Description

Technical Field

[0001] The present invention relates to the technical field of felt processing, and in particular to an automatic felt clamping device and method. Background Art

[0002] Car glass spikes, also known as car glass clips or fixing buckles, are components used to fix car glass. When a car is driving, it will be affected by road bumps, vibrations, etc. When the glass is in direct contact with the spikes, rigid collisions are likely to occur. Therefore, felt needs to be placed on the spikes for cushioning, noise reduction, and protection.

[0003] The felt has its own adhesive backing. The working process of the felt clamping device is to feed the button first, then use the machine head to stick the felt on the product, and then use the clamping chuck to completely attach the felt to the product, and finally unload the material. However, in the actual operation process, it was found that since the button is fed in a centralized manner, affected by the workshop environment, there will be dust and impurities on the surface of the button. The residual impurities will form a tiny gap between the felt and the button, hindering the close contact between the adhesive backing and the surface of the button, resulting in a significant decrease in bonding strength, causing the felt to shift and fall off, thereby affecting the use effect of the button. Summary of the Invention

[0004] The purpose of the present invention is to provide an automated felt clamping device and method to solve the following technical problems: due to the influence of the workshop environment, dust and impurities will exist on the surface of the button.

[0008] The first cylinder is connected to an air inlet pipe, which is connected to an air source. The second cylinder is connected to an air outlet pipe on a side wall away from the first cylinder. An air outlet head is installed at one end of the air outlet pipe. A force-bearing mechanism is provided between the movable rod and the connecting pipe. When the positioning mechanism fixes the nail button, the second cylinder rotates and blows air to clean impurities on the surface of the nail button.

[0012] As a further solution of the present invention: a support rod is fixed on the bottom wall of the first cylinder, a support plate is fixed to one end of the support rod, and a limiting mechanism is provided on the upper surface of the support plate.

[0013] As a further solution of the present invention: the limiting mechanism includes a sleeve fixed on the support plate, a limiting rod is movably provided on the top of the sleeve, the bottom end of the limiting rod is connected to a piston block, the bottom of the piston block is connected to a second spring, and a branch pipe is connected between the top of the sleeve and the first cylinder.

[0014] A method for using an automated felt holding device comprises the following steps:

[0015] S1, feed the product and place it on the positioning seat of the first station through the chuck;

[0016] S2. The turntable rotates 90° to move the product into the second station. The positioning mechanism fixes the product and cleans the surface of the product. The felt is then pasted onto the product through the machine head.

[0017] S3. The turntable rotates 90° again, and the product enters the third station. The felt is clamped tightly by the clamping chuck so that the felt is completely attached to the product.

[0018] S4, the turntable rotates 90 degrees again, and the product enters the fourth station to complete unloading.

[0019] Beneficial effects of the present invention:

[0020] (1) The present invention improves the stability of the product by setting a positioning mechanism. On the other hand, the positioning mechanism is provided with a first cylinder, a second cylinder, an air outlet pipe and an air outlet head. After the positioning head fixes the product, under the action of the force-bearing mechanism, the second cylinder rotates around the product and blows air to clean the surface impurities. Then the felt is pasted, ensuring the pasting quality of the felt and the button, and giving full play to its buffering, sealing and other functions.

[0021] (2) The present invention sets a force-bearing mechanism. When the positioning head is not in contact with the product, the sealing block blocks the connecting pipe, preventing the gas from being discharged. When the positioning head is in contact with the product, the force is removed from the connecting pipe, and the gas can enter the second cylinder through the connecting pipe and then be blown out through the air outlet pipe and the air outlet head. The air inlet pipe is facing the force-bearing plate, and at the same time, the force-bearing plate and the connecting pipe are blown to rotate, so that the air outlet head moves around the product, and the cleaning is more comprehensive.

[0022] (3) The present invention sets a limiting mechanism. In order to prevent the air outlet head from rotating above the product and affecting the pasting of the felt, the limiting rod of the limiting mechanism can be automatically extended, thereby limiting the air outlet head during the rotation process, causing it to stop rotating during the pasting process of the felt, thereby ensuring smooth pasting.

A movable rod 305 is movably provided on the side wall of the cylinder 304 away from the first cylinder 303, and a positioning head 306 is fixed at one end of the movable rod 305; an air inlet pipe 310 is connected to the first cylinder 303, and the air inlet pipe 310 is connected to the air source, and an air outlet pipe 311 is connected to the side wall of the second cylinder 304 away from the first cylinder 303, and an air outlet head 312 is installed at one end of the air outlet pipe 311, and a force-bearing mechanism is provided between the movable rod 305 and the connecting pipe 307. When the positioning mechanism 3 fixes the nail button, the second cylinder 304 rotates and blows air to clean impurities on the surface of the nail button. The equipment body 1 is provided with a first station, a second station, a third station and a fourth station. The first station is a feeding station, the positioning mechanism 3 is located at the second station, the third station is provided with a clamping chuck 5, and the fourth station is a unloading station; the upper surface array of the turntable 2 is provided with four positioning seats 4, and the upper surface of the turntable 2 is provided with a negative pressure mechanism to adsorb the buttons on the positioning seats 4; after the product enters the first station, the chuck places the product on the positioning seat 4 of the first station, and then the turntable 2 rotates 90°, the product enters the second station, the positioning mechanism 3 is started, the positioning head 306 fixes the product, and the air source continuously supplies air. At this time, under the action of the force-bearing mechanism, the gas is blown out through the air outlet pipe 311 and the air outlet head 312, and the air outlet head 312 moves around the product to complete a comprehensive cleaning of the product surface. It is worth noting that the driving source can be a cylinder and the air source can be an air pump or a fan. The specific model is selected according to the actual situation and will not be elaborated here.

[0034] See Figure 4 and Figure 5The force-bearing mechanism includes a sealing block 308 fixed to the end of the movable rod 305, one end of the sealing block 308 is connected to the first spring 309, one end of the first spring 309 is connected to the side wall of the first cylinder 303, the connecting pipe 307 is located on the side wall of one end of the first cylinder 303, and a plurality of force-bearing plates 320 are adhered and provided, and the air inlet end of the air inlet pipe 310 is facing the force-bearing plate 320; in the initial state, when the positioning head 306 is not in contact with the product, the sealing block 308 will be connected The tube 307 is blocked to prevent the gas from being discharged. When the positioning head 306 comes into contact with the product, the sealing block 308 is removed from the connecting tube 307, and the gas can enter the second cylinder 304 through the connecting tube 307, and then be blown out through the air outlet pipe 311 and the air outlet head 312. The air inlet pipe 310 is facing the force-bearing plate 320. The gas blows the force-bearing plate 320 and the connecting tube 307 to rotate, which can rotate the second cylinder 304 and make the air outlet head 312 move around the product for more comprehensive cleaning.

[0035] See Figure 4 and Figure 6 318 is a kind of spring that is fixed on the cam face of the cam 316, and the cam face 319 is a kind of spring that is fixed on the cam face of the cam 316. The air head 312 rotates to the top of the product and affects the pasting of the felt. In the initial state, since the pressure cannot be released, part of the gas enters the sleeve 315 through the branch pipe 317. Under the action of air pressure, the piston block 318 and the limiting rod 316 move downward and squeeze the second spring 319. When the positioning head 306 contacts the product, the gas is discharged and the pressure inside the sleeve 315 is also released. At this time, the limiting rod 316 rises, and after the air outlet head 312 rotates to the bottom, it is limited so that it cannot continue to rotate, thereby facilitating the smooth pasting of the felt.

[0036] A method for using an automated felt holding device comprises the following steps:

[0037] S1. Feed the product and place it on the positioning seat 4 of the first station through the chuck;

[0038] S2, turntable 2 rotates 90 degrees to make the product enter the second station, positioning mechanism 3 fixes the product, cleans the product surface, and sticks the felt on the product through the machine head;

[0039] S3, the turntable 2 rotates 90 degrees again, and the product enters the third station, and the felt is clamped by the clamping chuck 5 so that the felt is completely attached to the product;

[0040] S4, turntable 2 rotates 90° again, and the product enters the fourth station to complete unloading.

[0041] The working principle of the present invention is as follows: after the product enters the first station, the chuck places the product on the positioning seat 4 of the first station, then the turntable 2 rotates 90°, and the product enters the second station. The driving source (not shown) pushes the driving rod 302 to move toward the product, and the air source (not shown) continuously supplies air. When the positioning head 306 contacts the product and continues to move a certain distance, the product can be fixed and the movable rod 305 and the sealing block 308 can be pushed to move. The sealing block 308 is moved out of the connecting pipe 307, and the gas can enter the second cylinder 304 through the connecting pipe 307, and then be blown out through the air outlet pipe 311 and the air outlet head 312. The air inlet pipe 310 is facing the force-bearing plate 320. The gas blows the force-bearing plate 320 and the connecting pipe 307 to rotate, which can rotate the second cylinder 304 and make the air outlet head 312 move around the product, thereby comprehensively cleaning the surface of the product.

[0042] At this time, the pressure inside the sleeve 315 is also relieved, and the limit rod 316 gradually rises. After the air outlet head 312 rotates to the bottom, the limit rod 316 limits it so that it cannot continue to rotate. At this time, the machine head (not shown) sticks the felt to the product. After the felt is stuck, the drive source is started to reset the drive rod 302, and the positioning head 306 is separated from the product. Under the action of the first spring 309, the sealing block 308 re-enters the connecting pipe 307. Since the interior of the first cylinder 303 is relatively sealed at this time, as gas continues to enter and cannot be discharged, the air pressure in the first cylinder 303 gradually increases, and the air pressure difference between the inside and outside gradually decreases. The reduced air pressure difference directly leads to a significant decrease in the speed of the blown air flow. At this time, the connecting pipe 307 cannot rotate, and some gas enters the sleeve 315 through the branch pipe 317, causing the limit rod 316 to descend and reset, facilitating the next positioning and cleaning. It is worth noting that the positioning and felt sticking process only takes a few seconds, so there is no danger of excessive air pressure.

[0043] After the felt is pasted, the turntable 2 rotates 90° again, and the product enters the third station. The felt is clamped by the clamping chuck 5 so that the felt is completely attached to the product. Finally, the turntable 2 rotates to the fourth station to complete the unloading of the product.

[0044] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
