Description

Technical Field

[0001] This utility model relates to the fields of TPV corner fitting equipment and material dropping by tapping, specifically to a timed material dropping device for TPV corner fitting equipment. Background Technology

[0002] TPV corner splicing equipment uses adhesive or glue to bond two rubber strips with the same cutting angle together to form a right-angled rubber strip frame, which can be used for sealing car windows or doors. Traditional corner splicing operations require manual intervention or manual operation of material discharge and unloading after splicing, which is inefficient.

[0003] Existing TPV corner splicing equipment has low material discharge and unloading efficiency and often requires manual intervention. For example, CN212556594U discloses an anti-cracking adhesive laying structure for TPV corner splicing of a joint strip, which includes a top strip, a B-pillar joint strip corner splice, and a B-pillar joint strip. The B-pillar joint strip corner splice includes a corner body, an extension on one side of the corner body corresponding to the B-pillar joint strip, a first joint surface on the corner body, a second joint surface on the inner side of the extension, a third joint surface and a fourth joint surface on the top of the B-pillar joint strip, the third joint surface being the top surface of the entire B-pillar joint strip, and the fourth joint surface being located at the top of the side of the B-pillar joint strip. The first joint surface matches the third joint surface, and the second joint surface matches the fourth joint surface. This utility model divides the joint between the B-pillar joint strip and the joint area of ​​the B-pillar joint strip into two sections, forming a small difference in size, which increases the area of ​​the joint area. The extended B-pillar joint strip covers the B-pillar joint strip, thereby increasing the tensile and shear resistance of the joint area and reducing the problem of joint cracking. However, the jointing operation and material discharge in this solution require manual operation, including material discharge and dropping.

[0004] Therefore, it is necessary to invent a timed knocking and dropping device for TPV corner fitting equipment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a timed tapping and dropping device for TPV corner splicing equipment, in order to solve the problem of material not being easily discharged or dropped after the corner splicing operation of the rubber strip in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A timed tapping and dropping device for TPV corner joint equipment includes a main body, a glue injection mechanism, a glue injection port, a glue injection channel, a corner joint channel, and a clamping component. The main body is provided with a track, on which the glue injection mechanism is slidably connected. The glue injection mechanism is driven by a cylinder. A glue injection port is installed at the bottom of the glue injection mechanism. The glue injection port is aligned with the glue injection channel directly below it before glue is injected. The main body is also provided with a corner joint channel, which is open. A clamping component is provided to fit the corner joint channel. The clamping component can seal after contacting the opening of the corner joint channel. The clamping component is driven by a cylinder, and a tapping mechanism is connected to the bottom of the clamping component.

[0008] Preferably, the striking mechanism includes a connecting rod fixedly connected to the bottom of the clamping member, a protrusion and a second spring connected to the bend end of the connecting rod, and a striking ball connected to the end of the second spring.

[0009] Preferably, the length of the connecting rod is slightly greater than the distance between the corner channel and the clamping member in the initial state, and the connecting rod is L-shaped.

[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0011] This invention utilizes a striking mechanism on the clamping component to create a gap between the workpiece and the corner channel after corner jointing operations are completed. This facilitates material discharge and unloading. The entire striking mechanism is driven by the clamping force of the clamping component, eliminating the need for external force or additional power sources, thus being more energy-efficient and environmentally friendly. The striking ball on the striking mechanism strikes the side of the push plate, creating a gap that facilitates material discharge and unloading. During the clamping component's reset process, the striking ball pushes the push plate a further distance, ejecting the material. Simultaneously, under the action of spring one and track two, the material quickly resets to a state of contact with the inner wall of the corner joint channel. The entire discharge and unloading process requires no external force or manual intervention, resulting in high efficiency. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model provides, for example Figures 1-3 The TPV corner fitting equipment shown includes a timed tapping and dropping device, comprising a main body 1, a glue injection mechanism 3, a glue injection port 5, a glue injection channel 6, a corner fitting channel 7, and a clamping member 8. The main body 1 is provided with a track 1 2, and the glue injection mechanism 3 is slidably connected to the track 1 2. The glue injection mechanism 3 is driven by a cylinder 1 4. The glue injection port 5 is installed at the bottom of the glue injection mechanism 3. After the glue injection port 5 is aligned with the glue injection channel 6 directly below it, glue is injected. The main body 1 is also provided with a corner fitting channel 7, which is open. A clamping member 8 is provided to fit the corner fitting channel 7. The clamping member 8 can seal after contacting the opening of the corner fitting channel 7. The clamping member 8 is driven by a cylinder 2 9. A tapping mechanism is connected to the bottom of the clamping member 8. The tapping mechanism includes a connecting rod 801 fixedly connected to the bottom of the clamping member 8, a protrusion 802 and a spring 2 803 connected to the turning end of the connecting rod 801, and a tapping ball 804 connected to the end of the spring 2 803.

[0021] By utilizing the striking mechanism in conjunction with the corner channel 7, gaps are created in the glued and fixed adhesive strip frame workpiece within the corner channel 7, facilitating material discharge and unloading. This invention can achieve timed striking motions according to actual production rhythm requirements and driven by the clamping component 8 driven by the cylinder 9.

[0022] The length of the connecting rod 801 is slightly greater than the distance between the initial corner channel 7 and the clamping member 8, and the connecting rod 801 is L-shaped. The protrusion 802 is composed of two mirror-symmetrical frustums, and the maximum diameter of the protrusion 802 is slightly greater than the distance between the limiting members 704. The protrusion 802 is made of rubber. The limiting member 704 is fixedly connected to the corner channel 7, and the limiting member 704 is composed of two long strips that are longitudinally aligned in a straight line. The two long strips can directly contact the protrusion 802.

[0023] By utilizing the special shape of the protrusion 802 on the connecting rod 801 and the interference fit between it and the limiting member 704, a compressive force is generated, which is then converted into the force of the striking ball 804 striking the pusher member 701.

[0024] Both sides of the corner channel 7 are provided with through holes. The shape and size of the through holes are adapted to the pusher 701. The bottom of the pusher 701 is provided with a second track 703. The pusher 701 is a rectangular block. The two sides of the rectangular block are higher than the middle position. One end of the first spring 702 is fixedly connected to both sides of the pusher 701 that are higher than the middle position. The other end of the first spring 702 is fixedly connected to the inner wall of the corner channel 7.

[0025] When the striking ball 804 strikes the pusher 701, it creates a gap in the rubber strip frame workpiece in the corner channel 7 to facilitate material discharge and dropping. Then, the pusher 701 is pushed a certain distance into the corner channel 7 to push the material out of the corner channel 7.

[0026] Working principle of this utility model:

[0027] Refer to the instruction manual appendix Figures 1-3 When using this utility model, firstly, two cut adhesive strips (often cut at a 45° angle, forming a 90° adhesive strip frame after being properly fitted) that need to be joined at the corner are transported from two directions of the corner joining channel 7, then clamped and fixed by the clamping member 8, and finally the glue injection port 5 on the glue injection mechanism 3 is aligned with the glue injection channel 6 to inject glue into the corner for bonding and fixing.

[0028] Refer to the instruction manual appendix Figures 3-5 When using this utility model, when the fixed rubber strip frame needs to be unloaded, as the clamping member 8 retracts and returns to its original position, the connecting rod 801, which was not originally in contact with the corner channel 7, slowly moves towards the pushing member 701. When it passes the limiting member 704, due to the special shape of the protrusion 802, a certain squeezing force is applied to the protrusion 802. When the protrusion 802 passes through the limiting member 704, there will be a process of accumulating and exerting force, so that the striking ball 804 is heavily struck onto the pushing member 701, and the rubber strip frame material in the corner channel 7 is made to have gaps due to being struck and swayed, making it easier to drop the material.

[0029] After the pusher 701 is struck, as the clamping part 8 returns to its original position, the striking ball 804 is pushed further into the corner channel 7, causing the pusher 701 to move a certain distance into the corner channel 7, pushing out and dropping the rubber strip frame material in the corner channel 7. Under the action of the spring 702 and the track 703, the pusher 701 can be smoothly reset to a state of contact with the corner channel 7, and the operation is repeated.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
