Description

Technical Field

[0001] This invention relates to the field of relay manufacturing technology, specifically to a relay core riveting device and its working method. Background Technology

[0002] The core riveting of a relay refers to the operation of fixing the core of the relay to the body of the relay using rivets or bolts. The core of a relay usually consists of a core holder and windings. The core holder needs to be connected to the relay body to ensure the stability of the core position so that the relay can work normally.

[0003] First, select suitable rivets or bolts. The materials used should match the relay body and the iron core base. Then, place the iron core base in the corresponding position on the relay body and use a riveting gun or other appropriate tools to rivet the two parts together.

[0004] For example, the patent application with application number 202210188446.6 discloses a relay core riveting device, and specifically discloses that the riveting device includes a riveting feeding mechanism, a riveting mechanism and a positioning mechanism, so as to realize the direct riveting of the core seat and the relay body.

[0005] When riveting the iron core base and the relay body, it is necessary to pay attention to the uniformity of force to avoid damaging the relay due to excessive force, resulting in a loose connection. At the same time, the iron core base is mostly made of plastic. When there is a difference in the thickness of the iron core base, it will cause uneven force on the iron core base when the riveting mechanism presses down, causing the iron core base to crack and thus affecting the quality of the iron core base. Summary of the Invention

[0006] The purpose of this invention is to provide a relay core riveting device and its working method.

[0007] The technical problem solved by this invention is to solve the problem in the prior art that the relay is damaged due to excessive force when riveting the iron core base and the relay body, resulting in a loose connection.

[0008] The present invention can be achieved through the following technical solution: a relay core riveting device, comprising an intermediate limiting component for clamping an electromagnet, an upper riveting control component for riveting a plastic top plate onto the electromagnet, and a lower riveting control component for riveting a plastic base plate and a metal base onto the electromagnet. The upper and lower riveting control components cooperate with the intermediate limiting component to limit the electromagnet, and the upper and lower riveting control components work together.

[0009] A further technical improvement of the present invention is that: the upper riveting control component includes a first clamping plate and a second clamping plate for clamping the plastic top plate, the longitudinal distance between the first clamping plate and the second clamping plate is adjustable, and a distance detection sensor is provided between the first clamping plate and the second clamping plate.

[0010] A further technical improvement of the present invention is that the upper riveting control assembly further includes a first mating plate and a second mating plate for clamping the plastic top plate. The longitudinal distance between the first mating plate and the second mating plate is adjustable, and the lateral distance between the first mating plate and the first clamping plate is adjustable, as is the lateral distance between the second mating plate and the second clamping plate.

[0011] A further technical improvement of the present invention is that: the first clamping plate is fixedly installed on the first base, the second clamping plate is fixedly installed on the second base, and the distance between the first base and the second base is adjustable by means of the clamping telescopic rod.

[0012] A further technical improvement of the present invention is that: a fixed base is fixedly connected to the first clamping plate, and a movable base is fixedly connected to the first mating plate, and the fixed base and the movable base are adjustable by adjusting the telescopic rod.

[0013] A further technical improvement of the present invention is that the upper riveting control component and the lower riveting control component have the same structure.

[0014] A further technical improvement of the present invention is that: the intermediate limiting component includes a limiting sleeve, the limiting sleeve is fixedly installed on the limiting rod, and the limiting sleeve is installed at the output end of the limiting cylinder. Clamping cylinders are symmetrically fixed at both ends of the limiting rod, and a supporting top plate is provided at the output end of the clamping cylinder.

[0015] A further technical improvement of the present invention is that: an end receiving component is provided on the side of the upper riveting control component, the end receiving component includes a receiving base, and the receiving base is provided with receiving grooves for cooperating with the first clamping plate and the second clamping plate respectively.

[0016] A further technical improvement of the present invention is that the fixed end of the lower riveting control component is mounted on the adjustment plate, and the longitudinal height of the adjustment plate is adjustable.

[0017] A method for operating a relay core riveting device includes the following steps:

[0018] Step 1: Clamp the electromagnet between the upper riveting control component and the lower riveting control component;

[0019] Step 2: Use the lower riveting control component to place the plastic base plate and metal base on the bottom of the electromagnet, clamp and fix the plastic base plate and metal base, and use the lower riveting control component to obtain the bonding thickness of the plastic base plate and metal base;

[0020] Step 3: Use the upper riveting control component to place the plastic top plate on the electromagnet to clamp and fix the plastic top plate, and use the upper riveting control component to obtain the thickness of the plastic top plate.

[0021] Step 4: Simultaneously activate the first and second riveting devices to rivet both ends of the electromagnet at the same time.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This application uses an intermediate limiting component to clamp and fix the electromagnet, then uses an upper riveting control component to limit the plastic top plate, and uses a lower riveting control component, plastic bottom plate, and metal base for further limiting. This is to ensure that when the two ends of the electromagnet are riveted, the upper and lower riveting control components can support the plastic plate, preventing deformation of the center of the plastic plate due to excessive riveting force. At the same time, because the intermediate limiting component supports the electromagnet, it can support and limit the electromagnet and plastic top plate during this process, preventing damage to the relay due to excessive force.

[0024] 2. This application, by providing a first clamping plate and a second clamping plate, with the longitudinal distance between the first clamping plate and the second clamping plate adjustable, allows the plastic top plate to be placed between the first clamping plate and the second clamping plate, thereby limiting the position of the plastic top plate. At the same time, since a distance detection sensor is set between the first clamping plate and the second clamping plate, the thickness of the plastic top plate can be measured. Based on the thickness of the plastic top plate, the riveting pressure that it can withstand can be determined, which facilitates dynamic adjustment of the riveting pressure according to the thickness of the plastic top plate. This solves the problem of uneven stress on the iron core seat and cracking of the iron core seat in the prior art.

[0025] 3. In this application, by setting a first mating plate and a second mating plate, the longitudinal distance between the first mating plate and the second mating plate is adjustable, and the lateral distance between the first mating plate and the second clamping plate is adjustable. This can be adjusted according to the size of the plastic top plate, so that the plastic top plate can be fully clamped, avoiding the plastic top plate from moving during riveting, ensuring the stability of the plastic top plate during riveting, and thus ensuring the riveting accuracy.

[0026] 4. In this application, by setting an end receiving component on the side of the upper riveting control component, the receiving groove is used to receive the first clamping plate and the second clamping plate. Thus, when the riveting pressure is applied to the plastic top plate, the stability of the first clamping plate and the second clamping plate is ensured, thereby ensuring the stability of the plastic top plate during riveting, reducing the deformation of the plastic top plate, and thus reducing the possibility of cracking of the iron core seat.

[0027] 5. This application mounts the fixed end of the lower riveting control component on the adjustment plate, and the vertical height of the adjustment plate is adjustable, thereby enabling the distance between the lower riveting control component and the upper riveting control component to be adjustable, which facilitates the loading and unloading of the electromagnet.

[0035] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] Please see Figure 1As shown, when manufacturing a relay, the relay includes an electromagnet 101. A plastic base plate 109 is provided at the first end of the electromagnet 101, and a metal base 1011 is provided on the side of the plastic base plate 109 away from the electromagnet 101. When riveting the electromagnet 101, the plastic base plate 109 and the metal base 1011, a bottom riveting metal 1010 is used for riveting. In this process, the plastic base plate 109 is tightly attached to the bottom of the electromagnet 101, and then the metal base 1011 is placed on the plastic base plate 109. The bottom riveting metal 1010 is used to rivet the plastic base plate 109, the metal base 1011 and the electromagnet 101 together to fix their relative positions.

[0037] Then, a plastic top plate 106 is installed on the side of the electromagnet 101 away from the plastic base plate 109. The plastic top plate 106 and the electromagnet 101 are riveted together by the top riveting metal 105. At the same time, a second contact 108 is fixedly installed on the side of the plastic top plate 106, and a first contact 107 is provided on the side of the second contact 108.

[0038] A metal connecting plate 102 is welded to the side of the metal base 1011. A metal rotating plate 104 is rotatably disposed at the end of the metal connecting plate 102. The end of the metal rotating plate 104 cooperates with the first contact 107 and the second contact 108 respectively to realize the opening and closing of the circuit. The metal connecting plate 102 and the metal rotating plate 104 are fixedly connected by a spring sheet 103.

[0039] Please see Figure 1-5 As shown, a relay core riveting device includes an upper riveting control component 1 for riveting a plastic top plate 106 and an electromagnet 101, a lower riveting control component 3 for riveting a plastic bottom plate 109, a metal base 1011, and an electromagnet 101, and an intermediate limiting component 2 for fixing and supporting the position of the electromagnet 101. In use, the upper riveting control component 1, the lower riveting control component 3, and the intermediate limiting component 2 work together to limit the position of the plastic bottom plate 109, the metal base 1011, the electromagnet 101, and the plastic top plate 106, thereby facilitating their riveting.

[0040] In this application, the upper riveting control component 1 and the lower riveting control component 3 have the same structure, so this application will disclose the upper riveting control component 1 as an example.

[0041] Specifically, the upper riveting control assembly 1 includes a first clamping plate 19 and a second clamping plate 110 for clamping the plastic top plate 106. The first clamping plate 19 and the second clamping plate 110 move towards each other to clamp the plastic top plate 106. At the same time, a first mating plate 111 and a second mating plate 112 are provided on the sides of the first clamping plate 19 and the second clamping plate 110. The first clamping plate 19 and the first mating plate 111 are mated, and the second clamping plate 110 and the second mating plate 112 are mated. In this application, the distance between the first clamping plate 19 and the first mating plate 111 is adjustable, and the distance between the second clamping plate 110 and the second mating plate 112 is also adjustable.

[0042] In this application, the first clamping plate 19 and the first mating plate 111 are first moved towards each other to move the plastic top plate 106 above it. At the same time, the second clamping plate 110 and the second mating plate 112 are moved towards each other to move the plastic top plate 106 below it. This achieves the engagement of the first clamping plate 19, the first mating plate 111 with the top riveting metal 105, and the engagement of the second clamping plate 110 and the second mating plate 112 with the shape of the electromagnet 101. Then, the first clamping plate 19 and the second clamping plate 110 are moved towards each other, and the first mating plate 111 and the second mating plate 112 are moved towards each other to achieve the clamping effect on the plastic top plate 106.

[0043] As a further embodiment of this application, riveting grooves 18 are provided on the first clamping plate 19, the second clamping plate 110, the first mating plate 111, and the second mating plate 112 for mating with the top riveting metal 105 and the electromagnet 101. A distance detection sensor 10 is provided between the first clamping plate 19 and the second clamping plate 110 to detect the distance between the first clamping plate 19 and the second clamping plate 110, thereby obtaining the thickness of the plastic top plate 106. The pressing depth and pressure of the first riveting device 4 are adjusted according to the thickness of the plastic top plate 106 to avoid the plastic top plate 106 from cracking due to excessive pressing pressure or depth of the first riveting device 4, thus ensuring the quality of the plastic top plate 106.

[0044] To enable the first clamping plate 19 and the second clamping plate 110 to move towards or away from each other, and to enable the first mating plate 111 and the second mating plate 112 to move towards or away from each other, a moving mechanism is used for control. Taking the first clamping plate 19 and the second clamping plate 110 as an example, a first base 11 is fixed to the end of the first clamping plate 19, a clamping telescopic rod 12 is fixed to the first base 11, and a second base 15 is fixed to the end of the clamping telescopic rod 12. The second base 15 and the second clamping plate 110 are fixedly connected. A side slider is fixed on the side of the second base 15, and a back slide groove 113 is provided on the side of the mounting slide plate 14, wherein the side slider and the back slide groove 113 are slidably connected; when the first clamping plate 19 and the second clamping plate 110 move towards each other or away from each other, the second base 15 is pushed to move longitudinally by activating the clamping telescopic rod 12. At this time, the side slider slides inside the back slide groove 113, thereby realizing the relative longitudinal movement of the first clamping plate 19 and the second clamping plate 110, thereby enabling the thickness measurement of the plastic top plate 106.

[0045] To adjust the distance between the first clamping plate 19 and the first mating plate 111, and to adjust the distance between the second clamping plate 110 and the second mating plate 112, taking the first clamping plate 19 as an example, a mounting slide plate 14 is fixed to the side of the first clamping plate 19 via a first base 11, a fixed base 16 is fixed to the side of the mounting slide plate 14, and a movable base 17 is fixed to the side of the first mating plate 111 via the mounting slide plate 14. An adjusting telescopic rod 13 is fixed between the fixed base 16 and the movable base 17. In use, by activating the adjusting telescopic rod 13, the movable base 17 is moved, thereby adjusting the distance between the first clamping plate 19 and the first mating plate 111, and adjusting the distance between the second clamping plate 110 and the second mating plate 112.

[0046] The intermediate limiting assembly 2 includes a limiting rod 23, on which a clamping sleeve is fixed. The clamping sleeve is installed at the output end of the limiting cylinder 24. The activation of the limiting cylinder 24 controls the movement of the limiting rod 23 and the clamping sleeve towards the electromagnet 101, thus supporting the electromagnet 101. At this time, clamping cylinders 22 are symmetrically fixed at both ends of the limiting rod 23. A support plate 21 for supporting the bottom of the plastic top plate 106 is provided at the output end of the clamping cylinder 22. Therefore, during use, the activation of the clamping cylinder 22 is required to support the bottom of the plastic top plate 106, thereby ensuring that the electromagnet 101 does not deform. Specifically, during use, the first clamping plate 19, the second clamping plate 110, the first mating plate 111, and the second mating plate 112 are used to support the plastic top plate 106. 6. Positioning and support are defined, and the supporting top plate 21 presses against the end of the plastic top plate 106 to ensure that both the plastic top plate 106 and the electromagnet 101 are supported. During riveting, the force borne by the plastic top plate 106 is within its tolerance range. At the same time, the supporting top plate 21 and the limiting rod 23 support the electromagnet 101 to prevent deformation of the electromagnet 101 during riveting. As a further embodiment of this application, the symmetrically arranged upper riveting control component 1 and lower riveting control component 3 enable simultaneous riveting operations on both sides of the electromagnet 101. This avoids the need to readjust the angle of the electromagnet 101 when it is flipped, thus ensuring the accuracy of riveting the electromagnet 101.

[0047] A first riveting device 4 is provided on the upper riveting control component 1, and a second riveting device 6 is provided below the lower riveting control component 3. The height of the second riveting device 6 and the lower riveting control component 3 relative to the upper riveting control component 1 is adjustable. This is used to perform riveting operations on electromagnets 101 of different sizes and to facilitate the unloading of electromagnets 101 after riveting.

[0048] In this application, the second riveting device 6 is installed on the position adjustment base 7, which is L-shaped. An adjustment plate 9 is fixed at the end of the position adjustment base 7. The adjustment plate 9 is fixedly connected to the fixed base 16 and is installed at the output end of the lead screw assembly 8. The adjustment plate 9 is moved longitudinally by starting the lead screw assembly 8, thereby adjusting the longitudinal position of the position adjustment base 7. This adjusts the height of the second riveting device 6 and the lower riveting control assembly 3, making it suitable for electromagnets 101 of different sizes and facilitating the unloading of the electromagnets 101 after riveting.

[0049] In order to limit the ends of the first clamping plate 19, the second clamping plate 110, the first mating plate 111, and the second mating plate 112, and to prevent the ends of the first clamping plate 19, the second clamping plate 110, the first mating plate 111, and the second mating plate 112 away from the first base 11 from being lifted, an end receiving component 5 is provided at their ends.

[0050] The end receiving assembly 5 includes a receiving base 52, on which a receiving groove 51 is provided for mating. The receiving base 52 is M-shaped and placed laterally. In use, when the first clamping plate 19, the second clamping plate 110, the first mating plate 111, and the second mating plate 112 move, their ends move into the receiving groove 51, thereby limiting their movement.

[0051] In use, the electromagnet 101 is first placed inside the intermediate limiting assembly 2. The limiting cylinder 24 is activated, pushing the limiting rod 23 to move. The limiting rod 23 and the limiting sleeve provide initial limiting for the electromagnet 101. Then, the plastic base plate 109 and the metal base 1011 are placed between the first clamping plate 19 and the second clamping plate 110 on the lower riveting control assembly 3. The first clamping plate 19 and the second clamping plate 110 then secure the plastic base plate 109 and the metal base 1011. The thickness of the base 1011 is obtained to define the position of the plastic base plate 109 and the metal base 1011. Then, the lower riveting control component 3 is moved upward so that the plastic base plate 109 contacts the bottom of the electromagnet 101, achieving initial contact between the electromagnet 101 and the plastic base plate 109. At this time, the limiting rod 23 releases its clamping action on the electromagnet 101, so that the electromagnet 101 is pressed on the second clamping plate 110 under the limiting action of the limiting rod 23 and its own gravity.

[0052] Then, the plastic top plate 106 is placed between the first clamping plate 19 and the second clamping plate 110 of the upper riveting control component 1. Then, the vertical movement of the lower riveting control component 3 drives the electromagnet 101 to move upward until the electromagnet 101 contacts the second clamping plate 110 of the upper riveting control component 1. At this time, the plastic top plate 106 is clamped by the opposite movement of the first clamping plate 19 and the second clamping plate 110. The thickness of the plastic top plate 106 is determined. At this time, the electromagnet 101 continues to move upward so that the electromagnet 101 is in close contact with the second clamping plate 110 of the upper riveting control component 1.

[0053] At this point, the clamping and fixing of each component is achieved. The limiting cylinder 24 is activated to clamp the limiting sleeve onto the electromagnet 101. Then, the clamping cylinder 22 is activated to press the supporting top plate 21 tightly against the plastic top plate 106 and the plastic bottom plate 109 respectively, thus fully limiting the position of the relevant components.

[0054] Subsequently, by moving the relative positions of the first clamping plate 19 and the first mating plate 111, and by moving the relative positions of the second clamping plate 110 and the second mating plate 112, the riveting positions of the bottom riveting metal 1010 and the top riveting metal 105 using the riveting groove 18 are cleared.

[0055] Based on the obtained thickness of the plastic top plate 106 and the plastic bottom plate 109, the pressure when the first riveting device 4 and the second riveting device 6 are started is controlled to avoid the problem of plastic plate breakage caused by uneven thickness of the plastic top plate 106 and the plastic bottom plate 109, and to ensure the quality of the plastic top plate 106 and the plastic bottom plate 109. In this application, based on the suspension of the electromagnet 101, both ends of the electromagnet 101 can be riveted at the same time, avoiding the flipping of the electromagnet 101, ensuring the stability of the electromagnet 101 during riveting, and thus ensuring the riveting quality of the electromagnet 101.

[0056] A method for operating a relay riveting device includes:

[0057] Step 1: Place electromagnet 101 inside the intermediate limiting component 2. Activate the limiting cylinder 24 to push the limiting rod 23 to move. The limiting rod 23 and the limiting sleeve will then be used to achieve the initial limiting effect on electromagnet 101.

[0058] Step 2: Place the plastic base plate 109 and the metal base 1011 between the first clamping plate 19 and the second clamping plate 110 on the lower riveting control assembly 3. Use the first clamping plate 19 and the second clamping plate 110 to obtain the thickness of the plastic base plate 109 and the metal base 1011, thereby defining the position of the plastic base plate 109 and the metal base 1011.

[0059] Step 3: Move the lower riveting control component 3 upward so that the plastic base plate 109 contacts the bottom of the electromagnet 101, achieving initial contact between the electromagnet 101 and the plastic base plate 109. At this time, the limiting rod 23 releases its clamping action on the electromagnet 101, so that the electromagnet 101 is pressed on the second clamping plate 110 under the limiting action of the limiting rod 23 and its own gravity.

[0060] Step 4: Place the plastic top plate 106 between the first clamping plate 19 and the second clamping plate 110 of the upper riveting control component 1. Then, use the longitudinal movement of the lower riveting control component 3 to drive the electromagnet 101 to move upward until the electromagnet 101 contacts the second clamping plate 110 of the upper riveting control component 1. Use the opposite movement of the first clamping plate 19 and the second clamping plate 110 to clamp the plastic top plate 106 and determine the thickness of the plastic top plate 106.

[0061] Step 5: Using the continued upward movement of electromagnet 101, make electromagnet 101 stick tightly to the second clamping plate 110 of the upper riveting control assembly 1;

[0062] Step 6: Using the limit cylinder 24 to start, the limit sleeve is clamped on the electromagnet 101. Then, using the clamping cylinder 22 to start, the support top plate 21 is pressed tightly against the plastic top plate 106 and the plastic bottom plate 109 respectively, thus fully limiting the position of the relevant components.

[0063] Step 7: By moving the relative positions of the first clamping plate 19 and the first mating plate 111, and by moving the relative positions of the second clamping plate 110 and the second mating plate 112, the riveting positions of the bottom riveting metal 1010 and the top riveting metal 105 using the riveting groove 18 are made available.

[0064] Step 8: Based on the thickness of the obtained plastic top plate 106 and plastic bottom plate 109, control the pressure when the first riveting device 4 and the second riveting device 6 are started. Since the electromagnet 101 is suspended, both ends of the electromagnet 101 can be riveted at the same time.
