Description

Technical Field

[0001] This utility model relates to the field of magnetic material packaging, specifically to a conveyor belt for magnetic packaging. Background Technology

[0002] In the production process, finished magnets need to be packaged for storage and transportation. The produced magnets are moved to the packaging station via conveyor belt for manual packaging or automatic packaging equipment packaging. Because magnets are easily attracted by magnetism and stack, it makes quality inspection of finished magnets by manual or quality inspection equipment difficult. It also makes sorting and packaging by manual or packaging equipment difficult, affecting the packaging efficiency of magnets. In addition, stacked magnets can easily scratch the surface of the magnets, affecting the pass rate of finished products. Utility Model Content

[0003] The purpose of this invention is to provide a conveyor belt for packaging magnets. This conveyor belt uses a magnetic attraction mechanism to magnetically fix finished magnet products, so that each finished magnet product is separated from each other and the probability of adjacent finished magnet products stacking due to magnetic contact is reduced, thereby improving the packaging efficiency of finished magnet products.

[0004] The technical solution adopted by this utility model to solve the above problems is:

[0005] A conveyor belt for packaging magnets includes a support frame, a synchronous belt, and a drive mechanism. The synchronous belt is driven to rotate on the support frame by the drive mechanism. Several magnetic attraction mechanisms capable of magnetically attracting and fixing finished magnets are arranged at equal intervals on the synchronous belt.

The electromagnet is fixed on the inner side of the synchronous belt. Conductive contacts are respectively provided on the front and rear ends of the electromagnet, and the two terminals of the electromagnet are respectively connected to the two conductive contacts. Two conductive strips are provided and are respectively fixed on the brackets on the front and rear sides of the synchronous belt. The two conductive contacts are in contact with the two conductive strips respectively, and the two conductive strips are respectively electrically connected to the positive and negative poles of the DC power supply.

[0007] In the above technical solution, preferably, the magnetic poles of the adjacent electromagnets are opposite.

[0008] In the above technical solution, preferably, the driving mechanism includes a motor and four synchronous pulleys, wherein two synchronous pulleys are fixed coaxially front to back and are driven to rotate by the motor and are arranged in the left end of the bracket, and the other two synchronous pulleys are fixed coaxially front to back and are rotatably arranged in the right end of the bracket. The synchronous belt is sleeved on the four synchronous pulleys, and the distance between the two coaxially fixed synchronous pulleys is greater than the front to back width of the electromagnet.

[0009] In the above technical solution, preferably, the conductive strip is disposed on the synchronous belt at the contact point with the synchronous pulley and on the front and rear sides of the synchronous belt located on the upper side of the synchronous pulley.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figures 1-5 This embodiment provides a conveyor belt for magnet packaging, including a support 1, a synchronous belt 2, and a drive mechanism 3. The synchronous belt 2 is driven to rotate on the support 1 by the drive mechanism 3. Several magnetic attraction mechanisms 4, which can magnetically attract and fix finished magnets, are arranged at equal intervals on the synchronous belt 2.

[0022] This invention aligns the output port of the finished magnet with the left end of the synchronous belt 2, allowing the finished magnets to be output one by one onto the synchronous belt 2. The drive mechanism 3 drives the synchronous belt 2 to rotate at a speed that matches the output speed of the finished magnets, enabling each finished magnet to be placed close to each magnetic attraction mechanism 4. The magnetic attraction mechanism 4 then magnetically holds the finished magnets in place, separating each finished magnet from the others and reducing the probability of adjacent finished magnets stacking due to magnetic contact. This facilitates manual inspection or quality inspection equipment can be placed next to the synchronous belt 2 to inspect each finished magnet individually. It also facilitates manual or packaging equipment sorting and packaging, improving the packaging efficiency of the finished magnets and reducing the probability of scratching the surface of the finished magnets due to stacking, thus increasing the pass rate of the finished magnets.

[0023] See Figure 2 , Figure 3 The magnetic attraction mechanism 4 includes an electromagnet 41 and conductive strips 42. The electromagnet 41 is fixed on the inner side of the synchronous belt 2. Conductive contacts 43 are respectively provided on the front and rear ends of the electromagnet 41, and the two terminals of the electromagnet 41 are respectively connected to the two conductive contacts. Two conductive strips 42 are provided and are respectively fixed on the brackets 1 on the front and rear sides of the synchronous belt 2. The two conductive contacts 43 are in contact with the two conductive strips 42 respectively, and the two conductive strips 42 are respectively electrically connected to the positive and negative poles of the DC power supply.

[0024] The strength of the magnetism of electromagnet 41 is controlled by adjusting the current of the DC power supply, which makes it easy to adapt to magnet products with different magnetic properties. If the magnet product has a strong magnetism, the current of the DC power supply is increased to enhance the magnetism of electromagnet 41, thereby strengthening the fixation of the magnet product and reducing the risk of stacking adjacent magnet products. If the magnet product has a weak magnetism, the current is reduced to save energy and thus reduce production costs.

[0025] The adjacent electromagnets 41 have opposite magnetic poles.

[0026] In this invention, by flipping adjacent electromagnets 41 upside down, or by swapping the electrical connection positions of the two terminals of adjacent electromagnets 41 with the two conductive contacts 43, the magnetic poles of adjacent electromagnets 41 are opposite after the electromagnets 41 are energized.

[0027] Since the finished magnet and electromagnet 41 are fixed by the attraction of opposite magnetic poles, when the magnetic poles of adjacent electromagnets 41 are opposite, the magnetic poles of adjacent finished magnets are also opposite. Thus, a local reverse magnetic field is formed between adjacent electromagnets 41 and adjacent finished magnets to cancel the magnetic attraction force, reducing the probability of adjacent finished magnets attracting each other and stacking.

[0028] See Figure 1 , Figure 5 The drive mechanism 3 includes a motor 31 and four synchronous pulleys 32. Two of the synchronous pulleys 32 are fixed coaxially and driven to rotate by the motor 31 and are located inside the left end of the bracket 1. The other two synchronous pulleys 32 are fixed coaxially and rotated inside the right end of the bracket 1. The synchronous belt 2 is sleeved on the four synchronous pulleys 32.

[0029] Synchronous pulley 32 and synchronous belt 2 have the advantages of stable transmission and high precision, making it easy to control the rotation speed of synchronous belt 2 to match the output speed of the finished magnet, thereby ensuring that each finished magnet can be placed more accurately in the position of magnetic attraction mechanism 4.

[0030] The distance between the two synchronous pulleys 32 fixed on the same axis is greater than the front and rear width of the electromagnet 41, ensuring that the electromagnet 41 can pass between the two synchronous pulleys 32 and avoids the electromagnet 41 from obstructing the rotation of the synchronous pulleys 32.

[0031] See Figure 2 The conductive strip 42 is disposed on the synchronous belt 2 that is in contact with the synchronous pulley 32 and on the front and rear sides of the synchronous belt 2 located on the upper side of the synchronous pulley 32. Thus, the electromagnet 41 at this position has magnetic attraction when energized, while the electromagnet 41 located on the lower side of the synchronous pulley 32 does not have magnetic attraction when de-energized.

[0032] When the finished magnet is located at the synchronous pulley 32 and above the synchronous pulley 32, it can be fixed by the electromagnet 41. When the finished magnet moves to the lower side of the synchronous pulley 32, the fixing effect of the electromagnet 41 disappears, and the finished magnet falls off the synchronous belt 2 under the action of gravity, which facilitates the next packaging process.

[0033] See Figure 1 , Figure 3 The synchronous belt 2 is composed of multiple chain plates 21 that are hinged to the left and right. The chain plates 21 are made of non-magnetic plastic material. A silicone pad 22 is provided on the upper surface of the chain plate 21, and an anti-slip texture 23 is provided on the upper surface of the silicone pad 22.

[0034] The chain plate 21 is non-magnetic, preventing the finished magnet from magnetically adsorbing onto the chain plate 21 and affecting the adsorption effect of the electromagnet 41. The silicone pad 22 has a cushioning effect, protecting the finished magnet and reducing the probability of damage when the finished magnet is bumped. The anti-slip texture 23 reduces the risk of adjacent finished magnets sliding on the synchronous belt 2 due to magnetic attraction, causing them to stack.

[0035] See Figure 4 The electromagnet 41 is provided with a mounting plate 44. The electromagnet 41 is fixed to the chain plate 21 with screws through the mounting holes 45 on the mounting plate 44. The front and rear ends of the mounting plate 44 are provided with elastic sheets 46, and the conductive contacts 43 are provided on the elastic sheets 46.

[0036] When the conductive contact 43 comes into contact with the conductive strip 42, the elastic sheet 46 undergoes elastic deformation, causing the conductive contact 43 to press against the conductive strip 42. This ensures the stability of the electrical connection between the conductive contact 43 and the conductive strip 42, and reduces the risk that the electromagnet 41 will lose power and lose its fixing effect on the finished magnet due to poor contact between the conductive contact 43 and the conductive strip 42.

[0037] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
