TECHNICAL FIELD

[0001] The present application relates to the technical field of assembly, in particular to a semi-automatic dispensing and shielding wire assembly integrated equipment. BACKGROUND

[0002] In the production process of die casting, it is usually necessary to carry out dispensing operation in its specific cavity, and install shielding wire or shielding cover to play the role of fixing, sealing or electromagnetic shielding. At present, there are several mainstream production methods for this process link: The first kind of pure manual operation: under this operation, the operator manually completes all steps such as dispensing, placing shielding wire and pressing. This way is low in efficiency, and the product quality highly depends on the proficiency and responsibility of the operator, and the labor cost is high. Another way is that there are some single-function dispensing machines or pressing equipment on the market, but they usually only mechanize single process, and fail to integrate dispensing, assembly and detection and other processes, so the transfer between processes still needs manual carrying and positioning, and a closed-loop production process cannot be formed.

[0003] Therefore, a semi-automatic equipment integrating precise dispensing, convenient feeding and automatic detection functions is urgently needed, which can significantly improve the operation efficiency and the consistency of product quality. SUMMARY

[0004] The present application aims to overcome the deficiencies of the prior art and provide a semi-automatic dispensing and shielding wire assembly integrated equipment, which is high in integration, easy to operate, high in assembly efficiency and good in quality, and suitable for batch production and processing.

[0008] Furthermore, the dispensing assembly includes a dispensing bracket, a spring balancer, a foldable balance arm, and a dispensing gun; the spring balancer is mounted on the top of the dispensing bracket; the foldable balance arm is disposed on the dispensing bracket and located below the spring balancer; a detachable dispensing gun is provided at the front end of the foldable balance arm; wherein, the spring force output end of the spring balancer is connected to the dispensing gun for balancing the weight of the dispensing gun; the foldable balance arm has a multi-segment hinged structure for supporting the dispensing gun and adjusting its angle. Furthermore, the foldable balance arm includes at least two relatively rotatable rotating arms, one rotating arm connected to the dispensing bracket, and the other rotating arm detachably connected to the dispensing gun; the two rotating arms are hinged together and can be folded and stored relative to each other.

[0009] Furthermore, the shielding wire feeding mechanism includes a feeding rack; the bottom of the feeding rack is provided with a fixed base; the top of the fixed base has four guide posts, and the tops of the four guide posts are connected by a pressure plate; shielding wires are stacked one on top of the four guide posts in sequence. The side of the feeding rack has two slide rails; the two slide rails are equipped with a lifting frame that is driven by a power mechanism to move up and down inside a lead screw; the lead screw is located between the two slide rails; the upper surface of the lifting frame is in contact with the bottommost shielding wire.

[0010] Furthermore, the power mechanism includes a power motor, and the transmission end of the power motor drives the lead screw to rotate via a synchronous belt.

[0011] Furthermore, the detection component includes a CCD camera that can move above the product via a three-axis motion module.

[0012] Furthermore, it also includes a docking assembly line mounted on the frame and located at the front end of the product positioning fixture, the docking assembly line being used to dock products flowing out from the previous workstation.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figures 1 to 3 This application discloses a semi-automatic dispensing and shielded wire assembly integrated device, comprising a frame 1. The frame adopts a metal frame structure to provide stable load-bearing capacity and installation reference for the device. The frame 1 includes a product positioning fixture 2, a lateral locking mechanism 3, a dispensing assembly 4, a shielded wire feeding mechanism 5, and a detection assembly 6.

[0020] See Figure 4 The product positioning fixture 2 is mounted on the frame 1. The positioning assembly 2 includes two opposing limiting strips 20 that are fixedly mounted on the frame 1 by bolts. The two limiting strips 20 are arranged in parallel relative to each other, and their opposing inner sidewalls are machined with grooves 21 that match the shape of the product. The two limiting strips are used to support and position the product to be processed.

[0021] See Figure 5 A lateral locking mechanism 3 is disposed on one side of the product positioning fixture 2 to lock the product within the product positioning fixture 2, facilitating subsequent dispensing and testing of the product. Specifically, the lateral locking mechanism 3 includes a lateral support 31 disposed within the frame, on which a lifting cylinder 32 is mounted. The extension rod of the lifting cylinder has a rotary cylinder 33. The rotary cylinder 33 is provided with a clamping block 34 that can rotate around one side of the product positioning fixture. The clamping block is driven to extend and retract via a telescopic cylinder 35, and a locking slot 22 is opened on a positioning strip located on one side of the clamping block.

[0022] During operation, when it is necessary to clamp the product located within the product positioning fixture 2, firstly, the lifting cylinder 32 descends to the appropriate position, then the rotary cylinder 33 rotates, aligning the clamping block 34 with the locking port 32 in the product positioning fixture 2. Next, the telescopic cylinder 35 drives the clamping block 34 to extend horizontally, passing through the locking port 212 and clamping the product onto the limit strip 21 on the other side. During unlocking, the lifting cylinder 32 actuates to raise the entire lateral locking mechanism 3, making room for product loading and unloading.

[0023] See Figure 7 The glue assembly 4 is disposed on the upper side of the product positioning fixture 2. The glue assembly 4 is used for manual glue dispensing, reducing the operator's workload and improving dispensing stability. The glue assembly 4 includes a glue bracket 40 mounted on the frame 1. A spring balancer 41 is mounted on the top of the glue bracket 40; a foldable balance arm 42 is mounted in the middle of the glue bracket 40. The foldable balance arm 42 includes two relatively rotatable rotating arms 420. One rotating arm 420 is connected to the glue bracket 40, and the other rotating arm 420 is detachably connected to the glue gun 43. The two rotating arms 420 are hinged together and can be folded and stored relative to each other, thereby supporting the glue gun 43 and adjusting its angle. The spring output end of the spring balancer 41 is connected to the glue gun 43 to balance its weight.

[0024] When the worker needs to use the glue gun, the upward pulling force generated by the spring balancer 41 precisely balances the weight of the glue gun 43, making it easy for the operator to move the glue gun 43, resulting in high glue dispensing efficiency and quality. The foldable balance arm 42 allows the glue gun 43 to move freely and flexibly and be precisely positioned in a large space, which facilitates practical use.

[0025] See Figures 8 to 9 The shielding wire feeding mechanism 5 shown is located on the opposite side of the product. The shielding wire feeding mechanism 5 is configured to lift the shielding wire to a fixed position, and then the shielding wire 10 is manually removed.

[0026] The shielding wire feeding mechanism 5 includes a feeding rack 50; a fixed base 51 is installed at the bottom center of the feeding rack; four guide posts 52 are vertically fixed to the top of the fixed base 51. These four guide posts 52 are arranged in a rectangle, and their top ends are connected and fixed by a pressure plate 53. The pressure plate 53 also has a handle on its top. In this way, the fixed base 51, guide posts 52, and pressure plate 53 together form a storage frame for placing the shielding rings 10. Multiple shielding rings are stacked on top of each other outside the four guide posts.

[0027] Furthermore, two parallel slide rails 55 are vertically mounted on the side of the feeding rack 50; the lifting frame 57 is slidably connected to the two slide rails 55 via a linear slider, allowing for precise vertical lifting and lowering along the slide rails 55. A lead screw 58 driven by a power mechanism 56 is located between the two slide rails 55. The power mechanism 56 includes a power motor, the conveying end of which is connected to the lead screw via a synchronous belt. When the power motor starts, it drives the lead screw to rotate. The lifting frame 57 is connected to a nut located on the lead screw 58. After the power mechanism drives the lead screw 58 to rotate forward and backward, it drives the lifting frame 57 connected to the nut to perform precise vertical linear motion. The upper surface of the lifting frame 57 contacts the bottommost shielding wire 10, so that when the lifting frame moves upward, it can drive the entire shielding wire 10 to move up and down.

[0028] During operation: The power mechanism 56 drives the lifting frame 57 to rise. The lifting frame 57 pushes the entire shielded wire 10 upward from the bottom, so that the topmost shielded wire reaches the preset picking position, which is a height that is convenient for the operator to grab. When the topmost shielded wire 10 is removed, the control system receives a signal and immediately sends a command to the power mechanism 56. The power mechanism 56 drives the lead screw 58 to rotate by a predetermined angle, equivalent to the thickness of a single shielded wire, thereby driving the lifting frame 57 to rise precisely one position. The lifting frame 57 moves the entire shielded wire upward, making it convenient for the operator to grab the next shielded wire 10.

[0029] See Figure 6 The detection component 6 includes a CCD camera 61 that can move in three directions above the product via a three-axis moving module 60. After manual assembly is completed, the control system instructs the three-axis moving module 60 to move the CCD camera 61 directly above the product. The CCD camera 61 acquires the image after assembly and uses an image processing algorithm to determine whether the shielding wire is installed correctly.

[0030] Furthermore, the frame 1 is also equipped with a docking production line 7, which is installed at the front end of the product positioning fixture 2 and is used to dock products flowing out from the previous station to achieve docking with other stations.

[0031] Furthermore, the frame 1 is equipped with a control panel 8 for controlling this integrated device. The control panel 8, which integrates a PLC or industrial computer, is mounted on the frame 1. The control panel 8 is connected to relevant devices of this device, coordinates the sequential actions of various mechanisms, and makes judgments and indications of pass or fail based on the test results.

[0032] The work process is as follows: 1. The product is transported from the previous station to the front end of the equipment via the docking assembly line 7. The operator places the product into the product positioning fixture 2 and performs initial positioning of the product through the grooves of the two limit bars 21.

[0033] 2. The lifting cylinder 32 in the lateral locking mechanism 3 descends, the rotating cylinder 33 drives the pressing block 34 to rotate and align with the locking port on the product positioning fixture 2, and the telescopic cylinder pushes the pressing block to extend, pressing the product into the product positioning fixture 2.

[0034] 3. After the product is locked, the operator uses the dispensing assembly to dispense glue. The glue gun is balanced by a spring balancer, allowing the operator to easily move the glue gun and adjust the angle using the foldable balance arm, so as to conveniently and accurately inject the glue into the corresponding holes of the product.

[0035] 4. After the dispensing is completed, the operator takes the top shielding wire from the shielding wire feeding mechanism 5. The power mechanism 56 in the shielding wire feeding mechanism 5 drives the lead screw 58 to rotate at a predetermined angle, which drives the lifting frame 57 to move the entire shielding wire 10 upward, making it easier for the operator to grab the next shielding wire 10.

[0036] 5. After assembly, the detection component 6 moves the CCD camera above the product via the three-axis moving module to take pictures and collect images. The control system automatically determines whether the shielding wire is assembled in place through the image processing algorithm and displays a qualified or unqualified signal.

[0037] 6. After the test is completed, all components are reset. The operator removes the product according to the test results and places it in the qualified or defective product area, and then begins the next work cycle.

[0038] In summary, the semi-automatic dispensing and shielding wire assembly integrated equipment of the present invention integrates dispensing, assembly and testing functions into one station, reducing the transfer and waiting time between processes, realizing continuous operation, reducing human error, improving product consistency and yield, reducing labor costs, and is suitable for mass production.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
