Description

Technical Field

[0001] The utility model relates to the technical field of magnetic block batch detection, in particular to a detection orientation adjustment device of a magnetic detector. Background Art

[0002] Due to its repeatable disassembly and assembly characteristics, magnetic blocks are widely used in consumer fields such as home entertainment, outdoor adventure, and educational toys. The most important process in producing magnetic blocks is to magnetize the block magnetic material. The volume of magnetic blocks in the consumer field is relatively small, and the consistency of the size accuracy of mass-produced magnetic blocks is low. This leads to the fact that during the magnetization stage of the magnetic material, some magnetic materials cannot reach the magnetization saturation state completely and show leakage of magnetism, which is manifested as the defect of insufficient magnetic attraction of the magnetic block. Therefore, an important process in the production process of magnetic blocks is magnetic detection.

[0003] Existing magnetic detection solutions, such as patent document CN113311371A, place a magnet chain composed of multiple magnetic blocks in a magnet chain placement slot of a magnet chain fixing platform, and use a movable guide rail to drive the magnet chain fixing platform to move, so that all the magnetic blocks of the magnet chain pass through the magnetic field sensor in sequence for magnetic detection. However, since the magnetic detection of the prior art is a fixed-direction detection, the detection effect of magnetic blocks of different shapes fluctuates greatly. Utility Model Content

[0006] Furthermore, it includes a locking piece installed on the side of the mounting frame, and a through locking groove is horizontally opened at the lower part of the locking piece. The width of the locking groove is slightly larger than the width of the through groove in the horizontal state of the side wall, so that the through groove can be inserted into the locking groove for magnetic detection.

[0007] Furthermore, the mounting frame is provided with a vertical slot, and the locking member is inserted into the slot to enable the locking member to be installed beside the mounting frame.

[0012] Further, the mounting bracket and the alignment driving device are arranged on the same side of a horizontally arranged transmission channel through which the magnetic block to be detected passes.

[0013] Further, the displacement driving device includes a lateral movement direction and a vertical movement direction.

[0020] The present invention is further described in detail below in conjunction with specific implementation methods.

[0021] The magnetic block batch detection device of this embodiment is as follows Figure 1 and 2 As shown, it includes a horizontal transmission channel for the magnetic blocks to be detected to pass through, and also includes a controller and a loading and shaping conveying device 1, a detection orientation adjustment device 2, a unloading and clamping conveying device 3 and a magnetic block rejection device 4 which are arranged in sequence along the magnetic block transmission direction beside the magnetic block transmission channel. These devices are respectively communicated with the controller of the magnetic block batch detection equipment.

[0022] like Figure 3 As shown, batches of magnetic blocks C are placed into the transmission channel from the starting end S of the magnetic block batch detection device in a mutually attracted state. A removable vertical baffle is provided at the head end of the transmission channel. Before detection, the vertical baffle is removed and the magnetic blocks to be detected are placed. After the batch of magnetic blocks to be detected are placed in the first section of the transmission channel, the vertical baffle is installed to resist the last magnetic block, so that the entire magnetic block queue is compact and not easy to misalign. The loading and shaping conveying device 1 is used to limit and transmit the top and side positions of the batch of magnetic blocks, so that multiple magnetic blocks can continuously pass through the magnetic detector in the detection orientation adjustment device 2 in a neatly connected manner. The magnetic detector is used to detect the magnetism of each magnetic block, and the magnetic data detected by it is transmitted to the controller. The controller is also connected to the display 0 in communication, and the display 0 displays the magnetic data. The unloading and pressing conveying device 3 applies pressure to the passing magnetic block queue from the left and right sides to make the adjacent magnetic blocks tightly connected. The controller identifies unqualified magnetic blocks from the received magnetic data according to the preset program, and sends the in-place signal of the unqualified magnetic blocks to the magnetic block rejection device 4. The magnetic block rejection device 4 is used to act according to the received in-place signal to separate the magnetic block corresponding to the in-place signal from the continuous batch of magnetic blocks. A baffle is provided at a small distance from the end of the transmission channel, and the baffle is tilted in the direction of the transmission channel. The magnetic blocks that have not been separated from the batch of magnetic blocks are removed from the transmission channel from the end E of the magnetic block batch detection device as qualified magnetic blocks, and fall due to gravity or are blocked by the baffle and fall into the discharge trough below the end of the transmission channel.

[0023] The following is a detailed description of the working process of each device of the magnetic block batch detection equipment.

[0024] like Figure 4 and 5As shown, the transmission channel is specifically a U-shaped structure composed of two mutually fitting left and right splicing parts 24 and 25. One of the two splicing parts is a horizontally placed bottom panel for supporting the magnetic block to be detected, and the other is an inverted L-shaped structure. The entire transmission channel is composed of multiple groups of two mutually cooperating splicing parts, and each group is provided with a transverse movement driving device to drive the two splicing parts away from or closer to each other, so as to adjust the width of the transmission channel to adapt to the width of the magnetic block.

[0025] As Figure 3 shown, a detection orientation adjustment device 2 is provided in the middle section of the magnetic block batch detection device. As Figure 5 shown, the detection orientation adjustment device 2 includes a mounting frame and a positioning member 21 installed beside the mounting frame. The mounting frame is used to install the magnetic detector 22. Specifically, the mounting frame is provided with a vertical card slot 212, and the positioning member 21 is inserted into the card slot 212 to install the positioning member 21 beside the mounting frame. The detection orientation adjustment device 2 includes a positioning drive device 26 for driving the magnetic detector 22 to align with the magnetic block C to be detected on the middle transmission channel. The mounting frame and the positioning drive device 26 are both arranged on the same side of the horizontally placed transmission channel for the magnetic block to be detected to pass through. The positioning drive device 26 includes a displacement drive device for driving the mounting frame to move and a fine adjustment slide table for adjusting the detection orientation of the magnetic detector; a through slot 23 capable of rotating around the horizontal axis is provided at the end of the fine adjustment slide table. In the state where the magnetic detector 22 is installed on the mounting frame, the detection head of the magnetic detector 22 is placed in the through slot 23. A through positioning slot 211 is horizontally opened at the lower part of the positioning member 21, and the width of the positioning slot 211 is slightly larger than the width of the through slot 23 in the state where the side wall is horizontally placed, so that the through slot 23 can be inserted into the positioning slot 211 for magnetic detection. The through slot 23 rotates around the horizontal axis to switch the detection head of the magnetic detector 22 between the state where the bottom detection area is blocked by the side wall of the through slot and the state where it is not blocked. In the state where the detection head of the magnetic detector 22 is blocked by the side wall of the through slot from the bottom detection area, the magnetic detector 22 horizontally detects the magnetism of the magnetic block; in the state where the detection head of the magnetic detector 22 is not blocked by the side wall of the through slot from the bottom detection area, the magnetic detector 22 vertically detects the magnetism of the magnetic block.

[0026] Among them, the direction in which the displacement drive device drives the mounting frame to move includes the horizontal movement direction and the vertical movement direction, so as to move the position of the magnetic detector 22 to the corresponding position for horizontal detection and alignment with the magnetic block or the position for vertical detection and alignment with the magnetic block.

[0027] Among them, the fine adjustment slide table includes a rotating device, a swinging member is provided on the rotating device, and a clamp is provided at the end of the swinging member. The clamp clamps the detection head to install the magnetic detector on the fine adjustment slide table. The fine adjustment slide table is specifically a manual fine adjustment micro cross slide table of model E-EIC36.

[0028] The above is only the implementation mode of the present invention, and does not limit the scope of patent protection. Those skilled in the art make non-substantive changes or substitutions based on the present invention, and still fall within the scope of patent protection.
