[0044] Combine the following Figure 1-Figure 5 The control method of the production equipment for manufacturing automobile parts of the present invention is described. It is understood that the vehicle structure includes plastic parts, and such automobile parts are injection molded by injection molds during production. For an assembly including multiple parts, each part needs to be injection molded separately and then assembled. However, there are problems such as cumbersome production process and high cost.

[0045] In response to the above problems, Figure 1 As shown, the control method of the production equipment for manufacturing automobile parts according to the embodiment of the present invention includes the following steps:

[0046] Get glue injection information, including glue injection material, glue injection amount, glue injection temperature, and glue injection time;

[0047] Injection molding step: starting the injection of glue, the injection mold 120 injection molds the first workpiece 121 and the second workpiece 122, and after a first preset time, the injection mold 120 switches to a mold opening state;

[0048] Assembling steps: the clamping device 110 moves to the injection mold 120, the injection mold 120 ejects the first workpiece 121 to the clamping device 110, and the clamping device 110 clamps the first workpiece 121; the injection mold 120 ejects the second workpiece 122 to the clamping device 110, and the second workpiece 122 is sleeved on the first workpiece 121 to assemble the first workpiece 121 and the second workpiece 122 to form an assembly, or the second workpiece 122 falls off from the injection mold 120;

[0049] Transfer step: The clamping device 110 moves to a position away from the injection mold 120, the injection mold 120 switches to a mold closing state, and the injection mold 120 performs glue injection again.

[0050] It is understandable that an auto part may include multiple parts. Depending on the function and force of the parts, the shape and material of each part are also different. During injection molding, each part needs to be molded separately, and then the parts are assembled to form an auto part. Before injection molding, the injection information is obtained to confirm the material, injection amount, injection temperature and injection time required for the auto part molded on the injection mold 120, so as to ensure the quality of the injection molded auto part.

[0051] In the injection molding step, the injection mold 120 is set to a mold closing state, and the injection material is injected into the injection mold 120 and fully fills the mold cavity of the injection mold 120, and the first workpiece 121 and the second workpiece 122 are injection molded. The first workpiece 121 and the second workpiece 122 are suitable for connecting to form an assembly. The first workpiece 121 can be a clamping pin, and the second workpiece 122 is a clamping seat. The second workpiece 122 is suitable for being sleeved on the first workpiece 121 to form an assembly. After injection molding, after a first preset time, the first workpiece 121 and the second workpiece 122 are cooled and formed. The injection mold 120 is switched to an open mold state to facilitate the removal of the first workpiece 121 and the second workpiece 122. In some embodiments, the injection mold 120 includes a front mold and a rear mold. When in the mold closing state, the front mold and the rear mold are in contact and connected. When in the open mold state, the front mold and the rear mold are separated to facilitate the ejection of the first workpiece 121 or the second workpiece 122.

[0052] The clamping device 110 is used to grab the first workpiece 121 and the second workpiece 122, and connect the first workpiece 121 and the second workpiece 122 to form an assembly. Specifically, the clamping device 110 moves to a position corresponding to the injection mold 120, and the injection mold 120 ejects the first workpiece 121 and the second workpiece 122, wherein the clamping device 110 is suitable for clamping the first workpiece 121, and the second workpiece 122 is suitable for being sleeved on the first workpiece 121, so that the first workpiece 121 and the second workpiece 122 are assembled to form an assembly.

[0053] During the ejection process, when the injection mold 120 ejects the first workpiece 121 and the second workpiece 122 in sequence, the first workpiece 121 is ejected onto the clamping device 110. After the clamping device 110 clamps the first workpiece 121, the injection mold 120 ejects the second workpiece 122 so that the second workpiece 122 is mounted on the first workpiece 121 to form an assembly. The first workpiece 121 and the second workpiece 122 of the assembly are both injection molded in the same batch.

[0054] When the injection mold 120 ejects the first workpiece 121 and the second workpiece 122 at the same time, after the first batch of the first workpieces 121 and the second workpieces 122 are injection molded, when the clamping device 110 moves to the injection mold 120 to clamp, the first workpiece 121 is not clamped on the clamping device 110. Therefore, when the first batch of the second workpieces 122 are produced, the injection mold 120 ejects the first batch of the second workpieces 122, and the first batch of the second workpieces 122 fall off the injection mold 120.

[0055] For example, among the first batch of first workpieces A and the first batch of second workpieces B, the clamping device 110 clamps the first batch of first workpieces A, and the first batch of second workpieces B are ejected and fall off from the injection mold 120; among the second batch of first workpieces A' and the second batch of second workpieces B', the clamping device 110 clamps the second batch of first workpieces A', and the second batch of second workpieces B' are ejected and sleeved on the first batch of first workpieces A to form an assembly, that is, the first workpiece 121 is assembled with the second workpiece 122 of the next batch to form an assembly.

[0056] After the injection molding step, the first workpiece 121 and the second workpiece 122 are removed from the injection mold 120 through the assembly step, and the first workpiece 121 and the second workpiece 122 are assembled into a combined component, forming a continuous process, saving the process of transferring the first workpiece 121 and the second workpiece 122 between various devices, simplifying the production steps, and improving efficiency. In addition, only the clamping device 110 and the injection mold 120 need to cooperate with each other to complete the demoulding and assembly of the first workpiece 121 and the second workpiece 122, reducing the required production equipment and saving production costs.

[0057] In the transfer step, the clamping device 110 moves to a position away from the injection mold 120, and transfers the assembly to a predetermined position for the next step, such as testing, weighing, and packaging the assembly, and the injection mold 120 performs the next injection of glue, etc. The clamping device 110 is moved to a position away from the injection mold 120 to avoid the clamping device 110 interfering with the movement of the injection mold 120. For example, after the front mold and the rear mold of the injection mold 120 are separated, the first workpiece 121 and the second workpiece 122 are both located on the rear mold, and the first workpiece 121 and the second workpiece 122 are both ejected from the rear mold toward one side of the front mold, and the clamping device 110 moves between the front mold and the rear mold to clamp the first workpiece 121 and the second workpiece 122; after clamping the first workpiece 121 and the second workpiece 122 to form an assembly, the clamping device 110 moves to a position deviating from the injection mold 120, the front mold and the rear mold move relative to each other to contact and connect, and the injection mold 120 switches to the mold closing state to inject glue again to injection mold the first workpiece 121 and the second workpiece 122.

[0058] According to the control method of the production equipment for manufacturing automobile parts of the embodiment of the present invention, the first workpiece 121 and the second workpiece 122 are removed from the injection mold 120 by setting an assembly step in the injection step, and the first workpiece 121 and the second workpiece 122 are assembled into a combination by ejecting the first workpiece 121 and the second workpiece 122 to the clamping device 110, so as to form a continuous process, save the process of transferring the first workpiece 121 and the second workpiece 122 between various equipments, simplify the production steps, and improve efficiency. In addition, only the clamping device 110 and the injection mold 120 need to cooperate with each other to complete the demoulding and assembly of the first workpiece 121 and the second workpiece 122, and the required production equipment is reduced, saving production costs.

[0059] According to some embodiments of the present invention, a plurality of clamping modules 112 are provided on the clamping device 110, each clamping module 112 is suitable for clamping a first workpiece 121, and the injection mold 120 ejects the first workpiece to the position of the clamping module 112, so that the clamping module 112 clamps the first workpiece 121. The plurality of clamping modules 112 are evenly and spacedly distributed along the circumferential direction of the clamping device 110, and the clamping device 110 can clamp a plurality of first workpieces 121, and the plurality of first workpieces 121 and the plurality of second workpieces 122 on the clamping device 110 are assembled to form a plurality of assemblies.

[0060] The clamping device 110 can rotate along its own axis at the first station and the second station, so that the plurality of clamping modules 112 can sequentially clamp the first workpiece 121 and the second workpiece 122. In the assembly step, when the clamping device 110 rotates to the first station, the clamping module 112 is suitable for clamping the ejected first workpiece 121; when the clamping device 110 rotates to the second station, the second workpiece 122 is ejected and installed on the first workpiece 121 to assemble and form a subassembly. For example, the first workpiece 121 is a card pin, and the second workpiece 122 is a card seat. When the clamping device 110 is located at the first station, the injection mold 120 ejects the card pin, and the clamping module 112 clamps the card pin; the clamping device 110 rotates to the second station, so that the clamping module 112 clamping the card pin is opposite to the position of the card seat, and the card pin is opposite to the connection hole on the card seat for plugging the card pin. After the injection mold 120 ejects the card seat, the card seat is sleeved on the card pin, so that the card pin and the card seat are assembled to form an assembly.

[0061] See also Figure 2 As shown, according to some embodiments of the present invention, the clamping device 110 includes a plurality of clamping units 111 stacked in a plurality of layers, the plurality of clamping units 111 are cylindrical, and each layer of the clamping unit 111 is provided with four clamping modules 112. The four clamping modules 112 are spaced and evenly distributed along the circumferential direction of the clamping unit 111. During the process of the clamping device 110 rotating from the first station to the second station, the clamping unit 111 rotates 90 degrees.

[0062] like Figure 3 As shown, taking a single clamping unit 111 as an example, four clamping modules 112 are evenly distributed on the circumference of the clamping unit 111. In the counterclockwise direction, the clamping modules 112 are the first module C1, the second module C2, the third module C3 and the fourth module C4. When performing the assembly step, the clamping device 110 moves to the injection mold 120, the clamping device 110 is in the first station, and the position of the clamping module 112 on the clamping unit 111 is as shown in FIG. Figure 3 As shown, at this time, the first module C1 is opposite to the position of the first workpiece 121, and the second module C2 is corresponding to the position of the second workpiece 122. When the injection mold 120 ejects the first workpiece 121 and the second workpiece 122 in sequence, after the first workpiece 121 is ejected, the first module C1 clamps the first workpiece 121. After the first module C1 clamps the first workpiece 121, the clamping device 110 rotates to the second station, and the clamping unit 111 rotates 90 degrees in the counterclockwise direction, so that the first module C1 and the second workpiece 122 are opposite to each other, and the injection mold 120 ejects the second workpiece 122, and the second workpiece 122 is sleeved on the first workpiece 121 on the first module C1 to form an assembly.

[0063] like Figure 4As shown, when the injection mold 120 ejects the first workpiece 121 and the second workpiece 122 at the same time, after the first workpiece 121 is ejected, the first module C1 clamps the first workpiece 121. After the second workpiece 122 is ejected, if the first workpiece 121 is clamped on the second module C2, the second workpiece 122 and the assembly on the second module C2 form a combined component, and if the first workpiece 121 is not clamped on the second module C2, the second workpiece 122 falls. Afterwards, the clamping device 110 rotates 90 degrees in the counterclockwise direction, so that the first module C1 corresponds to the position of the injection mold 120 for injection molding the second workpiece 122, and the fourth module C4 corresponds to the position of the injection mold 120 for injection molding the first workpiece 121. Afterwards, a transfer step is performed, and an injection molding step is performed. After the injection molding step, an assembly step is performed, and the clamping device 110 moves to the injection mold 120. At this time, the first module C1 is opposite to the second workpiece 122, and the fourth module C4 is opposite to the first workpiece 121. The injection mold 120 ejects the first workpiece 121 and the second workpiece 122 at the same time. After the first workpiece 121 is ejected, the fourth module C4 clamps the first workpiece 121, and after the second workpiece 122 is ejected, it is assembled with the first workpiece 121 on the first module C1 to form an assembly.

[0064] See also Figure 1 As shown, according to some embodiments of the present invention, after the transfer step, the control method further includes a grasping step: the manipulator 132 removes the assembly on the clamping device 110 and transfers it to the corresponding collecting hopper. The manipulator 132 is provided with a plurality of transfer modules, each of which corresponds to each clamping module 112, and the transfer module grasps the assembly on the corresponding clamping module 112. There are a plurality of collecting hoppers, each of which corresponds to each of the transfer modules, and the manipulator 132 transfers the assembly to the corresponding collecting hopper, so that the assemblies collected in one collecting hopper correspond to the same transfer module, clamping module 112 and injection mold 120.

[0065] In some embodiments, a conveying track is provided between the collecting hopper and the robot 132, one end of the conveying track is connected to the collecting hopper, and the other end of the conveying track corresponds to the position of the assembly on the robot 132. After the robot 132 clamps the assembly, it moves to a designated position so that the assembly is opposite to the other end of the conveying track. The robot 132 releases the assembly, and the assembly slides along the conveying track and falls into the corresponding collecting hopper.

[0066] According to some embodiments of the present invention, in the injection molding step, the injection mold 120 is suitable for simultaneously injecting N first workpieces 121 and N second workpieces 122. The injection mold 120 is provided with multiple pairs of mold cavities, each pair of mold cavities includes two mold cavities, one of which is used for injection molding the first workpiece 121, and the other is used for injection molding the second workpiece 122. In the assembly step, the N first workpieces 121 and the N second workpieces 122 are assembled to form N assemblies, each of which is marked with a corresponding code from 1 to N. In the grasping step, there are N collecting hoppers, each of which is used to collect the correspondingly coded assemblies. Thus, the operation status of the manipulator 132, the clamping device 110 and the injection mold 120 can be judged by the code of the assembly in the collecting hopper, so as to find the fault point in time and perform maintenance.

[0067] Specifically, each clamping module 112 on the clamping device 110 corresponds to a pair of mold cavities, and the clamping module 112 clamps the first workpiece 121 and the second workpiece 122 in the corresponding mold cavity to form an assembly. The transfer module on the manipulator 132 corresponds one-to-one to the clamping module 112 on the clamping device 110, and the collecting hopper corresponds one-to-one to the transfer module on the manipulator 132. Therefore, according to the corresponding relationship between the collecting hopper, the manipulator 132, the clamping device 110 and the injection mold 120, the operation of the manipulator 132, the clamping device 110 and the injection mold 120 can be judged based on the number of assemblies collected in the corresponding collecting hopper, the yield rate, etc., so as to timely discover the fault point and make adjustments.

[0068] According to some embodiments of the present invention, after the transfer step, the control method further includes a detection step: obtaining image information of the assembly on the clamping device 110, identifying the defective parts by image analysis, and obtaining the codes corresponding to the defective parts. The detection step may be provided before the grasping step. The quality of the finished product of the assembly is detected in a timely manner through the detection step, and according to the codes of the detected defective parts, in the grasping step, the manipulator 132 puts the defective parts into the defective part collection box. In addition, the staff can inspect the corresponding positions on the clamping device 110 and the injection mold 120 according to the codes corresponding to the defective parts, eliminate faults in a timely manner, and improve the stability of the operation of the production equipment for manufacturing auto parts. In some embodiments, when the number of defective parts in the same coded assembly is greater than or equal to 5 times, an alarm reminder to inspect the corresponding injection mold 120 is issued.

[0069] Specifically, Figure 1 As shown, the production equipment for manufacturing automobile parts also includes a frame 130 and a camera device 131. The clamping device 110, the manipulator 132 and the camera device 131 are all connected to the frame 130. The clamping device 110 can be moved in the front-to-back direction (such as Figure 2The clamping device 110 slides in the vertical direction (as shown) to approach the injection mold 120 or deviate from the injection mold 120. Figure 2 The photographing device 131 can move relative to the clamping device 110 along the extending direction of the clamping device 110 to take a picture of the assembly on the clamping device 110 to obtain image information of the assembly. The manipulator 132 moves in the left and right directions (such as Figure 2 The clamping device 110 can move relative to the clamping device 110 (in the direction shown in FIG. 1 ) to get closer to or away from the clamping device 110.

[0070] After the clamping device 110 moves to a position away from the injection mold 120, the camera device 131 takes a photo of the assembly on the clamping device 110 to obtain image information of the assembly. The camera device 131 can take photos in multiple sections along the length direction of the clamping device 110 to obtain clear image information of all assemblies. The production equipment for manufacturing automotive parts can be provided with a controller, and the controller is in communication connection with the manipulator 132 and the camera device 131. The camera device 131 transmits the acquired image information to the controller, and the controller can identify the image information to detect the defective products and obtain the corresponding codes of the defective products. Based on the acquired codes of the defective products, the controller controls the manipulator 132 to drop the corresponding assembly into the collection box.

[0071] According to some embodiments of the present invention, a weighing device is provided at the collecting hopper, and the weighing device is used to weigh the weight of the assembly in the collecting hopper. When the weight of the corresponding collecting hopper is less than the weight of other collecting hoppers within a preset time period, an alarm reminder is issued to inspect the corresponding position of the injection mold 120, the corresponding position of the manipulator 132, and the corresponding position of the clamping device.

[0072] In some embodiments, a counter may be provided at the collecting hopper, and the counter is used to count the number of assemblies falling into the collecting hopper. When the number of assemblies falling into the corresponding collecting hopper is less than the number of assemblies in other collecting hoppers within a preset time period, an alarm reminder is issued to inspect the corresponding position of the injection mold 120, the corresponding position of the robot 132, and the corresponding position of the clamping device.

[0073] According to some embodiments of the present invention, after the grasping step, the control method of the production equipment for manufacturing automobile parts further includes a packaging step: the conveyor belt conveys the assembly in the collecting hopper to the packaging device, and a blowing device is provided at the connection between the packaging device and the conveyor belt, and the blowing device blows the assembly into the packaging device. The collecting hopper and the packaging device are connected by a conveyor belt. When the weight of the assembly in the collecting hopper or the number of the assembly reaches a certain value, the assembly in the collecting hopper is transported to the conveyor belt, and the conveyor belt rotates to transport the assembly to the packaging device. A blowing device is provided at the connection between the packaging device and the conveyor belt, and the blowing device generates an airflow to assist the assembly to fall from the conveyor belt into the packaging device for packaging.

[0074] An embodiment is provided below to facilitate understanding of the control method of the production equipment for manufacturing automobile parts of the present invention:

[0075] The production equipment for manufacturing automobile parts obtains the injection information to determine the injection material, injection amount, injection temperature and injection time of each of the first workpiece 121 and the second workpiece 122. The injection mold 120 is set to a mold closing state, and the injection mold 120 is injected with glue based on the obtained injection information. The injection mold 120 performs the first injection molding to injection mold the first batch of the first workpiece A and the first batch of the second workpiece B. The first batch of the first workpiece A and the first batch of the second workpiece B that have been injection molded are cooled and shaped. After a first preset time, the injection mold 120 is switched to an open mold state to demold the first batch of the first workpiece A and the first batch of the second workpiece B.

[0076] See also Figure 5 As shown, the dotted lines and arrows in the figure indicate the movement direction of the corresponding parts. After the injection mold 120 is switched to the mold opening state, the clamping device 110 moves to the injection mold 120. At this time, the clamping device 110 is located at the first station, and each layer of the clamping unit 111 on the clamping device 110 corresponds to a pair of the first batch of first workpieces A and the first batch of second workpieces B. The first module C1 of the multiple clamping modules 112 on the clamping unit 111 is aligned with the position of the first batch of first workpieces A, and the second module C2 is aligned with the position of the first batch of second workpieces B. The injection mold 120 ejects the first batch of first workpieces A and the first batch of second workpieces B at the same time, and the first module C1 clamps the first batch of first workpieces A; if the second module C2 clamps the first workpiece, the first batch of second workpieces B is sleeved on the first workpiece to form an assembly, if the second module C2 does not clamp the first workpiece, the first batch of second workpieces B will naturally fall after being ejected from the injection mold 120, and a recycling box can be set under the injection mold 120 to recycle the dropped first batch of second workpieces B.

[0077] After the clamping device 110 clamps the first batch of first workpieces A, it rotates 90 degrees to the second station so that the first module C1 clamped corresponds to the position of the second workpiece 122 on the injection mold 120 for injection molding. The rotation direction can be determined according to the relative position of the first workpiece and the second workpiece 122, for example, Figure 3 In the example of FIG. 1 , the clamping device 110 is adapted to rotate in a counterclockwise direction (eg Figure 5 The first batch of second workpieces B have been assembled with the first workpieces on the second module C2 or dropped, and the first batch of first workpieces A on the first module C1 have not been assembled with the second workpieces 122 to form a combination. The clamping device 110 moves to a position away from the injection mold 120, and the injection mold 120 switches to a mold closing state to inject glue again, and repeats the injection molding steps, and the injection mold 120 performs a second injection molding to injection mold the second batch of first workpieces A' and the second batch of second workpieces B'.

[0078] After the injection molding step is completed, the clamping device 110 moves to the injection mold 120, such as Figure 5 As shown, when the clamping device 110 is in the first station, the first module C1 corresponds to the position of the second batch of second workpieces B', and the fourth module C4 corresponds to the position of the second batch of first workpieces A'. The injection mold 120 ejects the second batch of first workpieces A' and the second batch of second workpieces B', and the fourth module C4 clamps the second batch of first workpieces A', and the second batch of second workpieces B' is sleeved on the first batch of first workpieces A on the first module C1 to form an assembly. Afterwards, the clamping device 110 rotates 90 degrees to the second station, so that the fourth module C4 corresponds to the position of the second workpiece 122 on the injection mold 120 for injection molding, and the third module C3 corresponds to the position of the first workpiece on the injection mold 120 for injection molding. It can be understood that the first station and the second station are relative concepts. When performing the assembly steps twice at any time, at the first station, the corresponding relationship between the clamping module 112 on the clamping unit 111 and the first workpiece and the second workpiece 122 may be different.

[0079] After the clamping device 110 clamps the second batch of first workpieces A' and the second batch of second workpieces B', a transfer step is performed so that the injection mold 120 performs the next injection. The injection mold 120 performs the third injection molding to injection-mold the third batch of first workpieces A" and the third batch of second workpieces B". At this time, each layer of the clamping unit 111 on the clamping device 110 clamps at least one assembly. Among them, the assemblies on each layer of the clamping unit 111 have the same code.

[0080] The photographing device 131 moves relative to the clamping device 110 to photograph the assembly on the clamping device 110 to obtain image information of the assembly, identify defective parts through image analysis, and obtain the code corresponding to the defective parts. When the number of defective parts of the same coded assembly is greater than or equal to 5 times, an alarm reminder is issued to inspect the corresponding position of the injection mold 120.

[0081] The manipulator 132 moves to the holding device and removes the assembly from the clamping device 110. The manipulator 132 moves again to transfer the assembly to the corresponding collecting hopper. At the same time, the manipulator 132 puts the waste into the collection box based on the code of the waste. The weighing device weighs the assembly in the collecting hopper. After a preset time period, if the weight of the assembly in the corresponding collecting hopper is less than the weight of the assembly in other collecting hoppers, an alarm reminder is issued to inspect the corresponding position of the injection mold 120, the corresponding position of the manipulator 132, and the corresponding position of the clamping device.

[0082] When the weight of the assembly in the hopper reaches a certain value, the assembly in the hopper is transported to the conveyor belt, and the conveyor belt rotates to transport the assembly to the packaging device. The blowing device generates airflow to assist the assembly to fall from the conveyor belt into the packaging device for packaging.

[0083] After the injection mold 120 performs the third injection molding, the clamping device 110 moves to the injection mold 120, such as Figure 5 As shown, when the clamping device 110 is in the first station, the fourth module C4 corresponds to the position of the third batch of second workpieces B", and the third module C3 corresponds to the position of the third batch of first workpieces A". The injection mold 120 ejects the third batch of first workpieces A" and the third batch of second workpieces B" at the same time, and the third module C3 clamps the third batch of first workpieces A", and the third batch of second workpieces B" are sleeved on the second batch of first workpieces A' on the fourth module C4 to form an assembly. Afterwards, the clamping device 110 rotates 90 degrees to the second station, so that the third module C3 corresponds to the position of the injection mold 120 where the second workpiece is injection molded, and the second module C2 corresponds to the position of the injection mold 120 where the first workpiece is injection molded.
