Description

Technical Field

[0001] This utility model relates to the field of adsorption tool technology, and in particular to a manual adsorption and pickup device for workpieces. Background Technology

[0002] In actual production, scratches, dents, and dirt were found on the surface of the bracket cover when the C-corner high-gloss edge was machined. The cause was found to be that after the product was machined, aluminum shavings from the machining process adhered to the high-gloss edge when the product was handled with a hand wearing finger cots. Handling the product by hand would cause scratches, dents, and dirt on the high-gloss surface. In practice, a rubber suction head was used to adsorb the bracket cover, thus replacing the hand in removing the workpiece.

[0003] The existing principle of rubber suction heads adsorbing workpieces is to create negative pressure by pressing the cylinder to expel air and generate suction force. This method has certain drawbacks. When manually squeezing the cylinder, the amount of air expelled each time is inconsistent. When the amount of air expelled is insufficient, the suction force is correspondingly insufficient, which can easily cause the workpiece to fall off. Secondly, existing suction heads can usually be replaced to meet the adsorption requirements of different workpieces. Different suction heads require different amounts of air. For smaller suction heads, expelling excessive air may lead to over-compression, damaging the suction head or making it difficult to restore it to its original shape. Therefore, we propose a manual workpiece adsorption and pickup device to solve this problem. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a manual workpiece adsorption and pickup device, which can more accurately solve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a manual workpiece adsorption and pickup device, comprising a top body, a rubber cylinder, and a base. The top body, rubber cylinder, and base are fixedly connected in sequence from top to bottom. Two external frames are fixedly connected to the outer sides of the top body and the base. A sliding plate is slidably fitted on the outer side of the external frame. A squeezing mechanism is provided on one side of the sliding plate. The two squeezing mechanisms cooperate to squeeze out the air inside the rubber cylinder. A limiting plate is fixedly installed on the outer side of the external frame. The limiting plate limits the movement distance of the sliding plate to control the amount of air squeezed out of the rubber cylinder.

[0007] Furthermore, the extrusion mechanism includes a rotating seat, which is fixedly connected to a corresponding external frame. A rotating plate is rotatably mounted on the rotating seat. A torque spring is directly fixedly connected between the rotating seat and the rotating plate. A mounting plate is rotatably mounted on one side of the rotating plate, and a magnetic plate is fixedly mounted on one side of the mounting plate. Two magnetic plates located on different sides cooperate with each other.

[0008] Furthermore, a plurality of arc-shaped grooves are provided on one side of the mounting plate, and the same round rod is fixedly installed between the inner walls of the left and right sides of the arc-shaped grooves. Rollers are rotatably sleeved on the outer side of the round rod, and the plurality of rollers located on the same vertical line are configured as wheel sets, and the plurality of wheel sets located on different sides are staggered.

[0009] Furthermore, one side of the external frame is provided with multiple threaded grooves, and one side of the limiting plate is provided with a threaded hole. The same bolt is installed in the threaded hole and the corresponding threaded groove.

[0010] Furthermore, a vertical groove is provided on one inner wall of the external frame, and a sliding hole is provided on the top of the slide plate. The external frame is slidably installed in the corresponding sliding hole. A guide plate is fixedly installed on one inner wall of the sliding hole, and the guide plate is slidably installed in the corresponding vertical groove.

[0011] Furthermore, a return spring is fixedly connected to the bottom of the guide plate, and one end of the return spring is fixedly connected to the inner wall of one side of the corresponding vertical groove.

[0012] Furthermore, the top of the top body has a groove, and the bottom inner wall of the groove has a vertical hole. The vertical hole is connected to the rubber cylinder body. A vertical rod is slidably installed in the vertical hole. A circular plate is fixedly installed at the top of the vertical rod. Multiple air passage grooves are opened on the outer side of the vertical rod. Multiple side grooves are provided on the inner wall of the vertical hole. The air passage grooves and side grooves cooperate with each other. The same support spring is fixedly installed between the circular plate and the bottom inner wall of the groove.

[0013] Furthermore, a fixing rod is fixedly installed on the base, and an adsorption head is slidably sleeved on the outer side of the fixing rod. The fixing rod is connected to the rubber cylinder body and the adsorption head respectively.

[0014] The beneficial effects of this utility model are as follows:

[0015] By driving two sliding plates to move downwards synchronously, the two rotating plates rotate towards each other under the action of torque springs, thereby driving the two mounting plates to move closer together. Then, the two magnetic plates attract and stick to each other, thus flattening the rubber cylinder. The two mounting plates move downwards together with the sliding plates, thereby expelling the air from the rubber cylinder, thus ensuring that the deformation of the rubber cylinder is consistent each time. The displacement of the sliding plates is limited by the limiting plate. The two methods work together to control the amount of air expelled from the rubber cylinder in a single cycle.

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0024] Please refer to Figures 1-5 The present invention proposes a manual adsorption and pickup device for workpieces, comprising a top body 1, a rubber cylinder 2, and a base 3. The top body 1, the rubber cylinder 2, and the base 3 are fixedly connected from top to bottom. Two external frames 4 are fixedly connected to the outer sides of the top body 1 and the base 3. A sliding plate 5 is slidably mounted on the outer side of the external frame 4. A squeezing mechanism is provided on one side of the sliding plate 5. The two squeezing mechanisms cooperate to squeeze out the air inside the rubber cylinder 2. A limiting plate 13 is fixedly installed on the outer side of the external frame 4. The limiting plate 13 limits the amount of air squeezed out of the rubber cylinder 2 by restricting the movement distance of the sliding plate 5.

[0025] like Figure 3 As shown, the extrusion mechanism includes a rotating seat 6, which is fixedly connected to a corresponding external frame 4. A rotating plate 7 is rotatably mounted on the rotating seat 6. A torque spring 8 is directly fixedly connected between the rotating seat 6 and the rotating plate 7. An mounting plate 9 is rotatably mounted on one side of the rotating plate 7. A magnetic plate 10 is fixedly mounted on one side of the mounting plate 9. The two magnetic plates 10 located on different sides cooperate with each other.

[0026] Multiple arc-shaped grooves are provided on one side of the mounting plate 9. The same round rod is fixedly installed between the inner walls of the left and right sides of the arc-shaped grooves. Rollers 11 are rotatably sleeved on the outer side of the round rod. Multiple rollers 11 located on the same vertical line are set as wheel groups. Multiple wheel groups located on different sides are staggered. When the two mounting plates 9 are put together under the action of the magnetic plate 10, the rolling on one side is connected to the rolling on one side of the mounting plate 9 on the other side. The setting of multiple rollers 11 reduces the friction between the two mounting plates 9, making it easier for the two mounting plates 9 to move downward in the put-together state.

[0027] In practical use, the first step is to place the palm against the top of the top body 1, hold the top body 1 with several fingers, and push the slide plate 5 downward with two fingers until the slide plate 5 comes into contact with the limiting plate 13. During the downward movement of the slide plate 5, the two rotating plates 7 rotate towards each other under the action of the torque spring 8, thereby driving the two mounting plates 9 to come closer to each other. Then the two magnetic plates 10 attract each other and stick together, thereby flattening the rubber cylinder 2. The two mounting plates 9 move downward together with the slide plate 5, thereby expelling the air inside the rubber cylinder 2.

[0028] like Figure 1 As shown, the outer frame 4 has multiple threaded grooves 12 on one side, and the limiting plate 13 has a threaded hole on one side. The threaded hole and the corresponding threaded groove 12 are threaded with the same bolt, which makes it easy to set the relative height of the limiting plate 13 on the outer frame 4, thereby limiting the displacement of the slide plate 5 to control the amount of air compressed out of the rubber cylinder 2.

[0029] like Figure 3 and Figure 4 As shown, a vertical groove 14 is provided on one inner wall of the outer frame 4, and a sliding hole is provided on the top of the slide plate 5. The outer frame 4 is slidably installed in the corresponding sliding hole. A guide plate 15 is fixedly installed on one inner wall of the sliding hole. The guide plate 15 is slidably installed in the corresponding vertical groove 14. A return spring 16 is fixedly connected to the bottom of the guide plate 15. One end of the return spring 16 is fixedly connected to one inner wall of the corresponding vertical groove 14, which plays the role of guiding the movement and resetting the slide plate 5.

[0030] like Figure 4As shown, the top of the top body 1 has a groove 17, and the bottom inner wall of the groove 17 has a vertical hole 21. The vertical hole 21 is connected to the rubber cylinder body 2. A vertical rod 18 is slidably installed in the vertical hole 21. A circular plate 19 is fixedly installed at the top of the vertical rod 18. Multiple air passages 20 are provided on the outside of the vertical rod 18. Multiple side grooves 22 are provided on the inner wall of the vertical hole 21. The air passages 20 and the side grooves 22 cooperate with each other. The same support spring is fixedly installed between the circular plate 19 and the bottom inner wall of the groove 17. By pressing the circular plate 19 downward, the vertical rod 18 is driven to move downward, so that the air passages 20 and the side grooves 22 are connected, and air enters the rubber cylinder body 2, so that the negative pressure in the rubber cylinder body 2 is eliminated and the adsorption force disappears, thus facilitating the removal of the workpiece.

[0031] like Figure 5 As shown, a fixing rod 23 is fixedly installed on the base 3. An adsorption head 24 is slidably sleeved on the outside of the fixing rod 23. The fixing rod 23 is connected to the rubber cylinder body 2 and the adsorption head 24 respectively, which facilitates the replacement of the adsorption head 24.

[0032] In practical use, the second step is as follows: After the first step, a certain amount of air is discharged from the rubber cylinder 2, which tightly adheres the adsorption head 24 to the bottom of the workpiece. The slide plate 5 is released, and the reset spring 16 drives the slide plate 5 and the two mounting plates 9 to move upward synchronously, forming a negative pressure inside the rubber cylinder 2, so that the adsorption head 24 can firmly adsorb the workpiece.

[0033] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
