Description

Technical Field

[0001] The present invention belongs to the technical field of liquid injection into a contact lens assembly cup, and specifically relates to a melt-bonded mold liquid injection device for a contact lens assembly cup. Background Art

[0002] Since contact lenses are more convenient to use than general ear-hanging glasses, they are widely favored by users. Generally, the packaging box of disposable contact lenses (such as monthly, weekly or daily disposable contact lenses) is composed of a box body formed by plastic injection molding and an aluminum foil covering the box body. The box body has a concave cup, which can be used to accommodate the contact lenses and the sterile solution used to protect the contact lenses. The aluminum foil can be used to seal the concave cup to prevent the contact lenses in the concave cup from being contaminated by foreign substances. When the user wants to take out the contact lenses, the aluminum foil can be torn off to reveal the contact lenses for use.

[0003] At present, contact lens packaging boxes are usually sold in the form of connecting in a string. The contact lenses need to be placed in a special assembly cup, and then a certain amount of physiological saline is injected and then covered with aluminum foil for sealing. Multiple boxes are arranged in a row, and multiple aluminum foils are respectively covered on the multiple boxes.

[0004] Since the lenses of contact lenses need to be quality inspected one by one before packaging, after the quality inspection is completed, the contact lenses will be placed in the assembly cups that need to be packaged one by one. The material of the assembly cups is PP material. The assembly cups are pre-produced by injection molding, but in order to adapt to various contact lenses with different packaging quantities, the assembly cups are individually injection molded. After the injection molding is completed, different numbers of assembly cups are hot-melt connected side by side according to needs to obtain a row of several assembly cups connected as one. After the welding is completed, liquid needs to be injected inside to facilitate the subsequent loading of contact lenses to keep them moist and prevent adhesion.

[0005] However, the existing assembly cup welding is done manually by arranging the required number of assembly cups, placing them in a dissolving device to complete the connection, and then manually placing the connected assembly cups in a liquid injection machine for liquid injection. Since the structure of the assembly cups themselves and the number of required side-by-side connections are not constant, the transportation and placement of the above steps are almost all done manually.

[0006] Therefore, in order to increase production efficiency, reduce production risks and ensure production quality, a set of automated devices is needed to improve production efficiency in an integrated manner. Utility Model Content

[0007] In order to solve the above problems, this paper proposes a melting mold injection device for contact lens assembly cups. The melting mold injection device is arranged above the workbench. The melting mold injection device includes a melting machine and a injection machine. The middle part of the workbench is symmetrically provided with a melting machine and a injection machine in the front and back directions. A transverse conveyor belt is arranged transversely between the melting machine and the injection machine. A material dividing assembly is arranged at the left end of the transverse conveyor belt, and a material distribution assembly is arranged at the right end of the longitudinal conveyor belt. The material distribution assembly includes a longitudinal material rack conveyor belt and a material dividing conveyor. The material distribution assembly includes a multi-axis mechanical arm and an iron plate conveyor belt. The longitudinal material rack conveyor belt is provided with a full material rack area, a feeding area and an empty material rack area from top to bottom. A material distribution conveyor is arranged horizontally on the upper right side of the feeding area, and the right end of the material distribution conveyor is arranged above the transverse conveyor belt. An iron plate conveyor belt is arranged on the front side of the outer side of the right end of the transverse conveyor belt, and a multi-axis robotic arm is arranged on the rear side of the iron plate conveyor belt. By integrating the original welding, liquid injection and material distribution devices of the contact lens assembly cup into a complete set of automated devices, production can be completed by manually putting in or taking out the material rack supporting the assembly cup and the completed iron plate at the inlet and outlet ends, which greatly reduces the labor cost and also reduces the floor space required for the overall equipment. Full automation can also minimize the personal safety problems that may arise in the welding step, thereby ensuring production safety.

[0008] The workbench is in the shape of a horizontal rectangular table top, with a longitudinal material rack conveyor belt longitudinally embedded in the left end of the workbench, an iron plate conveyor belt transversely embedded in the front right end of the workbench, a manual position is provided on the outer side of the left end of the workbench, and a transverse conveyor belt is transversely provided between the longitudinal material rack conveyor belt and the iron plate conveyor belt. Through the transverse rectangular workbench, it is possible to conveniently realize the layout of automated equipment from left to right, achieve the effect of feeding at the left end and discharging at the right end, facilitate the operation of employees at both ends and the front and rear sealing on both sides of the middle, and ensure safe operation.

[0009] Both the welding machine and the liquid injection machine are desktop devices, and both are equipped with front and rear longitudinal moving components. The operating ports of the welding machine and the liquid injection machine are opposite to each other front and back. The horizontal conveyor belt between the welding machine and the liquid injection machine is arranged below the operating port of the welding machine. By arranging the welding machine and the liquid injection machine on both sides in desktop style, the two steps of welding and liquid injection can be realized, and the volume of the overall device can be reduced, the floor space can be reduced, the production line layout can be optimized, and it is also convenient to realize segmented production without setting additional limit mechanisms on the horizontal conveyor belt.

[0010] The longitudinal material rack conveyor belt is a wide-body longitudinal conveyor belt, which circulates from back to front. A row of racks is arranged horizontally on the top of the longitudinal material rack conveyor belt. The width of the longitudinal material rack conveyor belt is greater than the length of the row of racks. A material dividing conveyor is arranged horizontally across the right side of the middle of the longitudinal material rack conveyor belt. The longitudinal material rack conveyor belt can be used to transport the rows of materials for preventing assembly cups in different areas, thereby distinguishing the racks for full materials, taking materials and empty materials, achieving the effect of input on one side and output on the other side, facilitating the operation of personnel and improving efficiency.

[0011] The material distribution conveyor is a horizontal single-row grouping material collection conveyor. A combined clamp is provided at the left end of the material distribution conveyor, and a limited material distribution fence is provided at the right end of the material distribution conveyor. The combined clamp moves horizontally left and right and up and down below the material distribution conveyor. A horizontal conveyor belt is provided below the material distribution fence, and the material distribution fence moves up and down above the horizontal conveyor belt. The required number of assembly cups are clamped and taken out from the rack through the material distribution conveyor, thereby realizing the grouping and material distribution of the assembly cups. The material distribution fence can also be used to realize the grouped assembly cups entering the melting machine and the injection machine in batches for dissolution and injection, thereby completing simplified and convenient production.

[0012] The transverse conveyor belt is a transverse single-row assembly cup limiting conveyor belt. Assembly cup limiting edges are provided on both sides of the transverse conveyor belt. The transverse conveyor belt crosses between the welding machine and the liquid injection machine. A multi-axis mechanical arm is provided on the outer side of the right end of the transverse conveyor belt. An iron plate conveyor belt is provided on the front side of the right end of the transverse conveyor belt. The grouped assembly cups can be stably moved in production through the transverse conveyor belt, which ensures the stability and limitation of the movement, prevents the components of the assembly cups from offsetting and displacing, and affects the welding effect.

[0013] The iron plate conveyor belt is a combined conveyor belt, which includes two mutually transversely parallel inlet and outlet conveyor belts and a longitudinally vertical push conveyor belt. The inlet and outlet conveyor belts are mutually transversely parallel and are arranged on the front side of the workbench. The left ends of the two inlet and outlet conveyor belts are longitudinally connected and conductively provided with a push conveyor belt. The rear end of the push conveyor belt faces the multi-axis robotic arm. The multi-axis robotic arm is a multi-axis discharging and clamping robotic arm. The top-view rotation range of the multi-axis robotic arm is the complete cloth iron plate above the left end of the iron plate conveyor belt. The iron plate of the assembly cup combination can be transferred and transported through the cooperation of the iron plate conveyor belt and the multi-axis robotic arm, and it is also linked with the multi-axis robotic arm to directly move out after the iron plate is full to complete the production assembly.

[0014] Beneficial effects:

[0015] By integrating the original contact lens assembly cup welding, liquid injection and material distribution devices into a complete automated device, production can be completed by manually inserting or removing the material rack supporting the assembly cup and the completed iron tray at the input and output ends, which greatly reduces labor costs and also reduces the floor space required for the overall equipment. Full automation can also minimize the personal safety issues that may arise in the welding step and ensure production safety.

[0016] Through the horizontal rectangular workbench, the automated equipment can be easily arranged from left to right, achieving the effect of feeding at the left end and discharging at the right end, which is convenient for employees to operate at both ends and the front and rear sealing on both sides of the middle to ensure safe operation.

[0017] By placing the welding machine and the liquid injection machine on both sides, the two steps of welding and liquid injection can be realized, and the volume of the overall device can be reduced, the floor space can be reduced, the production line layout can be optimized, and it is also convenient to realize segmented production without setting additional limiting mechanisms on the transverse conveyor belt.

[0018] The longitudinal material rack conveyor belt can be used to transport the rows of materials for preventing assembly cups in different areas, so that the racks for full materials, taking materials and empty materials can be distinguished, achieving the effect of one-side entry and one-side output, which is convenient for personnel operation and improves efficiency.

[0019] The required number of assembly cups are taken out from the rack by the material dividing conveyor, so that the assembly cups are divided into groups. The material dividing fences can also be used to feed the divided assembly cups into the melting machine and the liquid injection machine in batches for dissolution and liquid injection, so as to complete simplified and convenient production.

[0020] The transverse conveyor belt can be used to stably move the grouped assembly cups during production, thereby ensuring the stability and position limitation of the movement and preventing the components of the assembly cups from offsetting and shifting, thereby affecting the welding effect.
