Description

Technical Field

[0001] This invention belongs to the field of automated machinery technology, and in particular relates to a Hall element coating device. Background Technology

[0002] An electronic water pump mainly consists of a motor and a water pump. The motor drives the water pump to draw water. The motor contains a control board, which is usually connected to the windings of the stator assembly. By controlling the on / off state of different windings of the stator, the direction of the magnetic field is constantly changed, so that the rotor can maintain its original direction and continue to rotate after turning half a revolution. For example, a motor, water pump assembly and vehicle disclosed in patent number CN208971277U, the stator assembly includes a stator frame and a Hall element. The Hall element needs to be installed and fixed on the Hall element mounting seat of the stator frame. In the current production process, the fixation between the Hall element and the stator frame is achieved by manual gluing, which is inefficient. Moreover, after a long time of gluing, the workers are prone to fatigue, which reduces production efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a Hall element adhesive coating device that enables automated adhesive application.

[0004] The objective of this invention can be achieved through the following technical solution: A Hall element coating device includes a rotating disk capable of circumferential rotation. A pre-pressing station, a coating station, and a curing station are sequentially distributed outside the circumference of the rotating disk. A stator frame is placed on the rotating disk, and as the rotating disk rotates, the stator frame moves between the pre-pressing station, the coating station, and the curing station.

[0005] The pre-compression station is equipped with a pre-compression head that can move up and down relative to the rotary table;

[0006] The adhesive application station is equipped with an adhesive dispensing machine that can move vertically up and down.

[0007] The curing station is equipped with an extrusion device and a curing agent spray can. The extrusion device extrudes the spray can nozzle to spray the curing agent onto the Hall element after dispensing.

[0008] In the aforementioned Hall element coating equipment, three mounting blocks are circumferentially distributed on the rotating disk. Each mounting block has a mounting groove with an opening at the top for mounting the stator frame. A positioning block is fixedly installed on the side of the mounting block. Multiple positioning posts are provided on the side of the stator frame facing the welding pin fixing frame. The positioning block has a positioning groove with an opening at the top that communicates with the mounting groove, and a positioning block is provided in the positioning groove that abuts against one of the positioning posts.

[0009] In the above-mentioned Hall element coating equipment, the positioning block includes a fixing surface and an abutting surface. The fixing surface is arc-shaped and adapts to the outer circumferential surface of the welding pin fixing frame. When the stator frame is installed in the fixing block, the fixing surface abuts against the welding fixing frame, one of the positioning pins abuts against the abutting surface, and an abutting block is also fixedly installed in the positioning groove to abut against another positioning pin.

[0010] In the above-mentioned Hall element coating equipment, a fixed plate is rotatably arranged on the rotating disk, a driving lifting component is arranged on the fixed plate, an installation plate is fixedly arranged on the driving lifting component, a pre-pressure column is slidably arranged on the installation plate, a pre-pressure head is fixed on the pre-pressure column, and a pre-pressure spring is sleeved on the pre-pressure column, which abuts against the installation plate and the pre-pressure head respectively.

[0011] In the aforementioned Hall element coating equipment, a sensing ring is fixedly installed on the upper end face of the pre-pressure column, and a proximity switch is also fixedly installed on the mounting plate. When the pre-pressure head is not working, the sensing ring rests on the mounting plate. When the pre-pressure head begins to press down, the pre-pressure head abuts against the Hall element and remains stationary, while the mounting plate drives the proximity switch to continue moving downward.

[0012] In the above-mentioned Hall element coating equipment, the fixed plate is provided with an extension cylinder, and the cylinder rod of the extension cylinder is fixedly provided with a glue receiving tray. When the coating equipment stops working, the extension cylinder drives the glue receiving tray to extend below the dispensing machine.

[0013] In the above-mentioned Hall element coating equipment, the extrusion device includes a mounting frame disposed on the curing station, an extrusion cylinder is disposed on the top of the mounting frame, an extrusion head is fixedly disposed on the drive rod of the extrusion cylinder, the curing agent spray can is fixed on the mounting frame, the operation of the extrusion cylinder drives the extrusion head to move down to extrude the spray nozzle of the spray can, and the relative angle between the curing agent spray can and the mounting frame is adjustable.

[0014] In the aforementioned Hall element coating equipment, the mounting frame includes two parallel mounting columns, and two fixing plates are vertically arranged between the two mounting columns. The extrusion cylinder is fixed on one of the fixing plates, and the curing agent spray can is fixed on the other fixing plate. Both ends of the fixing plates are vertically arranged with connecting plates. The connecting plates are provided with connecting holes and arc-shaped waist holes. Set screws pass through the connecting holes and arc-shaped waist holes respectively and are screwed to the mounting columns.

[0015] In the aforementioned Hall element adhesive coating equipment, the dispensing machine is also connected to a glue storage tank, which is connected to the dispensing machine via a glue delivery pipe. The glue storage tank is equipped with a glue reflection sensor to monitor the glue in the glue delivery pipe.

[0016] The Hall element coating equipment described above also includes a testing station located between the curing station and the pre-pressing station, and an industrial testing camera is installed on the testing station.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) Using glue coating equipment to replace the existing manual assembly operation can increase the assembly efficiency of stator components while reducing production costs and meeting the needs of industrialized production.

[0019] (2) The preload head is made of flexible material to avoid hard collision with the Hall element and damage to the Hall element. The setting of the preload spring allows for collision buffering between the preload head and the Hall element, ensuring that the preload head will not damage the Hall element.

[0020] (3) When the equipment needs to be stopped for replacement or adjustment, the glue in the dispensing machine may still drip under the action of gravity. Therefore, an extendable glue receiving tray is provided on the fixed plate to receive the glue that may drip from the dispensing machine. Attached Figure Description

Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0030] like Figures 1-6 As shown, a Hall element coating device includes a rotating disk 100 that can rotate circumferentially. A pre-pressing station, a coating station, and a curing station are sequentially distributed outside the circumference of the rotating disk 100. A stator frame 101 is placed on the rotating disk 100 and moves between the pre-pressing station, the coating station, and the curing station as the rotating disk 100 rotates.

[0031] The pre-compression station is equipped with a pre-compression head 102 that can move up and down relative to the rotary table 100;

[0032] The glue application station is equipped with a glue dispensing machine 103 that can move vertically up and down;

[0033] The curing station is equipped with an extrusion device and a curing agent spray can 104. The extrusion device squeezes the nozzle of the spray can to spray the curing agent onto the Hall element after dispensing.

[0034] The operation process of the above-mentioned gluing equipment is as follows: the Hall element is manually assembled onto the stator frame 101, and then the stator frame 101 is placed on the rotary table 100 located at the pre-pressing station. The pre-pressing head 102 moves down to press the Hall element into the stator frame 101. Then the rotary table 100 rotates and drives the stator frame 101 to the gluing station to apply glue to the connection between the Hall element and the stator frame 101. After gluing, the stator frame 101 moves to the curing station for curing agent spraying. It is worth mentioning that after the rotary table 100 rotates and drives the stator frame 101 from the pre-pressing station to the gluing station, the next stator frame 101 can be placed on the mounting block 122. During the process of the pre-pressing head 102 pressing down, the dispensing machine 103 moves down synchronously to perform the gluing operation.

[0035] In this embodiment, the use of adhesive coating equipment replaces the existing manual assembly operation, which increases the assembly efficiency of the stator assembly while reducing production costs and meeting the needs of industrialized production.

[0036] Preferably, the rotating disk 100 has three mounting blocks 122 distributed circumferentially. Each mounting block 122 has a mounting groove 106 with an opening at the upper end for mounting the stator frame 101. A positioning block 107 is fixedly provided on the side of the mounting block 122. Multiple positioning posts 108 are provided on the side of the stator frame 101 facing the welding needle fixing frame. The positioning block 107 has a positioning groove 109 with an opening at the upper end that communicates with the mounting groove 106. A limit block 110 is provided in the positioning groove 109 to abut against one of the positioning posts 108.

[0037] More preferably, the limiting block 110 includes a fixing surface 111 and an abutting surface 112. The fixing surface 111 is arc-shaped and conforms to the outer circumferential surface of the welding needle fixing frame. When the stator frame 101 is installed in the fixing block, the fixing surface 111 abuts against the welding fixing frame, one of the positioning pins 108 abuts against the abutting surface 112, and an abutting block 122 is also fixedly installed in the positioning groove 109 to abut against another positioning pin 108.

[0038] In this embodiment, after the Hall element is manually installed on the stator frame 101, the Hall element is positioned directly above the stator frame 101. The stator frame 101 is placed in the mounting groove 106 while keeping its position unchanged. The welding fixing bracket abuts against the fixing surface 111 on the positioning block limit block 110. Two of the positioning pins 108 on the stator frame 101 abut against the abutting block and the abutting surface 112, respectively, thus fixing the position of the stator frame 101.

[0039] It is worth mentioning that the abutting block 122 and the abutting surface 112 abut against the opposite sides of the two positioning posts 108, which restricts the stator frame 101 from rotating forward or backward.

[0040] Preferably, a fixed disk 113 is rotatably mounted on the rotating disk 100, a driving lifting component is mounted on the fixed disk 113, an mounting plate 114 is fixedly mounted on the driving lifting component, a pre-compression column 115 is slidably mounted on the mounting plate 114, a pre-compression head 102 is fixed on the pre-compression column 115, and a pre-compression spring 116 is sleeved on the pre-compression column 115, which abuts against the mounting plate 114 and the pre-compression head 102 respectively.

[0041] In this embodiment, the fixed disk 113 is stationary, while the rotating disk 100 rotates relative to the fixed disk 113. The pre-pressure head 102 is made of a flexible material to avoid hard collisions with the Hall element and damage to the Hall element. The pre-pressure spring 116 allows for collision buffering between the pre-pressure head 102 and the Hall element, ensuring that the pre-pressure head 102 will not damage the Hall element. It also allows for adjustment of the clamping force between the pre-pressure head 102 and the Hall element. Insufficient pressure will result in the Hall element not being properly pressed in, while excessive pressure will damage the Hall element.

[0042] It is worth mentioning that the driving lifting component includes a driving cylinder 117, a fixed column 118 is provided on the fixed plate 113, the driving cylinder 117 and the fixed column 118 are slidably engaged, and a limit block 119 is fixedly provided on the driving cylinder 117. Two limit columns 120 are provided on the fixed column 118. The limit block 119 and the limit column 120 are located on the same vertical line, and the limit block 119 is located between the two limit columns 120, thereby limiting the maximum working stroke of the driving cylinder 117.

[0043] More preferably, a sensing ring 121 is fixedly provided on the upper end face of the pre-compression column 115, and a proximity switch is also fixedly provided on the mounting plate 114. When the pre-compression head 102 is not working, the sensing ring 121 rests on the mounting plate 114. When the pre-compression head 102 starts to press down, the pre-compression head 102 abuts against the Hall element and remains stationary, and the mounting plate 114 drives the proximity switch to continue to move down.

[0044] In this embodiment, the mounting plate 114 is fixed on the drive cylinder 117. As the drive cylinder 117 moves up and down, the sensing ring 121 rests on the mounting plate 114 and is fixed to the precast column, supporting the pre-compression column 115. At the same time, when the pre-compression head 102 starts to press down, the pre-compression head 102 abuts against the Hall element and presses the Hall element into the stator frame 101. Then the pre-compression head 102 remains stationary. The mounting plate 114 drives the proximity switch to continue to move down and approach the proximity switch. If the proximity switch detects the presence of the sensing block, it indicates that the pressure of the pre-compression spring 116 is too high. The drive cylinder 117 moves up quickly and drives the pre-compression head 102 to reset.

[0045] It is worth mentioning that a fixing block with an oblong groove is fixedly installed on the mounting plate 114, and the induction switch is installed in the oblong groove, so that the position of the induction switch in the vertical direction is adjustable.

[0046] More preferably, the fixed plate 113 is provided with an extension cylinder 123, and a glue receiving plate 124 is fixedly provided on the cylinder rod of the extension cylinder 123. When the glue application equipment stops working, the extension cylinder 123 drives the glue receiving plate 124 to extend below the glue dispensing machine 103.

[0047] In this embodiment, when the equipment needs to be paused for replacement or adjustment, the glue in the dispensing machine 103 may still drip under the action of gravity. Therefore, an extendable glue receiving tray 124 is provided on the fixed plate 113 to receive the glue that may drip from the dispensing machine 103.

[0048] It is worth mentioning that a shelf 125 with mounting holes is fixedly installed on the cylinder rod extending from the cylinder 123. The glue receiving tray 124 is conical in shape. After the lower end of the glue receiving tray 124 passes through the mounting hole, the outer wall of the winch is locked in the mounting hole to fix the glue receiving tray 124.

[0049] Preferably, the extrusion device includes a mounting frame 126 set on the curing station, an extrusion cylinder 127 is set on the top of the mounting frame 126, an extrusion head 128 is fixedly set on the drive rod of the extrusion cylinder 127, and the curing agent spray can 104 is fixed on the mounting frame 126. When the extrusion cylinder 127 works, it drives the extrusion head 128 to move down to extrude the spray can nozzle, and the relative angle between the curing agent spray can 104 and the mounting frame 126 is adjustable.

[0050] In this embodiment, the drive rod moves the extrusion head 128 downward to press the spray nozzle, causing the curing agent spray can 104 to spray curing agent onto the Hall element of the stator frame 101, curing the bonding adhesive between the Hall element and the stator frame 101. The relative angle between the curing agent spray can 104 and the mounting bracket 126 is adjustable, so that the angle of the curing agent sprayed from the curing agent spray can 104 is adjustable.

[0051] More preferably, the mounting bracket 126 includes two parallel mounting posts 129, and two fixing plates 130 are vertically arranged between the two mounting posts 129. The extrusion cylinder 127 is fixed on one of the fixing plates 130, and the curing agent spray can 104 is fixed on the other fixing plate 130. Both ends of the fixing plate 130 are vertically arranged with connecting plates 131. The connecting plate 131 is provided with connecting holes 132 and arc-shaped waist holes 133. The set screw passes through the connecting holes 132 and the arc-shaped waist holes 133 respectively and is screwed to the mounting posts 129.

[0052] In this embodiment, the set screw passes through the connecting hole 132 on the connecting plate 130 and is screwed to the mounting post 129 to fix the fixing plate 130 in the vertical direction. The set screw passes through the arc-shaped waist hole 133 on the connecting plate 130 and is screwed to the mounting post 129 to fix the relative angle between the curing agent spray can 104 and the mounting post 129. When it is necessary to adjust the angle of the curing agent spray can 104, the set screw is loosened and the fixing plate 130 is rotated around the set screw at the connecting hole 132. It is worth mentioning that the setting of the set screw makes the height of the two fixing plates 130 adjustable in the vertical direction.

[0053] Preferably, the dispensing machine 103 is also connected to a glue storage tank 134, which is connected to the dispensing machine 103 via a glue delivery pipe. The glue storage tank 134 is equipped with a glue reflection sensor to monitor the glue in the glue delivery pipe.

[0054] In this embodiment, the glue delivery tube is made of transparent material, and a mounting bracket 135 is fixedly installed at the upper end of the glue storage tank 134. The mounting bracket 135 is provided with a waist-shaped hole, and the glue reflection sensor is fixed in the waist-shaped hole. The glue reflection sensor monitors the glue in the delivery tube to ensure that glue is sprayed out of the dispensing machine 103 to the connection between the Hall element and the stator frame each time.

[0055] More preferably, it also includes a testing station set between the curing station and the pre-compression station, and an industrial testing camera is installed on the testing station.

[0056] In this embodiment, an industrial inspection camera is added to compare the solidified stator frame 101. Qualified finished products are taken out and flow to the next process.

[0057] It is worth mentioning that an additional mounting block 122 is provided on the stator frame 101 to position the stator frame 101 that needs to be monitored at the inspection station.
