[0035] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the present invention provides an intelligent assembly platform for electronic control modules, including: a mounting frame 1, at least one slide 2, an assembly fixture 3 corresponding to the slide 2, a screw locking mechanism 4, a clamp 5, a labeling machine 6 and a laser head 7.

[0038] Among them, the mounting platform 11 is provided on the mounting stand 1; the slide 2 is provided on the mounting platform 11; the assembly fixture 3 is slidably provided on the slide 2, and two positions are provided on it; the screw locking mechanism 4 is provided on the mounting stand 1 and is located above the mounting platform 11, and is used to lock the screws of the parts in one of the positions when the assembly fixture 3 slides to the set position; the clamp 5 is provided on the mounting stand 1 and is located above the mounting platform 11, and is used to press the parts in one of the positions onto the parts in the other position; the labeling machine 6 is provided on the mounting stand 1 and is located above the mounting platform 11, and is used to label the pressed products; the laser head 7 is provided on the mounting stand 1 and is located above the mounting platform 11, and is used to engrave a permanent mark on the pressed products.

[0039] When using the intelligent assembly platform for electronic control modules, the first part is placed in one of the positions in the assembly fixture 3, the second part is placed in the first part, and the third part is placed in the other position; the assembly fixture 3 is moved along the slide 2 to the set position, and the first and second parts are locked by screws using the locking screw mechanism 4; the locked first and second parts are flipped over by the clamping jaws 5 provided on the mounting stand 1, and the covers are placed on the third part for pressing; the pressed product is labeled by the labeling machine 6 provided on the mounting stand 1, and a permanent mark is engraved on the product by the laser head 7 provided on the mounting stand 1. This solution places the parts to be processed on the assembly fixture 3 that can slide on the slide 2, and installs the locking screw mechanism 4, clamping jaws 5, labeling machine 6 and laser head 7 on the mounting stand 1 above the slide 2, so that multiple workstations of placement, locking, snapping, labeling and marking are integrated into one workstation. Only one process is required to complete the assembly process of the electronic control module product, and the product structure has strong adaptability. Each unit utilizes a modular design, allowing for personalized configuration of modules and assembly fixtures based on product structural characteristics and process requirements. This adapts to product structures requiring a variety of assembly processes. Process parameters are highly controllable. All module operation data during the assembly process can be set and recorded, including screw tightening torque, press fit, and label placement. All operations are mechanized, ensuring consistent and controllable process parameters. Automated processes improve assembly quality and reduce the workload of assemblers.

[0040] In this solution, the first part is the housing, the second part is the circuit board, and the third part is the cover.

[0041] In some optional embodiments, the mounting platform 1 further includes a mounting bracket 12, which includes a support frame 121 and a slide rail 122. The support frame 121 is disposed on the mounting platform 11; the slide rail 122 is disposed within the support frame 121 and is used to mount the screw locking mechanism 4, the clamping jaw 5, the labeling machine 6, and the laser head 7, so that the screw locking mechanism 4, the clamping jaw 5, the labeling machine 6, and the laser head 7 can move laterally on the slideway 2.

[0042] In this embodiment, the screw locking mechanism 4, the clamping jaws 5, the labeling machine 6 and the laser head 7 are installed on the slide rail 122 and are located above the slide 2, so that the screw locking mechanism 4, the clamping jaws 5, the labeling machine 6 and the laser head 7 can move laterally on the slide 2. This design allows the screw locking mechanism 4, the clamping jaws 5, the labeling machine 6 and the laser head 7 to be integrated into a relatively centralized position and to be arranged to slide laterally, so that the screw locking mechanism 4, the clamping jaws 5, the labeling machine 6 and the laser head 7 do not interfere with each other when performing various workstation procedures such as placement, locking, snapping, labeling and marking.

[0043] In some optional embodiments, the slide rail 122 includes two transverse slide rails, both ends of which are connected to the support frame 121, and both transverse slide rails are provided with slide seats, and the screw locking mechanism 4, the clamping jaw 5, the labeling machine 6 and the laser head 7 are respectively arranged on the two slide seats.

[0044] In this embodiment, two transverse slide rails are arranged on the support frame 121, and both ends of the transverse slide rails are connected to the support frame 121. The two transverse slide rails are arranged in parallel, and slide seats are provided on the transverse slide rails for installing the screw locking mechanism 4, the clamping jaws 5, the labeling machine 6 and the laser head 7. Such a design can prevent the screw locking mechanism 4, the clamping jaws 5, the labeling machine 6 and the laser head 7 from interfering with each other when performing various work station procedures such as placement, locking, snapping, labeling and marking.

[0045] In some optional embodiments, the intelligent assembly platform for the electric control module includes two parallel slideways 2 that are spaced apart and located below and perpendicular to the transverse slide rail.

[0046] In this embodiment, an assembly fixture 3 is installed on each slide 2. By rationally distributing the screw locking mechanism 4, clamping jaws 5, labeling machine 6, and laser head 7 on the slides of the two transverse slides, the actuators on the two slides can be alternately operated, improving operational efficiency. In this embodiment, the labeling machine 6 is installed on one slide, while the screw locking mechanism 4, clamping jaws 5, and laser head 7 are installed on another slide.

[0047] like Figure 2 As shown, in some optional embodiments, the assembly fixture 3 is provided with a pressing claw 31 for pressing the parts placed in the assembly fixture 3.

[0048] In this embodiment, a holding claw 31 is provided between the two positions. The holding claw 31 includes a rotatable shaft and a holding plate. When the second part - the circuit board is locked to the first part - the housing by screws, the holding plate of the holding claw 31 is pressed on the housing. After the housing and the circuit board are combined, the holding plate is released, the locked first part and second part are turned over, and the cover is placed on the third part for pressing. The rotating shaft is rotated to press the holding plate of the holding claw 31.

[0049] In some optional embodiments, the electronic control module intelligent assembly station further includes an image detection mechanism 8 for detecting the label barcode and the state of the locking screws.

[0050] In this embodiment, the image detection mechanism 8 is a high-precision camera. When the second part is placed inside the first part and the first and second parts are locked together by screws using the screw locking mechanism 4, the image detection mechanism 8 can capture the barcode information on the second part, i.e., the circuit board. The barcode information is then transmitted to the labeling machine 6. The labeling machine 6 can then print a label for the assembled product based on the barcode information and affix the label to a designated location on the product housing. In addition, when the assembly fixture 3 runs along the slide 2 to the initial coordinate point, the high-precision camera takes a photo of the assembled product label, compares it with the barcode information on the circuit board, and checks the tightening of the locking screws. If the label barcode and the locking screw status are qualified, the holding claw 31 releases the part. Otherwise, the holding claw 31 remains locked and is released only after rework passes the test.

[0051] A high-precision camera is used to scan and read part barcode information and assembly information, store product identity data, and bind it to assembly process parameters such as locking torque and barcode pasting coordinates to achieve multi-dimensional data traceability.

[0052] In some optional embodiments, the assembly fixture 3 is further provided with a limiting column 32 for limiting the parts on the assembly fixture 3 .

[0053] In this embodiment, a limiting column 32 is also provided on the assembly fixture 3, which is used to limit the parts on the assembly fixture 3 to avoid displacement of the parts when tightening the screws or when the locked first and second parts are flipped and placed on the third part for pressing, thereby affecting the operation accuracy.

[0054] In some optional embodiments, a pressure sensor is provided in the bin of the assembly fixture 3 to detect whether a part is placed in the bin of the assembly fixture 3 .

[0055] In this embodiment, the intelligent assembly station of the electronic control module is also equipped with a display screen 9, which is installed on the mounting stand. When executing the assembly program, the device is first initialized, and the display screen 9 prompts "Please put in the shell and circuit board". At this time, the first part of the product - the shell is placed in the first position of the assembly fixture 3, and then the second part - the circuit board is placed in the above-mentioned shell, and the high-precision camera scans the barcode on the circuit board to record the information; at this time, the sensor in the first position senses that the first part and the second part are in place, and transmits the signal to the control software, and the display screen 9 prompts "Please put in the cover plate". At this time, the third part of the product - the cover plate is placed in the second position; the sensor in the second position senses that the third part is in place, and transmits the signal to the software, and the display screen 8 prompts "The parts are in place, please press the assembly start button".

[0056] On the other hand, the present invention further provides an intelligent assembly method for an electric control module, which is implemented using any of the above-mentioned intelligent assembly platforms for electric control modules, and comprises the following steps:

[0057] S1: Place the first part in one of the bins in the assembly fixture 3, place the second part in the first part, and place the third part in another bin.

[0058] Specifically, step S1 includes: when executing the assembly program, the device is first initialized, and the display screen 9 prompts "Please put in the shell and circuit board". At this time, the first part of the product - the shell is placed in the first position of the assembly fixture 3, and then the second part - the circuit board is placed in the above-mentioned shell, and the high-precision camera scans the barcode on the circuit board to record the information; at this time, the sensor in the first position senses that the first part and the second part are in place, and transmits the signal to the control software, and the display screen 9 prompts "Please put in the cover". At this time, the third part of the product - the cover is placed in the second position; the sensor in the second position senses that the third part is in place, and transmits the signal to the software, and the display screen 8 prompts "The parts are in place, please press the assembly start button."

[0059] S2: Move the assembly fixture 3 along the slideway 2 to a set position, and lock the first part and the second part with screws.

[0060] Specifically, according to the prompt "Parts are in place, please press the assembly start button", press the assembly start button, the assembly fixture 3 enters the specified coordinate point A along the slide 2, and the screw locking mechanism 4 automatically locks the screws of the shell and circuit board parts in the first position of the assembly fixture 3, so that the two are fastened together.

[0061] S3: After the locked first part and the second part are turned over, the cover is placed on the third part for pressing.

[0062] Specifically, the clamping jaw 5 grips and reverses the first and second component combination in the first position of the assembly fixture 3, and presses the combination with the third component - the cover plate - in the second position of the assembly fixture 3;

[0063] S4: Attach labels to the laminated products and engrave permanent logos.

[0064] Specifically, the labeling machine 6 prints out the label of the assembled product based on the barcode record information on the circuit board scanned by the high-precision camera, and sticks the label to the designated position of the product shell;

[0065] The assembly fixture 3 moves along the slide 2 to the coordinate point B, at which point the laser head 7 performs permanent marking on the designated position of the housing;

[0066] In some optional embodiments, after the permanent mark is engraved, the assembly fixture 3 is returned to the initial position, and the label barcode and the locking screw status are checked. When the label barcode and the locking screw status are qualified, the holding claw 31 releases the part; otherwise, the holding claw 31 continues to lock and is released after the rework is qualified.

[0067] In this example, a high-precision camera is used to detect label barcodes and screw locking status, scan and read part barcode information and assembly information, store product identity data, and bind it to assembly process parameters such as locking torque and barcode pasting coordinates to achieve multi-dimensional data traceability.

[0068] In summary, this solution places the parts to be processed on an assembly fixture 3 that can slide on a slide 2, and installs a screw locking mechanism 4, a clamp 5, a labeling machine 6, and a laser head 7 on the mounting stand 1 above the slide 2, so that multiple workstations such as placement, locking, snapping, labeling, and marking are integrated into one workstation. Only one process is needed to complete the assembly process of the electronic control module product, and the product structure has strong adaptability. Each unit adopts a modular design, and each unit module and assembly fixture can be personalized according to the product structure characteristics and process requirements, which can adapt to the product structure of various assembly processes; the process parameters are highly controllable. All module operation data of the assembly process can be set and recorded, such as the screw tightening torque, the degree of pressing into place, and the label pasting position. All are mechanized operations with good consistency and controllable process parameters. Automated processes can improve assembly quality and reduce the labor intensity of assemblers.
