Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and in particular to a lower housing assembly device and method. Background Technology

[0002] like Figure 1 The lower housing body 01 shown includes a connecting end 011 at the front end, a pin fixing part 012 in the middle, and a terminal support plate 013 at the rear end. The pin fixing part 012 has a socket 012a extending toward the connecting end 011 at one end away from the connecting end, and a slot 012b communicating with the socket is also present on the top of the front end of the pin fixing part 012. Figure 2 As shown, during the actual assembly, the two parallel central pin bodies 021 on the central pin terminal 02 crimped onto the cable need to be inserted into the two sockets 012 respectively. The central pin body 021 also has two locking teeth 021a that are adapted to the slots 012b. After inserting the central pin body 021 into the socket 012, the central pin body 021 needs to be pushed further in until the locking teeth 021a are lifted out of the slots 012b.

[0003] In the prior art, after the center pin terminal 01 is crimped, the lower housing is mostly assembled manually. However, manual operation is inefficient and the quality is difficult to guarantee. In order to improve processing efficiency, related technologies have begun to use mechanical assembly equipment that clamps the center pin terminal 02 and the lower housing body 01 separately and then brings them close together for insertion.

[0004] However, with the above-mentioned docking method, since the tray 013 extends away from the pin fixing part 012, it is easy to interfere with the center pin body 021 during docking, and the accuracy of the center pin body 021 being inserted into the socket 012 is also difficult to guarantee. Summary of the Invention

[0005] In view of at least one of the above technical problems, the present invention provides a lower housing assembly device and method, which adopts structural improvements to improve the accuracy and reliability of lower housing assembly.

[0006] According to a first aspect of the present invention, a lower housing assembly apparatus is provided, comprising: A feeding mechanism is used for conveying the lower plastic shell body, and the feeding mechanism has an output guide rail; The lower housing pushing mechanism is located at the output end of the output guide rail and includes a pushing component for clamping and transferring the lower housing body. A wire harness clamping mechanism is disposed opposite to the lower housing pushing mechanism, and includes a center pin clamping component whose clamping center is colined with the pushing component; The pushing component includes a first clamping block and a second clamping block arranged opposite each other in a horizontal direction. The first clamping block and the second clamping block are used to clamp the lower housing body and make the tray protrude from the outer end face of the clamping. The pushing component also includes a pressing block disposed at the clamping center of the first clamping block and the second clamping block. The pressing block is used to press the tray and has a guide groove corresponding to the insertion hole.

[0007] Furthermore, the bottom of the first clamping block has a support plate extending toward the direction of the second clamping block, and the opposing surfaces of the first and second clamping blocks have clamping grooves recessed toward the direction away from each other, the shape of which is adapted to the lower housing body.

[0008] Furthermore, the guide groove is provided through the bottom of the pressure block, and the outer edge of the guide groove has a guide surface. When the bottom of the pressure block abuts against the support plate, the top of the guide groove is aligned with the top of the insertion hole of the lower housing body.

[0009] Furthermore, the pushing component also includes a pushing drive, which includes a motor, a lead screw connected to the motor, a nut seat meshing with the lead screw, a rail arranged parallel to the lead screw, and a sliding seat slidably connected to the rail. The nut seat is fixedly connected to the sliding seat. A gripper cylinder is fixed on the sliding seat, and the first gripper block and the second gripper block are connected to the gripper cylinder.

[0010] Furthermore, a longitudinal drive member and a feed drive member connected to the longitudinal drive member are also fixed on the sliding seat. The pressure block is fixed on the feed drive member. The longitudinal drive member is used to drive the feed drive member to rise and fall. The feed drive member is used to drive the pressure block to press against or leave the support plate of the clamped lower rubber shell body.

[0011] Furthermore, the center needle clamping assembly includes two opposing clamping arms, the bottom of which extends toward the other to form a support plate, the thickness of which is not less than the height of the center needle body; The center pin clamping assembly also includes a splitting block disposed between the two clamping arms. The splitting block has a downwardly extending splitting plate at the bottom center. The splitting plate is driven to the middle of the two abutting clamps to form a slot for fixing the two center pin bodies.

[0012] Furthermore, the center pin clamping assembly also includes a top plate disposed at the bottom of the two abutment clamps. The top plate, the dividing plate, and the abutment clamps are close to each other to form a positioning space for clamping and fixing the two center pin bodies respectively.

[0013] Furthermore, the center pin clamping assembly also includes a first driving member for driving the two clamping arms to open or close, a second driving member for driving the dividing block to rise or fall, and a third driving member for driving the top plate to rise or fall.

[0014] Furthermore, after the longitudinal drive member inserts the perforation of the lower housing body into the end of the central needle body, it drives the pressure block to leave the abutting position. The center pin clamping assembly releases the constraint on the center pin, and under the clamping action of the carrier, continues to push the lower housing body until the locking teeth of the center pin terminal are engaged in the locking groove of the lower housing body.

[0015] According to a second aspect of the present invention, an assembly method for the aforementioned lower housing assembly device is also provided, comprising the following steps: The drive feeding mechanism transports the lower plastic shell body to the end of the output guide rail, and the push component clamps the lower plastic shell body; The drive block abuts against the support plate of the clamped lower rubber shell body; The carrier clamps the wire harness and delivers the center pin terminal to the clamping position of the center pin clamping assembly; Drive the two abutment plates toward the dividing plate until they clamp the two center pin bodies on both sides of the dividing plate and stop. The drive plate rises until it comes into contact with the bottom of the center needle body and stops. The drive push component moves toward the center pin clamping component until the free section of the center pin body enters the socket through the guide groove; The driving block moves away from the pallet, and the driving top plate moves away from the supporting position. The driving center pin clamping assembly releases the constraint on the center pin. The center pin harness is pushed to the lower housing body under the clamping of the carrier until the tooth is engaged in the slot and the pushing stops.

[0016] The beneficial effects of the present invention are as follows: After the first and second clamping blocks of the pushing component clamp the lower housing body, the pressing block presses down on the tray, causing the tray to deform at the end facing the center pin. Furthermore, the center pin body can smoothly enter the tray through the guide groove corresponding to the insertion hole by setting the guide groove on the pressing block. Compared with the prior art, this avoids interference between the center pin body and the tray, and also improves the accuracy of the center pin body when inserted into the insertion hole.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 2 to 7 The lower housing assembly equipment shown includes a feeding mechanism 1, a lower housing pushing mechanism 2, and a wire harness clamping mechanism 3. In an embodiment of the present invention, the overall processing flow is as follows: the feeding mechanism 1 first feeds the lower housing body 01, so that a single lower housing body 01 is conveyed to the lower housing pushing assembly 21; as shown Figure 3 As shown, the feeding mechanism 1 is used for conveying the lower plastic shell body 01. The feeding mechanism 1 has an output guide rail 11. It should be noted that the feeding mechanism 1 can be a vibratory feeder in the prior art, or other methods can be used to place the lower plastic shell body 01 on the output guide rail 11 in sequence.

[0024] Please continue to refer to Figure 3 In an embodiment of the present invention, the lower housing pushing mechanism 2 is disposed at the output end of the output guide rail 11, and includes a pushing component 21 for clamping and transferring the lower housing body 01. It should be noted that there are various ways to transfer the lower housing body 01 from the output guide rail 11 to the pushing mechanism. For example, the pushing component 21 can be disposed at the output end of the output guide rail 11, so that the output lower housing body 01 enters the clamping position of the pushing component 21. Of course, those skilled in the art can also set clamping and transferring claws as needed to clamp the lower housing body 01 released from the output end of the output rail 224 and place it at the clamping position of the pushing component 21.

[0025] In an embodiment of the present invention, the wire harness clamping mechanism 3 and the lower housing pushing mechanism 2 are arranged opposite to each other, including a center pin clamping component 31 whose clamping center is colinearly arranged with the pushing component 21; in specific operation, the center pin wire harness is clamped by the carrier on the circulating line and the center pin terminal 02 is moved to the center pin clamping component 31 for clamping, and the assembly of the center pin body 021 and the lower housing body 01 is realized by the pushing of the pushing component 21; the assembly here refers to inserting the center pin body 021 into the insertion hole 012a of the lower housing body 01, and making the locking teeth 021a on the center pin body 021 engage in the locking groove 012b.

[0026] Please refer to Figures 4 to 6 In an embodiment of the present invention, the pushing component 21 includes two horizontally arranged first clamping blocks 211 and second clamping blocks 212, which are used to clamp the lower housing body 01 and make the tray 013 protrude from the outer end face of the clamping. The pushing component 21 also includes a pressing block 213 disposed at the clamping center of the first clamping blocks 211 and the second clamping blocks 212, which is used to press the tray 013, and the pressing block 213 has a guide groove 213a corresponding to the insertion hole 012a.

[0027] like Figure 6 As shown, the pressure block 213 is L-shaped. The bottom of the pressure block 213 abuts against the support plate 013 before the pin is inserted, causing the free end of the support plate 013 to bend downward to a certain extent. This avoids interference between the center pin body 021 and the support plate 013 when the lower housing body 01 moves toward the center pin terminal 02. Furthermore, by providing a guide groove 213a on the pressure block 213 that corresponds to the insertion hole 012a, the pin first contacts the guide groove 213a and then enters the insertion hole 012a during the process of the lower housing body 01 moving toward the pin under the guidance of the guide groove 213a. This improves the accuracy of the pin body being inserted into the insertion hole 012a.

[0028] In the above embodiment, after the lower housing body 01 is clamped by the first clamping block 211 and the second clamping block 212 of the pushing component 21, the pressing block 213 presses down on the support plate 013, causing the end of the support plate 013 facing the center needle to deform. Furthermore, through the setting of the guide groove 213a on the pressing block 213 corresponding to the insertion hole 012a, the center needle body 021 can smoothly enter the insertion hole 012a through the guide groove 213a. Compared with the prior art, this avoids interference between the center needle body 021 and the support plate 013, and also improves the accuracy of the center needle body 021 when inserted into the insertion hole 012a.

[0029] Based on the above embodiments, please continue to refer to Figure 5In an embodiment of the present invention, the bottom of the first clamping block 211 has a support plate extending toward the second clamping block 212. The opposing surfaces of the first clamping block 211 and the second clamping block 212 have clamping grooves recessed toward the direction away from each other. The shape of the clamping grooves is adapted to the lower housing body 01. The support plate provides support for the lower housing body 01. It should also be noted that the adaptation of the clamping grooves to the lower housing body 01 means that the height of the clamping grooves is adapted to the lower housing body 01, so that the lower housing body 01 does not wobble after being clamped. Figure 5 and Figure 6 As shown in the embodiment of the present invention, when the lower housing body 01 is clamped, the end face where the insertion hole 012a is located is flush with the end faces of the first clamping block 211 and the second clamping block 212, so that the support plate 013 protrudes from the first clamping block 211 and the second clamping block 212. With this structural form, the pressure block 213 can keep the position of the insertion hole 012a unchanged when pressing down on the support plate 013.

[0030] Please continue to refer to Figure 5 and Figure 6 In an embodiment of the present invention, the guide groove 213a is provided through the bottom of the pressure block 213, and the outer edge of the guide groove 213a has a guide surface. When the bottom of the pressure block 213 abuts against the support plate 013, the top of the guide groove 213a is aligned with the top of the insertion hole 012a of the lower housing body 01. Here, "through the bottom" means that the guide groove 213a is a guide groove 213a with its opening facing downwards, and "guide surface" means... Figure 5 As shown, the pressure block 213 forms an arc-shaped surface on the end face facing the center needle body 021 at the edge of the guide groove 213a. With this structural form, on the one hand, the insertion accuracy can be guaranteed by the setting of the guide surface when the center needle body 021 deviates. On the other hand, after the center needle body 021 is inserted into the insertion hole 012a, the opening of the guide groove 213a facilitates the release of the pressure block 213.

[0031] There are several forms of the specific driver structure for push component 21. Please refer to [the relevant documentation]. Figure 4In some embodiments of the present invention, the pushing component 21 further includes a pushing drive component 22, which includes a motor 221, a lead screw 222 connected to the motor 221, a nut seat 223 meshing with the lead screw 222, a track 224 parallel to the lead screw 222, and a sliding seat 225 slidably connected to the track 224. The nut seat 223 is fixedly connected to the sliding seat 225. In specific driving, the motor 221 drives the lead screw 222 to rotate. Since the nut seat 223 is connected to the sliding seat 225, the movement of the nut seat 223 will drive the sliding seat 225 to move forward or backward along the track 224. The direction of movement is the direction in which the lower rubber shell body 01 moves toward the center needle body 021. In an embodiment of the present invention, a gripper cylinder is fixed on the sliding seat 225, and the first gripper block 211 and the second gripper block 212 are connected to the gripper cylinder.

[0032] Please continue to refer to Figure 4 In some embodiments of the present invention, a longitudinal drive member 226 and a feed drive member 227 connected to the longitudinal drive member 226 are also fixed on the sliding seat 225. The pressure block 213 is fixed on the feed drive member 227. The longitudinal drive member 226 is used to drive the feed drive member 227 to rise and fall. The feed drive member 227 is used to drive the pressure block 213 to press against or leave the support plate 013 of the clamped lower rubber shell body 01. In the embodiments of the present invention, the driving method for the pressure block 213 is as follows: first, the longitudinal driving member 226 is driven to rise, and then the feed driving member 227 is driven to move the pressure block 213 toward the tray 013. When it moves to the front end of the first clamping block 211 and the second clamping block 212, the longitudinal driving member 226 descends again, so that the pressure block 213 can press against the tray 013. Conversely, when the pressure block 213 leaves the tray 013, the longitudinal driving member 226 first drives the feed driving member 227 to rise, so that the pressure block 213 disengages from the tray 013, and then the feed driving member 227 retracts, so that the pressure plate is above the first clamping block 211 and the second clamping block 212.

[0033] In an embodiment of the present invention, since the center pin body 021 has two parallel pins, in order to improve the clamping accuracy of the two center pin bodies 021, such as... Figure 7 As shown, the center needle clamping assembly 31 includes two opposing clamping arms 311. The bottom of the clamping arms 311 extends toward each other to form a support plate 311a. The thickness of the support plate 311a is not less than the height of the center needle body 021. Please continue to refer to... Figure 7 The center pin clamping assembly 31 also includes a wire divider block 312 disposed between the two clamping arms 311. The wire divider block 312 has a downwardly extending wire divider plate 312a at the bottom center. The wire divider plate 312a is driven to the middle of the two abutting clamping plates 311a to form a slot for fixing the two center pin bodies 021. Figure 7 As shown, when clamping, the splitter plate 312a can be placed between the two abutting plates 311a. This creates two positions on both sides of the splitter plate 312a for clamping the two center needle conductors respectively. When the two abutting plates 311a fix the center needle body 021 to both sides of the splitter plate 312a, the two center needle bodies 021 correspond to the two insertion holes 012a of the lower housing body 01 respectively. It should be noted that when clamping the center needle body 021, the end of the center needle body 021 protrudes outside the abutting plate 311a.

[0034] Please continue to refer to Figure 7 In embodiments of the present invention, the center pin clamping assembly 31 further includes a top plate 313 disposed at the bottom of the two abutting clamping plates 311a. The top plate 313, the dividing plate 312a, and the abutting clamping plates 311a are close to each other to form a positioning space for clamping and fixing the two center pin bodies 021 respectively. Through the abutment of the top plate 313, two rectangular clamping spaces corresponding to the guide groove 213a are formed, further improving the positioning accuracy of the center pin body 021. It should also be noted that the specific driving forms of the clamping arms 311, the dividing plate 312a, and the top plate 313 are existing technologies. In some embodiments of the present invention, the center pin clamping assembly 31 further includes a first driving member for driving the two clamping arms 311 to open or close, a second driving member for driving the dividing block 312 to rise or fall, and a third driving member for driving the top plate 313 to rise or fall. The specific driving mechanism can be a cylinder or other existing linear drive structures, which will not be elaborated here.

[0035] In an embodiment of the present invention, in order to prevent the pressure block 213 from hindering the continued insertion of the center needle body 021 into the insertion hole 012a, the longitudinal drive member 226 drives the pressure block 213 away from the abutting position after the through hole of the lower housing body 01 is inserted into the end of the center needle body 021; the center needle clamping assembly 31 opens the constraint on the center needle, and under the clamping action of the carrier, continues to push the lower housing body 01 until the locking tooth 021a of the center needle terminal 02 is locked in the locking groove 012b of the lower housing body 01.

[0036] like Figure 8 As shown in the embodiments of the present invention, an assembly method for the aforementioned lower housing assembly device is also disclosed, including the following steps. The specific lower housing assembly method has been described in detail above, and those skilled in the art can understand it by referring to the above: S10: Drive the feeding mechanism 1 to transport the lower plastic shell body 01 to the end of the output guide rail 11, and clamp the lower plastic shell body 01 through the pushing component 21. S20: The drive block 213 abuts against the tray 013 of the clamped lower rubber shell body 01; S30: The carrier clamps the wire harness and delivers the center pin terminal 02 to the clamping position of the center pin clamping assembly 31; S40: Drive the two abutting clamps 311a toward the dividing plate 312a until the two center needle bodies 021 are clamped on both sides of the dividing plate 312a and then stop. S50: Drive the top plate 313 to rise until it stops against the bottom of the center pin body 021; it should be noted that the clamping steps of the center pin terminal 02 and the clamping steps of the plastic shell can be performed sequentially or simultaneously, and there is no limitation on their order.

[0037] S60: Drive the push component 21 to move toward the center pin clamping component 31, until the free section of the center pin body 021 enters the socket 012a through the guide groove 213a; S70: The driving pressure block 213 moves away from the support plate 013, and the driving top plate 313 moves away from the holding position. The driving center pin clamping assembly 31 releases its constraint on the center pin. The center pin harness, held by the carrier, is pushed to the lower housing body 01 until the locking teeth 021a engage with the slot 012b, at which point the pushing stops. It should be noted that releasing the constraint on the center pin means that the dividing plate 312a and the top plate 313 move away from the two clamping arms 311. To avoid the center pin clamping assembly 31 obstructing the lower housing, the carrier's clamping of the center pin harness can continue to provide pushing support, allowing the locking teeth 021a on the center pin body 021 to engage with the slot 012b, thus completing the assembly of the lower housing.

[0038] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
