Description

Technical Field

[0001] This invention relates to the field of terminal shaping and inspection technology, specifically to a terminal shaping and inspection device. Background Technology

[0002] During terminal manufacturing, products typically undergo multiple processes such as stamping, bending, and electroplating. Due to the release of processing stress and material deformation, terminals are prone to various minute geometric errors, including flatness deviations, gap variations, and localized warping. To ensure that terminals meet the requirements of subsequent assembly and performance, they usually need to be shaped and corrected.

[0003] In actual production, terminals are often transported and stored in the form of tape rolls. The shaping process needs to be completed simultaneously during continuous unwinding.

[0004] Currently, automated shaping equipment mainly adopts a combination of continuous unwinding and intermittent shaping to achieve automatic terminal shaping. This method relies on the precise matching of the unwinding rhythm and the shaping rhythm, but during operation, the difference in speed between the two can easily lead to accumulated errors, thus affecting the stability of the shaping process.

[0005] To mitigate the impact of accumulated errors, some technical solutions incorporate adaptive tensioning mechanisms that automatically adjust the tension of the terminal strip for compensation. However, this approach introduces additional stretching and friction, which can easily cause plating wear on electroplated terminals, affecting product quality.

[0006] Other common solutions involve setting up a buffer zone between the unwinding mechanism and the forming mechanism to absorb speed fluctuations and mitigate cycle time interference. However, the buffer zone can only alleviate, not fundamentally eliminate, the problem of error accumulation. Furthermore, as the amount of terminal strip in the buffer zone increases, the contact pressure between the terminal strip and the forming inlet rises, exacerbating friction and increasing the likelihood of coating damage.

[0007] In addition, some equipment employs intermittent unwinding combined with intermittent shaping, isolating the two actions to reduce mutual interference and improve overall operational stability. However, this method typically relies on multiple sensors and a complex control system to detect changes in the position and tension of the terminal strip in real time and dynamically adjust the unwinding action based on the monitoring results. While it offers good stability during continuous operation, the overall structure is complex and the manufacturing cost is high. Summary of the Invention

[0008] This invention provides a terminal shaping and inspection device, including an automatic unwinding mechanism, a feeding track, a feeding mechanism, a shaping mechanism, and a detection mechanism. The feeding mechanism, shaping mechanism, and detection mechanism are arranged sequentially along the feeding track. The feeding mechanism includes a dual-axis drive platform with feeding needles. The feeding needles engage with holes on the strip to allow the strip to advance intermittently. The shaping mechanism performs shaping work during the feeding intervals of the feeding mechanism. The shaping mechanism includes a linear moving platform with a shaping head and a positioning needle. The positioning needles first engage with the holes to position the strip, and then the shaping head performs the shaping work. Below the automatic unwinding mechanism is a... The system includes a limiting structure and a receiving structure. The receiving structure is positioned opposite to the feed track. The strip released by the automatic unwinding mechanism moves along the feed track after passing through the limiting structure. Under its own gravity, the strip naturally droops in the area between the limiting structure and the receiving structure and comes into contact with the receiving structure, forming a relaxed buffer zone between the receiving structure and the feed track. The lowest point of the buffer zone is lower than the contact point between the strip and the receiving structure. When the strip is not in contact with the receiving structure, the automatic unwinding mechanism starts releasing material. When the strip comes into contact with the receiving structure, the releasing stops. A detection mechanism is used to check whether the shaped terminals are qualified.

[0009] In one possible implementation, the limiting structure includes a fixed shaft on which a contact sleeve is rotatably mounted. The front and rear ends of the contact sleeve are provided with annular limiting eaves for limiting the material strip.

[0010] In one possible implementation, the receiving structure is isolated from the feed track by an insulating fixing seat. Both the feed track and the receiving structure are connected to wires and connected to the control system. The material strip is a conductor, and the three constitute a detection circuit. When the material strip is in contact with the receiving structure, the detection circuit is turned on, the control system receives a material signal, and the automatic unwinding mechanism does not work. When there is no contact, the detection circuit is turned off, the control system receives a no-material signal, and the automatic unwinding mechanism starts to unwind the material.

[0011] In one possible implementation, a pressure assembly is provided on the feed track to apply a constraint force to the feed strip, constraining the feed strip's degree of freedom in the vertical direction.

[0012] In one possible implementation, the pressing assembly includes a connecting arm equipped with a pressing bearing, the connecting arm being elastically rotatable.

[0013] In one possible implementation, the feed pin and the positioning pin do not simultaneously disengage from their respective holes.

[0014] In one possible implementation, the lower ends of both the feed pin and the positioning pin are frustoconical structures.

[0015] In one possible implementation, a guide tongue is provided at one end of the feed track near the receiving structure, and the guide tongue is inclined downward from the feed track toward the receiving structure.

[0016] The above-mentioned one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: According to the terminal shaping and inspection equipment provided by the embodiments of the present invention, the automatic unwinding mechanism unwinds in an intermittent manner, eliminating the influence of the automatic unwinding mechanism on the cycle of the shaping mechanism, improving the stability of continuous shaping work, and at the same time, combined with the synergistic cooperation of the receiving structure and the limiting structure, under the action of gravity, the automatic control of the start and stop of the automatic unwinding mechanism and the constant maintenance of the extreme value of the buffer amount are realized. Moreover, the overall structure is simple, which can effectively ensure that the automatic unwinding mechanism cooperates with the shaping mechanism to continuously, stably and efficiently carry out terminal shaping work, while eliminating the impact of accumulated errors on the long-term stable operation of the automation system and the impact on the quality of the material strip. In addition, through the synergistic cooperation of the feeding mechanism and the shaping mechanism, and by utilizing the cooperation of the feeding pin and the positioning pin with the hole, the long-term stability of the automation system is further improved.

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Please see Figure 1 and Figure 3A terminal shaping and inspection device includes a frame 1, on which two automatic shaping and inspection production lines are installed. The production lines include an automatic unwinding mechanism 2, a feeding mechanism 3, a shaping mechanism 4, an inspection mechanism 5, and a material feeding track 6. The automatic unwinding mechanism 2 is located on the left side of the material feeding track 6, and the feeding mechanism 3, the shaping mechanism 4, and the inspection mechanism 5 are arranged sequentially from left to right along the material feeding track 6. The automatic unwinding mechanism 2 intermittently releases the material strip 100. Under the feeding mechanism 3, the material strip 100 moves intermittently to the right along the material feeding track 6, passing through the shaping mechanism 4 and the detection mechanism 5 in sequence. The material strip 100 forms a relaxed buffer area with a constant strip amount between the material feeding track 6 and the automatic unwinding mechanism 2. On the one hand, it eliminates the interference of the unwinding speed on the shaping cycle, and on the other hand, it effectively avoids the adverse effects of too much or too little material strip 100 in the buffer area on the overall system operation cycle and the quality of the material strip 100. This allows the entire automation system to operate continuously, efficiently and stably. Moreover, it can accurately control the intermittent unwinding cycle of the automatic unwinding mechanism 2 without the need for multiple sets of sensors and complex control systems to monitor the terminal strip status in real time, further improving the continuous, efficient and stable operation of the overall automation system.

[0033] See Figure 1 , Figure 3 , Figure 4 and Figure 5 The material roll (not shown in the figure) is mounted on the automatic unwinding mechanism 2, and a receiving structure 7 (such as...) is provided below the automatic unwinding mechanism 2. Figure 3 As shown), the receiving structure 7 and the feeding track 6 are arranged opposite to each other. A limiting structure 8 is provided between the receiving structure 7 and the automatic unwinding mechanism 2. The material strip 100 released by the automatic unwinding mechanism 2 enters the feeding track 6 after passing through the limiting structure 8. Under the action of its own gravity, the material strip 100 naturally droops in the area between the limiting structure 8 and the receiving structure 7 and forms a relaxed buffer area between the receiving structure 7 and the feeding track 6 (e.g., ...). Figure 5As shown), the lowest point of the buffer zone is lower than the contact point between the material belt 100 and the receiving structure 7. When the material belt 100 is in contact with the receiving structure 7, the automatic unwinding mechanism 2 is in a stopped unwinding state. At this time, as the feeding mechanism 3 intermittently feeds, the amount of material belt 100 in the buffer zone gradually decreases, and the belt shape continuously changes. When the material belt 100 no longer contacts the receiving structure 7, the automatic unwinding mechanism 2 automatically starts unwinding. Subsequently, as the amount of material belt 100 in the buffer zone continuously increases, the belt shape continuously changes. When the material belt 100 contacts the receiving structure 7 again, the automatic unwinding mechanism 2 automatically stops unwinding. By continuously cycling the aforementioned process, the automatic unwinding mechanism 2 intermittently adjusts according to the actual conveying state of the material belt 100. The unwinding process eliminates the need for sensor monitoring of the material strip 100's state changes and complex control systems. It works in conjunction with the shaping mechanism 4 to perform stable and efficient automated intermittent unwinding. Through the limiting mechanism 8, the maximum and minimum values ​​of the material strip 100 in the buffer zone are locked to constant preset values. That is, each time the automatic unwinding mechanism 2 unwinds until the material strip 100 contacts the receiving structure 7, the drooping state of the material strip 100 in the buffer zone is consistent, thus the maximum value of the material strip 100 in the buffer zone is the same. Similarly, each time the feeding mechanism 3 intermittently feeds until the material strip 100 no longer contacts the receiving structure 7, the state of the material strip 100 in the buffer zone is also consistent, thus the minimum value of the material strip 100 in the buffer zone is always the same. This ensures stable time intervals for each start-stop cycle of the automatic unwinding mechanism 2. Furthermore, it effectively prevents increased friction between the material strip 100 and the left feed end of the feed track 6 due to excessive buffer volume, thus avoiding wear on the material strip 100. Overall, this effectively guarantees the long-term stability and reliability of the automated system.

[0034] See Figure 3 The receiving structure 7 is electrically isolated from the feed rail 6 and the frame 1 via an insulating mounting base 11. The insulating mounting base 11 is fixedly mounted on the frame 1, and the receiving structure 7 (made of conductive material) is fixedly mounted on the insulating mounting base 11. Both the feed rail 6 and the receiving structure 7 are connected to wires, which are connected to the control system. The material strip 100 is a conductor, forming a detection loop together with the receiving structure 7 and the feed rail 6. The specific control process is as follows: when the material strip 100 contacts the receiving structure 7, the detection loop is activated, the control system receives a material presence signal, and controls the automatic unwinding mechanism 2 to stop working; when the material strip 100 contacts the receiving structure 7, the detection loop is deactivated. The control system receives a no-material signal and controls the automatic unwinding mechanism 2 to start unwinding.

[0035] See Figure 3 and Figure 5The limiting structure 8 includes a fixed shaft 81, which is fixedly mounted on the frame 1. A contact sleeve 82 is rotatably sleeved on the fixed shaft 81. Both the front and rear ends of the contact sleeve 82 are provided with annular limiting eaves 83. During the movement of the material belt 100, it contacts the contact sleeve 82 and passes between the front and rear limiting eaves 83. The limiting eaves 83 limit the material belt 100, making the material belt 100 move stably. The rotating contact sleeve 82 can effectively reduce the friction force on the material belt 100 during the movement, thereby effectively preventing the material belt 100 from wearing.

[0036] See Figure 3 and Figure 5 A guide tongue 10 is provided at the left end of the material conveying track 6. The guide tongue 10 is inclined from right to left and downward, and the left end of the guide tongue 10 is processed into a smooth curved surface. It is used to receive and guide the material belt 100 that hangs naturally from the buffer zone from below, providing a smooth transition for the material belt 100 from a relaxed hanging state to a horizontal conveying state, further improving the stability and reliability of the system operation.

[0037] See Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 10 The feeding mechanism 3 includes a dual-axis drive platform 32 on which a feeding needle 31 is mounted. The dual-axis drive platform 32 controls the feeding needle 31 to move in both the up-down and left-right directions. The feeding needle 31, by engaging with a hole 101 on the material belt 100, drives the material belt 100 to move to the right. Figure 10 As shown, the dual-axis drive platform 32 includes a horizontal moving base 321 and a vertical moving base 322. The horizontal moving base 321 is slidably mounted on the frame 1 via a horizontal slide rail 323, and the vertical moving base 322 is slidably mounted on the horizontal moving base 321 via an upper and lower slide rail 324. The feeding needle 31 is fixedly mounted on the vertical moving base 322. Both the horizontal moving base 321 and the vertical moving base 322 are driven and controlled by cylinders. Figure 7 As shown, there are two feeding needles 31 arranged side by side, and the spacing between the feeding needles 31 is the same as the spacing between two adjacent holes 101 on the material belt 100. A complete working cycle (i.e., one feeding unit) of the feeding mechanism 3 is as follows: In the initial state: the horizontal moving seat 321 is located at the starting point on the left, and the vertical moving seat 322 moves downward, so that the two feeding needles 31 are inserted into the corresponding holes 101 on the material belt 100.

[0038] Material pulling: The vertical moving seat 322 stops moving downward, and the horizontal moving seat 321 drives the feeding needle 31 and the material belt 100 to move to the right together until they reach the right end point.

[0039] Unloading and resetting: The vertical moving seat 322 moves upward, causing the feeding needle 31 to separate from the hole 101. Then, the horizontal moving seat 321 moves to the right and returns to the starting point.

[0040] At this point, a feeding unit is complete, and feeding is carried out intermittently by continuously repeating the aforementioned steps.

[0041] See Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 11 and Figure 12 The shaping mechanism 4 includes a linear motion platform 41 on which a shaping head 42 and a positioning pin 43 are mounted. The linear motion platform 41 controls the vertical movement of the shaping head 42 and the positioning pin 43. The positioning pin 43 precisely positions the material strip 100 by engaging with the hole 101. The shaping head 42 consists of two symmetrically distributed clamping jaws that move synchronously in opposite directions to perform the clamping and shaping operation. Figure 11 As shown, the linear moving platform 41 includes a linear moving base 411 and a vertical rail 412. The vertical rail 412 is fixedly installed on the frame 1. The linear moving base 411 is slidably mounted on the vertical rail 412 and is driven to move up and down by a cylinder. Symmetrical clamping jaws are slidably mounted on the linear moving base 411 and are driven by a bidirectional cylinder to achieve synchronous opening and closing. The positioning pin 43 is located on the front side of the shaping head 42, and the installation of the positioning pin 43 does not affect the left and right movement of the clamping jaws. The function of the positioning pin 43 is to pre-insert into the hole 101 before the clamping jaws hold the terminal for shaping, to position the material strip 100. This is beneficial to improving the overall accuracy and effect, and also to improving the accuracy and stability of the intermittent conveying of the material strip 100. Figure 8 As shown, there are two positioning pins 43, which are distributed in a straight line from left to right. The spacing between the positioning pins 43 is the same as the spacing between two adjacent holes 101.

[0042] The feeding mechanism 3 and the shaping mechanism 4 work together in the following sequence to achieve continuous and efficient operation: 1. When the horizontal moving seat 321 of the feeding mechanism 3 moves to the end point and the feeding needle 31 has not completely withdrawn from the hole 101, the positioning needle 43 of the shaping mechanism begins to descend and initially enters the corresponding hole 101.

[0043] 2. As the positioning pin 43 is fully inserted into the hole 101, the feeding pin 31 is completely withdrawn from the hole 101.

[0044] 3. Subsequently, the bidirectional cylinder drives the left and right shaping heads 42 to move synchronously relative to each other, clamping and shaping the terminals.

[0045] 4. After the procedure is completed, the shaping head 42 is released, and the linear moving platform 41 moves the positioning pin 43 and the shaping head 42 upward together.

[0046] 5. Before the positioning pin 43 has completely withdrawn from the hole 101, the feeding pin 31, which has completed its reset and started to descend, has been initially inserted into the corresponding hole 101.

[0047] 6. As the feed needle 31 continues to descend and insert, the positioning needle 43 completely exits from the hole 101.

[0048] Through the precise timing coordination described above, the seamless connection between feeding and shaping actions ensures the efficient and stable operation of the entire automated system.

[0049] The lower ends of both the feeding pin 31 and the positioning pin 43 are frustoconical, facilitating their smooth insertion into the holes 101. It should be noted that the installation distance between the feeding mechanism 3 and the shaping mechanism 4 is determined by the distance between adjacent holes 101, i.e., a multiple of the distance between the holes 101. This ensures that during the intermittent rightward movement of the material strip 100, the corresponding hole 101 is positioned directly below the corresponding feeding pin 31 and positioning pin 43.

[0050] See Figure 1 , Figure 2 and Figure 12 The specific shaping areas of the terminal are the side wing portion 102 and the reinforcing rib 103 area, such as... Figure 2 As shown, during the production and processing, the gap between the side wing portion 102 and the reinforcing rib 103 may become abnormal due to the influence of the processing. By clamping the side wing portion 102 and the reinforcing rib 103 with the shaping head 42, the side wing portion 102 and the reinforcing rib 103 are brought into close contact to achieve the purpose of shaping and correction.

[0051] See Figure 4 , Figure 5 and Figure 9 A pressing assembly 9 is provided on the feed track 6 to apply a constraint force to the feed strip 100, restricting the vertical freedom of the feed strip 100. The pressing assembly 9 includes a connecting arm 92 with a pressing bearing 91 installed. The connecting arm 92 is rotatably mounted on the feed track 6, and a spiral spring (not shown in the figure) is installed between the connecting arm 92 and the feed track 6. The spiral spring applies a spring force to the connecting arm 92, so that the pressing bearing 91 applies a certain constraint force to the feed strip 100, preventing the feed strip 100 from arching or tilting upwards on the feed track 6. The bearing pressing can effectively prevent the terminals from being damaged by friction and the electroplating layer.

[0052] See Figure 4The inspection mechanism 5 uses an existing CCD inspection system to inspect the dimensions of the shaped terminals. When the terminal dimensions are not up to standard, the machine stops and alarms. In addition, an automatic winding mechanism can be set on the right side of the feeding track 6 as needed to automatically rewind the shaped and inspected strip 100. Its structure and operation are the same as the automatic unwinding mechanism 2, except that the two rotate in opposite directions. For terminals that fail the inspection, marking methods are used to mark them (such as inkjet printing, laser engraving, etc.) and they are removed in the next process.

[0053] See Figure 3 and Figure 13 The automatic unwinding mechanism 2 includes a motor 21, a mounting base 22, a connecting shaft 23, and a material tray 24. The mounting base 22 is fixedly mounted on the frame 1 via a mounting bracket. The connecting shaft 23 is rotatably mounted on the mounting base 22. The motor 21 is fixedly mounted on the back of the mounting base 22 and connected to the connecting shaft 23 to drive the connecting shaft 23 to rotate. The material tray 24 is detachably and fixedly mounted on the connecting shaft 23 and rotates with the connecting shaft 23. Figure 12 As shown, there are two material trays 24, and the material roll is installed between the two material trays 24. The two are unwound as the connecting shaft 23 rotates.

[0054] Two vertically parallel take-up shafts 25 are fixedly installed on the left side of the mounting base 22. Movable blocks 26 are slidably installed on the take-up shafts 25. Follower shafts 27 are rotatably installed on the movable blocks 26. The follower shafts 27 are rotatably installed on the movable blocks 26 and abut against the material tray 24. The rotation of the material tray 24 drives the follower shafts 27 to rotate, thereby winding up the paper strip peeled from the material belt 100 (one end of the paper strip is fixed on the follower shaft 27 and winds around it as the follower shaft 27 rotates). A fixing block 28 is detachably fixedly installed on the left end of the take-up shafts 25. A spring (not shown in the figure) is connected between the fixing block 28 and the movable block 26. A pushing force is applied to the right on the movable block 26, so that the follower shaft 27 abuts tightly against the material tray 24, thereby stably performing the paper take-up operation.
