Description

Technical Field

[0001] This utility model relates to the field of gripping devices, and more particularly to a gripping device for assembling plastic parts. Background Technology

[0002] The plastics industry has achieved unprecedented rapid development thanks to the diversity of its materials, ease of processing, and wide range of applications. From everyday consumer goods to industrial components, from medical equipment to automobile manufacturing, plastic parts are ubiquitous, directly driving the continuous expansion of plastic parts production scale.

[0003] Application No. 202422168530.9 discloses an engineering plastic part gripping device, including a frame with an adjustment mechanism on the top and a gripping mechanism on one side of the adjustment mechanism. The gripping mechanism includes a drive cylinder, a third drive motor, a first connecting plate, a connecting column, a connecting plate, a threaded column, a clamping frame, a second connecting plate, a movable block, a connecting block, and mounting components. This invention, through the gripping mechanism, uses the third drive motor to rotate the connecting column, causing the threaded column to move up and down, thereby controlling the opening and closing of the clamping frame. This allows for flexible adjustment of the clamping range of the clamping frame according to different sizes of plastic parts. The adjustment mechanism is designed with one end of a first sliding plate embedded in the inner wall of a first sliding groove, and one side of a second sliding plate embedded in the inner wall of a second sliding groove. This design ensures smoother sliding under pressure, reducing the risk of gripping failure or damage to the plastic part due to shaking.

[0004] The above-mentioned solution has shortcomings in use. When gripping plastic parts, it can only clamp the outside of the plastic parts. It is difficult to form a stable friction force when clamping the outside, which can easily cause the plastic parts to slip and fall off, further affecting the assembly efficiency of the plastic parts. Therefore, we provide a gripping device for assembling plastic parts. Utility Model Content

[0014] Preferably, a set of limiting rods is fixedly connected to the upper surface of the double-tooth plate, and each limiting rod is fitted with a limiting tube, the top end of each limiting tube being connected to the bottom surface of the top of the U-shaped frame.

[0015] Beneficial effects:

[0016] 1. By setting up gripping components, the plastic parts can be clamped on the outside first, and then the bottom of the clamped plastic parts can be shielded and protected to block the vertical falling path of the plastic parts, which can effectively prevent them from slipping and falling off, ensuring the stability of the plastic parts throughout the gripping and assembly process, ensuring that the assembly process is carried out continuously and efficiently, and significantly improving the assembly efficiency of plastic parts.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] As attached Figure 1 With appendix Figure 2 As shown: A gripping device for assembling plastic parts includes a three-axis robot 1. The three-axis robot 1 can facilitate subsequent assembly work through coordinated movements in the X, Y, and Z directions. A gripping component 2 is installed at one end of the three-axis robot 1. The gripping component 2 includes a U-shaped frame 201 mounted on the three-axis robot 1. An electric push rod 202 is mounted on the bottom surface of the top of the U-shaped frame 201. The U-shaped frame 201 is used to mount the electric push rod 202 to ensure its normal operation. A double-toothed plate 203 is installed at the telescopic end of the electric push rod 202. The output end of the electric push rod 202 can drive the double-toothed plate 203 to move.

[0027] As attached Figure 2 With appendix Figure 5As shown: A set of mounting slots 204 are symmetrically opened at the bottom of the U-shaped frame 201. A half-gear 205 is rotatably connected to the inner wall of each mounting slot 204, which is used to mount the half-gear 205. Each half-gear 205 meshes with a double-toothed plate 203. The electric push rod 202 provides power to the double-toothed plate 203. The meshing of the half-gear 205 with the double-toothed plate 203 enables the rotation of the half-gear 205. A set of limiting rods 214 are fixedly connected to the upper surface of the double-toothed plate 203. Each limiting rod 214 is fitted with a limiting tube 215, and the top end of each limiting tube 215 is connected to the bottom surface of the top of the U-shaped frame 201. The cooperation of the limiting rods 214 and the limiting tubes 215 ensures that the double-toothed plate 203 maintains stable vertical lifting and lowering, preventing tooth disengagement, jamming, and other phenomena, and ensuring smooth and reliable opening and closing of the clamping structure.

[0028] As attached Figure 2 As shown: Each half gear 205 has a reinforcing rod 210 fixedly connected to both its left and right sides. The other end of each reinforcing rod 210 is rotatably connected to the outer surface of the U-shaped frame 201, and the axis of the reinforcing rod 210 is the same as the axis of rotation of the half gear 205. The reinforcing rod 210 is used to reinforce the rotational movement of the half gear 205 and prevent transmission jamming or uneven clamping force caused by the positional deviation of the half gear 205.

[0029] As attached Figure 2 Appendix Figure 3 With appendix Figure 4 As shown, the gripping assembly 2 also includes a clamping structure for gripping plastic parts mounted on a set of half-gears 205, and a lifting structure mounted on the clamping structure to prevent the gripped plastic parts from falling off. The clamping structure includes a connecting plate 206 fixedly connected to the outer surface of each half-gear 205, and a clamping frame 207 fixedly connected to the other end of each connecting plate 206. When the half-gears 205 rotate, the distance between the two clamping frames 207 can be adjusted to grip the plastic parts. The lifting structure includes a motor 208 mounted on one side of one of the clamping frames 207 and a support frame 209 rotatably connected to the outer surface of that clamping frame 207. The output end of the motor 208 is connected to the outer surface of the support frame 209. The motor 208 drives the support frame 209 to rotate, shielding and protecting the plastic parts clamped between the clamping frames 207, effectively preventing them from slipping and falling off, and ensuring the smooth assembly process of the plastic parts.

[0030] As attached Figure 2 With appendix Figure 3As shown: Each connecting plate 206 has a reinforcing plate 211 fixedly connected to both its left and right sides, and the other end of each reinforcing plate 211 is connected to the upper surface of the clamping frame 207. The reinforcing plates 211 ensure the effectiveness of the clamping frame 207. Anti-slip pads 212 are installed on the sides of the two clamping frames 207 that are close to each other, which greatly increases the friction between the clamping frame 207 and the surface of the plastic part, ensuring the gripping effect of the clamping frame 207. A limiting block 213 is fixedly connected to the side of one of the clamping frames 207 closest to the support frame 209. The limiting block 213 can block the support frame 209, preventing collision between the support frame 209 and the clamping frame 207.

[0031] Working principle: When gripping a plastic part, the three-axis robot arm 1 is controlled to move the clamping frame 207 to the outside of the plastic part. Then, the electric push rod 202 is controlled to retract, which drives the double toothed plate 203 to move synchronously. The double toothed plate 203 drives the half gear 205 to rotate, which in turn drives the connecting plate 206 and the clamping frame 207 to deflect synchronously. The clamping frame 207 will then clamp the outside of the plastic part. Then, the motor 208 is controlled to work, which drives the support frame 209 to deflect to the bottom of the clamping frame 207, thereby shielding and protecting the plastic part clamped between the clamping frames 207. This effectively prevents it from slipping and falling off, ensuring the assembly efficiency of the plastic part.
