Description

Technical Field

[0001] This application relates to the field of automated equipment technology, and in particular to a pressing head and pressing equipment including the same. Background Technology

[0002] In the production process of automotive wiring harness electrical boxes, electrical components such as fuses or relays need to be pressed into the corresponding terminals inside the electrical box. In recent years, wiring harness factories have frequently experienced problems such as deformation of the internal springs of automotive wiring harness electrical boxes due to rough installation by personnel. This can easily lead to functional failures during the assembly process at the OEM, resulting in serious quality accidents. To address these issues, automated electrical component pressing equipment has emerged. This equipment places the electrical components to be installed onto the corresponding terminals in the wiring harness electrical box, and the control system controls the pressing drive mechanism to press the electrical components into the terminals. After all the electrical components are pressed into the automotive wiring harness electrical box, a usable automotive wiring harness electrical box is obtained. The pressing head of the equipment presses the electronic components into the terminals in the electrical box, replacing the repetitive manual insertion work of the past and greatly improving production efficiency.

[0003] Currently, the pressing head of most pressing equipment has a fixed, small size for pressing all electrical components. However, since an automotive wiring harness electrical box often contains various electrical components such as fuses and relays, and these components vary in size, the pressing area on top of each component also varies. For example, a fuse is small, with a pressing area of ​​less than one square centimeter, while a relay, which has a larger dimensional tolerance, can have a pressing area of ​​several square centimeters. To accommodate the pressing of fuses, the contact area of ​​the pressing head of existing pressing equipment is relatively small. When pressing fuses, the limited contact area can easily lead to uneven pressure on the fuse, resulting in misalignment and tilting, causing terminal disengagement, circuit failure, and other quality problems. Utility Model Content

[0004] Therefore, the purpose of this invention is to overcome the shortcomings of existing pressing equipment, which has a small end size of the pressing head and cannot be well applied to the pressing of electrical components with large size deviations. This invention provides a pressing head and pressing equipment containing it. This invention can adapt to the pressing of electrical components with large size deviations, such as fuses and relays, improving the applicability of pressing different electrical components, reducing the occurrence of pressing accidents, and further improving the quality of pressing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A press head includes a fixed block, a first press head disposed at one end of the fixed block, and two second press heads disposed on both sides of the first press head, the two second press heads being connected to the fixed block by an opening and closing mechanism; it also includes a switching drive device connected to the opening and closing mechanism and used to drive the opening and closing mechanism to drive the two second press heads to perform opening and closing movements.

[0007] In use, this invention utilizes a switching drive device to activate the opening and closing mechanism, causing the two second pressing heads to open and close. When the two second pressing heads are closed, their ends align with the first pressing head on either side. At this time, the end size of the pressing head formed by the ends of the two second pressing heads is relatively large, making it suitable for electrical components with a large top pressing area, such as relays. When the two second pressing heads are open, the first pressing head can perform individual pressing operations. The end size of the first pressing head is relatively small, making it suitable for electrical components with a smaller top pressing area, such as fuses. The first pressing head and the two second pressing heads can be freely switched, allowing for the pressing of electrical components of various sizes, meeting the pressing requirements of electrical components of varying sizes in increasingly functional automotive wiring harness electrical boxes. This invention integrates two types of pressing heads with different end sizes using a switchable pressing head method, enabling it to adapt to the pressing of electrical components with large size variations, such as fuses and relays. This improves the applicability of pressing different electrical components, reduces the occurrence of pressing accidents, and further improves the quality of pressing.

[0008] Furthermore, the end of the first pressure head is a straight end, and the ends of the two second pressure heads are L-shaped ends. The L-shaped ends of the two second pressure heads are arranged opposite each other. When the two second pressure heads are closed, an accommodating space is formed between them, and the first pressure head is located in the accommodating space.

[0009] This invention designs the second pressure head to cover the first pressure head. On the one hand, the end of the second pressure head can approach the entire pressing surface without excessive structural gaps, thus ensuring better pressure transmission uniformity and improving the quality of pressing. On the other hand, this design is more compact. The pressure head needs to perform reciprocating pressing operations, and the gap space between it and the pressing guide template on the upper part of the electrical box being pressed is limited. Better compactness can reduce the risk of collision and scratch, which is more conducive to the safety of pressing and reduces the occurrence of pressing accidents.

[0010] Furthermore, clearance grooves for accommodating the first pressure head are provided on one side of each of the two second pressure heads. In this way, when the two second pressure heads are closed, the first pressure head is not only located within the accommodating space, but can also enter the clearance grooves on both sides. This makes the overall structure of the two second pressure heads after closure more compact with the first pressure head, and also controls the end area of ​​the two combined second pressure heads to a certain extent, allowing them to accommodate more electrical components.

[0011] Furthermore, the opening and closing mechanism includes two swing blocks, one end of which is fixedly connected to the two second pressure heads respectively, and the other end of the two swing blocks is rotatably connected to the fixed block through a first rotating shaft; it also includes a connecting block whose two ends are respectively connected to the two swing blocks; the output end of the switching drive device is connected to the connecting block and drives the connecting block to reciprocate, and the connecting block drives the two swing blocks to open and close around the first rotating shaft, and the fixed block is provided with a clearance portion for the two swing blocks to open and close.

[0012] The opening and closing mechanism of the two second pressure heads of this utility model adopts an arc-shaped swing on the reciprocating plane of the connecting block with the first rotating shaft as the axis. The output end of the switching drive device uses the connecting block connected to the two swing blocks as the force transmission point to push the two swing blocks to swing around the first rotating shaft. It can flexibly open and close together on both sides of the first pressure head, thereby switching with the first pressure head. The structure is simple and effective and the design is ingenious.

[0013] Furthermore, the clearance portion on the fixed block is provided on both sides and inside the fixed block, and one end of the swing block is housed inside the fixed block and passes through both sides of the fixed block when opening and closing.

[0014] Furthermore, the connecting block has symmetrically arranged second rotating shafts at both ends, and the swing block has an opening slot at its end. The second rotating shaft is confined within the opening slot. The axes of the first and second rotating shafts are parallel to each other and perpendicular to the opening and closing plane of the swing block. To ensure the assembly of each part and meet the interlocking relationship during movement, the opening slot is used to confine the second rotating shaft, which not only allows the movement of the connecting block to be transmitted to the swing block, but also facilitates the installation of the swing block and the connecting block.

[0015] Furthermore, the swing block is provided with an arc-shaped guide surface that slides against the fixed block, and the center of the arc-shaped guide surface is located on the axis of the first rotating shaft. During the rotation of the swing block around the first rotating shaft, the arc-shaped guide surface always slides against one side of the clearance portion of the fixed block, thus providing guidance, ensuring smooth swinging, and improving switching stability.

[0016] Furthermore, the switching drive device includes a telescopic cylinder fixedly connected to the fixed block, and the output end of the telescopic cylinder is connected to the connecting block.

[0017] Furthermore, the telescopic cylinder includes a cylinder body and a piston rod, with the output end being the piston rod. The cylinder body is connected to the fixing block for fixation, and the piston rod is connected to the connecting block for transmitting force and displacement.

[0018] Furthermore, it also includes a mounting base, on which the switching drive device is mounted. The mounting base can be used to mount the pressure head onto the pressing equipment to achieve the pressing purpose.

[0019] Furthermore, it also includes a force monitoring sensor located between the mounting base and the switching drive device. The force monitoring sensor can monitor the pressure during the pressing process, working in conjunction with the pressing equipment to detect whether the pressing process is normal. If excessive or insufficient pressure is detected, a pressing accident may occur, facilitating timely intervention.

[0020] This utility model also provides a pressing device, including the pressing head as described above. The pressing device generally includes a positioning module, a pressing module, an inspection module, and a control system. The pressing head is generally installed on the pressing module of the pressing device, and the multi-axis motion device of the pressing module drives the pressing head to move up and down to complete the pressing and insertion of electrical components of the automotive wiring harness electrical box one by one.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) When this utility model is used, the switching drive device drives the opening and closing mechanism to make the two second pressure heads open and close. When the two second pressure heads are closed, the ends of the two second pressure heads are arranged on both sides of the first pressure head. At this time, the end size of the pressure head composed of the ends of the two second pressure heads is relatively large, which can be used for electrical components with a large top pressing area, such as relays. When the two second pressure heads are open, the first pressure head can perform a separate pressing operation. The end size of the first pressure head is relatively small, which can be used for electrical components with a small top pressing area, such as fuses. The first pressure head and the two second pressure heads can be freely switched, so as to press electrical components of various sizes, and meet the pressing of electrical components of different sizes in automotive wiring harness electrical boxes with increasingly more functions.

[0023] (2) This utility model integrates two types of end size specifications by using a switchable press head, which can adapt to the press-fitting of electrical components with large size deviations, such as fuses and relays, improve the applicability of press-fitting of different electrical components, reduce the occurrence of press-fitting accidents, and further improve the quality of press-fitting.

[0034] Example 1

[0035] like Figure 1 and Figure 2As shown, a press head includes a fixed block 1, a first press head 2 disposed at one end of the fixed block 1, and two second press heads 3 disposed on both sides of the first press head 2. The two second press heads 3 are connected to the fixed block 1 through an opening and closing mechanism 4. It also includes a switching drive device 5 connected to the opening and closing mechanism 4 and used to drive the opening and closing mechanism 4 to drive the two second press heads 3 to perform opening and closing movements.

[0036] like Figure 3 and Figure 4 As shown, the end of the first pressure head 2 is a straight end, and the ends of the two second pressure heads 3 are L-shaped ends. The L-shaped ends of the two second pressure heads 3 are arranged opposite each other. When the two second pressure heads 3 are closed, a receiving space 30 is formed between them, and the first pressure head 2 is located in the receiving space 30.

[0037] In this embodiment, the second pressure head 3 is designed to cover the first pressure head 2. On the one hand, the end of the second pressure head 3 can approach the entire pressing surface without excessive structural gaps, thus ensuring better pressure transmission uniformity during pressing and improving the quality of pressing. On the other hand, this design is more compact. The pressure head needs to perform reciprocating pressing operations, and the gap space between it and the pressing guide template on the upper part of the electrical box being pressed is limited. Better compactness can reduce the risk of collision and scratch, which is more conducive to the safety of pressing and reduces the occurrence of pressing accidents.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the two second pressure heads 3 are also provided with clearance grooves 31 on opposite sides for accommodating the first pressure head 2. In this way, when the two second pressure heads 3 are closed, the first pressure head 2 is not only located within the accommodating space 30, but can also enter the clearance grooves 31 on both sides. This makes the overall structure of the two second pressure heads 3 and the first pressure head 2 more compact after closure, and also controls the end area of ​​the two combined second pressure heads 3 to a certain extent, so that it can accommodate more electrical components.

[0039] like Figure 5 and Figure 6 As shown, the opening and closing mechanism 4 includes two swing blocks 41 with one end fixedly connected to two second pressure heads 3 respectively, and the other end of the two swing blocks 41 is rotatably connected to the fixed block 1 through the first rotating shaft 42; it also includes a connecting block 43 with both ends connected to the two swing blocks 41 respectively; the output end of the switching drive device 5 is connected to the connecting block 43 and drives the connecting block 43 to reciprocate, and the connecting block 43 drives the two swing blocks 41 to open and close around the first rotating shaft 42. The fixed block 1 is provided with a clearance part 10 for the two swing blocks 41 to open and close.

[0040] In this embodiment, the opening and closing of the two second pressure heads 3 is based on the first rotating shaft 42 as the axis. The two second pressure heads 3 swing in an arc on the reciprocating plane of the connecting block 43. The output end of the switching drive device 5 uses the connecting block 43 connected to the two swing blocks 41 as the force transmission point to push the two swing blocks 41 to swing around the first rotating shaft 42. This allows them to flexibly open and close together on both sides of the first pressure head 2, thereby switching with the first pressure head 2. The structure is simple and effective, and the design is ingenious.

[0041] like Figure 5 As shown, the clearance portion 10 on the fixed block 1 is provided on both sides and inside the fixed block 1, and one end of the swing block 41 is housed inside the fixed block 1 and passes through both sides of the fixed block 1 when opening and closing.

[0042] like Figure 5 and Figure 6 As shown, the connecting block 43 has symmetrically arranged second rotating shafts 44 at both ends, and the swing block 41 has an opening slot 411 at its end. The second rotating shafts 44 are limited in the opening slots 411. The axes of the first rotating shaft 42 and the second rotating shaft 44 are parallel to each other, and the axes of the first rotating shaft 42 and the second rotating shaft 44 are perpendicular to the opening and closing plane of the swing block 41. In order to ensure the assembly of each part and meet the interlocking relationship during movement, the opening slots 411 are used to limit the second rotating shafts 44, which can both transmit the movement of the connecting block 43 to the swing block 41 and facilitate the installation of the swing block 41 and the connecting block 43.

[0043] like Figure 5 and Figure 6 As shown, the swing block 41 is provided with an arc-shaped guide surface 412 that slides against the fixed block 1, and the center of the arc-shaped guide surface 412 is located on the axis of the first rotating shaft 42. During the rotation of the swing block 41 around the first rotating shaft 42, the arc-shaped guide surface 412 always slides against one side of the clearance part 10 of the fixed block 1, which can play a guiding role, while ensuring the smoothness of the swing and improving the switching stability.

[0044] In this embodiment, the switching drive device 5 includes a telescopic cylinder that is fixedly connected to the fixed block 1, and the output end of the telescopic cylinder is connected to the connecting block 43.

[0045] like Figure 5 and Figure 6 As shown, the telescopic cylinder includes a cylinder body 51 and a piston rod 52. The output end is the piston rod 52. The cylinder body 51 is connected to the fixing block 1 for fixation, and the piston rod 52 is connected to the connecting block 43 for transmitting force and displacement.

[0046] The working principle of this embodiment is as follows: In use, the switching drive device 5 drives the opening and closing mechanism 4 to open and close the two second pressing heads 3. When the two second pressing heads 3 are closed, the ends of the two second pressing heads 3 are positioned on both sides of the first pressing head 2. At this time, the end size of the pressing head composed of the ends of the two second pressing heads 3 is relatively large, which can be used for electrical components with a large top pressing area, such as relays. When the two second pressing heads 3 are open, the first pressing head 2 can perform a separate pressing operation. The end size of the first pressing head 2 is relatively small, which can be used for electrical components with a small top pressing area, such as fuses. The first pressing head 2 and the two second pressing heads 3 can be freely switched, thereby being used to press electrical components of various sizes, meeting the pressing needs of electrical components of different sizes in automotive wiring harness electrical boxes with increasingly more functions.

[0047] The advantage of this embodiment is that it integrates two end size specifications of press heads by using a switchable press head method, which can adapt to the press-fitting of electrical components with large size deviations, such as fuses and relays, improves the applicability of press-fitting different electrical components, reduces the occurrence of press-fitting accidents, and further improves the quality of press-fitting.

[0050] like Figure 1 and Figure 2 As shown, it also includes a mounting base 6, on which the switching drive device 5 is mounted. The mounting base 6 can be used to mount the pressure head onto the pressing equipment to achieve the pressing purpose.

[0051] like Figure 1 and Figure 2 As shown, it also includes a force monitoring sensor 7 located between the mounting base 6 and the switching drive device 5.

[0052] The force monitoring sensor 7 can monitor the pressure during the pressing process. It is used in conjunction with the pressing equipment to detect whether the pressing process is normal. If the pressure is found to be too high or too low, a pressing accident may occur, which can facilitate timely intervention.

[0053] The other structures and principles of this embodiment are the same as those of Embodiment 1.
