Description

Technical Field

[0001] This utility model belongs to the technical field of welding strip clamping fixtures, and more specifically, relates to a magnetically fixed clamping fixture. Background Technology

[0002] In the battery string production process, tooling is needed to press and position the welding strip. To prevent the tooling from slipping relative to the battery cells during transportation, the friction between the tooling and the conveyor belt needs to be increased. Typically, iron bars are placed inside the adsorption platform, and magnets are placed inside the tooling. When the welding strip moves between the adsorption platform and the tooling, the tooling attracts the platform to press the welding strip. When release is needed, an electromagnet gripper is placed on the upper side of the tooling. When the electromagnet is energized, it attracts the tooling away from the adsorption platform, thus releasing the pressed welding strip. However, this product still has some problems. After the electromagnet is de-energized, the magnetic field of the magnet inside the tooling causes the contact surface to continue attracting the electromagnet, leading to delays in tooling release, causing tooling shifting and bouncing. Furthermore, the magnetic field inside the tooling increases the release time of the gripper, affecting the speed of the equipment. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility device uses a magnetic isolation block to magnetically isolate the magnet placed inside, thus weakening the magnetism when the magnet passes through the fixture's suction block. When the electromagnet gripping assembly is de-energized, it can quickly separate from the fixture, resolving the offset and jumping caused by the rapid release of the fixture during its ascent. Furthermore, this utility device incorporates a shielding component between the electromagnet in the electromagnetic gripping assembly and the magnet located at its lower end. When the magnet is placed inside the fixture's suction block, this shielding component acts as a magnetic isolation block enclosing the magnet, thereby weakening the magnetic field between the magnet and the electromagnet. When the magnet is placed on the suction platform, the fixture's suction block contains an iron block, which indirectly connects the electromagnet and the magnet, further weakening the magnetic field shielding between them.

Detailed Implementation

[0022] Specific Implementation Example 1: Please refer to... Figures 1-5 A magnetically fixed clamping fixture includes an electromagnetic gripping assembly 10, a clamping device 20, a conveyor belt 30, and an adsorption platform 40. The electromagnetic gripping assembly 10 is located above the clamping device 20. Electromagnets are provided on both sides of the lower output end of the electromagnetic gripping assembly 10. The electromagnets are arranged to abut against the sides of the clamping device 20, so as to achieve gripping of the clamping device 20 by energizing and de-energizing the electromagnets.

[0023] There is a gap between the clamping device 20 and the middle of the electromagnetic gripping assembly 10. The clamping device 20 includes a tooling adsorption assembly 21, a tooling body 22, and a pressure needle part 23. When the electromagnet at the output end of the electromagnetic gripping assembly 10 is energized, the electromagnet and the tooling adsorption assembly 21 in the clamping device 20 are magnetically attracted to each other.

[0024] The tooling adsorption assembly 21 includes a tooling adsorption block 211, a tooling main frame 212, a magnetic isolation block 213, a magnet 214, and a rubber pad 215. The tooling adsorption block 211 is fitted around the outer periphery of the tooling main frame 212, and is detachably connected to both sides of the tooling main frame 212. The tooling main frame 212 is located on both sides of the clamping device 20, and the tooling body 22 is integrally formed with the tooling main frame 212. The tooling adsorption block 211 completely abuts against the wall of the tooling main frame 212. A through-hole is formed in the middle of each part of the tooling main frame 212, with the opening of the hole facing the conveyor belt 30. The magnetic isolation block 213 is located in the hole within the tooling main frame 212, and abuts against the top wall of the hole. The lower end of the magnetic isolation block 213 has multiple grooves, which are matched with multiple magnets 214. The magnetic isolation block 213 is made of magnetic shielding material, preferably low-carbon steel. Magnets 214 are located within the grooves of the magnetic isolation block 213, and the number of magnets 214 matches the number of grooves in the magnetic isolation block 213. A rubber pad 215 is located below the magnets 214 and is sealed to the edge of the tooling main frame 212.

[0025] The fixture body 22 is the main plate of the clamping device 20, and the fixture body 22 is located in the middle of the clamping device 20. The middle of the fixture body 22 is provided with a plurality of evenly arranged pressure pin mounting holes.

[0026] The pressure needle part 23 is located in the middle of the tooling body 22. The pressure needle parts 23 are all embedded in the pressure needle mounting holes. The pressure needle part 23 includes multiple pressure needle components, and the multiple pressure needle components are matched and correspondingly set with the multiple pressure needle mounting holes.

[0027] The conveyor belt 30 is located at the lower end of the clamping device 20, and the clamping device 20 is slidably connected to both sides of the conveyor belt 30.

[0028] The adsorption platform 40 is located at the lower end of the conveyor belt 30, and its end face always abuts against the conveyor belt 30. An iron strip is provided inside the end face of the adsorption platform 40 to generate a magnetic field attraction with the magnet in the pressing device. The iron strip is arranged opposite to the magnet 213.

[0029] Working principle:

[0030] In operation, the electromagnet gripping assembly is first energized, attracting the clamping device with magnetic force and placing it on the belt. After placement, the electromagnet gripping assembly is de-energized and rises away from the clamping device. The adsorption platform is located below the belt, and its built-in iron bars are attracted by the magnetic field generated by the magnet inside the clamping device. The fixture adsorption block on the clamping device contacts the electromagnet gripping assembly, and the magnetic isolation block shields the magnetic field between the electromagnet and the magnet, preventing the fixture adsorption block from being attracted to the electromagnet gripping assembly after it is de-energized.

[0031] Specific Embodiment Two: Unlike Specific Embodiment One, the magnetic isolation block 213 of a magnetic fixing clamping fixture has multiple iron blocks embedded in its groove. These iron blocks match the groove within the magnetic isolation block 213. Preferably, the shielding material of the magnetic isolation block 213 is iron. A magnetic strip is provided on the end face of the adsorption platform 40, and the magnetic strip is fixedly connected to the adsorption platform 40.

[0032] When the magnetic strip is located on the adsorption platform 40, the iron block set inside the tooling adsorption assembly 21 achieves magnetic attraction between the magnet and the clamping device 20, thereby increasing the friction between the clamping device 20 and the conveyor belt 30. At the same time, there is a magnetic isolation block 213 between the electromagnets at the output end of the electromagnetic gripping assembly 10 and the magnetic strip, thereby reducing the gripping and dwell time of the electromagnets on the tooling adsorption assembly 21 and achieving rapid gripping and placement.

[0033] Working principle:

[0034] In this embodiment, when the electromagnet gripping assembly is energized, it uses magnetic force to attract the clamping device, which is then placed on the belt. After placement, the electromagnet gripping assembly is de-energized and rises away from the clamping device. The adsorption platform is located below the belt and has built-in magnetic strips that are attracted by the magnetic field generated by the iron block inside the clamping device. The tooling adsorption block on the clamping device contacts the electromagnet gripping assembly. The tooling adsorption block is unaffected by the magnetic field of the magnet and will not attract the electromagnet gripping assembly after it is de-energized.
