Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically to a synchronous belt circulation device. Background Technology

[0002] The utility model disclosed in publication number "CN111992861A" and entitled "A button battery spot welding machine capable of automatic electrode feeding" is a button battery spot welding machine capable of automatic electrode feeding. It includes a positive electrode spot welding device, a negative electrode spot welding device, an automatic feeding device, a positive and negative electrode reversing device, and a battery fixing device. The positive and negative electrode reversing device is provided between the positive electrode spot welding device and the negative electrode spot welding device. The automatic feeding device is provided on the positive electrode spot welding device and the negative electrode spot welding device. The negative electrode spot welding device is arranged opposite to the positive electrode spot welding device. The automatic feeding device includes a loading platform, a unloading platform, a drive motor, a coupling, a drive shaft a, a driven shaft a, a first conveyor belt, a drive shaft b, a driven shaft b, and a second conveyor belt. The loading platform is welded to the first worktable on the side away from the negative electrode welding device. The unloading platform is set on the second worktable on the side away from the positive electrode welding device. Both the first and second worktables are equipped with drive motors. The output ends of the drive motors are connected to the drive shafts a and b via couplings. The drive shaft a and driven shaft a are connected via the first conveyor belt, and the drive shaft b and driven shaft b are connected via the second conveyor belt. Although the first and second conveyor belts can transport button batteries, the lack of a structure to fix the button batteries on the conveyor belts means that the button batteries are prone to shifting or falling due to vibration during transport. This shifting of the button batteries can lead to inaccurate welding and unstable welding quality. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a synchronous belt circulation device with a reasonable structural design, good conveying effect, and beneficial effect on improving welding results.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A synchronous belt circulation device includes a mounting plate, brackets, side brackets, a main circulation wheel, a secondary circulation wheel, a circulation belt, a long guide bar, fixtures, fixture limiting devices, electrode limiting devices, and a power unit. A plurality of the brackets are arranged sequentially along the long side of the mounting plate. The long guide bar is disposed on the brackets. The main circulation wheel and secondary circulation wheel are disposed at both ends of the mounting plate. The circulation belt wraps around the long guide bar, the main circulation wheel, and the secondary circulation wheel. A plurality of fixtures are disposed on the circulation belt. The power unit is disposed on the mounting plate and can drive the main circulation wheel to rotate. The side brackets are disposed on the mounting plate at positions corresponding to the two sides of the long guide bar. The fixture limiting devices and electrode limiting devices are disposed on the corresponding side brackets.

[0006] As a preferred embodiment of this utility model, the upper two sides of the bracket symmetrically protrude upward to form two mounting protrusions, and two long guide bars are correspondingly arranged on the two mounting protrusions. A through groove is formed between the two long guide bars for the circulating belt to pass through, which can ensure that the circulating belt remains stable during operation and is not easily deviated from the track.

[0007] As a preferred embodiment of this utility model, the lower middle part of the bracket is provided with a slot for the circulating belt to pass through, so that the circulating belt can pass through the bracket smoothly and save space.

[0008] In a preferred embodiment of this invention, a slide bar is provided on the mounting plate corresponding to the slot. The slide bar supports the fixture and prevents the circulating belt from sagging due to the weight of the fixture.

[0009] In a preferred embodiment of this invention, the fixture limiting device includes a fixture cylinder, a limiting rod, and limiting claws. The limiting rod is positioned at the middle of the piston rod of the fixture cylinder, and two limiting claws are symmetrically arranged at both ends of the limiting rod, with the distance between the two limiting claws matching the length of the fixture. When positioning is required, as the fixture moves to a predetermined position with the circulating belt, the positioning cylinder extends, and the space between the two limiting claws precisely clamps and positions the fixture.

[0010] In a preferred embodiment of this invention, the electrode limiting device includes a lifting cylinder, a finger cylinder, and limiting blocks. The finger cylinder is mounted on the driving element of the lifting cylinder, and the two limiting blocks are correspondingly mounted on the two fingers of the finger cylinder. When the electrode is placed on the button battery of the fixture, the lifting cylinder drives the finger cylinder to descend to a predetermined height. The finger cylinder controls the two limiting blocks to move closer together, thereby positioning the positive or negative electrode on the button battery, preventing displacement, and ensuring the welding effect.

[0011] As a preferred embodiment of this utility model, the power device includes a base, a stepper motor, an output gear, and a transmission gear. The stepper motor is mounted on the base, the output gear is mounted on the drive shaft of the stepper motor, and the transmission gear is mounted on the axle of the main circulating wheel and meshes with the output gear. Through gear transmission, the operation and transmission of the circulating belt are realized.

[0012] The beneficial effects of this utility model are as follows: The utility model has a reasonable structural design. A fixture is added to the circulating belt to position and support the button battery, providing better stability and effectively preventing the button battery from shifting or falling during transport. When the fixture moves to the required processing position, the positioning cylinder of the fixture limiting device extends, and the fixture is precisely clamped and positioned through the gap between the two limiting claws. When it is necessary to spot weld the positive or negative electrode, the lifting cylinder of the electrode limiting device drives the finger cylinder to descend to the height of the upper surface of the button battery. The finger cylinder controls the two limiting blocks to move closer together, thus positioning the positive or negative electrode on the button battery and preventing shifting, waiting for the spot welding machine to weld. This avoids shifting during welding, effectively improving the accuracy and quality of welding.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0020] See the example. Figures 1 to 6 The synchronous belt circulation device provided in this embodiment includes a mounting plate 1, a bracket 2, a side frame 3, a circulation main wheel 4, a circulation secondary wheel 5, a circulation belt 6, a long guide bar 7, a fixture 8, a fixture limiting device 9, an electrode limiting device 10, and a power device 11.

[0021] Several brackets 2 are arranged sequentially along the long side of the mounting plate 1. The long guide bar 7 is disposed on the bracket 2. The main circulating wheel 4 and the secondary circulating wheel 5 are disposed at both ends of the mounting plate 1. The circulating belt 6 passes around the long guide bar 7, the main circulating wheel 4 and the secondary circulating wheel 5. Several fixtures 8 are disposed on the circulating belt 6.

[0022] See Figure 3 Two mounting protrusions 21 are symmetrically raised on both sides of the upper part of the bracket 2. Two long guide bars 7 are correspondingly set on the two mounting protrusions, and a through groove is formed between the two long guide bars 7 for the circulating belt 6 to pass through, which can ensure that the circulating belt 6 remains stable during operation and is not prone to deviating from the track.

[0023] A slot 22 is provided at the lower middle position of the bracket 2 to allow the circulating belt 6 to pass through smoothly, saving space. Preferably, a slide bar 12 is provided on the mounting plate 1 at the position corresponding to the slot 22. The slide bar 12 supports the fixture 8 and prevents the circulating belt 6 from sagging due to the weight of the fixture 8.

[0024] The power unit 11 is mounted on the mounting plate 1 and can drive the circulating main wheel 4 to rotate. See details... Figure 4 The power unit 11 includes a base 111, a stepper motor 112, an output gear 113, and a transmission gear 114. The stepper motor 112 is mounted on the base 111, the output gear 113 is mounted on the drive shaft of the stepper motor 112, and the transmission gear 114 is mounted on the axle of the circulating main wheel 4 and meshes with the output gear 113. Through gear transmission, the operation and transmission of the circulating belt 6 are realized.

[0025] The side frame 3 is positioned on the mounting plate 1 at positions corresponding to both sides of the long guide strip 7, and the fixture limiting device 9 and electrode limiting device 10 are positioned on the corresponding side frame 3. That is, in actual production, the positions of the fixture limiting device 9 and electrode limiting device 10 are set according to the electrode feeding mechanism and the position of the welding rod. See [link to relevant documentation] Figure 5 The fixture limiting device 9 includes a fixture cylinder 91, a limiting rod 92, and limiting claws 93. The limiting rod 92 is positioned at the middle of the piston rod of the fixture cylinder 91. Two limiting claws 93 are symmetrically arranged at both ends of the limiting rod 92, and the distance between the two limiting claws 93 is adapted to the length of the fixture 8. When positioning is required, as the fixture 8 moves to a predetermined position with the circulating belt 6, the positioning cylinder extends, and the space between the two limiting claws 93 precisely clamps and positions the fixture 8. See also Figure 6The electrode limiting device 10 includes a lifting cylinder 101, a finger cylinder 102, and limiting blocks 103. The finger cylinder 102 is mounted on the driving element of the lifting cylinder 101, and the two limiting blocks 103 are correspondingly mounted on the two fingers of the finger cylinder 102. See also Figure 6 When the electrode is placed on the button cell of the fixture 8, the lifting cylinder 101 drives the finger cylinder 102 to descend to a predetermined height. The finger cylinder 102 controls the two limit blocks 103 to move closer together to position the positive or negative electrode on the button cell, preventing displacement and ensuring the welding effect.

[0026] During operation, button batteries are placed one by one onto fixture 8 on the circulating belt 6 by manual labor or a loading robot. Fixture 8 has recesses that conform to the shape of the button batteries. These recesses position and support the button batteries, effectively preventing them from shifting or falling during transport. When fixture 8 moves with the circulating belt 6 to the position where the electrode needs to be placed, the positioning cylinder of the fixture limiting device 9 extends, clamping and positioning fixture 8 precisely through the gap between the two limiting claws 93. When fixture 8 moves with the circulating belt 6 to the position for spot welding the electrode, the lifting cylinder 101 of the electrode limiting device 10 drives the finger cylinder 102 to descend to the height of the upper surface of the button battery. The finger cylinder 102 controls the two limiting blocks 103 to move closer together, positioning the electrode on the button battery and preventing shifting, thus ensuring the accuracy and quality of the welding process.
