[0026] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, this utility model provides an automatic cleaning and feeding pin pressing mechanism, including a frame 1, a press assembly 2, a floating press head assembly 4, and a pin cleaning and buffer module 5. The frame 1 forms a worktable 11, the press assembly 2 is fixedly connected to the worktable 11, and a press head 21 is provided at the bottom of the press assembly 2. The floating press head assembly 4 is fixedly connected below the worktable 11, and the floating press head assembly 4 includes a press head assembly 45. The press head 21 can press down on the press head assembly 45. An obliquely arranged feeding channel 4561 is formed on the press head assembly 45. The pin cleaning and buffer module 5 includes a storage chamber 51, a cylinder 52, a slider 53, a feeding port 54, a discharging connector 55, an air blowing connector 56, and a cleaning port 57. The slider 53 is placed in the storage chamber 51. The cylinder 52 is connected to the slider 53. The movement of the cylinder 52 causes the slider 53 to slide, forming a first position and a second position during the sliding process. A placement groove 531 is formed within the slider 53. When the slider 53 slides to the first position, the upper end of the placement groove 531 corresponds to the position of the feed inlet 54, and the lower end of the placement groove 531 is connected to the cleaning port 57. When the slider 53 slides to the second position, the lower end of the placement groove 531 corresponds to the position of the discharge connector 55. The air blowing connector 56 is connected to the discharge connector 55. The discharge connector 55 has a through hole 551, which is connected to the air blowing connector 56. The discharge connector 55 is connected to the feed channel 4561 of the pressure head assembly 45 (not shown in the figure) through a connecting pipe. The cylinder 52 can also be replaced by other power mechanisms, such as a motor and a lead screw.

[0027] As one example, such as Figure 1 , Figure 2 and Figure 7As shown, there are two floating pressure head assemblies 4 and two pin cleaning and buffering modules 5. The two pin cleaning and buffering modules 5 are respectively connected to the feed channels 4561 on the pressure head assemblies 45 of the two floating pressure head assemblies 4 through connecting pipes. A press switching mechanism 3 is also provided. The press switching mechanism includes a moving plate 31, a switching cylinder 32, a slide rail 33, and a fixed plate 34. The fixed plate 34 is fixedly connected to the worktable 11, the slide rail 33 is fixedly connected to the fixed plate 34, the moving plate 31 is connected to the slide rail 33, and the press assembly 2 is fixedly connected to the moving plate 31. The fixed plate 34 is connected to the movable plate 31, which has an opening through which the pressure head 21 of the press assembly 2 passes. The switching cylinder 32 is fixedly connected to the fixed plate 34 and connected to the movable plate 31. The movement of the switching cylinder 32 can drive the movable plate 31 to move. During the sliding process, the movable plate 31 forms a first position and a second position. When the movable plate 31 is in the first position and the second position, the pressure head 21 corresponds to the position of the two pressure head assemblies 45 and is above the pressure head assemblies 45. At this time, the press assembly 2 is activated, so that the pressure head 21 can press down on the pressure head assemblies 45 respectively. It should be noted that the provision of two floating pressure head assemblies 4 and two pin cleaning and buffer modules 5 in this embodiment is only a preferred solution. More floating pressure head assemblies 4 and pin cleaning and buffer modules 5 can also be provided. The number of floating pressure head assemblies 4 and pin cleaning and buffer modules 5 is the same, and they are connected by a connecting pipe. In addition, different types of storage heads 457 can be provided on each pressure head assembly 4 for storing and pressing different types of pins. Preferably, the worktable 11 is provided with an adjusting block 35, which is used to limit the position of the fixed plate 34. The press assembly 2 is prior art, and its structure will not be described in detail here. The switching cylinder can also be replaced by other force-applying mechanisms.

[0028] As one example, such as Figures 3 to 5 As shown, the floating pressure head assembly includes a connecting bracket 41, a pressure head cylinder 42, a compensation unit 43, and a pressure head assembly 45. The connecting bracket 41 is fixedly connected to the bottom of the worktable 11. The pressure head cylinder 42 is fixedly connected to the connecting bracket 41. The compensation unit 43 is connected to the movable part of the pressure head cylinder 42 and to the pressure head assembly 45. It should be noted that the pressure head cylinder 42 is used to adjust the height. If the height of the pressure head assembly 45 is suitable, the pressure head cylinder 42 can be omitted. The compensation unit 43 is existing technology and is a commercially available spare part used for fine-tuning the position in the XY directions.

[0029] As one example, such as Figure 4 and Figure 5As shown, the pressure head assembly 45 includes a pressure rod 451, an end cap 454, a guide sleeve 455, a pressure head storage chamber 456, and a storage head 457. Both the end cap 454 and the guide sleeve 455 are hollow. The top end of the guide sleeve 455 is connected to the bottom end of the end cap 454, and the top end of the pressure head storage chamber 456 is connected to the bottom end of the guide sleeve 455. A discharge channel 4562 and a feed channel 4561 are formed within the pressure head storage chamber 456. The discharge channel 4562 is vertically arranged and is connected to the end cap 454 and the guide sleeve 457. The hollow portions of the storage head 457 and the end cap 4562 are connected. The upper end of the storage head 457 is connected to the bottom of the discharge channel 4562. The pressure rod 451 is inserted into the hollow portion of the end cap 454, and the bottom of the pressure rod 451 is inserted into the discharge channel 4562. The feeding channel 4561 is obliquely arranged, and the lower end of the feeding channel 4561 is connected to the discharge channel 4562. The upper end of the feeding channel 4562 is connected to the discharge connector 56 of the pin cleaning and buffer module 5 through a connecting pipe. A spring 453 is provided between the outer peripheral wall of the pressure rod 451 and the end cap 454. The storage head 457 is provided with a feeding port and a vertical channel. The feeding port of the storage head 457 is connected to the discharge channel 4562 of the pressure head storage chamber 456, and the vertical channel is connected to the feeding port and is located below the feeding port.

[0030] Preferably, such as Figure 5 As shown, a ring of extension is formed on the pressure rod 451. The bottom of the spring 453 abuts against the guide sleeve 455, and the top of the spring 453 abuts against the extension of the pressure rod 451, so that the spring 453 gives the pressure rod 451 an upward tendency to move, which facilitates the return of the pressure rod 451 to its original position. A linear bearing 452 is provided inside the end cap 454. The linear bearing 452 is sleeved on the outer periphery of the pressure rod 451, and the linear bearing 452 is located above the extension of the pressure rod 451.

[0031] As one example, such as Figure 4 and Figure 5As shown, one end of the compensation unit 43 is connected to the movable end of the pressure head cylinder 42 via the first connecting plate 441, and the other end of the compensation unit 43 is connected to the end cover 454 and the pressure head storage chamber 456 via the second connecting plate 442, with the second connecting plate 442 fitted around the guide sleeve 455. After the pin enters from the feed channel 4561 to the discharge channel 4562, it enters the feed inlet of the storage head 457. The compensation unit 43 can be finely adjusted to drive the position of the storage head 457 to be finely adjusted. The feed inlet of the storage head 457 forms a chamfer. The feed inlet, with the position of the storage head 457 being finely adjusted, cooperates with the shape and gravity of the pin itself, so that the pin position can be straightened and fall vertically downward, facilitating the pressing of the pin. Preferably, the storage head 457 has two corresponding through holes that connect to the vertical channel of the storage head 457. A photoelectric sensor 458 is also provided, which is fixedly connected to the pressure head storage cavity 456 via a connecting bracket. The two detection points of the photoelectric sensor 458 correspond to the positions of the two through holes on the storage head 457. If the pin is aligned, it can fall into the vertical channel of the storage head 457, and this will be detected by the two detection points of the photoelectric sensor 458, indicating that the pin is aligned and can be pressed. To facilitate pin pressing, the storage head 457 has a steel ball placement port that connects to the vertical channel of the storage head 457. A steel ball 4571 is placed inside the steel ball placement port, and an O-ring 4572 is fitted onto the storage head 457, surrounding the steel ball 4571.

[0032] The working principle of this utility model is as follows: The feeder blows the pin into the feed port 54 of the pin cleaning and buffer module 5. The cleaning port 57 is connected to a vacuum suction machine, causing the pin to fall into the placement groove 531 of the slider 53 and clean it, removing dust and debris from the pin surface and the placement groove 531. Then, the cylinder 52 pushes the pin above the discharge connector 55. At this time, the air blowing connector 56 is connected to the vacuum blower, and the blown air flows out through the through hole 551 to form a negative pressure. Under the action of its own gravity, the pin slides out from the discharge connector 56. Through air blowing, the pin enters the feed channel 4561 of the press head storage chamber 456 of the press head assembly 45 via the connecting pipe, and then enters the discharge channel 4562 to the feed inlet of the storage head 457. Through the action of the compensation unit 43, the pin falls into the vertical channel of the storage head 457. When the photoelectric sensor 458 detects the pin, it indicates that the pin has fallen into the pressable position. At this time, the press switching mechanism 3 drives the press assembly 2 to move, so that the press head 21 of the press assembly 2 is above the press rod 451 of the press head assembly 45, and then the pressing work can begin. After the press assembly 2 completes the pressing work on the pin in one press head assembly 45, it can move to the other press head assembly 45 to continue the pressing work. Meanwhile, the press head assembly 45 that has just finished pressing work is refilled with pins according to the above steps, awaiting the next round of pressing work from the press assembly 2. According to actual production needs, different types of pins can be filled into the two press head assemblies 45 respectively, improving the efficiency of pin pressing.

[0033] As can be seen from the above description, this utility model is equipped with a pin cleaning and buffer module 5, which can vacuum clean the pins blown in by the material handling machine, and also serves to temporarily store and blow pins. By setting a press position switching module 3 and multiple floating press head assemblies 4, multiple floating press head assemblies 4 can be pressed, thereby realizing the pressing of different types of pins. By setting a compensation unit 43 to guide the pins, the pins can be guided to a state of axial verticality and horizontal plane by relying solely on their own kinetic energy and gravity. The photoelectric sensor 458 configured at the end of the storage head can detect when the pins reach the required state, which facilitates the pressing of the pins and improves the accuracy and efficiency of pin pressing.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
