Description
Technical Field
[0001] This utility model belongs to the field of packaging equipment technology, specifically relating to a disc production line for welding and packaging bottle products. Background Technology
[0002] Ultrasonic welding technology is widely used in many industries, including the cosmetics industry. High-quality cosmetic casings not only need to have a good visual effect but also need to ensure sealing and durability. Ultrasonic welding can achieve seamless welding, resulting in a smooth and flat surface without excess welding marks, ensuring a beautiful and flawless product appearance. Currently, in bottle production workshops, ultrasonic welding is a separate production process. Workers pass assembled bottles and caps one by one through an ultrasonic welding machine to complete the sealing welding, and then collect the products. The drawback of this processing method is that it is highly dependent on manual operation, requiring manual identification of good and bad products. It lacks a precise inspection mechanism, making it prone to errors and omissions, and is not conducive to finished product management. In addition, for bottles with more stringent sealing requirements, it is necessary to add components such as bottle stoppers inside the bottle, which necessitates setting up a separate production line for pressing in the inner stoppers. If the bottle sealing process is divided into multiple separate steps, not only is the processing efficiency very low, but the number of processing errors will also increase significantly. Therefore, it is necessary to improve the existing processing equipment. Utility Model Content
[0003] To address the aforementioned problems and technical needs, this utility model provides a disc production line for welding and packaging bottle products. The disc production line is used for bottle packaging, and various processing equipment can be arranged around the disc production line, enabling the production line to perform multiple processing tasks simultaneously. This improves the efficiency of ultrasonic welding, reduces reliance on manual labor, and automates the packaging process of bottle workpieces.
[0004] The technical solution of this utility model is as follows: A disc production line for welding and packaging bottle products includes a machine base, a turntable, fixtures, a feeding conveyor line, welding machine one, welding machine two, and a transfer mechanism. A turntable is located in the center of the machine base, and multiple fixtures are distributed at equal angles around the center of the turntable. Each fixture has two workpiece slots. The turntable drives the fixtures to rotate intermittently, with each rotation being the angle between the adjacent fixture and the center of the turntable. Multiple workstations are arranged around the turntable on the machine base, each workstation corresponding to one fixture. Each rotation of a fixture moves it from one workstation to the next. The feeding conveyor line extends from outside the machine base onto the machine base, and the workstation corresponding to the end of the feeding conveyor line is the feeding workstation. The feeding workstation places two workpieces into the workpiece slots of the fixtures at a time. The fixtures at the feeding workstation move towards... The workpiece then rotates sequentially through a pre-pressing station, a first welding station, an empty space, and a second welding station. The pre-pressing station pre-presses the workpiece. The first welding station is equipped with a welding machine, and a transfer mechanism is provided between the welding machine and the corresponding fixture. The second welding station is equipped with a welding machine, and the same transfer mechanism is provided between the welding machine and the corresponding fixture. The rotary cylinder in the transfer mechanism rotates to place the unwelded workpiece from the fixture into the welding machine for welding, while simultaneously removing the welded workpiece and placing it back into the fixture. Welding machine one welds the workpiece in the workpiece slot on the left side of the fixture, and welding machine two welds the workpiece in the workpiece slot on the right side of the fixture. The welding time for the workpieces in the two workpiece slots in the same fixture is not the same. Empty space 1 provides space for the transfer mechanism to rotate.
[0005] Furthermore, the transfer mechanism includes a transfer bracket, a rotary cylinder, a transfer beam, and pneumatic grippers. The transfer bracket is a vertical bracket, with a rotary cylinder at its front end. The rotary cylinder is suspended between the fixture and the welding machine and can be freely adjusted in height and extension. A transfer beam is connected below the rotary cylinder, and a pneumatic gripper is provided at each end of the transfer beam. The rotary cylinder drives the transfer beam to rotate, and the pneumatic grippers at both ends of the rotary cylinder simultaneously grip the workpieces on the fixture and the welding machine. Then, the rotation swaps the positions of the two workpieces, completing the loading of the workpiece to be pressed and the unloading of the workpiece after welding.
[0006] Furthermore, the loading station is also equipped with a loading assembly, which includes a loading bracket, a pushing cylinder, a lifting cylinder, and loading grippers. The loading bracket is vertically mounted on the machine platform, and a horizontal pushing cylinder is provided on the loading bracket. The pushing cylinder is connected to the lifting cylinder, and two loading grippers are provided at the bottom of the lifting cylinder. The loading grippers pick up the workpieces at the end of the loading conveyor line and place the two workpieces into the workpiece slots of the fixture at the same time.
[0007] Furthermore, the pre-pressing station is equipped with a pressing mechanism, which includes a vertical support and pressing terminals. The vertical support is fixedly mounted on the machine base, and two pressing terminals are connected to the front end of the vertical support. The pressing terminals can move vertically to perform pre-pressing operations on the two workpieces on the fixture.
[0008] Furthermore, as the turntable rotates backward, the fixture corresponding to the second welding station will sequentially pass through the empty position two, the inner plug loading station, the inner plug pressing station, and the height inspection station. The inner plug loading station performs the inner plug loading operation on the workpiece, the inner plug pressing station performs the pressing operation on the inner plug on the workpiece, and the height inspection station performs the height inspection on the workpiece.
[0009] Furthermore, the fixture passes sequentially from the height inspection station to the good product unloading station, the defective product unloading station, and the empty space detection station. The good product unloading station is equipped with a good product unloading mechanism, which picks up the good workpieces from the fixture and unloads them. The defective product unloading station is equipped with a defective product unloading mechanism, which picks up the defective workpieces from the fixture and unloads them.
[0010] Furthermore, the empty space detection station is equipped with a dual-head sensor, which has two sensing claws. The sensing claws move up and down above the fixture and can sense the placement of the workpieces in the two workpiece slots on the fixture.
[0011] Furthermore, the empty space detection station is set adjacent to the loading station, and the fixture that has been detected by the dual-head sensor returns to the loading station.
[0012] The beneficial effects of this utility model are as follows: 1) Two sets of welding machines are set around the turntable to perform ultrasonic welding on the workpieces on the left and right sides of the fixture, respectively. The workpieces on both sides are welded at different stations. In this way, each fixture can carry two workpieces, and processing two workpieces at once can improve processing efficiency and increase production capacity; 2) The transfer mechanism can simultaneously unload the previously welded workpiece and load the workpiece to be welded. The two workpieces share a fixture at different times, eliminating the need for additional accommodating fixtures. This meets the requirements for workpiece bearing and transfer, and the fixture is not idle during processing, thus improving the utilization rate of the fixture; 3) The disc-shaped production line can perform multiple production tasks simultaneously. The disc-shaped production line can shorten the distance between each station, reduce waiting time during production, and facilitate intelligent management of the production line, improving production efficiency. At the same time, the compact arrangement of each device can reduce the space occupied. Attached Figure Description

Detailed Implementation
[0020] The present invention will now be further described with reference to the accompanying drawings and embodiments.
[0021] like Figure 1-6 The diagram shows a disc production line for welding and packaging bottle products according to this utility model. It includes a machine base 1, a turntable 2, fixtures 21, a feeding conveyor line 3, a welding machine 6, a welding machine 7, and a transfer mechanism 8. The turntable 2 is located in the middle of the machine base 1. Multiple fixtures 21 are distributed around the center of the turntable 2 at equal angles. Each fixture 21 has two workpiece slots 211. The turntable 2 drives the fixtures 21 to rotate intermittently. The angle through which each rotation passes is the angle between the adjacent fixture 21 and the center of the turntable 2. Multiple workstations are arranged around the turntable 2 on the machine base 1. Each workstation corresponds to a fixture. Each time the fixture 21 rotates, it moves from the previous workstation to the next workstation. The feeding conveyor line 3 extends from the outside of the machine base to the machine base 1. The workstation corresponding to the end of the feeding conveyor line 3 is the feeding workstation 101. The feeding workstation 101 places two workpieces into the workpiece slots 211 of the fixture at a time.
[0022] The loading station 101 is also equipped with a loading component 4, which includes a loading bracket 41, a pushing cylinder 42, a lifting cylinder 43, and loading grippers 44. The loading bracket 41 is vertically installed on the machine base 1. The loading bracket 41 is equipped with a horizontal pushing cylinder 42. The pushing cylinder 42 is connected to the lifting cylinder 43. The bottom of the lifting cylinder 43 is equipped with two loading grippers 44. The loading grippers 44 clamp the workpiece at the end of the loading conveyor line 3 and place the two workpieces into the workpiece slot 211 of the fixture 21 at the same time.
[0023] The fixture 21 on the loading station 101 rotates backward and passes sequentially through the pre-pressing station 102, the first welding station 103, the empty space 104, and the second welding station 105. The pre-pressing station 102 pre-presses the workpiece. The first welding station 103 is equipped with a welding machine 6. A transfer mechanism 8 is provided between the welding machine 6 and the corresponding fixture 21. The second welding station 105 is equipped with a welding machine 7. The welding machine 7 and the corresponding fixture 21 are provided with the same transfer mechanism 8. The rotary cylinder in the transfer mechanism 8 rotates to put the unwelded workpiece on the fixture into the welding machine for welding. At the same time, the welded workpiece is taken away and put into the fixture. The welding machine 6 welds the workpiece in the workpiece slot 211 on the left side of the fixture, and the welding machine 7 welds the workpiece in the workpiece slot 211 on the right side of the fixture. The welding time of the workpieces in the two workpiece slots 211 in the same fixture 21 is not the same. The empty space 104 leaves space for the transfer mechanism 8 to rotate.
[0024] The pre-pressing station 102 is equipped with a pressing mechanism 5, which includes a vertical support 51 and pressing terminals 52. The vertical support 51 is fixedly mounted on the machine base 1, and two pressing terminals 52 are connected to the front end of the vertical support 51. The pressing terminals 52 can move vertically to perform pre-pressing operations on the two workpieces on the fixture 21.
[0025] The transfer mechanism 8 includes a transfer bracket 81, a rotary cylinder 82, a transfer beam 83, and pneumatic grippers 84. The transfer bracket 81 is a vertical bracket, and a rotary cylinder 82 is provided at the front end of the transfer bracket 81. The rotary cylinder 82 is suspended between the fixture 21 and the welding machine. The rotary cylinder 82 can be freely adjusted in height and extension. The transfer beam 83 is connected below the rotary cylinder 82. A pneumatic gripper 84 is provided at each end of the transfer beam 83. The rotary cylinder 82 drives the transfer beam 83 to rotate. The pneumatic grippers 84 at both ends of the rotary cylinder 82 simultaneously grip the workpieces on the fixture 21 and the welding machine. Then, the two workpieces are rotated to switch positions, thus completing the loading of the workpiece to be pressed and the unloading of the workpiece after welding.
[0026] As the turntable 2 rotates backward, the fixture 21 corresponding to the second welding station 105 will sequentially pass through the empty space 106, the inner plug loading station 107, the inner plug pressing station 108, and the height inspection station 109. The inner plug loading station 107 performs an inner plug loading operation on the workpiece, the inner plug pressing station 108 performs a pressing operation on the inner plug on the workpiece, and the height inspection station 109 performs a height inspection on the workpiece. The fixture 21 passes sequentially from the height inspection station to the good product unloading station 110, the defective product unloading station 111, and the empty space detection station 112. The good product unloading station 110 is equipped with a good product unloading mechanism (not shown in the figure), which clamps the good workpiece on the fixture for unloading. The defective product unloading station 111 is equipped with a defective product unloading mechanism (not shown in the figure), which clamps the defective workpiece on the fixture for unloading.
[0027] The empty space detection station 112 is equipped with a dual-head sensor 9, which has two sensing claws 91. The sensing claws 91 move up and down above the fixture and can sense the placement of workpieces in the two workpiece slots 211 on the fixture 21. The empty space detection station 112 is located adjacent to the loading station. After the fixture is detected by the dual-head sensor 9, it returns to the loading station 101.
[0028] The operation process of this utility model:
[0029] The assembled workpieces are manually placed on the feeding conveyor line 3. At the end of the feeding conveyor line 3, the feeding component 4 places the two workpieces at the end into the corresponding fixtures at the feeding station 101. The turntable 2 rotates, and the pressing mechanism 5 at the pre-pressing station pre-presses the workpieces. The pressing terminal 52 presses the workpieces to the bottom of the fixture, while simultaneously checking for any missing products. The turntable 2 rotates, and the transfer mechanism 8 transfers the workpieces from the left workpiece slot to the welding machine 6. At the same time, the welded workpieces are returned to the left workpiece slot, and the welding machine 6 performs ultrasonic welding on the workpieces. The turntable 2 rotates twice in succession, moving the fixture to the second welding station 105. The welding machine 7 performs ultrasonic welding on the workpieces in the right workpiece slot. The turntable 2 rotates the fixture sequentially to the inner... The workpiece is filled with inner plugs at the loading station 107, the inner plug pressing station 108, and the height inspection station 109. The height inspection station 109 can detect whether an inner plug is missing. Based on the detection results of the height inspection station 109, good products are unloaded at the good product unloading station 110, and defective products are unloaded at the defective product unloading station 111. After unloading, the fixture 21 should be kept in an unloaded state. The turntable 2 rotates the fixture to the empty position detection station 112. The two sensing claws 91 of the dual-head sensor 9 can detect the two workpiece slots to determine whether they are in an unloaded state. After confirming that they are unloaded, the turntable 2 rotates the fixture 21 back to the loading station 101. The unloaded fixture 21 then receives the workpieces transferred by the loading conveyor line 3.
[0030] The above descriptions are merely several preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations and substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
