Description

Technical Field

[0001] The present application relates to the technical field of processing equipment, and in particular to a pressing mechanism and pressing equipment. Background Art

[0002] In the related art, manual assembly is usually used with the help of tools such as wooden ropes to knock workpieces such as plastic nails to be pressed together in order to assemble parts such as the body of a child car chair and a cushion (if the preparation material is EPS, where the full name of EPS in English is expandable polystyrene, and the Chinese name is expanded polystyrene) to form an assembly. During the assembly process, if the force applied by the operator is too large, it is easy to cause the workpieces such as plastic nails to be pressed together to break, or cause surface damage to parts such as the body of the child car chair and the cushion; if the force applied by the operator is too small, it is easy to cause workpieces such as plastic nails in the assembly to loosen, resulting in a low yield rate of the assembly. Therefore, how to effectively solve the problems of breakage of workpieces to be pressed together, surface damage to parts to be assembled, and low yield rate of the assembly caused by manual assembly has become an urgent problem to be solved. Utility Model Content

[0003] The embodiments of the present application provide a pressing mechanism and pressing equipment, which can solve the problems in the related art caused by manual assembly, such as breakage of the workpiece to be pressed, surface damage of the parts to be assembled, and low yield rate of the assembly.

[0004] In the first aspect, the embodiment of the present application provides a pressing mechanism; the pressing mechanism includes a frame, a conveying assembly, a carrier and an adsorption pressing assembly; the conveying assembly is installed on the frame; the carrier is installed on the driving end of the conveying assembly; the adsorption pressing assembly includes a first driving member, a cylinder, a second driving member and a mold core; the first driving member is installed on the carrier; the cylinder is used to connect with an external vacuum generator and is installed on the driving end of the first driving member; the second driving member is installed on the carrier; the mold core is installed on the driving end of the second driving member, the mold core passes through the upper port of the cylinder and is in the shape of an inner wall surface of the cylinder into a seal; the conveying assembly is configured to drive the carrier to move along a preset trajectory so that the carrier switches between a preset material picking position and a preset material discharge position; at the preset material picking position, the first driving member drives the cylinder to move along a first direction until the lower end of the cylinder contacts the workpiece to be pressed to adsorb the workpiece to be pressed; at the preset material discharge position, the first driving member drives the cylinder to move along the first direction until the lower end of the cylinder is adjacent to the hole position of the part to be assembled, and then the second driving member drives the mold core to move along the first direction to press the workpiece to be pressed into the hole position of the part to be assembled to assemble to form an assembly.

[0005] According to the laminating mechanism of the present invention, when the carrier is in a preset material pickup position, the first driving member drives the cylinder to move in a first direction toward the workpiece to be pressed, so that the lower end of the cylinder contacts the workpiece to be pressed to absorb the workpiece to be pressed. The first driving member then drives the cylinder to move in the opposite direction with the workpiece to be pressed, thereby completing the workpiece suction operation. The conveying assembly drives the carrier along a preset trajectory to move the carrier to a preset material discharge position. When the carrier is in the preset material discharge position, the first driving member first drives the cylinder to move in the first direction toward the assembly to be assembled, so that the lower end of the cylinder is adjacent to the hole of the assembly to be assembled. The second driving member then drives the mold core to move in the first direction toward the assembly to form an assembly. The workpiece to be pressed, which is absorbed by the lower end of the cylinder, is driven into the hole of the assembly to form an assembly under the action of a pressure differential. The second driving member then drives the mold core to move in the first direction away from the assembly. The first driving member then drives the cylinder to move in the first direction away from the assembly, thereby completing the workpiece lamination operation. The conveyor assembly drives the carrier along a pre-set trajectory, returning it to the pre-set pick-up position. This cyclical operation enables batch assembly, effectively reducing assembly errors caused by manual assembly, minimizing the possibility of workpiece breakage and surface damage to assembled components, and improving the assembly yield rate. It also effectively reduces labor and costs.

[0006] In some embodiments, the adsorption and pressing assembly further includes a first mounting member, and the cylinder is mounted on the driving end of the first driving member via the first mounting member.

[0007] Based on the above embodiment, by designing the first mounting member, the first mounting member serves as an intermediate connecting member between the cylinder and the driving end of the first driving member. On the one hand, it is used to support the cylinder to provide sufficient installation space for the cylinder, and on the other hand, it connects the driving end of the first driving member to reduce the difficulty of assembly between the cylinder and the driving end of the first driving member.

[0008] In some embodiments, the first driving member includes a first cylinder mounted on the supporting member, and the telescopic rod of the first cylinder serves as the driving end of the first driving member and is connected to the first mounting member; the adsorption and pressing assembly also includes a guide member, which is connected to the first mounting member and the supporting member; wherein the telescopic rod of the first cylinder performs a telescopic movement along the first direction to drive the first mounting member to perform a telescopic movement along the first direction, thereby driving the guide member to slide relative to the supporting member along the first direction.

[0009] Based on the above embodiment, by designing a guide member, the telescopic rod of the first cylinder drives the first mounting member to perform telescopic movement along the first direction, while the guide member also slides along the first direction. The guide member provides support for the telescopic movement of the first mounting member in the first direction to enhance the stability of the telescopic movement of the first mounting member along the first direction, thereby realizing effective adsorption of the cylinder on the workpiece to be pressed.

[0010] In some embodiments, the adsorption and pressing assembly further includes a second mounting member, and the mold core is mounted on the driving end of the second driving member via the second mounting member.

[0011] Based on the above embodiment, by designing the second mounting member, the second mounting member serves as an intermediate connecting member between the mold core and the driving end of the second driving member. On the one hand, it is used to support the mold core to provide sufficient installation space for the mold core, and on the other hand, it connects the driving end of the second driving member to reduce the difficulty of assembly between the mold core and the driving end of the second driving member.

[0012] In some embodiments, the second driving member includes a second cylinder mounted on the supporting member, and the telescopic rod of the second cylinder is connected to the second mounting member as the driving end of the second driving member; wherein, at a preset discharge position, the telescopic rod of the second cylinder extends along the first direction to drive the mold core to move along the first direction to press the workpiece to be pressed into the hole of the part to be assembled to form an assembly.

[0013] Based on the above embodiment, by designing the second cylinder, at the preset discharge position, the telescopic rod of the second cylinder extends along the first direction to drive the mold core to move along the first direction toward the part to be assembled, so that the workpiece to be pressed adsorbed on the lower port of the cylinder is driven into the hole of the part to be assembled under the action of the pressure difference to assemble to form an assembly; then the telescopic rod of the second cylinder contracts along the first direction to drive the mold core to move along the first direction away from the assembly to achieve the resetting of the mold core.

In this way, the number of times the conveying component drives the carrier to move between the preset material picking position and the preset material discharge position can be reduced, so as to shorten the assembly time and improve the assembly efficiency of the pressing mechanism.

[0035] The pressing mechanism 10 includes a frame 11, a conveying assembly 12, a carrier 13 and an adsorption pressing assembly 14. The conveying assembly 12 is mounted on the frame 11.

The conveying assembly 12 is configured to drive the carrier 13 to move along a preset trajectory so that the carrier 13 switches between a preset material picking position and a preset material discharge position; at the preset material picking position, the first driving member 141 drives the cylinder 142 to move along the first direction MM' until the lower end of the cylinder 142 contacts the workpiece to be pressed to adsorb the workpiece to be pressed; at the preset material discharge position, the first driving member 141 drives the cylinder 142 to move along the first direction MM' until the lower end of the cylinder 142 is adjacent to the hole position of the part to be assembled, and then the second driving member 143 drives the mold core 144 to move along the first direction MM' to press the workpiece to be pressed into the hole position of the part to be assembled to assemble to form an assembly.

[0036] The following combination Figures 1-6The specific structure of the pressing mechanism 10 will be introduced in detail. It should be noted that in the embodiments of the present application, the pressing mechanism 10 can be used to press a workpiece to be pressed onto a fitting to form an assembly; among them, the product form of the workpiece to be pressed can be but is not limited to plastic nails, pins, buttons, etc.; the product form of the fitting can be but is not limited to a car child seat body and a cushion (such as the preparation material is EPS, where the full English name of EPS is expandable polystyrene, and the Chinese name is expanded polystyrene), buttons, gaskets, etc. For example, the pressing mechanism 10 can press a plastic nail as the workpiece to be pressed into the hole positions of the car child seat body and the cushion as the fitting to assemble and form an assembly; for another example, the pressing mechanism 10 can also press a pin as the workpiece to be pressed into the hole position of a button as the fitting to assemble and form an assembly; for yet another example, the pressing mechanism 10 can also press a button as the workpiece to be pressed into the hole position of a gasket as the fitting to assemble and form an assembly.

[0037] As Figure 1-Figure 3 shown, the pressing mechanism 10 includes a frame body 11, a conveying component 12, a carrier 13 and an adsorption and pressing component 14.

[0038] The frame body 11 serves as the support of the pressing mechanism 10. The specific structure of the frame body 11 is not limited here, and designers can make reasonable designs according to actual needs; for example, the frame body 11 can be but is not limited to a structure similar to a "C" shape.

[0039] The conveying component 12 serves as the transmission module of the pressing mechanism 10, and the specific structure of the conveying component 12 will be introduced in detail below.

[0040] The conveying component 12 is installed on the frame body 11. The specific connection method between the conveying component 12 and the frame body 11 is not limited here, and designers can make reasonable designs according to actual needs; for example, the conveying component 12 can be but is not limited to being detachably connected to the frame body 11 by at least one of the ways such as screwing, clamping or plugging; for another example, the conveying component 12 can also be but is not limited to being non-detachably connected to the frame body 11 by ways such as welding or riveting.

[0041] The carrier 13 serves as the carrier of the pressing mechanism 10. The specific structure of the carrier 13 is not limited here, and designers can make reasonable designs according to actual needs; for example, the carrier 13 can be but is not limited to a plate-like structure or a frame structure.

[0042] The carrier 13 is mounted on the driving end of the conveying assembly 12. The specific connection method between the carrier 13 and the driving end of the conveying assembly 12 is not limited here, and designers can reasonably design it according to actual needs. For example, the carrier 13 can be, but is not limited to, detachably connected to the driving end of the conveying assembly 12 by at least one of screwing, snapping, or plugging. For another example, the carrier 13 can also be, but is not limited to, non-detachably connected to the driving end of the conveying assembly 12 by welding or riveting.

[0043] like Figure 1-Figure 3 As shown, the adsorption and pressing component 14 serves as an execution module of the pressing mechanism 10. On the one hand, the adsorption and pressing component 14 is used to perform an adsorption operation on the workpiece to be pressed, and on the other hand, the adsorption and pressing component 14 is used to perform a pressing operation on the component to be pressed.

[0044] The adsorption and pressing assembly 14 includes a first driving member 141 , a cylinder 142 , a second driving member 143 and a mold core 144 .

[0045] The first drive member 141 serves as a power source for the suction and pressing assembly 14, driving the cylinder 142 to move in the first direction MM'. The specific form of the first drive member 141 is not limited herein; designers may design it based on practical needs. For example, the first drive member 141 may include, but is not limited to, a cylinder or a linear motor.

[0046] The first driving member 141 is mounted on the carrier 13. The specific connection method between the first driving member 141 and the carrier 13 is not limited here, and designers can reasonably design it according to actual needs. For example, the first driving member 141 can be, but is not limited to, detachably connected to the carrier 13 through at least one of a screw connection, a snap connection, or a plug connection. For another example, the first driving member 141 can also be, but is not limited to, non-detachably connected to the carrier 13 through welding or riveting.

[0047] like Figure 4-Figure 6 As shown, the cylinder 142 serves as an adsorption component for the adsorption and pressing assembly 14 , and the cylinder 142 is a cylindrical structure with two ends open.

[0048] The cylinder 142 is used to connect to an external vacuum generator (not shown in the figure). The side wall of the cylinder 142 has a vacuum hole 142a connected to its inner cavity. The vacuum hole 142a is connected to an adapter (not shown in the figure), and the adapter is connected to the external vacuum generator through a plastic hose (not shown in the figure).

[0049] The cylinder 142 is mounted on the driving end of the first driving member 141. The specific connection method between the cylinder 142 and the driving end of the first driving member 141 is not limited here, and designers can make reasonable designs based on actual needs; for example, when the first driving member 141 includes a cylinder, the telescopic rod of the cylinder is connected to the cylinder 142 as the driving end, and the cylinder 142 can be, but is not limited to, fixedly connected to the telescopic rod of the cylinder by at least one of screw connection, clip connection, or plug connection; for another example, when the first driving member 141 includes a linear motor, the mover of the linear motor is connected to the cylinder 142 as the driving end, and the cylinder 142 can be, but is not limited to, fixedly connected to the mover of the linear motor by at least one of screw connection, clip connection, or plug connection.

[0050] The second drive member 143 serves as another power source for the suction and pressing assembly 14, driving the mold core 144 to move in the first direction MM'. The specific form of the second drive member 143 is not limited herein; designers may design it based on practical needs. For example, the second drive member 143 may include, but is not limited to, a pneumatic cylinder or a linear motor.

[0051] The second driving member 143 is mounted on the carrier 13. The specific connection method between the second driving member 143 and the carrier 13 is not limited here, and designers can reasonably design it according to actual needs. For example, the second driving member 143 can be, but is not limited to, detachably connected to the carrier 13 through at least one of a screw connection, a snap connection, or a plug connection. For another example, the second driving member 143 can also be, but is not limited to, non-detachably connected to the carrier 13 through welding or riveting.

[0052] The mold core 144 serves as a pressing part of the adsorption pressing assembly 14 . The mold core 144 passes through the upper end of the cylinder 142 and forms a seal with the inner wall surface of the cylinder 142 .

[0053] The mold core 144 is mounted on the driving end of the second driving member 143. The specific connection method between the mold core 144 and the driving end of the second driving member 143 is not limited here, and designers can make reasonable designs based on actual needs; for example, when the second driving member 143 includes a cylinder, the telescopic rod of the cylinder is connected to the mold core 144 as the driving end, and the mold core 144 can be, but is not limited to, fixedly connected to the telescopic rod of the cylinder by at least one of screw connection, clip connection, or plug connection; for another example, when the second driving member 143 includes a linear motor, the mover of the linear motor is connected to the mold core 144 as the driving end, and the mold core 144 can be, but is not limited to, fixedly connected to the mover of the linear motor by at least one of screw connection, clip connection, or plug connection.

[0054] like Figure 1-Figure 3As shown, the conveyor assembly 12 is configured to drive the carrier 13 along a preset trajectory to switch the carrier 13 between a preset pick-up position and a preset discharge position. The "preset pick-up position" is the position of the carrier 13 when the cylinder 142 is performing a suction operation on the workpiece to be pressed; the "preset discharge position" is the position of the carrier 13 when the mold core 144 is performing a pressing operation on the workpiece to be pressed.

[0055] It is understandable that the entire adsorption and pressing assembly 14 is installed on the carrier 13. When the conveying assembly 12 drives the carrier 13 to move along the preset trajectory, the adsorption and pressing assembly 14 installed on the carrier 13 will also follow the carrier 13 to move along the preset trajectory.

[0056] At the preset material picking position, the first driving member 141 drives the cylinder 142 to move along the first direction MM' until the lower end of the cylinder 142 contacts the workpiece to be pressed to absorb the workpiece to be pressed. It should be noted that when the lower end of the cylinder 142 contacts the workpiece to be pressed, the external vacuum generator is activated, and the workpiece to be pressed is tightly fitted with the lower end of the cylinder 142 under the action of the external vacuum generator until the negative pressure reaches the preset condition. The first driving member 141 then drives the cylinder 142 to move along the first direction MM' with the workpiece to be pressed away from the feeding mechanism 20 (described below, used to provide the workpiece to be pressed). At this time, the cylinder 142 completes the absorption operation of the workpiece to be pressed.

[0057] At the preset discharge position, the first driving member 141 drives the cylinder 142 to move along the first direction MM' until the lower end of the cylinder 142 is adjacent to the hole of the part to be assembled, and then the second driving member 143 drives the mold core 144 to move along the first direction MM' to press the workpiece to be pressed into the hole of the part to be assembled to form an assembly. It should be noted that before the second driving member 143 drives the mold core 144 to move along the first direction MM', the air pressure in the inner cavity of the cylinder 142 is lower than the external atmospheric pressure, so that the workpiece to be pressed is adsorbed on the lower end of the cylinder 142. During the process of the second driving member 143 driving the mold core 144 to move along the first direction MM', the volume of the inner cavity of the cylinder 142 gradually decreases, causing the air pressure in the inner cavity of the cylinder 142 to gradually increase to greater than the external atmospheric pressure. The workpiece to be pressed, which was originally adsorbed on the lower end of the cylinder 142, is driven into the hole of the part to be assembled under the action of the pressure difference to form an assembly.

[0058] Based on the laminating mechanism 10 of the embodiment of the present application, when the carrier 13 is in the preset material removal position, the first driving member 141 drives the cylinder 142 to move in the first direction MM' toward the workpiece to be pressed, so that the lower end of the cylinder 142 contacts the workpiece to be pressed to absorb the workpiece to be pressed. Then, the first driving member 141 drives the cylinder 142 to move in the opposite direction along the first direction MM' with the workpiece to be pressed. At this time, the cylinder 142 completes the absorption operation of the workpiece to be pressed. The conveying assembly 12 drives the carrier 13 along the preset trajectory to move the carrier 13 to the preset material discharge position. When the carrier 13 is in the preset discharge position, the first drive member 141 first drives the cylinder 142 to move along the first direction MM' with the workpiece to be pressed toward the part to be assembled, so that the lower end of the cylinder 142 is adjacent to the hole of the part to be assembled. Then, the second drive member 143 drives the mold core 144 to move along the first direction MM' toward the part to be assembled, so that the workpiece to be pressed, which is adsorbed on the lower end of the cylinder 142, is driven into the hole of the part to be assembled under the action of the pressure difference to form an assembly. Then, the second drive member 143 drives the mold core 144 to move along the first direction MM' away from the assembly, and the first drive member 141 drives the cylinder 142 to move along the first direction MM' away from the assembly. At this time, the mold core 144 completes the pressing operation of the workpiece to be pressed. The conveying assembly 12 drives the carrier 13 to move along the preset trajectory to move the carrier 13 back to the preset material removal position. Such cyclic operation can realize batch assembly, effectively reduce the assembly errors caused by manual assembly, reduce the possibility of breakage of the workpiece to be pressed and damage to the surface of the assembled parts, improve the yield rate of the assembly, and also effectively reduce manpower input and reduce costs.

[0059] like Figure 2 and Figure 4 As shown, the adsorption and pressing assembly 14 further includes a first mounting member 145 ; the cylinder 142 is mounted on the driving end of the first driving member 141 via the first mounting member 145 .

[0060] Among them, the first mounting member 145 serves as an intermediate connecting member between the cylinder 142 and the driving end of the first driving member 141. The specific structure of the first mounting member 145 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the first mounting member 145 can be, but is not limited to, a plate-shaped structure or a frame structure. The specific connection method between the cylinder 142 and the first mounting member 145 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the outer wall surface of the cylinder 142 near the upper end is provided with an external thread, and the first mounting member 145 is provided with a threaded hole, and the cylinder 142 and the first mounting member 145 are connected by a threaded connection to achieve relative fixation between the two. The specific connection method between the first mounting member 145 and the driving end of the first driving member 141 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the first mounting member 145 can be, but is not limited to, fixedly connected to the driving end of the first driving member 141 by a locking screw.

[0061] The first mounting member 145 is designed as an intermediate connector between the cylinder 142 and the driving end of the first driving member 141. It is used to support the cylinder 142 to provide sufficient installation space for the cylinder 142, and to connect the driving end of the first driving member 141 to reduce the difficulty of assembly between the cylinder 142 and the driving end of the first driving member 141. It should be noted that the number of cylinders 142 can be one or more (two or more); and regardless of whether there are one or more cylinders 142, the one or more cylinders 142 can be connected to the driving end of the first driving member 141 through the same first mounting member 145.

[0062] like Figure 2 and Figure 4 As shown, the first driving member 141 includes a first cylinder mounted on the support member 13; the telescopic rod of the first cylinder serves as the driving end of the first driving member 141 and is connected to the first mounting member 145. The suction and pressing assembly 14 also includes a guide member 146; the guide member 146 is connected to the first mounting member 145 and the support member 13. The telescopic rod of the first cylinder telescopes in the first direction MM', driving the first mounting member 145 to telescope in the first direction MM', thereby driving the guide member 146 to slide relative to the support member 13 in the first direction MM'.

[0063] The first cylinder may be, but is not limited to, fixedly connected to the carrier 13 by means of screws. The guide member 146 may be, but is not limited to, a guide rod or a guide block. For example, when the guide member 146 is a guide rod, the guide rod extends along the first direction MM' and is slidably connected to the carrier 13. The end of the guide rod may be, but is not limited to, fixedly connected to the first mounting member 145 by means of screws. For another example, when the guide member 146 is a guide block, the guide block may be, but is not limited to, fixedly connected to the first mounting member 145 by means of screws, and the side wall of the carrier 13 may be provided with a guide rail that is slidably connected to the guide block.

[0064] By designing the guide member 146, the telescopic rod of the first cylinder drives the first mounting member 145 to perform telescopic movement along the first direction MM', while the guide member 146 also slides along the first direction MM'. The guide member 146 provides support for the telescopic movement of the first mounting member 145 in the first direction MM', so as to enhance the stability of the telescopic movement of the first mounting member 145 along the first direction MM', thereby realizing the effective adsorption of the cylinder 142 on the workpiece to be pressed.

[0065] like Figure 2 and Figure 4 As shown, the adsorption and pressing assembly 14 further includes a second mounting member 147 ; the mold core 144 is mounted on the driving end of the second driving member 143 via the second mounting member 147 .

[0066] Among them, the second mounting member 147 serves as an intermediate connecting member between the mold core 144 and the driving end of the second driving member 143. The specific structure of the second mounting member 147 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the second mounting member 147 can be, but not limited to, a plate-shaped structure or a frame structure. The specific connection method between the mold core 144 and the second mounting member 147 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the end of the mold core 144 can be, but not limited to, fixedly connected to the second mounting member 147 by means of locking screws. The specific connection method between the second mounting member 147 and the driving end of the second driving member 143 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the second mounting member 147 can be, but not limited to, fixedly connected to the driving end of the second driving member 143 by means of locking screws.

[0067] By designing the second mounting member 147, which serves as an intermediate connector between the mold core 144 and the driving end of the second driving member 143, the second mounting member 147 is used to support the mold core 144 to provide sufficient installation space for the mold core 144, and to connect the driving end of the second driving member 143 to reduce the difficulty of assembly between the mold core 144 and the driving end of the second driving member 143. It should be noted that the number of mold cores 144 can be one or more (two or more); and regardless of whether there are one or more mold cores 144, the one or more mold cores 144 can be connected to the driving end of the second driving member 143 through the same second mounting member 147. When both the mold cores 144 and the cylinders 142 are multiple in number, the multiple mold cores 144 are provided in a one-to-one correspondence with the multiple cylinders 142.

[0068] like Figure 2 and Figure 4 As shown, the second driving member 143 comprises a second cylinder mounted on the carrier 13; the telescopic rod of the second cylinder, serving as the driving end of the second driving member 143, is connected to the second mounting member 147. At the preset discharge position, the telescopic rod of the second cylinder extends in the first direction MM' to drive the mold core 144 in the first direction MM' until the workpiece to be pressed is pressed into the hole of the assembly to form the assembly. The second cylinder can be fixedly connected to the carrier 13 by, but is not limited to, screws. By designing the second cylinder, at the preset discharge position, the telescopic rod of the second cylinder extends along the first direction MM' to drive the mold core 144 to move along the first direction MM' toward the part to be assembled, so that the workpiece to be pressed adsorbed on the lower port of the cylinder 142 is driven into the hole of the part to be assembled under the action of the pressure difference to assemble to form an assembly; then the telescopic rod of the second cylinder retracts along the first direction MM' to drive the mold core 144 to move along the first direction MM' away from the assembly to achieve the reset of the mold core 144.

[0069] Of course, the press-fit adsorption assembly further includes another guide member 148, which is fixedly connected to the second mounting member 147 and slidably connected to the carrier 13. The other guide member 148 can be, but is not limited to, another guide rod or another guide block; for example, when the other guide member 148 is another guide rod, the other guide rod extends along the first direction MM' and is slidably connected to the carrier 13, and the end of the other guide rod can be, but is not limited to, fixedly connected to the second mounting member 147 by means of a locking screw; for another example, when the other guide member 148 is another guide block, the other guide block can be, but is not limited to, fixedly connected to the second mounting member 147 by means of a locking screw, and the side wall of the carrier 13 is provided with a guide rail slidably connected to the other guide block. By designing another guide member 148, the telescopic rod of the second cylinder drives the second mounting member 147 to perform telescopic movement along the first direction MM', while the other guide member 148 also slides along the first direction MM'. The other guide member 148 provides support for the telescopic movement of the second mounting member 147 in the first direction MM', so as to enhance the stability of the telescopic movement of the second mounting member 147 along the first direction MM', thereby realizing effective pressing of the mold core 144 on the workpiece to be pressed.

[0070] like Figure 2 As shown, the number of adsorption and pressing components 14 is multiple, and the multiple adsorption and pressing components 14 are arranged at intervals along the second direction NN'. For example, the number of adsorption and pressing components 14 can be, but is not limited to, two, three, four, five, six or more. By designing the number of adsorption and pressing components 14 to be multiple, when the carrier 13 is in the preset material picking position, the first driving member 141 and the cylinder 142 in the multiple adsorption and pressing components 14 can complete the adsorption of multiple workpieces to be pressed, and when the carrier 13 is in the preset material discharge position, the first driving member 141, the cylinder 142, the second driving member 143 and the mold core 144 in the multiple adsorption and pressing components 14 can complete the pressing of multiple workpieces to be pressed to assemble into multiple assemblies. In this way, the number of times the conveying component 12 drives the carrier 13 to move between the preset material picking position and the preset material discharge position can be reduced, so as to shorten the assembly time and improve the assembly efficiency of the pressing mechanism 10.

[0071] like Figure 1As shown, the conveying assembly 12 includes a first conveying unit 121 and a second conveying unit 122. The first conveying unit 121 is mounted on the frame 11. The second conveying unit 122 is mounted on the driving end of the first conveying unit 121. The carrier 13 is mounted on the driving end of the second conveying unit 122. The driving end of the first conveying unit 121 moves along the second direction NN' to move the carrier 13 from directly above the preset material collection position to directly above the preset material discharge position. The driving end of the second conveying unit 122 descends along the first direction MM' to move the carrier 13 from directly above the preset material discharge position to the preset material discharge position. The driving end of the first conveying unit 121 moves along the second direction NN' to move the carrier 13 from directly above the preset material discharge position to directly above the preset material collection position. The driving end of the second conveying unit 122 descends along the first direction MM' to move the carrier 13 from directly above the preset material collection position to the preset material collection position. The second direction NN′ is a horizontal direction, and the first direction MM′ is a vertical direction.

[0072] It should be noted that at the preset pick-up position, after the cylinder 142 completes the suction operation of the workpiece to be pressed, the driving end of the second conveyor unit 122 moves upward in the first direction MM' to transfer the carrier 13 from the preset pick-up position to directly above the preset pick-up position. At the preset discharge position, after the mold core 144 completes the pressing operation of the workpiece to be pressed, the driving end of the second conveyor unit 122 moves upward in the first direction MM' to transfer the carrier 13 from the preset discharge position to directly above the preset discharge position. In addition, the driving end of the second conveying unit 122 has a larger movement stroke for the lifting movement along the first direction MM', while the driving end of the first driving member 141 has a smaller movement stroke for the lifting movement along the first direction MM'; in this way, when the supporting member 13 is in the preset material picking position, the cylinder 142 will only make a small downward movement along the first direction MM' under the action of the first driving member 141, so that the lower end of the cylinder 142 can contact the workpiece to be pressed; when the supporting member 13 is in the preset material discharge position, the cylinder 142 will also only make a small downward movement along the first direction MM' under the action of the first driving member 141, so that the lower end of the cylinder 142 can be set adjacent to the hole position of the part to be assembled.

[0073] Specifically, if Figure 1-Figure 2 As shown, the first conveying unit 121 includes a conveying rail 1211 and a third driving member 1212; the conveying rail 1211 is installed on the frame 11 and extends along the second direction NN', and the second conveying unit 122 is slidingly connected to the conveying rail 1211; the third driving member 1212 is installed on the frame 11, and the driving end of the third driving member 1212 is connected to the second conveying unit 122, and the driving end of the third driving member 1212 can move along the second direction NN' to drive the second conveying unit 122 to move along the second direction NN'.

[0074] The conveying track 1211 can be, but is not limited to, fixedly connected to the frame 11 by means of screws. The third driving member 1212 can be, but is not limited to, a cylinder or a linear motor; the third driving member 1212 can be, but is not limited to, fixedly connected to the frame 11 by means of screws. The specific connection method between the second conveying unit 122 and the driving end of the third driving member 1212 is not limited here, and designers can make reasonable designs based on actual needs; for example, when the third driving member 1212 includes a cylinder, the telescopic rod of the cylinder serves as the driving end and is connected to the second conveying unit 122, and the second conveying unit 122 can be, but is not limited to, fixedly connected to the telescopic rod of the cylinder by at least one of screw connection, snap connection, or plug connection; for another example, when the third driving member 1212 includes a linear motor, the mover of the linear motor serves as the driving end and is connected to the second conveying unit 122, and the second conveying unit 122 can be, but is not limited to, fixedly connected to the mover of the linear motor by at least one of screw connection, snap connection, or plug connection.

[0075] By designing the third driving member 1212, the driving end of the third driving member 1212 moves along the second direction NN' to drive the second conveying unit 122 to move along the second direction NN', so that the supporting member 13 can move back and forth between just above the preset material picking position and just above the preset material discharging position.

[0076] In the embodiment of the present application, the third driving member 1212 includes a first linear motor, the stator of the first linear motor is installed on the frame 11 , and the mover of the first linear motor serves as the driving end of the third driving member 1212 and is connected to the second conveying unit 122 .

[0077] like Figure 1-Figure 2 As shown, the second conveying unit 122 includes a bracket 1221 and a fourth driving member 1222; the bracket 1221 is installed on the driving end of the third driving member 1212 and is slidingly connected to the conveying track 1211; the fourth driving member 1222 is installed on the bracket 1221, and the driving end of the fourth driving member 1222 is connected to the supporting member 13, and the driving end of the fourth driving member 1222 can move along the first direction MM' to drive the supporting member 13 to move along the first direction MM'.

[0078] Among them, the bracket 1221 can be, but is not limited to, fixedly connected to the driving end of the third driving member 1212 by means of locking screws. The fourth driving member 1222 can be, but is not limited to, including a cylinder or a linear motor; the fourth driving member 1222 can be, but is not limited to, fixedly connected to the bracket 1221 by means of locking screws. The specific connection method between the supporting member 13 and the driving end of the fourth driving member 1222 is not limited here, and designers can make reasonable designs based on actual needs; for example, when the fourth driving member 1222 includes a cylinder, the telescopic rod of the cylinder is connected to the supporting member 13 as the driving end, and the supporting member 13 can be, but is not limited to, fixedly connected to the telescopic rod of the cylinder by at least one of screw connection, clip connection or plug connection; for another example, when the fourth driving member 1222 includes a linear motor, the mover of the linear motor is connected to the supporting member 13 as the driving end, and the supporting member 13 can be, but is not limited to, fixedly connected to the mover of the linear motor by at least one of screw connection, clip connection or plug connection.

[0079] By designing the fourth driving member 1222, the driving end of the fourth driving member 1222 moves along the first direction MM' to drive the supporting member 13 to move along the first direction MM', so that the supporting member 13 can move back and forth between directly above the preset material picking position and the preset material picking position, and can move back and forth between directly above the preset material discharge position and the preset material discharge position.

[0080] In the embodiment of the present application, the fourth driving member 1222 includes a second linear motor, the stator of the second linear motor is installed on the bracket 1221, and the mover of the second linear motor is connected to the supporting member 13 as the driving end of the fourth driving member 1222.

[0081] The following describes the working principle of the pressing mechanism 10 by taking the workpiece to be pressed as a plastic nail and the parts to be assembled as a car child chair body and a cushion as an example, specifically:

[0082] Step 1: The carrier 13 is located directly above the preset material removal position, and the mover of the second linear motor moves downward along the first direction MM' to move the carrier 13 to the preset material removal position;

[0083] Step 2: The telescopic rod of the first cylinder extends in the first direction MM' to drive the cylinder 142 to move downward in the first direction MM', so that the lower end of the cylinder 142 contacts the plastic nail; the external vacuum generator is activated until the negative pressure reaches a preset condition; the telescopic rod of the first cylinder retracts in the first direction MM', so that the cylinder 142 and the plastic nail move upward in the first direction MM';

[0084] Step 3: The mover of the second linear motor moves upward in the first direction MM' to move the carrier 13 to directly above the preset material picking position; the mover of the first linear motor moves forward in the second direction NN' to move the carrier 13 to directly above the preset material discharge position; the mover of the second linear motor moves downward in the first direction MM' to move the carrier 13 to the preset material discharge position;

[0085] Step 4: The telescopic rod of the first cylinder extends in the first direction MM' to cause the cylinder 142 to move downward along the first direction MM' along with the workpiece to be pressed, so that the lower end of the cylinder 142 is adjacent to the holes of the car baby chair body and the cushion; the telescopic rod of the second cylinder extends in the first direction MM' to drive the mold core 144 to move downward in the first direction MM', so that the mold core 144 presses the plastic nails into the holes of the car baby chair body and the cushion to assemble the assembly; the telescopic rod of the second cylinder contracts in the first direction MM' to drive the mold core 144 to move upward in the first direction MM' until it is reset; the telescopic rod of the first cylinder contracts in the first direction MM' to cause the cylinder 142 to move upward in the first direction MM' until it is reset;

[0086] Step 5: The mover of the second linear motor moves upward in the first direction MM' to move the carrier 13 to just above the preset material discharge position; the mover of the first linear motor moves in the opposite direction in the second direction NN' to move the carrier 13 to just above the preset material removal position;

[0087] This cycle repeats to achieve batch assembly. It should be noted that when there are multiple adsorption and pressing components 14, only after the cylinders 142 in the multiple adsorption and pressing components 14 have adsorbed the plastic nails in sequence according to the preset order, will the mover of the second linear motor move upward along the first direction MM' to move the carrier 13 directly above the preset material picking position. Similarly, only after the mold cores 144 in the multiple adsorption and pressing components 14 have been pressed into the plastic nails in sequence according to the preset order, will the mover of the second linear motor move upward along the first direction MM' to move the carrier 13 directly above the preset material discharge position. The adsorption operation performed on the cylinders 142 in the multiple adsorption and pressing components 14 can be performed synchronously or asynchronously. Similarly, the pressing operation performed on the mold cores 144 in the multiple adsorption and pressing components 14 can be performed synchronously or asynchronously.

[0088] Please refer to Figure 7As shown, in a second aspect, the present application provides a pressing device 1, which includes a workbench, a feeding mechanism 20, a jig, and the aforementioned pressing mechanism 10. The feeding mechanism 20 is mounted on the workbench and is used to provide workpieces to be pressed. The jig is mounted on the workbench and is used to support the parts to be assembled. The frame 11 is mounted on the workbench.

[0089] Based on the pressing device 1 in the embodiment of the present application, which has the above-mentioned pressing mechanism 10, batch assembly can be realized, effectively reducing the assembly errors caused by manual assembly, reducing the possibility of breakage of the workpiece to be pressed and damage to the surface of the parts to be assembled, and improving the yield rate of the assembly. In addition, it can also effectively reduce personnel input and reduce costs.
