Description

Technical Field

[0001] The utility model relates to the technical field of bonding and compounding, in particular to a bonding device for automatically conveying EPDM films. Background Art

[0002] As is known to all, EPDM membrane is a high-performance rubber material. The EPDM membrane bonding process is as follows: the EPDM membrane is separated into a peeling film and an EPDM film. After the product to be bonded (i.e., the sealing strip) is placed in the collision mold, the sealing strip is bonded to the EPDM film through the collision mold. Then, the collision mold starts the mold closing action to bond the sealing strip to the EPDM film, thereby realizing the bonding operation between the sealing strip and the EPDM film.

[0003] For example, the patent with the announcement number CN220742176U and the announcement date of April 9, 2024, and the name of the patent is "Automated bonding equipment for thermally reducing tackiness of PO protective film". This patent relates to the field of automation technology and discloses an automated bonding equipment for thermally reducing tackiness of PO protective film. The automated bonding equipment for thermally reducing tackiness of PO protective film includes a frame, a vertical motion screw, a front and back motion screw, a transverse motion screw, and a storage platform. The top of the frame is equipped with a vertical motion screw, and the bottom of the frame is equipped with a front and back motion screw, a transverse motion screw, and a storage platform in sequence. The bottom end of the vertical motion screw is equipped with a flexible heater, and the upper part of the flexible heater is equipped with a hot air blower. The automated bonding equipment for thermally reducing tackiness of PO protective film, through the coordinated use of a flexible heater, a heating unit, a heater housing, a hot air blower, a vertical motion screw, a front and back motion screw, and a transverse motion screw, can achieve the effect of bonding uneven surfaces, improving bonding efficiency, and improving bonding quality.

Most of the existing technologies require staff to recycle the peeling film, but the staff does not completely rewind the peeling film, resulting in a certain amount of waste of the peeling film.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 3As shown, an embodiment of the present invention provides an automatic EPDM film bonding device, comprising a carrier frame 1, on which a recovery roll 3, a feed roll 2, a separation mechanism, a traction mechanism and two collision mechanisms are provided. The EPDM film on the feed roll is separated into an EPDM film and a peeling film 5 by the separation mechanism. The peeling film 5 is recovered and wound by the recovery roll 3. The EPDM film is pulled linearly by the traction mechanism. The two collision mechanisms respectively clamp the sealing strip and collide with the opposite sides of the EPDM film to complete the bonding process.

[0025] Specifically, the carrier 1 is a plate member used to support parts such as the recovery roll 3, the feed roll 2, the separation mechanism, the traction mechanism and two collision mechanisms. The carrier 1 is provided with a first driving member 4, the output end of the first driving member 4 is connected to the feed roll 2, the recovery roll 3 is used to reel in the peeling film 5, the traction mechanism includes a limit rod 8, a through slot 6 is provided in the middle of the carrier 1, and a straight plate 7 is provided on each side of the through slot 6 at the bottom end of the carrier 1. Two limit rods 8 are symmetrically provided between the two straight plates 7, and a sliding block 9 is slidably installed on the two limit rods 8. One of the straight plates 7 is provided with a rodless cylinder 10, the output end of the rodless cylinder 10 is connected to the sliding block 9; the traction mechanism also includes a first bidirectional cylinder 11, a first bidirectional cylinder 11 is provided on the sliding block 9, and the two output ends of the first bidirectional cylinder 11 are respectively connected to a clamping rod 12, and the feed roll 2 is rotatably provided on the carrier 1. The unwinding of the feed roll 2 can be pulled by a staff member, or an active motor can be provided on the carrier 1 to drive the feed roll 2 to rotate; the separation mechanism includes a first guide roller 13 and a second guide roller 14, and the carrier 1 is rotatably provided with a first guide roller 13 for guiding the EPDM film;A second guide roller 14 for guiding the stripping film 5 is rotatably provided on the carrier 1. When the EPDM film needs to be bonded, the staff opens the EPDM film and separates the EPDM film into the EPDM film and the stripping film 5. Then the staff passes the end of the stripping film 5 between the first guide roller 13 and the second guide roller 14, and then winds the stripping film 5 on the recovery roll 3, so that the second guide roller 14 guides the stripping film 5. The staff then pulls the end of the EPDM film between the first guide roller 13 and the second guide roller 14 until the EPDM film is pulled to the part between the two clamping rods 12, guides the EPDM film through the first guide roller 13, separates the EPDM film and the stripping film 5 through the first guide roller 13 and the second guide roller 14, starts the first bidirectional cylinder 11 and simultaneously drives the two clamping rods 12 to move toward one end close to each other, so that the two clamping rods 12 guide the EPDM film. The rodless cylinder 10 is started to drive the sliding block 9 to slide on the limiting rod 8 away from the end of the feed roll 2. The sliding block 9 drives the first bidirectional cylinder 11 to slide away from the end of the feed roll 2. The first bidirectional cylinder 11 drives the end of the EPDM film to slide away from the end of the feed roll 2 through the two clamping rods 12 until the two clamping rods 12 drive the end of the EPDM film to slide through the two collision mechanisms. The two collision mechanisms respectively clamp a sealing strip. The sealing strip is bonded to the two sides of the EPDM film through the two collision mechanisms to achieve the bonding operation of the EPDM film and the sealing strip. At the same time, the first driving member 4 is started (the first driving member 4 is a device with an output end capable of forward and reverse motion, preferably a motor) to drive the recovery roll 3 to rotate, so that the recovery roll 3 winds and recycles the stripping film 5. There is no need for the staff to manually recycle the stripping film 5, so that the stripping film 5 can be reused, reducing the waste of the stripping film 5.

[0026] The disadvantage of the existing technology is that the peeling film 5 needs to be recycled when the EPDM film is bonded. Most of the existing methods require staff to recycle the peeling film 5, but the staff does not completely rewind the peeling film 5, resulting in a certain amount of waste of the peeling film 5.

[0027] The beneficial effects of the present invention are: the EPDM film is unwound by the feed roll 2, and then the staff and the separation mechanism separate the EPDM film into EPDM film and stripping film 5, and the EPDM film is pulled linearly by the traction mechanism and pulled out through the two collision mechanisms, and the two collision mechanisms respectively clamp a sealing strip, and then the two collision mechanisms bond the sealing strip to the opposite sides of the EPDM film, thereby realizing the bonding process of the sealing strip and the EPDM film, and the stripping film 5 is wound and recycled by the recovery roll 3, and there is no need for the staff to manually recycle the stripping film 5, so that the stripping film 5 can be reused, reducing the waste of the stripping film 5, and the feed roll 2 can continuously feed the EPDM film to realize the continuous recycling of the stripping film 5.

[0028] Furthermore, two collision mechanisms are symmetrically provided at the top of the carrier 1 , and the collision mechanisms include a second driving member 15 . Two second driving members 15 are symmetrically provided at the top of the carrier 1 , and the output ends of the two second driving members 15 are each connected to a pair of collision dies 16 .

[0029] Specifically, when the sliding block 9 drives the first bidirectional cylinder 11 to slide away from the end of the feed roll 2, the first bidirectional cylinder 11 drives the end of the EPDM film to slide away from the end of the feed roll 2 through the two clamping rods 12 until the two clamping rods 12 drive the end of the EPDM film to slide beyond the edge of the collision mold 16. The staff or the loading mechanism (such as: a robot or other equipment capable of loading) places the sealing strip on the collision mold 16 and starts the two second driving members 15 at the same time (the second driving member 15 is a device with a linear reciprocating motion at the output end, preferably a cylinder, an electric push rod, etc.) to drive the collision mold 16 to slide toward one end close to each other, so that the two collision molds 16 bond the sealing strip to the opposite sides of the EPDM film, thereby realizing the bonding between the sealing strip and the PDM film. After the EPDM film reaches the curing time and the bonding strength between the sealing strip and the PDM film is reached, the two second driving members 15 are started at the same time to drive the collision mold 16 to slide away from each other.

[0030] Furthermore, a guide plate 17 is provided on the carrier 1 ; a guide groove is provided on the guide plate 17 ; a second bidirectional cylinder 18 is provided on the guide plate 17 ; and two output ends of the second bidirectional cylinder 18 are each connected to a cutting knife 19 .

[0031] Specifically, when the staff is pulling the EPDM film, the staff is pulling the EPDM film through the guide groove and the part between the two cutting knives 19, and then the two clamping rods 12 clamp the ends of the EPDM film; when the two collision dies 16 bond the sealing strip to the opposite sides of the EPDM film, the second bidirectional cylinder 18 is started to synchronously drive the two cutting knives 19 to move toward one end close to each other, so that the two cutting knives 19 cut the EPDM film until the two cutting knives 19 cut the EPDM film, and then the second bidirectional cylinder 18 synchronously drives the two cutting knives 19 to move toward one end away from each other. When the EPDM film reaches the curing time and the bonding strength between the sealing strip and the EPDM film is reached, the two second driving members 15 are started at the same time to drive the collision dies 16 to slide toward one end away from each other, so that the two collision dies 16 release the clamping of the EPDM film, remove the corresponding EPDM film, and the bonding operation of the EPDM film is completed.

[0032] After the staff takes out the bonded EPDM film, they start the rodless cylinder 10 to drive the sliding block 9 to slide on the limiting rod 8 toward one end of the feed roll 2. The sliding block 9 drives the end of the EPDM film to slide toward one end of the feed roll 2 through the first bidirectional cylinder 11 and the two clamping rods 12 until the two clamping rods 12 slide close to the position of the cutting knife 19. The first bidirectional cylinder 11 is started to drive the two clamping rods 12 to clamp the end of the EPDM film. Repeating the above operations can continuously perform bonding operations on the sealing strip and EPDM film.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
