[0045] The concept, specific structure and generated technical effects of the present application will be clearly and completely described below in combination with embodiments and drawings, so as to fully understand the purposes, features and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments, and other embodiments obtained by those skilled in the art on the basis of the embodiments of the present application without creative labor are within the protection scope of the present application. In addition, all the coupling / connection relationships involved in the patent do not mean that the components are directly connected, but that a better coupling structure can be composed by adding or reducing coupling accessories according to the specific implementation. The technical features in the present application can be combined interactively without conflict.

[0046] As shown in Figure 1 , it is a whole punching and gluing mechanism in the prior art, which comprises a bottom plate 21, a foil 11, a guide plate 22, an airflow guide assembly 23, a whole punching die 12, a glue pressing module 8, a gluing module 4, a linear driving module 3 and a foil waste box 13.

[0047] The technical solution uses a feeding mechanism (not belonging to the content of the gluing mechanism, so it is not shown in Figure 1 ) to send the foil 11 to the bottom plate 21, to the lower side of the whole punching die 12 through the guide plate 22 and the airflow guide assembly 23, to perform whole punching first, to form a row of punching holes on the foil 11, and then the glue pressing module 8 presses the end of the adhesive tape, the gluing module 4 is driven by the linear driving module 3 to paste the double-sided adhesive tape on the foil 11, and when the gluing module 4 returns, the cutting knife 61 Figure 1 (not shown in the figure) cuts off the excess foil 11, and the waste falls into the foil waste box 13.

[0048] On the one hand, the above-mentioned scheme performs whole punching on the foil by using the whole punching die, and since the length of the whole punching die increases to a certain size along with the width of the foil, it is difficult to ensure the flatness and straightness, and the punching die is damaged when the punching die does not fit with the punching bottom die during the downward punching.

[0049] On the other hand, since the punching die is separated, when punching again, the problems of accumulated error of hole number and hole distance, inaccurate positioning of individual holes, one-sided wear of the punching die, and even damage to the blade edge are caused, which increases the later use and maintenance cost.

[0050] To solve the above-mentioned technical problems, the present application provides a new gluing mechanism as follows.

[0051] A clutch type synchronous punching, gluing and cutting multifunctional gluing mechanism, as shown in Figures 2 to 6 , comprises a feeding guide module 2, a linear driving module 3 (refer to Figure 1), a gluing module 4, a punching module 5, a cutting module 6, a clutch module 7 and a pressing module 8.

[0052] The feeding guiding module 2 comprises a bottom plate 21, a guiding plate 22 and an airflow guiding assembly 23, and the foil 11 is fed between the guiding plate 22 and the airflow guiding assembly 23 to the gluing module 4 below for processing.

[0053] The gluing module 4 comprises a gluing mounting plate 41, an unwinding mechanism 42, a winding mechanism 43, a gluing proximity plate 44, a gluing roller 45 and a tape cutting assembly 46.

[0054] The punching module 5 and the cutting module 6 are both mounted on the gluing mounting plate 41, so that the linear driving module 3 only needs to drive the gluing module 4 to simultaneously drive the punching module 5 and the cutting module 6.

[0055] The punching module 5 comprises a punch pin 51, a positioning plate 52 and a driving cylinder 53, the output shaft of the driving cylinder 53 is connected with a processing table 54, the driving cylinder 53 has a first stroke and a second stroke, the distance between the bottom end of the cutter 61 and the foil 11 is less than the distance between the bottom end of the punch pin 51 and the foil 11; when the driving cylinder 53 starts the second stroke, the cutter 61 and the punch pin 51 can both contact the foil 11, which is the punching process, when the driving cylinder 53 starts the first stroke, the cutter 61 can contact and cut the foil 11 while the punch pin 51 has a certain interval with the foil 11, which is the cutting process; after the punching process, a row of punching holes are formed on the foil 11, and the cutter 61 will form a row of several incisions in advance, and then the cutter 61 will cut off the excess material in the cutting process.

[0056] The cutting module 6 comprises the cutter 61, and the punch pin 51 and the cutter 61 are both arranged on the processing table 54.

[0057] In order to realize the one-by-one punching mode, the clutch module 7 is connected below the bottom plate 21 in the same direction as the linear driving module 3.

[0058] The clutch module 7 comprises a punching bottom die 71 cooperating with the punch pin 51 for punching, a clutch guide column 72 inserted into the positioning plate 52, a clutch cylinder 73 driving the clutch guide column 72, and a punching waste box 75 arranged below the punching bottom die 71.

[0059] The clutch cylinder 73 drives the clutch guide column 72 to be inserted into the positioning plate 52, so as to realize that the clutch module 7 moves on the linear driving module 3 together with the punching module 5; the clutch cylinder 73 drives the clutch guide column 72 to be separated from the positioning plate 52, so as to realize that the clutch module 7 does not move together with the punching module 5, and thus the clutch module 7 can move on the linear driving module 3 together with the punching module 5.

[0060] The control method of the punching function of the punching module 5 and the cutting function of the cutting module 6: when the driving cylinder 53 starts the first stroke, only the cutting function is allowed, that is, the cutter 61 falls and can move left and right with the linear driving module, thereby realizing foil cutting; when the driving cylinder 53 starts the second stroke, only the punching function is allowed, and the linear driving module 3 cannot move, and after the second stroke is reset, the linear driving module 3 can move.

[0061] The specific working principle includes the following detailed procedures.

[0062] I. Gluing process. The feeding guide module 2 sends the foil 11 sent by the feeding mechanism to the lower side of the gluing module 4 through the guide plate 22 and the airflow guide assembly 23, the gluing approach plate 44 is lowered to make the end of the adhesive tape adhere to the foil 11, the glue pressing assembly presses the head of the adhesive tape, the gluing roller 45 is lowered, and then the gluing assembly adheres the double-sided adhesive tape to the foil 11 under the driving of the linear driving module 3. In this process, the gluing roller 45 continuously presses the adhesive tape and the foil 11 to ensure tight adhesion.

[0063] II. Punching process. The punching module 5 is arranged behind the gluing module 4, the linear driving module 3 is set to a stepping state, and the stepping distance (i.e. the distance between two punches) is set, the driving cylinder 53 is opened to the second stroke, the punch pin 51 is driven into the punch bottom die 71, thereby punching holes in the foil 11 at the set position, and the waste after punching falls into the punching waste box 75. The punching waste box 75 can at least accommodate the punching waste amount of one shift or one day. Repeating the above actions can form a row of punched holes on the foil 11, at this time, one punching process is completed, and the gluing module 4, the punching module 5, the cutting module 6 and the clutch module 7 will move to the other end of the linear driving module 3.

[0064] III. Cutting process. The driving cylinder 53 opens the first stroke, at this time the punch does not contact the foil 11 and the cutter 61 can fall to the lower surface of the foil 11, the linear driving module 3 reversely drives the gluing module 4, drives the cutting module 6 to move together, and then makes the cutter 61 penetrate and cut the foil 11, cuts off the excess tail of the foil 11 and falls into the foil waste box 13.

[0065] In the above three processes, the clutch cylinder 73 always drives the clutch guide column to tightly adhere to the positioning plate 52, ensuring that the clutch module 7 and the gluing module 4 are driven together with the linear driving module 3 to move left and right. In addition, more importantly, the coaxiality of the punch pin 51 and the punch bottom die 71 is ensured, so that the punch pin 51 and the punch bottom die 71 can smoothly punch at any position of the entire stroke of the linear driving module 3, that is, the relative stillness between the punch pin 51 and the punch bottom die 71 is ensured, so as to avoid the damage of the punch pin 51 caused by misalignment.

[0066] The end of the clutch guide column 72 is provided with a convex cone 74, and the positioning plate 52 is provided with a corresponding concave cone groove (not shown in the figure). The positioning plate 52 is made of hard metal material, has considerable mechanism rigidity, and has a deformation-resistant supporting bearing to offset the thrust of the clutch cylinder 73, so as to further improve the coaxiality between the punch pin 51 and the punching bottom die 71 to a precision of 0.01 mm.

[0067] After the cutting process is completed, the rubber bonding module 4 returns to the initial position, at this time the clutch cylinder 73 drives the clutch guide column 72 to retract, so that the clutch guide column 72 is separated from the positioning plate 52, and the foil 11 waste falls into the channel of the foil waste box 13; before the next punching and rubber bonding process, the clutch cylinder 73 drives the clutch guide column 72 to tightly adhere to the positioning plate 52 again.

[0068] The positional relationship between the punch pin 51 and the cutter 61 is as shown in Figure 6 The distance between the bottom end of the cutter 61 and the foil 11 is less than the distance between the bottom end of the punch pin 51 and the foil 11, the foil 11 on one side of the punch pin 51 is the processed foil 11, and the foil 11 on one side of the cutter 61 is the excess foil 11 tail after cutting.

[0069] In order to further improve the flatness of the foil 11 during punching, the punching module 5 further comprises an elastic pre-pressing plate 55, a guide column 56 connected to one end of the elastic pre-pressing plate 55 and slidably connected to the other end of the processing table 54, and a spring 57 sleeved outside the guide column 56, which synchronously presses the local foil 11 during punching, forms a flat area, and reduces the punching burr of the foil 11.

[0070] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the described embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
