Description

Technical Field

[0001] This application relates to the field of processing, and more particularly to an assembly device and assembly method. Background Technology

[0002] When processing existing products in molds, it is necessary to assemble and embed small workpieces. Usually, manual labor or external power equipment is used to place the workpieces on the product located inside the mold, resulting in poor positioning accuracy. Summary of the Invention

[0003] In view of this, it is necessary to provide an assembly device and assembly method to improve the positioning accuracy of the workpiece.

[0004] An embodiment of this application provides an assembly apparatus, comprising:

[0005] The mold includes an upper mold base and a lower mold base arranged opposite to each other along a first direction, wherein the lower mold base has a molding cavity on the side facing the upper mold base;

[0006] A lifting mechanism is disposed within the lower mold base and slidably connected to the lower mold base along the first direction;

[0007] The feeding mechanism is partially located within the lower mold base and between the lifting mechanism and the forming cavity. The lifting mechanism is used to lift the workpiece supplied by the feeding mechanism, which can move the workpiece to a preset forming position within the forming cavity.

[0008] The pushing mechanism includes a first pushing member and a retaining member. The first pushing member is connected to one side of the upper mold base, and the retaining member is connected to one side of the lower mold base and is disposed corresponding to the first pushing member. When the upper mold base and the lower mold base are closed and the molding cavity is sealed, the first pushing member is configured to push the retaining member to resist the lifting mechanism, thereby restricting the lifting mechanism and positioning the workpiece in the molding cavity, and molding the product by injection molding outside the workpiece.

[0009] The technical effects of the embodiments of this application are as follows: In the above-mentioned assembly device, the workpiece of the feeding mechanism is lifted by the lifting mechanism to place the workpiece in the molding cavity. At the same time, when the upper mold base moves toward the lower mold base, the first pusher pushes the holding member to limit the stroke of the lifting mechanism in the first direction, so as to maintain the position of the workpiece in the molding cavity and achieve precise positioning of the workpiece.

[0010] In some embodiments of this application, the lifting mechanism includes a lifting drive, a first lifting member, and a second lifting member. The lifting drive is connected to the lower mold base, and the first lifting member is connected to the first lifting member. The first lifting member is slidably connected to the lower mold base along the first direction. One end of the second lifting member is connected to the side of the first lifting member facing the upper mold base, and the other end is used to pass through the feeding mechanism to push the workpiece in the feeding mechanism into the molding cavity. The second lifting member is also used to pass through the molding cavity and push the product out of the molding cavity.

[0011] The technical effects of the embodiments of this application are as follows: by setting a first lifting member, the second lifting member is driven by the lifting drive member to lift the workpiece in the feeding mechanism, so that the workpiece can be supported in the molding cavity, so that the product outside the workpiece can be injection molded around the workpiece. At the same time, the first lifting member is driven by the lifting drive member to drive the second lifting member to lift the injection molded product, so that the product can be detached from the molding cavity, thereby improving the demolding efficiency of the product.

[0012] In some embodiments of this application, the feeding mechanism includes a feeding component and a pushing component. The feeding component is partially located in the lower mold base. The feeding component has a receiving groove on the side facing the upper mold base. The receiving groove is used to receive the workpiece to be ejected into the molding cavity. The end of the feeding component located in the lower mold base has a ejector port communicating with the receiving groove. The pushing component is slidably connected to the receiving groove and is used to push the workpiece to the ejector port. The second lifting component can pass through the ejector port and is used to lift the workpiece.

[0013] In some embodiments of this application, the feeding mechanism further includes a guide and an elastic member. The feeding member has two spaced-apart protrusions. The guide is connected between the two protrusions. The pusher is slidably connected to the guide. The elastic member is sleeved on the outside of the guide and elastically abuts against the pusher and one of the protrusions. The pusher is used to slide along the receiving groove under the elastic action of the elastic member to push the workpiece to the top feed port.

[0014] The technical effects of the embodiments of this application are as follows: the workpiece to be assembled is stored in the material receiving tank. After the lifting component pushes a workpiece in the material receiving tank from the top material port to the forming cavity, the pushing component slides continuously along the guide under the elastic force of the elastic component to push the next workpiece in the feeding component to the top material port, thereby realizing automatic continuous feeding and improving feeding efficiency.

[0015] In some embodiments of this application, the retaining member includes a sliding part, a retaining part, and an elastic part that elastically abuts against the sliding part and the retaining part. The sliding part is connected to the lower mold base. The retaining part is disposed on the side of the sliding part facing the first lifting member in a second direction. The first lifting member is provided with a retaining groove. The first pushing member is configured to push the sliding part to move and compress the elastic part. The sliding part drives the retaining part to move, so that the retaining part is disposed in the retaining groove. The second direction is intersected with the first direction.

[0016] The technical effects of the embodiments of this application are as follows: by providing a retaining groove on the side wall of the first lifting member, when the first lifting member drives the second lifting member to push the workpiece in the feeding mechanism to the molding cavity, the first pushing member pushes the sliding part to move toward the first lifting member, and the elastic part is driven by the pushing force of the sliding part to drive the retaining part to retain the retaining groove, so as to limit and position the lifting mechanism in the lower mold base, and reduce the risk of the workpiece lifted by the lifting mechanism shifting during the product injection molding process.

[0017] In some embodiments of this application, the pushing mechanism further includes a second pushing member, one end of which is connected to the first lifting member, and the other end of which is slidably engaged with the sliding part along the first direction. The second pushing member is used to drive the sliding part to reset to its initial position.

[0018] The technical effects of the embodiments of this application are as follows: by setting a second pusher, after the product in the molding cavity has been injection molded, the second pusher pushes the sliding part to drive the holding part to disengage from the holding groove, so that the first lifting part is freed from the restriction of the holding part, and the lifting mechanism can be reset to the initial position to perform the next lifting action.

[0019] In some embodiments of this application, the sliding part is provided with a first sliding hole, the hole wall of the first sliding hole has a first inclined wedge surface, and the end of the first push member away from the upper mold base has a second inclined wedge surface that cooperates with the first inclined wedge surface, so as to drive the sliding part to move towards the holding part in the second direction by the movement of the first push member in the first direction;

[0020] The sliding part is also provided with a second sliding hole spaced apart from the first sliding hole. The wall of the second sliding hole has a third inclined wedge surface. The end of the second pusher away from the first lifting member has a fourth inclined wedge surface that cooperates with the third inclined wedge surface, so that the movement of the second pusher in the first direction drives the sliding part to move away from the holding part in the second direction.

[0021] The technical effects of the embodiments of this application are as follows: By providing a first wedge surface on the first sliding hole and a second wedge surface on the first pushing member, during the mold closing process of the upper mold base toward the lower mold base, the second wedge surface slides and connects with the first wedge surface, so that the sliding part drives the holding part to abut against the first lifting member, thereby improving the stability of the lifting mechanism when lifting the workpiece. At the same time, by providing a third wedge surface on the second sliding hole and a fourth wedge surface on the second pushing member, after the workpiece is assembled onto the product, the third wedge surface slides and connects with the fourth wedge surface, so that the sliding part drives the holding part to disengage from the first lifting member, so that the lifting mechanism can return to its initial position and prepare for the next lifting action.

[0022] In some embodiments of this application, the assembly device further includes a feeding and fixing mechanism, which is rotatably connected to the lower mold base. The feeding and fixing mechanism is located on one side of the feeding mechanism and is used to abut against the end of the feeding mechanism that protrudes from the lower mold base.

[0023] The technical effects of the embodiments of this application are as follows: by setting a feeding fixing mechanism, after the feeding mechanism is pushed into the lower mold base, the feeding fixing mechanism is rotated so that the feeding fixing mechanism supports the feeding mechanism, thereby reducing the risk that the feeding mechanism will automatically exit the lower mold base during the workpiece assembly process.

[0024] In some embodiments of this application, the assembly device further includes a workpiece fixing mechanism connected to the upper mold base, which is used to adsorb the workpiece lifted by the lifting mechanism into the molding cavity when the upper mold base and the lower mold base are closed.

[0025] The technical effects of the embodiments of this application include: by setting an adsorption component in the upper mold base, when the upper ejector rod pushes the workpiece onto the product, the adsorption component can adsorb the end of the product away from the upper ejector rod, thereby improving the stability of the workpiece when it is assembled onto the product.

[0026] This application also provides an assembly method, using the above-described assembly apparatus, comprising the following steps:

[0027] S1. Arrange the workpieces in the feeding mechanism, which is installed in the lower mold base;

[0028] S2. The upper mold base and the lower mold base close to seal the molding cavity. The lifting mechanism passes through the feeding mechanism to lift the workpiece in the feeding mechanism into the molding cavity. The first pusher pushes the holding member to hold and connect to the lifting mechanism to maintain the position of the workpiece in the molding cavity.

[0029] S3. Injection molding is performed on the outside of the workpiece to form the product.

[0030] In the above-mentioned assembly device, the workpiece of the feeding mechanism is lifted by the lifting mechanism to place the workpiece in the forming cavity. At the same time, when the upper mold base moves toward the lower mold base, the first pusher pushes the holding member to limit the stroke of the lifting mechanism in the first direction, so as to maintain the position of the workpiece in the forming cavity and achieve precise positioning of the workpiece.

[0103] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. The terms "vertical," "horizontal," "left," "right," "top," "bottom," and similar expressions used herein are for illustrative purposes only and are not intended to limit the application.

[0104] It is understood that when describing the parallel / perpendicular setup of two components, the included angle between the two components is allowed to have a tolerance of ±10% relative to the standard parallel / perpendicular setup.

[0105] This application provides an assembly apparatus, including:

[0106] The mold includes an upper mold base and a lower mold base arranged opposite each other along a first direction, and the lower mold base has a molding cavity on the side facing the upper mold base.

[0107] The lifting mechanism is located inside the lower mold base and is slidably connected to the lower mold base along the first direction.

[0108] The feeding mechanism is partially located within the lower mold base and between the lifting mechanism and the forming cavity. The lifting mechanism is used to lift the workpiece supplied by the feeding mechanism, allowing the workpiece to move to the preset forming position within the forming cavity.

[0109] The pushing mechanism includes a first pushing member and a holding member. The first pushing member is connected to one side of the upper mold base, and the holding member is connected to one side of the lower mold base and is provided corresponding to the first pushing member. The first pushing member is used to push the holding member against the lifting mechanism when the upper mold base and the lower mold base are closed to seal the molding cavity, so as to limit the lifting mechanism and position the workpiece in the molding cavity, and to form a product by injection molding outside the workpiece.

[0110] In the above-mentioned assembly device, the workpiece of the feeding mechanism is lifted by the lifting mechanism to place the workpiece in the forming cavity. At the same time, when the upper mold base moves toward the lower mold base, the first pusher pushes the holding member to limit the stroke of the lifting mechanism in the first direction, so as to maintain the position of the workpiece in the forming cavity and achieve precise positioning of the workpiece.

[0111] The following describes some embodiments of this application in detail with reference to the accompanying drawings.

[0112] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The assembly device 100 provided in the embodiments of this application is used to assemble the workpiece 20 onto the product 30. The assembly device 100 includes a mold 10, a lifting mechanism 40, a feeding mechanism 50, and a pushing mechanism 70.

[0113] The mold 10 includes an upper mold base 11 and a lower mold base 12 arranged opposite to each other along a first direction Z. The lower mold base 12 has a molding cavity 13 on the side facing the upper mold base 11. The first direction Z is a vertical direction.

[0114] The lifting mechanism 40 is located inside the lower mold base 12 and is slidably connected to the lower mold base 12 along the first direction Z. The feeding mechanism 50 is partially located inside the lower mold base 12 and between the lifting mechanism 40 and the forming cavity 13. The lifting mechanism 40 is used to lift the workpiece 20 supplied in the feeding mechanism 50, so that the workpiece 20 can move to the preset forming position in the forming cavity 13.

[0115] Specifically, the lifting mechanism 40 includes a lifting drive 41, a first lifting member 42, and a second lifting member 43. The lifting drive 41 is connected to the lower mold base 12, and the transmission end of the lifting drive 41 is drivenly connected to the first lifting member 42. The first lifting member 42 is slidably connected to the lower mold base 12 along the first direction Z. One end of the second lifting member 43 is connected to the side of the first lifting member 42 facing the upper mold base 11, and the other end is used to pass through the feeding mechanism 50 to push the workpiece 20 in the feeding mechanism 50 into the molding cavity 13. The second lifting member 43 can move the workpiece 20 to a preset molding position in the molding cavity 13 so that the product 30 outside the workpiece 20 can be injection molded around the workpiece 20. The second lifting member 43 is also used to pass through the molding cavity 13 to push the injection molded product 30 out of the molding cavity 13, so that the product 30 can be detached from the molding cavity 13, improving the demolding efficiency of the product 30.

[0116] Optionally, the lifting drive 41 is a cylinder.

[0117] Understandably, the end of the second lifting member 43 furthest from the first lifting member 42 is shaped to mimic the form of the workpiece 20, thus adapting to the shape of the workpiece 20. The end of the second lifting member 43 that contacts the workpiece 20 can be adjusted according to the actual size or shape of the workpiece 20 to improve the versatility of the lifting mechanism 40.

[0118] The lifting mechanism 40 also includes a lifting elastic element 44, which elastically abuts between the first lifting element 42 and the lower mold base 12, providing a buffering effect during the process of the first lifting element 42 lifting towards the upper mold base 11.

[0119] The lifting mechanism 40 also includes a positioning member 45. One end of the positioning member 45 is connected to the first lifting member 42, and the other end of the positioning member 45 extends in the first direction Z toward the direction away from the first lifting member 42 and is used to extend into the molding cavity 13. When the lifting mechanism 40 pushes the product 30 out of the molding cavity 13, the positioning member 45 is used to lift the injection-molded product 30 to improve the stability of the lifting mechanism 40 when lifting the product 30.

[0120] Please refer to the following: Figure 2 , Figure 4 and Figure 5 The feeding mechanism 50 includes a feeding component 51 and a pushing component 52. The feeding component 51 is partially located in the lower mold base 12. The feeding component 51 has a receiving groove 511 on the side facing the upper mold base 11. The receiving groove 511 is used to receive the workpiece 20 to be ejected into the molding cavity 13. The end of the feeding component 51 located in the lower mold base 12 has an ejection port 512 that communicates with the receiving groove 511. The pushing component 52 is slidably connected to the receiving groove 511 and is used to push the workpiece 20 to the ejection port 512. The second lifting component 43 can pass through the ejection port 512 and is used to lift the workpiece 20.

[0121] The feeding mechanism 50 also includes a guide 53 and a feeding elastic member 54. The feeding member 51 has two protrusions 513 on both ends of the side away from the upper mold base 11. The guide 53 is connected between the two protrusions 513. The bottom wall of the material receiving groove 511 has a sliding hole 5111. One end of the pusher 52 passes through the sliding hole 5111 and is sleeved and connected to the outside of the guide 53. The other end of the pusher 52 is held and connected inside the material receiving groove 511. The feeding elastic member 54 is sleeved on the outside of the guide 53 and elastically abuts against the pusher 52 and one of the protrusions 513. The pusher 52 is used to slide along the material receiving groove 511 under the elastic action of the feeding elastic member 54 to push the workpiece 20 to the top material port 512.

[0122] The workpiece 20 to be assembled is stored in the material receiving tank 511. After the lifting component pushes one workpiece 20 in the material receiving tank 511 from the top material port 512 into the forming cavity 13, the pushing component 52 slides continuously along the guide component 53 under the elastic force of the feeding elastic component 54, so as to push the next workpiece 20 in the feeding component 51 to the top material port 512, thereby realizing automatic continuous feeding and improving feeding efficiency.

[0123] Understandably, the feeding mechanism 50 is detachably connected to the lower mold base 12. After the workpiece 20 in the feeding mechanism 50 is assembled, the feeding mechanism 50 can be disassembled from the lower mold base 12 to replenish the workpiece 20 in the feeding mechanism 50, and then reinstalled into the lower mold base 12 so that the lifting mechanism 40 can continue to lift the workpiece 20 in the feeding mechanism 50 into the molding cavity 13.

[0124] In this embodiment, four feeding mechanisms 50 are provided, and the four feeding mechanisms 50 are arranged at intervals along the third direction Y inside the lower mold base 12. Optionally, the number of feeding mechanisms 50 can also be 1, 2, 3, 5, etc., depending on the actual assembly requirements. Correspondingly, the second lifting member 43 in the lifting mechanism 40, which is used to lift the workpiece 20 in the feeding mechanisms 50, is arranged at intervals on the first lifting member 42 in sequence according to the number of feeding mechanisms 50. Multiple lifting members simultaneously lift the workpiece 20 in multiple feeding mechanisms 50, improving feeding efficiency. The third direction Y is perpendicular to the first direction Z.

[0125] Please refer to the following: Figure 1 , Figure 4 and Figure 6 In some embodiments, the assembly device 100 further includes a feeding fixing mechanism 60, which is rotatably connected to the lower mold base 12 and is located on one side of the feeding mechanism 50. The feeding fixing mechanism 60 abuts against the end of the feeding mechanism 50 that protrudes from the lower mold base 12. By providing the feeding fixing mechanism 60, after the feeding mechanism 50 is pushed into the lower mold base 12, the feeding fixing mechanism 60 can be rotated to hold the feeding mechanism 50 in place, reducing the risk that the feeding mechanism 50 may spontaneously retract from the lower mold base 12 during the assembly of the workpiece 20.

[0126] The feeding and fixing mechanism 60 includes a rotating shaft 61 and a handle 62. One end of the rotating shaft 61 is connected to the handle 62, and the other end of the rotating shaft 61 is rotatably connected to the lower mold base 12. The handle 62 has a stop 621 on the side near the feeding component 51, which is used to hold the end of the feeding component 51 that is exposed outside the lower mold base 12. After the feeding component 51 is pushed into the lower mold base 12, the handle 62 is rotated to rotate the rotating shaft 61, so that the stop 621 restricts the position of the feeding component 51 in the lower mold base 12, reducing the risk of the feeding component 51 falling off the lower mold base 12 during assembly.

[0127] The feeding and fixing mechanism 60 also includes a fastener 63, a limiting sleeve 64, and a limiting elastic element 65. One end of the fastener 63 is connected to the handle 62, and the other end of the fastener 63 passes through the rotating shaft 61 and extends to the outside of the rotating shaft 61. The limiting sleeve 64 is fitted onto the portion of the rotating shaft 61 that protrudes from the handle 62, limiting the length of the rotating shaft 61 as it rotates into the lower mold base 12, reducing the risk of damage to the feeding element 51 caused by excessive pressure from the stop portion 621 due to the excessive length of the rotating shaft 61 screwed into the lower mold base 12. The limiting elastic element 65 is fitted onto the portion of the rotating shaft 61 located inside the handle 62, acting as a buffer when the handle 62 drives the rotating shaft 61 to rotate into the lower mold base 12.

[0128] In this embodiment, there are two feeding and fixing mechanisms 60, each including two stop portions 621 to fix the positions of the four feeding mechanisms 50 within the lower mold base 12. Depending on actual assembly requirements, the number of feeding and fixing mechanisms 60 can also be 1, 3, 4, 5, etc., with each feeding and fixing mechanism 60 corresponding to two feeding mechanisms 50.

[0129] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the pushing mechanism 70 includes a first pushing member 71 and a holding member 72. The first pushing member 71 is connected to one side of the upper mold base 11, and the holding member 72 is connected to one side of the lower mold base 12 and is disposed corresponding to the first pushing member 71. When the upper mold base 11 and the lower mold base 12 close the mold and seal the molding cavity 13, the first pushing member 71 is configured to push the holding member 72 to abut against the lifting mechanism 40, thereby limiting the lifting mechanism 40 and positioning the workpiece 20 within the molding cavity 13, and molding the product 30 by injection molding outside the workpiece 20.

[0130] In this embodiment, the pushing mechanism 70 is provided in two sets and is respectively located on opposite sides of the upper mold base 11 and the lower mold base 12, thereby improving the stability of the position of the limiting lifting mechanism 40 within the lower mold base 12.

[0131] Please refer to the following: Figure 2 , Figure 3 , Figure 7 and Figure 8 In some embodiments, the retaining member 72 includes a sliding portion 721, a retaining portion 722, and an elastic portion 723 that elastically abuts against the sliding portion 721 and the retaining portion 722. The sliding portion 721 is limitedly connected to the lower mold base 12. The retaining portion 722 is disposed on the side of the sliding portion 721 facing the first lifting member 42 in the second direction X. The side wall of the first lifting member 42 near the retaining member 72 is provided with a retaining groove 421. The first pushing member 71 is configured to push the sliding portion 721 to slide and compress the elastic portion 723. The sliding portion 721 drives the retaining portion 722 to move, so that the retaining portion 722 is disposed in the retaining groove 421. The second direction X intersects with the first direction Z. In this embodiment, the second direction X is a horizontal direction.

[0132] By providing a retaining groove 421 on the side wall of the first lifting member 42, when the first lifting member 42 drives the second lifting member 43 to push the workpiece 20 in the feeding mechanism 50 to the molding cavity 13, the first pushing member 71 pushes the sliding part 721 to move toward the first lifting member 42. The elastic part 723 is driven by the pushing force of the sliding part 721 to drive the retaining part 722 to retain the retaining groove 421, so as to limit and position the lifting mechanism 40 in the lower mold base 12, and reduce the risk of the workpiece 20 lifted by the lifting mechanism 40 shifting during the injection molding of the product 30.

[0133] The sliding part 721 has a first sliding hole 7211, and the wall of the first sliding hole 7211 has a first inclined wedge surface 7211A. The end of the first pushing member 71 away from the upper mold base 11 has a second inclined wedge surface 711 that cooperates with the first inclined wedge surface 7211A. This is used to drive the sliding part 721 to move in the second direction X toward the holding part 722, so that the movement of the first pushing member 71 in the first direction Z drives the sliding part 721 to move toward the holding part 722. During the mold closing process of the upper mold base 11 toward the lower mold base 12, the second inclined wedge surface 711 is slidably connected with the first inclined wedge surface 7211A, so that the sliding part 721 drives the holding part 722 to abut against the first lifting member 42, thereby improving the stability of the lifting mechanism 40 when lifting the workpiece 20.

[0134] The retaining member 72 also includes two connecting portions 724, which connect the sliding portion 721 and the retaining portion 722, and are respectively located on both sides of the elastic portion 723. Each connecting portion 724 includes a connecting sleeve 7241 and a connecting bolt 7242. One end of the connecting bolt 7242 is connected to the sliding portion 721, and the other end is slidably connected to the retaining portion 722. The connecting sleeve 7241 is sleeved on the outside of the connecting bolt 7242. One end of the connecting sleeve 7241 extends into the sliding portion 721, and the other end is slidably connected to the retaining portion 722. The connecting portions 724 act as guides when the sliding portion 721 pushes the retaining portion 722 to move, reducing the risk of the retaining portion 722 deviating from its moving track relative to the sliding portion 721.

[0135] The pushing mechanism 70 also includes a second pushing member 73. One end of the second pushing member 73 is connected to the first lifting member 42, and the other end is slidably engaged with the sliding part 721 along the first direction Z. When the first lifting member 42 pushes the second lifting member 43 through the molding cavity 13 to eject the injection-molded product 30 out of the molding cavity 13, the second pushing member 73 drives the sliding part 721 to move away from the holding part 722 along the second direction X. The holding part 72 is used to disengage from the holding groove 421 under the elastic force of the elastic part 723. By providing the second pushing member 73, after the product 30 in the molding cavity 13 has been injection-molded, the second pushing member 73 pushes the sliding part 721 to drive the holding part 722 to disengage from the holding groove 421, so that the first lifting member 42 is freed from the restriction of the holding part 72. The lifting mechanism 40 can then be reset to the initial position for the next lifting action.

[0136] The sliding part 721 is also provided with a second sliding hole 7212 spaced apart from the first sliding hole 7211. The wall of the second sliding hole 7212 has a third inclined wedge surface 7212A. The end of the second pushing member 73 away from the first lifting member 42 has a fourth inclined wedge surface 731 that cooperates with the third inclined wedge surface 7212A. This is used to drive the sliding part 721 to move away from the holding part 722 along the second direction X when the second pushing member 73 moves in the first direction Z. After the workpiece 20 is assembled onto the product 30, the third inclined wedge surface 7212A and the fourth inclined wedge surface 731 are slidably connected, so that the sliding part 721 drives the holding part 722 to disengage from the first lifting member 42, so that the lifting mechanism 40 can be reset to the initial position and prepared for the next lifting action.

[0137] The second pushing member 73 includes a first pushing part 732 and a second pushing part 733 connected to each other. The first pushing part 732 is fixedly connected to the side of the first lifting member 42 away from the second lifting member 43. One end of the second pushing part 733 is connected to the first pushing part 732, and the other end of the second pushing part 733 extends along the first direction Z. A fourth wedge surface 731 is formed at the end of the second pushing part 733 away from the first pushing part 732. In this embodiment, the second pushing member 73 includes two second pushing parts 733, which are spaced apart on the side of the first pushing part 732 facing the upper mold base 11. Correspondingly, the sliding part 721 is provided with two second sliding holes 7212 to improve the stability of the second pushing member 73 when sliding relative to the sliding part 721.

[0138] Please refer to it again. Figure 1 , Figure 2 and Figure 3 In some embodiments, the assembly device 100 further includes a limiting mechanism 80. A limiting housing 121 is provided on the side wall of the lower mold base 12, and the retaining member 72 is limited and connected within the limiting housing 121 by the limiting mechanism 80. The limiting mechanism 80 includes a first limiting member 81 and a second limiting member 82. The first limiting member 81 is fixedly connected within the limiting housing 121. Two spaced-apart limiting holes 7213 are provided on the side of the sliding part 721 facing the upper mold base 11. The end of the first limiting member 81 near the sliding part 721 is slidably connected between the two limiting holes 7213. The second limiting member 82 is connected to the outer wall of the limiting housing 121, and a limiting groove 821 is recessed on the side of the second limiting member 82 facing the lower mold base 12. The end of the sliding part 721 away from the retaining part 722 is limited and connected to the limiting groove 821. The first limiting member 81 and the second limiting member 82 are used to limit the travel of the sliding part 721 in the second direction X, reducing the risk of the holding member 72 disengaging from the lower mold base 12 during the sliding process. At the same time, when the upper mold base 11 moves toward the lower mold base 12, the first pushing member 71 pushes the holding member 72 to limit the travel of the lifting mechanism 40 in the first direction Z, so as to maintain the position of the positioning workpiece 20 in the molding cavity 13 and achieve precise positioning of the workpiece 20.

[0139] Please refer to the following: Figure 1 , Figure 3 and Figure 9 In some embodiments, the assembly device 100 further includes a workpiece fixing mechanism 90, which is connected to the upper mold base 11 and is used to adsorb the workpiece 20 that has been lifted by the lifting mechanism 40 into the molding cavity 13 when the upper mold base 11 and the lower mold base 12 are closed, thereby improving the stability of the workpiece 20 when it is assembled onto the product 30. Optionally, the workpiece fixing mechanism 90 employs vacuum adsorption.

[0140] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 10 In some embodiments, this application also provides an assembly method 200, which uses the above-described assembly apparatus 100 and includes the following steps:

[0141] S1. Arrange the workpiece 20 in the feeding mechanism 50, and the feeding mechanism 50 is installed in the lower mold base 12;

[0142] S2. The upper mold base 11 and the lower mold base 12 close to seal the molding cavity 13. The lifting mechanism 40 passes through the feeding mechanism 50 to lift the workpiece 20 into the molding cavity 13. The first pusher 71 pushes the holding member 72 to hold and connect to the lifting mechanism 40 to maintain the position of the workpiece 20 in the molding cavity 13.

[0143] S3. Injection molding is performed on the outside of workpiece 20 to form product 30.

[0144] Specifically, assembly method 200 includes:

[0145] The workpiece 20 to be injected into the product 30 is assembled on the feeding mechanism 50, and the feeding mechanism 50 is installed in the lower mold base 12. The feeding mechanism 50 is then locked in the position of the feeding mechanism 50 in the lower mold base 12 by the feeding fixing mechanism 60.

[0146] The upper mold base 11 and the lower mold base 12 are in a separated state. The feeding elastic element 54 in the feeding mechanism 50 pushes a workpiece 20 to the position of the ejector 512, that is, the top of the second lifting element 43.

[0147] The upper mold base 11 moves toward the lower mold base 12 to close the mold. The first pusher 71 is slidably connected to the sliding part 721, so that the first wedge surface 7211A and the second wedge surface 711 slide against each other. The sliding part 721 moves toward the holding part 722 so that the holding part 722 abuts against the side wall of the first lifting member 42.

[0148] Driven by the lifting drive 41, the first lifting member 42 moves toward the upper mold base 11, and the holding part 722 slides into the holding groove 421 of the first lifting member 42. At the same time, the first lifting member 42 drives the second lifting member 43 to push the workpiece 20 at the ejector port 512 to the forming cavity 13 formed between the upper mold base 11 and the lower mold base 12. The workpiece fixing mechanism 90 in the upper mold base 11 holds the workpiece 20.

[0149] The lifting drive 41 stops applying force to the first lifting member 42, and the first lifting member 42 rebounds a certain distance away from the upper mold base 11 under the action of the lifting elastic member 44 (in this embodiment, the upper plate rebounds 0.7mm so as to form a 0.7mm gap between the workpiece 20 and the product 30 for glue injection to fix the workpiece 20 and the product 30).

[0150] After injection molding is completed, the upper mold base 11 and the lower mold base 12 separate to open the mold, and the first pusher 71 leaves the sliding part 721.

[0151] The lifting drive 41 applies force to the first lifting member 42 again. The first lifting member 42 drives the second lifting member 43 to push the product 30 out of the molding cavity 13 towards the upper mold base 11. At the same time, the first lifting member 42 drives the second pushing member 73 to slide and connect with the sliding part 721. The third inclined wedge surface 7212A slides with the fourth inclined wedge surface 731. The sliding part 721 drives the holding part 722 to disengage from the holding groove 421, so that the first lifting member 42 drives the second lifting member 43 to return to the initial position for the next assembly operation.

[0152] Those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this application fall within the scope of this application's disclosure.
