[0049] Example 1

[0050] like Figures 1 to 3As shown, this embodiment provides an automated tin dipping detection equipment 100, including a flux dipping device, a tin dipping device 2, a wire package tester 3, a product fixture 4 and a control system, the flux dipping device is used to dip the product 5 into flux; the tin dipping device 2 is used to tin the product 5; the wire package tester 3 is used to detect the product 5 after tin dipping; the product fixture 4 includes a fixture, a fixture lifting assembly and a fixture transfer assembly, the fixture is used to clamp the product 5, the fixture lifting assembly is connected to the fixture, and is used to drive the fixture to lift and lower, and then lift or lower the product 5, the fixture transfer assembly is connected to the fixture lifting assembly, and is used to drive the fixture to move back and forth between any two of the flux dipping device, the tin dipping device 2 and the wire package tester 3, so that the product 5 moves automatically, and then automatically completes the flux dipping, tin dipping and detection processes. The control system is electrically connected to at least the product fixture 4 to control the automatic opening and closing of the fixture, the automatic lifting of the fixture lifting assembly, and the automatic opening and closing of the fixture transfer assembly to control the automatic tin immersion inspection process of the product 5.

[0051] In this embodiment, the flux dipping device includes a flux container 1 for containing flux. The flux container 1 is specifically a container with an open top, which can be square or round, such as Figure 3 As shown, the flux container 1 is a square container with an open top, which is mounted on a base 9 via a bracket.

[0052] In this embodiment, Figure 3 As shown, the tin immersion device 2 includes a tin melting furnace 21, and a protective cover 22 is also configured on the top of the tin melting furnace 21 to prevent the product from falling into the furnace. After the protective cover 22 is set on the top of the tin melting furnace 21, there is still a gap between the tin melting furnace 21 and the protective cover 22 to ensure the smooth progress of the tin immersion process. Figure 3 As shown, the center of the protective cover 22 is preferably recessed into the tin melting furnace 21, and the recessed space can accommodate the product 5. The tin melting furnace 21 is an existing device, and its specific structure and tin immersion principle are not described in detail here.

[0053] In this embodiment, the clamp is preferably a pneumatic clamp, such as Figures 1 to 3 As shown, it specifically includes a clamping cylinder 41 and two clamping claws 42 located on both sides of the clamping cylinder 41. The clamping cylinder 41 is used to control the two clamping claws 42 to move away from or approach each other, thereby realizing the opening and closing of the two clamping claws 42, and further realizing the clamping or loosening of the product 5 by the pneumatic clamping claws.

[0054] In this embodiment, the clamp lifting component is preferably a lifting cylinder 43.

[0055] In this embodiment, Figures 1 to 3As shown, the fixture transplanting assembly includes a frame 44, a transverse linear module 45 and a drag chain, which is horizontally mounted on the frame 44. The flux dipping device, the tin dipping device 2 and the wire package tester 3 are all located below the transverse linear module 45, and the flux dipping device, the tin dipping device 2 and the wire package tester 3 are arranged in sequence along the moving direction of the transverse linear module 45; the lifting cylinder 43 is connected to the slider of the transverse linear module 45, and the extension and retraction direction of the piston rod of the lifting cylinder 43 is perpendicular to the transverse linear module 45. The transverse linear module 45 can drive the lifting cylinder 43 as a whole to move back and forth in a straight line between any two of the flux dipping device, the tin dipping device 2 and the wire package tester 3; the drag chain is configured on the transverse linear module 45. The drag chain is also known as the wire and cable protection drag chain. It is an existing equipment and its specific structure and working principle are not repeated here.

[0056] In this embodiment, the traverse linear module 45 is an existing device, specifically a synchronous belt linear module, a ball screw linear module, or a linear motor linear module. In this embodiment, the traverse linear module 45 is preferably a ball screw linear module equipped with a servo motor. The screw has excellent self-locking properties, which can maintain the position of the lift cylinder 43 after it moves to the corresponding position.

[0057] In this embodiment, the rack 44 is a rod-shaped structure, and is generally arranged in two groups at intervals, such as Figures 1 to 3 As shown, two sets of frames 44 are vertically mounted on the base 9, and the two ends of the transverse linear module 45 are respectively connected to the top of the two frames 44. The transverse linear module 45 and the two frames 44 together form a gantry structure, which spans above the flux dipping device, the tin dipping device 2 and the wire package testing machine 3.

[0058] In this embodiment, a loading and positioning assembly 10 is also provided. The loading and positioning assembly 10 is provided on the base 9. The loading and positioning assembly 10, the flux dipping device, the tinning device 2, and the coil tester 3 are arranged in sequence along the movement direction of the transverse linear module 45. The transverse linear module 45 and the two frames 44 form a gantry structure, which is simultaneously arranged above the loading and positioning assembly 10, the flux dipping device, the tinning device 2, and the coil tester 3. The transverse linear module 45 can drive the lifting cylinder 43 to move linearly back and forth between any two of the loading and positioning assembly 10, the flux dipping device, the tinning device 2, and the coil tester 3. The above-mentioned loading and positioning assembly 10 includes a discharge seat 101 and a product sensing sensor provided on one side of the discharge seat 101. The product sensing sensor is used to sense whether there is a product 5 placed on the discharge seat 101. If a product 5 is sensed, the entire device can continue to operate normally. If no product 5 is sensed on the discharge seat 101, the device will not continue to operate.

[0059] In this embodiment, the unloading seat 101 is preferably a circular support with positioning brackets 102 spaced apart on its periphery. When the product 5 is placed on the unloading seat 101, the positioning brackets 102 on the periphery can be used to position the product 5, ensuring that the product 5 is centered on the unloading seat 101 and that the clamp can accurately clamp the product 5 on the unloading seat 101. A product sensing sensor is preferably disposed on the positioning bracket 102. The product sensing sensor is electrically connected to the control system and can generally be a camera or infrared sensor.

[0060] In this embodiment, the control system includes an electrical control box 6, an air control box 7, an operating console, and a human-machine interface 8. The fixture transfer assembly, air control box 7, operating console, and human-machine interface 8 are all electrically connected to the electrical control box 6. The electrical control box 6 generally utilizes a PLC control system, primarily controlling the opening and closing of electrical devices such as the transverse linear module 45 within the system. The air control box 7, controlled by the electrical control box 6, primarily controls the extension and retraction of the clamping cylinder 41 and the lifting cylinder 43 within the pneumatic gripper. The operating console is equipped with an equipment start switch. The operating console can be mounted on a base plate 9, and the equipment start switch utilizes a push button structure to control the opening and closing of the entire device. Alternatively, the operating console can be mounted on the ground, and the equipment start switch utilizes a foot switch to control the opening and closing of the entire device. The operating console can also be configured with alarm buttons, pause buttons, and the like as needed.

[0061] The above-mentioned automated tin-immersion testing equipment 100 has four integrated workstations on the base 9, namely, a loading and positioning assembly 10, a flux dipping device, a tin-immersion device 2, and a wire package tester 3. After setting the corresponding parameters in the human-machine interface 8 according to the product 5 to be tested, the product 5 is manually placed on the discharge seat 101, and the equipment start switch on the operating table is pressed. The equipment will automatically complete the functions of dipping flux, dipping tin, and testing according to the preset program. After the test is completed, the product stops in the unloading area and is manually taken out. The following is a detailed description of the use process of the above-mentioned automated tin-immersion testing equipment 100, taking the product 5 as the motor rotor of a two-wheeled electric vehicle as an example:

[0062] Step 1: After manually placing the product 5 on the unloading seat 101, the equipment start switch on the operating table is pressed. The linear module 45 moves horizontally to move the lifting cylinder 43 to the top of the unloading seat 101. The lifting cylinder 43 is activated, and the pneumatic clamp descends to the position of the product 5. The clamping cylinder 41 controls the clamping claw 42 to move and clamp the product 5. The lifting cylinder 43 rises and resets to lift the product 5.

[0063] Step 2: The linear module 45 moves the pneumatic gripper holding the product 5 and the lifting cylinder 43 together to the top of the flux container 1. The lifting cylinder 43 is activated, and the pneumatic gripper descends to immerse the thread end of the product 5 into the appropriate position of the flux in the flux container 1 and stops according to the program setting. The lifting cylinder 43 rises and resets to lift the product 5.

[0064] Step 3: The linear module 45 moves the pneumatic gripper holding the product 5 and the lifting cylinder 43 together to the top of the tin melting furnace 21. The lifting cylinder 43 is activated, and the pneumatic gripper descends to immerse the thread end of the product 5 into the appropriate position in the tin melting furnace 21 and stops according to the program setting. The lifting cylinder 43 rises and resets to lift the product 5.

[0065] Step 4: The transverse linear module 45 moves the pneumatic gripper holding the product 5 and the lifting cylinder 43 together above the coil tester 3. The coil tester 3 then activates and begins testing. After testing is complete, the transverse linear module 45 or another mechanism (such as a robot) can be used to move the product 5 to the unloading position for manual removal. The coil tester 3 is a conventional technology, and its specific structure and operating principle will not be detailed here.

[0066] Repeat the above steps to carry out the automatic tin immersion detection process of product 5.

[0067] In the prior art, product flux dipping, tin dipping, and testing are all manual operations, resulting in poor product consistency, a high risk of missed product inspections, and a large amount of repetitive and unnecessary labor completed manually, resulting in cost waste and other problems. Based on this, the present embodiment proposes an automated tin dipping and testing device 100, which is an automatic flux dipping, tin dipping, and testing all-in-one machine. After the employee has finished placing the material, he only needs to press a switch (or pedal) once to automatically complete the sequential transfer of the product to the four stations of the loading and positioning component 10, the flux dipping device, the tin dipping device 2, and the wire package testing machine 3. Manual loading and unloading can automatically complete multiple processes at one time, saving the labor cost waste of repeated loading and unloading, and eliminating a series of problems such as missed inspections and poor product consistency. The beneficial effects of the automated tin dipping and testing equipment 100 of this embodiment are as follows:

[0068] 1. Using PLC control program, the servo motor in the traverse linear module is precisely controlled and the repeated positioning accuracy is high.

[0069] 2. The human-machine interface displays the operation and automatically starts the test, so that good and bad products can be clearly distinguished. At the same time, the human-machine interface parameter setting and saving are adopted, which is universal for a variety of production products and can be switched with one button, which is easy to operate.

[0070] 3. The product can be automatically transferred between the four stations of the loading and positioning component 10, the flux dipping device, the tin dipping device 2 and the wire package testing machine 3, avoiding manual repeated loading and unloading at each station, saving labor and improving work efficiency.

[0071] 4. Tin plating is uniform and the tin immersion depth can be controlled to a predetermined height to ensure the quality of the product.

[0072] 5. The equipment is semi-automatic. After the employee has finished placing the materials, he only needs to press the switch (or pedal) once to automatically transfer the products to the four stations of the loading and positioning component 10, the flux dipping device, the tin dipping device 2 and the wire package testing machine 3 in sequence. It automatically completes the three necessary processes of wire package production: flux dipping, tin dipping and testing, thereby improving the tinning efficiency and yield of the products while ensuring processing consistency.

[0073] 6. The overall structure of the equipment is compact, low cost, and occupies a small space. At the same time, the three processes of dipping flux, dipping tin, and testing are combined into one, which can reduce labor intensity, streamline the process, and save manpower.

[0074] 7. Integrating the inspection process with the tin immersion process can ensure that all necessary inspections are carried out to avoid missed inspections of products.

[0075] 8. The automated tin-immersion inspection equipment 100 can be installed via a base 9 above an existing belt line, which primarily transports products such as motor rotors or stators. Products conveyed along the belt line are intercepted by the base 9, but the belt line continues to operate beneath it. The intercepted products 5 can be manually placed on the unloading station 101 for tin-immersion inspection. This structural design allows for simultaneous integration of two production modes: automated tin-immersion inspection using the automated tin-immersion inspection equipment 100 and, if the automated tin-immersion inspection equipment 100 fails, manual production can be restored at any time.

[0076] Example 2

[0077] like Figure 4 and Figure 5 As shown, this embodiment provides an automated tin immersion detection equipment 100. On the basis of the first embodiment, a protective baffle 11 is vertically arranged on the front side of the base 9. The protective baffle 11 is located in front of the flux container 1 and the tin immersion device 2 to prevent the flux, tin liquid, etc. from splashing outward.

[0078] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
