Detailed Implementation

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," "right," "front," and "rear," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] See Figures 1 to 5 The glue sheet feeding mechanism of this utility model includes: a base frame 1, on which a pressing station 11 with an inlet and an outlet along a first direction is arranged; a first feeding mechanism 2, which spans across the base frame 1 along a second direction, and is capable of transporting thin or thick plates without glue to the pressing station 11 of the base frame 1; and a second feeding mechanism 3, which is arranged along the first direction at the inlet of the pressing station 11 of the base frame 1, for transporting thin plates with glue to the pressing station 11 and is capable of removing ping-pong paddles that have been pressed by the pressing station 11 through the outlet from the pressing station 11.

[0025] See Figure 1 , Figure 2The base frame 1 has a pressing station 11 arranged along a first direction. In the first direction, the two ends of the pressing station 11 have an inlet and an outlet respectively. A feeding conveyor line 4 is arranged at the outlet of the pressing station 11 so that the ping-pong paddle model pressed by the pressing station 11 can be fed by the feeding conveyor line 4. The first feeding mechanism 2 is used to transport the thin plate or thick plate in the ping-pong paddle substrate to the pressing station 11 along a second direction. The first feeding mechanism 2 can rotate and change the direction of the thin plate or thick plate it transports to meet the assembly requirements of the ping-pong paddle. The second feeding mechanism 3 is used to transport the thin plate with glue to the pressing station 11.

[0026] It should be noted that there are two types of thin plates. The first type of thin plate has several horizontal grooves, allowing it to bend only horizontally and not vertically. The second type of thin plate has several vertical grooves, allowing it to bend only vertically and not horizontally. By arranging the first and second types of thin plates with alternating horizontal and vertical grooves, the bending stress of each plate is perpendicular when multiple first and second types of thin plates are stacked, thereby increasing the strength of the table tennis racket. It can be understood that the first type of thin plate can be an un-glued plate and the second type of thin plate can be a glued plate, and vice versa, as long as the horizontal and vertical grooves of adjacent plates are staggered.

[0027] Specifically, during the pressing and molding of the ping-pong paddle, firstly, the first feeding mechanism 2 transports an uncoated horizontal stripe to the pressing station 11. Then, the second feeding mechanism 3 transports a glued vertical stripe to the pressing station 11 and places it above the uncoated horizontal stripe. Next, the first feeding mechanism 2 transports a thicker plate to the pressing station 11 and presses it onto the glued horizontal stripe. Then, the second feeding mechanism 3 transports the glued vertical stripe to the pressing station 11 and places it above the thicker plate. The first feeding mechanism 2 transports the horizontally ribbed sheet without adhesive to the pressing station 11 and places it on the vertically ribbed sheet with adhesive, pressing it firmly. This completes the initial pressing and molding of the ping-pong paddle. The molded ping-pong paddle is then pushed by the second feeding mechanism 3 to the unloading conveyor line 4 and sent out of the production line. This setup features a simple structure, high degree of mechanization, convenient operation, and high production efficiency. At the same time, the fully automated pressing and molding of the ping-pong paddle ensures that the molded ping-pong paddle has the advantage of high consistency and practicality.

[0028] In one or more embodiments, the first feeding mechanism 2 includes at least a gantry 21 spanning above the base frame 1 along a second direction, at least one set of two-axis linear modules 22 disposed on the gantry 21, and an adsorption structure 23 driven by the two-axis linear modules 22 for clamping thin or thick plates; the adsorption structure 23 includes at least a rotary cylinder 231 disposed on the two-axis linear modules 22 and a suction cup 232 controlled to rotate by the rotary cylinder 231.

[0029] See Figure 1 , Figure 2 The gantry frame 21 is straddling the base frame 1 along the second direction. Two sets of two-axis linear modules 22 are installed on the gantry frame 21. Each two-axis linear module 22 is connected to an adsorption structure 23. The two sets of two-axis linear modules 22 are used to transport the thin plates without adhesive on both sides of the pressing station 11 of the base frame 1 to the pressing station 11. Each set of two-axis linear modules 22 can drive the adsorption structure 23 to move along the second direction or along the vertical direction. The adsorption structure 23 includes a rotary cylinder 231 and a suction cup 232 that is controlled to rotate by the rotary cylinder 231.

[0030] Specifically, when transporting the thin plates on both sides of the base frame 1 at the pressing station 11, the two-axis linear module 22 is first driven to move along the second direction on the gantry 21 to above the thin plate. Then, the two-axis linear module 22 is used to control the adsorption structure 23 to descend so that the suction cup 232 presses against the thin plate. After the suction cup 232 is used to press the thin plate, it can be transported to the pressing station 11. It has the characteristics of simple structure and high transport efficiency, and is practical.

[0031] In one or more embodiments, the second feeding mechanism 3 includes at least a conveying structure disposed on the base frame 1 along a first direction, a clamping structure driven by the conveying structure along the first direction, and a stop structure disposed on the clamping structure and capable of vertical lifting; the conveying structure includes at least a bracket 31 disposed on the base frame 1 along the first direction and a second cylinder 32 disposed on the bracket 31 along the first direction; the clamping structure includes at least a horizontal plate 33 conveyed by the second cylinder 32 along the first direction and a gripper cylinder 34 disposed on the horizontal plate 33, wherein the gripper cylinder 34 is located above the pressing station 11; the stop structure includes at least one set of third cylinders 35 disposed on the horizontal plate 33, with the protruding shaft end of the third cylinder 35 facing the pressing station 11.

[0032] See Figures 1 to 5 The second feeding mechanism 3 is used to transport the thin plate with adhesive to the pressing station 11 and push the ping-pong paddle with adhesive and pressing completed to the unloading conveyor line 4; the second feeding mechanism 3 includes a conveying structure, a clamping structure and a stop structure.

[0033] After the sheet with adhesive is conveyed to the inlet of the pressing station 11, the gripper cylinder 34, which is mounted on the horizontal plate 33, clamps the sheet. The second cylinder 32, mounted on the bracket 31 along the first direction, drives the horizontal plate 33 to move towards the pressing station 11. When the sheet with adhesive is transported directly above the pressing station 11, the gripper cylinder 34 releases its grip on the sheet, and the sheet with adhesive falls onto the sheet without adhesive on the pressing station 11. Then, the first feeding mechanism... 2. The thick plate without adhesive is transported and pressed onto the thin plate with adhesive, and the above process is repeated to make the three plates present a structure of thin plate, glue plate, thick plate, glue plate, thin plate. After the three plates are pressed, the extension shaft end of the third cylinder 35 is extended. The second cylinder 32 is used to control the horizontal plate 33 and the third cylinder 35 to move along the first direction toward the unloading conveyor line 4. The extension shaft end of the third cylinder 35 can press against and push the pressed ping-pong paddle, thereby realizing the unloading of the ping-pong paddle.

[0034] In one or more embodiments, the base frame 1 is provided with a limiting structure for restricting the position of the thin plate and the thick plate on the pressing station 11. The limiting structure includes at least a first cylinder 51 disposed at the outlet of the pressing station 11 and a first limiting plate 52 that is vertically driven and raised above the pressing station 11 by the first cylinder 51. The limiting structure also includes two sets of second limiting plates 53 disposed on both sides of the pressing station 11 along a first direction. The position of each set of second limiting plates 53 on the pressing station 11 along a second direction is adjustable.

[0035] See Figures 1 to 5 The limiting structure includes a first cylinder 51 and a first limiting plate 52 driven to rise and fall by the first cylinder 51, and also includes two sets of second limiting plates 53 arranged on both sides of the pressing station 11. When the three types of materials need to be fed and pressed, the first cylinder 51 controls the first limiting plate 52 to extend above the outlet of the pressing station 11 to restrict the three types of materials to one end near the outlet of the pressing station 11. After the three types of materials are pressed and formed, the first cylinder 51 controls the first limiting plate 52 to move downwards. This removes the restriction on the ping-pong paddle, making it easier for the second feeding mechanism 3 to push the ping-pong paddle onto the unloading conveyor line 4. In addition, both sets of second limiting plates 53 are provided with waist-shaped holes. The second limiting plates 53 are bolted to the base frame 1 on both sides of the pressing station 11. With this setting, the position of the two second limiting plates 53 relative to the pressing station 11 can be adjusted, thereby restricting the sides of the three types of materials on the pressing station 11, and further improving the uniformity of the three types of materials after pressing and forming.

[0036] In addition, this utility model also provides a ping-pong paddle board feeding mechanism, which has the rubber board feeding mechanism in any of the above embodiments.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
