Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a partitioned welding workbench and welding equipment. Background Art

[0002] When soldering an electronic device to a substrate, the substrate is usually placed on a soldering workbench with a heating function before soldering. Specifically, the soldering workbench can preheat the solder pads on the substrate, which is conducive to quickly bonding the solder to the solder pads.

[0003] When there are multiple pads on the substrate that need to be welded, the welding head can only weld one pad at a time. Since the entire substrate is placed on the welding workbench, all the pads on the entire substrate will be heated. Even if the welding head is welding the pads behind, the soldering of the pads that have been welded in front is still heated, and the solidification speed of the solder is slowed down. Often, it is still in an unsolidified state. During this process, if the substrate is moved, it is likely to cause the electronic components to shift, and eventually poor welding will occur.

[0004] Therefore, it is necessary to improve the existing welding workbench to solve the problems of low solder solidification speed and easy displacement of electronic components.

[0005] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art.

[0037] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0039] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0040] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0041] The utility model provides a partitioned welding workbench and welding equipment, which are suitable for the application scenario of welding and fixing electronic devices on the welding pads of a substrate, and can effectively solve the problems of low solder solidification speed and easy displacement of electronic devices on the existing partitioned welding workbench.

[0042] In this embodiment, the welding equipment includes a welding head and a partitioned welding workbench.

[0043] See also Figure 1 The partitioned welding workbench includes a variable temperature heating platform 1, a heating linear drive mechanism 2, a transfer component 3, a platform base plate 4, and a cross sliding platform 5.

[0044] The heating linear drive mechanism 2 and the transfer linear drive mechanism 302 are both installed and fixed on the platform base plate 4, and the platform base plate 4 is installed and fixed on the cross sliding platform 5. The cross sliding platform 5 can control the forward, backward, left and right movement of the platform base plate 4 so as to move the substrate to directly under the welding head, which is beneficial to the welding operation of the welding head.

[0045] Specifically, see Figure 2 The variable temperature heating platform 1 includes a lifting plate 101 , a first heater 102 a installed at the bottom of one end of the lifting plate 101 , and a second heater 102 b installed at the bottom of the other end of the lifting plate 101 .

[0046] Furthermore, one end of the lifting plate 101 is a high heat zone 1011 , and the other end is a low heat zone 1013 . A welding operation zone 1012 is located between the high heat zone 1011 and the low heat zone 1013 , and a welding head can perform welding operations in the welding operation zone 1012 .

[0047] Specifically, a first heater 102a is provided below the high heat zone 1011 and the welding work zone 1012; a second heater 102b is provided below the low heat zone 1013; wherein the heating power of the first heater 102a is greater than the heating power of the second heater 102b, therefore, the temperatures of the high heat zone 1011 and the welding work zone 1012 are higher, and the temperature of the low heat zone 1013 is lower.

[0048] The temperature of the high heat zone 1011 is relatively high. Placing a substrate that has not been soldered in the high heat zone 1011 can preheat the substrate so that the solder pads on the substrate can be quickly combined with the solder after heating up. The temperature of the low heat zone 1013 is relatively low, and the heating effect on the substrate is almost negligible. Therefore, transferring the substrate that has been soldered to the low heat zone 1013 can avoid the situation where the solder cannot solidify due to the excessive heating temperature of the variable temperature heating platform 1.

[0049] The driving end of the heating linear driving mechanism 2 is connected to the variable temperature heating platform 1 to drive the variable temperature heating platform 1 to move up and down.

[0050] The transfer assembly 3 includes a clamping unit 301 for clamping a substrate and a transfer linear drive mechanism 302 for driving the clamping unit 301 to reciprocate between the high heat zone 1011 and the low heat zone 1013 .

[0051] See also Figure 3 , wherein the clamping unit 301 includes a clamping base plate 3011, a fixed pressure plate 3012, a floating pressure bar 3013, and a floating linear drive mechanism 3014.

[0052] The fixed pressing plate 3012 is located above the clamping base plate 3011 and is fixedly arranged relative to the clamping base plate 3011. Furthermore, a through groove 3012a for welding head to unload is provided in the middle position of the fixed pressing plate 3012.

[0053] The floating pressure strip 3013 is located below the clamping bottom plate 3011. The driving end of the floating linear driving mechanism 3014 is connected to the floating pressure strip 3013, and is used to drive the floating pressure strip 3013 to move up and down relative to the fixed pressure plate 3012.

[0054] It should be noted that the linear drive mechanisms mentioned in the present invention may be air cylinders, hydraulic cylinders, electric cylinders, motor belt assemblies or motor screw linear modules, etc. The present invention does not limit the specific structural form of the linear drive mechanisms.

[0055] The welding equipment provided in this embodiment has a detailed working process as follows:

[0056] S10: The upstream equipment places the substrate on the high heat zone 1011 for preheating;

[0057] S20: After the preheating is finished, the transfer linear drive mechanism 302 drives the clamping unit 301 to move to the high-heat zone 1011; at this time, the fixed pressing plate 3012 is located above the base, and the floating pressing bar 3013 is located below the base;

[0058] S30: The floating linear drive mechanism 3014 drives the floating pressure bar 3013 to move upward, and cooperates with the bottom surface of the fixed pressure plate 3012 to press the edge of the substrate; at this time, the pad on the substrate is exposed through the through groove 3012a of the fixed pressure plate 3012, so as to facilitate subsequent welding operations;

[0059] S40: the heating linear drive mechanism 2 drives the variable temperature heating platform 1 to move downward and away from the substrate; then, the transfer linear drive mechanism 302 drives the clamping unit 301 to move to the welding operation area 1012; then, the heating linear drive mechanism 2 drives the variable temperature heating platform 1 to move upward and fit the substrate, so as to continue to heat the substrate;

[0060] At the same time, the upstream equipment places a new substrate on the high-heat zone 1011 for preheating;

[0061] S50: the cross sliding platform 5 moves forward and backward so that the welding head can be arranged opposite to the corresponding welding pad;

[0062] S60: The welding head welds the electronic device to the substrate through the through groove 3012a;

[0063] S70: The heating linear drive mechanism 2 drives the variable temperature heating platform 1 to move downward and away from the substrate; then, the transfer linear drive mechanism 302 drives the clamping unit 301 to move to the low heat zone 1013; then, the floating linear drive mechanism 3014 drives the floating pressure bar 3013 to move downward and release the substrate; at this time, the substrate is placed on the low heat zone 1013, where the temperature is not high and will not affect the normal solidification of the solder;

[0064] After normal solidification, the substrate can be removed by downstream equipment;

[0065] In some other embodiments, when there are multiple rows of pads on the substrate, assuming that the substrate is welding the pads in the Nth row, step S70 first moves the pads in the Nth row to the low-heat zone 1013 for cooling, and then moves the pads in the N+1th row to the welding work area 1012 for welding. At this time, the pad row change action is completed by the transfer linear drive mechanism 302. The row change error in this step is compensated by the Y-axis movement in the cross sliding platform 5. When all pads are welded and the solder is completely solidified, the material can be transferred to the lower computer;

[0066] S80: The linear drive mechanism 302 is transferred to drive the clamping unit 301 to move back to the high-heat zone 1011 again, and the above steps S10-S70 are repeated to complete the next welding operation.

[0067] The partitioned welding workbench and welding equipment provided in this embodiment have the following advantages: the substrate before welding is placed in the high-heat zone 1011 for preheating to increase the temperature of the welding pad, and the substrate after welding is placed in the low-heat zone 1013 for standing to allow the solder to solidify, thereby effectively solving the problem of low solder solidification speed and easy displacement of electronic components in the existing partitioned welding workbench.

[0068] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0069] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
