Description

Technical Field

[0001] This utility model relates to automated assembly equipment for fitness equipment, and more particularly to a fully automatic filling and capping device for fitness equipment counterweights. Background Technology

[0002] In the production of weights for fitness equipment (such as dumbbells and barbell plates), it is common practice to fill the shell with weighting material (such as cement mixture) and then seal it with a cap. Currently, many production lines still rely on manual labor or semi-automated equipment for the capping process after filling, resulting in low efficiency, high labor costs, and poor capping quality consistency. In particular, during the capping process, it is crucial to ensure that the cap is aligned with the weight shell and pressed in smoothly. Improper clamping or pressing can easily lead to cap misalignment, incomplete sealing, or damage to the workpiece. Therefore, there is an urgent need for a fully automated device that can achieve precise gripping and reliable pressing to improve production efficiency and product quality. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned problems and provide a fully automatic filling and capping device for fitness equipment counterweights with a high degree of automation and accurate and reliable capping.

[0004] The technical solution of this utility model is: The fully automatic filling and capping device for fitness equipment counterweights described in this utility model is used to press caps onto counterweights, characterized in that it includes: A conveyor line, wherein an assembly station is defined on the conveyor line; Tooling plate, set on the conveyor line, is used to load counterweights; A lifting mechanism is located below the assembly station and is used to lift the tooling plate. A lateral clamping mechanism is installed next to the assembly station and is used to laterally clamp the counterweight. A capping robot is installed next to the assembly station on the conveyor line, and a clamp is attached to the end of the capping robot. The clamp includes a clamp base, a three-jaw cylinder, and three clamping plates; the three-jaw cylinder is mounted on the clamp base, and its three jaws can open and close radially synchronously; the three clamping plates are respectively mounted on the three jaws, and have arc-shaped clamping parts on their inner sides, and the three together form a circular clamping area for clamping the cover. The three-jaw cylinder has a central push rod coaxially arranged inside, which can move axially independently of the jaws. The lower end of the central push rod is connected to a pressure head.

[0005] Furthermore, in the fully automatic filling and capping equipment for fitness equipment counterweights described in this utility model, the lateral clamping mechanism includes two opposing clamping cylinders. The piston rod end of the clamping cylinder is connected to a U-shaped clamping block. The opening of the U-shaped clamping block faces and is engaged with the upper two sides of the counterweight, which can stably clamp the counterweight from the horizontal direction, effectively counteract the lateral force generated during capping, and prevent the workpiece from shifting or tilting during the pressing process.

[0006] Furthermore, in the fully automatic filling and capping equipment for fitness equipment counterweights described in this utility model, the tooling plate includes: A concave base is used to accommodate the counterweight; At least one guide sleeve is disposed on one side plate of the base; A clamping plate is located inside the cavity of the base; A guide rod extends through the guide sleeve, with one end connected to the clamping plate. An elastic element is sleeved on the guide rod and presses against the side plate of the base and the clamping plate; An adjusting nut is screwed onto the other end of the guide rod.

[0007] The tooling plate ensures the positional stability of the workpiece during conveying and lifting through a "three-sided fixing and one-sided clamping" design; at the same time, the structure has a certain degree of self-adaptability, and can adapt to workpieces of different sizes by adjusting the nuts, making it highly versatile.

[0008] Furthermore, in the fully automatic filling and capping equipment for fitness equipment counterweights described in this utility model, a first blocking cylinder is provided at the assembly station for positioning the tooling plate, which realizes the precise positioning of the tooling plate at the assembly station and provides an accurate spatial position reference for subsequent lifting and capping actions.

[0009] Furthermore, in the fully automatic filling and capping equipment for fitness equipment counterweights described in this utility model, the conveyor line has a double-layer structure, including an upper conveyor line and a lower conveyor line, with the assembly station located on the upper conveyor line; a second blocking cylinder is provided on the lower conveyor line. This structure realizes the cyclical use and diversion of empty and full tooling plates, optimizes the spatial layout of the equipment, makes the material flow more reasonable, and greatly improves the continuity and efficiency of the entire production line.

[0010] Furthermore, in the fully automatic filling and capping equipment for fitness equipment counterweights described in this utility model, the lifting mechanism is a lifting cylinder, which has a simple structure.

[0011] Furthermore, in the fully automatic filling and capping equipment for fitness equipment counterweights described in this utility model, the output end of the capping robot is provided with a lifting screw for installing the clamp, which can finely adjust the height of the clamp.

[0012] The beneficial effects of this utility model are: 1. This utility model, through the coordinated operation of a conveyor line, lifting mechanism, lateral pressing mechanism, capping robot, and its end-effector composite clamp, constitutes a complete fully automatic capping system. It achieves full automation from counterweight conveying, precise positioning, multi-directional pressing, cap gripping to final pressing, significantly improving production efficiency and reducing labor costs. The unique composite clamp, through the coordinated action of radial clamping by a three-jaw cylinder and independent axial pressing by a central push rod, ensures uniform pressure and vertical pressing of the cap, effectively preventing skewing and damage, and improving capping quality and sealing reliability. Meanwhile, the lifting mechanism, lateral pressing mechanism, and tooling plate with elastic pressing function work together to form a stable positioning and clamping system at the capping station, effectively resisting reaction forces during the pressing process and ensuring the accuracy and stability of the assembly process.

[0013] 2. The tooling plate has a clever structural design. Through the cooperation of the concave base and the elastic clamping mechanism on one side, the counterweight is positioned with "three sides fixed and one side tightened". This eliminates the assembly gap between the counterweight and the tooling plate, ensuring that its position is stable during conveying and lifting and will not move. Moreover, it can be adapted to workpieces of different sizes by adjusting the nut, making it highly versatile.

[0014] 3. The equipment of this utility model has a compact layout. The design of the double-layer conveyor line realizes the automatic circulation and empty-full exchange of tooling plates, optimizes the space utilization, and makes the entire process of feeding, assembly and unloading seamlessly connected, which greatly improves the continuity and efficiency of the whole production line.

[0019] The present invention will now be further described with reference to the accompanying drawings: Reference Figure 1 , Figure 2 As shown in the figure, the fully automatic filling and capping equipment for the fitness equipment counterweight block described in this embodiment is used to press the cap 7 onto the counterweight block 8, and includes a conveyor line 1, a tooling plate 2, a lifting cylinder 3, a lateral pressing mechanism, and a capping robot 5.

[0020] The conveyor line 1 has a double-layer structure, including an upper conveyor line 101 and a lower conveyor line 102. An assembly station is defined on the upper conveyor line 101. The tooling plate 2 is mounted on the conveyor line 1 and is used to load the counterweight block 8; the assembly station is provided with a first blocking cylinder 9 for positioning the tooling plate 2, and the lower conveyor line 102 is provided with a second blocking cylinder 10.

[0021] The lifting cylinder 3 is located below the assembly station and is used to lift the tooling plate 2; The lateral clamping mechanism consists of two opposing clamping cylinders 4, respectively positioned on both sides of the assembly station, with a U-shaped clamping block 401 connected to the end of their piston rods. When the cylinders actuate, the openings of the U-shaped clamping blocks 401 face and engage with the upper sides of the counterweight block 8. By increasing the contact area with the workpiece and forming a covering structure, the clamping stability is significantly enhanced, effectively preventing any slight displacement or shaking of the workpiece during the pressing process.

[0022] The capping robot 5 is located next to the assembly station of the conveyor line 1, and its output end is provided with a lifting screw 501 for installing the clamp 6.

[0023] Reference Figure 4 The clamp 6 includes a clamp base 601, a three-jaw cylinder 602, and three clamping plates 603. The three-jaw cylinder 602 is mounted on the clamp base 601, and its three jaws can open and close radially synchronously. The three clamping plates 603 are respectively mounted on the three jaws, and have an arc-shaped clamping part 604 on their inner side. The three clamps together form a circular clamping area for clamping the cover 7. The interior of the three-jaw cylinder 602 is coaxially provided with a central push rod 605 that can move axially independently of the jaws. The lower end of the central push rod 605 is connected to a pressure head 606.

[0024] Reference Figure 3 The tooling plate 2 includes a recessed base 201 for accommodating the counterweight 8, at least one guide sleeve 202, a clamping plate 203, and a guide rod 204. The guide sleeve 202 is disposed on one side plate of the base 201. The clamping plate 203 is located in the inner cavity of the base 201. The guide rod 204 movably passes through the guide sleeve 202, with one end connected to the clamping plate 203 and the other end screwed with an adjusting nut 205. It also includes a spring 206 sleeved on the guide rod 204, which presses against the side plate of the base 201 and the clamping plate 203 to provide preload force for the clamping plate 203.

[0025] The workflow of this utility model is as follows: 1. Loading and conveying: The counterweight 8, which has been filled, is placed into the tooling plate 2 and fixed on three sides and positioned on one side by the clamping plate 203 and the base 201. The tooling plate 2 is conveyed to the assembly station via the upper conveyor line 101.

[0026] 2. Positioning and Lifting: When the tooling plate 2 carrying the counterweight 8 arrives at the assembly station, the first blocking cylinder 9 rises to precisely position it. Subsequently, the lifting cylinder 3 actuates, lifting the entire tooling plate 2, causing it to detach from the conveyor line 1 and rise to the fixed capping height.

[0027] 3. Lateral clamping: After the lifting action is completed, the clamping cylinders 4 on both sides of the assembly station are activated simultaneously, and their piston rods extend to clamp the upper parts of both sides of the counterweight 8 from the horizontal direction, and firmly lock them in the tooling plate 2.

[0028] 4. Capping the lid: Simultaneously, the capping robot 5 moves to the lid feeding area. Its end gripper moves, and the three-jaw cylinder 602 drives the three clamping plates 603 to retract radially, clamping the outer periphery of the lid 7.

[0029] 5. Handling and Pressing: The capping robot 5 carries the cap 7 to a position directly above the fixed counterweight 8. The capping robot 5 moves downwards, initially aligning the cap 7 with the opening on the counterweight 8. Subsequently, the central push rod 605 of the clamp 6 extends downwards, applying vertical downward pressure to the top center of the cap 7 through the pressing head 606, smoothly and vertically pressing it into the opening of the counterweight 8. Throughout this process, the three clamping plates 603 remain in a clamping state, providing a supporting function.

[0030] 6. Reset and Unloading: After pressing into place, the central push rod 605 retracts first, followed by the opening of the three-jaw cylinder 602, releasing the cover 7. Then, the pressing robot 5 repeatedly grips the cover 7 and presses it onto different openings of the counterweight 8 until all openings are closed. The two clamping cylinders 4 retract, releasing the lock on the counterweight 8. Finally, the lifting cylinder 3 drives the descent, placing the tooling plate 2 back onto the upper conveyor line 101. The first blocking cylinder 9 retracts, and the finished product is sent to the next process via the upper conveyor line 101. The unloaded tooling plate 2 returns to the loading area via the lower conveyor line 102, and the cycle repeats.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
