A pushing mechanism for pushing the product to move horizontally is provided between the symmetrical fixing plates 8. When the pushing mechanism moves horizontally toward the position of the mounting frame 5, the support plate 10 moves horizontally away from the center position of the pushing mechanism.

[0030] See also Figure 3-Figure 4The support plate 10 is elastically connected to the inner cavity side wall of the mounting plate 9 by a spring. A symmetrical cavity 12 is provided on one side of the mounting plate 9 close to the support plate 10.

The lower end of the support plate 10 is close to the side of the rotating shaft 11 and is fitted with a driving plate 26. The driving plate 2 6 is horizontally slidably connected to the inner cavity side wall of the mounting plate 9, and the upper end of the driving plate 26 is fixedly connected to the end close to the support plate 10 with a driving rod 21, and the outer wall of the end of the driving rod 21 away from the driving plate 26 is slidably matched with the inner cavities of the first groove 16, the second groove 17, the third groove 18 and the fourth groove 19, that is, when the driving plate 26 drives the driving rod 21 to move horizontally, the driving rod 21 is slidably matched with the first groove 16, thereby driving the support plate 10 to move horizontally toward the inner cavity of the mounting plate 9, and the driving rod 2 When the support plate 10 moves relatively to the inner cavity of the second groove 17, the support plate 10 remains stationary, while the driving plate 26 continues to move, and when the driving rod 21 moves relatively to the connection between the second groove 17 and the third groove 18, the driving rod 21 moves relatively to the connection between the third groove 18 and the fourth groove 19 under the action of the elastic force, and the support plate 10 is reset under the action of the elastic force, and in the process of the driving plate 26 resetting, it drives the driving rod 21 to return to the first groove 16 and the fourth groove 19 At the connection, the upper part of the inner cavity of the No. 4 groove 19 close to the No. 1 groove 16 is vertically slidably connected with a guide block 20, the upper end of the guide block 20 is elastically connected to the top of the inner cavity of the support plate 10 through a spring, and the guide block 20 is provided with an inclined surface on the side close to the No. 4 groove 19, that is, the driving rod 21 will not be hindered when moving from the inner cavity of the No. 4 groove 19 to the inner cavity of the No. 1 groove 16, and the guide block 20 will block the driving rod 21 from moving from the inner cavity of the No. 1 groove 16 to the inner cavity of the No. 4 groove 19.

[0032] See also Figure 6A driven rod 25 is fixedly connected to the middle of one side of the ring 23 close to the driving plate 26. A driving groove 27 is provided on the side wall of the driving plate 26 to slide with the outer wall of the driven rod 25. The driving groove 27 is composed of a horizontal groove and an oblique groove. The outer wall of the driven rod 25 away from the ring 23 slides with the horizontal groove and the oblique groove. When the driven rod 25 slides in the horizontal groove, the driving rod 21 moves in the inner cavity of the first groove 16. The length of the horizontal groove is the same as the vertical distance between the two ends of the first groove 16. That is, when the driving rod 21 moves to the connection between the first groove 16 and the second groove 17, the driven rod 21 moves to the inner cavity of the first groove 16. The rod 25 also moves relatively to the connection between the horizontal groove and the inclined groove. When the driven rod 25 moves relatively in the inner cavity of the inclined groove, the driving rod 21 moves horizontally in the inner cavity of the second groove 17. In the process that the driven rod 25 cooperates with the inclined groove and drives the transmission plate 22 and the support rod 13 to move downward through the ring 23 and the connecting ring 24, the support plate 10 is retracted into the inner cavity of the mounting plate 9 and remains stationary.

The product is hindered as the support rod 13 moves downward. When the driven rod 25 moves relatively to the end of the inclined groove away from the horizontal groove, the driving rod 21 moves to the connection between the second groove 17 and the third groove 18. At this time, the support plate 10 is reset under the action of elastic force, and the upper end surface of the support plate 10 will fit with the lower end surface of the product after moving down from the top, thereby supporting the product. During the reset of the support plate 10, the transmission rack 14 will contact the driven gear 15 again to drive the transmission plate 22 and the support rod 13 to rotate into the inner cavity of the cavity 12, thereby separating from the product and passing through the support plate 1 0 moves toward the inner cavity of the mounting plate 9 and separates from the product, and during the contraction of the support plate 10, the transmission plate 22 and the support rod 13 rotate out of the inner cavity of the cavity 12, replacing the support plate 10 to support the product, and during the downward movement of the transmission plate 22 and the support rod 13, the product is driven to move downward synchronously, so that the products placed on the symmetrical support plates 10 will move downward to the adjacent support plates 10 in turn, and after the support rod 13 and the transmission plate 22 drive the product to move downward, it will rotate back into the inner cavity of the cavity 12 again, and move up to the initial position as the driving plate 26 is reset.

[0033] See also Fig. 9 and Fig.12A first push plate 28 and a symmetrical second push plate 29 are respectively arranged on both sides between the symmetrical fixed plates 8. An electric push rod (not shown in the figure) is transmission-connected to the middle of the upper end of the support seat 1. The output ends of the electric push rod are transmission-connected to the first push plate 28 and the second push plate 29 respectively (the electric push rod is also called a linear drive, which is a new type of linear actuator mainly composed of a motor push rod and a control device, etc., and is a commonly used driving device in the prior art), thereby driving the first push plate 28 and the second push plate 29 to move horizontally. The interval between the symmetrical second push plates 29 is equal to the width of the first push plate 28. A symmetrical fixing rod 30 is fixedly connected to one side of the second push plate 29 close to the fixed plate 8. A symmetrical vertical push rod 30 is fixedly connected to the middle of the lower end of the symmetrical first push plate 28. A symmetrical fixing rod 30 is fixedly connected to one side of the vertical rod close to the fixing plate 8, that is, the fixing rod 30 connected to the second push plate 29 is located at a position higher than the fixing rod 30 connected to the first push plate 28, and the symmetrical second push plate 29 is close to the mounting plate 9 located at the upper end of the raised fixing plate 8.

After the dispensing of the dispensing head 7 is completed, the second push plate 29 and the first push plate 28 are reset and move away from each other. In this process, the one-way rotating plate 40 connected to the second push plate 29 and close to the position of the dispensing head 7 will rotate toward the inner cavity of the groove, thereby not The position state of the product is affected. At this time, the product will move with the first push plate 28 in the direction away from the second push plate 29, so as to approach the position of the mounting plate 9 away from the position of the second push plate 29, and contact the symmetrical support plate 10 away from the position of the second push plate 29. In the process of the reciprocating horizontal movement of the first push plate 28, the support plate 10 close to the first push plate 28 will shrink into the inner cavity of the mounting plate 9, and the support rod 13 and the transmission plate 22 close to the first push plate 28 will also drive the glue-dispensed products to move downward to the adjacent support plate 10 in turn. By arranging two placement mechanisms with only a height difference on both sides of the fixed plate 8, the undispensed products are continuously transported to the bottom of the glue dispensing head 7 through the second push plate 29.The first push plate 28 can transfer the glue-dispensed product from the upper end of the second push plate 29 to the upper end of the first push plate 28, and transport it to the support plate 10 close to the second push plate 29. The product above the support plate 10 will continue to move down, and the un-glue-dispensed product will automatically move down to the upper end of the support plate 10 located at the bottom, so that the second push plate 29 can transport the un-glue-dispensed product to the bottom of the glue dispensing head 7, and the glue-dispensed product will also automatically detach from the uppermost support plate 10, so that the first push plate 28 can continuously transport the glue-dispensed product to the upper end of the support plate 10, thereby realizing continuous glue dispensing of the product without destroying the vacuum environment, so that the glue-dispensed product has enough time to penetrate into the surface or inside of the product, improving the glue dispensing quality of the product, and only needs to load and unload multiple products at one time after glue dispensing multiple products, reducing the number of times the vacuum is destroyed and thus improving the glue dispensing rate.

[0034] See also Figure 10-11 , one end of the fixing rod 30 away from the first push plate 28 and the second push plate 29 is slidably connected to the side wall of the fixing plate 8, and the side wall of the fixing plate 8 is provided with a first slide groove 38 that slides with the fixing rod 30.

The position of the first slide groove 38 and the second slide groove 39 near the second push plate 29 is higher than the position of the first slide groove 38 and the second slide groove 39 near the first push plate 28. The lower end of the driving plate 26 near the dispensing head 7 is fixedly connected with an extension rod 31 on one side near the dispensing head 7. The outer wall of the extension rod 31 is horizontally slidably connected to the inner cavity of the mounting plate 9. The extension rod 31 The lower end of the fixed plate 8 is vertically slidably connected with a driven block 32, and the side wall of the fixed plate 8 is provided with a moving groove 34 that slides with the driven block 32. The lower end surface of the moving groove 34 is lower than the plane where the top of the sliding rod 41 is located, that is, when the sliding rod 41 moves with the fixed rod 30, it will push the driven block 32 to move horizontally, thereby driving the driving plate 26 close to the dispensing head 7 to move horizontally through the extension rod 31, and the symmetrical driving plates 26 are connected by gear and rack transmission, that is, when the driving plate 26 close to the dispensing head 7 is close to the position of the dispensing head 7, the driving plate 26 on the other side will be driven away from the position of the dispensing head 7 through the gear and rack transmission. Gear and rack transmission is a commonly used technical means in the prior art, and the symmetrical driving plates 26 are elastically connected by springs.

The outer wall of the guide rod 33 slides with the guide groove 36 and the vertical groove 37. When the sliding rod 41 moves with the fixed rod 30, it will contact the side of the driven block 32 away from the dispensing head 7, thereby pushing the driven block 32 to move horizontally, and then drive the symmetrical driving plate 26 to move horizontally through the extension rod 31. During the horizontal movement of the driven block 32, it will drive the guide rod 33 to move horizontally in the inner cavity of the transverse groove 35. When the guide rod 33 moves to the inner cavity of the guide groove 36, the driven block 32 will rise vertically and move to the guide rod 33 When the inner cavity of the guide groove 36 is away from one end of the transverse groove 35, the driven block 32 is separated from the slide bar 41 and is no longer driven by the slide bar 41. At this time, the driving rod 21 moves to the connection between the No. 2 groove 17 and the No. 3 groove 18, and resets under the action of separation, and the symmetrical driving plate 26 will also reset under the action of elastic force, thereby driving the extension rod 31 and the driven block 32 to reset. During the resetting process, the driving plate 26 will drive the transmission plate 22 and the support rod 13 to move upward, and when the fixed rod 30 drives the slide bar 41 to reset, the slide bar 41 will approach the driven block 32 again.
