Description

Technical Field

[0001] This invention relates to the field of relay manufacturing technology, and in particular to a contact assembly equipment. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is commonly used in automated control circuits, acting as an "automatic switch" that uses a small current to control a large current, playing roles such as automatic adjustment, safety protection, and circuit switching.

[0003] As per the instruction manual Figure 1-4 As shown, existing relays contain contacts and retaining rings. During relay manufacturing, the contacts and retaining rings need to be connected to each other. The contact includes a body and two connecting parts, which are spaced apart and connected to the body. Each of the two connecting parts has horizontally opened retaining holes on its opposite sidewalls. The retaining ring is an open ring. Currently, the contact and retaining ring are usually assembled manually. During assembly, the two connecting parts on the contact must first be inserted into the openings on the retaining ring. At this point, the distance between the two connecting parts cannot be too large, otherwise they cannot be inserted into the openings on the retaining ring simultaneously. Then, the two ends of the retaining ring need to be inserted into the two retaining holes respectively. At this point, the distance between the two connecting parts cannot be too small, otherwise the retaining ring may easily detach from the contact, or even the two ends may not be able to be inserted into the retaining holes simultaneously. The assembly process is cumbersome and difficult to operate. Moreover, existing contacts are usually made of metal and have a certain thickness, making manual assembly laborious. Summary of the Invention

[0004] The purpose of this invention is to provide a contact assembly assembly device to achieve automatic assembly of contact assemblies.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A contact assembly assembly device is provided. The contact assembly includes a contact and a retaining ring. The contact includes a body and two connecting parts. The connecting parts are spaced apart and are respectively connected to the body. The two connecting parts have horizontally opened retaining holes on their opposite sidewalls. The retaining ring is an open ring. The contact assembly assembly device includes a first fixing mechanism, a second fixing mechanism, a socket driving mechanism, and a spacing expansion mechanism.

[0007] The first fixing mechanism is used to fix the contact; the second fixing mechanism is used to fix the retaining ring; the insertion driving mechanism is used to drive the first fixing mechanism and / or the second fixing mechanism so that the two connecting parts of the contact on the first fixing mechanism enter the opening of the retaining ring on the second fixing mechanism, and so that the two ends of the retaining ring are respectively aligned with the retaining holes on the two connecting parts; the spacing expanding mechanism is used to expand the distance between the two connecting parts along the axial direction of the retaining hole so that the two ends of the retaining ring enter the retaining hole.

[0008] Furthermore, the first fixing mechanism includes a limiting seat and an upper limiting mechanism. The top shape of the limiting seat matches the bottom shape of the body portion. The limiting seat is used to place the body portion of the contact and restricts the horizontal displacement of the contact.

[0009] The upper limit mechanism includes an upper limit block and a first driving device. The bottom shape of the upper limit block matches the top shape of the main body. The first driving device is connected to the upper limit block and is used to drive the upper limit block to move closer to or away from the limiting seat. When the contact is placed on the limiting seat and the upper limit block is close to the limiting seat, the bottom of the upper limit block is close to the top of the main body.

[0010] Furthermore, it also includes a clamping mechanism, which includes clamping blocks and a second driving device. There are two clamping blocks, which are located on both sides of the contact and are positioned directly opposite the connecting part of the contact. The second driving device is used to horizontally drive the two clamping blocks to simultaneously abut against the connecting part or move away from the connecting part.

[0011] Furthermore, the top of the clamping block is provided with a relief groove to avoid the retaining spring. The relief groove passes through the side of the clamping block facing the connecting part and avoids the retaining hole. When the clamping block abuts against the connecting part and the two ends of the retaining spring are aligned with the retaining hole, the bottom surface of the relief groove is close to the retaining spring.

[0012] Furthermore, the second fixing mechanism includes a fixed base and a third driving device. A strip-shaped groove is formed on the side wall of the fixed base. A cam and two sliding blocks are arranged inside the groove. The cam is rotatably connected to the fixed base. The rotation axis of the cam is horizontally arranged and perpendicular to the length direction of the groove. The two sliding blocks are respectively located on both sides of the cam and close to the cam. The two sliding blocks are slidably connected to the fixed base, and a fixing post is protruding on the side away from the fixed base. The third driving device is used to drive the cam to rotate.

[0013] Furthermore, the side of the fixing seat is provided with a positioning groove, which is provided on the same side as the slide groove and located directly above the slide groove. The positioning groove avoids the retaining spring, and the side of the groove facing away from the cam is an arc surface. The arc surface is coaxially arranged with the cam and its size matches that of the retaining spring.

[0014] Furthermore, the slide groove is horizontally positioned along its length and perpendicular to the axis of the card hole; the cam is an elliptical cam; the fixed column is cylindrical and its length direction is consistent with the rotation axis direction of the cam; the third driving device includes a rack, a gear, and a cylinder, the gear is coaxially positioned with the cam and fixedly connected to the cam, the cylinder drives the rack and the driving direction is consistent with the length direction of the rack, and the rack meshes with the gear.

[0015] Furthermore, the insertion drive mechanism includes a support frame, a horizontal drive device, and a vertical drive device. The support frame is fixed relative to the first fixing mechanism. The horizontal drive device is fixedly mounted on the support frame and is driven by the vertical drive device. The driving direction of the horizontal drive device is perpendicular to the axial direction of the card hole. The vertical drive device is driven by the second fixing mechanism.

[0016] Furthermore, the widening mechanism includes a push rod and a fourth driving device. The fourth driving device is used to drive the push rod horizontally, and the driving direction is perpendicular to the axis of the card hole. The length direction of the push rod is consistent with the driving direction of the fourth driving device. One end of the push rod is directly opposite the gap between the two connecting parts, and can be inserted into and widen the gap between the two connecting parts as driven by the fourth driving device.

[0017] Furthermore, it also includes an opening positioning mechanism, which includes a positioning rod and a fifth driving device. The positioning rod is located below the first fixing mechanism, and its top end is directly opposite the snap ring on the first fixing mechanism. The fifth driving device is used to drive the positioning rod to rise and fall. The top end of the positioning rod can pass through the opening on the snap ring, and the dimension of the top end of the positioning rod in the direction of the snap hole axis is slightly smaller than the minimum distance between the two ends of the snap ring.

[0018] The present invention has the following beneficial effects:

[0019] This invention can automatically assemble contact assemblies. In use, the contacts and retaining rings are fixed by the first and second fixing mechanisms, respectively. Then, the contacts and retaining rings are driven to move closer together by the insertion driving mechanism, so that the two connecting parts on the plug simultaneously enter the openings on the retaining rings, and the two ends of the retaining rings are aligned with the locking holes on the two connecting parts. Next, the distance between the two connecting parts can be widened by the distance widening mechanism, so that the two ends of the retaining rings are inserted into the locking holes on the two connecting holes, thereby connecting the contacts and retaining rings to each other and completing the assembly of the contact assembly. The assembled contact assembly is tightly connected and not easily separated. This invention can effectively improve assembly efficiency by replacing manual assembly of contact assemblies.

[0043] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] This invention discloses a contact assembly assembly device for assembling relay contact assemblies 1. For example... Figure 1 As shown, the contact assembly 1 processed by the equipment includes a contact 11 and a retaining ring 12, wherein, as Figure 2-3As shown, the contact 11 includes a body portion 111 and two connecting portions 112. The two connecting portions 112 are spaced apart and integrally connected to the body portion 111. A locking hole 1121 is horizontally formed on the opposite sidewalls of each of the two connecting portions 112. The two locking holes 1121 are coaxially arranged. Figure 4 As shown, the retaining ring 12 is annular with an opening 121, which is formed between the two ends of the retaining ring 12.

[0045] like Figure 5-8 As shown, the device includes a first fixing mechanism 2, a second fixing mechanism 4, a socket driving mechanism 5, and a spacing expansion mechanism 6, all of which are mounted on a workbench. The first fixing mechanism 2 is used to fix the contact 11; the second fixing mechanism 4 is used to fix the retaining ring 12; the socket driving mechanism 5 is used to drive the first fixing mechanism 2 and / or the second fixing mechanism 4 so that the two connecting parts 112 of the contact 11 on the first fixing mechanism 2 enter the opening 121 of the retaining ring 12 on the second fixing mechanism 4, and so that the two ends of the retaining ring 12 are respectively aligned with the retaining holes 1121 on the two connecting parts 112; the spacing expansion mechanism 6 is used to expand the distance d1 between the two connecting parts 112 along the axial direction of the retaining hole 1121 so that the two ends of the retaining ring 12 enter the retaining hole 1121.

[0046] Specifically, the first fixing mechanism 2 includes a limiting seat 21 and an upper limiting mechanism 22, such as Figure 9 , 10 As shown, the top shape of the limiting seat 21 matches the bottom shape of the body portion 111. The top of the limiting seat 21 is provided with an inclined surface and a step that conforms to the shape of the body portion 111 of the contact 11, and the side is provided with a straight through groove that accommodates and limits the body portion 111. The limiting seat 21 is used to place the body portion 111 of the contact 11 and restrict the horizontal displacement of the contact 11. In use, the contact 11 can be placed from top to bottom onto the top of the limiting seat 21 and embedded into the limiting seat 21. After the contact 11 is placed, it will not shift in the horizontal direction. Moreover, since the top shape of the limiting seat 21 matches the shape of the contact 11, the retaining hole 1121 can be initially positioned after the contact 11 is placed.

[0047] The upper limit mechanism 22 includes an upper limit block 221 and a first drive device 222, such as Figure 11As shown, the bottom shape of the upper limit block 221 matches the top shape of the body 111. The first driving device 222 is connected to the upper limit block 221 and is used to drive the upper limit block 221 closer to and away from the limiting seat 21. After the contact 11 is placed on the limiting seat 21, the first driving device 222 can drive the upper limit block 221 closer to the limiting seat 21, and make the bottom of the upper limit block 221 as close as possible to the top of the body 111. At this time, the upper and lower sides of the contact 11 are blocked by the limiting seat 21 and the upper limit block 221, and will not move during subsequent processing. When it is necessary to remove the contact 11, the first driving device 222 can drive the upper limit block 221 away from the limiting seat 21 to release the restriction above the contact 11 so that the contact 11 can be removed.

[0048] In addition to the first fixing mechanism 2, the device also includes a clamping mechanism 3 for the auxiliary fixing contact 11, such as... Figure 11 As shown, the clamping mechanism 3 includes clamping blocks 31 and a second driving device 32. Two clamping blocks 31 are provided, located on opposite sides of the contact 11 and directly opposite the connecting portion 112 of the contact 11. The second driving device 32 horizontally drives the two clamping blocks 31 to simultaneously abut against or move away from the connecting portion 112. Corresponding to the clamping blocks 31, the second driving device 32 is a linear driving device, and two of them are also provided. The two second driving devices 32 are respectively located on the side of the two clamping blocks 31 away from the contact 11, and drive the two clamping blocks 31 respectively. After the first fixing mechanism 2 fixes the contact 11, the second driving device 32 in the clamping mechanism 3 can drive the two clamping blocks 31 closer together and simultaneously abut against the two connecting portions 112 on the contact 11, preventing the contact 11 from moving and even slightly reducing the distance d1 between the two connecting portions 112, facilitating the simultaneous insertion of the two connecting portions 112 into the snap ring 12 slot.

[0049] The clamping mechanism 3 has a clamping block 31 with a relief groove 311 on its top to avoid the retaining spring 12. The relief groove 311 passes through the side of the clamping block 31 facing the connecting part 112 and avoids the retaining hole 1121. The depth of the relief groove 311 is set according to the position of the retaining hole 1121 and the position of the clamping block 31 relative to the connecting part 112. Figure 19 , 20 As shown, when the clamping block 31 abuts against the connecting part 112 and the two ends of the retaining spring 12 are aligned with the retaining hole 1121, the bottom surface of the clearance groove 311 is preferably close to the retaining spring 12, which can play a certain positioning role for the retaining spring 12. After the retaining spring 12 is aligned with the retaining hole 1121, when the second fixing mechanism 4 moves away from the first fixing mechanism 2, it can play a role in assisting the retaining spring 12 and the second fixing mechanism 4 to separate from each other.

[0050] like Figure 12-16As shown, the second fixing mechanism 4 includes a fixing seat 41 and a third driving device 44. A strip-shaped groove 411 is provided on the side wall of the fixing seat 41. A cam 42 and two sliding blocks 43 are provided inside the groove 411. The cam 42 is rotatably connected to the fixing seat 41. The rotation axis of the cam 42 is horizontally arranged and perpendicular to the length direction of the groove 411. The two sliding blocks 43 are located on both sides of the cam 42 and are close to the cam 42. The two sliding blocks 43 are slidably connected to the fixing seat 41, and a fixing post 431 is protruding on the side away from the fixing seat 41. The third driving device 44 is used to drive the cam 42 to rotate. Before the second fixing mechanism 4 fixes the snap ring 12, two sliding blocks 43 can be slidably adjusted so that the fixing posts 431 on the two sliding blocks 43 are close to each other. Then, the snap ring 12 can be sleeved on the outside of the cam 42 and the fixing posts 431. Next, the cam 42 can be driven to rotate by the third driving device 44. Under the pressure of the cam 42, the two sliding blocks 43 move away from each other, causing the fixing posts 431 on them to move away from each other and abut against the inside of the snap ring 12, thereby fixing the snap ring 12.

[0051] The slide groove 411 is horizontally oriented along its length and perpendicular to the axis of the retaining hole 1121. Two fixing posts 431 are provided, which are adjusted horizontally along with the sliding block 43. In addition to the slide groove 411, a positioning groove 413 is also provided on the side of the fixing base 41. The positioning groove 413 is located on the same side as the slide groove 411 and directly above it. The positioning groove 413 avoids the retaining spring 12, and the side of the internal part facing away from the cam 42 is an arc surface 4131. The arc surface 4131 is coaxial with the cam 42 and its size matches that of the retaining spring 12. Through the positioning groove 413, the installation position of the retaining spring 12 can be positioned when fixing it. After the retaining spring 12 is fixed, it can prevent the retaining spring 12 from shifting relative to the fixing base 41, thus affecting the contact head 11. The positioning groove 413 is formed by the side plane of the fixed base 41 and the detachable positioning piece 412. When assembling snap rings 12 of different sizes, different positioning pieces 412 can be removed and replaced for adaptation.

[0052] The third driving device 44 includes a rack 441, a gear 442, and a cylinder 443. The gear 442 is coaxially arranged with the cam 42 and is fixedly connected to the cam 42. The cylinder 443 drives the rack 441 in the same direction as the length of the rack 441, and the rack 441 meshes with the gear 442. When the cylinder 443 operates, it can drive the rack 441 to move along its own length, thereby driving the gear 442 meshing with the rack 441 to rotate, causing the cam 42 to rotate synchronously with the gear 442. The cam 42 is preferably an elliptical cam 42, and the two sliding blocks 43 and their fixed posts 431 are symmetrically arranged on both sides of the cam 42. When fixing the retaining spring 12, the retaining spring 12 can be evenly stressed, resulting in a better fixing effect and less risk of damage to the retaining spring 12. The fixed posts 431 on the sliding blocks 43 are cylindrical, which makes it less likely to damage the retaining spring 12 during fixing. The length direction of the fixing post 431 is consistent with the rotation axis direction of the cam 42, which makes it easy to insert the retaining ring 12. After the retaining ring 12 is inserted, the length of the fixing post 431 should preferably extend to the front side of the retaining ring 12 for more stable subsequent fixation.

[0053] After the first fixing mechanism 2 fixes the contact 11 and the second fixing mechanism 4 fixes the retaining ring 12, the first fixing mechanism 2 and the second fixing mechanism 4 can be driven to move closer to each other through the insertion drive mechanism 5, thereby aligning the contact 11 and the retaining ring 12. In one embodiment, the insertion drive mechanism 5 includes a support frame 51, a horizontal drive device 52, and a vertical drive device 53. The support frame 51 is fixed relative to the first fixing mechanism 2. The horizontal drive device 52 is fixedly mounted on the support frame 51 and is driven by the vertical drive device 53. The driving direction of the horizontal drive device 52 is perpendicular to the axis of the retaining hole 1121. The vertical drive device 53 is driven by the second fixing mechanism 4.

[0054] After the snap ring 12 and the contact 11 are aligned with each other by the insertion drive mechanism 5, the distance d1 between the two connecting parts 112 can be widened by the distance widening mechanism 6, so that the two ends of the snap ring 12 can be inserted into the snap hole 1121, and the snap ring 12 can be tightly connected to the contact 11. Figure 17 , 18 As shown, the widening mechanism 6 includes a push rod 61 and a fourth driving device 62. The fourth driving device 62 is used to drive the push rod 61 horizontally, and the driving direction is perpendicular to the axis of the locking hole 1121. The length direction of the push rod 61 is consistent with the driving direction of the fourth driving device 62. One end of the push rod 61 is directly opposite the gap between the two connecting parts 112, and can be inserted into and widen the gap between the two connecting parts 112 as the fourth driving device 62 drives it. In use, the fourth driving device 62 is activated to drive the end of the push rod 61 into the gap between the two connecting parts 112, thereby widening the distance d1 between the two connecting parts 112.

[0055] In addition, the device is also equipped with an opening positioning mechanism 7, which includes a positioning rod 71 and a fifth driving device (not shown). The positioning rod 71 is located below the first fixing mechanism 2, and its top end faces the retaining ring 12 on the first fixing mechanism 2. The fifth driving device is used to drive the positioning rod 71 to rise and fall. The top end of the positioning rod 71 can pass through the opening 121 on the retaining ring 12, and the dimension d2 of the top end of the positioning rod 71 in the axial direction of the retaining hole 1121 is slightly smaller than the minimum distance d3 between the two ends of the retaining ring 12. After the retaining ring 12 is fitted onto the fixing seat 41, before the retaining ring 12 is fastened away from each other by the fixing post 431, the positioning rod 71 can be driven to rise and insert into the opening 121 on the retaining ring 12 by the fifth driving device. During the insertion process, the position of the opening 121 on the retaining ring 12 can be finely adjusted to ensure that the opening 121 is vertically downward so that the retaining ring 12 can be aligned with the contact 11 later.

[0056] Based on the above mechanisms, the assembly process of the contact assembly 1 is as follows: First, fix the contact 11 and the retaining ring 12 respectively. When fixing the contact 11, place the contact 11 on the top of the fixing seat 41 and limit the upper limit block 221 by driving the first driving device 222. Then, drive the clamping block 31 to abut against the contact 11 connection part 112 by the second driving device 32. When fixing the retaining ring 12, put the retaining ring 12 on the outside of the cam 42 and the fixing post 431, and drive the cam 42 to rotate by the third driving device 44 to tighten the retaining ring 12. During this process, if the retaining hole on the retaining ring 12 is not vertically downward, drive the positioning rod 71 by the fifth driving device to finely adjust the position of the opening 121 of the retaining ring 12. After the contact 11 and the retaining ring 12 are fixed, the horizontal drive device 52 and the vertical drive device 53 drive the fixing base 41 and its retaining ring 12 to approach the contact 11, so that the two connecting parts 112 on the contact 11 are inserted into the openings 121 on the retaining ring 12, aligning the two ends of the retaining ring 12 with the retaining holes 1121 on the two connecting parts 112. After alignment, the cam 42 on the second fixing mechanism 4 can be rotated to reset, releasing the retaining ring 12, and the insertion drive mechanism 5 drives the second fixing mechanism 4 away from the first fixing mechanism 2. With the limiting assistance of the clearance groove 311, the retaining ring 12 remains aligned with the retaining hole 1121. At the same time, the fourth drive device 62 can be activated to drive the push rod 61 to widen the distance d1 between the two connecting parts 112, so that the two ends of the retaining ring 12 are respectively inserted into the corresponding retaining holes 1121.

[0057] In summary, this equipment can automatically assemble the contact assembly 1. The assembled contact assembly 1 is tightly connected and not easily separated. Replacing manual assembly with this equipment can effectively improve assembly efficiency.
