shown, the mounting groove 1311 has a first contact surface 1311a and a second contact surface 1311b. Both the first contact surface 1311a and the second contact surface 1311b extend along the first direction X, and the end of the first lifting member 132 near the top material base 131 can move along the first contact surface 1311a and the second contact surface 1311b.

[0090] Therefore, when the first lifting member 132 moves along the mounting groove 1311, one end of the first lifting member 132 rolls along the first contact surface 1311a and the second contact surface 1311b, so that the other end of the first lifting member 132 can extend into and protrude from the first through hole 121 to lift the workpiece 30, reduce the frictional resistance between the first lifting member 132 and the mounting groove 1311 of the material lifting base 131, improve the smoothness of the first lifting member 132 moving along the mounting groove 1311, and ensure the smooth operation of the material lifting action of the first lifting member 132 to smoothly lift the workpiece 30, thereby improving the processing efficiency of the workpiece 30 and thus improving production efficiency.

[0091] It should be noted that both the first contact surface 1311a and the second contact surface 1311b are inclined surfaces extending along the first direction X.

[0092] In one embodiment, see [reference] Figure 7 and Figure 8As shown, the top material base 131 is also provided with a guide groove 1312 on the side near the material support plate. The guide groove 1312 extends along the second direction Y. The guide groove 1312 is connected to the mounting groove 1311, and the first lifting member 132 passes through the guide groove 1312.

[0093] Therefore, when the top material base 131 moves along the second direction Y, the first lifting member 132 moves along the mounting groove 1311 and the guide groove 1312, which can reduce the probability of the first lifting member 132 shifting position during the movement, so that the first lifting member 132 can smoothly pass through the first through hole 121 and lift the workpiece 30.

[0094] In one embodiment, see [reference] Figures 1 to 3 As shown, a positioning element 123 is provided on the side of the material support plate 12 away from the first top material mechanism 13. The positioning element 123 is used to position the workpiece 30. The positioning element 123 has a second height along the third direction Z. The third direction Z is perpendicular to the second direction Y. The second height is less than the first height.

[0095] Therefore, by positioning the workpiece 30 using the positioning member 123, displacement of the workpiece 30 during processing can be avoided, thus improving the processing accuracy of the workpiece 30. By making the second height of the positioning member 123 smaller than the first height, the workpiece 30 can be easily lifted and removed from the positioning member 123 using the first ejector mechanism 13, thereby facilitating the transfer of the workpiece 30 after processing.

[0096] Optionally, multiple positioning elements 123 can be provided on the side of the support plate 12 away from the first ejector mechanism 13, and positioning holes (not shown) that cooperate with the positioning elements 123 can be provided on the workpiece 30. This enables multi-point positioning of the workpiece 30 and improves the positioning effect. The positioning element 123 can be a positioning pin. The positioning pin has a simple structure and low processing cost, thereby reducing the cost of the worktable 10.

[0097] In one embodiment, see [reference] Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7As shown, it also includes a second lifting mechanism 14, which includes a lifting plate 141, a second lifting member 142, and a second lifting drive member 143. The lifting plate 141 is located on the side of the supporting plate 12 near the support member 11; the lifting plate 141 has a second through hole 1411 corresponding to the first through hole 121; the lifting base 131 is located on the side of the lifting plate 141 away from the supporting plate 12 and is movably connected to the lifting plate 141; the first lifting member 132 passes through the second through hole 1411; the first lifting drive member 133... The first lifting member 142 is located on the side of the top plate 141 away from the support plate 12; the second lifting member 142 is located on the side of the top plate 141 close to the support plate 12; the support plate 12 is provided with a third through hole 122, and the second lifting member 142 passes through the third through hole 122; the second lifting drive member 143 is connected to the top plate 141, and the second lifting drive member 143 is used to drive the top plate 141 to move along the third direction Z, so that the second lifting member 142 protrudes out of the third through hole 122, so as to lift the workpiece 30 to a third height, the third height being less than the first height.

[0098] Therefore, when the workpiece 30 is finished and needs to be unloaded, the second lifting drive 143 first drives the top plate 141 to move along the third direction Z, so that the second lifting member 142 protrudes from the third through hole 122, thereby lifting the workpiece 30 to a third height; the first lifting drive 133 drives the top base 131 to move along the second direction Y, so that the first lifting member 132 moves along the mounting groove 1311, the first lifting member 132 passes through the first through hole 121 and lifts the workpiece 30 to a first height. Since the first height is greater than the second height, the workpiece 30 can be separated from the positioning member 123. Since the first lifting member 132 is provided with a rotating part 1323, the risk of scratching the workpiece 30 during transfer can be reduced.

[0099] When loading and processing of workpiece 30 is required, the end of the first lifting member 132 away from the top material base 131 is pre-positioned to protrude from the side of the support plate 12 away from the top material base 131. The distance between the end of the first lifting member 132 away from the top material base 131 and the support plate 12 is a first height. The end of the second lifting member 142 away from the top material plate 141 is pre-positioned to protrude from the side of the support plate 12 away from the top material base 131. The distance between the end of the second lifting member 142 away from the top material plate 141 and the support plate 12 is a third height. The workpiece 30 to be processed is then placed on the first lifting member 132. Adjust the workpiece 30 so that the positioning hole of the workpiece 30 is aligned with the positioning member 123. Then, use the first lifting drive member 133 to drive the top material base 131 to move along the second direction Y, so that the first lifting member 132 slides along the first through hole 121 and moves toward the direction close to the top material base 131 until the workpiece 30 contacts the second lifting member 142. After the second lifting member 142 receives the workpiece 30, use the second lifting drive member 143 to drive the top material plate 141 to move away from the support plate 12 until the workpiece 30 is placed on the support plate 12 and the positioning member 123 passes into the positioning hole on the workpiece 30.

[0100] It should be noted that the correspondence between the second through hole 1411 and the first through hole 121 means that the axis of the first through hole 121 and the axis of the second through hole 1411 are approximately coincident.

[0101] The third height can be understood as the distance between the workpiece 30 and the support plate 12 when the workpiece 30 is lifted by the second lifting member 142, that is, the end of the second lifting member 142 away from the top plate 141 protrudes from the side of the support plate 12 away from the top base 131, and the distance between the end of the second lifting member 142 away from the top plate 141 and the support plate 12.

[0102] In one embodiment, the third height is smaller than the second height.

[0103] Therefore, the stroke of the second lifting component along the third direction is shorter, and the worktable does not need to reserve more space along the third direction, which can reduce the height of the worktable, lower the center of gravity of the worktable 10, and improve the stability of the worktable 10.

[0104] In one embodiment, see [reference] Figure 8 As shown, a second guide member 1412 is provided in the second through hole 1411, and a first lifting member 132 passes through the second guide member 1412. The second guide member 1412 is used to guide the first lifting member 132 to move along the third direction Z.

[0105] Therefore, since the second through hole 1411 corresponds to the first through hole 121, by setting the second guide member 1412 in the second through hole 1411, the first lifting member 132 passes through the second guide member 1412. The second guide member 1412 is used to guide the first lifting member 132 to move along the third direction Z, which can improve the smoothness and stability of the first lifting member 132 moving along the third direction Z, improve the movement accuracy of the first lifting member 132, and ensure the smooth operation of the first lifting member 132's material lifting action, so as to smoothly lift the workpiece 30, thereby improving the processing efficiency of the workpiece 30 and thus improving production efficiency.

[0106] Optionally, the second guide 1412 may include, but is not limited to, a linear bearing.

[0107] In one embodiment, see [reference] Figure 1 and Figure 2 As shown, the second lifting drive component 143 includes an expansion component 1431, which is located on the side of the top plate 141 away from the support plate 12. The expansion component 1431 is connected to the top plate 141 and can expand or contract to drive the top plate 141 to move along the third direction Z.

[0108] Therefore, when the expansion member 1431 is inflated, it drives the top plate 141 to move toward the support plate 12; when the expansion member 1431 contracts, it drives the top plate 141 to move away from the support plate 12.

[0109] In another embodiment, the second lifting drive 143 may also include a motor or a cylinder.

[0110] In one embodiment, see [reference] Figure 3 As shown, the second top material mechanism 14 also includes a third guide member 144. The third guide member 144 is located on the side of the top material plate 141 close to the support member 11. The top material plate 141 is provided with a guide hole 1413. The axial direction of the guide hole 1413 is parallel to the axial direction of the third through hole 122. The third guide member 144 passes through the guide hole 1413.

[0111] Therefore, when the second lifting drive 143 drives the top plate 141 to move, the guide hole 1413 and the third guide 144 cooperate to provide guidance for the top plate 141, preventing the top plate 141 from shaking during movement, thereby improving the smoothness and stability of the movement of the second lifting member 142 along the third through hole 122.

[0112] Optionally, see Figure 3 As shown, the third guide member 144 can be disposed on the bearing assembly 20, and the third guide member 144 can be a rod-shaped structure.

[0113] In one embodiment, a linear bearing is disposed within the guide hole 1413, and a third guide member 144 passes through the linear bearing.

[0114] Therefore, the linear bearing can restrict the movement of the third guide member 144 along the axial direction of the guide hole 1413, preventing the top plate 141 from shaking during movement, thereby improving the smoothness and stability of the movement of the second lifting member 142 along the third through hole 122.

[0115] In one embodiment, see [reference] Figure 8 As shown, there is a first gap S between the top material base 131 and the top material plate 141.

[0116] Therefore, even if the machining accuracy of the top plate 141 is low or the top plate 141 is deformed due to movement, it can still be ensured that there is no interference between the top base 131 and the top plate 141, ensuring the normal movement of the first top mechanism 13, thereby improving the reliability of the worktable 10, while reducing the machining requirements of the top plate 141 and reducing the cost of each part of the worktable 10.

[0117] Secondly, see Figure 2 As shown in the illustration, this application also provides a PCB processing equipment, including a support component 20, a processing component, and a worktable 10 as described in any of the above embodiments. Both the worktable 10 and the processing component are connected to the support component 20. The processing component is used to process the PCB placed on the support plate 12. This improves the processing efficiency of the PCB processing equipment and increases production efficiency.

[0118] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0119] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
