Description

Technical Field

[0001] This utility model relates to the field of injection molded bucket handle production technology, specifically a handle assembly mechanism for injection molded bucket handle production. Background Technology

[0002] Injection-molded bucket handles are auxiliary tools used on injection-molded buckets to increase their portability and ease of use. They are typically manufactured from durable polypropylene or polyethylene through an injection molding process, ensuring the handle's strength and stability under load. Their design emphasizes ergonomics, providing a comfortable grip and making them suitable for everyday handling and use. When assembling the handle, bucket body, and accessories, a handle assembly mechanism is used to load the bucket and then assemble it with the handle.

[0003] The existing assembly of injection molded bucket handles typically requires manual handling. A handle is then bent to fit the outer edge of the bucket opening and aligned with the mounting point for snapping or inserting. This manual operation is time-consuming and labor-intensive, resulting in low assembly efficiency and hindering bucket production, thus impacting overall production efficiency. We propose a handle assembly mechanism for injection molded bucket handle production. Utility Model Content

[0004] The purpose of this utility model is to provide a handle assembly mechanism for the production of injection molded bucket handles, so as to solve the problem of time-consuming, labor-intensive and inefficient manual operation mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a handle assembly mechanism for injection molding barrel handle production, comprising a base, a guide rail bracket, a vertically mounted frame, and a pressing bracket on the top of the base, a servo assembly assembly on the top of the guide rail bracket, a loading rod at the power output end of the servo assembly assembly, a loading guide rail fixed to the base on the side wall of the servo assembly assembly, a gripper mechanism on the top of the loading guide rail, a positioning platform fixed to the base on the side wall of the loading guide rail, lower brackets fixed to the base on both sides of the positioning platform, a positioning cylinder on the top of the lower bracket, and a pressing cylinder on the top of the pressing bracket.

[0006] Preferably, the top of the positioning platform is machined with a positioning groove, and a positioning block is provided inside the positioning groove.

[0007] Preferably, the positioning platform has a frame fixed to the base on its rear side, and the top of the frame has an upper bucket servo rail and a lower bucket servo rail.

[0008] Preferably, the upper bucket servo guide rail power output end is provided with a sliding seat, and the upper bucket rotating gripper is fixedly connected to the side wall of the sliding seat.

[0009] Preferably, the power output end of the lower bucket servo guide rail is provided with a vertical guide rail, and the power output end of the vertical guide rail is provided with a suction component.

[0010] Preferably, the pressing cylinder is fitted to the side wall of the positioning platform, and a pressing rod is provided at the power output end of the pressing cylinder.

[0011] Preferably, the power output end of the positioning cylinder is provided with a positioning rod, which is fitted to the side wall of the positioning platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, when the handle is placed on top of the gripper mechanism, the feeding guide rail moves so that the handle fits against the outer edge of the injection molding barrel placed on top of the positioning platform. Then, the servo assembly component moves so that the insertion rod abuts against both ends of the handle, allowing the two ends of the handle to bend against the outer edge of the injection molding barrel. Finally, with the operation of the pressing cylinders on both sides, the pressing rod abuts against both ends of the handle to install it against the installation point of the barrel opening. This allows the handle to be bent and installed against the outer edge of the barrel opening, solving the problem of inconvenience in manually bending handles for installation, improving the installation efficiency of handles, and saving labor costs.

[0014] 2. In this invention, when feeding injection molding barrels, the upper barrel rotating gripper can clamp the inverted injection molding barrel conveyed on the feeding conveyor belt. Then, the upper barrel servo guide rail moves, causing the injection molding barrel of the upper barrel rotating gripper to move and engage with the positioning groove of the positioning platform. Next, the handle, together with the gripper mechanism, moves closer to the outer edge of the injection molding barrel. At the same time, the positioning cylinder on the lower support rises and moves, causing the positioning rod to pop out and contact the outer edge of the injection molding barrel. When the positioning rod engages with the outer edge of the injection molding barrel, it is in a compressed state, resulting in a higher air pressure inside the positioning cylinder. At this time, the air pressure data inside the positioning cylinder is transmitted to the bottom. The controller inside the unit commands the upper barrel rotating gripper to rotate, causing the injection barrel to rotate. When the positioning rod enters the positioning hole on the outer edge of the injection barrel, it extends. At this time, the controller receives data and causes the upper barrel rotating gripper to stop rotating and release the injection barrel. At this point, the handle is fitted to the outer edge of the injection barrel for installation. This allows the upper barrel rotating gripper to position the injection barrel while simultaneously adjusting the rotation of the injection barrel using a positioning cylinder. This avoids the problem of incorrect positioning of the injection barrel, which would prevent the handle from being installed at the outer edge of the barrel opening. This facilitates the assembly and production of injection barrels. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Example

[0021] Please see Figures 1-3The diagram illustrates a handle assembly mechanism for producing injection molded bucket handles. It includes a base 100, which houses a commonly available programmable PLC controller. A guide rail bracket 110, a vertically mounted frame 143, and a pressing bracket 170 are bolted to the top of the base 100. A servo assembly assembly 111 is bolted to the top of the guide rail bracket 110. A commonly available horizontally mounted servo cylinder is mounted on the guide rail bracket 110. This horizontally mounted servo cylinder pushes the loading rod 112 closer to and presses against the handle, bringing the handle close to the injection molded bucket. The servo assembly assembly 111 uses a commonly available vertically mounted servo cylinder, which pushes the loading rod 112 upwards. The power output end of the servo assembly assembly 111 is equipped with the loading rod 112. A side wall of the servo assembly assembly 111 is fixed to the base 100. The loading guide 120 uses a common electric linear guide. The top of the loading guide 120 is equipped with a gripper mechanism 121, which uses a common electric cylinder gripper. When a common robotic arm for picking up material from the handle places the handle on the top of the gripper mechanism 121, it can clamp the handle. The side wall of the loading guide 120 is fitted with a positioning platform 130 fixed to the base 100. The positioning platform 130 is equipped with a lower bracket 160 fixed to the base 100 on both sides. The top of the lower bracket 160 is equipped with a positioning cylinder 161, which uses a common servo cylinder. Its internal operating data is transmitted to the controller to determine the rotation angle of the injection barrel. The top of the pressing bracket 170 is equipped with a pressing cylinder 171, which uses a common servo cylinder.

[0022] Specifically, the top of the positioning platform 130 is machined with a positioning groove 131, and a positioning block 132 is tightly welded inside the positioning groove 131. When the injection molding barrel is installed, the positioning block 132 fits into the inside of the injection molding barrel.

[0023] Furthermore, a frame 143 fixed to the base 100 is provided on the rear side of the positioning platform 130, and an upper bucket servo rail 140 and a lower bucket servo rail 150 are provided on the top of the frame 143.

[0024] Furthermore, the upper bucket servo guide rail 140 is equipped with a sliding seat 141 at its power output end. Both the upper bucket servo guide rail 140 and the lower bucket servo guide rail 150 use commercially available horizontally mounted electric guide rails. The upper bucket rotating gripper 142 is fixedly connected to the side wall of the sliding seat 141. The sliding seat 141 is a commercially available vertically mounted electric guide rail.

[0025] In some embodiments, the bottom of the upper barrel rotating gripper 142 and the bottom of the suction member 152 are provided with commercially available conveyor belt assemblies, which can input and output injection barrels.

[0026] Furthermore, the power output end of the lower barrel servo guide rail 150 is equipped with a vertical guide rail 151. The vertical guide rail 151 uses a common electric guide rail. The power output end of the vertical guide rail 151 is equipped with a suction component 152, which is a common pneumatic suction cup. After the injection barrel is installed, the vertical guide rail 151 moves, causing the suction component 152 to move downwards and suck up the injection barrel. Then it rises, and then the lower barrel servo guide rail 150 moves, driving the injection barrel to the left and placing it on top of the discharge conveyor belt.

[0027] It is worth noting that the press-in cylinder 171 is fitted to the side wall of the positioning platform 130, and a pressing rod is provided at the power output end of the press-in cylinder 171.

[0028] It is worth noting that a positioning rod is provided at the power output end of the positioning cylinder 161, and the positioning rod is engaged with the side wall of the positioning platform 130.

[0029] In addition, all the electrical components and equipment mentioned above use external power sources. The circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0030] Working principle: When the handle is placed on top of the gripper mechanism 121, the feeding guide rail moves, causing the handle to conform to the outer edge of the injection molding barrel mouth placed on top of the positioning platform 130. Then, the servo assembly component 111 operates, causing the insertion rod 112 to abut against both ends of the handle, allowing the two ends of the handle to conform to the outer edge of the injection molding barrel mouth and bend. Finally, the pressing cylinders 171 on both sides operate, causing the pressing rod to abut against both ends of the handle and install it at the mounting point on the outer edge of the barrel mouth, thereby realizing the lifting and lowering of the handle. The handle is installed by bending it to fit the outer edge of the barrel opening, solving the common problem of inconvenience in manually bending the handle during installation, improving installation efficiency and saving labor costs. When loading the injection molded barrel, the upper barrel rotating gripper 142 clamps the inverted injection molded barrel conveyed on the feeding conveyor belt. Then, the upper barrel servo guide rail 140 moves, causing the injection molded barrel in the upper barrel rotating gripper 142 to move and engage with the positioning groove 131 of the positioning platform 130. Then, the handle is fitted... The clamping jaw mechanism 121 approaches the outer edge of the injection molding barrel. Simultaneously, the positioning cylinder 161 on the lower support 160 rises and operates, causing the positioning rod to pop out and contact the outer edge of the injection molding barrel. When the positioning rod engages with the outer edge of the injection molding barrel, it is in a compressed state, resulting in a higher air pressure inside the positioning cylinder 161. At this time, the air pressure data inside the positioning cylinder 161 is transmitted to the controller inside the base 100. The controller commands the upper barrel rotating jaw 142 to rotate, causing the injection molding barrel to rotate. When the positioning rod enters the positioning hole on the outer edge of the injection molding barrel, it extends. At this time, the controller receives the data and causes the upper barrel rotating jaw 142 to stop rotating and release the injection molding barrel. At this time, the handle is attached to the outer edge of the injection molding barrel for installation. Thus, the upper barrel rotating jaw 142 can be used to position the injection molding barrel while the positioning cylinder 161 is used to rotate and adjust the injection molding barrel. This avoids the problem that the installation point on the outer edge of the barrel opening cannot be matched with the handle due to incorrect positioning of the injection molding barrel, and facilitates the assembly and production of the injection molding barrel.
