Description

Technical Field

[0001] This invention relates to the field of magnet processing technology, and in particular to a magnetic component gripper device. Background Technology

[0002] Magnetic components are widely used in 3C electronic products. Due to the limited internal space of electronic products, the dimensional accuracy requirements for magnetic components are very high. A typical magnetic component consists of a set of magnets with an iron component glued on top. The magnets and iron component are then glued and aligned, making this assembly process crucial and directly affecting the overall dimensions of the magnetic component.

[0003] There are two existing technical solutions: one is manual bonding, which typically involves using two right-angled molds to press the magnetic component together; the other is automatic bonding, which usually involves creating a positioning fixture slot into which the magnetic component is placed to ensure that the magnet and the iron part are aligned during bonding.

[0004] Manually bonding magnetic components has disadvantages such as low efficiency and low assembly accuracy. Right-angle tooling also requires periodic cleaning of residual adhesive with an alcohol cloth. Summary of the Invention

[0005] The purpose of this invention is to provide a magnetic component gripper device to solve the technical problems of low efficiency and low assembly accuracy in the manual bonding of magnetic components in the prior art. 。 The preferred technical solutions among the many technical solutions provided by this invention can produce a variety of technical effects, which are described in detail below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The present invention provides a magnetic component gripper device, including a chassis, a fixture plate disposed on the chassis, and a first cylinder disposed on the chassis. The first cylinder is located above the fixture plate, the piston rod end of the first cylinder faces the fixture plate, and the movement direction of the first cylinder piston rod is perpendicular to the fixture plate. The end of the first cylinder piston rod is fixedly installed on a gripper cylinder. Four cylinder grippers are installed on the output end of the gripper cylinder. The four cylinder grippers move along the radial direction of the gripper cylinder, and the movement path of the cylinder grippers is located on the diameter line of the gripper cylinder. A working surface is provided on the opposite side wall of the four cylinder grippers.

[0008] By adopting the above technical solution, during use, the operator places the magnetic sheet on the fixture plate and lays the iron sheet to be bonded to the magnetic sheet on the magnetic sheet. Adhesive for bonding is applied between the two. Then, the first cylinder is activated, driving the gripper cylinder to move vertically towards the fixture plate. When the gripper is about to contact the plane of the fixture plate, the first cylinder stops moving. At the same time, the magnetic sheet assembly is positioned between the four gripper cylinders. The gripper cylinder then activates, driving the four gripper cylinders to move towards the axis of the gripper cylinder, thus bringing the working surface against the sidewalls of the magnetic sheet and the iron sheet. This ensures the magnetic sheet and the iron sheet are bonded and aligned, thereby solving the problems of low efficiency and low assembly accuracy associated with manual bonding of magnetic components.

[0009] Optionally, the extension direction of the working surface is parallel to the axis of the gripper cylinder.

[0010] By adopting the above technical solution, when in use, the gripper cylinder only needs to drive the four cylinder grippers to move in the radial direction of the gripper cylinder to achieve the alignment of the magnetic sheet and the iron sheet, and the working surface parallel to the axis of the gripper cylinder improves the accuracy of the magnetic sheet and the iron sheet during assembly.

[0011] Optionally, the angle between the extension direction of the working surface and the axis of the gripper cylinder is in the range of 30-60 degrees.

[0012] By adopting the above technical solution, during use, the gripper cylinder drives four cylinder grippers to move in the radial direction of the grippers, so that the sidewalls of the magnetic sheet and the iron sheet abut against the working surface of the cylinder gripper. Furthermore, by changing the angle between the working surface and the axis of the gripper cylinder, the assembly and bonding alignment can be achieved when the width of the magnetic sheet / iron sheet is greater than the width of the iron sheet / magnetic sheet.

[0013] Optionally, the cylinder gripper has a notch with an opening located on the working surface.

[0014] By adopting the above technical solution, when in use, the gripper cylinder drives the four cylinder grippers to move in the radial direction of the grippers, so that the sidewalls of the magnetic sheet and the iron sheet abut against the working surface of the cylinder gripper. Furthermore, by opening the cylinder gripper and setting a notch at the working surface, it is convenient to accommodate the raised magnetic sheet / iron sheet in the notch, thereby completing the assembly, bonding and alignment between the magnetic sheet and the iron sheet.

[0015] Optionally, an alcohol box and a second cylinder are installed on the box body. The second cylinder is fixedly connected to the box body, and the first cylinder is fixedly connected to the piston rod of the second cylinder. The piston rod of the second cylinder is arranged to move horizontally. The alcohol box is located below the gripper cylinder and is located on the moving path of the piston rod of the second cylinder.

[0016] By adopting the above technical solution, when the assembly, bonding and alignment of the magnetic sheet and the iron sheet is completed, the first cylinder is activated to drive the gripper cylinder to move, detaching from the bonding of the magnetic sheet and the iron sheet, so that it is positioned above the fixture plate. Then the second cylinder is activated, driving the first cylinder to move horizontally, causing the gripper cylinder to be positioned above the alcohol box. Then the first cylinder is activated, causing the cylinder gripper on the gripper cylinder to extend into the alcohol box to complete the cleaning of the cylinder gripper.

[0017] Optionally, the housing is further provided with a linear guide rail, which includes a motor fixedly mounted on the housing and a moving module located at the output end of the motor. The fixture plate is fixedly mounted above the moving module. The moving direction of the moving module is perpendicular to the moving direction of the first cylinder piston rod and the moving direction of the moving module is perpendicular to the moving direction of the second cylinder piston rod.

[0018] By adopting the above technical solution, when in use, the motor in the linear guide rail is started to drive the jig plate on the moving mold to move in the horizontal direction, so that more sets of magnetic sheets can be placed on the jig plate to realize the assembly, bonding and alignment of multiple sets of magnetic sheets, effectively improving work efficiency.

[0019] Optionally, a positioning plate is placed on the fixture plate, and the positioning plate has multiple positioning slots.

[0020] By adopting the above technical solution, when in use, the positioning plate is placed on the jig plate, and then the magnetic sheet group to be assembled is placed in the positioning groove on the positioning plate, so as to facilitate the alignment work of the cylinder gripper during the working process. After the magnetic sheet group is placed, the positioning plate is removed from the jig plate to avoid obstructing the working of the cylinder gripper.

[0021] The preferred technical solution of the present invention can also produce at least the following technical effects:

[0022] 1. By setting up cooperating cylinder grippers and fixture plates on the chassis, the gripper cylinder drives the four cylinder grippers to move towards the axis of the gripper cylinder, so that the working surface abuts against the side wall of the magnetic sheet and the iron sheet, thereby making the magnetic sheet and the iron sheet bond and align, thus solving the shortcomings of low efficiency and low assembly accuracy of manual bonding of magnetic components.

[0023] 2. By setting a linear guide rail that can carry the jig plate and move it, the motor in the linear guide rail drives the jig plate on the moving mold to move horizontally. This allows multiple sets of magnetic sheets to be placed on the jig plate, enabling the assembly, bonding and alignment of multiple sets of magnetic sheets, effectively improving work efficiency.

[0034] The following is in conjunction with the appendix Figure 1-5 To further describe this application in detail, embodiments of this application disclose a magnetic component gripper device.

[0035] Example 1:

[0036] Reference Figure 1 and Figure 2 As shown, a magnetic component gripper device includes a housing 100, a magnetic component 200, and a linear guide rail 300. The housing 100 has an open receiving cavity 140 on its side wall and a through groove 130 on its top surface, the through groove 130 extending above the opening of the receiving cavity 140. A second cylinder 110 is fixedly connected to the top surface of the housing 100, and the piston rod of the second cylinder 110 is fixedly connected to a first cylinder 120. The magnetic component 200 is mounted on the end of the piston rod of the first cylinder 120. The linear guide rail 300 is disposed at the opening of the receiving cavity 140 and fixedly connected to the bottom surface of the receiving cavity 140 of the housing 100. A fixture plate 240 for placing magnets and iron sheets is mounted on the linear guide rail 300.

[0037] In this embodiment, the piston rod of the second cylinder 110 extends parallel to the through groove 130 and is horizontally arranged. The cylinder body of the first cylinder 120 is fixedly connected to the end of the piston rod of the second cylinder 110, and the first cylinder 120 is slidably arranged in the through groove 130. The piston rod of the first cylinder 120 is vertically downward. When the piston rod of the second cylinder 110 drives the first cylinder 120 to fully extend, the magnetic pressure assembly 200 is located directly above the fixture plate 240.

[0038] Reference Figure 1 and Figure 2 As shown, the linear guide 300 includes a motor 320 and a moving module 310. The motor 320 is fixedly connected to the bottom surface of the housing 100's receiving cavity 140, and the moving mold assembly is also fixedly connected to the bottom surface of the housing 100's receiving cavity 140. The motor 320 drives the moving mold assembly to reciprocate in the horizontal direction. The horizontal movement direction of the moving mold assembly is perpendicular to the movement direction of the piston rod of the first cylinder 120 and also perpendicular to the movement direction of the piston rod of the second cylinder 110.

[0039] The jig plate 240 is fixedly connected to the top surface of the movable mold assembly, and a positioning plate 250 for positioning the magnet and iron sheet is installed on the jig plate 240. The positioning plate 250 has a through hole, and the jig plate 240 has a corresponding limiting groove. When the positioning plate 250 is installed on the jig plate 240, the through hole and the limiting groove are aligned, and a pin is inserted into the through hole and the limiting groove for positioning and fixation. When the magnet and positioning plate 250 on the jig plate 240 are assembled, bonded, and aligned using the magnetic assembly 200, the positioning plate 250 is removed from the jig plate 240.

[0040] The positioning plate 250 has multiple positioning slots that extend through it. These slots are evenly distributed along the length of the positioning plate 250, and each slot has an opening on its vertical sidewall for inserting a magnet and an iron sheet. The width and length of the positioning slots are greater than the width and length of the magnet and the iron sheet.

[0041] Reference Figure 1 and Figure 2 As shown, an alcohol box 150 is also provided on the box body. The alcohol box 150 is fixedly connected to the bottom surface of the receiving cavity 140, and the top surface of the alcohol box 150 is provided with an opening. The alcohol box 150 is located away from the opening of the receiving cavity 140 relative to the linear guide rail 300. When the second cylinder 110 drives the first cylinder 120 to fully retract, the magnetic component 200 on the second cylinder 110 is located just above the opening of the alcohol box 150.

[0042] Reference Figure 2 and Figure 3 As shown, the magnetic pressing assembly 200 includes a mounting plate 210, a plurality of gripper cylinders 220, and four cylinder grippers 230 corresponding to each gripper cylinder 220. The mounting plate 210 is fixedly connected to the end of the piston rod of the first cylinder 120, and the length extension direction of the mounting plate 210 is parallel to the length extension direction of the fixture plate 240.

[0043] In this embodiment, four gripper cylinders 220 are provided, and the four gripper cylinders 220 are evenly and fixedly disposed on the bottom surface of the mounting plate 210. The output ends of the gripper cylinders 220 are arranged downwards. The four cylinder grippers 230 are fixedly connected to the output ends of the gripper cylinders 220, that is, the four cylinder grippers 230 are arranged horizontally along the radial direction of the gripper cylinders 220, and the moving directions of the four cylinder grippers 230 all pass through the axis of the gripper cylinders 220.

[0044] The four cylinder grippers 230 have working surfaces 260 on their opposite sides for abutting against the magnet and the side wall of the iron sheet, wherein the extending direction of the working surfaces 260 is parallel to the axis of the gripper cylinders 220. Furthermore, when the gripper cylinders 220 are close to the plane of the fixture plate 240 during operation, the working surfaces 260 are parallel to the plane of the fixture plate 240.

[0045] Example 2:

[0046] The difference between this embodiment and Embodiment 1 lies in the structure of the cylinder gripper 230.

[0047] Reference Figure 4 As shown, the four cylinder grippers 230 have working surfaces 260 on their opposite sides for abutting against the magnet and the sidewall of the iron sheet. The angle between the extending direction of the working surface 260 and the axis of the gripper cylinder 220 is between 30 and 60 degrees. That is, when the gripper cylinder 220 is close to the plane of the fixture plate 240 during operation, the angle between the working surface 260 and the plane of the fixture plate 240 is 30-60 degrees. This allows for bonding and alignment operations where the magnet's length / width is greater than the iron sheet's length / width, and also where the magnet's length / width is less than the iron sheet's length / width.

[0048] In this embodiment, the working surface 260 and the jig plate 240 are shown at a 45-degree angle.

[0049] Example 3:

[0050] The difference between this embodiment and Embodiment 1 lies in the structure of the cylinder gripper 230.

[0051] Reference Figure 5 As shown, the four cylinder grippers 230 have working surfaces 260 on their opposite sides for abutting against the magnet and the sidewall of the iron sheet. Each cylinder gripper 230 has a notch 270 with an opening in the working surface 260. The position of the notch 270 can be adaptively changed according to the protruding position of the magnet / edge. Furthermore, this embodiment can also be combined with the working surface 260 in Embodiment 2, with the notch 270 formed in the inclined working surface 260 of the cylinder gripper 230.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
