Description

Technical Field

[0002] In modern automotive parts manufacturing, many components, such as car keys, require the precise insertion of metal parts into injection-molded parts. Traditionally, this insertion process relies primarily on manual labor, which is inefficient and difficult to meet the demands of large-scale production. On the one hand, manual labor is limited in speed and susceptible to factors such as fatigue, resulting in unstable production cycles. On the other hand, manual labor accuracy is difficult to guarantee when faced with complex or precise insertion tasks, which can easily lead to problems such as misalignment of the metal parts, affecting product quality and increasing the defective rate.

[0003] In order to solve these problems, some automated insertion equipment has appeared in the prior art. However, this insertion setting mainly solves the partial automation of inserting metal parts into injection molded parts. For example, the invention patent with application number CN201410533673.3 discloses an automated press-fitting device for connectors. It uses a cylinder to push and insert, and utilizes a plastic part feed slide and a metal part feed slide, in conjunction with a horizontal push cylinder and a vertical push cylinder, to achieve automatic assembly of plastic and metal parts, thereby improving production efficiency and product qualification rate.

[0080] See also Figures 1 to 10 The present invention provides an automatic assembly device for an injection molded part 1 and a metal part 2, comprising:

[0081] The insertion and positioning platform 3 is used for positioning and placing the injection molded part 1.

[0082] The mold shell conveying device 4 is provided with a mold shell waiting to be grasped station. The mold shell conveying device 4 can continuously convey the injection molded part 1 to the mold shell waiting to be grasped station and stop the injection molded part 1 at the mold shell waiting to be grasped station.

[0083] The molded shell handling device 5 can grab the injection molded part 1 on the molded shell to be grabbed station and transfer it to the insertion positioning platform 3.

[0084] The metal conveying device 6 is provided with a metal-to-be-grabbed station. The metal conveying device 6 can continuously convey the metal piece 2 to the metal-to-be-grabbed station and stop the metal piece 2 at the metal-to-be-grabbed station.

[0085] The metal handling device 7 can grab the metal part 2 on the metal grabbing station and transfer it to the insertion positioning platform 3, and insert the metal part 2 into the injection molded part 1 on the insertion positioning platform 3.

[0086] The main working principle of the automatic assembly equipment involved in the present invention is as follows: During operation, the molded case conveying device 4 continuously conveys the injection molded part 1 to the molded case waiting to be grasped station. The injection molded part 1 stops at the molded case waiting to be grasped station, and the subsequent injection molded parts 1 pause. The molded case handling device 5 grasps the injection molded part 1 at the molded case waiting to be grasped station and transfers it to the insertion positioning table 3. After the injection molded part 1 at the molded case waiting to be grasped station is removed, the molded case conveying device 4 replenishes the injection molded part 1 to the molded case waiting to be grasped station, waiting for the next grasping operation. On the other hand, the metal conveying device 6 conveys the metal part 2 to the metal to be grasped station, and the metal part 2 stops at the metal to be grasped station; the metal handling device 7 grasps the metal part 2 on the metal to be grasped station, and transfers it to the insertion and positioning table 3, and inserts the metal part 2 into the injection molded part 1 located on the insertion and positioning table 3; at the same time, after the metal part 2 on the metal to be grasped station is taken away, the metal handling device 7 replenishes the injection molded part 1 to the metal to be grasped station. After completing the insertion and positioning of the metal part 2 and the injection molded part 1 on the insertion and positioning table 3, the injection molded part 1 can be removed from the insertion and positioning table 3 by the plastic shell conveying device 4 or other means, and then the above operation can be repeated to carry out the insertion and assembly of the next injection molded part 1 and the metal part 2.

[0087] See also Figures 1 to 10 The present invention will be further described below with reference to a specific embodiment:

[0088] The automatic assembly equipment is provided with a control mechanism, which is connected to the insertion positioning table 3, the plastic shell conveying device 4, the plastic shell handling device 5, the metal conveying device 6 and the metal handling device 7, so as to control the automatic movement of each part. The control mechanism can also receive various detection signals as a basis for judgment.

[0089] In this embodiment, see Figure 1 、 Figure 3 and Figure 10As a preferred design, the insertion and positioning platform 3 includes a positioning support block 31 and a clamping mechanism. The positioning support block 31 is provided with a contoured support surface 311, and when the injection molded part 1 is placed on the contoured support surface 311, the two fit together. The clamping mechanism is used to press and secure the injection molded part 1 on the contoured support surface 311, thereby stabilizing the injection molded part 1. The contoured support surface 311 can effectively prevent the injection molded part 1 from being deformed under pressure. Furthermore, the injection molded part 1 is provided with a process hole 101, which is used for installation and connection of the injection molded part 1 or other functions. The insertion and positioning platform 3 also includes a positioning pin 32 provided on the contoured support surface 311. When the injection molded part 1 is placed on the contoured support surface 311, the process hole 101 is fitted onto the positioning pin 32. There are multiple process holes 101 and positioning pins 32, and they are one-to-one opposite to each other to achieve accurate positioning of the injection molded part 1 on the positioning support block 31. In addition, positioning side plates 33 are provided on opposite sides of the positioning support block 31 for guiding the injection molded part 1 to be lowered onto the contoured support surface 311 , thereby reducing misplacement of the injection molded part 1 .

[0090] In this embodiment, see Figure 1 、 Figure 3 and Figure 10 Furthermore, the clamping mechanism includes two presser feet 34 positioned oppositely from one another on either side of the contoured support surface 311, and a presser foot drive assembly that drives the two presser feet 34. The middle portions of the presser feet 34 are rotatably mounted on a base plate, and the positioning support block 31 is fixed to the base plate. The presser foot drive assembly includes a presser foot drive cylinder 35 rotatably mounted on the base plate. The piston rod of the presser foot drive cylinder 35 is hingedly connected to the bottom end of the presser foot 34. The piston rod's telescopic movement drives the presser feet 34 to rotate, causing the upper ends of the presser feet 34 to press against or release the injection molded part 1 placed on the positioning support block 31. A control mechanism is controllably connected to the presser foot drive cylinder 35 to control the automatic movement of the presser foot drive cylinder 35, thereby achieving automatic compression and release of the injection molded part 1. The number of presser feet 34 can also be set to more than two, and they can be positioned at appropriate locations adjacent to the positioning support block 31 to press against appropriate areas of the injection molded part 1 that can be compressed. In other embodiments, the clamping mechanism can also adopt other existing suitable designs.

[0091] In this embodiment, see Figure 1 、 Figure 3 and Figure 10Furthermore, the insertion positioning platform 3 also includes an insertion station detector 36, which is used to detect whether there is an injection molded part 1 on the positioning support block 31, and preferably can also detect whether the injection molded part 1 is installed in place. The insertion station detector 36 is communicatively connected to the control mechanism. Before the metal handling device 7 performs the insertion action, the injection molded part 1 is first detected by the insertion station detector 36, and then the insertion is performed to avoid incorrect operation. The insertion station detector 36 can adopt an existing suitable detector, such as a photoelectric sensor, a contact sensor or a visual detector, which can realize the detection of the presence and position of the injection molded part 1. The insertion station detector 36 is preferably installed with an adjustable mechanism, which can easily adjust the position.

[0092] In this embodiment, see Figure 1 、 Figure 4 and Figure 5As a preferred design, the mold shell conveying device 4 includes a mold shell stop block 41, a mold shell vibration conveying trough 42 and a first vibrator 43. The mold shell vibration conveying trough 42 is installed on the first vibrator 43 and is driven to vibrate by the first vibrator 43. The mold shell vibration conveying trough 42 has multiple injection molded parts 1 arranged along its length direction, and an injection molded part 1 is placed in the width direction, and the injection molded part 1 and the two side walls of the mold shell vibration conveying trough 42 in the width direction are gap-fitted. In this way, when the mold shell vibration conveying trough 42 vibrates, it will output one injection molded part 1 from its output end at a time, and at the same time can limit the posture of the injection molded part 1 during the conveying process. The molded shell stop block 41 is fixedly arranged at the output end of the molded shell vibration conveying trough 42 and remains in a fixed position. The molded shell stop block 41 is provided with a molded shell stop groove cavity 411. The side of the molded shell stop groove cavity 411 includes a molded shell interface corresponding to the output end of the molded shell vibration conveying trough 42, a molded shell stop surface 4111 arranged opposite to the molded shell interface, and two molded shell limit stop surfaces 4112 arranged opposite to each other and located between the molded shell interface and the molded shell stop surface 4111. When the injection molded part 1 enters the molded shell stop groove cavity 411 and abuts against the molded shell stop surface 4111, the two ends are respectively fitted with the molded shell limit stop surfaces 4112; the molded shell to be grasped station is set in the molded shell stop groove cavity 411. The control mechanism is connected to the control of the first vibrator 43 to control the first vibrator 43 to automatically start or stop working. During operation, the first vibrator 43 drives the molded case vibration conveyor trough 42 to vibrate, gradually conveying the injection molded part 1 therein forward during vibration. During movement, the injection molded part 1 is constrained by the side walls of the molded case vibration conveyor trough 42, maintaining its posture stability and preventing the injection molded part 1 from rotating in the molded case vibration conveyor trough 42. The injection molded part 1 enters the molded case stop groove 411 of the molded case stop block 41 and stops against the molded case stop surface 4111. The injection molded part 1 at the output end of the molded case vibration conveyor trough 42 is blocked by the injection molded part 1 in front of it in the molded case stop groove 411 and no longer moves forward. The injection molded part 1 that stops in the mold shell stop groove 411 and abuts against the mold shell stop surface 4111 is located at the mold shell waiting position, waiting to be grasped, and the injection molded part 1 is constrained by the mold shell limit stop surface 4112 and the mold shell stop stop surface 4111, that is, the position of the injection molded part 1 in three directions is restricted, maintaining a stable position. Specifically in this embodiment, the injection molded part 1 moves in the mold shell vibration conveying groove 42 in a horizontal posture and enters the mold shell stop groove 411. Therefore, the width of the mold shell vibration conveying groove 42 and the width of the mold shell stop groove 411 (the distance between the two mold shell limit stop surfaces 4112) are equal to or slightly greater than the horizontal length of the injection molded part 1, and the width distance between the two mold shell limit stop surfaces 4112 is greater than or equal to the width of the mold shell vibration conveying groove 42, ensuring that the injection molded part 1 can smoothly enter the mold shell stop groove 411 from the mold shell vibration conveying groove 42.Furthermore, the stop surface 4111 of the plastic shell is set on a stop block 412 whose position can be adjusted. The position of the stop block 412 is adjusted to adjust the position of the plastic shell stop surface 4111, thereby adjusting the position of the plastic shell to be grasped.

[0093] In this embodiment, see Figure 1 、 Figure 4 and Figure 5 As a preferred design, the molded shell conveying device 4 also includes a molded shell positioning detector 45, which is used to detect whether the position of the injection molded part 1 on the molded shell to be grasped station meets the requirements, that is, to detect whether the injection molded part 1 has a misalignment problem. The molded shell positioning detector 45 is connected to the control mechanism for communication and transmits the detection signal to the control mechanism. Specifically in this embodiment, the molded shell positioning detector 45 is set at the bottom surface of the molded shell stop groove cavity 411, and a photoelectric detector can be selected. An intermediate through hole 102 is provided in the injection molded part 1. When the position of the injection molded part 1 in the molded shell stop groove cavity 411 is accurate, the molded shell positioning detector 45 is opposite to the intermediate through hole 102, and the detection light is not blocked. When the injection molded part 1 is misaligned to a certain extent in the molded shell stop groove cavity 411, the molded shell positioning detector 45 is opposite to the area around the intermediate through hole 102, and the detection light is blocked, and a corresponding detection signal is emitted, thereby judging whether the position of the injection molded part 1 meets the requirements.

[0094] See also Figure 1 、 Figure 4 and Figure 5 In this embodiment, as a preferred design, the molded case vibrating conveying trough 42 and the first vibrator 43 are mounted on a first lifting adjustment base 44, and the height position is adjusted by the first lifting adjustment base 44. Similarly, the height position of the molded case stop block 41 can also be adjusted to facilitate docking with the molded case vibrating conveying trough 42, and the molded case stop block 41 will not affect the vibration of the molded case vibrating conveying trough 42.

[0095] In this embodiment, see Figure 1 and Figure 6 As a preferred design, the molded shell handling device 5 includes a robotic arm 51 and a clamper 52 mounted on the robotic arm 51 for clamping the injection molded part 1. The clamper 52 can adopt an existing claw structure, etc., which can smoothly clamp and grasp the injection molded part 1 and can smoothly put it down. This is not limited in this application. The robotic arm 51 can also adopt an existing suitable multi-axis robotic arm 51, which can accurately drive the clamper 52 to move to the designated position. This is not limited in this application. The molded shell handling device 5 can also adopt other suitable mechanisms that can achieve the corresponding function of grabbing the injection molded part 1 and moving it. The control mechanism is connected to both the robotic arm 51 and the clamper 52 to control the automatic movement of the robotic arm 51 and the clamping action of the clamper 52.

[0096] In this embodiment, see Figure 1、 Figure 7 and Figure 8As a preferred design, the metal conveying device 6 includes a metal stop block 61, a metal vibrating conveying trough 62, and a second vibrator 63. The metal vibrating conveying trough 62 is mounted on the second vibrator 63 and driven to vibrate by the second vibrator 63. The control mechanism is connected to the second vibrator 63 and controls the second vibrator 63 to automatically start or stop the second vibrator 63. The metal vibrating conveying trough 62 has multiple metal pieces 2 arranged along its length and one metal piece 2 placed in its width. The metal piece 2 is loosely fitted with both side walls of the metal vibrating conveying trough 62 in the width direction. In this way, when the metal vibrating conveying trough 62 vibrates, it outputs one metal piece 2 at a time from its output end, while also limiting the posture of the metal piece 2 during the conveying process. The metal stop block 61 is fixedly mounted at the output end of the metal vibrating conveyor trough 62. The metal stop block 61 is provided with a metal stop groove 611. The metal stop groove 611 includes a metal interface corresponding to the output end of the metal vibrating conveyor trough 62, a metal stop surface 6111 disposed opposite the metal interface, and two metal limit surfaces 6112 disposed opposite each other and located between the metal interface and the metal stop surface 6111. When the metal part 2 enters the metal stop groove 611 and abuts against the metal stop surface 6111, its two sides respectively engage with the two metal limit surfaces 6112. The metal to-be-grabbed station is located in the metal stop groove 611. During operation, the metal vibrating conveyor trough 62 is driven to vibrate by the second vibrator 63, gradually conveying the metal part 2 therein forward. During movement, the metal part 2 is constrained by the two side walls of the metal vibrating conveyor trough 62, maintaining its stability and preventing the metal part 2 from rotating within the metal vibrating conveyor trough 62. The metal part 2 then enters the metal stop groove 611 of the metal stop block 61 and comes to rest against the metal stop surface 6111. The metal part 2 at the output end of the metal vibrating conveyor 62 is blocked by the metal part 2 in the metal stop groove 611 on the front side and comes to a stop. The metal part 2, resting in the metal stop groove 611 and against the metal stop surface 6111, is now in the metal pickup station, awaiting pickup. Furthermore, the metal part 2 is constrained by the metal limit stop surface 6112 and the metal stop surface 6111, constraining it in three directions and preventing rotation, thereby maintaining a stable position and posture. Specifically in this embodiment, the metal part 2 moves in the metal vibration conveying trough 62 in a longitudinal posture and enters the metal stop groove cavity 611. Therefore, the width of the metal vibration conveying trough 62 and the width of the metal stop groove cavity 611 (the distance between the two metal limit blocking surfaces 6112) are equal to or slightly larger than the longitudinal width of the metal part 2, and the width distance between the two metal limit blocking surfaces 6112 is greater than or equal to the width of the metal stop groove cavity 611, ensuring that the metal part 2 can smoothly enter the metal stop groove cavity 611 from the metal vibration conveying trough 62.Furthermore, the metal stop surface 6111 is provided on an adjustment block 612 , and the metal stop surface 6111 is adjusted by adjusting the position of the adjustment block 612 , thereby adjusting the metal to-be-grabbed position.

[0097] In this embodiment, see Figure 1 、 Figure 7 and Figure 8 As a preferred design, the metal conveying device 6 also includes a metal positioning detector 65. The molded shell positioning detector 45 is used to detect whether the position of the metal part 2 on the metal to be grasped station meets the requirements, that is, to detect whether the metal part 2 has a misalignment problem. The molded shell positioning detector 45 is communicatively connected to the control mechanism and transmits the detection signal to the control mechanism. Specifically in this embodiment, the metal positioning detector 65 selects a photoelectric detector, including a transmitting end and a receiving end, which are respectively arranged on opposite sides of the metal stop groove 611. When the position of the metal part 2 in the molded shell stop groove 411 is accurate, it is located between the transmitting end and the receiving end, the detection light will be blocked, and the receiving end will send out a corresponding electrical signal. When the metal part 2 does not enter the metal stop groove 611, the detection light will not be blocked. Therefore, the signal sent by the receiving end can be used to determine whether the position of the metal part 2 is accurately entered into the metal stop groove 611. The molded shell positioning detector 45 can also use other types of detectors, such as contact sensors, visual detectors, etc.

[0098] In this embodiment, see Figure 1 、 Figure 4 and Figure 5 As a preferred design, the plastic shell vibrating conveyor trough 42 and the first vibrator 43 are mounted on a second lifting adjustment base 64, and the height position is adjusted by the second lifting adjustment base 64. Similarly, the height position of the metal stop block 61 can also be adjusted to facilitate docking with the metal vibrating conveyor trough 62, and the metal stop block 61 will not affect the vibration of the plastic shell vibrating conveyor trough 42.

[0099] In this embodiment, see Figure 1 、 Figure 9 and Figure 10As a preferred design, the metal handling device 7 includes a clamping mechanism 71 for clamping the metal part 2, and a driving mechanism for driving the clamping mechanism 71 to move. The clamping mechanism 71 includes a clamping base 711, two clamping fingers 712, a linear driving portion 713, a driving block 714 and a return spring (not shown in the drawings). The two clamping fingers 712 are rotatably mounted on the clamping base 711 and arranged relative to each other. The head ends of the two clamping fingers 712 are clamping ends. When the two clamping fingers 712 rotate, the clamping ends of the two can be relatively close to or separated. The linear driving portion 713 is mounted on the clamping base 711 and is connected to the driving block 714. The driving block 714 is arranged between the tail ends of the two clamping fingers 712, and the driving block 714 and the clamping fingers 712 are in contact through a wedge surface. Specifically, one of the driving block 714 and the clamping fingers 712 can be provided with a wedge surface, or both can be provided with a wedge surface. The linear drive unit 713 drives the drive block 714 to move in a straight line, and when the drive block 714 moves toward the front end side of the clamping finger 712, it drives the two clamping fingers 712 to rotate so that the clamping ends are close together. The return spring is connected to the two clamping fingers 712, and its elastic force can drive the two clamping fingers 712 to rotate so that the clamping ends are separated. The control mechanism is connected to the control of the linear drive unit 713. The linear drive unit 713 preferably adopts a hydraulic, pneumatic or electric power cylinder, and of course other existing suitable structures can also be used. Before clamping, the piston rod of the power cylinder is in a retracted state, and the drive block 714 is close to the tail end of the clamping finger 712. Under the elastic force of the return spring, the tail ends of the two clamping fingers 712 are close to each other, and the clamping ends of the two clamping fingers 712 are now separated. When it is necessary to clamp the metal part 2, the piston rod of the power cylinder extends, driving the drive block 714 to move toward the front end of the clamping fingers 712. The wedge-shaped surface drives the two clamping fingers 712 to rotate, causing the tail ends of the two clamping fingers 712 to separate. The elastic force of the return spring increases, and the clamping ends of the two clamping fingers 712 now move closer together, thereby clamping the metal part 2. The above-mentioned clamping claw mechanism 71 is used to convert the linear displacement stroke of the drive block 714 into the rotation stroke of the two clamping fingers 712. The rotation stroke of the two clamping fingers 712 is more precise and the movement is controllable, thereby accurately controlling the pressure of the clamping claw mechanism 71 on the metal part 2, avoiding the problem of deformation of the metal part 2 caused by excessive pressure. Of course, in other embodiments, the clamping claw mechanism 71 can also adopt other existing suitable designs that can clamp the metal part 2 and can well control the clamping pressure.

[0100] In this embodiment, see Figure 1 、 Figure 9 and Figure 10As a preferred design, the driving mechanism can drive the clamping mechanism 71 to move horizontally and vertically. Specifically, it includes a horizontal driving module 73 and a vertical driving module 72 installed on the horizontal driving module 73. The clamping mechanism 71 is installed on the vertical driving module 72. The horizontal driving module 73 drives the vertical driving module 72 to move horizontally, so that the clamping mechanism 71 moves above the metal to be grasped station and above the insertion positioning platform 3. The vertical driving module 72 drives the clamping mechanism 71 to move vertically. The horizontal driving module 73 and the vertical driving module 72 can both adopt existing suitable designs, such as structures including linear slides, sliders and cylinders. The sliders are driven by the cylinders to move on the linear slides to realize the linear driving function. The control mechanism is connected to both the horizontal driving module 73 and the vertical driving module 72 to control the automatic movement of the horizontal driving module 73 and the vertical driving module 72.

[0101] In this embodiment, see Figure 1 As a preferred design, the automatic assembly equipment also includes a transmission and discharge mechanism 11, and the plastic shell handling device 5 can also grab the injection molded part 1 on the insertion positioning table 3 and transport it to the transmission and discharge mechanism 11, wherein the transmission and discharge mechanism 11 adopts a conveyor belt, and the number of conveyor belts can be set to multiple.

[0102] In this embodiment, see Figure 1 As a preferred design, the automatic assembly equipment also includes a molded shell vibrating conveyor tray 8 and a molded shell feeding mechanism 9. The molded shell vibrating conveyor tray 8 can adopt an existing suitable design, including a spiral conveyor. Many disordered injection molded parts 1 can be poured into the molded shell vibrating conveyor tray 8. Through the vibration arrangement of the molded shell vibrating conveyor tray 8, the injection molded parts 1 are arranged and moved along the spiral conveyor. During the vibration process, the injection molded parts 1 are sorted and their postures are controlled. The output port of the molded shell vibrating conveyor tray 8 is well connected with the input end of the molded shell vibrating conveying trough 42 of the molded shell conveying device 4, and does not affect the vibration of the two. After the molded shell vibrating conveyor tray 8 arranges the injection molded parts 1 therein, it is gradually output to the molded shell vibrating conveying trough 42. The molded shell feeding mechanism 9 is used to pour multiple injection molded parts 1 into the molded shell vibrating conveyor tray 8 to achieve feeding. Similarly, a metal vibrating conveyor plate 10 is also provided, which can adopt an existing suitable design and is used to continuously convey metal parts 2 to the metal vibrating conveying trough 62 of the metal conveying device 6. The working principle of the metal vibrating conveyor plate 10 is similar to that of the plastic shell vibrating conveyor plate 8. Many metal parts 2 are added therein, and through vibration sorting, the metal parts 2 are arranged and moved along the spiral conveyor path in a certain posture, and then sent to the metal vibrating conveying trough 62.

[0103] In this embodiment, the control mechanism can adopt a variety of existing suitable designs, may include structures such as a PLC controller, and may be configured with corresponding electrical components, and can realize functions such as receiving signals, data analysis and judgment, and control instruction sending. In this application, the specific design structure of the control mechanism is not limited.

[0104] As a preferred design, in this embodiment, a safety protection mechanism is also provided, including an outer partition composed of structures such as a PC transparent plate or a metal fence. The insertion positioning platform 3, the plastic shell conveying device 4, the plastic shell handling device 5 and the metal conveying device 6 are all arranged on the inner side of the outer partition to play a protective role.

[0105] The present invention also provides an automatic assembly method for an injection molded part 1 and a metal part 2, which is performed using the above-mentioned automatic assembly equipment and includes the following steps:

[0106] S1, the mold shell conveying device 4 conveys the injection molded part 1 to the mold shell waiting to be grasped station, the injection molded part 1 stops at the mold shell waiting to be grasped station, the mold shell handling device 5 grasps the injection molded part 1 on the mold shell waiting to be grasped station, and transfers it to the insertion positioning table 3, and the mold shell conveying device 4 replenishes the injection molded part 1 to the mold shell waiting to be grasped station after the injection molded part 1 on the mold shell waiting to be grasped station is taken away.

[0107] Specifically, in this embodiment, a plurality of injection molded parts 1 are arranged along the length of the molded case vibrating conveyor 42, enabling continuous feeding and loading. A control mechanism controls the first vibrator 43 to activate and vibrate the molded case vibrating conveyor 42, gradually conveying the injection molded parts 1 therein, causing one injection molded part 1 to enter the molded case stop groove 411 of the molded case stop block 41 and accurately stop at the molded case waiting position. Upon receiving a detection signal from the molded case positioning detector 45, the control mechanism controls the movement of the robotic arm 51, causing the gripper 52 to arrive at the molded case waiting position and grip the injection molded part 1. The robotic arm 51 then drives the gripper 52 and the injection molded part 1 along a predetermined motion trajectory to the insertion positioning platform 3, where the injection molded part 1 is placed on the positioning support block 31. The gripper 52 is released, and the robotic arm 51 and gripper 52 then leave the insertion positioning platform 3. When the injection molded part 1 is placed in place, it is detected by the insertion position detector 36, which sends a corresponding signal to the control mechanism. Then, the presser foot drive cylinder 35 is controlled to operate, driving the presser foot 34 to rotate and press the injection molded part 1 firmly and stably on the positioning support block 31, waiting for the insertion of the metal part 2. After the injection molded part 1 at the plastic shell pickup station is removed, the front injection molded part 1 in the plastic shell vibrating conveying trough 42 will be conveyed into the plastic shell stop groove cavity 411, thereby replenishing the injection molded part 1 at the plastic shell pickup station.

[0108] S2, the metal conveying device 6 conveys the metal part 2 to the metal to be grasped station, and the metal part 2 stops at the metal to be grasped station; the plastic shell conveying device 5 grasps the metal part 2 on the metal to be grasped station, and transfers it to the insertion positioning table 3, and inserts the metal part 2 on the injection molded part 1 on the insertion positioning table 3; after the metal part 2 on the metal to be grasped station is taken away, the plastic shell conveying device 4 replenishes the injection molded part 1 to the metal to be grasped station.

[0109] Specifically in this embodiment, a plurality of metal parts 2 are arranged along the length direction of the metal vibration conveying trough 62. The control mechanism controls the second vibrator 63 to start working, so that the metal vibration conveying trough 62 vibrates, and gradually conveys the metal parts 2 therein, so that a metal part 2 enters the metal stop groove cavity 611 of the metal stop block 61 and stops accurately at the metal to be grasped station. After receiving the detection signal of the metal positioning detector 65, the control mechanism controls the horizontal driving module 73 of the metal handling device 7 to move, driving the vertical driving module 72 and the clamping mechanism 71 thereon to move linearly in the horizontal direction, so that the clamping mechanism 71 moves to above the metal to be grasped station, and then the vertical driving module 72 drives the clamping mechanism 71 to descend, and the clamping mechanism 71 clamps the metal part 2 located on the metal to be grasped station, and then lifts the clamping mechanism 71, and then the horizontal driving module 73 drives the vertical driving module 72 and the clamping mechanism 71 thereon to move linearly in the horizontal direction, so that the clamping mechanism 71 moves to above the insertion positioning platform 3, so that the metal part 2 in the clamping mechanism 71 is aligned with the insertion position in the injection molded part 1 located on the insertion positioning platform 3, and the vertical driving module 72 drives the clamping mechanism 71 to descend, and inserts the metal part 2 in the clamping mechanism 71 into the injection molded part 1, completing the insertion action. When the metal part 2 on the metal to be grasped station is taken away, the front metal part 2 in the metal vibration conveying trough 62 will be conveyed into the metal stop groove cavity 611, so as to replenish the metal part 2 on the metal to be grasped station in time and wait for the next grasping.

[0110] After the connection is completed, the clamping mechanism 71 is released and lifted up, and the control mechanism controls the action of the clamping mechanism to release the clamping of the injection molded part 1; then the control mechanism controls the movement of the robotic arm 51, driving the clamper 52 to the insertion positioning platform 3 and grabs the injection molded part 1 with the metal part 2 connected, and moves it to a transmission and discharge mechanism 11, which delivers the product to the designated position.

[0111] After completing the plug-in assembly of one injection molded part 1 and the metal part 2, the plug-in assembly of the next injection molded part 1 and the metal part 2 is carried out. By repeating the above steps, the plug-in assembly of the injection molded part 1 and the metal part 2 is continuously carried out.

[0112] The automatic assembly equipment and method of the present invention have the following beneficial effects:

[0113] 1. It can realize the automatic plug-in assembly of the injection-molded part 1 and the metal part 2, replacing manual operation and improving work efficiency and plug-in assembly quality; 2. It can continuously realize the automatic plug-in assembly of the injection-molded part 1 and the metal part 2. During the automatic conveying and feeding process, the injection-molded part 1 and the metal part 2 can ensure stable and reliable position, convenient and accurate grasping, and can be automatically replenished; 3. It can automatically and accurately transport the injection-molded part 1 and the metal part 2, and carry out loading, plug-in, unloading and other moving processes, realizing automation and intelligence in the entire assembly process.
