Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, and more specifically to a fully automatic assembly equipment for pistons and sealing rings. Background Technology

[0002] The injection tubing is equipped with a piston. During injection, the piston moves forward within the tubing under external force, pushing the liquid or semi-fluid substance, such as medication or adhesive, out of the tubing outlet. A sealing ring is installed on the piston, which fits tightly against the inner wall of the tubing to prevent fluid leakage through the gap between the piston and the tubing during injection, ensuring the accuracy and stability of the injection. The piston and sealing ring are manufactured separately and then assembled.

[0003] Currently, piston and sealing ring assembly is generally done manually, which is costly and prone to damage and inaccurate positioning of the rubber rings during manual placement, resulting in low assembly efficiency. Therefore, this invention provides a fully automated piston and sealing ring assembly device with high assembly efficiency. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Refer to the instruction manual appendix Figures 1-5This utility model provides a fully automatic assembly equipment for pistons and sealing rings, including a processing table 1 and a piston feeding mechanism 2, a sealing ring assembly mechanism 3, a detection mechanism 4, a cleaning mechanism 5, and a discharging mechanism 6 arranged in a ring array. The processing table 1 is provided with a rotating disk 7 on top. The rotating disk 7 is fixed with multiple mounting seats 8 arranged in a ring array on top by bolts. Each mounting seat 8 has two piston placement slots 9 on top. In actual use, a motor is installed between the bottom of the rotating disk 7 and the processing table 1, and the motor can drive the rotating disk 7 to rotate.

[0029] The cleaning mechanism 5 includes a connecting rod 51. A clamping plate 52 is provided on the side of the connecting rod 51 near the feeding mechanism 6. A brush 53 is provided between the clamping plate 52 and the connecting rod 51. A fastening bolt 54 is threadedly connected to the clamping plate 52, and one end of the fastening bolt 54 passes through the clamping plate 52 and contacts the outer wall of the brush 53. Two fastening bolts 55 are threadedly connected to the clamping plate 52. A plurality of threaded holes 56 are provided on the connecting rod 51, and the fastening bolts 55 are threadedly connected to the threaded holes 56.

[0030] The piston feeding mechanism 2 includes a piston vibrating disc 21 and a piston feeding clamp 22, with the piston vibrating disc 21 fixed to the rear end of the processing table 1.

[0031] The sealing ring assembly mechanism 3 includes a sealing ring vibrating plate 31 and a sealing ring feeding clamp 32, wherein the sealing ring vibrating plate 31 is fixed on one side of the processing table 1.

[0032] The detection mechanism 4 includes a linear module 41 fixed to the top of the processing table 1 by bolts. Two capacitive proximity switches 42 are fixedly installed on the top of the slider of the linear module 41. The capacitive proximity switches 42 can detect metal and non-metal objects, thereby enabling the detection of whether there is a sealing ring on the piston.

[0033] The feeding mechanism 6 includes a feeding clamp 61 and a screening hopper 62. The screening hopper 62 is provided with a waste feeding trough 63 and a finished product feeding trough 64. A bracket 65 is fixedly provided on the top of the processing table 1. The piston feeding clamp 22, the sealing ring feeding clamp 32 and the feeding clamp 61 are all fixed on the bracket 65. The screening hopper 62 is fixed on the top of the processing table 1 and is located on one side of the rotating disk 7.

[0034] In actual use, the piston vibrating disc 21 and the piston loading clamp 22 work together to automatically place the piston into the piston placement groove 9 on the mounting base 8. Then, the rotating disc 7 rotates, causing the mounting base 8 to rotate to the bottom of the sealing ring assembly mechanism 3. The sealing ring loading clamp 32 automatically puts the sealing ring on the sealing ring vibrating disc 31 onto the piston. Then, the mounting base 8 with the piston and sealing ring rotates to the front of the detection mechanism 4. The two capacitive proximity switches 42 move closer to the two pistons under the drive of the linear module 41. When the capacitive proximity switch 42 detects the sealing ring on the piston (i.e., it indicates a finished product), the unloading clamp 61 automatically transports the piston to the finished product unloading groove 64. When the capacitive proximity switch 42 does not detect the sealing ring on the piston (i.e., it indicates a defective product), the unloading clamp 61 transfers the defective product to the defective product unloading groove 63. This achieves automatic sorting of finished products and defective products, greatly improving the assembly efficiency of the piston and sealing ring.

[0035] Furthermore, a brush 53 is placed above the rotating disk 7. When there are excess sealing rings on the surface of the mounting base 8, or when the sealing rings break accidentally, the brush 53 can sweep the excess sealing rings onto the rotating disk 7 as the mounting base 8 passes by, preventing the excess sealing rings from remaining on the mounting base 8 and affecting the normal progress of the material feeding process. At the same time, the operator can also loosen the fastening bolts 1 54 and 2 55 to adjust the height and position of the brush 53.

[0036] Refer to the instruction manual appendix Figures 1-5 Limiting pressure plates 33 are provided on both the front and rear sides of the sealing ring vibrating plate 31, and electric push rods 34 are fixed on both limiting pressure plates 33. The electric push rods 34 are fixed to the top of the processing table 1 by bolts.

[0037] When the sealing ring moves within the sealing ring vibrating plate 31, the two limiting pressure plates 33 are positioned above the two sealing rings respectively to prevent the sealing rings from detaching. When the sealing ring feeding fixture 32 delivers the sealing rings, the two limiting pressure plates 33 are automatically moved away from above the sealing rings under the drive of the electric push rod 34 to avoid obstructing the operation of the sealing ring feeding fixture 32.

[0038] Refer to the instruction manual appendix Figures 1-5 Below the screening hopper 62, there are a waste collection box 10 and a finished product collection box 11 fixed together by bolts. Two limiting plates 12 are fixedly provided on the top of the processing table 1 to limit the waste collection box 10 and the finished product collection box 11. A magnet 13 is fixedly embedded in the inner wall of each limiting plate 12. An iron plate 14 is fixedly embedded on the side of the waste collection box 10 and the finished product collection box 11 near the limiting plate 12. The iron plate 14 and the magnet 13 are magnetically attracted to each other for reinforcement.

[0039] The waste collection box 10 and the finished product collection box 11 are limited by two limiting plates 12, and reinforced by the magnetic attraction of magnet 13 and iron plate 14, thereby improving the stability of the waste collection box 10 and the finished product collection box 11.

[0040] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
