Description

Technical Field

[0001] This invention relates to the field of automated equipment, and more particularly to a mobile phone battery assembly device. Background Technology

[0002] During mobile phone assembly, the battery needs to be installed into the battery compartment of the phone's front casing, and the flexible ribbon cable connector connected to the battery is fastened to the motherboard socket. For example, the existing patent application number CN202020975484.2U discloses a battery insertion device that uses a pressing mechanism, a positioning mechanism, and a lifting and supporting mechanism to align and press the battery with the casing, primarily addressing the stability issue of the battery's insertion into the casing. Another existing patent application number CN202123020337.3U discloses an automatic assembly structure for BTB connector PCB boards, which uses a three-axis device, a gripper mechanism, and a visual positioning mechanism to complete the connector docking between circuit boards.

[0003] The aforementioned technologies focus on the assembly of battery casing and rigid circuit board mating, respectively, but they still struggle to simultaneously address the synchronous placement and removal of the battery body and its connectors, cable posture constraints, separate correction, and stress detection at different assembly stages. In actual production, connector fastening still requires manual operation, which is inefficient and prone to incomplete fastening and component damage due to positioning deviations or unstable pressing pressure. Summary of the Invention

[0004] In view of the above technical problems, the present invention provides a mobile phone battery assembly device to solve the problems of separation between battery installation and connector fastening, unstable connector cable posture, difficulty in accurately matching assembly positions, and difficulty in reliably controlling pressing pressure in the existing mobile phone battery assembly process.

[0005] Other features and advantages of the invention will become apparent from the following detailed description, or may be learned in part by practice of the invention.

[0006] According to one aspect of the present invention, a mobile phone battery assembly device is disclosed, comprising a transfer module having Y-axis and X-axis moving directions, and an assembly module synchronously driven by the transfer module. The assembly module includes a battery assembly mechanism and a connector assembly mechanism. A transfer module, a visual inspection module, and an assembly station are disposed below the transfer module. The transfer module is used to position the battery to be assembled. The battery assembly mechanism is used to clamp and remove the battery from the transfer module. The connector assembly mechanism is used to synchronously clamp the connector of the battery. The visual inspection module is used to photograph and position the battery and its connector removed by the assembly module. The assembly module installs the removed battery into the product at the assembly station, wherein: The battery assembly mechanism includes a first Z-axis assembly mounted on the transplanting module, a first rotatable correction rotation assembly driven to rise and fall by the first Z-axis assembly, and a suction plate assembly mounted on one side of the first correction rotation assembly. The suction plate assembly includes a fixed seat, a connecting seat, and a suction head. The fixed seat is connected to the connecting seat via a first spring. The connecting seat has a limit groove and a freely sliding limit block. The fixed seat is connected to a first force sensor, which is also connected to the limit block. The connecting seat is slidably mounted on the first correction rotation assembly via a slider and a slide rail. The connector assembly mechanism is arranged side by side with the battery assembly mechanism. The connector assembly mechanism includes a second Z-axis assembly mounted on the transfer module, a second rotatable correction rotation assembly driven to rise and fall by the second Z-axis assembly, a clamping assembly and a pressing assembly respectively mounted on both sides of the second correction rotation assembly. The clamping assembly includes a gripper cylinder for gripping the connector and a gripper lifting cylinder for driving the gripper cylinder to rise and fall. The pressing assembly includes an adjusting seat fixedly connected to the second correction rotation assembly, a mounting seat slidably connected to the second correction rotation assembly, a first pressing head and a second pressing head mounted on the mounting seat. The adjusting seat and the mounting seat are connected by a second spring and a guide post. A second force sensor is provided in the mounting seat. One end of the guide post is fixed to the adjusting seat, and the other end contacts the second force sensor. The first pressing head is used to press the cable of the battery connector to straighten the cable. The second pressing head is located between the two grippers of the gripper cylinder to limit the clamping stroke of the two grippers and to press the connector held by the two grippers into the socket of the product.

[0007] Furthermore, both the first and second correction rotation components include a motor, a coupling connected to the motor drive end, and a correction shaft connected to the coupling.

[0008] Furthermore, the transfer module includes a fixture for carrying the battery, a rotary cylinder for driving the fixture to rotate, a positioning cylinder for pressing against one side of the battery, and a lifting cylinder disposed at one end of the fixture. The driving end of the lifting cylinder is connected to a lifting block. Before the jaws of the connector assembly mechanism clamp the connector of the battery, the lifting cylinder drives the lifting block to rise, so as to cooperate with the second pressure head to pre-fix the connector.

[0009] Furthermore, the first and second correction rotation components are used to drive rotation based on the image positioning results of the visual inspection module, so that the posture of the battery and connector being gripped meets preset conditions.

[0010] Furthermore, the gripper lifting cylinder is used to drive the gripper cylinder and the two grippers to move vertically relative to the second pressure head, so that the two grippers can exit the pressing path of the second pressure head.

[0011] The technical solution of the present invention has the following beneficial effects: By synchronously moving the battery assembly mechanism and the connector assembly mechanism, the battery body and its connector can be reliably supported and clamped during the same assembly process, avoiding the need for manual searching and fastening of the connector after the battery is transferred. The transfer module can mechanically position the battery and connector before picking them up, and the first pressure head can constrain the cable posture before the connector is clamped, so that the connector is in a suitable clamping position. After the battery and connector are removed, the visual inspection module takes pictures to locate them, and the first and second correction rotation components can respectively correct the posture of the battery and connector, reducing the cumulative positional error between them.

Detailed Implementation

[0014] The exemplary implementation will now be described more fully with reference to the accompanying drawings.

[0015] The accompanying drawings are merely illustrative of the invention. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. It is understood that the proportions of the various components in the drawings do not constitute a limitation of the invention.

[0016] like Figures 1 to 14 As shown in the embodiment of this specification, a mobile phone battery assembly device is provided, including a transfer module 1 with Y-axis and X-axis moving directions, and an assembly module 2 synchronously driven by the transfer module 1. The assembly module 2 includes a battery assembly mechanism 21 and a connector assembly mechanism 22. A transfer module 3, a visual inspection module 4, and an assembly station 5 are arranged below the transfer module 1. The transfer module 3 is used to position the battery 100 to be assembled. The battery assembly mechanism 21 is used to clamp and remove the battery 100 from the transfer module 3. The connector assembly mechanism 22 is used to synchronously clamp the connector 101 of the battery 100. The visual inspection module 4 is used to photograph and position the battery 100 and its connector 101 removed by the assembly module 2. The assembly module 2 installs the removed battery 100 into the product at the assembly station 5, wherein: The battery assembly mechanism 21 includes a first Z-axis assembly 211 mounted on the transfer module 1, a first correction rotation assembly 212 that is driven to rise and fall by the first Z-axis assembly 211 and can be rotated in a controlled manner, and a suction plate assembly 213 mounted on one side of the first correction rotation assembly 212. The suction plate assembly 213 includes a fixed seat 2131, a connecting seat 2132, and a suction head 2133. The fixed seat 2131 is connected to the connecting seat 2132 by a first spring 2134. The connecting seat 2132 is provided with a limit groove 2135 and a freely sliding limit block 2136. The fixed seat 2131 is connected to a first force sensor 2137 and the first force sensor 2137 is also connected to the limit block 2136. The connecting seat 2132 is slidably mounted on the first correction rotation assembly 212 by a slider and a slide rail. The connector assembly mechanism 22 is arranged side by side with the battery assembly mechanism 21. The connector assembly mechanism 22 includes a second Z-axis assembly 221 mounted on the transfer module 1, a second rotatable alignment correction rotary assembly 222 driven to rise and fall by the second Z-axis assembly 221, a clamping assembly 224 and a pressing assembly 223 respectively mounted on both sides of the second alignment correction rotary assembly 222. The clamping assembly 224 includes a gripper cylinder 2241 for gripping the connector 101 and a gripper lifting cylinder 2242 for driving the gripper cylinder 2241 to rise and fall. The pressing assembly 223 includes an adjusting seat 2231 fixedly connected to the second alignment correction rotary assembly 222 and a mounting seat 223 slidably connected to the second alignment correction rotary assembly 222. 32. A first pressure head 2233 and a second pressure head 2234 are provided on the mounting base 2232. The adjusting base 2231 is connected to the mounting base 2232 through a second spring 2235 and a guide post. A second force sensor 2236 is provided in the mounting base 2232. One end of the guide post is fixed to the adjusting base 2231, and the other end contacts the second force sensor 2236. The first pressure head 2233 is used to press the ribbon cable 102 of the battery 100 connector 101 to straighten the ribbon cable 102. The second pressure head 2234 is located between the two jaws of the gripper cylinder 2241 to limit the gripping stroke of the two jaws and to press the connector 101 held by the two jaws into the socket 201 of the product.

[0017] The first correction rotation assembly 212 and the second correction rotation assembly 222 both include a motor 2121, a coupling 2122 connected to the drive end of the motor 2121, and a correction shaft 2123 connected to the coupling 2122.

[0018] The transfer module 3 includes a fixture 31 for carrying the battery 100, a rotary cylinder 32 for driving the fixture 31 to rotate, a positioning cylinder 33 for pressing one side of the battery 100, and a lifting cylinder 34 disposed at one end of the fixture 31. The driving end of the lifting cylinder 34 is connected to a lifting block 341. Before the grippers of the connector assembly mechanism 22 hold the connector 101 of the battery 100, the lifting cylinder 34 drives the lifting block 341 to rise so as to cooperate with the second pressure head 2234 to pre-fix the connector 101. It is worth explaining that, since the ribbon cable 102 of the battery 100 is made of soft FPC material, even if the first pressure head 2233 presses the ribbon cable 102 tightly, the connector 101 may still sag or tilt, which makes it impossible for the gripper to directly hold the connector 101. By cooperating with the second pressure head 2234 and the lifting block 341, the lifting block 341 lifts the connector 101 and the second pressure head 2234 presses down on the connector 101, eliminating the possible sag or tilt of the connector 101, so that the gripper can directly hold the connector 101.

[0019] The first correction rotation component 212 and the second correction rotation component 222 are used to drive rotation according to the image positioning result of the visual inspection module 4, so that the posture of the battery 100 and connector 101 being picked up and held meets the preset conditions.

[0020] The gripper lifting cylinder 2242 is used to drive the gripper cylinder 2241 and the two grippers to move vertically relative to the second pressure head 2234, so that the two grippers can exit the pressing path of the second pressure head 2234.

[0021] Working principle: This equipment is used in conjunction with other equipment on the production line. The other equipment transports the battery 100 and the phone casing 200. The phone casing 200 has a socket 201, and the battery 100 has a connector 101 and a ribbon cable 102. Figure 14As shown. The transfer module 3 carries the battery 100 via the fixture 31. The rotary cylinder 32 rotates the battery 100 to the picking direction, and the positioning cylinder 33 pushes the battery 100 against the positioning reference. The transfer module drives the assembly module 2 to the picking position. The second Z-axis assembly 221 drives the first pressure head 2233 to press against the connector 101 cable 102, causing the cable 102 to unfold and stabilizing the connector 101 in the clamping area. The second pressure head 2234 presses down, and the lifting cylinder 34 drives the lifting block 341 to support the connector 101, thus fixing the connector 101. The gripper cylinder 2241 then clamps the connector 101. The first Z-axis assembly 211 drives the suction plate assembly 213 to descend, causing the suction head 2133 to adsorb the battery 100. When the suction head 2133 contacts the battery 100, the connecting seat 2132 slides along the slide rail relative to the first correction rotation assembly 212. The first spring 2134 generates a buffer, and the limiting block 2136 transmits the force to the first force sensor 2137 to avoid rigid impact on the battery 100 during the suction process.

[0022] After the suction and clamping are completed, the first Z-axis assembly 211 and the second Z-axis assembly 221 are raised synchronously, and the transfer module moves the battery 100 and connector 101 above the inspection module 4. The inspection module 4 acquires the actual posture of the battery 100 and connector 101, the first correction rotation assembly 212 adjusts the orientation of the battery 100, and the second correction rotation assembly 222 adjusts the orientation of the connector 101. The battery assembly mechanism 21 descends and installs the battery 100 into the product. During the installation process, the first spring 2134 provides floating cushioning, and the first force sensor 2137 detects the installation load on the battery 100 to determine whether the battery 100 is pressed into place.

[0023] While the battery 100 is being installed, the connector assembly mechanism 22 moves the connector 101 above the product socket 201. The second Z-axis assembly 221 continues to drive the pressing assembly 223 to descend, and the second pressing head 2234 presses the connector 101 into the product socket 201. Then, the gripper lifting cylinder 2242 drives the gripper cylinder 2241 and the two grippers to move relative to the second pressing head 2234, causing the two grippers to exit the pressing path of the second pressing head 2234. During the pressing process, the mounting base 2232 slides relative to the second correction rotation assembly 222 and compresses the second spring 2235. The guide column transmits the pressing reaction force to the second force sensor 2236 to detect the pressing load of the connector 101 and buffer abnormal impacts. After the connector 101 is engaged, the assembly module 2 resets and enters the next assembly cycle.

[0024] As can be seen from the above embodiments, the present invention has the following beneficial effects: By synchronously moving the battery assembly mechanism 21 and the connector assembly mechanism 22, the battery 100 body and its connector 101 can be reliably supported and clamped during the same assembly process, avoiding the need for manual searching and fastening of the connector 101 after the battery 100 has been transferred. The transfer module 3 can mechanically position the battery 100 and connector 101 before material handling, and the first pressure head 2233 can constrain the posture of the cable 102 before the connector 101 is clamped, so that the connector 101 enters a suitable clamping position. After the battery 100 and connector 101 are removed, the inspection module 4 takes pictures and positions them. The first correction rotation component 212 and the second correction rotation component 222 can respectively correct the posture of the battery 100 and connector 101, reducing the cumulative positional error between them.

[0025] Among them, the first force sensor 2137 can detect the installation load of the battery 100 and help determine whether the battery 100 is installed in place. The second force sensor 2236 can detect the axial load during the pressing process of the connector 101, so that the second pressure head 2234 stops pressing when abnormally obstructed, and judges the fastening state of the connector 101 in combination with the pressing displacement, thereby improving the consistency, stability and yield of battery 100 installation and connector 101 fastening.

[0026] Other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
