[0040] The magnet blanking assembly 9 includes a magnet bin 91, a blanking plate 92, a second transverse driving component 93 and a blanking pusher 94. The blanking plate 92 is horizontally arranged at the bottom side end of the assembly bracket 7. The magnet bin 91 is vertically arranged at the upper end of the blanking plate 92. The magnet bin 91 is vertically provided with a blanking trough, and a plurality of magnets are vertically arranged in the blanking trough. A pushing groove and a blanking hole are horizontally provided on the blanking plate 92. The blanking hole is horizontally connected to the pushing groove, and the blanking trough is vertically connected to the pushing groove.

[0044] Working principle of embodiment 1:

[0045] In this embodiment, the longitudinal drive component 2 is used to adjust the longitudinal position of the iron shell placement plate 3, and then the first transverse drive component 5 is used to adjust the transverse position of the dispensing device so that the dispensing device is aligned with the iron shell to be dispensed. Then, the first lifting drive component 6 and the second lifting drive component 81 are driven in sequence to adjust the vertical position of the dispensing device so that the dispensing device is close to the iron shell to be dispensed in the vertical direction. After reaching the pre-set position, the dispensing device is used to dispense glue downward. Then, the first transverse drive component 5 is used to adjust the transverse position of the loading and unloading hole of the blanking plate 92 so that the loading and unloading hole is aligned with the iron shell to be dispensed. Then, the first lifting drive component 6 is driven to adjust the vertical position of the loading and unloading hole so that the loading and unloading hole is close to the iron shell to be dispensed in the vertical direction. After reaching the pre-set position, the second transverse drive component 93 is used to drive the blanking pusher 94 to push the magnet to slide along the push groove to above the loading and unloading hole, so that the magnet falls from the loading and unloading hole onto the iron shell, thereby realizing the automatic assembly and unloading of the magnet.

[0046] At the same time, the main body embodiment fixes the dispensing component 8 and the magnet blanking component 9 on the assembly bracket 7, realizing the integrated setting of the equipment used in the two assembly processes of dispensing and magnet blanking, thereby significantly improving the overall integration of the magnet assembly, shortening the distance between the dispensing component 8 and the magnet blanking component 9, and thus also improving the magnet assembly efficiency.

[0047] Example 2, reference Figure 2 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a third lifting drive component 95, a blanking cylinder 96, a first sleeve 97, and a blanking rod 98, which can prevent the magnet from flipping during blanking and improve the magnet blanking effect. Figure 2 As shown, the magnet blanking assembly 9 further includes a third lifting drive component 95, a blanking cylinder 96, a first sleeve 97 made of magnetic material, and a blanking rod 98 made of non-magnetic material;

[0048] The third lifting drive component 95 is fixed to the other side of the assembly bracket 7. The unloading cylinder 96 and the first sleeve 97 are both vertically fixed to the drive output side end of the third lifting drive component 95. The first sleeve 97 is located below the unloading cylinder 96. The piston rod of the unloading cylinder 96 is output downward and is fixedly connected to the unloading rod 98 through the shaft. The unloading rod 98 is slidably connected in the first sleeve 97. The bottom of the first sleeve 97 is located above the unloading hole.

[0049] When the second transverse driving component 93 drives the unloading pusher 94 to push the magnet to slide along the pushing groove to above the unloading hole, the magnet is magnetically connected to the first sleeve 97, and the unloading cylinder 96 drives the unloading rod 98 to push the magnet into the unloading hole.

[0050] Working principle of embodiment 2:

[0051] The third lifting drive component 95 can be a slide cylinder, which is used to drive the unloading cylinder 96, the first sleeve 97, and the unloading rod 98 to move in the vertical direction. When the second horizontal driving component 93 drives the unloading pusher 94 to push the magnet to slide along the pushing groove to above the unloading hole, the magnet may flip over due to the push, affecting normal unloading. The third lifting drive component 95 of the magnet drives the first sleeve 97 to move downward until the bottom of the first sleeve 97 is above the unloading hole. At this time, the magnet is magnetically connected to the first sleeve 97, and then the unloading cylinder 96 drives the unloading rod 98 to move toward, pushing the magnet into the unloading hole, which can effectively avoid flipping of the magnet during unloading, thereby significantly improving the magnet unloading effect.

[0052] Preferably, a longitudinal limiting sleeve 10 made of non-magnetic material is further provided below the blanking hole. The longitudinal limiting sleeve 10 is vertically connected to the blanking hole, and the inner tube shape of the longitudinal limiting sleeve 10 is adapted to the shape of the magnet.

[0053] Specifically, in this embodiment, by providing a longitudinal limiting sleeve 10 below the discharge hole, the longitudinal falling direction of the magnet can be restricted during the magnet discharge process, thereby further improving the discharge stability.

[0054] Preferably, a reinforcing connector 11 is fixed between the longitudinal limiting sleeve 10 and the blanking plate 92 , and the longitudinal limiting sleeve 10 passes through the reinforcing connector 11 and is fixed below the blanking hole.

[0055] Specifically, in this embodiment, by providing the reinforcing connector 11 , the structural stability of the connection between the longitudinal limiting sleeve 10 and the blanking plate 92 is improved.

[0056] Example 3, reference Figure 3 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a sliding assembly, which can prevent the dispensing part of the dispensing device from poking the iron shell and improve the safety of dispensing. Among them, a sliding assembly is provided between the second lifting drive component 81 and the dispensing bracket 82. The sliding assembly includes a bar slide 84 and a dispensing slide 85. The bar slide 84 is longitudinally fixed on the drive output side end of the second lifting drive component 81. The dispensing slide 85 is slidably connected to the bar slide 84. The dispensing bracket 82 is fixedly connected to the side of the dispensing slide 85 away from the bar slide 84.

[0057] Working principle of embodiment 3:

[0058] When the second lifting drive component 81 drives the dispensing part of the dispensing device to descend, if it descends too much and causes the dispensing part to touch the iron shell, the dispensing slide 85 will rise along the strip slide 84, causing the dispensing device to rise in the vertical direction, avoiding excessive contact force between the dispensing parts of the dispensing device, causing damage to the iron shell, thereby improving the safety of dispensing.

[0059] Preferably, a limiting cover plate 12 is detachably provided above the pushing groove.

[0060] Specifically, in this embodiment, by providing a limiting cover plate 12 above the pushing groove, the pushing stability when pushing the magnet is improved.

[0061] Preferably, a bending connector 13 is fixed to the driving output side end of the second transverse driving component 93, and a horizontal bending portion is provided at the side end of the bending connector 13. The blanking pushing member 94 includes an integrally formed pushing portion 941 and a blanking fixing portion 942. The shape of the pushing portion 941 is adapted to the shape of the pushing groove, and the blanking fixing portion 942 is fixed to the upper end of the horizontal bending portion.

[0062] Preferably, a control circuit is provided inside the placement platform 1, and a plurality of control switches are provided on the side end of the placement platform 1. The control circuit electrically connects the control switches, the first transverse drive component 5, the second transverse drive component 93, the first lifting drive component 6, the second lifting drive component 81 and the third lifting drive component 95.

[0063] Specifically, in this embodiment, by setting a control circuit inside the placement platform 1, it is possible to use several control switches to control the operating states of the first horizontal drive component 5, the second horizontal drive component 93, the first lifting drive component 6, the second lifting drive component 81 and the third lifting drive component 95, thereby simplifying the operation.
