Description

Technical Field

[0001] The utility model relates to the technical field of programming, and more specifically, to a programming device and a production line provided with the programming device. Background Art

[0002] The production of the control boosting device of a subcutaneous electronic syringe includes a production process of processing and programming a printed circuit board (PCBA). Currently, a programming device is used to process and program the printed circuit board. Before processing and programming, the printed circuit board is first placed on a dedicated programming rack customized on the programming device, and then a corresponding programmer is selected according to the chip signal of the printed circuit board. Among them, the programmer is electrically connected to the probe assembly; finally, the driving mechanism of the programming device drives the probe assembly to move towards the programming rack until the probe assembly is in electrical contact with the programming site on the printed circuit board, so that the programmer can process and program the printed circuit board through the probe assembly.

[0003] However, the existing programming device has the following deficiencies: when changing the model of the printed circuit board (such as the end of the product life cycle of the control boosting device of a subcutaneous electronic syringe, iterative production suspension, temporary production change, etc.), it is necessary to replace the programming rack and the probe assembly, which leads to the need to re-customize the programming rack, resulting in high product production costs. Moreover, when waiting for the newly customized programming rack, it will also extend the product production cycle; furthermore, when replacing the programming rack of most existing programming devices, some mechanisms around the programming rack need to be removed, thus increasing the risk of damage to the programming device and the difficulty of replacing the programming rack, and affecting the product production efficiency. Summary of the Invention

[0004] The main purpose of the utility model is to provide a programming device with strong practicability, wide application range and low use cost.

[0005] Another purpose of the utility model is to provide a production line provided with the above-mentioned programming device.

[0006] To achieve the main object of the present utility model, the present utility model provides a programming device, comprising a frame, a needle board, a programmer and a pressing mechanism. The frame includes a frame body and a carrier table. The frame body is installed on the top of the carrier table. The needle board is detachably installed on the top of the carrier table. The needle board is provided with a probe assembly. The programmer is installed on the carrier table and is electrically connected to the probe assembly. The pressing mechanism includes a driving unit and a pressing plate. The driving unit is installed on the frame body. The pressing plate is provided with a thimble assembly. The driving unit can drive the pressing plate to move relative to the needle board in the height direction of the frame. Wherein, the programming device further includes a bracket and a transfer turntable. The bracket is installed on the frame. The bracket is provided with a first receiving position. The bottom of the first receiving position is provided with a first avoidance opening penetrating the bracket. The first avoidance opening is arranged opposite to the probe assembly. The transfer turntable is provided with a second receiving position. The bottom of the second receiving position is provided with a second avoidance opening penetrating the transfer turntable. The transfer turntable is detachably placed in the first receiving position. The second avoidance opening is arranged opposite to the probe assembly. The pressing plate can press the transfer turntable against the bracket.

[0007] As can be seen from the above, the transfer turntable is used to carry the printed circuit board to be programmed, and the transfer turntable can be a carrier or fixture used for turning and processing the printed circuit board during the production process. As long as the outer contour dimensions of different transfer turntables suitable for different models of printed circuit boards are basically the same, when changing the model of the printed circuit board to be programmed, the programming device can process and program different models of printed circuit boards only by replacing the transfer turntable, the needle board and the pressing plate; by using the combination of the bracket and the transfer turntable to replace the existing programming rack, the programming device has higher use flexibility and stronger practicability. And when changing the model of the printed circuit board, directly install the transfer turntable used in the turning and / or processing process of the printed circuit board onto the bracket, thus eliminating the need to re-customize a special carrier plate for processing and programming the printed circuit board, effectively reducing the production cost, facilitating shortening the production cycle of the product and improving the production efficiency.

[0008] A preferred solution is that the frame body and / or the carrier table are / is provided with a guide post group parallel to the height direction. The bracket is slidably installed on the guide post group; the frame further includes a first elastic buffer. The first elastic buffer forces the bracket to slide away from the needle board. The pressing plate can push the bracket and the transfer turntable towards the needle board.

[0009] As can be seen from the above, by setting the bracket to be slidable, it is beneficial to improve the reliability and stability of the contact between the probe assembly and the programming sites on the printed circuit board; and the setting of the first elastic buffer can buffer when the printed circuit board placed on the bracket contacts the probe assembly, avoiding direct hard contact between the probe assembly and the programming sites of the printed circuit board, thus playing a protective role for the probe assembly and the printed circuit board.

[0010] A further solution is that the pressing-down mechanism further includes a sliding plate, which is slidably mounted on the guide post group. The pressing plate is detachably connected to the sliding plate, and the driving unit is connected to the pressing plate or the sliding plate. The sliding plate is provided with positioning pins parallel to the height direction, and the turntable is provided with positioning holes, and the positioning pins can be inserted into the positioning holes.

[0011] As can be seen from the above, the setting of the sliding plate can improve the smoothness of the driving unit driving the pressing plate to move, and ensure that the thimble assembly on the pressing plate can be more accurately pressed on the preset pressing site on the printed circuit board, thereby ensuring the stability and reliability of the processing and burning; the design of the positioning pins on the sliding plate and the positioning holes on the turntable can also ensure the relative position accuracy between the printed circuit board, the probe assembly and the thimble assembly.

[0012] A further solution is that the positioning pin is slidably connected to the sliding plate. When the positioning pin is in a non-contact state, the first distance between the bottom of the positioning pin and the bracket is less than the second distance between the bottom of the thimble assembly and the bracket. The pressing-down mechanism further includes a second elastic buffer, and the second elastic buffer forces the positioning pin to slide towards the bracket.

[0013] As can be seen from the above, by setting the positioning pin to be slidable relative to the sliding plate, it can be ensured that when the thimble assembly abuts against the printed circuit board to fix the printed circuit board, the positioning pin can position and limit the turntable; the second elastic buffer can buffer the positioning pin when the positioning pin contacts the bracket or the turntable, avoiding direct hard contact between the positioning pin and the bracket or the turntable.

[0014] A further solution is that the driving unit includes a fixed seat, a handle, a sliding rod and a connecting rod. The fixed seat is installed on the frame. The handle has a connecting part and an operating part. The connecting part is hinged to the fixed seat. The sliding rod is slidably connected to the fixed seat in the height direction. The connecting rod is hinged between the connecting part and the sliding rod, and the handle can drive the sliding rod to slide through the connecting rod; or the driving unit is a linear slide table, an electric cylinder or a cylinder.

[0015] As can be seen from the above, the driving unit can be set to be manual or automatic according to usage requirements, usage conditions, production costs, etc., thereby improving the practicability and design flexibility of the burning equipment and expanding the applicable range of the burning equipment.

[0016] A further solution is that the frame further includes a third elastic buffer, and the third elastic buffer forces the bracket to slide towards the needle plate.

[0017] As can be seen from the above, this design can prevent the bracket from suddenly bouncing upwards under the elastic potential energy of the first elastic buffer when the pressing plate is separated from the bracket or the turntable, prevent the printed circuit board on the bracket from being separated from the turntable, and enable the bracket to be smoothly reset.

[0018] Another preferred solution is that a first anti-misalignment part is provided in the first accommodation position, a second anti-misalignment part is provided on the turnover turntable, and the first anti-misalignment part is cooperatively connected with the second anti-misalignment part; a first handle is provided on the turnover turntable, or a holding part is formed on the turnover turntable.

[0019] As can be seen from the above, through the anti-misalignment structure design between the first accommodation position and the turnover turntable, it is possible to avoid the situation that the printed circuit board cannot be burned or the printed circuit board is burned due to the misloading of the turnover turntable; and the design of the first handle or the holding part on the turnover turntable facilitates the operator to pick up and place the turnover turntable.

[0020] A further solution is that the carrier includes a carrier board and a seat body. The frame body and the needle board are both installed on the carrier board. A third avoidance opening penetrating through itself is provided on the carrier board. The needle board passes through the third avoidance opening. The seat body has an accommodation chamber. The carrier board is hinged to the seat body and covers the opening of the accommodation chamber. The burner is installed on the seat body.

[0021] As can be seen from the above, this design facilitates hiding and protecting the wiring between the needle board and the burner, and improves the aesthetics of the burning device.

[0022] An even further solution is that the number of probe assemblies is more than two groups, the number of burners is more than two, more than two burners correspond to more than two groups of probe assemblies one by one, the number of second accommodation positions is more than two, and more than two second accommodation positions correspond to more than two groups of probe assemblies one by one; more than two first interfaces are provided on the needle board, and more than two first interfaces correspond to more than two groups of probe assemblies one by one. The burner is provided with a second interface, and the second interface is cooperatively connected with a corresponding first interface; the needle board and the carrier board are connected by a wing bolt; a buckle is provided between the carrier board and the seat body; a second handle is provided on the seat body, or a handle part is formed on the seat body.

[0023] As can be seen from the above, through the quantity design of the probe assembly, the burner, the second accommodation position, etc., the burning device can process and burn more than two printed circuit boards at a time, which is beneficial to improving the processing efficiency of the burning device; setting the first interface on the needle board is beneficial to the quick connection between the probe assembly and the burner; using a wing bolt to assemble the needle board and the carrier board is beneficial to quickly disassembling and assembling the two without the aid of special tools, making the replacement of the needle board more convenient and easy to operate; setting a buckle between the carrier board and the seat body can improve the reliability of the connection between the two, and combined with the hinged connection method between the two, the connection between the two is more convenient and easy to operate; setting a second handle or a handle part on the seat body is beneficial to carrying the burning device.

[0024] To achieve another object of the present invention, the present invention provides a production line, which includes the above-mentioned burning device.

[0025] As can be seen from the above, the production line equipped with the above-mentioned programming device is conducive to shortening the production cycle, reducing the production cost and improving the convenience of the programming process. Description of the Drawings

Preferably, a handle portion 1223 can be formed on the base body 122 of the carrier 12, or a second handle can be installed on the base body 122, making it more convenient to carry the programming device 100.

[0039] Combined with Figure 4 , the needle board 2 is detachably installed on the top of the carrier 12. The needle board 2 is provided with a probe assembly 21. The probe assembly 21 is used for electrically connecting with the programmer 3 and the programming sites on the printed circuit board, so that the programmer 3 can process and program the printed circuit board. Specifically, in this embodiment, both the frame body 11 and the needle board 2 are installed on the carrier board 121 of the carrier 12, and the carrier board 121 is connected to the guide post group 13. Among them, a third avoidance opening 1211 is provided on the carrier board 121. The third avoidance opening 1211 penetrates the carrier board 121 in the height direction of the frame 1, so that the third avoidance opening 1211 communicates with the receiving chamber 1221 of the base body 122. The needle board 2 passes through the third avoidance opening 1211 from the inner side (i.e., the side close to the receiving chamber 1221) of the carrier board 121 to the outside of the carrier board 121, so that part of the needle board 2 and the probe assembly 21 are located outside the carrier board 121. Preferably, the needle board 2 and the carrier board 121 are connected by a wing nut, and the wing operation part 4122 of the wing nut is located in the receiving chamber 1221 to improve the aesthetics of the programming device 100; and connecting the needle board 2 and the carrier board 121 by a wing nut is conducive to realizing the quick disassembly and assembly of the two, and no special tool is required, making the replacement of the needle board 2 more convenient and easy to operate.

[0041] Combined with Figure 5 , in this embodiment, the pressing mechanism 4 includes a driving unit 41, a pressing plate 42 and a sliding plate 43. The driving unit 41 is installed on the frame body 11; a thimble assembly 421 is provided on the pressing plate 42, and the pressing plate 42 is detachably installed on the sliding plate 43. Preferably, the pressing plate 42 and the sliding plate 43 are connected by a wing bolt, so that the disassembly and assembly of the pressing plate 42 are more convenient and easy to operate, and no special tool is required for disassembly and assembly; the sliding plate 43 is slidably installed on the guide post group 13, so that the sliding plate 43 can slide along the guide post group 13 in the height direction of the frame 1. The setting of the sliding plate 43 can improve the smoothness of the driving unit 41 driving the pressing plate 42 to move, and ensure that the thimble assembly 421 on the pressing plate 42 can be more accurately pressed on the preset pressing site on the printed circuit board, thereby ensuring the stability and reliability of the processing and programming.

[0042] The driving end of the driving unit 41 is preferably connected to the pressing plate 42 to drive the pressing plate 42 to move relative to the needle board 2 in the height direction of the frame 1; of course, as another alternative solution, in other embodiments, the driving end of the driving unit 41 can also be connected to the sliding plate 43.

In addition, as another alternative solution, in other embodiments, the driving unit 41 can also be a linear slide table, an electric cylinder or a cylinder. It can be seen that the driving unit 41 can be set to be manual or automatic according to usage requirements, usage conditions, production costs, etc., thereby improving the practicability and design flexibility of the programming device 100 and expanding the applicable range of the programming device 100.

[0043] The bracket 5 is installed on the frame 1. In this embodiment, the bracket 5 is slidably installed on the guide post group 13, which is beneficial to improving the reliability and stability of the contact between the probe assembly 21 and the programming site on the printed circuit board. Preferably, the frame 1 further includes a first elastic buffer 14 and a third elastic buffer 15; the first elastic buffer 14 is used to force the bracket 5 to slide away from the needle board 2. The first elastic buffer 14 preferably adopts a compression spring. The compression spring is sleeved on the guide posts of the guide post group 13, and the two ends of the compression spring are respectively abutted against the needle board 2 and the bracket 5. The first elastic buffer 14 can buffer when the printed circuit board placed on the bracket 5 contacts the probe assembly 21, avoiding direct hard contact between the probe assembly 21 and the programming site of the printed circuit board, thereby playing a protective role for the probe assembly 21 and the printed circuit board; the third elastic buffer 15 is used to force the bracket 5 to slide towards the needle board 2. The third elastic buffer 15 preferably adopts a compression spring. The compression spring is sleeved on the guide posts of the guide post group 13, and the two ends of the compression spring are respectively abutted against the sliding plate 43 and the bracket 5. The third elastic buffer 15 can prevent the bracket 5 from suddenly bouncing upward under the action of the elastic potential energy of the first elastic buffer 14 when the pressure plate 42 is separated from the bracket 5 or the turntable 6, prevent the printed circuit board on the bracket 5 from detaching from the turntable 6, and enable the bracket 5 to be smoothly reset.

[0044] Combined with Figure 6 , the bracket 5 is provided with a first accommodation position 51. The bottom of the first accommodation position 51 is provided with a first avoidance opening 512. The first avoidance opening 512 penetrates the bracket 5 in the height direction of the frame 1, and the first avoidance opening 512 is arranged opposite to the probe assembly 21. The first avoidance opening 512 is used to avoid the probe assembly 21.

[0045] Combined with Figure 7 , the turntable 6 is provided with a second accommodation position 61. The second accommodation position 61 is used to accommodate the printed circuit board and position the printed circuit board; the bottom of the second accommodation position 61 is provided with a bottom second avoidance opening 611. The second avoidance opening 611 penetrates the turntable 6 in the height direction of the frame 1. The second avoidance opening 611 is used to avoid the probe assembly 21, so that the probe assembly 21 can contact the programming site on the printed circuit board; the turntable 6 is detachably placed in the first accommodation position 51. When the turntable 6 is placed in the first accommodation position 51, the second avoidance opening 611 is arranged opposite to the probe assembly 21. When the driving unit 41 drives the pressure plate 42 and the movable plate to move towards the needle board 2, the pressure plate 42 can press the turntable 6 against the bracket 5, and press the printed circuit board in the second accommodation position 61 through the thimble assembly 421. When the driving unit 41 continuously drives the pressure plate 42 and the movable plate to move towards the needle board 2, the pressure plate 42 will push the bracket 5 and the turntable 6 to move towards the needle board 2 until the probe assembly 21 contacts the programming site of the printed circuit board.

[0046] Preferably, a first anti-fooling portion 511 is provided in the first accommodation position 51 of the bracket 5, and a second anti-fooling portion 63 is provided on the turntable 6. When the turntable 6 is placed in the first accommodation position 51, the first anti-fooling portion 511 is cooperatively connected with the second anti-fooling portion 63 to prevent the wrong installation of the turntable 6, thereby preventing the printed circuit board from not being burned or the printed circuit board from being burned. In addition, a holding portion 64 can be formed on the turntable 6, or a first handle can be installed on the turntable 6 to make it more convenient and easy for the operator to pick up and place the turntable 6.

[0047] Combined with Figure 8 , a positioning pin 431 is preferably further provided on the sliding plate 43. The positioning pin 431 extends towards the turntable 6 parallel to the height direction of the frame 1; a positioning hole 62 matching the positioning pin 431 is provided on the turntable 6. When the pressing plate 42 and the sliding plate 43 move towards the bracket 5 and the turntable 6, the positioning pin 431 can be inserted into the positioning hole 62 to position and fix the turntable 6, thereby ensuring the relative position accuracy between the printed circuit board and the probe assembly 21 and the thimble assembly 421, and thus ensuring the stability and reliability of the processing and burning. Among them, the positioning hole 62 can penetrate the turntable 6 in the height direction of the frame 1. When the positioning hole 62 penetrates the turntable 6, the positioning pin 431 abuts against the bracket 5; when the positioning hole 62 does not penetrate the turntable 6, the positioning pin 431 abuts against the carrier 6.

[0048] Preferably, the positioning pin 431 is slidably connected to the sliding plate 43 in the height direction of the frame 1. When the positioning pin 431 is in a non-contact state (that is, the positioning pin 431 does not contact the bracket 5 or the turntable 6), the first distance L1 between the bottom of the positioning pin 431 and the bracket 5 is less than the second distance L2 between the bottom of the thimble assembly 421 and the bracket 5, so that when the pressing plate 42 and the sliding plate 43 slide towards the bracket 5 and the turntable 121, it is ensured that after the positioning pin 431 abuts against the bracket 5 or the turntable, the thimble assembly 421 abuts against the printed circuit board on the turntable 6, thereby ensuring the reliability of the positioning and fixing of the turntable 6 by the positioning pin 431. In addition, the pressing mechanism 4 preferably further includes a second elastic buffer 44. The second elastic buffer 44 is used to force the positioning pin 431 to slide towards the bracket 5. The second elastic buffer 44 preferably adopts a compression spring. The compression spring is sleeved on the positioning pin 431 and is connected between the positioning pin 431 and the sliding plate 43; the second elastic buffer 44 can buffer the positioning pin 431 when the positioning pin 431 contacts the bracket 5 or the turntable 6, avoiding direct hard contact between the positioning pin 431 and the bracket 5 or the turntable 6.

[0049] Further, the number of probe assemblies 21 on the needle plate 2 is two or more; the number of burners 3 is two or more, and the two or more burners 3 correspond to the two or more probe assemblies 21 one by one; the number of second receiving positions 61 on the rotary carrier is two or more, and the two or more second receiving positions 61 correspond to the two or more probe assemblies 21 one by one; in addition, the number of first interfaces 211 on the needle plate 2 is two or more, and the two or more first interfaces 211 correspond to the two or more probe assemblies 21 one by one; this design enables the burning device 100 to process and burn two or more printed circuit boards at a time, thereby improving the processing efficiency of the burning device 100.

[0050] In summary, through the design of the burning device 100, the rotary turntable 6 can be a carrier and fixture used for turning and processing printed circuit boards during the production process. As long as the outer contour dimensions of different rotary turntables 6 applicable to different models of printed circuit boards are basically the same, when changing the model of the printed circuit board to be burned, the burning device 100 can process and burn different models of printed circuit boards only by replacing the rotary turntable 6, the needle plate 2 and the pressing plate 42; and by using the combination of the bracket 5 and the rotary turntable 6 to replace the existing burning rack, the burning device 100 has higher flexibility and stronger practicability. When changing the model of the printed circuit board, the rotary turntable 6 used during the turnover and / or processing of the printed circuit board can be directly installed on the bracket 5, thus eliminating the need for additional custom-made trays specifically for the processing and burning of printed circuit boards, effectively reducing the production cost, shortening the production cycle of the product, and improving the production efficiency; furthermore, when replacing the rotary turntable 6, there is no need to remove the peripheral mechanism of the rotary turntable 6, reducing the difficulty of replacing the rotary turntable 6.

[0051] Second Embodiment of the Burning Device

[0052] The difference between this embodiment and the first embodiment of the burning device is that in this embodiment, the bracket is directly fixedly installed on the carrier board of the stage, and the settings of the first elastic buffer and the third elastic buffer are cancelled. This design can reduce the volume of the burning device, reduce the number of parts, assembly difficulty and production cost of the burning device.

[0054] The production line includes the burning equipment described in the first embodiment or the second embodiment of the above-mentioned burning equipment. In addition, the production line may further include a feeding mechanism (such as a belt transmission mechanism or other structures with a feeding function, etc.).
