Then, it is placed on the PIN assembly loading mechanism 5. After that, the pressing part 71 on the pressing mechanism 7 presses the pins 91 of the springs 92 together. Then, the spring plate 2 is removed and sent by the PIN assembly loading mechanism 5 to the docking position with the transfer mechanism 8. The transfer mechanism 8 removes the pressed springs 92 and pins 91 and places them on the upper cover 10 on the upper cover tray 4 on the upper cover loading mechanism 6. Then, the upper cover loading mechanism 6 sends the upper cover tray 4 to the upper and lower loading positions. The assembly of pins 91, springs 92 and upper cover 10 is completed by the machine. The manual only needs to load the spring plate 2, the pin plate 3 and the upper cover tray 4, which significantly reduces the labor intensity of the manual.

In the PIN component feeding mechanism, one layer of pins 91 and springs 92 are pressed together. When the second pushing component of one layer of the top cover feeding mechanism 6 is unloading the top cover material tray, the first pushing component of another layer can be used by the transfer mechanism 8 to send the pressed pins 91 and springs 92 to the top cover 10 on the second pushing component of the other layer, ensuring the continuity of assembly, reducing production interruption time, and significantly improving assembly efficiency. Preferably, the embodiment of this case adopts a double-layer structure.

The sliding plate 55 is connected to a third driving member 56, and the sliding direction of the sliding plate 55 is parallel to the moving direction of the first displacement plate 52. The sliding plate 55 has multiple placement positions along the moving direction, and each placement position can place one needle plate 3. The sliding distance of the sliding plate 55 is the distance between the center lines of the two farthest needle plates 3. More preferably, the third guide member 54 can be composed of a slide rail or a slider, and the third driving member 56 can be a rodless cylinder or an electric telescopic cylinder, etc., as long as it can drive the sliding plate 55 to move along the third guide member 54, and is not limited thereto. The sliding plate 55 can hold two needle plates 3, and the sliding distance of the sliding plate 55 is equal to the distance between the center lines of the two needle plates 3, which can increase the number of materials fed at one time.

[0035] Please see Figures 1 to 5 Preferably, the upper surface of the sliding plate 55 is provided with a positioning pin 57, and the lower surface of the pin drop plate 3 is provided with a corresponding pin hole 32 for positioning the pin drop plate 3 on the sliding plate 55; the pin drop plate 3 is provided with a positioning post 33 at a position avoiding the pin hole 31, and the corresponding position of the spring drop plate 2 is provided with a positioning hole 22.

The quick clamps 41 can quickly clamp and fix the upper cover tray 4 on the second displacement plate 62.

[0039] Please see Figure 1 , Figure 2 , Figure 9 , Figure 10 Preferably, the pressing mechanism 7 includes a mounting frame 72 mounted above the PIN assembly feeding mechanism 5. The mounting frame 72 is equipped with a lifting drive component 73, and a lifting plate 74 is connected to the lower end face of the lifting drive component 73. A plurality of pressing components 71 are arrayed on the lower end face of the lifting plate 74. The lifting drive component 73 can preferably be a cylinder, but is not limited thereto. Multiple guide shafts are also connected between the mounting frame 72 and the lifting plate 74, and the pressing components 71 are mold ejector pins.

[0040] Please see Figure 1 , Figure 2 , Figures 11 to 14Preferably, the transfer mechanism 8 includes a support frame 81, on which a three-axis moving assembly 82 is mounted. The end of the three-axis moving assembly 82 is provided with multiple vacuum suction cups 83. Each vacuum suction cup 83 is connected to a vacuum generator for absorbing the compressed spring 92 and pin 91. The three-axis moving assembly 82 is a commercially available XYZ three-axis moving assembly 82. The end of the three-axis moving assembly 82 is provided with a suction cup mounting plate. The mounting positions of the vacuum suction cups 83 are set on the suction cup mounting plate according to the mounting holes of the pin assembly 9 on the upper cover 10 (see...). Figure 14 This facilitates improved assembly efficiency.

[0041] The working principle of this utility model is as follows:

[0042] The pins 91 are manually poured into the pin drop plate 3. By shaking the pin drop plate 3, the pins 91 fall into their corresponding pin holes 31 by their own weight. After all the pins 91 are in their holes 31, the excess pins 91 are poured out. A spring drop plate 2 is placed on top of the pin drop plate 3, with the spring holes 21 of the spring drop plate 2 corresponding to the positions of the pins 91. The springs 92 are poured into the spring drop plate 2, and by shaking the spring drop plate 2, the springs 92 fall into their corresponding spring holes 21. After all the springs 92 are in their holes, the excess springs 92 are poured out.

[0043] The pin drop plate 3 containing the pin 91 and the spring drop plate 2 containing the spring 92 are aligned and stacked together using the positioning pin 33 and positioning hole 22, and then placed in the loading area of ​​the PIN assembly loading mechanism 5. The pin hole 32 of the pin drop plate 3 is aligned with the positioning pin 57 on the sliding plate 55. The first pushing component transfers the pin to the lower side of the pressing mechanism 7. The lifting drive component 73 of the pressing mechanism 7 drives the lifting plate 74 to move the mold ejector pin (pressing component 71) downward, pressing the spring 92 into the pin 91 to form the pin assembly 9 (e.g., ...). Figure 13 As shown in the figure, during this process, the spring 92 will deform and dislodge from the spring hole 21.

[0044] Remove the drop spring plate 2, and simultaneously place the top cover tray 4 filled with top cover 10 into the loading / unloading position of the top cover loading mechanism 6. The first pushing component pushes the drop pin plate 3 containing the pin components 9 to the area docking with the transfer mechanism 8. The second pushing component transfers the top cover tray 4 to the working area docking with the transfer mechanism 8. The vacuum suction cup 83 picks up 4 pin components 9 at a time, and the three-axis moving component 82 inserts the pin components 9 into the four holes in the top cover 10. This process is repeated to assemble 72 top covers 10. After assembly, the second pushing component and the first pushing component push the top cover tray 4 filled with finished products and the empty drop pin plate 3 out of the loading / unloading positions of the pin component loading mechanism 5 and the top cover loading mechanism 6 for manual unloading.

[0045] Because the PIN component feeding mechanism 5 and the cover feeding mechanism 6 are double-layer reciprocating structures, a new round of PIN and spring 92 pressing operations and cover 10 feeding operations can be carried out simultaneously during the assembly of cover 10, preparing for the next round of PIN component pressing and cover 10 feeding. (For example, the first push component of the upper layer is currently in the docking position with the transfer mechanism 8, while the first push component of the lower layer is in the opposite position of the pressing mechanism 7, the second push component of the upper layer is currently in the docking position with the transfer mechanism 8, and the second push component of the lower layer is currently in the loading and unloading position); Moreover, since the first push component also has a sliding plate to place two pin drop plates 3, which are driven to move by the connected third drive component 56, the two pin drop plates 3 can be docked with the pressing mechanism 7 and the transfer mechanism 8 respectively, without changing the working positions of the pressing mechanism 7 and the transfer mechanism 8. Furthermore, since the needle drop plate 3 and the spring drop plate 2 need to be manually shaken, they cannot be designed to be too large. However, the upper cover tray 4 does not need to be shaken, so it can be designed to be larger to hold more upper covers 10. Therefore, when the capacity of the upper cover tray 4 is large, two needle drop plates 3 can be placed on one sliding plate of the corresponding PIN component feeding mechanism 5. In this way, while ensuring that the number of upper covers 10 and PINs are matched, the number of times the first push component moves back and forth can be reduced.

[0046] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
